1. 简单句中含有系动词be、情态动词和助动词时,变否定句时需在系动词be、情态动词和助动词后加not。

否定句的英语怎么写

如: I am a teacher.→I am not a teacher. He can help me.→He can't help me. 2.简单句中谓语动词为行为动词时,要根据时态选用do的相应形式,把肯定句变为否定句。如: The little girl wants to go there.→The little girl doesn't want to go there. He did his work yesterday.→ He didn't do his work yesterday. 3.祈使句变否定句时,一般在句首加Don't,但Let us或Let's开头的祈使句在 Let us或 Let's后加not即可。

如: Put them over there.→Don't put them over there. Let us go home.→Let us not go home. 4.主从复合句中,主句是I think,I believe等结构,变否定句时,形式上否定主句,实际上否定从句。如: I don't think chickens can swim .我认为鸡不会游泳。

5.“had better +动词原形”,变否定句时为“had better not +动词原形”。如: You'd better go to school.→ You'd better not go to school. 6.动词不定式变否定式时,常在不定式to前加not。

如: The teacher tells me to do it.→ The teacher tells me not to do it. 7.使役动词和感官动词(make,let,hear,see,watch等)后接省略to的不定式,此种不定式变否定句时只需在省略to的动词原形前加not。如: I saw her work.→I saw her not work. 8.特殊形式的否定句,有以下几种: (1)肯定句含有every-的合成词时,变否定句时改为no-。

如: Everything is ready.→Nothing is ready. (2)肯定句中含有always, usually和ever时,变否定句时改为never。如: He is always late for school.→He is never late for school. (3)肯定句含有many,much时,变否定句时分别改为few,little。

如: Many students know him.→Few students know him. (4)肯定句中含有still时,变否定句时应改为no longer。如: Tom is still in bed.→Tom is no longer in bed. (5)肯定句含有both, both。

and,all时,变否定句时应改为never,neither。nor,none。

如: Both of us are students.→Neither of us is a student. (6)肯定句含有nearly, almost时,变否定句时应改为 hardly。如: Lily nearly knows him .→Lily hardly knows him . (7)肯定句含有“形容词+ enough”时,变为否定句时应改为“too +形容词的反义词”。

如: He is short enough to reachit.He is too tall to reach it. (8)谓语动词是be,have(有)或谓语含有助动词、情态动词时,直接在这些词后加上否定词not。如: She can swim.She can't swim. (9)谓语动词是行为动词时,要在该动词前加上do /does /did not,该词恢复原形。

如: He gets up early.He doesn't get up early. (10)既要否定谓语动词,又要变换句中的单词。如: He can read and write.He can't read or write. (11)用含否定意义的词或词组取代肯定句中的某些词或词组。

如: I know both English and Chi- nese.I know neither English nor Chinese. 类似的有:ever /alwaysnever, somebodynobody,somethingnothing, everybody no one,almost hardly 9.祈使句的肯定式变否定式 (1)一般在动词前加上 don't。如: Open the window .Don't open the window. (2)含有“Let's。”

的祈使句,一般用“Let'snot。”的形式,美国人偶尔也用“Don'tlet's。”

这一形式。加强语气时使用“Let'sdon't。”

这一形式。如: Let's go there.Let's not go there. 10.复合句的肯定式变否定式 一般将主句变为否定式。

如:I saw her when I left .I didn't see her when I left.。

2. 否定句中的也用英语怎样写

否定句中的也用英语:either ['iðɚ]。

pron. 任一,两方,随便哪一个;两者中的一个或另一个

adj. 两者之中任一的;两者之中每一的

prep. 任何一个

用法:either只能用在否定句中,常常和否定词not连用,用来否定词组或句子,其含义表示也不 ,在一般情况下只能放在句末来加强整个句子的语气。

扩展资料

在否定句中,还有其他的否定词。

1、nor和neither

结构︰(前句)否定句,+(后句)nor/neither+肯定式动词+主语,即倒装句。

例如:He hasn't been to Europe, nor have I.

