题目内容
15.I'll go shopping when I _____ this letter.( )| A. | finish | B. | finished | C. | will finish | D. | finishes |
分析 我写完这封信就去购物.
解答 答案:A
本句考查 when引导的时间状语从句的时态,在含有时间状语从句中的复合句中,如果主句中用了一般将来时,根据"主将从现"的原则,从句使用一般现在时表将来;一般现在时的构成是:主语+动词原形/动词的第三人称单数形式;主语为I故用动词原形. 故选A.
点评 本题考查了动词的时态.做题时,一定要特别关注有关的时间短语,这是判断句子时态的标志.在没有时间状语的情况下可以联系上下文根据语境来做出正确判断.
