* * 高三英语总复习语法系列训练 让步状语从句专讲 让步状语从句通常用 though, although, no matter, even if, if, even though, however, whatever等引起。 △ 让步状语从句可以前置，也可以后置；前置时强调主句内容，后置时强调从句内容。有时也可以采取中位（插入句中）。 1．although 和though 引导的让步状语从句： ①?两个词同义，一般情况下可以互换使用，如： He didn’t light the fire though / although it was cold. ② although 比though 较正式，语气较重，常用于强调让步概念，如： He insisted on doing it although I warned him not to. ③ though可以和even 连用，但although 不可以，如： Although (Even though) the traffic held us up, we got to the airport on time. ④ 当让步状语从句是指一种假设的情况，不指事实时，通常用though，而不用although，如： He will never do such a thing though he (should) be forced to. Though all the world were against me, I shall still hold to my opinion. ⑤ though可以在非正式文体中用作连接性状语，而although 则不行。（though 可以放在句中或句末，通常用逗号隔开），如： He said he would come; he didn’t, though. ⑥ though引导的从句可用倒装语序（即把从句中的表语或状语等放在though之前），而although 不能这样用，如： Young though she is, yet she is fit for the job. (= Young as she is, …) ⑦ 有时可用副词yet, still, nevertheless (但不能用连词but) 来配合连接词though或although，以加强语气，如： Though he is over seventy, yet / still / nevertheless he can ride the bike. ⑧ though和although后面的主语和谓语动词be 可以省略，如果这个主语和主句中的主语指同一个人或物时，如： Though (it was) cold, it was a fine winter morning. Though (he was) severely wounded, yet he refused to leave the battle field. Though (they were) very tired, they continued to march on. 2．even if, even though和 if 引导的让步状语从句： △ even if 与 even though同义，常用于强调让步概念，如： I’ll do it, even if it takes me all the afternoon. He was there even if we didn’t see him. Even if you fail, you can try again. I’ll help you, even if I don’t sleep for a night. 注：if 有时也可以用于让步含义，但要注意条件if 与让步if 的区别，试比较： If he is poor, how can he buy the house? (条件) If he is poor, he is at least honest. (让步) (= even if) If he is inexperienced, he won’t be able to accomplish it. (条件) If he is inexperienced, he is at any rate eager to learn. (让步) (= even if) If John had been there, I would have seen him. (条件)
