让步状语从句中的倒装知识点考点复习 though引导的让步状语从句可以运用倒装结构而其它从属连词则不可以。在倒装结构中，though可用as或that代替。但用as和that引导让步状语从句时必须倒装。倒装形式主要有以下几种。 A、名词+though（as、that）+主语+be动词 Manager though(as、that) he is, he is very modest. 这时作表语的单数可数名词放在句首时，名词不能同冠词连用。 B、形容词+ though（as、that）+主语+谓语 Strong though you are, you can’t lift it. 这时作表语的形容词前不能添加任何表示程度的副词。 C、副词+ though（as、that）+主语+谓语 Hard as he works, he was unable to make great progress. D、原形动词+ though（as、that）+主语+助动或情态动词 Fail many times as he did, he never lost heart. Search though they might, they can’t find anybody in the house. 谷雨刷题王 单词快速记忆法 新概念英语青少版 E、现在分词+ though（as、that）+主语+be动词或助动词 Raining as it is, I’m going to visit you. Living, as he does, alone in the mountain, he feels pleased. F、过去分词+ though（as、that）+主语+be动词 Praised as he was, he remained modest. 但上述有些结构并非总是表示让步，名词或过去分词放在句首时也可以表示原因。例如： Child as he is, he doesn’t experience some social problems. Born as he is in a rich family, he grows up better than others. Tired as he was, he stopped working and went to bed.（原因） Tired as he was, he continued to work.（让步） 练习： 31.
