　　A. when     B. since    C. for      D. whereas

　　     2.地点状语从句


　　     Where  引导地点状语一般总是放在主句的后面。例如：

　　A driver should slower down where there are schools.



　　     3.原因状语从句



　　Since从……起；因为……

　　比较特殊的连词：in that因为的意思。例句：The girl is like her mother in that she also has very delicate feeling.

　　Now that…因为；given that…



　　4.    目的状语从句


　　lest… 唯恐，害怕;for fear当心，害怕引导的是虚拟语气。谓语是should +动词原形。should常省略。



　　5.结果状语从句   有两种引导法so…that;  so that;  such…that;  such that

　　So fast does light travel that it is difficult for us to imagine it’s speed.

　　to the extent (that)表示结果

　　to some extent 表示在……之内。在某种程度上



　　6.条件状语从句  用unless； if 引导

　　A. only if   B. much as   C .long before    D. ever since

　　重点：与as有关的让步状语从句

　　由as 引导的倒装句

　　adj.,adv.,分词，名词，短语+as+主语+谓语。

　　例如：Child as he is, he can remember a lot of things.

　　as 或so+adj+as+主谓结构

　　例如：As much as John hates to do it, he must stay at home and study tonight.



　　8.比较状语从句


　　重点讲倍数为题

　　1.倍数+比较级A is three times bigger than B.

　　2.倍数+as…as 结构。A is three times as big as B.

　　3.倍数+名词结构A is Three times the size of B.

　　No more than 特点：

　　2.从功能上看往往表示两个事物之间的类比关系。

　　3.从意义上看是和……一样。

　　Not so much as

　　结构上有两种1. Not A so much as B.
