陈述句改否定句
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。

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。

陈述句改双重否定句的改法与技巧
陈述句改双重否定句的改法与技巧
将陈述句转换为双重否定句需要遵循一定的规则和技巧。
下面是一些步骤和注意事项,仅供参考:
1. 确定否定词:首先,确定你想要在句子中使用的否定词。
常用的双重否定词包括“并非不”、“不是不”、“不会不”、“无不”等。
2. 找出谓语动词:在原句中找到谓语动词,这是改写的关键部分。
3. 确定句意:在改写句子时,要确保句子的意思与原句相同,没有改变。
4. 替换词语:将找到的谓语动词替换为选定的否定词,保持句子逻辑严密。
5. 检查语法:最后,检查改写后的句子是否符合语法规则,确保句子通顺。
下面是一个示例,展示如何将陈述句转换为双重否定句:
示例:这本书非常重要。
1. 确定否定词:“并非不”
2. 找出谓语动词:“重要”
3. 确定句意:这本书并非不重要。
4. 替换词语:“重要”替换为“并非不重要”
5. 检查语法:改写后的句子“这本书并非不重要”符合语法规则,通顺易懂。
通过以上步骤和技巧,你可以轻松地将陈述句转换为双重否定句。
但需要注意的是,双重否定句有时可能会产生歧义,因此在使用时需要谨慎考虑。
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!。
