As引导让步状语从句倒装的用法
一、名词 + as / though + 主语 + 动词
King as he was，he was unhappy. 他虽是国王，但他并不幸福。
Child as he is，he knows to help other. 他虽是个孩子，却知道帮助别人。
【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。比较：
Boy as ［though］ he is， he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。
Strong man as ［though］ he is，General Botha has been severely put to the test during the past few weeks.= Though he is a strong man， General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。

二、形容词 + as / though + 主语 + 动词
Successful as he is，he is not proud. 他虽然成功，但不骄傲。

【说明】其中的动词也通常为连系动词，也就是说位于句首的形容词是其后连系动词的表语。

三、副词 + as / though + 主语 + 动词

He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很大进步。
【说明】有的词典将 much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。再如：
Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人。
Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活。
