关于英语中几个低级问题

though 和although的区别
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(
