复数

Steam and ice are different forms of water. 一些常用复数或只有复数形式的名词如arms，

stairs，goods等。

The goods are sold out. 以s结尾的专有名词如山脉、运动会、群岛等。

特

提

醒 由两部分构成的表示物体的名词，如trousers，pants，

jeans，compasses(圆规)，glasses，shorts等作主语时，

谓语动词常用复数形式。但如果这类名词前用了 a

pair of或two/three...pairs of来修饰，谓语动词在数上

要与pair保持一致。

例句

①Your glasses are very nice.

②This pair of glasses is mine.

③Here are some new pairs of shoes. "名词＋with，along with，together with，as well as，

rather than，as much as，but，except等＋名词"结构

作主语时，谓语动词的单复数形式要与第一个名词保持一致。

①Tom as well as two of his friends was invited to the party.

② Dr.Smith, together with his

wife, is to arrive on the

evening flight. a quantity of后既可接复数名词，亦可接不可数名词。

如果a quantity of接不可数名词，则谓语动词用单数

形式；如果接复数名词，则谓语动词通常要采用复数

形式(※偶尔谓语动词用单数，属非规范用法，宜慎

用)。quantities of后接复数名词、不可数名词，后面

的谓语动词都用复数形式。 ① There is a small quantity

of water left in the bottle.

② A large quantity of books

are on sale now.

③Great quantities of fish were caught that day. 若用and连接两个动名词、不定式短语或主语从句，

表示两个不同的概念则谓语动词用复数形式。若表示

同一概念，则谓语动词用单数形式 ① Riding on the elephants

and rowing the boats were the

children's favorite games.

①What he says and does do not agree.

②What he says and does does not concern me.
