昆明顺企网:怎样能记住让步状语从句（或说快速判断出）

有转折意味的既为让步状语从句

让步状语从句是状语从句的一种，表示：虽然，尽管，即使等概念，由although（尽管）, though（尽管）, however（无论怎样）, whatever（无论什么）, whoever（无论谁）, whomever（无论谁）, whichever（无论哪个）, whenever（无论何时）, wherever（无论哪里）, whether（是否）, no matter (who, what, where, when, etc) （无论……）, even if（即使）, even though（即使）等词引导。

注意对让步状语从句的掌握要注意以下几点内容。
1) 使用though, although时，务必避免与but连用。
2) even if, even though和as if, as though不同。后者常常要求使用虚拟语气。
特别提醒

1.no matter

what（who，which，when，etc。）与whatever（whoever，whichever，whenever，etc。）的区别：

当引导让步状语从句时，两者相同，可以互换，但当引导名词性从句（主语从句，宾语从句，表语从句和同谓语从句）时则只能用whatever（whoever，whichever，whenever，etc）。如上面最后两个例句可改为：

e．g． However pure the water looks，I do not want to drink it。

I want to marry the man I love， no matter who he may be。

下面句字不能用no matter结构:

Whoever comes back firs is supposed to win the prize.(主语从句)

I am ready to do whatever you want me to .（宾语从句）

2. as 引导让步状语从句的用法：

引导让步状语从句时，as意为“虽然，尽管”，通常从句要倒装，倒装的方法是将从句的表语或状语放在as之前，而用though引导让步状语从句时句字则不必倒装（口语中也可倒装）。

e.g. Heavily as it was raining outside, they started out very early.

Young as he is, he knows a lot=Though he is young 或Young though he is, he….

他虽然年轻，但懂得很多。(though 也有这种用法，可以替换as,但although没有这种用法)

though还可以用作副词，放在句末。如：

It was hard work;; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦，但是我喜欢干。

3.用though/although, as 引导让步状语从句时，句中不能用but表示转折语气。

不能说：Though he looks weak, but he is healthy.

而要说：Though he looks weak, he is healthy.

或者说：He looks weak, but he is healthy。
