状语从句（1）时间状语从句：在一个句子中作时间状语的句子。

时间状语的连接词：when(当…时候) while(当…时候) as(当…时候) after(在…以后) before(在…以前) as soon as(一…就) since(自从…到现在) till /until(直到…才) by the time(到…为止)连接词后加陈述语序。

例：It was snowing when we got to the airport.（2）原因状语从句：在一个句子中作原因状语的句子。

连接词：由连词because, since, as等词引导。

★ because 意为“因为”，表示造成某种情况的直接原因，语气最强，常用“why”提问举例：He took off his coat because it was too hot in the room.★ since往往表示众所周知的原因，多意为“既然” since从句通常位于主句之前，其语气比as稍强。

例如：Since you won't help me，I'll ask someone else.★ as表示原因时，语气最弱，意为“由于”例如：As you were out，I left a message for you.（3）条件状语从句：在一个句子中作条件状语的句子。

连接词：if如果, unless (=if not) 除非，as/so long as（只要），once（一旦）举例：If I am free tomorrow，I will help you with your English.（4）目的、结果状语从句目的状语从句连接词so that, in order that 引导。

例如：Speak louder so that the people in the hall can all hear you.结果状语从句连接词 so…that, such…that, so( that)举例：so…that 如此…以至于I'm so knowledgeable that I can help students study.★ so that 引导目的状语和结果状语的区分：1.意思有区别表示目的状语从句时，意思为： 以便, 为了,为使。

表示结果状语从句时，意思为： 结果是，所以。

2.引导目的状语从句常常与can, could，may，might，will，would，shall，should，等连用.例如：So that everyone will notice her，she dresses like an angel.3.引导目的状语从句通常不用逗号隔开，引导结果状语从句一般有逗号隔开。

例如：We’ll come at eight so that the meeting can begin early.（目的状语）We arrived early in the morning，so that we caught the first train.（结果状语）（5）让步状语从句让步状语从句是指在句子中作让步的状语的句子连接词： though, although,even though,even ifthough/although引导让步状语从句时，主句中不能再用but，但可以用yet举例：Although he is rich, yet he is not happy.no matter引导让步状语从句：结构："no matter +特殊疑问词疑问词+陈述语序" 或"特殊疑问词+后缀ever+陈述语序"如：whenever I'm unhappy, it is my friend who cheers me up.＝No matter when I'm unhappy, it is my friend who cheers me up.类似此类还有：whatever＝no matter whatwherever＝no matter wherewhoever＝no matter whohowever＝no matter howwhenever＝no matter when注意：no matter 不能引导主语从句和宾语从句。

（6）地点状语从句在句中作地点状语的从句称为地点状语从句，可至于句首句中和句尾。

常见引导词有where,wherever等。

例句：We live where the road crosses the river.（7）方式状语从句方式状语从句常见引导词有：as（如同，按...方式），as if，as though等★ 方式状语从句所表示的情况是事实或可能性很大时，通常用陈述语气。
