一、条件状语从句

条件状语从句引导词有if, as long as等。常用if引导条件状语从句。if意为“如果”，它引导的句子表示某事发生所需要的条件，即“在......条件下某事才能发生”， 在句子中充当状语，因此叫“条件状语从句”。

1.if从句 祈使句，相当于汉语的“如果......，就......”。if引导的条件状语从句不是指已经发生的事件，而是指能够发生或可能发生的事件。该结构还可以用来表达建议。

如：If you want to come here tomorrow, email me first./Email me first if you want to come here tomorrow./If you don’t feel well, please go to see the doctor./Please go to see the doctor if you don’t feel well.

2.if引导的条件状语从句表达某种假设的情况，主句则表示此种情况所导致的结果。从句如果用一般现在时，主句的谓语多用一般将来时或“情态动词 动词原形”。如：

If I start after dinner, I’ll finish it before I go to bed./She may come with us if she arrives in time.

注意：if 引导的条件状语从句可以放在主句前，也可以放在主句后。从句置于主句前，须有逗号与主句隔开。反之则不用逗号。

二、让步状语从句

让步状语从句引导词有although, though, even if, even though, 特殊疑问词 ever(whatever, wherever...）, no matter 特殊疑问词(no matter how, no matter where...)等。 常用although/though引导让步状语从句，意为“尽管......，（但是）......”。一般情况下，although和though引导的让步状语从句可以互换使用。口语中，though较为常用。如：I can look after myself, although it won’t be easy for me./Although she is alone, she is happy at first./Great men never give up, no matter what difficulties they face.

注意：汉语中“虽然/尽管”与“但是”往往同时使用，但在英语中although/though和but是不能同时使用的，可以与yet同时使用。如：Although/Though I don’t often make dinner,（yet）I can cook.此句意思就是I don’t often make dinner, but I can cook.
