連詞是一種虛詞，起連接詞與詞，短語(yǔ)與短語(yǔ)以及句與句的作用。

并列連詞（注意：從屬連詞放在從句中學(xué)習(xí)）

1)and 與or

They sat down and talked about something.

I saw two men sitting behind and whispering there.

He can’t sing or dance.

注意：and 還可以和祈使句或名詞詞組連用表示條件。（or也有此用法）

 Make up your mind, and you''ll get the chance.

= If you make up your mind, you''ll get the chance.

 One more effort, or you''ll never succeed.

= If you don’t make one more effort, you''ll never succeed.

2)  both …and… 兩者都

She plays (both) the piano and the guitar.

3) not only…but (also), as well as  不但…而且

She plays not only the piano, but (also) the guitar.

注意： not only… but also 關(guān)聯(lián)兩個(gè)分句時(shí)，一個(gè)分句因有否定詞not 而必須倒裝。

 Not only does he like reading stories, but also he can even write some.

4) neither…nor… 意思為 “既不……也不……” 謂語(yǔ)動(dòng)詞采用就近原則，與nor后的詞保持一致。

Neither you nor he is to blame.

表示選擇的并列結(jié)構(gòu)

1) or意思為"否則"。

 I must work hard, or I''ll fail in the exam.

2) either…or意思為"或者……或者……"。注意謂語(yǔ)動(dòng)詞采用就近原則。

 Either you or I am right.

表示轉(zhuǎn)折或?qū)Ρ?/strong>

1) but表示轉(zhuǎn)折，while表示對(duì)比。

 Some people love cats, while others hate them.

2)  not…but… 意思為"不是……而是……"

 not 和but 后面的用詞要遵循一致原則。

 They were not the bones of an animal, but (the bones) of a human being.

 表原因關(guān)系

1) for

for是并列連詞，不能置于含兩個(gè)并列分句的句子的句首，只能將其放在兩個(gè)分句中間。

 He is absent today, for he is ill.

2) so, therefore

He hurt his leg, so he couldn''t play in the game.

注意：

a. 兩個(gè)并列連詞不能連用，但therefore, then, yet.可以和并列連詞連用。

He hurt his leg, and so / and therefore he couldn''t play in the game.

b. although… yet…，但although不與 but連用。

Although he was weak, yet he tried his best to do the work.

1.and 和 or 前面是祈使句或省略的祈使句；2.結(jié)合上下文靈活運(yùn)用連詞

【典型例題】

1.---I don''t like chicken ___ fish.

---I don''t like chicken, ___ I like fish very much.

A. and; and B. and; but C. or；but D. or；and

解析：錯(cuò)選B。否定句中表并列用or, but 表轉(zhuǎn)折，答案C。

2. --- Would you like to come to dinner tonight?

--- We''d like to, but _____ my wife _____I am free then.

1. both, and  B. neither, nor  C. 不填，and  D. not, or

解析：錯(cuò)選D。根據(jù)題意，應(yīng)該是“可是我和我妻子那時(shí)都沒(méi)時(shí)間?！睘閮烧叩娜糠穸ǎ瑧?yīng)該用neither, nor, 故正確答案為B。

3.I hope you don’t mind my asking, ______ where did you buy this pair of shoes?

A. and B. but C. or D. so

解析：錯(cuò)選A。此題屬于靈活運(yùn)用，前后句轉(zhuǎn)折的意思很微妙，正確答案為B；此題與I’ m sorry, but can I ask you a private question? 同。
