although 和 thoughalthough 和 though有什么区别?最好能弄个例句.意思上有没什么差异?对了,还有even though

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.
