Question

The number of people invited ______ fifty, but a number of them ______ absent(缺席) for different reasons.

A．were; was

B．was; was

C．was; were

D．were; were

Answer 1

C

試題分析：句意：受到邀請的人數(shù)是五十，但是很多人因為各種各樣的原因而缺席。The number of表示“的數(shù)量”，其主語為數(shù)目，所以后面的謂語動詞用單數(shù)形式，而a number of them表示“大量，許多”，后面修飾可數(shù)名詞的復數(shù)，后面的謂語動詞也用復數(shù)形式；故選C。
