連詞連接兩個(gè)詞、短語(yǔ)或句子，從句法的意義上說，連詞是使語(yǔ)句豐富多彩不可或缺的詞。

　　例一 Between the two generations, it is often not their age, ___ their education that causes misunderstanding.

　　A. like B. as

　　C. or D. but

　　答案D。not …but…連接age和education兩個(gè)單詞。

　　例二 Reality is not the way you wish things to be, nor the way they appear to be, ____ the way they actually are.

　　A. as B. or

　　C. but D. and

　　答案C。題干中not…nor…，but…連接三個(gè)the way…短語(yǔ)。

　　例三They wanted to charge $ 5, 000 for the car , ______ we managed to bring the price down.

　　A．but B．so

　　C．when D．since

　　答案A。but連接前后兩個(gè)有轉(zhuǎn)折關(guān)系的單句。

　　掌握連詞要注意如下幾個(gè)方面：

　　一、連詞要分類記憶

　　連詞數(shù)量不是很多，但其語(yǔ)義覆蓋到了各種邏輯關(guān)系。記憶連詞可以采取分類記憶的辦法，將連詞按形式、來源和語(yǔ)法功能進(jìn)行分組記憶。

　　1. 連詞從形式上說，有單個(gè)使用的詞，如and，since等；有成對(duì)使用的詞，如not only…but also，as…as等；還有兩個(gè)以上的詞組合而成的短語(yǔ)連詞，如as well as，in order that等。

　　例一 A man cannot smile like a child, _____a child smiles with his eyes, while a man smiles with his lips alone.

　　A. so B. but

　　C. and D. for

　　答案D。for為并列連詞，表示因果。

　　例二 you have mentioned it，I’ll remember to look after your dog when you go traveling．

　　A．Before B．If

　　C．Now that D．Until

　　答案C。Now that為從屬連詞，表示原因。

　　例三 ____I can see , there is only one possible way to keep away from danger.

　　A. As long as B. As far as

　　C. Just as D. Even if

　　答案B。as far as意為“據(jù)……”， “就……”，表示程度、深度等。

　　2. 連詞從來源上說，有本身就是連詞的，如and，or等；有一詞多“性”的詞，如yet，immediately等，除了做副詞之外，它們也有連詞的用法，在做題時(shí)需要留心辨別；還有從動(dòng)詞的分詞轉(zhuǎn)化而來的分詞連詞，如provided，supposing，considering等。

　　例一We called the First - Aid Center_______ the traffic accident happened.

　　A. immediately

　　B. shortly

　　C. quickly

　　D. hurriedly

　　答案A。immediately在這里做連詞，相當(dāng)于as soon as的用法，表示：“…立即就…”。

　　例二She came to the scene ______ she heard of the accident.

　　A．a(chǎn)t the moment

　　B．the moment

　　C．for the moment

　　D．in a moment

　　答案B。the moment在這里做連詞，相當(dāng)于as soon as的用法，表示：“…即刻就…”。注意，在使用時(shí)the moment前不加介詞，后不加連詞，不能錯(cuò)誤地表述為“at the moment when”

　　例三 _____the pain was bad, ______he did not complain.

　　A. Although; but

　　B. Though; but

　　C. Though; yet

　　D. Even; still

　　答案C。Although /Though和but都是連詞，在一個(gè)句子中，只能使用一個(gè)，不可同時(shí)使用。這里的yet充當(dāng)副詞。同樣的道理，because和so，一“因”一“果”，也不能同時(shí)在一個(gè)句子中使用。

　　3. 連詞從語(yǔ)法作用上說，有并列連詞，即連接并列的詞、短語(yǔ)或句子，表示并列、遞進(jìn)、轉(zhuǎn)折、因果、選擇等等，如and, but, or, nor, so, therefore, yet, however, nevertheless, for, as well as, both…and…, not only…but also…, either…or…, neither…nor…, and then等；

　　例一Stand over there you’ll be able to see it better.

　　A. or B. while

　　C. but D. and

　　答案D。and表示遞進(jìn)。

　　例二 You have failed two tests. You’d better start working harder, ____you won’t pass the course.

　　A. and B. so

　　C. but D. or

　　答案D。or引出結(jié)果。

　　例三—— I think George doesn’t really care for TV plays.

　　——Right, he still watches the program.

　　A. and B. but

　　C. or D. so

　　答案B。but表示轉(zhuǎn)折。

　　例四Unlike watching TV, reading is a highly active process ______ it requires attention as well as memory and imagination.

　　A. until B. but

　　C. unless D. for

　　答案D。for表示因果。

　　連詞還有從屬連詞，即連接復(fù)合句中的主句及從句。其中：

　�。�1） 引導(dǎo)名詞性從句的連詞有：
