英语小知识,(a number of&the number of)
3个回答

◇a number of…意思是“一些,若干”(= some),后接可数名词复数或代词,谓语动词用复数形式.

a number of…词组中还可以加入形容词表示数量大或小等(例如:a large/small number of…许多/少数……).

◇the number of…意思是“……的数字/数目”,介词of同其后名词构成介词短语,修饰the number.当它作主语时,谓语动词用单数.

例如:

Many people took part in 10,000-metre race,but only a number of them kept on running to the end.许多人参加了10000米跑,但只有一些人坚持跑到底.

A number of my friends think I should take a holiday.
