并列句，复合句和连词命题规律：并列句和复合句以及连词是中考的重点内容，也是中考的必考题。
期中复合句考察的内容涉及状语从句，宾语从句，定语从句中引导词的运用命题趋势：宾语从句，连词的使用，定语从句的引导词一、并列句用并列连词连接起来的两个或两个以上的简单句叫做并列句。
1. 构成：简单句+ 并列连词+ 简单句2. 常见的用于连接两个简单句的并列连词有：and，but，or，so，for。
（1）and意为“和，并且”，表示顺延、并列等关系。
如：Work hard and you can pass the exam.= If you work hard, you can pass the exam.（2）but意为“但是”表示转折关系。
如：He is rich but he is not happy.（3）or意为“否则，或者，或“表示选择关系。
如：Hurry up, or you’ll be late.=If you don’t hurry up, you’ll be late.（4）so意为“所以，因此，于是”表示因果关系。
如：Kate was i ll so she didn’t go to school.（5）for意为“因为”，表示因果关系。
如：I have to stay up late, for I have a lot of work to do.3. 当连词and连接的并列句前半部分是祈使句，后半部分是将来时的陈述句时，其含义相当于由if引导的条件状语从句。
这种句型还可以用or来连接，但意思不同。
如：Think it over, and you’ll find the answer.=If you think it over, you’ll find the answer.4. 其他的并列句其他的并列连词有then，while，when，yet，not only…but also…, neither…nor…, either…or…, both…and…, as well as。
如：I like English while my brother likes Chinese.二、状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等，状语从句由从属连词引导，与主句连接，位于句首时，常用逗号与主句分开，位于句末时，其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、原因状语从句、结果状语从句、条件状语从句、让步状语从句、方式状语从句、目的状语从句等。
的词叫做先行词，通常位于定语从句之前。
引导定语从句的是关系代词that，which，who （whom，whose）和关系副词when，where，why。
关系代词或关系副词位于先行词和定语从句之间，它既起连接作用，又充当从句中的一个成分。
含定语从句的复合句的基本结构为：先行词+ 关系词+ 定语从句1. 关系代词的用法一般情况下，that既可指人又可指物，可以代替who，whom和which，在从句中作主语或谓语动词的宾语，但不能作介词的宾语；which指物，在从句中作主语或谓语动词的宾语；who在从句中作主语；whom在从句中作宾语；whose在从句中作定语；where在从句中通常修饰表示地点的名词，作地点状语；when在从句中通常修饰表示时间的名词，作时间状语；why在从句中作原因状语，先行词通常是reason，有时why也可用“for + which”代替。
（1）下列情况下，只能用that引导，不能用who或which引导：1）当先行词是all，little，much，none，everything，anything，nothing等代词时。
如：❝Is there anything (that) you don’t understand?Tom told her mother all that had happened.2）当先行词前面有the only，the very，the last等修饰时。
如：❝He is the only person that can help you out.（当先行词是人时，也可用关系代词who，whom引导。
）3）当序数词或形容词最高级修饰先行词时。
如：❝This is the best book that I have ever read.4）当先行词前面有only，all，any，no等修饰时。
如：I want to read all the books that were written by Lu Xun.5）当主句是以疑问词who或which开头的特殊疑问句时。
如：❝Who is the boy that is playing football?（2）关系代词的省略。
一般情况下that，which，whom可以省略，但以下情况不能省略：1）关系代词that在从句中作介词的宾语时，不能省略，而且介词不能放在that前面，只能放在从句中有关动词的后面。
如：❝The woman that she talks with is her teacher.2）关系代词which，whom在从句中作介词宾语时，不能省略。
介词可以放在which，whom 之前，也可以放在从句中有关动词的后面，以使关系代词紧跟它所修饰的先行词。
如：❝I’ll never forget the day on which I joined the club.3）that，which，who在从句中作主语时，不能省略。
如：❝Who is the boy that is talking with our teacher?7.【2011湖南湘潭】23.______Zhai Xiaowei has only one leg, he can dance wonderfullyA .Though B.But C.
