虚拟语气
虚拟语气在动词advise,suggest,propose,direct,insist,ask,request,demand,require,order,recommend,command,urge,desire,determine,decide,intend,move,vote等表示“建议,要求,命令…”等动词后的that-从句中用“(should)+动词原形”(should可以省略)。另外“It is + 动词过去分式 + that”结构中,动词仍是以上这些动词,在that-从句中用“(should)+动词原形”(should可以省略)。
举例:
1) It is politely requested by the hotel management that radios           after 11:00 p.m.
A) were not played       B) not to play      C) not be played      D) did not play
2) He suggested          to tomorrow’s exhibition together.
A) us to go              B) we went          C) we shall go        D) we go
虚拟语气在表示“建议,要求,命令,主张,目的,愿望”,如:suggestion, proposal, demand, recommendation, request, advice, decision, motion, preference, word, order, desire, necessity, decree, instruction, resolution等这类名词后的表语从句或同位语从句中,用“(should) + 动词原形”。
举例:
1) We are all for your proposal that the decision           .
A) be put off           B) was put off     C) should put off     D) is to put off
虚拟语气在It is + adj. + that 结构中的that-从句中用“(should) + 动词原形”,这类形容词有:important, vital, crucial, necessary, appropriate, better, desirable, imperative, insistent, natural, preferable, strange, urgent, fitting, impossible, obligatory, proper等。
举例:
1) I don’t think it advisable that Tim         to the job since he has no experience.
A) is assigned      B) will be assigned    C) be assigned    D) has been assigned
2) It is essential these application forms          back as early as possible.
A) must be sent     B) will be sent       C) are sent       D) be sent
虚拟语气在连接词lest引导的从句中,lest作“害怕,以免”解,其引导的谓语从句应用“(should) + 动词原形”。有类似从用法的连词还有:for fear that, in case。如:
He took his raincoat with him in case it should rain.他带上了雨衣以防下雨。
She put a blanket over the baby for fear that he should catch cold.
她在那个婴儿身上盖上了毯子以免他着凉。
举例:
1) The mad man was put in the soft-padded cell lest he          himself.
A) injure           B) had injured         C) injured       D) would injure
2) He was punished              he should make the same mistake again.
A) unless           B) provided            C) if            D) lest
虚拟语气在would  rather(had rather, would just as soon)表示“希望,宁愿”时,其后的从句中,用一般过去时表示现在或将来的愿望。如:
I’d rather you posted the letter right away.我倒希望你把这封信立即寄出。
I would just as soon you had returned the book yesterday.我真希望你昨天把这本书还了。
但如果句子主语不是对他人而是对自己的行为表示某种愿望或感叹,其谓语形式有两种情况:1、表示现在情况用would rather + do;2、表示过去情况用would rather + have done.如:
I would rather buy a house with a garden.我真希望买一座带花园的房子。
She would rather not have gone to the party.她觉得真是不该去参加那个晚会。
另外还有would sooner,从句用过去时表示尚未发生的动作;用过去完成时表示对已发生的动作的某种愿望。
举例:
1) You don’t have to be in such a hurry, I would rather you     on business first.
A) would to       B) will go              C) went           D) have gone
wish作“希望”解,其后的宾语从句中,(1)同时。表示与现在情况相反的愿望,谓语动词用动词过去式(包括进行体),即that主语 + V-ed(be动词用were);(2)先时。表示与过去情况相反的愿望时,用had + 过去分词(有时根据意思要用could have + 动词过去分词);(3)后时。表示与将来情况可能相反的愿望,用would + 动词原形。如:
I wish I were as young as you.(同时)
我要是和你一样年轻就好了。
I wish that he had not made so much fuss about it.(先时)
但愿那时他对这事不那么大惊小怪了。
It was wished that they would make greater progress.(后时)
那时人们希望他们能取得更大的进步就好了。
举例:
1) Sometimes I wish I       in a different time and a different place.
A) be living      B) were living         C) would live     D) would have lived
2) I wish I         longer this morning, but I had to get up and come to class.
A) could have slept    B) slept         C) might have slept      D) have slept
3) Jack wishes that he        business instead of history when he was in university.
A) had studied    B) study               C) studied        D) had been studying
if only作“要是……就好了”解,相当于“How I wish + 宾语从句”,它引导的感叹句中,(1)表示与现在事实相反的愿望,谓语动词用过去式;(2)表示将来不大可能实现的愿望用would/could +动词原形;(3)与过去事实相反用过去完成式。
举例:
1) Look at the terrible situation I am in! If only I        your advice.
A) follow         B) had followed         C) would follow    D) have followed
2) If only the committee      the regulations and put them into effect as soon as possible.
A) approve        B) will approve         C) can approve     D) would approve
It is (high/about) time (that)…作“(早)该是…的时候了”解,后跟句子中的谓语动词用过去式。
It is (has been) … since…后跟句子中的谓语动词用过去式。
This is the first (second) time that …后跟句子中的谓语动词用现在完成时 (have done)。
举例:
1) “You are very selfish. It is high time you         that you are not the most important person in the world.” Edgar said to his boss angrily.
A) realized       B) have realized        C) realize         D) should realize
2) It is already 5:00 p.m. now. Don’t you think it’s about time         ?

虚拟条件句
 
 If条件句 主句   
与现在事实相反 动词过去式(be动词一般都用were) should, would, could, might + 动词原形   
与过去事实相反 had + 动词过去分词 should, would, could, might + have + 动词过去分词   
与将来时间相反 were to + 动词原形
should + 动词原形 should, would, could, might + 动词原形 
注:在主句中,一般只有主语为第一人称时使用should。
当if从句中有were, had, should这样的助动词或情态动词时,可以省略if, 用主语倒装形式。
举例:
1) Had he worked harder, he       the exams.
A) must have got through              B) would have got through

3) If the whole operation        beforehand, a great deal of time and money would have been lost.
A) was not planned                   B) has not been planned

有时假设的情况不是以条件从句的形式表示出来的,而是通过介词或介词短语,如:with, without, but for, but that(假使不…,要不是…), save that, except for等,或由连词but, or,副词otherwise, only等或通过上下文以及其他形式表现出来。
举例:
1) We didn’t know his telephone number, otherwise we         him.
A) would have telephoned             B) must have telephoned
C) would telephone                   D) had telephoned
If it (be) nor for是常见的虚拟条件句,意思是“要不是…”,相当于but for 和without。如:
If it were not for the leadership of the Party, we could not be living a happy life today.
要不是有了党的领导,我们今天就不可能过上幸福生活了。
If it had not been for your help, we would not have achieved so much in our work.
要不是有了你的帮助,我们工作中不会取得如此大的成绩。
Without electricity, there would be no modern industry.
没有电就不会有现代工业。
But for your cooperation, we could not have succeeded in our experiment.
没有你们的帮助,我们的试验是不可能成功的。
But that she was afraid, she would have said no.要不是害怕的话,她就会拒绝了。
It is + 形容词或过去分词 + 主语从句。这类形容词或分词有:essential(必要的), urgent(紧迫的), necessary(必要的), important(重要的), advisable(合理的), asked(要求), desired(希望的), natural(自然的), desirable(理想的), demanded(要求的), preferable(更好的), imperative(迫切的), ordered(命令的), required(要求的), suggested(建议的)。如:
It was required that the crops should be harvested at once.

