as / though引导让步状语从句时要用倒装吗
as / though引导让步状语从句时,一般须用部分倒装。如:
Old as / though he is, he works like a young man. 尽管他很老了,但他工作起来却像个年轻人。
Hard as / though he was working, he didn’t pass the exam. 虽然他一直在努力学习,但他还是没有通过那次考试。
Try again as / though he will, he can’t succeed. 尽管他还会再试一试,但是它不会成功。
as / though引起的倒装分三种情况:表语、动词原形及状语的倒装。
1. 表语的倒装
一般直接将表语提前到句首,若表语是带不定冠词a / an的单数可数名词,倒装后,不定冠词a / an须被省略。如:
Fine as / though he looks, he is ill with some serious diseases.
Child as / though he is, he knows much about the society.
2. 原形动词的倒装
A. 动词前面带有情态动词may, might, will, would, can, could等时,只将行为动词提到句首,而这些情态动词保留在原处。
B. 若动词前面没有情态动词时,应在动词原来的位置加上助动词do的适当形式。
C. 用于这一句型的动词一般是不及物动词,而不能是系动词或及物动词。如:
Swim as / though he can, he can’t swim so far. 尽管他会游泳,但是他游不得那么远。
Run as / though he did, he didn’t run fast enough to catch the bus. 虽然他跑,但是他跑得不够快而没有赶上汽车。
3. 状语倒装
In the classroom as / though he stays, he doesn’t read his texts. 尽管他呆在教室里,但他不读书。
Carefully as / though he worked, he made some mistakes. 尽管他工作很细心,但还是除了一些差错。
