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在我们的语文学习中，陈述句改成双重否定句是一个重要的知识点。

掌握这一技巧不仅能够丰富我们的语言表达，还能让我们更准确、更生动地传达自己的意思。

那么，如何将陈述句顺利地改成双重否定句呢？下面就为大家详细介绍陈述句改成双重否定句的方法和步骤。

首先，我们要明白什么是陈述句和双重否定句。

陈述句是用来陈述一个事实或者表达一个观点的句子，语气比较直接和平稳。

例如：“他今天去上学了。

” 而双重否定句则是用两个否定词来表达肯定的意思，语气比陈述句更加强烈。

比如：“他今天不可能没去上学。

”接下来，我们来看看将陈述句改成双重否定句的方法。

第一种方法是在陈述句中加上两个否定词，常见的否定词有“不得不”“不能不”“非……不可”“没有……不”“不会不”等等。

比如，把“我喜欢你”这个陈述句改成双重否定句，可以这样改：“我不能不喜欢你。

”再比如，“他会来参加聚会”，改成双重否定句就是“他不会不来参加聚会”。

第二种方法是在陈述句中加入“无不”“无非”“没有一个不”等词。

例如，“大家都很开心”可以改成“大家无不开心”；“这道题很简单”可以改成“这道题无非很简单”；“我们班的同学都很优秀”可以改成“我们班没有一个同学不优秀”。

在进行陈述句改双重否定句的过程中，需要遵循一定的步骤。

第一步，认真分析原陈述句的意思，确定要表达的肯定的核心内容。

这是非常关键的一步，只有明确了原句的意思，才能保证改后的双重否定句意思不变。

第二步，根据原句的意思，选择合适的否定词。

比如，如果原句表达的是一种主观的意愿或态度，通常可以用“不得不”“不能不”；如果原句强调的是普遍的情况或客观的事实，可能更适合用“无不”“没有一个不”等。

第三步，把选择好的否定词加入到原陈述句中，注意要保证句子通顺、合理。

同时，还要检查修改后的句子是否准确地表达了原句的意思，是否存在语法错误。

下面通过一些具体的例子来进一步说明。

例1：“他是一个好学生。

陈述句变否定句

陈述句变否定句一.句子中有am is are时，在其后加not。例如：① I’m a student. I’m not a student. ② Sarah is going to the hospital. Sarah is not going to the hospital. ③ Sarah is watching TV. Sarah is not watching TV. ④ They are good friend. They are not good friend.
二. 句子中有can will时，在其后加not。例：He can swim. He can not swim. I will go to the park. I will not go to the park. 练习：（1）Tiger can run fast. （2）They will make a snowman. （3）Amy will take a dancing class. （4）She can go ice-skating. （5）Aunt will cook dinner.
三. 句子中无am is are can will。 1. 动词为原形时，在动词前加don’t。例：I go to school by bike. I don’t go to school by bike. 练习：（1）They eat lunch at school. （2）I have to do my homework. （3）Boys play football at noon. （4）I want to send it today. （5）Three pandas eat bamboos.
2. 动词为单三形式时，在动词前加 doesn’t , 动词单三形式变原形。例：He eats breakfastห้องสมุดไป่ตู้at home. He doesn’t eat breakfast at home. Mike goes to bookstore by bus. Mike doesn’t go to school by bus. 练习：（1）She wants to eat noodles. （2）Mr Zhang has to wash clothes. （3）Jack makes mooncakes for me. （4）John wears a life jacket. （5）The elephant drinks water .

陈述句改为一般疑问句或否定句

一、陈述句改为一般疑问句：1.当句子中含有be动词(am is are was were)或情态动词(can,could,may,might,will,would,must,need,shall,should等）或在完成时态中(has/have/had+过去分词)时，把这些助动词提到句首。

如：①He is a docter.-----Is he a docter? ②They were in the house yesterday.----Were they in……?③Tom can swim.----Can Tom swim? ④He has been to the park.----Has he been to the park? 另外，为符合实际习惯I am/We are..…------Are you…? I was/We were…-----Were you….?I /We can…-----Can you…..? I /We have +过去分词…..------Have you…….?2.当句中含有实义动词时，也就是句子不含上面所提到那些助动词时，必须在句首加DO/Does/Did,具体情况分以下三方面：㈠当句子中含有动词原型时，在句子前加Do, 其中，I+动词。

------Do you…?如：①I like music.---Do you like music? ②They work here.----Do they work here?㈡当句子中含有的动词加S或ES时，即句子是一般现在时，且主语为第三人称单数时，在句子前加Does.如：①He likes music.------Does he like music?②Tom comes from China.-----Does Tom come from China?（注意在此情况下，应把疑问句中的动词变原型。