他们要求,必须马上收割那些庄稼。
as if/as though,其用法与wish完全相同。如:

她爱幼儿园里的孩子好像他们是她自己孩子拨似的。
Alan talked about Rome as if he had been there.
艾伦谈起罗马来好像他是个罗马人似的。

一致关系
一致关系表现在语法一致、意义一致和毗邻一致三个方面。
The number of errors was surprising.            (语法一致)
The committee are unable to reach a decision.   (意义一致)
Either my sisters or my father is coming.       (毗邻一致)
主谓一致是指谓语动词在人称和数上必须和主语一致。
There be 句型中,如果主语为并列结构,谓语通常与并列结构中的第一个成分相一致,即取决于靠近动词的那个名词。如:
There is still plenty of wine in the bottle.瓶里还有不少酒。
There are plenty of books on the shelf.书架上有多书。
be动词还可以与情态动词或其他动词连用,there may be, there can be, there must be, there seems to be, there appears to be, there happened to be。有时该结构不是用的动词be, 而是用了表示状态的其他动词,如there exit, there stand, there remain等。
举例:
1) There is a sausage, two oranges and a piece of these on the table.
2) There is food and drink enough for everyone.
3) The owner and editor of the newspaper         the conference.
A) were attending     B) were to attend     C) is to attend       D) are to attend
解析:由and连接两个名词的并列结构做主语时,如果第一个词前面有定冠词the,而第二个词前面没有,则表示为同一个人或物,谓语动词用单数;如果第一个词和第二个词前面都有定冠词the,则表示不同的人或物,谓语动词用复数。
neither做主语时,表示对二者的否定,动词必须用单数形式。如:
举例:
1)      of the two books holds the opinion that the danger of unclear war is increasing.
A) None               B) Either             C) Both               D) Neither
解析:none只能用于三者或三者以上的否定,而either 应与or连用,both可用于二者的肯定情况,但其后的谓语应用复数。
2) Neither of the young men who had applied for a position in the university      .
A) has been accepted  B) have been accepted   C) was accepted    D) were accepted
名词作主语与谓语一致:
l 集合名l 词作主语,l 如表示整体概念则用单数谓语形式,l 如表示成员则用复l 数谓语形式。这类名l 词有:army, audience, class, club, committee, company, crowd, couple, family, group, government, jury, party, personnel, staff, team, union, public等。如:
    The football team consists of 20 players.这个足球队由20名成员组成。
The football team are having a bath now. 足球队员们正在洗澡。
有些集合名词如:cattle, folk, militia, people, police, poultry, youth等,总是跟复数动词形式。如:
The police have caught the murderer. 警察抓住了凶手。
单复数形式的名词作主语,要根据意义来决定谓语的形式。常见的名词有:aircraft, deer, fish, means, sheep, species, series, works, crossroads, headquarters等。如:
The species of fish are numerous.鱼的种类繁多。
This species of rose is very rare.这种玫瑰花很稀罕。
复数名词用作专有名词时,用单数谓语。如:
The United States was founded in 1776. 美国成立于1776年。
“the + 形容词”作主语,如表示一类可数的人或事物时,用复数谓语,如表示一类不可数的事物时,用单数。如:
The old are well looked after by the government.政府对老年人照顾得很好。
The agreeable is not always the useful.好看的不一定实用。
表示成双成对的东西的名词,若被a pair of修饰,要求接单数谓语形式;否则,用复数谓语形式。如:
These trousers are made in Shanghai.这些裤子是上海生产的。
This pair of trousers is made in Shanghai.这条裤是上海生产的。
连接词连接的主语与谓语的一致:
l 用“and”连接的两个名l 词作主语,l 如果指同l 一个人或物时,l 用单数形式,l 如果指l 不同l 的或物,l 则用复l 数形式。如:
The secretary and manager was present at the meeting.
那位书记兼经理出席了会议。
The secretary and the manager were present at the meeting.
书记和经理都出席了会议。
用both…and连接两个名词作主语,其谓语用复数形式。如:
Both the secretary and manager have agreed to be present.
书记和经理都已同意出席会议。
如果主语是and连接的两个单数名词,前面如有each, every, many a, no等修饰时,谓语用单数形式。如:

许多男孩和女孩都看了这幅油画。
单数名词 + with, along, with, together, with, combined with, as well as, rather than等所跟的名词作主语时,谓语仍用单数形式。如:

One or two friends are coming this evening.今天晚上有一两个朋友要来。
(5)“代词”以及“限定词+名词”作主语:
all, half, most, none, some以及the remainder (of), the rest (of), plenty (of)等代词作主语时,其主谓语单、复数形式要根据它们所代替的词的含义来确定。如:
Most of his spare time was spent in reading.他的大部分业余时间都花在读书上。
Most of the houses in this town are new.这个镇上的大多数房屋是新的。
Half of the oranges are bad.一半的桔子烂了。
Half of the food is unfit to eat.一半的食物不能吃了。
both ,(a) few, many, several等限定词修饰的主语,要用复数谓语形式。如:

由合成代词some(any, no every) + thing (body, one)作主语,由代词each, every one, no one, either, neither, another, the other 作主语,以及由限定词either, neither, each, every, many a, more than one等 + 名词作主语时,跟单数谓语形式。如:

除了我父母亲以外,没有人知道这件事。
在one of + 复数名词 + 定语从句,谓语用复数形式。如:

但在the only one of + 复数名词 + 定语从句,谓语用单数形式。如:
He was the only one of the boys who was given a prize.
他是这些孩子中唯一受到奖励的。
在 “代词 + 定语从句”结构中,谓语形式要与所修饰的代词保持一致。如:

A) be          B) am           C) being             D) is

What you said is quite to the point.你所说的非常中肯。
What we need are qualified teachers.我们需要的是合格的教师。
(6) 数词、量词等作主语与谓语的一致。
l 用作运算的数词作主语时,l 其谓语常用单数形式。如:

Three multiplied by four is twelve.三乘四等于十二。
Eight minus three is equal to five.八减三等于五。

Ten thousand dollars is quite a large sum.一万美金是相当大的一笔款子。
分数和百分数作主语时,谓语形式是单还是复要取决它们表示的意义。如:

这些书中大约有三分之一值得读一读。
A large percentage of the wheat crop was ruined by the flood.
大部分的麦类作物遭到洪水的毁坏。
由kind (form, type, sort, species, portion, series, quantity) of修饰的主语,其谓语形式取决于这些词的单、复数,而不是后面所跟的名词。如:

