there be用法归纳?

|2024-10-21 06:51:57|浏览:69

1. there be用于一般现在时

There be句型

这里的be是指is和are。there is用于可数名词的单数和不可数名词,there are用于可数名词的复数。

There is a book in my backpack.

我的背包里有一本书。

There is some water in the bottle.

瓶子里有些水。

There are many boys in the park.

公园里有很多男孩。

但是要注意,there be句型遵循就近一致原则,通俗的说就是,这里的be是用is还是are,主要取决于其后的第一个名词的单复数。如果该名词是单数,那就用is,哪怕后面还会有其他名词。如果该名词是复数,那就用are。请看例句:

There is an apple, three bananas and a piece of bread on the table.

桌子上有一个苹果、三根香蕉和一块面包。

上面这个例句中,there be后面第一个名词是an apple,为单数名词,因此这里的be就用is,不受后面three bananas and a piece of bread的影响。但如果把there be后面第一个名词换成three bananas,这里的be就应该用are,如下句:

There are three bananas, an apple and a piece of bread on the table.

桌子上有三根香蕉、一个苹果和一块面包。

2. there be用于一般过去时

There be的一般过去时为there was和there were。there was用于可数名词的单数和不可数名词,there were用于可数名词复数。

There were five famous musicians at the concert.

在这场音乐会上有5位著名的音乐家。

应当注意,there was和there were也遵循就近一致原则。

There was a guitarist, a violinist and three singers at the concert.

音乐会上有一位吉他手、小提琴手和三位歌唱家。

There were three singers, a guitarist and a violinist at the concert.

音乐会上有三位歌手、一位吉他手和一位小提琴手。

3. there be用于一般将来时

there用于一般将来时有两种表示方式,一种是there will be,可用于可数名词的单数和复数,以及不可数名词。另一种是there is / are going to be,there is going to be用于可数名词单数和不可数名词,there are going to be用于可数名词复数。
