英語(yǔ)的復合句一般分為三大類(lèi)型：名詞性從句、形容詞性從句和副詞性從句。
名詞性從句
在整個(gè)復合句中起名詞作用，充當主語(yǔ)、賓語(yǔ)、表語(yǔ)和同位語(yǔ)等的各種從句，統稱(chēng)為名詞性從句。名詞性從句主要有以下幾種：
1. that 引導的從句
e.g. It is reported that one third of Guangzhou citizens planto buy a private car. (據報道，三分之一的廣州市民打算購買(mǎi)私家車(chē)。)
2. whether/if 引導的從句
e.g. Whether motorcycles should be banned in Guangzhouhas become an issue of controversy.(廣州是否禁摩托車(chē)成了有爭議的話(huà)題。)
3. how/why/when/where引導的從句
e.g. This essay aims to explore why so manywhite collar workers suffer from insomnia. (本文將探討為什么這么多白領(lǐng)失眠的原因。)
4. who/whom/whose/what/which引導的從句
e.g. Who should be responsible for theenvironmental degradation is still unknown.(誰(shuí)對環(huán)境惡化負責還不清楚。)
形容詞性從句
具有形容詞功能，在復合句中做定語(yǔ)的從句被稱(chēng)之為形容詞性從句或定語(yǔ)從句。被修飾的名詞、詞組或代詞被稱(chēng)為先行詞。形容詞性從句分為兩種類(lèi)型：
由關(guān)系代詞 who, whom, whose, that, which, as引導的從句。
例如：People who arestrongly against human cloning claim that it is immoral and unethical.(強烈反對克隆人的人們認為這樣做不道德和不合倫理)