All kinds of difficulties have to be overcome.必须克服各种各样的困难。
a number of (许多),a variety of(各种各样)和a group of (一群,一组)修饰名词作主语,谓语要求用复数形式。但the number of(数目)和the variety of(种类)修饰名词作主语,谓语用单数形式。如:

一些固定搭配,如:be supposed to (应该,被认为,被期望),be reported to (据报道),be said to do(据说)等。
跟不带to的不定式作宾补的动词:see, hear, look at, listen to, feel, observe, watch, notice等感官动词,以及let, make, have等其他动词后面,作宾补的不定式均省去to。如:
The teacher makes us write a composition every week.
那个老师让我们每星期写一篇文章。
在had better, would rather…(than), would…rather than, would sooner…(than), can not but…, can’t help but…, may(might) as well…等习惯用法中,使用不带to的不定式。如:
Rather than beg in the street, he would prefer to die of hunger.
他宁愿饿死也不上街乞讨。
在do nothing/anything/ everything but (except)结构中使用不带to的不定式。如:
Last night I did nothing but watch TV. 昨天晚上,我除了看电视别的什么也没有干。
但如果谓语动词不是do nothing/anything/ everything,那么but (except)所跟的不定式则仍须带to,如:
There was nothing for them to do but to remain silent.
除了保持沉默以外,他们没有别的办法。
不定式还常常用于构成复合谓语结构:
1) be said (reported, known等) + 不2) 定式。如:
Shanxi Province is known to have rich coal reserves.
据了解山西省有丰富的煤炭资源。(=It is known that Shanxi has rich coal reserves.)
3) seem (happen, appear, prove, tend等) + 不4) 定式。如:

5) be likely(certain, sure, willing, anxious, ready, bound, eager, reluctant等) + 不6) 定式。如:
She is always ready to help others.她总是乐于帮助他人。
不定式还常与in order to, so as to连用,作目的状语;与so(或such)…as to连用,作目的状语和结果状语。与enough和too…to连用,作程度状语。如:
In order to catch the train, he hurried through his work.
为了赶火车,他匆匆干完了工作。
He is too young to travel alone.他太年轻了,不能一人独自旅行。
某些动词如:wish, hope, intend, mean, plan以及be等动词的过去式后面跟有一定不定式的完成式,可以表示事实上并未实现的行为。即:过去式 + to have done。如:
I was to have returned you the book, but I was too busy that day.
我本来要将那本书还你的,可是我那天太忙了。
举例:
1) Mrs. Brown is supposed         for Italy last week.
A) to have left          B) to be leaving     C) to leave       D) to have been left
(6) 连接词 + 不定式
1) Everyone had an application form in his hand, but no one knew which office room      .

举例:
1) The teacher doesn’t permit       in class.

分  词
 
 及物动词write 不及物动词主动语态    
 主动语态 被动语态     
现在分词  一般式 writing being written going   
  完成式 having writing having been written having gone   
过去分词  written gone 
现在分词和过去分词主要区别表现在语态和时间关系上。语态上:现在分词表示主动的意思,而过去分词表示被动的意思。时间关系上:现在分词所表示的动作往往正在进行,而过去分词所表示的动作,往往已经完成。
catch sb. doing sth. 表示当动作正在进行时被抓住。适合此结构的动词还有表示感觉的:see(看见), hear(听见), feel(感觉到), smell, watch, catch(偶然发觉), find(发现), notice(注意到), observe(观察), look at, listen to ,perceive等。
举例:
1) When I caught him       me I stopped buying things there and started dealing with another shop.
A) cheat         B) cheating               C) to cheat            D) to be cheating
keep sb. done这类表示“致使”意义的动词还有have, start, keep, get, set, stop, send, leave等,以及表示爱僧、意愿的动词,如dislike, hate, love, like等。
举例:
1) The president promised to keep all the board members       of how the negotiations were going on.
A) informed      B) inform                C) be informed         D) informing
过去分词作宾补,表示被动的动作,want sth. done,意为“让别人做这件事”。have sth. done “表示某件事是由别人去做的,而不是自己亲自去做的”have sb. do sth. 表示“让某人干某事”。
举例:
1) If you want          you have to get the fund somewhere.
A) that the job is done                   B) the job done
C) to have done the job                   D) the job that is done
形容词、副词的比较级
没有比较等级变化的形容词或副词:anterior(前面的), posterior(以后的), superior(较优的), inferior(较劣的), junior(年少的), senior(年长的), prior(顺序在先的)。这类词本身就含有比较的意思在内,所以没有比较级和最高级,也无需在前面再加上more,但要在后面加上介词to。
举例:
1) Beethoven is my favorite musician, I regard him as        other musicians.
A) superior to    B) more superior than     C) more superior to      D) superior than
2) Germans used to believe that all other races were inferior        them.
A) than           B) for                    C) to                    D) from
同级比较:as + 形容词或副词原级 + as(和……一样地);否定形式:not as (so) + 形容词或副词原级 + as(不及……)
举例:
1) Most doctors recognize that medicine is         .
A) an art as much it is a science           B) as much an art as it is a science
C) as an art as much it is science          D) much an art as it is a science
两者之间的比较:more… than结构:形容词或副词的比较级 + than;否定形式:less… than/原句中形容词或副词的反义词的比较级 + than。
形容词和副词的比较级前面可用much, rather, still, even, (by) far, yet, hardly, no, a bit, a little, a good/great deal, a lot/lots, three times等程度副词来修饰。(注意:many不能用来修饰比较级)。more than 前面可用 no, scarcely, nothing, little, hardly, almost, nearly等副词来修饰。(hardly more than不够,不超过; almost more than, nearly more than 几乎超过;as much as 表示程度多达……;more than或more … than 表示“与其说…不如说…”,“宁愿…也不愿”)
举例:
1) The little man was        meter fifty high.
A) almost more than     B) hardly more than     C) nearly more than     D) as much as
2) Certain programs work better for some         for others.
A) and                  B) than                 C) as                   D) but
3) He likes doing some reading at home        to the cinema.
A) than to go           B) than going        C) more than going     D) rather than to go
4) Indeed, almost every scientist now finds it impossible to read all the works relevant to his own subject,         extensively outside of it.
A) much less to read   B) much more to read   C) much less reading   D) still more reading
三者以上的比较:the + 最高级 + in /of/among或 one + of + the + 形容词最高级 + 名词复数。最高级前面可以有副词修饰,如:much, by far, easily, nearly, almost, by no means, not really, next, the second/third, but one。如:
Light travel (the) fastest of all forms of matter.在所有物质中,光运动得最快。
倍数表示法:
1) 倍2) 数 + as + a./ad. + as
3) x times + 形容词/副词的比较级 + than
4) x times + the size (length, width, breadth, depth, value, level, velocity(速度,5) 速率) of /that …)
6) double/treble(三倍7) 的)/quadruple(四倍8) 的) + 名9) 词
10) increase/expend (be, go up, speed up, raise, rise) + by + 倍11) 数/数字百分比, by后表示的是净增加数。Decrease, reduce, drop, go down表示相反意义。
Increase/expend (be, go up, speed up, raise, rise) + to + 数字(一定的量)。
举例:
1) The boy students in this school are nearly       as the girl students to say they intend to get a college degree in business.
A) as likely twice     B) likely as twice    C) as twice likely     D) twice as likely
2) She didn’t regret paying 200 dollars for the bookcase. As a matter of fact, she would gladly have paid         for it.

