答：能用yes

/

no(或相当于yes

/

no)回答的问句叫一般疑问句。二、一般疑问句的结构

一般疑问句有两个家族。

第一家族为含be动词或情态动词的一般疑问句，其结构为：

be

+

主语

+

其它部分？

情态动词

+

主语

+

动词原形

+

其它部分？肯定回答用“Yes，主语+be\情态动词.”，否定回答用“No，主语+be\情态动词+not.”。be或情态动词和not可用缩写形式，主要有isn’t，aren’t，wasn’t，weren’t，can’t，mustn’t，needn’t等。

eg1.

问句：

Is

this

your

English

book？

肯答：

Yes，it

is.

否答：

No，it

isn`t.

eg2.

问句：

Are

these

your

English

books？

肯答：

Yes，they

are.

否答：

No，they

aren’t另一家族为含行为动词（或称为实义动词）的一般疑问句，其结构为：

助动词

+

主语

+

动词原形

+

其它？

肯定回答用“Yes,

主语+

do\does.”，否定回答用“No,

主语+do\does

not.”。助动词也常用缩写形式，主要有don’t，doesn’t，didn’t等。

eg3.

问句：

Do

your

parents

like

English？

肯答：

Yes，they

do.

否答：

No，they

don’t.如何将陈述句变为一般疑问句第一家族：含be动词或情态动词的句子

秘诀：一调二改三问号

一调：即把句中的be或情态动词调到主语前；

二改：改换主语称谓，即将句中的主语I\my

\mine\we\our\ours等第一人称分别改为相应的第二人称you\your\

yours等；

三问号：句末的句号改为问号。如：

.

I

am

an

English

teacher.

→

Are

you

an

English

teacher?

.

We

can

speak

English

fluently.

→

Can

you

speak

English

fluently?第二家族：含行为动词（或称为实义动词）的句子

秘诀：一加二改三问号

一加：即在句首加助动词Do或Does；

二改：1、把谓语动词改为原形；改换主语称谓（同第一家组）；

三问号：句末的句号改为问号。.

We

read

English

every

morning.

→

Do

you

read

English

every

morning?

.

Tom’s

father

listens

to

English

on

the

radio

every

evening.

→

Does

Tom’s

father

listen

to

English

on

the

radio

every

evening?

特别注意：对于第二家族一定要注意动词的还原，因为时态与数的变化已经体现在助动词上了。3、

加强记忆口诀：

“肯变一，并不难，can

或be提在前；

谓语若为行为动，do

或does句首用。”知识点2--------否定句（注意要和否定回答区分哦）把肯定句改成否定句分以下情况：  句中有be动词的，在be动词后加not； 句中有情态动词的（can ,should，must ，would），在情态动词后面加not；句中没有be动词和情态动词的，在动词前加don’t或doesn’t ①句中动词为原形的，加don’t.如： I like apples.→I don’t like apples. ②句中动词为三单式的，加doesn’t，并将三单式的动词还原成原形。 如：He likes apples.→ He doesn’t like apples.4、肯定句中的some在否定句中应改为any，and改为or，第一人称改为第二人称。 知识点3--------对划线部分进行提问

1．肯定句：2．否定句：3.一般疑问句及肯否定回答主语+be动词+….1)主语+be动词+not+….1）be动词+主语+…？Yes,主语+be动词./No,主语+be动词+not.Iamateacher.Iamnotateacher.Areyouateacher？--Yes,Iam./No,Iamnot.Mymotheristhin.Mymotherisnot/isn’tthin.Isyourmotherthin?--Yes,sheis./No,sheisn’t.Theyareinsects.Theyarenot/aren’tinsects.Aretheyinsects？--Yes.theyare./No,theyaren’t.2)主语+情态动词can+…2)主语+情态动词can+not+….2）情态动词can+主语+…？Yes,主语+情态动词can/No,主语+情态动词can+not

Hecanjump.Hecannot/can’tjump.Canhejump？--Yes,hecan./No,hecan’t.3)主语+动词+….3)主语+助动词do/does+not3）助动词do/does+主语+….动词原形+….动词原形？Yes,主语+助动词do/does.No,主语+助动词do/does+not.

Helikestoeatapples.

Hedoesn’tliketoeatapples.Doesheliketoeatapples？Yes，hedoes./No，hedoesn’t.

Weliketoeatapples.Wedon’tliketoeatapples.Doyouliketoeatapples？Yes，wedo./No，wedon’t.

二.祈使句：表示请求、命令、建议或劝告等的句子叫祈使句，主语you常省略。

1、肯定形式：一般以动词原形开头。Openthedoor,please.

2、否定形式：在句首谓语动词前加Don't。Don'tbelateforclass.三特殊疑问句（又叫wh-question）用特殊疑问词来提出问题的疑问句叫作特殊疑问句。特殊疑问词一般要放在句首。常用的疑问词有whatwho，whichhow等这些词都以wh开头（包括how）所以也叫作wh-question。特殊疑问句要求回答具体内容。不能用yes或no回答。结构：疑问词+一般疑问句。回答不能用yes/no(或相当于yes/no)回答的问句。答句的句式同肯定句句式：如：Whatcanyousee?Icanseeacat.Whatcanyouhear?Icanhearabus.Whatcanyoudo?Icansinganddance.Whatisit?It’sapanda.Whatdoyoulike?IlikeplayingfootballHowoldareyou?I’mten.一.将下列句子变成一般疑问句1MrWangisthirsty.__________________________?2.Theelephant’searsarelong.__________________________?3.Welikebirds._________________________?4.Hello,Iamhismother__________________________?5.Icansinganddance.___________________________?二将下列每组词各组成一句特殊疑问句1.(youarehow)._________________________?.2.(oldhowBenis)_________________________?3.colouriswhatyourshirt_________________________?4.(canseewhattheonyoudesk)________________________?5.(likewhatdoyou)_________________________?答案：一.1.IsMrWangthirsty?2.Aretheelephent’searslong3.Doyoulikebirds?4.Hello.Areyouhismother?5.Canyousinganddance?二.1.Howareyou?2.HowoldisBen?3.Whatcolourisyourshirt?4.Whatcanyouseeonthedesk?5.Whatdoyoulike?四、【课堂运用】【基础】【练习1】