）㈢当句子中的动词为过去式，在句子前加Did再把动词变原型。

英语变否定句的方法

英语变否定句的方法英语中，要将一般陈述句变成否定句，通常需要在句子中加入否定词或使用辅助动词do/does/did，并将动词原形改为其否定形式。

下面我将详细解释英语中变否定句的方法，并给出一些例子。

1. 使用否定词：在英语中，有很多表示否定的词，比如：not、never、no、none、neither、nobody、nowhere等。

将这些词插入到句子中可以将句子变成否定句。

例如：- He is happy.（他很开心。

）- He is not happy.（他不开心。

）- They have finished their work.（他们完成了工作。

）- They have not finished their work.（他们还没完成工作。

）2. 使用辅助动词do/does/did：在一般陈述句中，辅助动词do/does/did用于疑问句和否定句中，以表示动作的否定。

例如：- She goes to school.（她去学校。

）- She does not go to school.（她不去学校。

）- He likes ice cream.（他喜欢冰淇淋。

）- He does not like ice cream.（他不喜欢冰淇淋。

）- They played soccer.（他们踢足球。

）- They did not play soccer.（他们没踢足球。

）需要注意的是，do表示现在和将来的否定，does表示第三人称单数的否定，did表示过去的否定。

3. 动词变为否定形式：在英语中，有些动词的否定形式是在动词原形后面加not构成的。

通常是将动词原形的词尾改为not。

例如：- I understand.（我理解。

）- I do not understand.或者I don't understand.（我不理解。

）- She knows the answer.（她知道答案。

）- She does not know the answer.或者She doesn't know the answer.（她不知道答案。

小升初专项：陈述句变否定句

陈述句变否定句陈述句：是用来陈述一件事情或表示一种看法，可分为肯定句和否定句两种形式。

一、变否定句：1.当谓语动词是be动词,am, is are或者过去时was, were时，直接在这些词后面加not构成否定形式，即am not, is not=isn’t , are not=aren’t。

如果句子里有some，在否定句中要变成any。

and 变成or。

Eg. She is a beautiful girl. (改为否定句)- She isn’t a beautiful girl.There are some students in Sun school. (改为否定句)-There aren’t any students in Sun school.2.当句子中谓语动词是助动词will,情态动词can, could, should,must等时，直接在助动词和情态动词后加not 变为否定句。

注意will not = won’t, can not=can’t, must not =mustn’t 表示禁止。

如果句子里有some，在否定句中要变成any。

and 变成or。

Eg .My family will go to Beijing and Qingdao next Sunday . (改为否定句)-My family will not go to Beijing or Qingdao next Sunday.They can run very fast. (改为否定句)-They can’t run very fast.3.Eg.谓语动词是行为动词而又没有助动词或情态动词时，必须在谓语动词前加助动词，一般现在时加助动词do ，第三人称单数加does，一般过去时加did，再和not构成否定结构。

don't, doesn't, didn't后都用动词原形。

如果句子里有some，在否定句中要变成any。

陈述句变否定句

陈述句变否定句英语语法中，有一种重要的结构叫做否定句。

否定句的作用是通过否定动词的信息来表达一个相反的意见。

否定句在英语中使用得非常普遍。

在学习英语的过程中，掌握如何正确地使用否定句是非常关键的。

为了形成一个否定句，需要把一个陈述句反转过来，加入否定词。

在英语中，常用的否定词有 not, never, no, nothing, nobody, none, neither, nor, scarcely, hardly等等。

以下是一些例句：•陈述句：I am eating breakfast. 否定句：I am not eating breakfast.•陈述句：He likes to play soccer. 否定句：He doesn’t like to play soccer.•陈述句：She has a dog. 否定句：She doesn’t have a dog.•陈述句：We are going to the party. 否定句：We are not going to the party.可以看到，要变成否定句，需要在动词前加上否定词 not。

在形式上，否定句只是简单地把动词和否定词结合在一起。

不规则动词的否定形式不过，有些动词的否定形式是不规则的。

这些不规则动词的否定形式需要注意，因为它们的形式与常规构造相比是个例外。

以下是一些例子：•陈述句：He is here. 否定句：He is not here.•陈述句：She can run fast. 否定句：She cannot run fast.•陈述句：I have some money. 否定句：I don’t have any money.•陈述句：They will come later. 否定句：They won’t come later.可以看到，一些不规则动词的否定形式不是简单地在动词前加 not。

例如，动词 can 在否定形式中是 cannot，动词 have 在否定形式中是don’t have。

陈述句改否定句的方法和技巧

陈述句改否定句的方法和技巧
1. 嘿，咱先得注意句子里的动词呀！比如“他喜欢画画”，把“喜欢”改成“不喜欢”，那就变成否定句啦，“他不喜欢画画”。

你想想，这是不是很简单呀！
2. 还有哦，看看有没有表示肯定的副词呢！像“我经常去公园”，把“经常”改成“不经常”，“我不经常去公园”，这不就成了嘛，这多容易操作呀！
3. 哎呀呀，要是句子里有“是”这样的判断词，那更好改啦！“这是我的书”，变成“这不是我的书”，就这么轻松搞定，是不是超有意思呀！
4. 可别忘了那些表示程度的词哟！比如说“她非常漂亮”，把“非常”改成“不很”，“她不很漂亮”，这方法咋样，很妙吧！
5. 如果有数量词也得注意呀！像“三个苹果”，改成“不是三个苹果”，简单粗暴但有用呀，嘿嘿！
6. 咱再说说形容词呀，“天气晴朗”，把“晴朗”改成“不晴朗”，“天气不晴朗”，就这么简单呀，学会了吧！
7. 有没有那种直接表示肯定的词呀，比如“一定”，“他一定会来”改成“他不一定会来”，多浅显易懂呀！
8. 碰到有多个肯定因素的句子也别怕呀！“他又聪明又勇敢”，那可以改成“他又不聪明又不勇敢”，哈哈，你学会了没呀！
总之呀，把陈述句改成否定句其实并不难，只要咱多留意句子里的这些要点，多练习练习，肯定能轻松掌握的啦！。
