as引导让步状语从句的倒装形式

as引导让步状语从句的倒装形式

as引导的这种让步状语从句语气比较强，语体正规，经常用于书面语言，意为“尽管，虽然”。从句需要进行倒装。

其倒装构成形式见下表。

■使用as引导让步状语从句时，还应注意以下几点：

1.这类让步状语从句一般应置于主句之前，但有时也可放在主句之后或插入到主句之中。

e.g. He would do it，forbidden as he was.

The book，masterpiece as it is，is far from popular.

2.这类让步状语从句中的as有时也可以换用成though；如果表语是名词时还可以用that来替代。

e.g. Disabled though（=as）he is，he tries his best to serve the people.

Lover of towns that（=as）I am，I realize that I own a great debt to my early country life.

Patient though（=as）he was，he was unwilling to wait three hours.

3.有时as表示原因时也可使用倒装结构，这时应注意as表示原因与表示让步的区别，其辨别方法主要是根据句子的意义。

e.g. Busy as she is，she cannot attend the meeting. （原因）

Busy as she is，she works hard at English. （让步）

Fast as he read，he finished the book in time. （原因）

Fast as he read，he could not finish the book in time. （让步）

4.注意下列几种说法，意义基本相同：

Rich as （though） he is，I do not envy him.

（Al）though he is rich，I do not envy him.

However rich he may be，I do not envy him.

No matter how rich he is，I do not envy him.

I do not envy him，even though he is rich.
