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
一般疑问句有两种回答，即：肯定回答和否定回答。其中，肯定回答用yes,否定回答用no。语句顺序为：Yes + 主语+ am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn’t/ aren’t/wasn't/weren't.|can't.|don't/doesn't/didn't |.。如：
—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 ?
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.
英语肯定句改为否定句、陈述句改为一般疑问句的方法和诀窍㈠肯定句变为否定句的方法——⑴加；⑵变 ⑴“加”——是指加not。加not的规则是：原句中有“情助be”时则直接在“情 助be”后加not（not可与“情助be”缩写）；原句中没有“情助be”时则需要另加助动词do/does/did, 然后在助动词do/does/did后加not（not可与助动词do/does/did缩写）。 助动词do和does用于一般现在时，did用于一般过去时。 ⑵“变”——是指变化某些需要变化的词（因为某些词只能用于肯定句或只能用 用于否定句）。如：some→any（someone→anyone，something→anything，somewhere→anywhere）；and→or；too/also→either[′aie?; ′i: e?]；a lot of→many/much等。另外，使用助动词does/did帮助否定时，原来的谓语动词要恢复原形。 例：1）He can swim. →He can’t swim. 2）He will（将，要）swim. →He won’t(will not) swim. 3）He is a good swimmer. →He isn’t a good swimmer. 4）I have some English books. →I don’t have any English books. 5）She can sing and dance. →She can’t sing or dance. 6）Li Lei’s father has a lot of money. →Li Lei’s father doesn’t have much money. 7）He went to Shanghai last week. →He didn’t go to Shanghai last week. 说明：大多数英语肯定句改为否定句都符合上述规则，但也有一些特殊的情况不符合上述规则，在以后的学习中会学到，要注意积累。如： 例：1）He saw（看见）someone in the room. →He didn’t see anyone in the room. 也可改为：→He saw no one in the room. 2）He always（总是，一直）plays computer games. →He never（从来不）plays computer games. 3）Everyone here likes him. →No one here likes him. ㈡陈述句变为一般疑问句的方法——⑴提；⑵变 ⑴“提”——是指把“情助be”提到主语之前，即句首。提前“情助be”的规则 是：原句中有“情助be”时则直接提前“情助be”；原句中没有“情助be”时则需要另加助动词do/does/did放于句首，助动词do和does用于一般现在时，did用于一般过去时。 ⑵“变”——是指：①变化某些需要变化的词。如：some→any（someone→anyone， something→anything，somewhere→anywhere）。但是，不像肯定句变为否定句那样，陈述句变为一般疑问句时and、too/also、a lot of等不必改变。陈述句变为一般疑问句时，习惯上第一人称改为第二人称（见下面例4））。另外，使用助动词does/did帮助提问时，原来的谓语动词要恢复原形。②变句首字母大小写。陈述句变为一般疑问句时，要注意句首字母大小写的改变。③变标点。陈述句变为一般疑问句时句号要改为问号。 例：1）He can swim. →Can he swim? 2）He will（将，要）swim. →Will he swim? 3）He is a good swimmer. →Is he a good swimmer? 4）I have some English books. →Do you have any English books?

