英語(yǔ)的復(fù)合句一般分為三大類型：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(fù)合句中起名詞作用，充當(dāng)主語(yǔ)、賓語(yǔ)、表語(yǔ)和同位語(yǔ)等的各種從句，統(tǒng)稱為名詞性從句。名詞性從句主要有以下幾種：
1. that 引導(dǎo)的從句
e.g. It is reported that one third of Guangzhou citizens planto buy a private car. (據(jù)報(bào)道，三分之一的廣州市民打算購(gòu)買私家車。)
2. whether/if 引導(dǎo)的從句
e.g. Whether motorcycles should be banned in Guangzhouhas become an issue of controversy.(廣州是否禁摩托車成了有爭(zhēng)議的話題。)
3. how/why/when/where引導(dǎo)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(dǎo)的從句
e.g. Who should be responsible for theenvironmental degradation is still unknown.(誰(shuí)對(duì)環(huán)境惡化負(fù)責(zé)還不清楚。)
形容詞性從句
具有形容詞功能，在復(fù)合句中做定語(yǔ)的從句被稱之為形容詞性從句或定語(yǔ)從句。被修飾的名詞、詞組或代詞被稱為先行詞。形容詞性從句分為兩種類型：
由關(guān)系代詞 who, whom, whose, that, which, as引導(dǎo)的從句。
例如：People who arestrongly against human cloning claim that it is immoral and unethical.(強(qiáng)烈反對(duì)克隆人的人們認(rèn)為這樣做不道德和不合倫理)
