变否定句规则
变否定句规则
一、一般现在时变否定句的规则.
(a) 含有am is are 的句子,变否定句时, 只需在am is are 后加not.
例1 This is a book.
否定句This is not a book .
例2 I am a teacher .
否定句I am not a teacher .
例3 These are pens .
否定句These are not pens .
(b) 含有实义动词的句子，变否定句分两步。
（1）如果主语是第三人称单数时，要在实义动词前加doesn't,后面的动词用原形。
例1 He eats an apple.
否定句He doesn't eat an apple.
例2 Jim does his homework.
否定句Jim doesn't do his homework.
例3 Marry goes to school.
否定句Marry doesn't go to school.
(2) 如果主语不是第三人称单数时，只需在实义动词前加don't.
例1 I teach English.
否定句I don't teach English.
例2 They go to school.
否定句They don't go to school.
例3 We sing a song. 否定句We don't sing a song.
(c) 含有情态动词的句子,变否定句时,只需在情态动词后加not.
例1 I can dance.
否定句I can not dance. 或I can't dance.
例2 They can speak English.
否定句They can not speak English. 或They can't speak English.
例3 He must go home.
否定句He must not go home. 或He mustn't go home.
例4 He must be on the playground.
He can not be on the playground.
析：当must be用来表示推测，有“一定”的含义时，
否定式要用can not.
例5You must say something at the mecting.
You needn’t say anything at the mecting.
析：当“must+行为动词”用来表示“必须”的含义时，
其否定式可用needn’t 或mustn't表示“不需要”，“不必”，
语气委婉，must not表示“禁止”，“千万别”语气生硬。
例6 You may come in now.
You mustn't come in now.
析：may作为情态动词表示“可以”时，其否定式用must not,而不用may not.
例7 He may watch TV .
He mustn't watch TV.
注意:
(1) 见到some 变否定句时,要换成any.
例1 I eat some apples.
否定句I don't eat any apples.
例2 He has some books.
否定句He doesn't have any books.
例3 He does his home work.
否定句He doesn't do his home work.
(2) 见到and 变否定句时,要换成or.
例1 There is some air and water on the moon.
否定句There isn't any air or water on the moon.
例2 He has some brothers and sisters.
否定句He hasn't any brothers or sisters.
例3 He eats apples and oranges.
否定句He doesn’t eat apples or oranges.
(3) 见到too和also变否定句时,要换成either.
否定句Tom doesn’t go to school either.
too和also用于肯定句中时，否定句中用either替换。
（4）见到already变否定句时,要换成yet。
例1 He has had supper already.
He hasn’t had supper yet.
随着对谓语动词的否定，某些副词也要作相应的变动。
英语句型转换错误分析：肯定句变否定句
1. I think she is there.
误：I think she isn’t there.
正：I don’t think she is there.
析：英语中think, believe, expect, suppose等表示信念和揣测的动词，
后接that从句时，习惯上将从句中的否定形式转移到主句上，
即否定主句谓语，不否定从句谓语。
2. He can sing this song and that one.
误：He can not sing this song and that one.
正；He can not sing this song or that one.
析：肯定句中的连词and在否定句中一般要改为or。
3. Tom went to school too.
误：Tom didn’t go to school too.
正：Tom didn’t go to school either.
析：too和also用于肯定句中时，否定句中用either替换。
4. He has had supper already.
误：He hasn’t had supper alre ady.
正：He hasn’t had supper yet.
析：随着对谓语动词的否定，某些副词也要作相应的变动。
5. He had a good rest just now.
误：He hadn’t a good rest just now.
正：He didn’t have a good rest just now.
析：have在表示开会、吃饭、休息、进行体育锻炼等词组中是行为动词，否定句用助动词来完成。
误：Let’s don’t do it.
正：Don’t let’s do it.或Let’s not do it.
析：let后接的是不带to的不定式，变为否定式，
直接在句首前加Don’t或在不定式前加not。
7. He always gets there on time.
误：He doesn’t always get there on time.
正：He never gets there on time.
析：He doesn’t always get there on time意为
“他并非老是准时到那儿”，是部分否定，
习惯上把句中的副词改为相应的表示否定的副词即可。如：
It often rains here. It seldom rains here.
8. Be here early tomorrow.
误：Be not here early tomorrow.
正：Don’t be here early tomorrow.
析：祈使句的否定，一般在谓语动词前加do not的缩写don’t。
9. You had better come.
误：You didn’t have better come.
正：You had better not come.
析：had better相当于一情态动词，不可分割，
因此not应放在其后。would rather也是如此。
10. Both Tom and Xiao Ping went to school.
误：Both Tom and Xiao Ping didn’t go to school.
正：Neither Tom nor Xiao Ping went to school.
析：一个句子中如果有不定代词both，all, every改为否定式时，
要把这些不定代词改为相应的表示否定的代词。
二一般过去时变否定句规则
(a) 含有was were 的句子,变否定句时,只需在was were 后加not.
例1 This was a book.
否定句This was not a book . 或This wasn't a book .
例2 I was a teacher .
例3 These were pens .
否定句These were not pens .或These weren't pens
(b) 含有实义动词过去式的句子，变否定句时，
只需在实义动词过去式前加didn't，后面的动词用原形。
例1 He ate an apple.
否定句He didn't eat an apple.
例2 Jim did his homework.
否定句Jim didn't do his homework.
例3 Marry went to school.
否定句Marry didn't go to school.
(c) 含有情态动词过去式的句子,变否定句时,只需在情态动词过去式后加not.
(can could,may might ,need need ,must must)
例1 I could dance.
否定句I could not dance.
或I couldn’t dance.
例2 They could speak English.
否定句They could not speak English.
或They couldn’t speak English.
例3 He could swim,so can I.
He could swim,neither(nor)can I
析：在“陈述句+so+助（系情态）动词+主语”结构中，
若改为否定句，除陈述部分加副词not外，还需将so改为neither或nor。例4 He must go home.
否定句He must not go home.
或He mustn't go home.
例5 He must be on the playground.
He could not be on the playground.
析：当must be用来表示推测，有“一定”的含义时，否定式要用can not.例6 You must say something at the mecting.
You needn’t say anything at the mecting.
其否定式可用needn’t 或mustn't表示“不需要”，“不必”，
语气委婉，must not表示“禁止”，“千万别”语气生硬。
例7 You might come in now.
You mustn't come in now.
析：may作为情态动词表示“可以”时，其否定式用must not,而不用may not.例8 He might watch TV .

陈述句改成双重否定句的方法和步骤
陈述句改成双重否定句的方法和步骤： 1、根据句子意思，选择恰当的双重否定词； 2、替换或删去原句中“要、得(děi)、都、应该、只好、一定、必须、肯定”等词语； 3、删去原句中“很、非常、十分、分外、更加”等表示程度深的词语； 4、检查改后的句子是否读得通顺。 双重否定词及分类： 1、不得不、不能不、不会不、不是不、不敢不； 2、无不、无非、没有不、不是没有、不可能不； 3、不……不……、没有……不……、非……不可。 双重否定是一句话中有两个否定词语，加强了肯定的意思。双重否定句的作用是加强语气。分类 双重否定句主要有三种形式。一种是两个否定副词连用，一种是一个否定副词加上一个否定意义的动词，再一种是一个否定副词（或否定意义的动词）加上反问语气。这三种句式中，否定副词（或否定意义的动词）加反问语气的，都具有加强语气的作用。例如，“敢于这样做的人，难道不是一个英雄吗？”，意思就是“是一个英雄”，但语气更强烈，强调了敢于这样做的人是一个“大大的英雄”。 双重否定有两种形式： 1、由两个不构成。如：这件事我不得不做。 2、由一个反问词(难道，怎能等)加一个不组成，构成反问句．但也是双重否定句． 双重否定句就是表示肯定的意思，语气比陈述句强烈． 1、香港回归伟大的祖国，我们不得不感到无比自豪。 2、您为我们付出了这样高的代价，不得不表达您对中国人民的友谊。 3、没有哪个小孩子不喜欢小动物。 4、我对同学们的勇敢精神，从心底里不得不感到无限的敬佩。 5、信赖，不得不创造出美好的世界。 6、这不会不是伟大的奇观。 7、你不得不知道这件事。 8、我们不得不建成了希望小学。 9、詹天佑不会不是我国杰出的爱国工程师。 10、星期天,我们非去看排球赛不可。 11、报纸的诱惑力如此之大，每日非要读它不可。 12、他这样做虽然过分了点，但并不是没有道理的。 13、写得不怎么样，不是没有希望的。 14.我不得不承认那个是我的东西. 15.幼儿园的小朋友没有一个不喜欢王老师。 16.你不会不知道这件事。 他不可能不那么高。 这些灯没有哪两盏是相同的。 他不可能不迟到。
一般疑问句,否定句改写
一般疑问句 一般疑问句是疑问句的一种。它是指用yes（是）或no(否）来回答的句子。其结构是： 系动词be/助动词/情态动词+主语+其他成分 通常回答为： 肯定：Yes，+主语+提问的助动词. 否定：No,+主语+提问的助动词+not. 如: Are you from Japan﹖ Yes I am．/ No I’m not． Is her sister doing her homework now﹖ Yes she is． / No she isn't． Does he work in a bank﹖ Yes he does． / No he doesn't． Do you live near your school﹖ Yes I do． / No I don't． Can you speak French﹖ Yes I can． / No I can't． May I go home now﹖ Yes you may． / No you mustn't． 注意： 1．将陈述句变为一般疑问句时,如句中有be 动词（am/ is/ are）时，可直接将它们提至主语前。如主语为第一人称，应将其改为第二人称。如：I’m in Class 2Grade 1．→ Are you in Class 2Grade 1﹖ We’re watching TV．→ Are you watching TV﹖ 2．陈述句中有情态动词（can may must …)时,也可直接将它们提至主语前，即可成为一般疑问句。如： He can swim now．→ Can he swim now﹖ The children may come with us．→ May the children come with us﹖ 3．陈述句中只有一个实义动词作谓语且其时态为一般现在时，变为一般疑问句时要在句首加do或does 主语后的实义动词用原形。如： I like these animals．→ Do you like these animals﹖ She wants to go to the movies．→ Does she want to go to the movies﹖
变否定句
1. 由系动词am，is，are构成的句子：变一般疑问句时把am，is，are提到句子的前面，句尾用问号即可。变否定句时直接在am，is，are后面加not即可。例如： 肯定句:He is a student. 一般疑问句: Is he a student? 否定句: He is not a student. 反问句: He is a student, isn't he? He isn't a student, is he? 画线提问: 对he提问: Who is a student? 对a student 提问: What is he? or What does he do? 2. 由情态动词can, may, should等构成的句子: 变一般疑问句时把can,may,提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加not即可. 例如: 肯定句: She can swim. 一般疑问句: Can she swim? 否定句: She can not swim. 反问句: She can swim, can't she? She can not swim, can she? 画线提问: 对she提问: Who can swim? 对swim提问: What can she do? 3. 由行为动词构成的句子: 需要加助词do或does. 变一般疑问句时把do/does 放在句子前面. 例如: 肯定句: They play football after school. 一般疑问句: Do they play football after school? 否定句: They don't (do not) play football after school. 反问句: They play football after school, don't they? They don't play football after school, do they? 画线提问: 对they提问: Who play football after school? 对play football提问: What do they do after school? 对after school提问: When do they play football?

肯定句改双重否定句的方法和练习含答案
1.肯定句、否定句的转换 2.双重否定句、陈述句的转换 双重否定句：就是否定两次,即表示肯定的意思，但必须有否定的意义在里面。（双重否定句的作用是加强语气。） 双重否定句与陈述句的转换：（类似于反问句）一、双重否定句 双重否定就是否定两次,即表示肯定的意思，但必须有否定的意义在里面。。 例如:“他不是不来”意思是他要来的。包括有双重否定的句子就是双重否定句。 比如: （1）我不得不承认那个本是我的. 分析：“不得不”就是双重否定这句话的原意为：我承认那个本是我的。 （2）幼儿园的小朋友没有一个不喜欢王老师。 “没有一个…不”就是双重否定词 这句话的原句为：幼儿园的小朋友都喜欢王老师。 （3）你不会不知道这件事。分析：“不
双重否定从字面上就知道，是一句话中有两个否定词语，表示肯定的意思。 双重否定句是相对于单纯否定句而言的，它用否定加否定的形式，表达肯定的语意。一般的语法书普遍认为，双重否定句的作用是加强语气。 在双重否定句中，有那么几个可以用： 不得不、不能不、难道……不…… 不可能不、 不会不、怎么会…… 不、不是不等 双重否定句主要有三种形式。 （1）、一种是两个否定副词连用，谓语前面加“不。。。不”，也就是负负为正的原理。可用“没有……不……”“不……不……” 如“我不能不被他感动得流下泪来。”又如：这种新产品质量好，价格也便宜。改为：这种新产品质量不能说不好，价格也不能说不便宜。 （2）、一种是一个否定副词加上一个否定意义的动词，
如“我们不能否认老一辈人的功劳。” （3）、再一种是一个否定副词（或否定意义的动词）加上反问语气。 如“他感人的事迹，叫我怎么不流泪呢？” 另外、把肯定句改为多重否定 表否定，使否定成分的个数成奇数个即可 例如：我们不得不承认太阳不是绕地球运行的。这三种句式中，否定副词（或否定意义的动词） 例如，“敢于这样做的人，难道不是一个英雄吗？”（《内蒙访古》），意思就是“是一个英雄”，但语气更强烈，强调了敢于这样做的人是一个“大大的英雄”。