翻译:他没去过欧洲,我也没有。

2、半否定词:hardly, rarely, scarcely,seldom,little,few等

例如:It hardly (scarcely) matters.

翻译:没有什么关系。

3、否定词no,none,nobody,nothing,nowhere, neither, never表达完全否定的意义。

例如:No student in this school is from Asia.

翻译:这个学校没有一个学生是来自亚洲的。

3. 英语的否定句和肯定句怎么写

一.肯定句:是指用肯定的语气来陈述的句子。

例:

This is my pen。

这是我的笔。

He works in a hospital。

他在医院工作。

There are four fans in our classroom。

我们教室里有四个风扇。

二.否定句:含有否定词或表示否定意义词的句子。

例:

This is not my pen。

这不是我的笔。

He does not (doesn't) work in a hospital。

他不在医院工作。

There are not (aren't) four fans in our classroom。

我们教室没有四个风扇。

三.肯定变否定,有以下2种情况

1.有am / is / are,就在它们后面加 not。

am → am not

is → is not

are → are not

比如:

I am a girl。→ I am not a girl。

我是女孩。→我不是女孩。

2.没有 am / is /are, 但有表示动作的动词(比如eat),就在动词前加 don't 或 doesn't, 动词为原形。

V原→ don't + V原

V(-s, -es结尾) → doesn't + V原

eat → don't eat

eats → doesn't eat

比如:

I drink cola。→I don't drink cola。

我喝可乐。→我不喝可乐。

She drinks cola。→ She doesn't drink cola。

她喝可乐。→她不喝可乐。

一.否定句主要是在肯定句的基础上加上了否定词 “not”。

二.有动词be的句子则“not”加在be后面,可缩写成“isn't,aren't”,但am not 一般都分开写。

三.没有动词be的句子则要先在主要动词的前面加上一个助动词(do,does,did),然后在它后面加上“not”,你也可以把它们缩写在一起如“don't , doesn't , didn't )。

四.上面三个助动词要根据人称和时态来选择,其中“does”只用于一般现在时主语是第三人称单数的情况,而“did”只用于一般过去时,不论主语是什么人称和数,都用“did” 。

4. 小学英语否定句、一般疑问句的写法窍门

陈述句改否定句:通常只要在谓语前后加not.

具体的加法为:在is,am,are,can,may后加not;在行为动词前don't(注意:如果主语是第三人称单数时,就得加doesn't,同时,将那动词加S的词还原(去掉那加上去的S).

This is an English car,改成否定: This isn't(is not) an English car.

陈述句改成一般疑问句时,只要把含有is,am,are,can,may的词,放到句首;如果陈述句中无上述那些词,就在句首加do,所不同的是得注意人称的变化:

如果是第一人称时,在改动时得变成第二人称,如果是第二人称时,得改成第一人称.

They are drivers-----Are they drivers?

You are his teacher.----Am I his teacher?

I am a student.----Are you a student?

The man cleans the desks-----Does the man clean the desks?

5. 怎样改为否定句 英语的

否定句的常见形式和用法 中学英语表达否定含义的句式形式多样,用法灵活。

准确地掌握与否定相关的语句形式和用法,有助于提高英语阅读理解的准确性。本文就中学英语中否定句的常见形式和用法总结如下: 一、常见否定句:否定副词not, seldom, never, hardly, rarely, nowhere等与谓语动词连用。

例如: I'm afraid that I can not attend your party this weekend. 恐怕这个周末我不能参加你们的聚会。I can hardly understand what he said just now. 我不能理解他刚才所说的话。

注意:这些否定副词用于句首时,主句要使用倒装语序。例如: Seldom does he go to work late. 他很少上班迟到。

Nowhere else can you find such a beautiful sunset. 你在别的地方不能见到如此美丽的日落。 Never in my life have I heard such nonsense! 我这辈子从来没有听过这种废话! 二、否定祈使句:由“Don't 或Never+ 动词原形”所构成。

例如: Don't give up trying even though it is difficult to learn English! 英语虽然难学,但千万别放弃尝试! Do not cut down the tree that gives you shade. 切勿忘恩负义。 Never judge people by their appearance. 不可以貌取人。

