He _____ to the lab than he set out to do the experiment A.has no sooner got B.no sooner got C.will no sooner get D.had no sooner got 答：D 译：他一到实验室就着手做起了实验。 析：no sooner .... than.... hardly ........ when... 主句用过去完成进，从句用一般过去时。 记忆方法：sooner是比较级，所以用than
他一到实验室就开始做实验。 no sooner than 一...就.... 引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 。
