时间状语从句
【题目】
I had been looking for the book for two days ( ) I found it at last
A.until
B.when
C.before
D.while

A.No sooner it grew dark than
B. Scarcely had it grown dark when
C.Hardly did it grow dark that

【难度】基础
【答案】C
【解析】第一句话“我不知道他下周什么时候来”，when引导宾语从句，表示将来时，就用一般将来时will come；第二句话“当他来的时候，请让我知道”，when引导时间状语从句，用一般现在时表示将来时，所以用comes。
【题目】

A.know
B.will know
C.knows
D.knowing

A.the moment
B.the moment when
C.at the moment
D.at the moment when
【难度】中等
【答案】A
【解析】他说他一到家，就会给你打电话. 英语中表示时间的名词短语有the moment, the minute, the instant等，用于as soon as的意义时可以引导时间状语从句，这些词在句中起着连词作用，因此不再需要when等连词，因此排除B和D。At the moment是介词短语，在句子中作状语，不能引导时间状语从句，故选A。

A. As
