爱华网在高考英语试题中，复合句占有较大的比例，复习时应该注意：
1.倡发散思维，忌单向思维，考各种从属句，常常是不同类型的连接词语正误连缀而至，如果不抓住这一点，不从多方面思考选择，就容易以偏概全， 误入歧途。
2.弄清主从复合句中的每一个从属连接词的意思、用法、主句与从句在时态上的呼应、语气、是否需要倒装、固定搭配及逻辑常识等。
3.熟记句型及特殊表达形式。
4.注意各分句之间的特点及区别。
5.注意有些连接词的省略情况及省略后某些语序发生的变化。
总之在做习题时，不能生搬硬套，一成不变，要全方位的思考，摸清出题者的意图，灵活机动，随着不同的语言环境而变化。
一、状语从句：状语从句又可分为时间、地点、目的、原因、结果、行为方式、条件、让步及比较等几种形式。
1.I'll go with you as soon as I ____my work.
A.will finish B.shall finish C.finish D.finished
选C.在时间、条件状语从句中，主句可能是祈使句、一般将来时或带情态动词，从句用一般现在时。如 果主句是过去将来时，从句可以用一般过去时。能够引导时间状语从句、条件状语从句的从属连接词，常见的 有：when,until (ti y,directly,unless,as long as,suppose等。如：
(1)Unless he comes,we won't be able to go.
(2)Suppose it goes on raining,what shall we do?
(3)Lu Xun often said,"As long as I am alive,I shall go on studying."
2.No sooner_____the news than they rushed out into the street. A.they heard B.they had heard C.did they hear D.had they heard 选D.no sooner…than,hardly… when,scarcely… before表示"—… 就"，主句一般用过去完成时(h ad+V-ed)，从句用一般过去时，如果hardly,no sooner, scarcely放句首，主谓倒装。
3.Although he is considered a great writer,____(MET'91) A.his works are not widely read B.but his works are not widelyread C.however his works are not widely read D.still his works arenot widely read 选A.这是一个让步状语从句，主句与从句之间有一个从属连词 although(though)，不能再加but,howeve r,still等，但可以和yet连用。
4.No matter how hard he worked,____(84年) A.he could not do any better B.and he could not do any better C.so he could do any bettes D.but he could not do any better 选A.由no matter引导的让步状语从句，其主句也不能再用but,and,so 等并列连接词。
5.____he might,he failed,A.Try as B.As try C.Tried as D.As tried 选A.为了强调让步的意义，表示出非常强烈的对照，用as或though引导的让步状语从句，从句的语序要作部分调整，即把句子受强调的表语、状语或动词原形置于从句的句首。如果表语是单数可数名词，移置句首时，名词前不用冠词。如：
(1)Much as I like it,I will not buy it.(2)Child as she is,she knows a lot of English.
6.Did the two boys look so much alike____no one could tell thema part?
A.and B.that C.as D.so that

二、定语从句定语从句是在复合句中使其修饰的某一名词或代词代表一个(些)或一类特 定的人或东西。在做定语从句 的练习时，首先应该找出先行词，然后再确定选择关系代词或关系副词。能够引导定语从句的关系代词和关系副词有 who,whom,whose,that,which,when,why,where。
1.She heard a terrible noise,____brought her heart into ber mouth.(M
A.it B.which C.this D.that
选B.在非限定性定语从句中，关系代词用which不能用that。
2.He paid the boy $ 10 for washing ten wiondows,most of____hadn't cleaned for at least a y ear.(MET'90)
A.these B.those C.that D.which
选D.如果选A、B、C，整个句子不符合语法要求，因为有一个"逗号"， 不是并列句，因此只能是一 个非限定性定语从句，在非限定性定语从句中关系代词一般用which。
3.His parents wouldn't marry anyone____family was poor.(MET'88)

13.I still remember the day____I first came to Beijing.
A.which B.that C.when D.where
选C.先行词the day，在定语从句中作状语，所以选when。当先行词是时间名词或地点名词时，关系词选 用when或where,that或which，主要取决于在定语从句中所作成份，如果作宾语，用that或which，作状语用wh en或where。 如：
(1)I still remember the days that/which we spent in the countryside.
先行词是the days,spent是及物动词，that/which作spent的宾语。
(2)This is the place where I lived three years ago.
先行词是place,lived是不及物动词，where在从句中作状语。

15.I don't like the way____you laughed
at her.
A.which B.in that C.where D.that
选D.先行词是the way，表示方式，可用that(可省)或in which来引导一个定语从句。如果先行词是时 间或原因，也可用that(可省)或when或 why来引导定语从句。如：
(1)This was the reason that/why he was late yesterday.
(2)This is the last time that I shall give you a lesson.
