as引导让步状语从句动词位于句首必用原形?

如题所述

as可引导让步状语从句,表示“虽然、尽管”,但要用部分倒装结构,形式如下:
1. 形容词 + as + 主语 + 系动词。如:
Tired as he is, he offers to help me.
尽管他已经很累了,他还是主动提出帮助我。

2. 过去分词 + as + 主语 + 系动词。如:
Well-written as the book is, the author is not satisfied and prepared to revise it.
尽管这本书写得很好,作者还是不满意并打算修改它。

3. 名词 + as + 主语 + 系动词。如:
Student as he is, he does not study hard.
他虽然是个学生,却不努力学习。

4. 副词 + as + 主语 + 谓语部分。如:
Much as I admire his courage, I don’t think he acted wisely.
我虽然崇拜他的勇气,但我认为他这样做是不明智的。

5. 动词原形 + as + 主语 + 谓语的另一部分(情态动词或助动词may, might, will, would等)。如:
Try as you will, you won’t be able to persuade him.
不管你怎么努力,你都说服不了他。

as引导让步状语从句时要倒装(形容词/ 副词/ 名词/ 动词 + as + 主语 + 谓语)。
如:Try as he would, he couldn’t open the door.

在这个句式中,位于句首的动词要用原形,因为时态通过主语后的谓语来表示,即使需要变位也是通过主语后的谓语动词或助动词变位。如例句中,would表达出时态和语态。
