(2)though 还可用作副词，置于句尾。 e.g. He said he would come ,he didn't ,though. 4 as /though (倒装) as /though位于句首，从句中的表语、状语、动词原形提前。若表语是单数名词，前置时要省略冠词。 e.g. Child as/though he is ,he can swim well. Much as/though I like it , I won't buy it . wh-ever和no matter wh- 1.wh-ever 和no matter wh-都可以引导状语从句 e.g. No matter when he comes back, he should be invited to the party. =Whenever he comes back, he should be invited to the party. 2.wh-ever 还可以引导名词性从句,no matter wh-不可以。 e.g. You can take whatever you like. when,while when,while 也可以做从属连词，让步状语从句，引导相当于although。 e.g. Suddenly,she stopped when she should have continued. While I admit that there are problems ,I can't agree with you . 真题演练 【考例1】 　　______ I always felt I would pass the exam, I never thought I would get an A. (2012湖南) 　　 A. While B. Once 　　 C. If D.
