although和though的区别
- 语气不同
两词都可表示"虽然"，但although语气较though更重，通常放在句首并用于正式场合，though多用于口语。although、even though和though可用于句首或带有动词的从句开头
eg：I'd quite like to go out,(al)though it is a bit late.
eg：Although it was snowing,it was not very cold.
eg：Although/Though we are poor, we are still happy. - 强调词位置
用though时，可将强调的词前置，though引导的让步状语从句可用部分倒装，但although不能
eg：Poor though he is,he is happy.
eg：Child though she was,the actress was drawing a crowd. - 从句性质不同
although引导从句常指事实，而though引导的句子可表假设
eg：Let's start as arranged though it rains tomorrow.
eg：He was not unhappy although he had to live alone. - 用作副词
although只用作连词，而though除作连词外，还可用作副词，常置句末，句子较长时，也置于句中，意为“可是”、“不过”
eg：It's hard work,I enjoy it though.
eg：You can count on him,though. - 习惯用语
as though好像，仿佛
eg：They looked at her as though she was crackers.
even though即使，纵然，哪怕，纵然
eg：I still love you even though I'd like to wring your neck.
