命题点一 并列复合句
知识必备 两个或两个以上的简单句用并列连词连在一起而构成的句子
叫做并列复合句。其基本结构是“简单句+并列连词+简单句”。并列
句中的各简单句意义同等重要,相互之间没有从属关系,是平行并列的
关系。
并列连词 作用 示例
and, not only...but also...,
neither...nor...等 表并列 She likes singing and she is
good at it.
but, yet, while, or(否
则,常用于祈使句)等 表转折 The twins study in the same
school, but they’re in different
classes.
并列连词 作用 示例
or, either...or...等 表选择 You can go to the museum by
bus or you can take a taxi.
so, for等 表因果 I have to look after my sister so
I can’t come to your party.

命题点二 主从复合句
知识必备 主从复合句是由一个主句和一个(或一个以上)的从句构成
的。主句作为句子的主体,从句充当句子的一个次要成分,不能独立成
为一个句子。
1. 宾语从句
在复合句中,由一个句子充当宾语,这个句子叫作宾语从句。基本
结构:主句+连接词+宾语从句。宾语从句的三要素:连接词、语序、
时态。
(1)连接词
连接词 用法 示例
that 本身无意义,一般情
况可省略 He said (that) he could
finish his work before
supper.
if,whether 意为“是否”,不作
句子成分,不可省略 She asked if/whether I
wanted a drink.
连接词 用法 示例
连接代词(what,which, who, whose,
whom) 在句中充当一定的句子成分,如主语、宾语、定语等 She was never satisfied
with what she had
achieved.
连接副词(when,
where, how, why) 在从句中作状语,如地点状语、时间状语等 He didn’t tell us where we
would see the dolphin
show.
(2)语序
宾语从句的语序是陈述语序,即“主句+连接词+从句(主语+谓语+
其他)”。如:
The teacher told us that science was interesting.老师告诉我们科学
很有趣。
She asked me whether/if I could swim. 她问我是否会游泳。
Can you tell me when the shop opens?你能告诉我商店什么时候开门吗?
【注意】
当连接词本身作宾语从句的主语时,后面直接加谓语动词。
I want to know what is the matter. 我想知道发生了什么。
I don’t know who will come tonight. 我不知道晚上谁会来。
(3)时态
主句时态 从句时态 示例
现在时态 根据实际情况而定 I don’t know when she will come
back.
过去时态 相应的过去时态 She told me that she was going to
Beijing the next week.
主句时态 从句时态 示例
任意时态 一般现在时(说明客
观事实、真理或自然
现象等) My geography teacher told us that the
earth goes around the sun.
宾语从句时态口诀:主现从随便,主过从必过,真理永一现。
1. 宾语从句由what, how, where等引导时可转换为“疑问词+动
词不定式”结构。如:
I don’t know how I can get to the movie theater.
=I don’t know how to get to the movie theater. 我不知道如何到达
电影院。
2. 宾语从句的否定转移。如果满足以下情况:①主句中的主语为第一人称(I/we);②谓语动词为think, believe, guess, expect, suppose等表示观念、信念、推测的词;③主句时态为一般现在时,常把宾语从句的否定词转移到主句中,即主句谓语动词为否定形式,宾语从句谓语动词为肯定形式。如:I don’t think he will help us. 我认为他不会帮助我们。
小试身手
用适当的连接词完成语篇。
Mrs.Haworth’s class required lots of attention. This was especially hard
for me because I was balancing a new school with a new part-time job. My
grades soon began to fall. Just as I began to get a D, Mrs.Haworth asked

2. my problem was. She listened to me and I knew she truly cared
about my life and my problem.

solve my problem on my own.And she would hand my paper over and
encourage me to deal with the ones I missed and find out 5. I hadn’t
worked them out. Thanks to her help, I made great progress and got an A in
the final exam.
that
how
why
2. 状语从句
在复合句中作状语的句子叫作状语从句。它可以出现在主句之前、
之后或中间,用连词引导,具有丰富的语义和语法功能,有助于表达复
杂的语言思想和逻辑关系。初中阶段常见的状语从句有:时间状语从
句、原因状语从句、条件状语从句、让步状语从句、目的状语从句、结
果状语从句等。
(1)时间状语从句

动词,表示某一时刻的动作 When we got to the mountain
top, it was raining hard.

句用过去进行时 The doorbell rang when I was
telephoning.
连词 用法 示例
while 从句的谓语动词通常为延续性动词 Judy ran to the garden while/when her parents were hiding the Easter eggs.
当主句和从句的时态都是进行时的时候,用while连接 Zhu Hui was watching the dragon boat races on TV while his mother was making zongzi in the kitchen.
as 侧重在某事发生的过程中另一件事发生 As the sun rose, the fog slowly disappeared.

时。如:The bus will not go till/until all the people get on it.直到所有的人都上了车,车才开走。
