although的基本意思是“尽管,虽然”或“然而,但是”,常用于引导陈述语气的让步状语从句,且引导的句子常指事实,而不指设想。

although可置于句首(此时多用逗号与主句分开),也可置于句末(此时用不用逗号均可),也可用于句中表强调。

在although引导的复合句中，若主句和从句的主语相同，且从句的谓语动词含动词be，则从句的主语和动词be可以省略。

although不能与but在句中同时出现，即有了although就不可以再用but。但although可与副词yet连用而产生关联关系，在含让步状语从句的主句中还可以使用nevertheless, still等副词。

区别although和though: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。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 unhappy though he should have to pve alone.
就算要一个人住，他可能也不会不开心。

He was not unhappy although he had to pve alone.
虽然他不得不要一个人住，却没有不开心。