4) Between 1974 and 1997, the number of overseas visitors expanded        27%.
A) by                  B) for                C) to                  D) in
the + 比较级 (+ 主语 + 谓语), the + 比较级 (+ 主语 + 谓语),表示“越……越……”。More of a 意为“胜过,超过”;as much of a 意为“称得上”;less of a 意为“算不上”
举例:
1) She is         a musician than her brother.
A) much of            B) much as            C) more of              D) more as
not more than意思为“不超过,不及”;no more than为“只不过,仅仅”。
more(less)…than为“与其说…,不如说…”。
当more后面接复数名词时,不可用much修饰,这时须用many或far等程度副词来修饰。如:
many more opportunities(或far more opportunities)
much more money (或far more money)

副词的辨析
altogether/all together
altogether为“完全”(=entirely)或“总的来说”(=on the whole)。如:

I’m somewhat tired of this book. 我有些厌倦这本书了。
2) early / soon

5) ever / once
ever虽可译为“曾经”,但其更准确的意思应该为“无论何时”“究竟”,主要用于非肯定句,以及形容词和副词最高级表示比较范围的句子中,目的在于加强语气。
once意为“曾经”“昔日”“有一次(回)”,相当于一个表示过去时间的状语(at one time in the past),因此多用于谓语是过去时的句子中。
Neither of them has ever read this book.(否定句,加强语气)
他们俩谁都没有(曾经)看过这本书。
There once lived a man who had two daughters. (昔日,有一个时候)
曾经有一个人,他有两个漂亮的姑娘。

They moved into a new house lately(或recently).他们最近搬进了新居。
7) later / latter

Later (on), Cary came to join us, too.后来,卡里也参加到我们中间来了。
He spent the latter half of his life in Oxford.他的后半生是在牛津度过的。
8) most / mostly / almost

这是我读过的最有意思的一本小说。
She is mostly out on Sundays.她星期日通常外出。
It was almost dark when they reached there.他们到那儿的时候,天差不多黑了。
9) not / no
not为副词,常用作谓语等的否定词;no为形容词,对名词进行修饰或限定。

We got no help from them.我们从他们那儿未得到帮助。
10) rather / fairly

用rather意为“反感”,fairly意为“赞许”。
This soup is fairly hot.这汤热乎乎的。
This soup is rather hot.这汤太烫了一点。
11) still / yet / already
still表示无变化的延续性;yet表示“尚”,与already相对,常用于否定句和疑问句;already为“已”,常用于肯定句。

12) so / too

13) so / such
        a(n) + 形 + 名      such a hot day
such    + 形+ 名(复数)      such hot days
           + 形 + 名(不可数)   such hot water
   如用so表示,可以说so hot a day,但不能说so hot days, so hot water。
14) very / much / very much
   very修饰形容词、副词,及充当形容词功能的现在分词和已完全转化成形容词的过去分词。
   I am very happy (pleased) to hear of your success.听说你成功了,我很高兴。
   much修饰V-ed(过去分词演变过来的形容词),以及词和副词和比较级。
   The journey takes much longer time when the roads are crowded.
   当道路拥挤时,那段路程要花的时候长得多。
   very much 修饰肯定句中的动词。

(1) 时间状语从句:
引导时间状语的连词:when, as, while, till, until, not until, before, after以及带有强烈色彩的whenever, ever since等;还有些名词词组:each time, every time, the first time, the time, the instant, the moment, the day,ever since;还有某些副词:directly, instantly, immediately。还有no sooner…than…, hardly(scarcely)… when…。
when / while / as
when可表示从句动作与主句动作同时发生,或先于主句动作。while仅表示从句的动作与主句同时发生,并且有延续的含义。as表示从句动作与主句动作相并发生,所以常常译为“边…边…”。when和as可指一段时间,也可指一点时间。while仅可指一段时间。while也可以用作并列连词,相当于whereas, 接一个表示对比的并列分句。while连接的此类句子放在句首,仍表示并列关系。如:
You like sports while I’d like to read. 你喜欢体育而我喜欢读书。
When they heard the news, they were much alarmed.
听到这个消息,他们十分惊恐。(从句动作先于主句动作)
While the child was playing with his toys, his parents were reading book.
孩子在玩玩具,他父母在看书。(指一段时间,主、从句动作同时发生)
They shouted slogans as they passed the square.
他们高呼着口号,通过广场。(指相并发生的动作)
before / after
before引导的从句通常表示主句动作发生在从句动作之前,如从句是过去时,主句一般要用过去完成时。after引导的从句表示主句动作发生在从句动作之后,如主句是过去时,从句要用过去完成时。但如果表示的是连续动作,则before和after表示的从句中也用一般过去时。如:
Lenin had never heard English spoken before he went to London.
列宁去英国以前,从来没有听见过别人讲英语。
After they had finished their work, they went home.
他们干完了工作以后回家了。
as soon as / directly / immediately / once
都表示从句动作一发生,主句动作随即就发生,译为“一…就”。另hardly(scarcely)…when和no sooner…than也表示“一…就”。如:
As soon as we got home, it began to rain.
我们一到家,天就下雨了。
Directly I had done it, I knew I had made a mistake.
我刚做完这事,就知道我做错了。
Once a beginning is made, the work is half done.
工作一旦开始,便可说完成一半了。
till / until
两者都表示“直到…”,但句首只能用until。如:
I waited till (until) he arrived. 我一直等到他来。
the moment/ each time/ the minute/ the instant/ the year等
一些表示时间的名词词组如:the moment, each time, every time, next time, by the time, the first time, the minute, the instant, the year等常用于引导时间状语从句,这时它们起着连接词的功能。如:
Every time he came, he would bring us a lot of flowers. 
他每次来都要带给我们很多花。
举例:
1) I had just started back for the house to change my clothes       I heard voices.
as                    B) when                C) after                 D) while
解析:when在这里相当于just at that time,用作并列连词。when作连词的用法常常出现在以下结构中:be doing something when…
        be about to do something when…
        had hardly/almost done something when…
2) A man escaped from the prison last night. It was a long time       the guards discovered what had happened.
A) before                B) until               C) since                 D) when
解析:本句用了It is/was … (time) before …句型。
3) No sooner had we reached the top of the hill       we all sate down to rest.
A) when                  B) then                C) than                  D) until
地点状语从句:
引出地点状语从句的连词有:where, everywhere, anywhere, wherever。如:
Where there is oppression, there is opposition.哪里有压迫,哪儿就有反抗。
Sit wherever you like.你喜欢坐在哪里就坐在哪里。
Everywhere they went, they were warmly received.他们所到之处都受到热烈的欢迎。
举例:
1) I have kept that portrait        I can see it every day, as it always reminds me of my university days in London.
A) which                 B) where               C) whether                 D) when
原因状语从句:
由下列的连词引导:because, as, since。now that 既然;in that因为;seeing (that) 看到;considering (that)考虑到;for the reason that因为; on the ground(s) that所持理由是……。not that…, but that… 不是因为……,而是因为……。Because表示原因的语气最强,通常用于以疑问词“why”引导的疑问句。所以由because引导的从句一般置于主句的后面,表示主句谓语动词的直接原因;由as引导的从句可放在句首或句末;由since引导的从句通常放在句首,常表示已为人们所知的原因或理由。在it引导的强调句中,如强调的是原因状语,一般要用“It is because(不用as和since) that”。如:
Now (that) you are ready, we’ll start working at once.
既然你们都准备好了,我们马上开始工作。
Seeing that this problem was settled, they proceeded to the next one.
鉴于这个问题已经解决,他们开始进行下一项。
Criticism and self-criticism is necessary in that it helps to correct our mistakes.
批评和自我批评是必要的,因为它有助于改正我们的缺点。

