题目内容
3.He was reading yesterday's China Daily_________ he was wanted on the phone.( )| A. | as | B. | after | C. | while | D. | when |
分析 昨天有人打电话找他的时候,他正看中国日报.
解答 答案:D.这四个词都可以引导时间状语从句.as意思是"当…时"强调两个动作同时发生;after意思是"在…之后"强调两个动作有先后顺序发生;while意思是"当…时"只能表示段时间状语;when意思是"当…时",有"这时突然"的意思,经常用来表示一个动作发生在另一个动作过程当中.既可以表示点时间,也可以表示段时间.根据"He was reading yesterday's China Daily"以及"he was wanted on the phone"他昨天在看报纸的时候,这时突然有电话找他.可知有人给他打电话是发生在他看报纸这个过程当中,所以要用when,故选D.
点评 首先要掌握这四个连词的用法,特别是when的用法,然后结合具体的语句,就可以做出正确选择.
