【考点一】对时间状语从句的考查

（1）when，while，as三者都意为“当……的时候”，when最常用，由其引导的状语从句中谓语动词可以是延续性动词，也可以是非延续性动词；while从句中的谓语动词只能是延续性动词；as引导的从句中表示的动作常与主句表示的动作同时发生。中考主要考查前二者的区别。

（3）until/till意为“到……为止”。表示动作结束；而not…until/till则意为“直到……才……”，表示动作开始。

（4）since意为“自从……”；assoonas意为“一……就……"。

【考点二】对条件状语从句的考查

（1）条件状语从句常由if，unless，as/solongas等从属连词引导。主句的谓语动词是一般将来时，从句的谓语动词应用一般现在时表示将来要发生的动作或存在的状态。

不要将if引导的条件状语从句与由其引导的宾语从句混淆，也不能用whether来替换if。

区分这两句话：Iwillbeveryhappyifyoucometomybirthdayparty.

Idon’tknowifhewillcometomybirthdaypartytomorrow.

（3）含有if条件状语从句的主从复合句可以替换为：祈使句+and/then/or+分句（通常用将来时）。

【考点三】对原因状语从句的考查

（1）because，as，since都有“因为”之意，中考一般以考查because为主。

1.because

A.语气最强

B.用来说明人们不知道的原因

C.回答why提出的问题D.不与so连用

Ididn'tgotoschoolyesterday,becauseIwasill.

2.since

A.表示"既然"B.显而易见的原因

Sinceeverybodyishere,let'sbeginourmeeting.

3.as

A."因为",较为口语化B.通常放句首,不可用于强调结构

Asyouareinpoorhealth,youshouldnotstayuplate.

4.for

A.用来作为附加说明，是间接推断B.不可放句首

Iaskedhertostaytohavetea,forIhadsomethingtotellher.

（2）和汉语的用法习惯不同，在英语中不能将because，since或as与so用在同一个句子中。

—No.Tomisathome_hehasgotabadcold.

A.because

B.if

【考点四】对让步状语从句的考查

（2）它可以和but引起的并列句换用，但两者不能同时运用。

whether

1.“不管",常与or…not连用

2.引导的从句旨在说明正反两方面的可能性不会影响主句的意向或结果

Whetherheisgoodornot,thecompanydecidedtosendhimabroad.

疑问词+ever

1.Whatever,whoever,whichever,wherever,whenever

2.注意：however（不论）引导状从，句子常倒装

Hecouldn'tgetthereontimehoweverfasthedrove.

nomatter+疑问词

1.nomatter(what,when,where,how,who)

无论（什么，何时，何地，怎样，谁）

Hewouldn'tforgivemenomatterhowhardIbeggedhim.

【考点五】对结果状语从句的考查

（1）so...that，such...that都是“如此……以至于……”之意。so...that以“so+形容词，副词+that"及“so+形容词+a/an+名词”结构最为常见。such...that常见于“such+a/an+形容词+名词”结构。中考主要以考查so...that为主。

(2)结果状语的两种句式:so+形/副十that--与such+(a/an)+形+名十that...如此.....以至于.....

TomissocleverthathelearnsChinesewell.

=TomissuchacleverboythathelearnsChinesewell.

（3）so...that可与too...to和enough...to结构互换使用，但要注意它们之间的替换方式。
