英语肯定句变否定句的基本方法(精彩3篇)

英语肯定句变否定句的基本方法 篇一

在英语中，将肯定句变成否定句是非常常见的语法现象。学会如何进行否定句的转换，对于提高英语表达的准确性和流利度非常重要。本文将介绍一些基本的方法，帮助读者掌握将肯定句变成否定句的技巧。

首先，将肯定句变成否定句的最简单方法是在句子前面加上一个否定词，比如"not"。这个方法适用于大部分情况，但需要注意的是，否定词在句子中的位置要符合语法规则。例如，将肯定句"I am happy"变成否定句，可以在句子前面加上"not"，变成"I am not happy"。同样地，将肯定句"They have finished their homework"变成否定句，可以在句子前面加上"not"，变成"They have not finished their homework"。

其次，另一种将肯定句变成否定句的方法是使用否定副词。否定副词包括"never"、"rarely"、"hardly"等等。这些副词通常放在句子中的程度副词之前，动词之后。例如，将肯定句"She always arrives on time"变成否定句，可以用"never"代替"always"，变成"She never arrives on time"。类似地，将肯定句"He often forgets his keys"变成否定句，可以用"rarely"代替"often"，变成"He rarely forgets his keys"。

除了使用否定词和否定副词，还可以通过改变句子中的动词形式来将肯定句变成否定句。比如，将肯定句"He enjoys playing soccer"变成否定句，可以将动词"enjoys"改为其否定形式"does not enjoy"，变成"He does not enjoy playing soccer"。类似地，将肯定句"They are studying for the exam"变成否定句，可以将动词"are studying"改为其否定形式"are not studying"，变成"They are not studying for the exam"。

最后，有一些特殊的动词需要特别注意。例如，动词"can"通常用于表示能力或可能性，其否定形式是"cannot"。将肯定句"I can swim"变成否定句，可以将"can"改为"cannot"，变成"I cannot swim"。类似地，将肯定句"She will go to the party"变成否定句，可以将"will"改为"will not"，变成"She will not go to the party"。

总之，将肯定句变成否定句是学习英语语法中的一个重要环节。通过加入否定词、否定副词，改变动词形式等方法，可以轻松地完成这一转换。希望本文介绍的基本方法能够帮助读者提高英语表达的准确性和流利度。

英语肯定句变否定句的基本方法

　　【导语】英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。本章主要介绍英语语法中的句子成分，希望对同学们的英语语法学习有所帮助。

　　1. be动词的否定式

　　be 动词根据不同的人称和时态有不同的形式，在一般现在时中是am , is , are可用作联系动词，构成否定式时，一律在其后面加否定词not.

　　He is reading. --- He is not reading. They are from China. --- They are not from China.

　　2. 情态动词的否定式

　　情态动词的否定式是在其后面直接加not. 如：

　　I can swim. --- I can’t swim. He can dance. --- He can’t dance. You should go to school at seven. --- You shouldn’t go to school at seven.

　　3. 实义动词的否定句

　　实义动词变否定句时，要借助助动词do , does，在一般现在时中用do或者does其句子结构为：主语+ don’t / doesn’t + 动词原形+其它 例如：

　　I like pop music. --- I don’t like pop music. He likes running. --- He doesn’t like running.

　　She does her homework at home. --- She doesn’t do her homework at home

　　句型35[主语+否定式谓语+微量词+名词+其他]

　　1. We must never for a moment porce ourselves from the masses.

　　2. The mother did not have a wink of sleep the whole night on account of the child's high fever.

　　3. He did not breathe a single word about it.

　　4. Though I have walked twenty miles, I am not a bit tired.

　　5. The little boy is do full of energy that he refused to stay put for any length of time.

　　[注] 表示微量词的词组中以 in the least为最常见，不少的微量词可用它代替。如：

　　句型36[...否定词+名词+大范围词语...]

　　4. He was not at all confused. 5. It is of no value at all.

　　6. This is a historical trend no force on earth can hold back.

　　[附注1] 与汉语中的否定式相对应的英语不一定要用否定式。如："很不好"，不能译成英语的"very not good", 应换一种说法， "This is very bad.", "It is not good at all." 汉语"这事我一点也不知道"可译作 "I am quite in the dark about the matter."或 "About this I knew nothing." 汉语"我很不喜欢喝酒。"可译作为 "I dislike wine very much."或 "I am not a bit interested in wine./I don't like wine at all./I am the last person to like wine.

　　其次要注意分析。汉语"一窍不通"，是缩小否定数量的说法，最好译成 "be utterly ignorant"或 "not know the ABC of…/know nothing of… 又如"世界上一切事物无不具有两重性"，这里有几个强调的词语："世界上"，"一切事物"，"无不"。"一切事物"不能用all/all things, 因此只能用缩小量的说法。 "There is not a single thing in the world without a dual nature."

　　[附注2] 一般说来，只要需要，所有的肯定句都可以改为否定句，但一定要依照前面所介绍的各种句型的要求。此外，还应考虑以下几点：

　　1) 逻辑上说不过去的不能改为否定句。Where is Mary? 不能改为 where isn't Mary?

　　2) 句型要求不能用否定式的。How hard-working he is! 不能改为 how hard-working he isn't!

　　3) 除句型28中列举的一些强调词语有分工外，以下词语只用于肯定句，否定句应采用括号中相对应的异根同义词。Some (not…any); too (not…either); so (neither, no more); a long way (not…far); a lot of/plenty of/a great deal of/a good deal of… (not…much of); as…as (not so…as); already still (not yet/ not any more/no more/ no longer…)

　　1. I have got some. → I haven't got any. 2. I see a great deal of him. → I didn't see much of him.

　　3. We went a long way. → We didn't go far. 4. I will do so still. → I'll not do

　　4) 注意may, must, need, can (could) 在肯定句与否定句中的含义变化，对应关系也会出现交错现象。

　　A. 表示许可用may (口语中常用can); 表示禁止通常用must not, 有时也用may not 语气较委婉。

　　"May (Can) I smoke here?" - "Yes, you may (can)." 或"No, you must not." 或 "You may not smoke here."

　　B. 表示责任、义务或必要时用must, 否定式只能用need not

　　"Must we hand in our homework today?" - "Yes, you must. No, you needn't."
