额 用AS的时候 不仅仅是表语 状语放在句首,谓语动词也是可以倒装的
(1) 副词（状语或定语）置于句首.如：
Best as I like it (＝Although I like it very much),I will not buy it．
(2) 动词原形（谓语动词）置于句首.Wait as you may(＝Although you may wait),he will not see you．
(3) 形容词或名词（表语）置于句首.注意：如果表语是名词,则要省掉冠词,如：
Child as he is (＝Although he is a child),he can tell right from wrong
