全新英語語法·小學篇:二、陳述句的否定式

二、陳述句的否定式

表示否定意義的句子叫否定句，陳述句有兩種否定形式：

（一）在be動詞、助動詞 will/shall/should ...和情態(tài)動詞can，must ...后加not，便構(gòu)成否定結(jié)構(gòu)

I'm not playing with my pet dog.我沒有與我的寵物狗玩。

This isn't my T-shirt.Those aren't my trousers.這不是我的襯衫，那些不是我的褲子。

Tom wasn't on the playground.His friends weren't，either.湯姆不在操場上，他的朋友也不在那里。

I am busy tonight，so I won't go to the Christmas party with you.我今晚很忙，不能和你一起去圣誕晚會了。

You have an earache.You shouldn't listen to loud music.你耳朵疼，不能聽很響的音樂。

The crow can't drink the water，because the bottle is too long and thin.因為瓶子又長又細，烏鴉喝不到水。

Children mustn't play with fire.It's dangerous.孩子們不能玩火，因為很危險。

not和其他詞構(gòu)成的省略形式：

is not=isn't are not=aren't （am not沒有縮寫形式）

was not=wasn't were not=weren't

do not=don't does not=doesn't did not=didn't

have not=haven't has not=hasn't

will not=won't shall not=shan't can not=can't=cannot

must not=mustn't need not=needn't

（二）若謂語動詞為行為動詞，前面沒有助動詞或情態(tài)動詞時，在謂語動詞前加do not（一般現(xiàn)在時第三人稱單數(shù)加does not，一般過去時加did not）來構(gòu)成否定，動詞全部使用原形

They want to fly a kite.　否：They don't want to fly a kite.

Jack likes dancing.　否：Jack doesn't like dancing.

Tom cleaned his room yesterday.　否：Tom didn't clean his room yesterday.

注：have/has的否定式

（三）1.have/has的否定式

have/has表示“所有”時有兩種表達方法，have=have got，has=has got

I have a bicycle.=I have got a bicycle.

He has a ruler.=He has got a ruler.

但在表示否定句的時候：

I have a bicycle.　否：I don't have a bicycle.

I have got a bicycle.　否：I haven't got a bicycle.

He has a ruler.　否：He doesn't have a ruler.

He has got a ruler.　否：He hasn't got a ruler.

2.have/has不表示“有”，表示實意動詞的時候，構(gòu)成否定句時需要加助動詞（don't/doesn't）

I have an English class at 10：00.　否：I don't have an English class at 10：00.

Tom has a headache.　否：Tom doesn't have a headache.

They have tea in the garden.　否：They don't have tea in the garden.

The boy has a sandwich for breakfast.　否：The boy doesn't have a sandwich for breakfast.

（四）帶有否定意義的詞never，no，neither，nothing，nobody，none，few，little，hardly，seldom構(gòu)成的句子，本身已經(jīng)具有否定意義，不應再加否定詞

Tom never drinks milk.湯姆從來不喝牛奶。

Lucy hardly does exercises.Lucy幾乎不鍛煉。

Nobody is in the classroom.沒有人在教室里。

There is little water in the bottle.瓶子里有很少的水。

Neither of the my parents likes this movie.我父母都不喜歡這部電影。

（五）祈使句的否定形式見祈使句章節(jié)

（六）其他否定詞no，never，seldom，hardly也可構(gòu)成否定式。

I have no water.我沒有水。

I know nothing about it.我什么都不知道。

There are few students on the playground.操場上幾乎沒有學生。

He hardly drinks milk.他幾乎不喝牛奶。

Tips：

not any=no

I don't have any water.=I have no water.

He doesn't have any milk.=He has no milk.

There aren't any girls in the classroom.=There are no girls in the classroom.

I can't smell anything.=I smell nothing.

I didn't see anything in the dark.=I saw nothing in the dark.

（七）含有always，often，much，many等詞的肯定句變否定的時候，應將這些詞分別改成never，seldom，little，few，如：

He always asks Mum for money.　否：He never asks Mum for money.

It often snows here in winter.　否：It seldom snows here in winter.

I have much homework today.　否：I have little homework today.

Tips：

在否定句中，連接同等成分的連詞一般不用and，而用or；不能譯為“或”，而要譯成“也不”、“和”。

I don't have a pen or a pencil.我既沒有鋼筆也沒有鉛筆。

There is no air or water on the moon.月亮上既沒有空氣也沒有水。

Don't eat or drink on the underground.在地鐵上不要吃東西，也不要喝飲料。
