倒装句中as和although当尽管讲时的用法
as和although虽然都可以引导让步状语从句,是"虽然,尽管"的意思,但区别在although只用于句首,而as不能位于句首。此外,although引导的句子不倒装,though可倒装也可不倒装,而as一定要倒装
as、although这两个个词的用法各有区别。具体来说,as引导的让步状语从句必须倒装;而although引导的让步状语从句不能倒装。
as 引导让步状语从句的情况:
1、主+系+ 表(形容词、名词)
表(adj)+ as + 主+系 Young as he is,he knows a lot。
表(n )+ as + 主+系 Child as he is,he knows a lot。(名词前不能加冠词)
2、主+ 谓+ (宾)+状语
状语+ as +主+ 谓+ (宾)Many times as he failed the experients,he never lost courage。
although倒装句使用
名词/形容词/副词/动词+although/though/as+主语+谓语
用名词时,不守冠词要省略。用动词时,只有谓语动词是情态动词+动词原形时,才能这样用。
