There be 结构
1. There be 结构的完整形式是:There + be + 名词(主语) + 地点或时间状语。通常用来表示“在什么地方或什么时间存在什么人或事物”;
2. There be 结构的否定形式是在 be 后面加否定词 not 或 no,例如:
(肯定)There are some chairs in the room.
(否定)There are not any chairs in the room.
这里注意 some 和 any 的用法:some 用在肯定句中,而 any 用在否定句和疑问句中。
3. There be 结构的疑问句形式是把 be 动词提前,例如:
Are there any chairs in the room?
回答用 Yes 或 No,例如:
Yes, there are.
No, there aren’t.
4. There be 结构与 have 的区别:
there be 表示存在关系,例如:There are four plates on the table.
have 表示从属关系,例如:The table has four legs.
5. There be 结构中 there 本身没有意义,be 需要与主语的数保持一致。例如:
There’s a man at the door.
There are fabulous wildflowers in the hills.
6. 另外,be 动词还有不同时态的变化,也可以同助动词、情态动词连用,例如:
There were once a million people in the city.
There will be an English class in our company next Tuesday.
There hasn’t been any rain for months.
