（七）让步状语从句

让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。

e.g. Though he is a child, he knows a lot.

Child as he is, he knows a lot.

Whatever ( = No matter what ) you say, I’ll never change my mind.

（八）方式状语从句

方式状语从句常由as, as if (though), the way, rather than等引导。

e.g. You must do the exercise as I show you.

He acted as if nothing had happened.

（九）比较状语从句

比较状语从句常用than, so (as) … as, the more … the more等引导。

e.g. I have made a lot more mistakes than you have.

He smokes cigarettes as expensive as he can afford.

The busier he is, the happier he feels.

（十）使用状语从句时要注意的几个问题

1、在时间和条件(有时也在方式、让步等)从句中，主句是一般将来时，从句通常用一般现在时表示将来。

e.g. We’ll go outing if it doesn’t rain tomorrow.

I’ll write to you as soon as I get to Shanghai.

2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致(或虽不一致，是it)，从句的谓语又包含动词be ，就可省略从句中的“主语 + be”部分。

e.g. When (he was) still a boy of ten, he had to work day and night.

If (you are) asked you may come in.

If (it is) necessary I’ll explain to you again.

3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。

e.g. You are to find it where you left it.(地点状语从句)

Tell me the address where he lives.(定语从句，句中有先行词)

I don’t know where he came from.(宾语从句)

Where he has gone is not known yet.(主语从句)

This place is where they once hid.(表语从句)
