种类效用例句

1 .并列连词：连接处于并列关系的词

2 .从属连词：引导状语从句

连接代词和连接副词

主语从句

1 .并列连词引导两个并列句子1 ) and和or

判断错误：

(错误的) theysatdownandtalkaboutsomething。

(错误的) They started to dance and sang。

(错误的) isawtwomensittingbehindandwhisperthere。

(是的) theysatdownandtalkedaboutsomething。

(是的) They started to dance and sing。

( isawtwomensittingbehindandwhisperingthere。

分析：

第一句： talk必须更改为talked，因为and连接两个并行谓词。

第二句： and连接两个并列动词的不定式，第二个不定式多省略to，故sang应改为sing。

第三句：作为and连接感观动词saw之后宾补的两个并列分词结构。 因此，whisper应该变更为whispering。

注： and也可以与祈使句或名词短语连用来表示条件。

( or也有这个使用方法)

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

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

One more effort，and you'll succeed。

=If you make one more effort，you'll succeed。

2 ) both …and两者

sheplays(both ) the piano and the guitar。

3 ) notonly…but(also )，不仅是as well as ) )

She plays not only the piano，but(Also ) the guitar。

注意： not only… but also

关联两个从句时，一个从句有否定词not，所以必须倒装。

notonlydoeshelikereadingstories，but also he can even write some。

4 ) neithe…nor是“……也不是……”的意思

谓词采用邻近原则，与nor后面的词一致。

Neither you nor he is to blame。

2 .比较and和or1 )的并列结构，or通常用于否定句，and用于肯定句。

2 )但是，and有时也可以用在否定句中。

请注意其特征：

There is no air or water in the moon。

thereisnoairandnowateronthemoon。

在否定中，并列结构通过or连接，但包含两个否定词的句子实际上被视为肯定结构，所以使用and。

例题---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； 与

答案c。

把句子里的表并列起来，用or，but改变表。

判断错误：(错误) We will die without air and water。

(错误的) We can't live without air or water。

(是的) We will die without air or water。

(对) We can't live without air and water。

3 .表示选择的并行结构1 ) or意味着“否则”。

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

2 ) either…or是“或……或……”的意思。

注意谓语动词采用相近原则。

Either you or I am right。

4 .表示转折或对比：1) but表示转折，while表示对比。

Some people love cats，while others hate them。

例题的典型

--- wouldyouliketocometodinnertonight

--- I'd like to，___ I'm too busy。

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

答案d。

but与前转换，符合词义。

另一方面，表的排列的and、结果的so、原因的as都不符合文章内容。

2 ) not…but…是“不是……”的意思

not和but后面的术语应遵循一致的原则。

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

5 .表因关系

1 ) for

判断错误：

(错误的) For he is ill，he is absent today。

(没错) He is absent today，for he is ill。

for是并列连接词，不能位于包含两个并列分句的句子的开头。 只能放在两个分句之间。

2 ) so，therefore

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

注意：

a .两个并列连接词不能连用，但therefore、then、yet .可以与并列连接词连用。

You can watch TV，and or you can go to bed。

He hurt his leg，andso/andthereforehecouldn ' tplayinthegame。

b. although… yet…但是，although不与but连用。

(错误的) Although he was weak，but he tried his best to do the work .

(没错) Although he was weak，yet he tried his best to do the work。

6.so与suchsuch比较是形容词，修饰名词或名词短语。 so是副词，只能修饰形容词或副词。

o也可以与表示数量的形容词many、few、much、little连用，形成固定组合。

soadj.sucha(n ) n。

soadj.a(n ) n.suchn.( pl.) )。

soadj.n.(pl.) suchn.( pl.) )。

so adj. n. [不可数] such n. [不可数]

so foolish such a fool

so nice a flower such a nice flower

somany/fewflowerssuchniceflowers

somuch/little money.suchrapidprogress

so many people such a lot of people

so many已经成为固定的组合，a lot of相当于many，但a lot of是名词性的，只能用such组合。

so…that和such…that之间的变换是so和such之间的变换。

eg:the MP3 costme _ _ _ _ moneythaticouldn ' taffordtobuyit。

A .so much .B .such much C .so many

D . such many .(Key :A )

注意： too .so . that .such . that .enough . to .的交换。

so that to=in order to /that的用法。

Eg A .He is too young to go to school .

b.heis _ _ ayou ngboy _ _ _ _ he _ _ _ goto school。

c.heis _ _ young _ _ _ he _ _ _ goto school。

d.heisn ' t _ _ _ _ _ _ _ _ _ _ _ _ _ _ goto school。

( Keys :B :such，that，can't C :so，that，can't D : old，enough to )
