英文句子種類辨析之肯定句和否定句

  例:Mr. Walker is an Englishman.

 。ㄈA克先生是英國(guó)人。——肯定句)

  例:He is not an American.

 。ㄋ皇敲绹(guó)人!穸ň洌

  簡(jiǎn)單地說(shuō),表達(dá)事物的“Yes”這一面的句子就是肯定句,“No”的一面的就叫做否定句。

  傳統(tǒng)的'英語(yǔ)入門都是先學(xué)肯定句,然后再學(xué)肯定句的反面,亦就是否定句。否定句的表達(dá)方式基本上有下面的兩種。

  (1)使用副詞否定詞“not”,例如:

  (a)be,have為主要?jiǎng)釉~:

  例:I am not a good swimmer.

 。ㄎ也皇且粋(gè)游泳的好手。)

  例:He was not at home yesterday afternoon.

 。ㄗ蛱煜挛缢辉诩摇#

  例:I have not much money.

 。ㄎ覜]有很多錢。)

  例:He has not many friend here.

 。ㄔ谶@里他沒有很多朋友。)

  解說(shuō)“be/have +not”?s短成一詞,尤其是日常談話更是如此。例如:

  例:You aren't [a:nt] a friend of his, are you ?

 。悴皇撬呐笥寻桑遣皇?)

  例:He isn't [>!znt] my brother.

 。ㄋ皇俏业男值堋#

  例:I wasn't [>w&znt] there at that time.

 。ó(dāng)時(shí)我沒有在那兒。)

  例:There weren't [w+:nt] many people at the party yesterday.

 。ㄗ蛱鞗]有很多人參加宴會(huì)。)

  “am +not”不是“amn't”,而是“aren't”或“ain't[eint]”,例如:

  例:I ain't ready.

 。ㄎ疫沒準(zhǔn)備好。)

  例:I am very nice to you, aren't I?

 。ㄎ覍(duì)你很不錯(cuò),是不是?)

  美國(guó)人用“ain't”很隨便,應(yīng)該是“are not,is not,have not,has not”的地方,他們也會(huì)“ain't”一下就帶過(guò)去,宜注意。

  下面例句是“have not,has not”的縮短形。

  例:I haven't[>h$vnt] a headache.

 。ㄎ覜]有頭痛。)

  例:He hasn't[>h$znt] come yet.

  (他還沒來(lái)。)

  (b)be,have為助動(dòng)詞

  例:You aren't going to go to her birthday party, are you?

 。悴淮蛩銋⒓铀纳昭鐣(huì),是不是?)

  例:It isn't raining outside.

  (外面沒有在下雨。)

  例:She wasn't asked to speak at the meeting.

 。ㄋ龥]有被請(qǐng)求在會(huì)上講話。)

  例:I haven't done anything wrong to her.

 。ㄋ麤]有做對(duì)不起她的事。)

  例:He hasn't yet paid the money.

 。ㄋ形锤跺X。)

  be+ V -ing(進(jìn)行時(shí)),be +P.P.(過(guò)去分詞)(被動(dòng)詞態(tài)),have(has,had)+P.P.(完成時(shí))等的“be,have(has,had)”皆為助動(dòng)詞。例1的“be going to …”在學(xué)校文法中也常被視為助動(dòng)詞。

  (c)“助動(dòng)詞+V”時(shí)

  動(dòng)詞帶有助動(dòng)詞“will,shall,can,may,must,need,dare,ought to,used to,had better”等時(shí),將“not”置于助動(dòng)詞與主要?jiǎng)釉~之間。例如:

  例:I will not do it again.

  I won't[wount] do it again.

 。ㄎ也辉敢庠僮鲞@種事。)

  例:The old man cannot find his way home.

  (那個(gè)老人找不到回家的路。)

  例:I couldn't sleep last night.

 。ㄗ蛞刮覠o(wú)法入睡。)

  例:You ought not to swim in the river.

 。悴粦(yīng)該在河里游泳。)

  例:You had better not tell her everything.

 。阕詈貌灰獦訕邮虑槎几嬖V她。)

  注:“can”的否定形式是“cannot or can't”,不可寫成“can not or cann't”。

  (d)使用助動(dòng)詞“do”的否定句

  一般動(dòng)詞的否定句通常使用助動(dòng)詞“do”,句式如下:

  句型 do(does, did)+not + V(原形動(dòng)詞)

  例:I don't know her very well.

  (我并不很了解她。)

  例:He doesn't like Chinese tea very much.

 。ㄋ⒉缓芟矚g中國(guó)茶。)

  例:She didn't come to school this morning.

 。ń裉煸缟纤龥]有來(lái)上學(xué)。)

  例:Don't believe him.

 。ú灰嘈潘脑。)

  注:“have”表達(dá)“有”以外的意義時(shí),其否定句通常使用助動(dòng)詞“do”,例如:

  例:Usually I don't have (=eat) breakfast on Sunday morning.

 。ㄍǔP瞧谔煸缟衔也怀栽绮汀#

  例:She doesn't have (=drink) coffee for breakfast.

 。ㄋ话芽Х瘸渥髟绮秃。)

  例:We didn't have (=enjoy) a good time there yesterday.

 。ㄗ蛱煳覀?cè)谀抢锿娴貌挥淇。?/p>

  不過(guò)美式英語(yǔ)“have”作“有”的意義使用時(shí)也如一般動(dòng)詞使用助動(dòng)詞“do”,例如:

  例:I don't have brothers.

 。ㄎ覜]有兄弟。)

  例:We didn't have time enough to finish the work.

 。ㄎ覀儺(dāng)時(shí)沒有足夠的時(shí)間完成那件工作。)

 。2)使用“not”以外的否定詞

  “not”以外的否定詞有:

 。╝)副詞:never,seldom,hardly,little,neither,etc.

  例:She never comes to school late.

  (他上學(xué)從不遲到。)

  例:She seldom comes to see me.

  (她不常來(lái)看我。)

 。╞)形容詞:no,few,little,etc.

  例:I have no brothers.(=I don't have brothers.)

 。ㄎ覜]有兄弟。)

  例:He has few friends in Hong Kong.

 。ㄋ谙愀蹘缀鯖]有朋友。)

  (c)代詞:nothing,nobody,none,etc.

  例:I know nothing about computer.

 。▽(duì)于電腦我一竅不通。)

  I found nobody about computer.

  (在那棟房子里我沒看到任何人。)

  注:1.有些文法書認(rèn)為“Not +V”為句子否定法,是否定句,而“no +n.或如nothing,etc.”為單詞否定法,不宜稱為否定句。例如:

  例:He doesn't have brother.(否定句)

  He has no brothers.(單詞否定,但應(yīng)視為肯定句,因?yàn)橹^語(yǔ)動(dòng)詞是肯定。)

  請(qǐng)注意下面兩句的意義上的區(qū)別。

  例:He doesn't have a breakfast.

  He has not a breakfast.

  (他不吃早餐。——否定句)

  例:He has no breakfast.

 。ㄋ麤]有早餐可吃。——單詞否定,肯定句)

  2.否定也可以借用前綴或后綴來(lái)表達(dá),例如:

  例:He is honest.

 。ㄋ钦\(chéng)實(shí)的。)

  He is dishonest.(=He in not honest.)

 。ㄋ徽\(chéng)實(shí)。)

  例:They have children.

 。ㄋ麄冇行『ⅰ#

  They are childless.(=The don't have children.)

 。ㄋ麄儧]有小孩。)
