7 、让步状语从句

though, although
注意：当有 though, although 时，后面的从句不能有 but ，但是 though 和 yet 可连用
Although it's raining, they are still working in the field.
　 虽然在下雨，但他们仍在地里干活。
He is very old, but he still works very hard.
　 虽然他很老，但仍然努力地工作。
Though the sore be healed, yet a scar may remain.
　 伤口虽愈合，但伤疤留下了。 （谚语）
典型例题
1) ___she is young, she knows quite a lot.
A. When B. However C. Although D. Unless
答案： C 。意为虽然她很年轻，却知道许多。
2) as, though 引导的倒装句
as / though 引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意：
a. 句首名词不能带任何冠词。
b. 句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
　 虽然他尽了努力，但他的工作总做的不尽人意。
3) ever if, even though. 　即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管 …… 都
Whether you believe it or not, it is true.
5) "no matter + 疑问词 " 或 " 疑问词 + 后缀 ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换： no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意： no matter 不能引导主语从句和宾语从句。
　 （错） No matter what you say is of no use now.
　 （对） Whatever you say is of no use now.
你现在说什么也没用了。 (Whatever you say 是主语从句 )
　 （错） Prisoners have to eat no matter what they're given,
　 （对） Prisoners have to eat whatever they're given. 　囚犯们只能给什么吃什么。
