英语中有两个相似的短语:a number of与the number of,二者的区别涉及到主谓一致的问题,它们修饰名词作主语时,谓语的数是不一样的。 ①number of +名词复数
=a lot of =los of+名词复数
②a 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。 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……)。
A number of students of our school have read that magazine.
我们学校有很多学生都看过那本杂志。
A number of wild animals have been found in the forest.
森林里发现了很多野生动物。
③the 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. 我的一些朋友认为我应该休假。
