题型:不详难度:来源:
I        my homework while my mother was reading a book last night.
A.didB.doC.was doingD.were doing

答案
C
解析

试题分析:句意:昨晚当我的母亲正在读书时,我正在做作业。While引导时间状语从句时,强调动作的同时发生,结合语境可知主句描述的是过去正在进行的动作,句子主语是I,故助动词用am的过去时态was,选C。
点评:英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型,首先要注意句子中的时间状语,如果没有则要通过分析上下文,结合语境来判断句子的时态。
