Q2：英语语法 as倒装的让步状语从句？可以。名词表语、状语可以前置，前置后可以加其它限定词，此外，现在进行时中的现在分词，现在完成时或被动语态里的过去分词，含有情态动词的句子中的动词原形，都可以前置，如果是一般动词，这个一般动词可以前置，在主语后面加助动词do、does、did 。
as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中，但although不可以这样用。例如：
Object as/though you may, I’ll go.(=Though/Although you may object, I’ll go.)纵使你反对，我也要去。
Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.）尽管他学习很努力，但几乎没取得什么进步。
Not an adult as/though he was, he knew what was the right thing to do.（=Though he was not an adult, he knew what was the right thing to do.）虽然他是一个孩子，但他知道该做什么。（否定词not放在名词前，一起前置）
Fast as you read, you can’t finish the book so soon.纵然你读得快，你也不能这么快读完这本书。
Strong lover of towns as I am, I realize that I owe a debt to my early country life.尽管我热爱城市，但我知道，以往的乡村生活使我受益匪浅。（形容词放在名词前，一起做倒装）
Small as atoms are, they are made up of still smaller units.尽管原子很小，但它们由更小的单位构成。

Q3：as的倒装句的用法有哪些

adj+as+主+系动词，主句例：Young as he is, he knows a lot.

n（无限定词）+as+主+系动词，主句例：Child as he is, he knows a lot.

adv+主+动词，主句例：Fast as he runs, he can't catch me.
个人认为，这个让步状语从句不是倒装，而是提前，因为从句主谓还是正常语序的。

Q4：英语中as表示虽然时的倒装用法as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前（形容词, 副词, 分词, 实义动词提前）。但需注意：
1）句首名词不能带任何冠词。
2）句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。例如：
Try hard as he will, he never seems able to do the work satisfactorily. 他工作很努力，但总不能让人满意。
注意：让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
