1.英语的否定句怎么写
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。
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 /alwaysnever, somebodynobody,somethingnothing, 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.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” 。
3.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?
4.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。
5.英语一般疑问句,肯定回答否定回答 同义句否定句怎么写
一、肯定句改否定句的方法 — 一步法1、在be动词(am ,is, are ,was, were)后加否定词not。
如:is not , are not , am not, was not, were not;其中is not=isn't, are not= aren't, 前者为“完全形式”,后者为“缩略形式”。2、在can,should,will等后加not。
如:cannot, should not, will not;3、上述都没有的,在动词前加助动词do, does, did的否定形式don't/doesn't/didn't。4、some 改成any。
如: I am a girl. → I am not a girl. You are a student. →You are not a student. →You aren't a student. This is Tom's bag, → This is not Tom's bag. → This isn't Tom's bag. 答题方法是;否定词not在be后边。 二、肯定句改一般疑问句的方法 — 三步法1、把be动词放在句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。
2、把can,shall, will等放到句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。3、上述都没有的,在句首请助动词Do/Does/Did帮忙,剩下的照抄,(some 改成any,I改成you,my改成your,)句点改成问号。
注意:句首的第一个字母要大写,句尾标点应为“?”。如: I am in Class 6. →Are you in Class 6? You are from America. →Are you from America? It is an orange. →Is it an orange? 答题方法是:要想提问,be提前,句末“?”别忘了。
4、就一般疑问句回答 一般疑问句有两种回答,即:肯定回答和否定回答。其中,肯定回答用yes,否定回答用no。
语句顺序为:Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn't/ aren't/wasn't/weren't.|can't.|don't/doesn't/didn't|.。如: (A)—Are you an English teacher? —Yes, I am. /No, I am not. (B)—Is that a bird? —Yes, it is./ No, it isn't. 三、肯定句改特殊疑问句(对划线部分提问)的方法 — 四步法 ①特殊疑问句的构成。
即:特殊疑问句 = 特殊疑问词 + 一般疑问句 ②掌握特殊疑问词what(对事、物提问);who(对人提问);where(对地点提问); how(对状况提问); how old(对年龄提问); what colour(对颜色提问)等。 ③答题方法:一找二变三整理。
所谓“一找”,即根据划线部分内容找出合适的特殊疑问句;“二变”,即把余下部分变成一般疑问句;“三整理”,即按特殊疑问句的语序整理句子,注意句首字母要大写,句尾标点为“?”。如: (1)This is Tom. → Who is this? (2)That is an orange. →What is that? (3)Jane is from America. →Where is Jane from? (4)Miss Wu is fine. → How is Miss Wu? (5)He is ten. → How old is he? 四步法1、在一般疑问句的基础上,句首添加一个疑问词即可,可根据划线部分确定是什么疑问词。
2、接着找be动词或can,shall, will等放在疑问词后面,若没有则请助动词do/does/did帮忙,写在疑问词后面,how many除外,必须先写物品,再写be动词等。3、划线部分去掉后剩下的内容照抄,(some 改成any,my改成your等)4、句点改成问号。
四、同义句型转换 同义句型转换,是把意思相同或相近的句子用不同的词汇、短语及句型表示出来。如: I'm Peter. → My name is Peter. Tom is tall. →Tom isn't short. 总之,要教好句子,首先要给学生渗透句子的纲,学生才可以依葫芦画瓢,有纲可循。
当然,平时还必须增加阅读量,实践量,不断总结经验,培养语感掌握技巧,提高句子的准确性。补充说明:“句型转换”题是用来考查学生对句子结构变化所掌握的程度。
常见的出题方式:陈述句变成一般疑问句,并做出肯定或否定回答;肯定句变成否定句;同义句型转变;对划线部分提问等等。Amen!参考资料: 。
