同學(xué)們，小學(xué)英語(yǔ)學(xué)習(xí)中的句型轉(zhuǎn)換屬于較難的題型，對(duì)大家的英語(yǔ)綜合能力有一定要求。除了必須掌握基礎(chǔ)的詞匯外，還要對(duì)語(yǔ)法知識(shí)和句子語(yǔ)序有很好的掌握。很多同學(xué)在這種題型上失分比較嚴(yán)重，其實(shí)是因?yàn)榇蠹覜](méi)有掌握好方法。小學(xué)英語(yǔ)的句型轉(zhuǎn)換就只有幾種類型，只要掌握了方法，就不怕不會(huì)做題啦！同學(xué)們一定要好好學(xué)習(xí)哦！

一、肯定句改為否定句的方法 ：

1. 在be動(dòng)詞后加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等詞后加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.上述都沒(méi)有的，在動(dòng)詞前加助動(dòng)詞否定形式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、肯定句改為一般疑問(wèn)句的方法：

1.把be動(dòng)詞放在句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句點(diǎn)改成問(wèn)號(hào)。

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，）句點(diǎn)改成問(wèn)號(hào)。

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. 上述都沒(méi)有的，在句首請(qǐng)助動(dòng)詞Do/Does/Did幫忙，剩下的照抄，（some 改成any，I改成you，my改成your，）句點(diǎn)改成問(wèn)號(hào)。

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?

特別注意,以下情況some不能變成any

(1).希望得到肯定回答時(shí)。Can you give me some paper?

May I ask you some questions?

(2).在一些表示很委婉的疑問(wèn)句中。

比如:Would you like some oranges?

這個(gè)疑問(wèn)句型中就要用some,而不用any.在希望得到對(duì)方肯定答復(fù)的時(shí)候,仍用some.

(3).即征求別人意見(jiàn)的句子中.Could you give me some pears?

4.就一般疑問(wèn)句回答

一般疑問(wèn)句有兩種回答，即：肯定回答和否定回答。其中，肯定回答用yes,否定回答用no。 語(yǔ)句順序?yàn)椋?/p>

Yes + 主語(yǔ) + am /is/ are/was/were/can/do/does/did

No + 主語(yǔ)+ 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.
