1、状语从句修订版状语从句 1、时间状语从句 （1）as、when、while用法一览表。类别作 用例 句asas表示“当的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。She came up as I was cooking.(同时)The runners started as the gun went off.(几乎同时)when(at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。It was raining when we arrived

2、.(指时间点)When we were at school, we went to the library every day.(在一段时间内)whilewhile意思是“当的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。Please dont talk so loud while others are working.He fell asleep while/when reading. Strike while the iron is hot.(用as或whe

6、”，用来使人注意下文所强调内容的性质。Ill get there even if(though)I have to sell my house to get enough money to go by air.（3）no matter后接上who、what、where、how等疑问词，也可以在这类疑问词后面加上ever构成whoever、whatever、wherever、however等。Dont trust him, no matter what / whatever he says.Whoever breaks the law will be published.No matter ho

7、w hard the work is, youd better try to do it well.（4）as也可以引导让步状语从句。要用倒装。Child as(though)he is, he knows a lot.Try as he would, he couldnt lift the heavy box.3、原因状语从句：because, for, as, since, now that（1）表示不知道的原因时用because,即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。You want to know why Im leaving? Im

8、 leaving because Im full.for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。如：Its morning now, for the birds are singing.（很显然，鸟叫不可能是“现在已是早上”的原因。）（2）表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前，但有时却相反。Seeing all o

9、f the children already seated, he said,“Since everyone is here, lets start.”(3)下列情况下只能使用because:在回答why的问句时；在用于强调句型时；被not所否定时。4、地点状语从句：where, whereverMake a mark wherever you have any questions.5、目的状语从句：that, so that, in order that6、结果状语从句：that, so that, so that, such that 注意：so + 形容词/副词 + that从句；suc

11、连接词 + 过去分词Dont speak until spoken to.Pressure can be incrased when needed.Unless repaired, the washing machine is no use.（2）连词 +现在分词Look out while crossing the street.（3）连词 + 形容词/其他常见的有it necessary、if possible、when necessary、if any等。基础训练题1.
