表示不定的人或物的名词作动词be的主语时,通常用there+be+名词结构。可以说A policeman is at the door(门口站着一位警察),但通常说There is a policeman at the door(有一位警察站在门口)。
注意:虽然there像是主语,但真正的主语却是跟在动词之后的名词。如果该名词是复数,动词在数上就必须和它一致:
There are two policemen at the door.
有两个警察站在门口。
上述两种句子结构(即名词+be结构和there+be+名词结
构)都是可行的,当be意为exist(存在)/happen(发生)/takeplace(发生)时there结构是必要的:
There is a mistake/There are mistakes in this translation.
这篇译文里有错误。
这个句子不能改写成A mistake is/Mistakes are等。
在下列句子中,例句之后加(R)的表示there结构可被名词/代词+动词结构代替:
There have been several break-ins this year.
今年发生了好几起强行入室盗窃事件。
There will be plenty of room for everyone.
将有足够的房间分给大家。
There were hundreds of people on the beach.(R)
海滩上有成千上万的人。
there同样也可以与someone/anyone/no one/something等连用:
There’someone on the phone for you.(R)
有你的电话。
there+be+something/nothing/anything+形容词结构也是可以的:
-Is there anything wrong(with your car)?(R)
-No,there is nothing wrong with it.(R)
-(你的车)出了什么毛病吗?(Examda)
-不,没出什么毛病。
There’s something odd/strange about this letter.
这封信有点奇怪。
名词或someone/something等后面可跟关系从句:
There’s a film I want to see.
有部电影我想去看。