3) These two areas are similar       they both have a  high rainfall during this season.
A) to that               B) besides that        C) in that             D) except that
目的状语从句:
目的状语从句以下连词引导:that, so that, in order that(以便),lest(免得), in case(以免)。
so that/ in order that
两者均表示“为了,以便”。在现在时的从句中,谓语动词常为may, can或will;在过去时的从句中,一般用could或should;might含义比较正式;有时也可用would。引出目的状语从句时,so that最常见,in order that常用于正式文体。另外,in order that引起的从句可位于主句前面或后面,so that引起的从句只可位主句之后。如:
Work hard so that you can (may) succeed.好好干以便你能获得成功。
He cam in quietly in order that he shouldn’t wake up his wife. (=In order that he shouldn’t wake up his wife, he came in quietly.) 他轻轻地进了屋,以便不吵醒他妻子。
in case/ lest/ for fear that
表示“以防”、“以免”。可用虚拟语气,形式为should + V原。如不用虚拟语气,要用一般现在时或一般过去时。如:
Batteries must be kept in dry places in case (=lest, for fear that) electricity should leak(或leaks) away.
电池应放在干燥的地方,以防漏电。
举例:
1) I was advised to arrange for insurance      I needed medical treatment.

2) The mad man was put in the soft-padded cell lest he        himself.
A) injure                 B) had injured         C) injured            D) would injure
结果状语从句:
结果状语从句由so… that或such…that引导。
1) so… that / such…that
都可引导结果状语从句,不同的是so后面须接形容词或副词,such后可接名词也可单独作表语,表示由此程度而导致某种结果。如:
The professor speaks so fast that we find it difficult to follow him.
这位教授讲话如此之快,我们感到很难理解他的意思。
He gave me such good advice that I finished the task easily.
他给我的建议非常之好,我很顺利地完成了任务。
The film was such that everyone was deeply moved.
这个电影那么精彩,观众都被深深地打动了。
2) so that / that / so
so that比较常用;so和that多见于口语。
so that引起的从句是表示结果还是表示目的的,除了根据上下文以外,还可从形式上来加以判断。so that引起结果状语时,该从句前面常常有逗号。so that引起目的状语时,该从句中常用may (might), can (could), should和would等情态动词。如:
He went early, so that he got a good seat.
他走得很早,所以搞到了一个好座位。(结果)
He went early so that he could get a good seat.
他走得很早,以便搞到一个好座位。(目的)
条件状语从句:
由下列关联词引导:if, unless(除非),assuming (that)(假定),on condition (that)(条件是),providing/provided(that)(假若), so/as long as(只要), as/so far(至于), suppose/supposing that(假使) ,granted/granted that(假定)
3) if / unless
unless在意义上等于“if…not”,且语气较强。If可用于虚拟语气,而unless不行。如:
You will make progress if you study hard.如果你努力学习,你就会取得进步。
You will never make progress unless you study hard.
除非你努力学习,否则是不会取得进步的。
4) as (so) long as / on condition (that) / providing (that) / in case
suppose/supposing仅用于问句中,也可引导一个虚拟条件句,语气委婉。
in case 引导的条件从句往往置于句首,目的从句多放在句子后面。也可使用should + V原的虚拟语气。
on condition (that)引出的条件句语气较重。
in the event (that)表示“如果”,基本上与if同义,但一般只用于真实条件句。
as (so) long as 和if only表达的语气比if要重,常译作“只要”。如:
As (So) long as you try, you will succeed.只要你尝试,你就会成功。
I will lend you this book on condition that (=only if) you return it to me before Friday.
我可以把这本书借给你,条件是你能在星期五以前还给我。
Motors will run well provided/providing (that) (=only if) they are maintained regularly.
只要定期保养,电动机就会运转良好。
I case he arrives before I get back, please ask him to wait.
如果他在我回来以前到来,请让他等一下。
Suppose/Supposing (that) it rains tomorrow,  will you still come?
假如明天下雨,你还来吗?
5) only if 和if only的区别:
only if(只要…)是if的强调形式,引导使用陈述语气的真实条件句,用倒装语序。
if only(有时作if…only…)大多用于虚拟语气,引导虚拟条件句和虚拟感叹句。如:
Only if you study hard, will you pass the test.
只要你努力学习,就会通过考试。(引导真实条件句)
If only we had arrived in time, we would not have missed the train.
要是我们按时到,就不会误车了。(引导虚拟条件句)
as (so) long as和as (so ) far as的区别:
前者是引导条件状语从句的连接词组,而后者是习惯用语“就…而论”的意思。
You may borrow the book so (as) long as you kept it clean.
只要你保持书的清洁,你可以借这本书。
As (So) far as I know, he hasn’t much money.就我所知,他没有多少钱。
举例:
1) I’m sure he is up to the job        he would give his mind to it.
A) if only                B) in case             C) until             D) unless
2)          he works hard, I don’t mind when he finished the experiment.
A) As soon as             B) As well as          C) So far as         D) So long as
3) We’ll visit Europe next year        we have enough money.
A) lest                   B) until               C) unless            D) provided
让步状语从句:
关联词为:although, though, whereas(鉴于), considering (that) (就…而论), much as(虽然很…);带有强调语气的:even though, even if(即便),以及带ever的疑问词和no matter+ 疑问词等,as和though还经常采用倒装方式引出让步状语,no matter+疑问词引出的让步状语从句等于带ever的疑问词引出的从句。
6) though / although / even if/ even though
都作“尽管”、“虽然”解。但even if 和even though所表示的让步语气最强,although次之,though最弱。如:
He is unhappy though (=although) he has a lot of money.
虽然他很有钱,可是他不幸福。
Atoms can be weighed even though (even if) we can not seen them.
虽然我们看不到原子,但是能算出它们的重量。
7) whatever (whenever…) / no matter what (when…)
常译成“无论…”,“不管…”。如:
Whatever (= No matter what) may happen (或happens), we will not change our plan.
无论发生什么事,我们决不改变计划。
No matter where you go (或may go), I will be with you.
无论你到哪里,我都要和你在一起。
举例:
1) I’ve already told you that I’m going to buy, it         .
A) however much it costs                 B) however does it costs much
C) how much does it cost                 D) no matter how it costs
方式状语从句:
可由连词as引导,从句一般置于句后,当方式状语由(in) the way (that), the way in which, (in) the same way, (in) the same way as, according as(视…情况而定), rather than等词语引导时,可表示比较,方式状语从句在be, act, appear, behave, feel, look, seem, smell, sound, taste等连系动词后由连词as if或as though引导时,从句表示的意思可以是真实的,也可以是不真实的,如果表示不真实,则用过去时表示现在不真实,用过去完成时表示过去不真实。
8) as如同,9) 就像
as引导的状语从句时,意思是“in the same manner that…”,可修饰动词或状态。如:
Study as Lenin studied.像列宁那样学习。
Air is to man as water is to fish.空气对如人,犹如水对鱼一样。
10) as if / as though
都是为“好像”,“仿佛”。它们引出的状语从句中,谓语动词常用虚拟语气,表示与事实相反。as if比as though更常用。如:
He speaks English as if (=as though) he were an Englishman.
他说起英语来好像是英国人。
The patient looks as though she had recovered.这个病人看起来好像已经痊愈了。
比较状语从句
由下列连词引导:as…as(像…一样),than(比), not so (so)…as(不像…一样),the…the…(愈…愈), as…so…(正如…那样)。如:
He worked as fast as a skilled worker.(上册P511)
他干得像熟练工人一样地快。
The project was completed earlier than we had expected.(上册P511)
这项工作完成得比我们预计的要早。
举例:
1) Melted iron is poured into the mixer much      tea is poured into a cup from a teapot.
A) in the same way like                   B) in the same way which
C) in the same way                        D) in the same way as

