地点状语从句与定语从句的区别:在于分句在句中作什么成分。
作状语，则是状语从句；作定语修饰名词，则是定语从句。
where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。
如：Go back where you came from.(where引导地点状语从句）Go back to the village where you came from.(where引导定语从句，修饰village)We went home, where we had dinner. (where引导定语从句，修饰home)2、原因状语从句原因状语从句一般由because(因为)，since(既然)，now that(既然，因为)，as(由于)等连词引导。
（1）because表示直接的原因，表示原因的语气最强，常表示必然的因果关系。
回答why引起的特殊疑问句，只能用because。
Jane wore a raincoat because it was raining.因为天下雨，所以詹穿着雨衣。
He is absent today because he is ill.他今天缺课，因为他病了。
（2）since表示对方已经知晓、无须加以说明的原因或事实，语气比because稍弱。

初中英语状语从句和练习题(含答案)
状语从句一、时间状语从句时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since等。
时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。
注意：as（在……时候，因为），since（自从，因为），它们可以引导时间从句，并强调主句和从句的动作同事发生。
并且while有时还可以表示对比。
例如：（1）While my mother was reading the newspaper, I was watching TV.(read是延续性的动词，read和watch同事发生)I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。
（对比）（2）when（当……的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。
从句动作可与主语动作同事发生，也可在其后发生。
I was reading a book when she came into my room.(come是瞬间动词，只能用when引导，不能用while)I often missed my home when(while) I lived in NewYork.（live是延续性动词，when可用while代替）（3）when和while的区别还在于：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。
（4）as译作“一边……一边”、“随着……”，侧重主句和从句的动作同时发生。
有时可与when，while通用。

1．When , while, as都可解释为“当```的时候”但侧重点有所不同。
1)WhenEg: When I arrived home , I had a little rest.注意点：when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。
Eg: When (she was) walking along the street, she met her class teacher.2)AsAs 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”Eg: He sang as he danced.(一面```一面)You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。
Eg: While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意点：while 有对比的含义，解释为“然而”。
eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。

根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。
各类状语从句连接词（短语）一览表：时间when, while, as, as soon as, since, until, after, before ，as long as（长达……之久）条件If, unless,as/so long as（只要）原因As, because, since ，as/so long as（既然,因为）地点Where目的So that（为了）, in order that结果So that （方便）, so… that, such … that 让步though, although, even if, however 方式As比较than, （not）as … as1.时间状语从句时间状语从句常见的从属连词有：（注意其汉语意义）when, while, as, before, after, since, until （till） once as soon as, the moment, the minute, immediately, directly, each/every time, the first time, the last time, next time, by the time, whenever 等。
例如：Every/Each time I was in trouble, he would come to my help.I thought her nice and honest the first time I met her. 注意：（1）when, while,as 的区别：1）when 引导从句时，主从句的动作有先有后，也可以同时进行,从句的动作可以是持续性的，也可以是短暂的。
如：When I got to the airport, the plane had already taken off. （主先从后）（短暂性）When I lived there, I used to go to the seaside on Sundays. （同时）（持续性）When the movie ended, the people went back. （从先主后）2）while 侧重主从句动作的对比，且从句的动词必须是持续性的。
如：While we were chatting she was looking at the time table on the wall．3）as 引导从句时侧重主从句动作同时或几乎同时进行，从句的动作可以是持续性的，也可以是短暂的。
如：Sometimes I watch TV as I am having breakfast．4）when 和while 还可以是并列连词，意思分别是“就在这时”，“然而”。
如：I was having a rest on the sofa when the telephone rang．They were surprised that a child should work out the problem while they couldn' t .注：并列连词when 常用与以下句型中：①…was/were doing…when…（正在做…突然）②…was/were about to do…when…（刚要做…突然）③…was/were on the point of doing…when…（刚要做…突然）④…had justdone…when….（刚一…就）⑤Hardly/Scarcely had…done…when…（刚一…就）（2）before 引导从句时,词义非常灵活，注意下列句子中的before 的词义：1.Before I could get in a word, the tailor had measured me.（还没来得及…就）2.We hadn't run a mile before he felt tired.（还没…就）3.We had sailed 4 days before we saw land.（…才…）4.Please write it down before you forget it.（趁还…没就）（3）till （until）和not…till （until）1）till （until）:主句谓语动词必须是持续性的，意思是“到…为止“如：He remained there till/until she arrived.2）not…till （until）…: 主句谓语动词必须是短暂性的，意思是“直到…才” 如：She won't go to bed till/until he returns home.3）not…until 还有强调式和倒装式：强调句：It is not until he returnshome that she will go to bed. 倒装句：Not until he returns home will she go to bed.（4）几个极易混淆的时间状语从句：1）It was +时间点+when…（当的时候时间是）It was 5 am when we arrived at the village.2）It was/will be+时间段+before…（没过…就／过了…才）It was/will be two weeks before we met/meet again.3）It is /has been +时间段+since…（自从…以来有…）It is/has been 3 years since we last met. 突破点：一看be 动词的时态，二看时间段还是时间点。
注意：在“It is /has been +时间段+since…”句型中，从句的动词必须是短暂性的，如果是延续性的动词，时间要从从句的动作结束时算起。
如：It is 3 years since I smoked.（我戒烟有三年了）补充：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no so oner…than…, hardly/scarcely….when….和once 这些从属连接词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一…就…”。
从句中一般时态代替将来时态。
every time, each time, next time, the first time, any time, all the time等名词短语用来引导时间状语从句，表示“每当…..，每次…..；下次……”等。
