并列連詞的概念：
連詞是一種虛詞，它不能獨立擔(dān)任句子成分而只起連接詞與詞，短語與短語以及句與句的作用。連詞主要可分為兩類：并列連詞和從屬連詞。并列連詞用來連接平行的詞、詞組和分句。如：and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both...and, notonly...butalso, either...or, neither...nor, (and)then 等等。
并列連詞與并列結(jié)構(gòu)：
并列連詞引導(dǎo)兩個并列的句子。
1）and與or：
判斷改錯：
(錯) They sat down and talk about something.
(錯) They started to dance and sang.
(錯) I saw two men sitting behind and whisper there.
(對) They sat down and talked about something.
(對) They started to dance and sing.
(對) I saw two men sitting behind and whispering there.
解析：第一句：and連接兩個并列的謂語，所以talk應(yīng)改為talked。
第二句：and連接兩個并列的動詞不定式，第二個不定式往往省略to，因此sang應(yīng)改為sing。
第三句：and連接感觀動詞saw后面的用作的賓補(bǔ)的兩個并列分詞結(jié)構(gòu)，因此whisper應(yīng)改為whispering。
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）
如：Make up your mind, and you'll get the chance.=If you make up your mind, you'll get the chance.
One more effort, and you'll succeed.=If you make one more effort, you'll succeed.
2）both...and 兩者都
如：She plays(both) the piano and the guitar.
3）not only...but(also), as well as 不但…而且
如：She plays not only the piano, but(also) the guitar.
注意：not only…but also關(guān)聯(lián)兩個分句時，一個分句因有否定詞not而必須倒裝。
如：Not only does he like reading stories, but also he can even write some.
4）neither...nor 意思為“既不……也不……”謂語動詞采用就近原則，與nor后的詞保持一致。
如：Neither you nor he is to blame.
比較so和such ：
so與such的用法由不同詞性決定。such是形容詞，修飾名詞或名詞詞組，so是副詞，只能修飾形容詞或副詞。so還可與表示數(shù)量的形容詞many，few，much，little連用，形成固定搭配。
構(gòu)成：so+adj.
such+a(n)+n.
so+adj.+a(n)+n.
such+n.(pl.)
so+adj.+n.(pl.)
such+n.(pl.)
so+adj.+n.[不可數(shù)]
such+n.[不可數(shù)]
如：so foolish
such a fool
so nice a flower
such a nice flower
so many/few flowers
such nice flowers
so much/ little money.
such rapid progress
so many people
such a lot of people
注：so many 已成固定搭配，a lot of 雖相當(dāng)于many，但a lot of為名詞性的，只能用such搭配。 so...that與such...that之間的轉(zhuǎn)換既為so與such之間的轉(zhuǎn)換。
并列連詞用法點撥：
1、表示并列關(guān)系：
1）or意思為“否則”。
如：I must work hard, or I'll fail in the exam.
2）either...or意思為“或者……或者……”。注意謂語動詞采用就近原則。
如：Either you or I am right.
2、表示轉(zhuǎn)折或?qū)Ρ汝P(guān)系：
1）but表示轉(zhuǎn)折，while表示對比。
如：Some people love cats, while others hate them.
典型例題：
—Would you like to come to dinner tonight?
—I'd like to, ___ I'm too busy.
A. and
B. so
C. as
D. but
答案：D。but與前面形成轉(zhuǎn)折，符合語意。而表并列的and，結(jié)果的so，原因的as都不符合句意。
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。
如：They were not the bones of an animal, but(the bones) of a human being.
3、表示原因關(guān)系：
1）for 判斷改錯：
�。ㄥe）For he is ill, he is absent today.
�。▽Γ〩e is absent today, for he is ill. for是并列連詞，不能置于含兩個并列分句的句子的句首，只能將其放在兩個分句中間。
并列連詞知識體系：
比較and和or的用法：
1）并列結(jié)構(gòu)中，or通常用于否定句，and用于肯定句。
2）但有時and也可用于否定句。請注意其不同特點：
如：There is no air or water in the moon.
There is no air and no water on the moon.
在否定中并列結(jié)構(gòu)用or連接，但含有兩個否定詞的句子實際被看作是肯定結(jié)構(gòu)，因此要用and。
典型例題：
—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
答案：C。否定句中表并列用or,but表轉(zhuǎn)折。
判斷改錯：
�。ㄥe）We will die without air and water.
（錯）We can't live without air or water.
�。▽Γ￤e will die without air or water.
（對）We can't live without air and water.
