状语从句练习30题1. I was doing my homework ______ my mother was cooking dinner.A. whileB. whenC. asD. until答案:A。
本题考查时间状语从句中“while”“when”“as”的用法区别。
“while”强调两个动作同时进行,“我做作业”和“妈妈做饭”两个动作同时发生,所以用“while”;“when”既可表示动作同时发生,也可表示一个动作在另一个动作发生的过程中发生;“as”通常强调两个动作伴随进行;“until”表示“直到……”,不符合题意。
2. We were having a picnic ______ it suddenly started to rain.A. beforeB. afterC. whenD. while答案:C。
“when”在此表示一个动作正在进行时,另一个动作突然发生,“正在野餐”时“突然开始下雨”;“before”表示“在……之前”;“after”表示“在……之后”;“while”强调两个动作同时进行,此处不合适。
3. ______ I was walking in the park, I saw a beautiful bird.A. WhileB. WhenC. As soon asD. Before答案:A。