定语从句
定语从句,又称关系从句,在句子中起定语作用,修饰一个名词或代词,有时也可修饰一个句子。定语从句由关系代词或关系副词引导。关系代词主要有:who, whom, which, that, whose, as, but和than等;关系副词有:when, where, why和as等。
 
关系代词  who 代替人;作从句的主语;可引导限制性或非限制性定语从句   
  whom 代替人;作从句的宾语;可引导限制性或非限制性定语从句   
  which 代替物;作从句的主语、宾语;可引导限制性或非限制性定语从句   
  that 代替人或物;作从句的主语、宾语或表语;可引导限制性定语从句   
  whose 代替人或物;先行词的所有格形式,作定语;可引导限制性定语从句   
  as 代替物;常与same, such等连用,引导限制性定语从句;单独使用,引导非限制性定语从句;作主语,宾语或宾补   
  but 代替人或物;作主语从句;表示否定意义   
  than 有比较意义;修饰带有形容词比较级的名词   
关系副词  when 先行词是表示时间的词;作时间状语   
  where 先行词是表示地点的词;作地点状语   
  why 先行词是reason;作原因状语   
  as 先行词是作状语的词组;作方式状语 

关系代词的功能及其在定语从句中的作用
 
       代替功能
在从句中的作用 代替人 代替物 代替人或物   
主语 who which That   
宾语 whom which That   
定语 whose(=of which) whose(=of which)  

介词 + 关系代词其实是介词 + which/whom/whose这三种形式的概括。which的先行词为表示事物的名词,whom的先行词指人,whose在从句中作定语,限制其后的名词。细分为:
1) 介词 + which/whom
2) 介词 + which/whom/whose + 名3) 词
4) 名5) 词/代词/形容词的比较级或最高级/数词 + 介词 + which/whom
举例:
1) It is useful to be able to predict the extent        which a price change will affect supply and demand.
A) form                 B) with             C) to                 D) for
2) The residents,      had been damaged by the fire, were given help by the Red Cross.
A) all of their homes   B) all their home   C) whose all home     D) all of whose homes
3) The goals          he had fought all his life no longer seemed important to him.
A) after which          B) for which        C) with which         D) at which
4) Language is a city, to the building of       every human being brought a stone.
A) which               B) that              C) it                 D) this
as 引导的定语从句有“如……那样”的含义,它可以限制性的,多与such, so, as, the same等词连用构成such…as;the same …as可代替先行词是人或物的名词。在the same… as中,as也可以用that来代替。如:
Let’s discuss only such questions as concern us!
让我们只讨论与我们有关的问题吧!
This is the same watch as (或that) I have lost.
这块表和我丢失的那块一样。
as也可以引导非限制性的定语从句,可位于句首、句中、句末。通常由逗号将其与主句隔开。如:
He is an Englishman, as (=which) I know from his accent.
他是一个英国人,正如我从他的口音上知道的那样。
As was usual with him, he went out for a walk after dinner.
像往常那样,他吃完饭后出去散步了。
举例:
1) It wasn’t such a good dinner        she had promised us.
A) that                B) which             C) as                 D) what
          might be expected, the response to the question was very mixed.

The British are not so familiar with different cultures and other ways of doing things,
         is often the case in other countries.
A) as                  B) what              C) so                 D) that
先行词that 的用法:
6) 先行词是all, everything, something, nothing, anything, little, much, a few, one, none等不7) 定代词;如:
I am interested in all that you have told me.你告诉我的一切我都感兴趣。
8) 先行词形容词最高级修饰;如:
He asked for the best book that there was on the subject. 
他要有关这个内容的最好的书。
9) 先行词被序数词及first, last, no, every, only, few, much, some, any, the only, the very, what little(“一点点”)等词修饰;
This is the first (second, third…) time that…句型中,that从句中要求用完成时态。如:
This was the first time that I had seen the film. 这是我第一次看那部电影。
10) 并列的先行词分别表示人和物;如:
We were deeply impressed by the teachers and schools that we had visited there.
我们在那儿访问过的老师和学校给我们留下了深刻的印象。
11) 主句以who或which开头的特殊疑问句;如:
Who is the boy that(或whom) you were talking with a moment ago?
刚才和你谈话的那个男孩是谁?
12) 关系代词在从句中作表语;如:
This is not an easy question that you think it to be.
这个问题不是像你认为的那么容易。
13) 定语从句为there be句型,14) 此时that常可省略。
举例:
1) These people once had fame and fortune; now       is left to them is utter poverty.
A) all that            B) all what          C) all which          D) that all
2) All         is a continuous supply of the basic necessities of life.
A) what is needed      B) for our needs     C) the thing needed   D) that is needed

