期末考试必备：否定句、一般疑问句和特殊疑问句

一、 肯定句变否定句

1> 看肯定句中有没有be动词（am、is、 are、 was、 were）或情态动词（can），如果有，直接在其后加not，其余照抄就可以。

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

2、在can，等后加not。如：can not(缩写 can’t)

2> 如果句中没有be动词或情态动词，变否定要找助动词do的相应形式（do、does、did）帮忙，且原句的谓语动词要变回原形。

否定句中and，some与any的用法

1. 否定句中and要变为or

2. 否定句中some要变为any

二、一般疑问句

1、定义: 以be动词/助动词/情态动词开头的句子叫一般疑问句。

2、特点：用yes/no回答。

例：Is your father a teacher? 翻译：你的父亲是一名老师吗？ 结构：Be动词+主语+其他

Does Tom like apples? 翻译：汤姆喜欢苹果吗？ 结构：助动词+主语+动词原形+其他

Can Jenny speak English? 翻译：珍妮会说英语吗？ 结构：情态动词+主语+动词原形+其他

3、陈述句变成一般疑问句的方法：

1）看陈述句中有没有be动词（am/is/are/was/were）或情态动词（can），如果有，将其提到句首，其余照抄，句末打上“？”即可。

例：It was rainy yesterday.

变一般疑问句→

Tom's father can play the piano.

变一般疑问句→

2）如果句中没有be动词或情态动词，句首加do的相应形式（do、does、did），其余照抄，且原句的谓语动词要变回原形。

例：They go to school by bike. →

Bill gets up at 6:30 every day. →

The students saw a film yesterday. →

注：1.如果陈述句中有第一人称，则变问句时要变为第二人称。

I usually have lunch at school.

2.如果陈述句中有some,则变问句时往往要变成any。

There is some water on the playground.

4、一般疑问句的回答。

例：---Does she clean her room every day? ---Yes, ________.

---Is Anna′s father a doctor? ---No，________.

---Can she dance? ---Yes,________.

如果问句主语是 this that,回答时用____代替；若问句主语是these, those,回答时用 _____代替。

--Is this your bag? --Yes, ________ ./ No,________ .

--Are those your books? --Yes, ________. / No, ________.

练习：肯定句变一般疑问句

2. These cats are crying.

3. They can swim.

4. I went to school on foot.

5. His father goes to work by bus.

7. Kitty is leaning English now.

8. The two boys under the tree were hungry.

9. Lingling and Amy watch television at night.

10. I can finish my homework by myself.

三、特殊疑问句

1、定义：以 特殊疑问词 开头，对句中某一成分提问的句子叫特殊疑问句。常用的特殊疑问词有：what ,who, whose, which, when, where, how, why等。

2、结构：特殊疑问句=特殊疑问词+一般疑问句

3、语序：

１>．如疑问词作主语或是对主语提问，其语序是陈述句的语序：疑问词＋谓语动词＋其他成分？

如：1)Who is singing in the room﹖ 2)Where is he?

２>．如疑问词作其他成分，即对其他成分提问，其语序是：疑问词+助/be/情+主语+其他

如： 1)what class are you in﹖ 2)What does she look like﹖

注：回答特殊疑问句时，不能用yes／no，即问什么答什么。

如：Where's the restaurant﹖ It is near the station．

4、对划线部分提问做题方法：

四字口诀：找词变句

找词：找划线部分对应的特殊疑问词 变句：将剩余部分变问、

练习：就画线部分提问
