1、时间 状 语 从 句 考 点 (一) 时间状语从句 当时候：It was six oclock when I got home. Sb was doing sth when1)when 这时 Sb was about to do sth/was on the point of doing sth when Sb had just done sth when 当时候(引导持续性动作): He fell asleep while he was reading a book. 2) while 然而(用于句中) : He likes pop music while I am fond of folk
2、 music. 虽然,尽管(用于句首) While volleyball is her main focus, shes also great at basketball. 3) before 在之前,.才 We had sailed four days before we saw land. 还没来得及 Before I could get in a word, he had measured me. It was +时间段+before sb did sth 过了（时间） It will be+时间段+before sb does sth 要过（时间）才It was two weeks b
3、efore we met again.两周之后我们才见面。 It will be two weeks before we meet again. 我们再过两个周才能见面。4) 几个极易混淆的时间状语从句：It was +时间点+when（当.的时候时间是.）It was 5 am when we arrived at the village.He left my room whilewhen I was reading a book.It was/will be+时间段+before(过了才要过才)It was/will be two weeks before we met/meet again.It is /has been +时间段+since（自从以来有）It is/has been 3 years since we last met.突破点：一看be动词的时态，二看时间段还是时间点。
