As he is a League member, he is ready to help others.,2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。例如：,他今天缺席，因为他病了。 He is absent today, because / for he is ill. 他一定病了，所以今天缺席。 He must be ill, for he is absent today.,now that, seeing that,（既然）considering that（考虑到） given that, thanks to, in that,（因为） for the reason that等也可引导原因状语从句,8.让步状语从句 1）though, although引导的让步状语从句，后面的从句不能有but，但是 though 和yet, still可连用。例如： Although its raining, they are still working in the field. 虽然在下雨，但他们仍在地里干活。,虽然他很老了，但仍然努力地工作。 He is very old, but he still works very hard. =Although he is very old, but he still works very hard.（错误） = Though he is very old, he still works very hard.,2） 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）。例如： Child as /though he was, he knew what was the right thing to do. 虽然是个小孩，该做什么不做什么，他全知道。 Young as she is, she knows a lot.,3） even if, even though 即使。例如： Well make a trip even though the weather is bad. 即使天气不好，我们也要去远足。,4） whetheror not 不管都。例如： Whether you believe it or not, it is true. 信不信由你，这确实是真的。,5） “no matter +疑问词” 或“疑问词+后缀ever” 。例如： No matter what happened, he would not mind. =Whatever happened, he would not mind. 不管发生什么，他不在意。,9.比较状语从句 由从属连词asas, not so (as) as, than, the + 比较级（从句）+ 比较级（主句）等引导。 Hangzhou is not so (as) large as Shanghai.
