一、 复合句的种类
英语的复合句一般分为三大类型：名词性从句、形容词性从句和副词性从句。
(一) 名词性从句
在整个复合句中起名词作用，充当主语、宾语、表语和同位语等的各种从句，统称为名词性从句。名词性从句主要有以下几种：
1. that 引导的从句 e.g. It is reported that one third of Guangzhou citizens planto buy a private car. (据报道，三分之一的广州市民打算购买私家车。)
2. whether/if 引导的从句 e.g. Whether motorcycles should be banned in Guangzhouhas become an issue of controversy.(广州是否禁摩托车成了有争议的话题。)
3. how/why/when/where引导的从句 e.g. This essay aims to explore why so manywhite collar workers suffer from insomnia. (本文将探讨为什么这么多白领失眠的原因。)
4. who/whom/whose/what/which引导的从句 e.g. Who should be respon sible for theenvironmental degradation is still unknown.(谁对环境恶化负责还不清楚。)
(二) 形容词性从句
具有形容词功能，在复合句中做定语的从句被称之为形容词性从句或定语从句。被修饰的名词、词组或代词被称为先行词。形容词性从句分为两种类型：
(1)由关系代词 who, whom, whose, that, which, as引导的从句。 例如: People who arestrongly against human cloning claim that it is immoral and unethical.(强烈反对克隆人的人们认为这样做不道德和不合伦理)
