题目内容
6.________ I got back,I found my mother cooking for me.( )| A. | When | B. | Before | C. | Since | D. | Although |
分析 当我回来的时候,我发现我的妈妈正在给我做饭.
解答 答案:A when意为"什么时间"引导时间状语从句;before意为"在…以前"引导时间状语从句;since意为"自从…以来"引导时间状语从句;although意为"即使"引导让步状语从句.根据"my mother cooking for me"可知当从句动作发生的时候,主句动作正在进行.所以要用when来引导时间状语从句,before,since不符合题意.故选A.
点评 首先要掌握when,before,since,although这几个连词的意思,然后结合具体的题意做出正确选择.
