如何用復(fù)合句寫出漂亮的雅思作文
英語的復(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。
(一)名詞性從句
在整個(gè)復(fù)合句中起名詞作用，充當(dāng)主語、賓語、表語和同位語等的各種從句，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 plan to buy a private car. (據(jù)報(bào)道，三分之一的廣州市民打算購買私家車。)
2. whether/if引導(dǎo)的從句e.g. Whether motorcycles should be banned in Guangzhou has 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 many white 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 the environmental degradation is still unknown。(誰對(duì)環(huán)境惡化負(fù)責(zé)還不清楚。)
(二)形容詞性從句
具有形容詞功能，在復(fù)合句中做定語的從句被稱之為形容詞性從句或定語從句。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：
(1)由關(guān)系代詞who, whom, whose, that, which, as引導(dǎo)的從句。例如： People who are strongly 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)
(2)由關(guān)系副詞when, where, why引導(dǎo)的從句。例如： I would like to analyze the reasons why a growing number of teenagers are addicted to gambling。(我將分析為什么越來越多的青少年沉迷于賭博的原因。)
(三)副詞性從句
副詞性從句也稱為狀語從句，主要用來修飾主句或者主句的謂語。大致分為九大類，分別表示時(shí)間、地點(diǎn)、原因、目的、結(jié)果、條件、讓步、比較和方式。
(1)時(shí)間狀語從句e.g. When everyone is fully aware of the severity of fresh water scarcity and takes effective measures, I am convinced that we will tackle this problem constructively。(當(dāng)每個(gè)人充分意識(shí)到淡水短缺的嚴(yán)重性，并采取有效措施，我相信我們一定能妥善解決好這個(gè)問題。)
(2)地點(diǎn)狀語從句e.g. Where there is smoke, there is fire。(無風(fēng)不起浪)(3)原因狀語從句e.g. Pets should be forbidden because they may spread diseases and damage the cityscape。(應(yīng)該禁止飼養(yǎng)寵物，因?yàn)樗鼈兛赡軙?huì)傳播疾病和有損市容。)
(4)目的狀語從句e.g. Old people should be encouraged to live in a nursing house so that they can enjoy professional care and first-rate facilities. (應(yīng)當(dāng)鼓勵(lì)老人到敬老院居住，這樣他們可以享受到專業(yè)的照料和一流的設(shè)施。)
(5)結(jié)果狀語從句e.g. Some government officials fail to recognize the potential hazards of improper waste disposal, so that the environment in some cities is deteriorating。(一些政府官員未能認(rèn)識(shí)到垃圾處理不當(dāng)帶來的潛在危害，因此一些城市的環(huán)境不斷惡化。)
(6)條件狀語從句e.g. If we continue to overlook the increasing waste in Guangzhou, it is likely that Guangzhou will become a huge landfill site sooner or later。(如果我們繼續(xù)無視廣州日益增多的垃圾，有可能不久的將來廣州將成為巨大的垃圾填埋場(chǎng)。)
(7)讓步狀語從句e.g. While I admit that smoking has some side-effects, I still feel that it is ridiculous to ban smoking in public places。(雖然我承認(rèn)吸煙有副作用，我依然覺得公共場(chǎng)所禁煙是荒唐的。)
(8)比較狀語從句e.g. Red is two times as much as Blue。(紅色是藍(lán)色的兩倍。)
(9)方式狀語從句e.g. Just as we protect less able human beings, so we should safeguard the welfare of other weaker species。(正如我們保護(hù)弱者一樣，我們也應(yīng)該保護(hù)弱勢(shì)物種的福利。)
