1.地點狀語從句考點聚焦

where, wherever

Make a mark wherever you have any questions.

We will go where the Party directs us.

2、目的狀語從句：that, so that, in order that

注意：目的狀語從句的謂語動詞常與情態(tài)動詞連用，否則可能是結(jié)果狀語從句。不可置于句首。

3、結(jié)果狀語從句：that, so that, so … that, such … that …

注意：so + 形容詞/副詞 + that從句；such +　名詞 + that從句。

4、方式狀語從句：as, as if(though)

I’ll do as I am told to.

It looks as if it is going to rain.

5、比較狀語從句：than, as

6、條件狀語從句：if, unless, so (as) long as, in case, once, a far as, on condition that.

注意if與unless的區(qū)別：不能用and連接兩個unless從句，即不能有… unless …,and unless … 。但if … not and if … not卻不受此限。

You won’t lose your weight unless you eat less and unless you exercise more.(×)

但可以說 … unless you eat less and exercise more.

7、注意狀語從句中從句的省略現(xiàn)象

（1）連接詞 + 過去分詞

Don’t speak until spoken to.

Pressure can be incrased when needed.

Unless repaired, the washing machine is no use.

（2）連詞 + 現(xiàn)在分詞

Look out while crossing the street.

（3）連詞 + 形容詞/其他

常見的有it necessary、if possible、when necessary、if any等。
