There be 句型详解

这是一个固定句型,there be表示存在、有等含义,引出后续具体的名词成分。


There be句子整体其实是一个倒装结构,be.后面的名词才是句子的主语。

常见的完整there be句型如下:

There be + sth. + 地点/时间/状态.

其中地点/时间/状态可以存在一个或多个,也可以仅仅只是There be + sth.

There be句型可以和助动词、情态动词等结合使用。

  • There will be a holiday tomorrow.

如上所述,there be句型的主语是be之后的名词,所以系动词be的单复数由其后的名词决定:

1. 当动词be后所接的名词是单数可数名词或不可数名词时,be应该使用单数形式is

2. 当其后所接的名词是复数的可数名词时,be应该使用复数形式are


如果there be后跟多个并列名词,离there be最近的名词决定整体的单复数形式,即最近的名词决定be是使用is/was还是are/were

  • There are five books and a cup on the table.
  • There is a cup and five books on the table.

There be句型的一般疑问句形式是将be放在there之前,回答时用yesno,后接简单答语。

A: Is there a cup on the table?

B: Yes, there is. No, there isn't.

There be句型的特殊疑问句主要有以how manyhow much做引导词的两种情况:

  • How many students are there in your school?
  • How much money is there in your pocket?
  • There is a cup on the table, isn’t there?

非谓语形式的there to bethere being结构可用作主语、宾语、或状语等。
