though，although引導(dǎo)讓步狀語從句時，后面的主句不能有but，however，但是可與yet，still連用。
1. although和though同義，在一般情況下，可以互換使用。只是though較普遍，常用于非正式的口語或書面語中，而although則較為正式。另外although語氣比though重，常用以強調(diào)讓步概念。
e.g. Though/Although my car is very old, I don't want to buy a new one.
同義句：My car is very old, but I don't want to buy a new one.
雖然我的汽車很舊，但我不想買一輛新的。
2. even能和though組合表示強調(diào)，但even不能和although組合。因此，不能說even although,在這里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.
即使我們付得起這筆錢，也不出國度假。
3. 當(dāng)讓步狀語從句指某種假設(shè)情況時，通常用though,而不用although。
e.g. Though all the world were against me, I should still hold to my opinion.
就算全世界都反對我，我還是堅持我的立場。
4. though可以獨立用作副詞，常放在句末，意為all the same (還是；仍然)或however(可是；然而)，而although無此用法。
e.g. She didn't tell me what she had done, but I know it though.
她沒有告訴我她所做的事情，但我還是知道了。
5. although和though引導(dǎo)讓步狀語從句時，常采用省略形式。
e.g. Although tired (=Although he was tired), he kept on working.
雖然很疲勞，但他繼續(xù)工作。
