although和though的用法区别

1.though可以做副词，指“但是”，但是although不行。as though属固定搭配，though不能替换成although。although要比though来得更正式，相对而言，语气比较重，但是though的使用更普遍。

2.although引导的从句，常指实际发生的事情，而不是假象，设想。though和although都可在从句中用作连词，通常表示相同的意思，但though更普遍适应于非正式的表述中。

He said he would come, he didn't, though.

句中的though不能替换成although。

He would not be unhy though he should have to live alone.

就算要一个人住，他可能也不会不开心。

He was not unhy although he had to live alone.

虽然他不得不要一个人住，却没有不开心。

3.although的语气较重,引导的句子常指事实; though引导的句子可表示假设。

4.though可以引起从句的主语和谓语部分倒装，而although不可以。

5.although只用作连词; 而though除用作连词外,还可用作副词。另外，though可用作并列连词，也可用作从属连词；而although只能用作从属连词。

6.though可用于even though, as though, what though等结构; 而although不能。
