连词

连词不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：

并列连词和从属连词。并列连词用来连接平行的词、词组和分句。如：and,but,or,nor,so,therefore,

yet,however,for,hence,aswellas,both…and,notonly…butalso,either…or,neither…

nor,（and）then等等。

20.1并列连词与并列结构

并列连词引导两个并列的词、词组或句子。

1）and与or

判断改错：（错）Theysatdownandtalkaboutsomething.

（错）Theystartedtodanceandsang.

（错）Isawtwomensittingbehindandwhisperthere.

（对）Theysatdownandtalkedaboutsomething.

（对）Theystartedtodanceandsing.

（对）Isawtwomensittingbehindandwhisperingthere.

解析：第一句：and连接两个并列的谓语，所以talk应改为talked。

第二句：and连接两个并列的动词不定式，第二个不定式往往省略to，因此sang应改为

sing。

第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因此whisper应

改为whispering。

注意：and还可以和祈使句或名词词组连用表示条件。（or也有此用法）例如：

Makeupyourmind,andyou'llgetthechance.拿定主意，这次你会有机会的。

=Ifyoumakeupyourmind,you'llgetthechance.

Onemoreeffort,andyou'llsucceed.再努力一下，你会成功的。

=Ifyoumakeonemoreeffort,you'llsucceed.

2）both…and两者都。例如：

Sheplays（both）thepianoandtheguitar.她弹钢琴，也弹吉他。

3）notonly…but（also）,aswellas不但…而且。例如：

Sheplaysnotonlythepiano,but（also）theguitar.她不但弹钢琴，也弹吉他。

注意：notonly…butalso关联两个分句时，一个分句因有否定词not而必须倒装。例如

Notonlydoeshelikereadingstories,butalsohecanevenwritesome.他不但喜欢

读小说，甚至还会写。

4）neithe…nor意思为"既不……也不……"谓语动词采用就近原则，与nor后的词保持一致。例如：

Neitheryounorheistoblame.你和他都不该受指责。

20.2比较and和or

1）并列结构中，or通常用于否定句，and用于肯定句。

2）但有时and也可用于否定句。请注意其不同特点：

Thereisnoairorwaterinthemoon.

Thereisnoairandnowateronthemoon.

在否定中并列结构用or连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

典型例题

---Idon'tlikechicken___fish.

---Idon'tlikechicken,___Ilikefishverymuch.

；；；；and

答案C。否定句中表并列用or,but表转折。

判断改错：（错）Wewilldiewithoutairandwater.

（错）Wecan'tlivewithoutairorwater.

（对）Wewilldiewithoutairorwater.

（对）Wecan'tlivewithoutairandwater.

20.3表示选择的并列结构

1）or意思为"否则"。例如：

Imustworkhard,orI'llfailintheexam.我要努力学习，否则考试要不及格了。

2）either…or意思为"或者……或者……"。注意谓语动词的主谓一致采用就近原则。例如：

EitheryouorIamright.不是你对，就是我对。

20.4表示转折或对比

1）but表示转折，while表示对比。例如：

Somepeoplelovecats,whileothershatethem.有些人喜欢猫，而有些人不喜欢。

典型例题

---Wouldyouliketocometodinnertonight?

---I'dliketo,___I'mtoobusy.

答案D。but与前面形成转折，符合语意。而表并列的and，结果的so，原因的as都不符合句意。

2）not…but…意思为"不是…而是…"，后面的用词要遵循一致原则。

Theywerenotthebonesofananimal,but（thebones）ofahumanbeing.这些不是动物的

骨头，而是人的。

20.5表原因关系

1）for是并列连词，不能置于含两个并列分句的句子的句首，只能将其放在两个分句中间。

判断改错：（错）Forheisill,heisabsenttoday.

（对）Heisabsenttoday,forheisill.

2）so为连词,therefore一般为副词。例如：

Hehurthisleg,sohecouldn'tplayinthegame.他的腿受伤了，不能上场。

Ithink;thereforeIexist.我思故我在。

20.6比较so和such

such是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。so还可与表示数量的形容词

many，few，much，little连用，形成固定搭配。

so++a（n）+n.

so+adj.+a（n）++n.（pl.）

so+adj.+n.（pl.）such+n.（pl.）

so+adj.+n.（不可数）such+n.（不可数）

sofoolishsuchafool

soniceaflowersuchaniceflower

somany/fewflowerssuchniceflowers

somuch/pidprogress

somanypeoplesuchalotofpeople

somany已成固定搭配，alotof虽相当于many，但alotof为名词性的，只能用such搭配。so…

that与such…that之间的转换即为so与such之间的转换。
