英语倒装

Question

Hard as he worked, he couldn't expect to give a pay rise
这句句子中为什么副词提到了as之前？
让步倒装把表语中的名词、形容词或助动词放在从句谓语之前，这句话怎么解释？
有点例句，谢谢

Answer 1

1. 此句使用了as/though引导让步状语从句时的省略语法。

2. 该语法要求把让步状语从句的名词/形容词/副词/动词或表语/状语/谓语提前，再加as，再加句子其他结构。
其中如果把名词提前，则名词前面的冠词必须省略；
如果把最高级的形容词提前，则其前面的定冠词the必须省略。
如：
1）Child as he is, he knows a lot.
正常句序：As he is a child, he knows a lot.
此句把名词/表语提前。
2）Hard though he worked, he didn't pass the exam.
正常句序：Though he worked hard, he didn't pass the exam.
此句把副词/状语提前。
3）Strongest as he was, he couldn't lift the stone.
正常句序：As he was the strongest, he couldn't lift the stone.
此句把形容词/表语提前。
4）Fail though I did, I wouldn't abandon my goal.
正常句序：As I failed, I wouldn't abandon my goal.来自：求助得到的回答

Answer 2

就是当as 表示“尽管..”之意时（就是引导让步状语从句）要把从句中的表语（名词要省略冠词），修饰动词的副词,，甚至动词放在as之前。如：
Child as he is，he is 180 cm tall.
Try as he may, he failed again.
