二、精典名題導(dǎo)解
選擇填空
1. ____________ people in the world are sending information by e-mail every day.
a.several million b.many millions
c.several millions d.many million
解析:答案為a。本題考查的是million表示確切數(shù)量的用法。million前需用數(shù)表確切數(shù)量 ,而不用many這類詞,但可說many millions of(上百萬的),故本題中用several million。
2. the number of people invited __________ fifty, but a number of them __________ absent for different reasons.
a.were ; was b.was ; was c. was ; were d.were ; were解析:答案為c。本題考查的是the number of + 名詞與a number of + 名詞作主語時謂語的單復(fù)數(shù)問題。the number of是“……的數(shù)目”,作主語時謂語動詞用單數(shù),而a number of 后接可數(shù)名詞的復(fù)數(shù)形式,作主語時謂語動詞用復(fù)數(shù)形式,故此題最佳選項為c。
3. shortly after the accident, two ___________ police were sent to the sport to keep order .
a.dozens of b.dozens c.dozen d.dozen of
解析:答案為c。此題考查的是數(shù)詞dozen表示確切數(shù)量時的用法,dozen表示確切數(shù)量時用其單數(shù)形式,當(dāng)dozens的復(fù)數(shù)后接of時則表示不確切數(shù)量,本題答案為c。