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:
肯定句变否定句的基本方法 一、如果谓语中有情态动词、助动词或be，直接在它们后面加not构成否定句。 1.在含系动词be、助动词be, have, has, will, would, shall, should等之后直接加not，构成否定句。如： He is there. — He is not there. 他不在那儿。 I have finished my work. — I have not finished my work. 我的工作还没完成。 She will agree with you. — She will not agree with you. 她不会同意你的意见。 He will not go there. 他不会那里。 I am not a teacher. 我不是教师。 2.否定含情态动词的句子： a.在情态动词can, could, may, might, must, need, dare, had better, would rather的句子之后直接加not。如： (1) He can say so. — He can not say so. 它不会那样说。 (2) Students must smoke. — Students must not smoke. 学生不允许抽烟。 (3)You’d better go there now.—You’d better not go there now. 现在你最好不要去那里。 (4)I’d rather tell you the truth.—I’d rather not tell you the truth. 我倒想不告诉你真相。 (5) He dared ask his parents for money again. — He dared not ask his parents for money again. 他不敢向父母亲要钱。 I can not dance. 我不会跳舞。 b.在含情态动词ought to的句子，在ought to中的to前面加not，构成否定句。如： (1) You ought to bother him. — You ought not to bother him. 你不应该去麻烦他。 (2) You ought to waste your time. — You ought not to waste your time. 你不应该把时间浪费了。 c.在含情态动词used to的句子，可在used to中的to前面加not；也可在used前面加did not，同时将used 改为use。如： (1) He used to smoke in the past . — He used not to smoke in the past. 他过去不常抽烟。 (2) He used to live here. — He did not use to live here. 他原来常不住这里。 d.在含情态动词have / has / had to的句子，在have / has / had to前面加do not的适当形式, 同时将has / had 改为have。如： (1) You do have to stay here after school. — You do not have to stay here after school. 你不必放学后还呆在这里。 (2) He had to go to work yesterday. — He did not have to go to work yesterday. 他昨天不必去上班。 二、如果谓语中没有情态动词、助动词或be，在动词之前加do not (一般现在时第三人称单数用does not,过去时用 did not，并将原来的谓语动词改为原形) 。 (1) He likes classic music. — He does not like classic music. 他不喜欢古典音乐。 (2) She played table tennis yesterday afternoon. — She did not play table tennis yesterday afternoon. 她昨天下午没有打乒乓球。 You don’t look well today.你今天气色不好。 She does not know what to do. 她不知道做什么。
陈述句变为否定句 1.如果陈述句中有be动词（am , are, is, was, were）,就在be动词后 面直接加not。 I am a student. → I am not a student. You are sad. → You are not sad. She is a good girl. → She is not a good girl. He is a good boy. → He is not a good boy. Yesterday was Monday. → Yesterday was not Monday. The students were busy yesterday. → The students were not busy yesterday. 2.如果陈述句中有情态动词（can must should may will等），就在情 态动词后面直接加not。 I can swim. →I can not swim. You will go to the park. → You will not go to the park. 3.如果陈述句中没有be动词也没有情态动词（就是实意动词），就 需要借助助动词（do, does, did）来帮助否定。 ①当句中的动词是原形时，加don’t I like English. → I do not like English. You have dinner. → You do not have dinner. ②当句中的动词是第三人称单数时，加doesn’t ，再加动词原形 She likes singing. →She doesn’t like singing. She does her homework. → She does not do her homework. (特例)
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)
否定句变换口诀 1. 变否定，找be、 can ， be、can后边加not， 2. 无be无can找动词，动词前边加don't/doesn’t，后面动 词用原形。 【典型例题】 1. David watches TV every evening.（改为否定句） 2. She is buying some food in the supermarket（改为否定句） 3. He can play the piano.（改为否定句） 一般疑问句变换口诀 1. 一般问，找be、 can ， be、 can提前用问号； 2. 无be无can借用do（三单does）, 放到句首要大写。 【典型例题】 1. This is my toy car.（改为一般疑问句） 2. He can play basketball.（改为一般疑问句） 3. Jack speaks English very well. （改为一般疑问句） 对划线部分部提问口决 划线问，先把原句变疑问，找准特殊疑问词，放在句首去划线，动词词组do 代替，时态人称要注意。 【典型例题】 1. The children are flying kites in the park. （对画线部分提问） 2. There are ten books in the bag.（对画线部分提问） 3. She is a nurse. （对画线部分提问）
一、按要求完成句子（要求：A：改为一般疑问句 B：改为否定句） 1. I am a student.→A: B: 2. They are English cars. →A: B: 3. This is a pencil-box. →A: B: 4. Its name is Polly. →A: B: 5. Jim is at school. →A: B: 6.
