例如:

Many a way has been tried.

6、pair of等表示數(shù)量的名詞短語修飾主語時(shí),謂語的形式要與pair等名詞形式一致。常見的有:pair of/kind of/type of/box of等。(但a lot of/lots of和a number of不屬于這一類)。

例如:

There is a pair of shoes left.

7、從句或短語(包括不定式和動(dòng)名詞)作主語時(shí),往往表達(dá)一種抽象概念,謂語動(dòng)詞用單數(shù)。

例如:

Waving hand is to say“goodbye”.

What he said is wrong.

8、maths/news/physics/the United States等單數(shù)概念,復(fù)數(shù)形式的名詞作主語時(shí),謂語動(dòng)詞多用單數(shù)。

例如:

The United States was founded in 1776.

9、時(shí)間、距離、金錢、重量、容量等名詞作主語時(shí),謂語動(dòng)詞用單數(shù)。

例如:

Twenty years is a long time.

Two hundred dollars is a lot of money.

10、the number of+名詞,謂語動(dòng)詞用單數(shù):a number of+名詞,謂語動(dòng)詞用復(fù)數(shù)。

二、賓語從句

1、連詞:連詞由充當(dāng)賓語從句的句子語氣來確定。如果為陳述語氣,則用that(可省略);如果為特殊疑問語氣,則用適當(dāng)?shù)奶厥庖蓡栐~;如果為一般疑問語氣,則用if/whether(是否)。

例如:

He says (that)he lives in Beijing.

I don′t know where he works.

Could you tell me if/whether it snows in winter in Australia?

注意:在賓語從句中,if后面不能直接跟or not,而whether后面則可以。
