六年级英语肯定句改否定句

一、肯定句改否定句的方法：

1、在be动词后加not。如：is not ， are not ，am not， was not， were not；

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：

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

—Are you an English teacher?→Yes, I am. /No, I am not.

—Is that a bird? →Yes, it is./ No, it isn’t.

三、对划线部分提问

“就划线部分提问”是小学阶段英语学习的

难点，但是一旦掌握了规律，就变得容易多了。小学英语对划线部分提问之答题口诀：

一代：用正确的疑问词代替划线部分。

二移：把疑问词移至句首

三倒：颠倒主谓语，但对主语或其定语提问时除外（some 改成any，I改成you，my改成your），

四抄：照抄句子剩余部分。

☆总结关键就是：“特殊疑问词+一般疑问句”(即：先根据划线部分找到特殊疑问词；再把没划线的部分变成一般疑问句的语序。)

★特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种：

1.划线部分是“事或物”，特殊疑问词用what

---What is this?

I often play football on Saturdays .

---What do you often do on Saturdays ?

2.划线部分是“人”，特殊疑问词用who

３、划线部分是“地点”，特殊疑问词用where

４、划线部分是“时间”，特殊疑问词用what time

或when

usually get up?

５、划线部分是“年龄”，特殊疑问词用how old

father ?

６、划线部分是“职业”，特殊疑问词用what

７、划线部分是“颜色”，特殊疑问词用what colour

hat？

8. 划线部分是“数量”，特殊疑问词用how many或how much

you see ?

There is some milk in the glass. ---How much milk is there in the glass ?

９、划线部分是“多少钱”，特殊疑问词用how much

pen ?

１０、划线部分是“形容词性物主代词或名词性物主

以下口诀要牢记：

1．问“谁”用who；

2．问“谁的”，用whose；

3．问“地点哪里”，用where；

4．问“原因”，用why；

5．问“身体状况”，用how；

6．问“方式”，用how；

7．问“年龄”，用how old；

8．问“多少”，用how many；

9．问"价钱”用how much；

10．问“哪一个”，用which ；

11．问“什么”，用what；

12．问“职业”，用what；

13．问“颜色”，用what colour；

14．问“星期”，用what day；

15．问什么学科，用what subject；

16．问“什么时候”，用when;

17.问几点用What’s the time?或 What time is it?

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.

我们现在学过的大多数句型，在一般情况下（就是不排除有特殊情况）都可以用简单的公式来记忆。

1.肯定句变否定句

1) 主语+be动词+….

*I am a teacher.→I am not a teacher.

He is a doctor. →He is not a doctor. They are students. →They’re not students.

2) 主语+do动词的不同形式+….

I play computer games everyday. →I don’t play computer games everyday.

He plays computer games everyday. →He doesn’t play computer games everyday

We played computer games yesterday.→ We didn’

t play computer games everyday

2肯定句变一般疑问句

1）问：be动词+主语+…?

Yes, I am. No, I am not.

He is a doctor.→Is he a doctor?

Yes, he is. No, he is not.

They are students. →Are they students?

Yes, they are. No, they are not.

2) 问：助动词+主语+do动词的原形+…?

答：Yes, 主语+助动词。/No, 主语+助动词+not.

I play computer games everyday.

→Do you play computer games everyday? Yes, I do. No, I don’t.

He plays computer games everyday.

→Does he play computer games everyday? Yes, he does. No, he doesn’t.

We played computer games yesterday. →Did you play computer games yesterday? Yes, we did. No, we didn’t.

肯定句及祈使句变否定句

中考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 cannot sing this song and that one. 正；He cannot 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 already. 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。 6. Let’s do it.

小学英语句型转换之肯定句变否定句教学设计

小学英语句型转换之肯定句变否定句教学目标：帮助学生更好的了解句型，及掌握肯定句转换否定句的方法。教学重难点：了解肯定句变否定句的方法及特殊情况。教学过程：一、了解概念：什么是肯定句和否定句二、了解肯定句变否定句的方法 1、方法1：1.含“be动词和情态动词”型，直接在be动词或情态动词后加not,其它照抄不变。 be动词包括：am,is,are,was,were. 常见的情态动词有：can,could,would,will,may等等。例句：（1）、I am a student.→I am not a student. （2）、He is a boy.→He is not/isn't a boy. （3）、I can speak English.→I can not/can't speak English. 2、方法2:含“实意动词”型，转换否定句时，记住五个字“一加一还原”的原则。“一加”即在实意动词前加助动词的否定don't,doesn't或didn't。“一还原”即把句中的实意动词变回原形。注意：在一般现在时中，当主语是第一、二人称或复数时，加don't来否定；当主语是第三人称或单数时，加doesn't来否定;在一般过去时中，一律用didn't 来否定。例句：（1）、I like apples.→I don't like apples. （2）、He likes apples.→He doesn't like apples. （3）、She worked last night.→She didn't work last night. 3、在肯定句变否定句中的特殊情况:

英语肯定句改否定句的方法

肯定句改否定句的发： 1．看句子中有没有系动词或情态动词，如果有，就直接在系动词或情态动词后加not。例如：They were busy yesterday.(他们昨天很忙)，句子中有系动词were，改为否定句时就直接在系动词were 后加not，改为They were not busy yesterday.（他们昨天不忙）。再例如You should stand here(你应该站在这儿)，改为否定句，在情态动词should后加not，改为You should not stand here.(你不应该站在这儿) 2.句子中如果没有系动词或情态动词，就在实意动词前（主语后）don′t或doesn′t 或didn′t（根据实意动词的形态确定），实意动词必须变回原形。例如：The children feel happy.(孩子们感到快乐)，动词是原形形式的feel,所以在动词前加don′t，改为否定句：The children don′t feel happy.（孩子们感到不快乐）再例如：She takes up the phone(她拿起电话)，动词是单三形式的takes,所以在动词前加doesn′t，同时必须把句子中的takes变回原形take，改为否定句：She doesn′t take up the phone(她没拿起电话) 再例如：He told me a story(他给我讲了一个故事)，动词是过去式形式的told,所以在动词前加didn′t，同时必须把句子中的told变回原形tell，改为否定句：He didn′t tell me a story(他没有给我故事)
