初中英語(yǔ)語(yǔ)法知識學(xué)習:否定句

  對人或事物加以否定的句子稱(chēng)為否定句。英語(yǔ)的否定句大都用not來(lái)表示否定,不同的句子又有不同的否定形式。

初中英語(yǔ)語(yǔ)法知識學(xué)習:否定句

  1.含有be的否定句

  如果句子中含有連系動(dòng)詞或助動(dòng)詞be,句子的否定形式在be的后面直接加not。如:

  He is not a student.他不是個(gè)學(xué)生。

  We are not in the school.我們沒(méi)在學(xué)校。

  I'm not good at English.我不擅長(cháng)英語(yǔ)。

  He was not late for school that day.那天他上學(xué)沒(méi)有遲到。

  They were not doing their homework at that time.那時(shí)他們不是在做作業(yè)。

  注意:

  在否定句中,be與not可以縮寫(xiě)。

  is not→isn't;are not→aren't;was not→wasn't;were not→weren't

  2.含有助動(dòng)詞will,shall,would,have,has,had的否定句

  如果句子中含有助動(dòng)詞will,shall,would,have,has,had等,則在這些助動(dòng)詞后面直接加not構成否定句。如:

  I have not been to the Great Wall.我沒(méi)有去過(guò)長(cháng)城。

  He has not finished his homework yet.他還沒(méi)有完成作業(yè)。

  They will not have a meeting next week.下周他們不舉行會(huì )議。

  We would not go there with them.我們不愿意和他們一起去那里。

  注意:

  在否定句中,助動(dòng)詞will,shall,would,have,has,had可與not縮寫(xiě)。

  will not→won't;shall not→shan't;would not→wouldn't;have not→haven't;has not→hasn't;had not→hadn't

  3.含有情態(tài)動(dòng)詞的否定句

  如果句子中含有情態(tài)動(dòng)詞can,may,must,need,could等,則在這些情態(tài)動(dòng)詞后直接加not構成否定句。如:

  We cannot speak French.我們不會(huì )說(shuō)法語(yǔ)。

  You must not put the bike here.你不能把自行車(chē)放在這里。

  They could not play computer games then.那時(shí)他們不會(huì )玩電腦游戲。

  You need not clean the room now.現在你不需要打掃房間。

  注意:

  在否定句中,情態(tài)動(dòng)詞與not可以縮寫(xiě)。

  cannot→can't;must not→mustn't;need not→needn't;could not→couldn't

  4.助動(dòng)詞do,does,did與not構成的否定句

  在一般現在時(shí)態(tài)和一般過(guò)去時(shí)態(tài)當中,如果句子的謂語(yǔ)是實(shí)義動(dòng)詞,那么其否定句就在實(shí)義動(dòng)詞前加do not;does not;did not。do not和does not用于一般現在時(shí)態(tài),does not只用于主語(yǔ)是第三人稱(chēng)單數的句子中;did not用于一般過(guò)去時(shí)態(tài)。do not可縮寫(xiě)為don't,does not可以縮寫(xiě)為doesn't,did not可縮寫(xiě)為didn't。如:

  They don't do housework at home.他們在家不做家務(wù)活。

  He doesn't go to school on weekends.他周末不上學(xué)。

  We didn't receive his letter.我們沒(méi)有收到他的來(lái)信。

  5.沒(méi)有not的否定句

  句子中如果有never,no,nothing,nobody,none,hardly,few,little,neither,too ...to ...等否定詞,則該句子被視為否定句。如:

  There are no desks or chairs in the room.房間里沒(méi)有課桌和椅子。

  Nothing in the world moves faster than light.世上沒(méi)有什么比光傳播得更快。

  I have few friends in this city.在這個(gè)城市我幾乎沒(méi)有朋友。

  He can hardly say an English word.他幾乎一個(gè)英語(yǔ)單詞也說(shuō)不出來(lái)。

  注意:

  句中含有否定詞構成否定句后,在反意疑問(wèn)句中要用肯定式。如:

  He has few friends here,does he?他這里幾乎沒(méi)有朋友,是不是?

  6.動(dòng)詞不定式的否定句

  動(dòng)詞不定式的否定句在動(dòng)詞不定式前直接加not。如:

  Mother asked me not to go out on Sunday.母親要求我星期天不要出去。

  They decided not to go there.他們決定不去那里了。

  注意:

  如果動(dòng)詞不定式是不帶to的不定式,在動(dòng)詞原形前加not。如:

  He made me not stay at home on weekend.他讓我周末不要呆在家里。

  7.had better的否定句

  had better是一個(gè)固定句型,意為“最好干某事”,其否定式在had better后直接加not。如:

  You'd better not go with me.你最好不要和我一起去。

  We'd better not play computer games.我們最好不要玩電腦游戲。

  8.祈使句的否定式

  祈使句的否定式在祈使句前直接加Don't。如:
