省略句是高考英语常考的一类句型，省略句的种类主要有：主语的省略、谓语的省略、状语从句的省略、不定式的省略。下面就在状语从句中的省略进行学习。　

一、如果从句的主语和主句的主语一致，且从句的谓语含有be动词的某种形式（am/is/are/was/were），可同时省略从句的主语和be动词的某种形式。

　　1、when，while引导的时间状语从句

e.g.?Do?be?careful?when?(you?are)?crossing?the?street.When/While?(I?was)?on?my?way?to?work,?I?met?her.

　　2、if，unless，once引导的条件状语从句e.g.?If?(it?is)?properly?treated,?waste?will?do?no?harm?to?the?environment.

　　I’ll?not?go?to?the?party?unless?(I?am)?invited.

Once?(you?are)?caught?stealing?in?a?supermarket,?you?will?

be?punished.

　　3、though，although，whether，no?matter?whether/what/how/who等引导的让步状语从句

　　e.g.?He?was?happy,?though/although?(he?was)?poor.Whether?(she?is)?sick?or?well,?she?is?always?cheerful.

No?matter?how/However?hard?the?task?(is),?we?must?fulfill?it?in?time.（注：从句的主语和主句的主语不一致时，只省略从句中的be动词形式）

　　4、as?if，as?though引导的方式状语从句

e.g.?He?rubbed?his?eyes?and?yawned?as?if/though?(he?was)?waking?up?after?a?long?sleep.

　　He?stood?up?as?if/though?(he?wanted)?to?leave.（as?if/though?+?to?do表示一个将来的动作）?

　　二、than，as引导的比较状语从句中的省略用法：

　　当不同的主语进行比较时，一般省略从句中的谓语；当从句中的主语与谓语（be动词除外）和主句中的主语与谓语相同时，通常省略从句中的主语和谓语，只保留比较部分。

　　e.g.?He?is?taller?than?his?brother?(is).

I?have?as?much?as?confidence?in?you?as?(I?have?confidence)?in?him.

　三、以if从句为代表的状语从句中的特殊省略用法：通常省略了it?is，that?is，there?is/are。

　　e.g.?If?(it?is)?possible/necessary,?this?old?temple?will?be?rebuilt.

If?(that?is)?so,?I?will?call?you?back?at?5:00?pm.

　　There?are?only?a?few?books?in?our?school?library,?if?(there?are)?any.

另外，还有几个固定的表达；if ever if never if possible if any
