复合句
一、状语从句(修饰主句动作, 表时间、条件等)
状语从句需用引导词连接, 关键规则: 若主句是一
般将来时, 从句用一般现在时表将来(即“主将从
现”)。
1. 时间状语从句(表“何时做”, 记引导词+用法)
引导词 含义 用法
when 当……时 从句动作可“延续”可“瞬
间”
while 与……同
时; 在……
期间 从句动作必须“延续”(常与
进行时连用)
引导词 含义 用法
as soon as 一……
就…… 严格遵循“主将从现”
引导词 含义 用法
before/after 在……之前/
之后 after 从句遵循“主将从
现”;
before 从句若表“过去完
成”, 主句用过去完成时
引导词 含义 用法
until/till 直到……
才…… 主句动作“延续”: 直接用
until;
主句动作“瞬间”: 用not ...
until
since 自从……以
来 主句用现在完成时, 从句用
一般过去时
2. 条件状语从句(表“在什么条件下做”)
引导
词 含义 规则 (主将从现) 示例
if 如果 主句将来时/
祈使句/情态
句, 从句现
在时 If you ask him, he will help
you.

引导

as

as 只要 同上, 表

书。
【拓展】条件句变祈使句
“if 从句+主句”可改为“祈使句+and/or+陈述句”:
e.g. ①If you get up early, you can catch the bus.
→Get up early, and you can catch the bus. 如果你早点起
床, 就能赶上公交。
②If you don’t hurry, you’ll be late.→Hurry up, or you’ll
be late. 快点, 否则你会迟到。
二、宾语从句(作主句的宾语, 即动作的对象是一个句
子)
常接宾语从句的动词有say, tell, think, know,
hope; 常接宾语从句的形容词有afraid, sure, glad,
sorry(如 I’m sure that ...)。

实、普遍真理
或引用格言、
谚语 一般现在时 The teacher told us that

the sun.老师告诉我们地
球绕着太阳转。
3. 语序: 在含有宾语从句的复合句中, 不管充当宾语从
句的句子原来是什么语序, 构成宾语从句时一定要用
陈述语序。
4. 宾语从句的否定前移: 当主句是一般现在时, 谓语是
think, guess, suppose, believe等动词, 且主语为第
一人称时, 从句若表示否定, 一般要将否定词not转
移到主句的谓语之前。
e.g. I don’t think this coat really suits me. 我觉得这件
大衣不大适合我穿。
三、定语从句(见第一部分第148页)
四、并列复合句
由两个简单句并列组成, 简单句相互间没有从属关
系, 意义同等重要。
基本结构: 简单句+并列连词+简单句。(两个句子
地位平等)
