一、there be结构用法归纳

there be结构表示“有”,其确切含义是“存在”,表示“某地(时)有某物(人)”。如:

There is a desk in the bedroom. 卧室里有一张书桌。

There are seven days in a week. 一个星期有七天。

1. there be结构中的there 是引导词,没有实际意义,主语是be后的名词。其中be的形式随名词来确定:主语是单数或不可数名词时用is;主语是复数名词时用are。如:

There is a purse here. 这里有一个钱包。

There is some money in the purse. 钱包里有一些钱。

There are 48 students in Class Eight. 八班有48个学生。

2. there be结构中,不论作主语的名词有几个,be动词只与第一个名词保持数上的一致,这被称为“就近原则”。如:

There is a teacher and many students in the computer room. 电脑房里有一位老师和许多学生。

There are two cards and some money in the box. 箱子里有两张卡片和一些钱。

3. there be结构表示“某处有某物(人)”,强调存在,并不特指某物是谁的,因此作主语的名词前常用表示泛指的a, an, some, any, many, much, a lot of, a few, a little等词或数词修饰,而不用定冠词、物主代词、指示代詞来修饰。如:

There is a bag on the bed. It is hers.

4. there be结构中的时间和地点状语通常置于句末,但强调时间或地点时,也可置于句首。如:

On this floor there is a reading room. 在这层楼上有一个阅览室。(强调在这层楼上)

This afternoon there is an English class. 今天下午有一节英语课。(强调今天下午)

二、there be结构句子形式

1. there be结构的否定形式是在be后加上not,如果句中有some,要改为any。如:

There is a big library in our school. →There is not a big library in our school.

2. there be结构的一般疑问句形式是把be动词提到句首,即“Is there...?”或“Are there...?”,肯定答语用“Yes, there is / are”,否定答语用“No, there isnt / arent.”,如果句中有some,要改为any。如:

There are some girls behind the house. →Are there any girls behind the house? Yes, there are. / No, there arent.

3. there be结构的特殊疑问句形式是“疑问词+一般疑问句?”。

对主语提问通常用what,省去引导词there。即用句型“what is + 地点状语?”。如:

There are some books on the desk. →What is on the desk?

对数量提问用“How many+复数名词+are there +其他?” 对不可数名词前的数量提问用“How much+不可数名词+is there+其他?”如:

There is a tree in the garden.→How many trees are there in the garden?

There is some milk in the cup.→How much milk is there in the cup?

注意: has / have也表示“有”,在表示所属或部分关系时,可以和there be句型相互转换。如:

There is a big playground in our school.

→ Our school has a big playground.

但是,一定不能把have和there be两者混用。如:

误:There has a small park near my school.

正:There is a small park near my school.
