在英文的运用中,the number of和a number of有混淆的现象;它们后面的动词和名词的数常会有问题。
在形式上,the number of 和a number of相差一点点,一个用定冠词 the;另一个用不定冠词 a.可是在语义和用法上,两者的差别就大了。稍微大意,就会犯了谓语动词和真正主语搭配不当的问题。
A number of的意思是若干或许多,相当于 some 或 a lot of,和复数名词连用。当它出现在主语前时,谓语动词和主语搭配。必要时,还可以加上形容词great, large, small, good 等。例如:
① A number of highly qualified scholars have worked in Singapore.
② A great number of junior college graduates opt for business administration courses.
③ There are a large number of teaching posts yet to be filled.
④ Only a small number of men want to be language teachers.
⑤ A good number of books in the market are examination-oriented.
The number of和a number of一样,跟在后头的名词也是复数的,不同的是这里的主语是单数的 the number,不是它后面的复数名词,谓语动词必须和 the number 呼应,如:
⑥ The number of undergraduates has increased over the years.
⑦ The number of new houses is unable to cope with the ever-growing population.