名词从句
主语从句
主语从句可以直接放在主语位置上,也可以用it作形式主语,而将从句放在谓语的后面。
即从句在复合句中做主语。引导词通常有that, 选择连词whether… or  (not), 疑问副词why, when, where和疑问代词who, what, which等。
[注:]whether (or not) 可引导所有名词从句;if仅可引导宾语从句,而且不可跟or not。
       当what引导的主语从句表示“…的东西”时,一般不用it作形式主语。如:
     What he want is a book.(对)
          It is a book what he wants.(错)
     他要的东西是一本书。
    如果带主语从句的句子是疑问式,则必须用it作形式主语的结构。如:
     Has it been settled who will be sent to carry out the task?
     谁将被派去执行这个任务决定了吗?
用it作形式主语的主语从句的固定用法:
It is + 名词词组 + 从句
It is a fact that…         事实是…
It is good new that…        …是好消息
It is a question that…       …是个问题
It is common knowledge that…    …是常识
It is + 形容词 + 从句
It is necessary that…        有必要…
It is clear that…          很清楚…
It is (un)likely that…        很(不太)清楚…
It is important that…        重要的是…
It is + 过去分词 + 从句
It is said that…          据说…
It is reported that…        据报道…
It has been proved that…      已证明…
It must be pointed out that…    必须指出…
It + 不及物动词 + 从句
It seems that…           好像是…
It happened that…          碰巧…
It follows that…           由此可见…
It has turned out that…       结果是…
举例:
1)          men have learned much from the behaviour of animals is hardly new.
A) That                B) Those             C) What              D) Whether
2) In some countries,         is called “equality” does not really mean equal rights for all people.
A) which               B) what              C) that              D) one
宾语从句
从句在复合句中充当宾语成分。引导词通常有that, what, whatever, whoever, whichever等。
常跟that引导的宾语从句的动词有:
admit(承认)  agree(同意)  answer(回答) believe(相信) command(命令)
complain(抱怨)confess(供认) decide(决定) declare(宣布)  demand(要求)
deny(否认)  doubt(怀疑)  dream(梦想)  expect(期望)  explain(解释)
feel(认为)  hear(听说)   hope(希望)  imagine(想象)  intend(打算)
insist(坚持) know(知道)   mean(意指)  notice(注意到)  prefer(宁愿)
order(命令) propose(提议)  reply(回答) report(报告)   request(请求)
require(要求) say(说)    see(看到)  suggest(建议)  suppose(假如)
think(认为)  urge(激励)   wish(希望) understand(明白)
常跟疑问代词和疑问副词以及whether (if)引导的宾语从句的动词有:
advise(忠告)  ask(询问)   discover(发现) discuss(讨论) doubt(怀疑)
find out(查明) imagine(想象) inquire(询问)  know(知道) question(询问)
show(展示)   tell(告诉)  understand(明白) wonder(想知道)
that引导的宾语从句,除可和介词in, except, but, besides等构成固定用法外,不能用作其他介词的宾语。but that(若不是…), in that(在于,因为), except that(除了…), besides that(除…以外)。如:
Men differ from brutes in that they can speak and think.
(在于…这一点)人和兽类的区别在于他们有语言和思想。
The meal was very good except that the fish was a bit too salty.
(除了…这一点)除了鱼有点太咸,这顿饭还是很好的。
I would have helped you but that I was so busy then.
(若不是…)若不是工作忙,我本来是会帮助你的。
举例:
1)By success I don’t mean         usually thought of when that word is used.
A) what is            B) that we            C) as you            D) all is
解析:经分析可看出主句中动词mean缺少宾语,则空格处应填入词语来引导一个宾语从句。从句中的动词thought of 缺少主语,只有what一词既能引导从句又能在句中充当主语。
同位语从句
同位语从句一般由that引导。常以that从句作同位语的名词有:fact(事实), evidence(证据), signs, idea(想法), plan, news(消息), belief, decision, opinion, truth, wish, possibility, conclusion(结论), order(命令), problem(问题), suggestion(建议), certainty(确实的事), hope(希望)等。
举例:
1)The mere fact        that most people believe unclear war would be madness does not mean that is will not occur.
A) what               B) which               C) that            D) why
2)         evidence that language-acquiring ability must be stimulated.
A) It is              B) There be            C) It being        D) There being
3) Evidence came up          specific speech sounds are recognized by babies as young as 6 months old.
A) what               B) which               C) that            D) whose

