同学们，小学英语学习中的句型转换属于较难的题型，对大家的英语综合能力有一定要求。除了必须掌握基础的词汇外，还要对语法知识和句子语序有很好的掌握。很多同学在这种题型上失分比较严重，其实是因为大家没有掌握好方法。小学英语的句型转换就只有几种类型，只要掌握了方法，就不怕不会做题啦！同学们一定要好好学习哦！
一、肯定句改为否定句的方法 ：
1. 在be动词后加not。如：is not ， are not ， am not
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.
2. 在can，should， will等词后加not。
cannot(can’t)， should not(shouldn’t)， will not(won’t)；
如：
He can swim. → He can’t swim.
We should go there. → We shouldn’t go there.
I will go to Shanghai. →I will not go to Shanghai.
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。
如：
I like apples. → I don’t like apples.
He likes pink. →He doesn’t like pink.
I went to the park yesterday. →I didn’t go to the park yesterday.
3. some 改成any。
We have some books for the children. →
We don’t have any books for the children.
二、肯定句改为一般疑问句的方法：
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。
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?
There are some balls in the box. → Are there any balls in the box?
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。
如：
The cat can climb up the trees. → Can the cat climb up the trees?
I shall go swimming tomorrow. → Shall I go swimming tomorrow?
We will have a party. →Will you have a party?
I will clean my car. →Will you clean your car?
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。
如：
I go to the park on Saturday. →Do you go to the park on Saturday?
He gets up at seven in the morning. →Does he get up at seven in the morning?
They went to see the Great Wall yesterday.
→ Did they go to see the Great Wall yesterday?
Tom has some storybooks. →Does Tom have any stroybooks?
特别注意,以下情况some不能变成any
(1).希望得到肯定回答时。Can you give me some paper?
May I ask you some questions?
(2).在一些表示很委婉的疑问句中。
比如:Would you like some oranges?
这个疑问句型中就要用some,而不用any.在希望得到对方肯定答复的时候,仍用some.
(3).即征求别人意见的句子中.Could you give me some pears?
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.
—Are they students? → Yes ,they are. / No ,they aren’t.
—Is that a bird? →Yes, it is./ No, it isn’t.
—Do you go to school by bus? →Yes, I do. No, I don’t.
—Does she like her dress? →Yes, she does. / No ,she doesn’t.
—Can the dogs swim? Yes, they can. / No ,they can’t.
