英语让步状语从句知识点考点复习
让步状语从句表示“虽然、尽管、即使”等含义，不可和but同时使用，两者只能用一个。但可和yet、still、nevertheless等连用。
①although、though、even though和even if
这几个词或词组都表示“虽然、即使、尽管”。even though和even if语气较强而although和though相对较弱，although较正式而though较通俗。让步状语从句可位于主句前也可位于主句后。例如：
Although our parents often criticize and even beat us, we still love them.
Though I like listening to music, I can’t sing.
Even though (if) he is rich, yet he isn’t happy.
Though most of us are against it, nevertheless I am for it.
在让步状语从句中though和although常可互换，但在下列几种情况下只能用though不能用although。
A、though可和even连用表示强调而although不可以。例如：
Even though the process is full of difficulties, the result is wonderful and satisfactory.
B、though可同as连用构成as though，相当于as if表示“好像”。例如：

   It looks as though it’s going to rain.
