真题演练
It was quite some time_____ the president managed to save his firm from near bankruptcy. (2005.46)
A. before B. that C. when D. until
答案:A。
本题考查before引导的状语从句。分析题目主干可以看出在It was quite some time中,It为主语,was为系动词,sometime表示时间长度,为表语,因此空格后的部分为状语,需添加介词before。

I can learn knowledge of plants every time I go to my grandfather’s garden.