过去时
过去时包含两种时态:一般过去时和过去完成时。两者的区别:两者都表示过去的动作,但是一般过去时表示的是相对于现在的过去时间,而过去完成时表示的是相对于过去某一时刻的过去,即过去的过去。
一般过去时表示过去的确定时间里存在的状态或发生的动作,也可以表示过去经常发生或习惯性的动作,常与表示运去的时间状语连用,如:then, at that time, just now, yesterday, last week, three years ago, three days ago, in 1987等。如:
She often came to help me at that time.那时他常来帮助我。
过去完成时的时间概念是“过去之过去”,即表示过去的某一动作或状态在过去某一时间之前已经完成或存在,或者表示过去某个时间开始一直延续到过去另一个时间的动作。谓语形式:由had + 过去分词构成。表示在过去某一时刻以前已经完成的动作,常用一个由by, before等介词或连词引导的、表示到过去某一时间为止的时间状语。这一时态,常用于宾语或定语从句中。如:
When I came to her room, she had already left.
当我来到她房间时,她已经离开那里了。
By the end of last years, I had worked in this college for ten years.
到去年年底为止,我在这所学院工作已有十年了。
John had learned some Chinese before he came to China.
约翰来中国以前,学过一些汉语。
过去完成时也常用在“no sooner… than”,和“hardly… when (before)”等句型中的主句中,从句中常用一般过去时。“no sooner”“hardly (scarcely)”移至句首表示强调时,要求用倒装语序。
如:He had hardly entered the office when (before) the phone rang.
Hardly had he entered the office when (before) the phone rang.
他一进办公室,电话铃就响了。
举例:
1) Before the first non-stop flight made in 1949, it        necessary for all planes to land for refueling.
A) would be         B) has been               C) had been          D) would have been.
2) Until then, his family          from him for six months.
A) didn’t hear     B) hasn’t been hearing   C) hasn’t heard     D) hadn’t heard
3) The last half of the nineteenth century         the steady improvement in the means of travel.
A) has witnessed    B) was witnessed          C) witnessed         D) is witnessed
4) That tree looked as if it           for a long time.
A) hasn’t watered  B) didn’t water       C) hadn’t been watered D) wasn’t watered
解析:as if/ as though引导的从句,如果表述的并非实际情况就用虚拟语气;当表述的内容接近实际情况时则用陈术语气,在这种情况下主句的谓语动词是look/sound/taste/smell/seem等。
现在时
现在时包括一般现在时、现在进行时、现在完成时和现在完成进行时。
一般现在时:
1. 表示习惯性或反复2. 发生的动作,3. 常与它连用的时间状语有:now, at present, always, usually, often, seldom, these days,4. sometimes, every day, once a week等。如:He takes a walk after supper every day. (他每天晚饭后散步。)
5. 表示客观事实或普遍真理。如:The sun rises in the east and sets in the west. (日出东方,6. 日落西方。)
7. 在时间或条件状语从句中表示将来的动作,8. 代替一般将来时。如:If it is fine tomorrows, we will go on a picnic. (如果明天是晴天,9. 我们将去野餐。)
10. 与某些具有“出发,11. 到达”等含义的动词连用,12. 表示按计划将要发生的动作。如:The delegation arrives in Beijing this afternoon.(表团将于今天下午到达。)
13. 表示主语的特征、性格、能力等。如:Mr. Smith hates fish and never eats any. (史密斯先生讨厌鱼,而14. 且从不15. 吃鱼。)
现在进行时常表现正在进行或现阶段正在发生的动作,或表示一个按计划即将发生的动作。但仅适用少数动词而且常跟有一个时间状语。常见的这类动词有:go, come, leave, arrive等。
如:He is coming here next week and is staying here until August. 他将在下星期到这儿来,并且一直待到八月。
有些表示感觉、情感、心理状态、所有关系以及特征等状态动词不用于(或在某个词义上)不用于进行时,如agree(同意), belong(属于), have(有), love(爱), remember(记得), want(想要), appear(好像), see(看见), hear(听见), notice(注意), seem(好像), be(是), feel(感觉), know(知道), mind(介意), think(认为), believe(相信), forget(忘记),like(喜欢), realize(认识到), wise(希望)look, sound(听起来), remain, hate等。当这些词转为其他意思使用时,有的就可以用于进行时态了。
现在完成时强调的是某个刚刚完成的动作,或某个动作对现在的影响或产生的结果。常连用的时间状语:so far, up to now, already, just, recently, for three years, since last year, in the past three years, yet, never, before, ever, once等。
注意:
1)It is (has been)… since 这一结构也常用于现在完成时。如:
It is (=has been) a long time since they last met each other.
自有从他们上次见面以来,已有很长时间了。
2)This is the first (second) time that… 句型中,从句中常用完成时态。如:
This is the second time that I have broken a cup this year.这是我今年第二次打坏茶杯了。
Is this the first time that you have visited Hong Kong?这是你第一次参观香港吗?
3)在when和where引导的疑问中,一般不用现在完成时(“Where have you been?”
除外),因为这类句子询问的要点就是事情发生的具体时间和场合。
如:----When did you see him? 你什么时间看到他的?
----I saw him an hour ago.我是一小时以前看到他的。
----Where did you buy the book?你在哪儿买的这本书?
----I bought the book at our school book store.在学校书店买的。
      4)含有界限意义的动词,如:begin end, die, lose, find, fall, go,come, join等,以及含有瞬间意义的动词,如:knock, jump, strike, hit等,不能用于完成时的第二种用法。
    如:不可说:He has joined the army for ten years.
应该说:He has been an armyman for ten years.
或者说:It is (has been) ten years since he joined the army.
或者说:He joined the army ten years ago.他参军已经有十年了。
现在完成进行时则强调动作的延续性和延续的时间。表示过从过去某一时间开始一直延续到现在的动作,这个动作可能刚刚结束,或者可能要继续进行下去。通常与表示一段时间的状语连用,如:for hours, since this morning…。如:
They have been watching television for two hours. 他们已经看了两个小时的电视了。
举例:
1) If she doesn’t tell him the truth now, he’ll simply keep on asking her until she       .
A) does             B) has done            C) will              D) would do
解析:若主句用将来时,则从句用一般现在时表示将来时。
将来时
一般将来时表示将要发生的动作或存在的状态,多与表示将来的时间状语连用,如:tomorrow, next month, next week, in two weeks, soon等。
除shall, will+动词原形构成一般将来时,还有以下表示将来时间的其他形式:
1) be going to do 表示最近打算要做的事情
如:We are going to visit the Museum of Chinese History tomorrow. 
我们明天要参观中国历史博物馆。
2) be to do 表示按计划要发生的事情
如:There is to be a sports meet on Saturday.星期六要举行运动会。
3) be about to do 表示“即将(正要)做某事”
如:We are about to leave, so there is no time to visit her now.
我们要走了,所以没有时间去看她。
将来完成时表示某一动作在将来某一时间之前已完成,也多与一些表示将来的时间状语连用,特别是由by所组成的短语,表示截止到将来某一时间,如:by the end of this years, by then, by the time…等。但一般将来时不和这类状语连用。
如:I’ll have done all the work by the time you are back this evening. 
你们今晚回时候我就将做完全部工作。
举例:
1) By the end of this month, we surely         a satisfactory solution to the problem.
A) have found         B) will be finding      C) will have found       D) are finding
2) Turn on the television or open a magazine and you        advertisements showing happy, balanced families.
A) are often seeing   B) often see           C) will often see        D) have often seen
解析:用“祈使句 + and + 单句”的结构中,祈使句部分相当于由“if”引导的时态为一般现在时从句,根据时态呼应的原则,此时从句中的一般现在时表示的是将来时,因而主句中的谓语动词应该相应的使用一般将来时。 (注意:祈使句后面的由and或or连接的并列句常用一般将来时。)
3)  The conference        a full week by the time it ends. 
A) must have lasted   B) will have lasted     C) would last         D) has lasted
--“May I speak to your manager Mr. Williams at five o’clock tonight?”
--“I’m sorry. Mr. Williams        to a conference long before then.”
A) will have gone     B) had gone             C) would have gone    D) has gone

4、含情态动词的被动语态结构,形式为:情态动词(can, may, must) + be + 及物动词的过去分词,如:

   The problem is going to be discussed at the meeting.那个问题将在会上讨论。
7、如主动句中的宾补是不带to的不定式,当句子变成被动态以后,作为主补的不定式则应加上to。如:
   The manager made his secretary work overtime.(主动)
   经理迫使他的秘书加班加点。
   The secretary was made to work overtime. (被动)

8、有些动词虽然是及物的,但是由于表示的是状态或关系,通常不用于被动语态。如:cost(花费), fit(适合), have(有), hold(容纳), lack(缺乏), last(持续), own(占有), possess(拥有), resemble(像), suit(适合)。如:
   The boy resembles his father.这男孩像他的爸爸。
不可以说成:His father is resembled by the boy.
9、有少数短语动词如:be taken in (受骗,上当), be supposed to do something(应该,被期望), be intended for something(somebody)/to do something(旨在,用于),通常只用被动语态。如:
