主谓一致

一、语法一致:

即作主语的名词词组中心词和谓语动词要在单、复数形式上保持一致。需注意:each,every,either,one,
another另一个,neither以及由some,any,no,every构成的复合代词作主语时，谓语动词用单数形式。
例:Each takes a cup of tea.每人喝一杯茶‌
Nothing but trees was to be seen.所见到的只有树‌

二、意义一致:

主语和谓语动词的一致关系取决于主语的单、复数意义，而非取决于语法上的单、复数形式。如主语在语法形式上为单数，但有复数意义，随后的动词便用复数。
Every means is tried to solve the problem. (单复数同行,此处表单数意义)
The young are usually very active. (the young指一类指整体概念)
Fifty-six dollars was stolen from the cash register(谓语用复数)

三、特殊一致

(一)就近原则:谓语动词的单、复数形式决定于最靠近它的词语(主要指名词)的单、复数形式。主要包括:therebe句型，还有连词or, either...or..., neither...nor...,
not only...but also...,not...but...等连接的并列成分。
There is a teacher, three students in the classroom.教室里有一个老师，三个学生。
Either you or I am going to the movies.‌不是你就是我要去看电影‌。
Not only he but also his family members成员 are interested in football match比赛.‌不仅他本人，他的家人也都对这场足球比赛很感兴趣‌。
(二)就远原则:谓语动词的单、复数形式取决于离它较远的词语的情况。主要是指主语后面有with,together with(和……一起、连同),as well as(“和……一样好；不但……而且；以及”),
no less than(“不少于；不亚于”), along with(“和……一起；连同”), like,rather than(而不是), but, except(“除了……之外（不包含）”),including(“包括……在内”)，
in additionto(“除了……之外（还）”)等短语+名词时，谓语动词不受这些短语的影响，仍然与主语保持一致。
No one except my parents knows anything about it.除了我父母，没有人知道这件事。
The actress, along with her manager and some friends, is going to a party.这位女演员和她的经纪人以及一些朋友要去参加一个聚会。
例子1.The old man,together with his neighbors邻居,(C) the performance when it began to rain.
A.have enjoyed B. has enjoyed C. was enjoying D. were enjoying
