Question

The number of students in our school        4000 and a number of them     good at playing ping pong.

A．is, is

B．a(chǎn)re, are

C．is, are

D．a(chǎn)re, is

Answer 1

C

試題分析：我們學(xué)校學(xué)生的數(shù)目是4000，他們中許多人擅長打乒乓球。結(jié)合語境可知前文number表示數(shù)字，故be動詞用單數(shù)。下文a number of them表達復(fù)數(shù)含義，故系動詞用復(fù)數(shù)。選C。
點評：number of表示……數(shù)目，是抽象含義，不可數(shù)；a number of許多，表達復(fù)數(shù)含義，謂語動詞用復(fù)數(shù)。熟記即可。
