分析 -昨下午7:00钟的时候,你和你的妈妈正在干什么?
-我正在看电视,而妈妈在做家务.
解答 答案:C;when当…时候;as soon as一…就;while在…期间; 与…同时;when引导时间状语从句,(1)在一个动作发生的过程中,另一个动作发生;(2)在一个动作发生后,另一个动作紧接着发生;while引导时间状语从句,表示一个动作发生的同时,另一个动作也在发生(此时含有一种对比的意思),这时,前后的句子一般都是进行的时态,或动词都是延续性的状态动词.根据句中信息I was watching TV my mother was doing housework,可知该句表示动作同时发生,且前后都是持续性动作,表对比,用while;故选C.
