連接詞是英語中的一個重要組成部分,它們連接英語的句子和段落,使文章流暢自然,使英語句子與句子之間,段落與段落之間的關(guān)系一目了然。英語中連接詞分為兩大類:連詞性連接詞(即連詞)和副詞性連接詞。接下來跟小編一起來看看吧。 一、連詞性連接詞(連詞) 連詞用來連接詞與詞、短語與短語或句子與句子。連詞不能單獨(dú)作句子成分,也沒有詞形變化。連詞分為并列連詞和從屬連詞兩種。 (一)并列連詞 并列連詞用來連接句子中擔(dān)任相同成分的詞、短語或分句。常見的有七個單詞和四個短語:and, but, or, for(因?yàn)?, nor, so, yet; both…and…, not only….but also…., either…or…., neither…nor 1. and用來連接詞、短語或分句,表示并列或?qū)ΨQ關(guān)系: The man put on his coat and hat, and went out of the office. 那個人穿上外衣、戴上帽子,走出了辦公室。 A car and a dictionary are both useful. 汽車和字典都有用處。 I went home and John stayed there. 我回家了,而約翰呆在那里。 2. but連接兩個含義不同甚至相反的詞、短語或分句,表示轉(zhuǎn)折: Not everybody is honest and hardworking, but Tom is. 并非每個人都跟湯姆一樣誠實(shí)肯干。 We tried to persuade her to do it but failed. 我們嘗試去說服她,但沒有成功。 3. or表示兩者居其一,表示選擇: Which VCD player is better, this one or that one? 哪個VCD更好,這個還是那個? Are you hungry or not? 你餓了沒有? 4 .for(因?yàn)?只能放在表示結(jié)過的分句后面,引導(dǎo)表示原因的分句: I must be going, for it’s getting dark. 我必須走了,因?yàn)樘旌诹恕?#13; He didn’t go there, for he was ill. 他沒到那兒去,因?yàn)樗×恕?#13; 5. both…and…只能用來連接兩個并列的詞或短語,不能連接句子: His plan is both easy and practical. 他的計(jì)劃既容易又實(shí)用。 Zhang Yimou is a famous director both at home and abroad. 張藝謀是一位在國內(nèi)外都著名的導(dǎo)演。 Both this plane and its engines are made in China. 這架飛機(jī)的機(jī)身和發(fā)動機(jī)都是制造的。 6. not only…but also…不但能連接詞和短語,而且還能連接分句,also 有時省略(注意not only 位于句首時,主語和謂語需要倒裝): He is not only an actor but also a writer. 他不僅是演員,而且是作家。 He not only read it but also remembered what he had read. 他不但讀過,而且記住了所有讀過的東西。 Not only did he say it but (also) he did it. 他不但說了,而且做了。(倒裝) Not only do the nurses want a pay rise, but also they want reduced hours. 護(hù)士們不但要求加工資,而且還要求縮短工時。(倒裝) 7. either…or…表示選擇,“或者…或者…”、“不是….就是…”的意思(注意either…or…整個結(jié)構(gòu)作主語時句子中的動詞通常要和鄰近的主語相一致): Either you are wrong, or I am. 不是你錯了,就是我錯了。 Either you or he is going to get the job. 不是你就是他將獲得這份工作。 Can I borrow either your car or your bike? 我可以借用你的汽車或者自行車嗎?

He asked me if/whether I knew John. 他問我是否認(rèn)識約翰。 此外,that, which, who, whom, whose, when, why, where等還可以引導(dǎo)定語從句。 2. 連詞when, while, before, after, till/until, since, as soon as等引導(dǎo)時間狀語從句: She said hello to me when she saw me. 她看到我的時候,和我打了招呼。 I’ll wait here until you come back. 我將在這里等你回來。 3. 連詞if, unless引導(dǎo)條件狀語從句;because, as, since引導(dǎo)原因狀語從句: I’ll help her if she asks me to. 如果她要求我,我就幫助她。 I won’t help her unless she asks me to. 除非她要求我,否則我不會幫她。 He didn’t come because he was ill. 因?yàn)樗×?,所以沒來。 As he hasn’t appeared yet, we shall start without him. 既然他還沒有出現(xiàn),我們就先開始吧。 Since everybody is here, let’s begin. 既然大家都到了,咱們就開始吧。 4. 連詞in order than, so that引導(dǎo)目的狀語從句;so…that…引導(dǎo)結(jié)果狀語從句: I locked the door in order that we might continue our discussions undisturbed. (=I locked the door in order to continue our discussions undisturbed.) 我把門鎖上了,以便我們可以繼續(xù)討論而不受打擾。 The car ran so fast that I couldn’t see who was in it. 汽車跑得那么快,我沒看清誰坐在里面。 5. 連詞than, as…as…, not as/so…as…用來引導(dǎo)比較狀語從句: He is better educated than his brother. 他比他兄弟受的教育好。 He is as well educated as his brother. 他和他兄弟受的教育一樣好。 He is not as/so well educated as his brother. 他沒有他兄弟受的教育好。 6. 連詞although, though 引導(dǎo)讓步狀語從句;where, wherever 引導(dǎo)地點(diǎn)狀語從句: I’ll go wherever you go. 不管你去哪兒,我就去那兒。 Though/Although she is rich, she’s not happy. 盡管她富有,但她并不幸福。
Stay where you are! 原地別動! 一般來說,連詞性質(zhì)的連接詞連接兩個分句或引導(dǎo)一個從句,兩個分句或主從復(fù)合句之間用逗號連接。 二、副詞性連接詞 副詞性質(zhì)的連接詞不能象連詞一樣分句或主從復(fù)合句之間用逗號連接。也就是說它們不能連接兩個分句或引導(dǎo)從句。它們引導(dǎo)的句子與前面的句子之間要用分號或句號,而它們與引導(dǎo)的句子之間往往用逗號。副詞性質(zhì)的連接詞在寫作中常常使用,主要分為以下幾類: 1. 表示順序的,如first, in the first place, then, finally, in the end等等,尤其要注意then: 誤:He graduated from college in 2003, then he found a job. 正:He graduated from college in 2003. Then he found a job.(=He graduated from college in 2003, and then he found a job.) 2. 表示遞進(jìn)關(guān)系的,如in addition, what is more, furthermore, moreover等。注意in addition 與in addition to 的區(qū)別:in addition 是副詞性質(zhì);而in addition to 是介詞性質(zhì),后面必須接賓語 3. 表示轉(zhuǎn)折關(guān)系的,如 however, nevertheless, nonetheless, on the contrary, in contrast, 等等。要注意不要把however 當(dāng)成連詞: 誤:In 2003, the United States launched the war on Iraq on account of Iraq possessing weapons of mass destruction (WMD), however, no WMD has been found in Iraq so far. 正:In 2003, the United States launched the war on Iraq on account of Iraq possessing weapons of mass destruction (WMD). However, no WMD has been found in Iraq sofar.