三、全部否定:由“否定主语(否定代词或no+名词)+ 肯定谓语”所构成。例如: Nothing is difficult if you put your heart into it. 世上无难事,只怕有心人。

None of us can speak French. 我们都不会讲法语。 No man is born wise. 人非生而知之。

注意:常用“neither/nor + 助动词/情态动词 + 主语”来表达“某人也不……”。例如: Jim didn't know her secret, neither/nor did Jack. 吉姆不知道她的秘密,杰克也不知道。

If you don't accept his invitation, neither shall I. 如果你不接受他的邀请,我也不接受。 四、否定转移:常见的否定转移有两种情况。

1. 含有原因状语从句的主从复合句,形式上虽然否定主句的谓语,然而意义上则是否定该原因状语,译为“并不因为……而……”。 例如:Galileo was not ready to accept it just because Aristotle had said so.伽利略并不只是因为亚里斯多德说过某事如何如何,就轻易相信它。

The mountain is not valuable because it is high. 山不在高。2. 当think, believe, suppose, expect, imagine等动词引导否定意义的宾语从句时,通常把从句中的not提前,把主句变成否定句,从句用肯定形式。

例如:We don't believe that the news is true. 我们相信这个消息不是真的。I don't think that he is honest. 我认为他不诚实。

注意:(1)把这些发生否定转移的句子变为反意疑问句时,疑问部分应与宾语从句主谓部分构成反意疑问句。例如:I don't think that he is honest, is he? 我认为他不诚实。

(2)not 常用在I think, I believe, I expect, I suppose, I guess, I'm afraid之后,构成省略句。例如:---Do you think it will be a fine day tomorrow? ---I'm afraid not. ---你认为明天天气会好吗?---恐怕不是。

---Do you believe that Rocket will win the game? ---I believe not. (=I don't believe so.)---你相信火箭队会赢吗?---我看不会。五、否定疑问句:常用来表示反问、惊讶、建议、赞叹等语气。

例如:Don't you know these traffic rules? 难道你不知道这些交通规则吗?Aren't you supposed to be working? 你不是应该正在干活吗?You look pale. Why don't you have a rest? 你看起来脸色苍白,为什么不休息一会儿?Isn't it a lovely day? 天气多好啊!注意:在回答否定疑问句时,要根据具体事实作答。例如:---Didn't you see the film Titanic yesterday? --- . I would like to have seen it. A. Yes, I did B. No, I didn't C. Yes, I didn't D. No, I did由于yes与肯定句连用,no与否定句连用,首先可排除C, D 两项。

A, B 形式都正确,但从题目语境中最后一句话“我倒希望自己看了那部电影。”可知事实上我昨天没有看电影,故答案选B。

如果把题干最后一句话改为“It's very moving.”,则说明我昨天看过电影,正确答案就应该选A。这种“根据事实作答”在运用中很不容易掌握,大家应该仔细体会其用法;同时,这种应答方法也适合于对“前否后肯型”反意疑问句和否定祈使句的回答。

例如:---You haven't been to Beijing, have you?--- . And I visited the Summer Palace. A. Yes, I have B. Yes, I haven't C. No, I have D. No, I haven't 从答语提示可知事实上我去过北京,故答案选A。全句译为:“——你没有去过北京,是吗?——不,我去过。

我还去参观过颐和园。”六、非谓语动词的否定式:通常把not或never放在非谓语动词to do, doing, p.p的前面。

例如:I advised him not to smoke but he wouldn't listen. 我劝他别抽烟,可他不愿意听。Not having received a reply, she wrote him another letter. 由于没有收到他的回信,她又给他写了一封信。

Not allowed to take part in the game, they felt very disappointed. 因为不让他们参加比赛,他们感到非常失望。七、双重否定句:由两个否定词搭配构成,表示一个较强的肯定语气。

例如:Without air or water, man can not live on the earth. 没有空气和水,人类是无法在地球上生存的。Don't try to operate this machine 。
