存在句的非限定形式是there to be和there being結(jié)構(gòu)。這兩種結(jié)構(gòu)在用法上有相同點(diǎn)。為便于比較，我們把它們放在一起介紹。

1） 作介詞補(bǔ)足成分

兩種結(jié)構(gòu)都可作介詞補(bǔ)足成分。如果介詞是for，便只能用there to be結(jié)構(gòu)。

Eg.) It is too early for there to be anyone around here.

It is important for there to be a fire escape.

也能用在不及物動(dòng)詞+for之后:

They planned for there to be another meeting.

如果介詞不是for, 則要用 there being結(jié)構(gòu)。

Eg.) John was relying on there being another opportunity.

----We didn’t find Smith attending the lecture.

----No one told him about there being a lecture the following day.

2） 作賓語(yǔ)

作賓語(yǔ)時(shí), 通常用there to be結(jié)構(gòu)。

Eg.) Members like there to be plenty of choices.

能這樣用的及物動(dòng)詞為數(shù)有限,常見(jiàn)的有expect, mean, intend, want, like, prefer, hate等。

3） 作主語(yǔ)和狀語(yǔ)

there being結(jié)構(gòu)還能用作主語(yǔ)和狀語(yǔ)。

Eg.) There being a bus stop so near the house is a great advantage.

There having been no rain, the ground was dry.

存在句的限定形式與非限定形式之間可以相互轉(zhuǎn)換。

For there to be so few people in the streets was unusual.

(=It was unusual for there to be so few people in the streets.)

有時(shí)限定形式與非限定形式還可以結(jié)合使用。

Eg.) It is said that there are troops on the frontier.

=There are said to be troops on the frontier.
