Though与 Although有什么区别?它们在引导让步状语从句时需不需要倒装?

1.although连接的让步状语从句,后面主句中不能再用连接词but.2.although和though 同义,基本上可互换使用,但习惯上句首多用although.另 外,在短语even though（即使）和as though（仿佛,似乎）中不能换用 although.区别：①although和though同义,在一般情况下,可以互换使用.只是though较普遍,常用于非正式的口语或书面语中,而although则较为正式.另外although语气比though重,常用以强调让步概念.e.g.Though/Although my car is very old,I don't want to buy a new one.虽然我的汽车很旧,但我不想买一辆新的.He insisted on doing it although I warned him not to.虽然我警告他不要做,但他仍然坚持要做.②even能和though组合表示强调,但even不能和although组合.因此,不能说even although,在这里even though=even if(no matter if; though即使……也……) e.g.Even if/Even though we could afford it,we wouldn't go abroad for our vocation.即使我们付得起这笔钱,也不出国度假.③当让步状语从句指某种假设情况时,通常用though,而不用although.e.g.Though all the world were against me,I should still hold to my opinion.就算全世界都反对我,我还是坚持我的立场.Though everybody deserts you,I will not.即使所有人都抛弃你,我也不会的.④though可以独立用作副词,常放在句末,意为all the same (还是；仍然)或however(可是；然而),而although无此用法.e.g.She didn't tell me what she had done,but I know it though.她没有告诉我她所做的事情,但我还是知道了.It's hard work.I enjoy it,though.工作很苦,可是我喜欢.⑤though引导让步状语从句时可以倒装,而although从句则不能.e.g.Bravely though they fought,they had no chance of winning.虽然他们打得很勇敢,但还是没有机会获胜.相同点：①在although和though引导的让步状语从句中,主句里不可用but,若要强调前后两部分的对比意义,可在主句前加yet或still.e.g.Although/Though he has a lot of money,yet/still he is unhappy.他虽然有很多钱,但并不幸福.②although和though引导让步状语从句时,常采用省略形式.e.g.Although tired (=Although he was tired),he kept on working.虽然很疲劳,但他继续工作.The problem,though complicated(=though it is complicated),can be solved without much difficulty.这个问题虽然复杂,但解决起来不会有很大困难.
