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
as
as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。
ShecameupasIwascooking.（同时）
Therunnersstartedasthegunwentoff.（几乎同时）
when
（atorduringthetimethat）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。
Itwasrainingwhenwearrived.（指时间点）
Whenwewereatschool,wewenttothelibraryeveryday.（在一段时间内）
while
while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aperiodoftime时，两者可以互换。
Pleasedon’ttalksoloudwhileothersareworking.
Hefellasleepwhile/whenreading.Strikewhiletheironishot.（用as或when不可，这里的while意思是“趁……”）
（2）引导时间状语从句的连接词除上述外还有：
①till,not…until…,until,before,since
Don’tgetoffthebusuntilithasstopped.
Hewaitedforhisfatheruntil（till）itwastwelveo’clock.
ItwillbefiveyearsbeforehereturnsfromEngland.
②hardly/scarcely…when,nosooner…than,assoonasonce
表示“一……就”
AssoonasIhavefinishedit,I’llgiveyuacall.
Onceyoushowanyfear,hewillattackyou.
Wehadhardlygot/Hardlyhadwegotintothecountrywhenit
begantorain.
Nosoonerhadhearrived/Hehadnosoonerarrivedthanshestartedcomplaining.
③directly,immediately,themoment,theminutethat…一……就
Hemadeforthedoordirectlyheheardtheknock.
④eachtime,everytime,bythetime
Eachtimehecametomycity,hewouldcallonme.
注意：
表示未来情况，主句用将来时，从句用现在时。
2、让步状语从句
（1）although与though可以引导让步状语从句，不能与but连用，但可以与yet连用。
Althoughtheyarepoor,（yet）theyarewarm-hearted.
（2）evenif或eventhough引导让步状语从句，表示“即使”，“纵然”，用来使人注意下文所强调内容的性质。
I’llgetthereevenif（though）Ihavetosellmyhousetogetenoughmoneytogobyair.
（3）nomatter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。
Don’ttrusthim,nomatterwhat/whateverhesays.
Whoeverbreaksthelawwillbepublished.
Nomatterhowhardtheworkis,you’dbettertrytodoitwell.
（4）as也可以引导让步状语从句。
要用倒装。
Childas（though）heis,heknowsalot.
Tryashewould,hecouldn’tlifttheheavybox.
3、原因状语从句：
because,for,as,since,nowthat
（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。
YouwanttoknowwhyI’mleaving?
I’mleavingbecauseI’mfull.
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：
It’smorningnow,forthebirdsaresinging.（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。
Seeingallofthechildrenalreadyseated,hesaid,“Sinceeveryoneishere,let’sstart.”
（3）下列情况下只能使用because:
①在回答why的问句时；
②在用于强调句型时；
③被not所否定时。
4、地点状语从句：
where,wherever
Makeamarkwhereveryouhaveanyquestions.
5、目的状语从句：
that,sothat,inorderthat
6、结果状语从句：
that,sothat,so…that,such…that…
注意：
so+形容词/副词+that从句；such+ 名词+that从句。
7、方式状语从句：
as,asif（though）
I’lldoasIamtoldto.
Itlooksasifitisgoingtorain.
8、比较状语从句：
than,as
9、条件状语从句：
if,unless,so（as）longas,incase,once,afaras,onconditionthat.
注意if与unless的区别：
不能用and连接两个unless从句，即不能有…unless…,andunless…。
但if…notandif…not却不受此限。
10、注意状语从句中从句的省略现象
（1）连接词+过去分词
Don’tspeakuntilspokento.
Pressurecanbeincrasedwhenneeded.
Unlessrepaired,thewashingmachineisnouse.
（2）连词+ 现在分词
Lookoutwhilecrossingthestreet.
（3）连词+形容词/其他
常见的有itnecessary、ifpossible、whennecessary、ifany等。
