Question

倒装句中as和although当尽管讲时的用法

Answer 1

as引导的让步状语从句倒装有四种类型（强调让步内容，as可以用though代替）。现在我来给你讲
第一种：adj+as+主语+be
第二种：名词（特别注意是不带冠词的）+as+主语+be
第三种：adv+as+主语+动词
第四种：动词原形+as+主语+动词或助动词
as, though ,although这三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;though引导的让步状语从句可以倒装也可以不倒装;而although引导的让步状语从句不能倒装.
e.g. Hard as he tried, he still failed. (他虽然努力了,但仍然失败了.)

Though he tried hard, he still failed.
Hard though he tried, he still failed.

Although he tried hard, he still failed.
