题型:不详难度:来源:
The bus ____ at six, but it arrived an hour later.A.should arrive | B.had arrived | C.should have arrived | D.must arrive |
|
答案
C |
解析
试题分析:考查情态动词用法。Should have done被应该做某事,实际上却未做;根据下句的arrived说明本句是对过去情况的虚拟,故使用“情态动词+have done”的形式;句意:公交车本应该在6点到,但是却晚来了一个小时。故C正确。 情态动词的用法比较复杂。突出的是表示推测:如果是对现在的情况进行推测,使用“情态动词+动词原形”;对过去的情况进行推测,使用“情态动词+have done”;情态动词也经常用于虚拟语气,要分具体情况来分析,在条件句中和宾语从句,表语从句中都有体现。 |
