Section A 2d—3c教学设计(第二课时)

一般疑问句，否定句以及根据答句写问句的答题方法

改为一般疑问句：

先找be动词(am, is, are),或can,放在句子最前面，

如果没有则判断是否为第三人称单数(he/she /it/ Mike…)，是则把动词改为原形，句前加Does,其余照抄。

还不是，则句前加Do，其余照抄。

改为否定句：

方法和上面一样，先找be动词(am, is, are),或can,再后加not，其余照抄

不是则判断是否为第三人称单数(he/she /it/ Mike…)，是则把动词改为原形，人后加doesn’t,其余照抄

还不是，则人后加don’t，其余照抄

根据答句写问句的方法：

①用适当的疑问词（who , whose , what , how, how many , when ,why）来提问，

1.

②将剩余部分改为一般疑问句

（如果剩余部分为动词或动词短语，则用do代替，句前加what，再改为一般疑问句）

2.

如果句中没有

be 动词、助动词或情态动词，则根据谓语动词形式，借助

do 的相应形式放在句首。



如果谓语动词是原形，则借

do 

如果谓语动词是一般现在时第三人称单数形式，则借

does 

如果陈述句中有实义动词

have，且表示“有”时，借助动词

do、does



e.g

I have some friends in America. →

Do you have any friends in America? 需要注意的是：借

does 或

did 后，原句的谓语动词要变回原形。

e.g

Bill gets up at 6:30 every day.

→Does bill gets up at 6:30 every day?

The students saw a film yesterday.

→Did the students see a film yesterday?

注意：陈述句变一般疑问句注意的事项：



如果陈述句中有第一人称，则变问句时要变为第二人称。

e.g

I usually have lunch at school.

→ Do you usually have lunch at school?

My father is playing soccer.

→ Is your father playing soccer?



如果陈述句中有some，则变问句时要变为

any。

e.g

There is some water on the playground.

– Is there any water on the playground?
