关于让步倒装

所谓让步倒装，主要指的是由as或though引出的倒装形式的让步状语从句。这类倒装句置于句首的可以是形容词、副词、动词或名词等。如：

Successful as [though] he is, he is not proud. 他虽然成功，但不骄傲。

Cold as [though] it was, they went on working. 尽管天气很冷，他们仍不停地工作。

Much as [though] I’d like to, I can’t join you for lunch. 尽管我很想，但我不是不能与你们一起吃午饭。

Hard though [as] they tried, they couldn't make her change her mind. 尽管他们做了很大努力，却没法让她改变主意。

Try as [though] he may, he will not pass the examination. 尽管他可能会努力，他不会通过考试。

Search as [though] they would, they would find nobody in the house. 无论怎样搜查，他们在房子里仍然没有找到一个人。

Boy as [though] he was, he behaved like a girl. 他虽是个男孩，但举止却像个女孩。

注意，这类虚拟倒装有以下语法特点：

1. 当置于句首的名词是单数可数名词时，其前不能用冠词，即使名词前有形容词修饰也是如此。如：

Big puzzle as [though] it was, it hadn’t got the better of Jim. 虽然是个大难题，但仍没有难倒吉姆。

2. 这类让步倒装句式用as或though均可，总的说来，as比though更普通，但是不能用although。

3. 用though时，也可以不倒装；而用as时，必须倒装。如：

虽然她很美，但不聪明。

正：Pretty though she is, she is not clever.

正：Though she is pretty, she is not clever.

正：Pretty as she is, she is not clever.

误：As she is pretty, she is not clever.
