II. 一般疑问句的基本结构：

A . be/助/情态动词(be can do have will 等)+主语+谓语/表语+(其他)，句子要读升调; I like En glish. I do no t like En glish.

Do you like En glish? What do you like? She likes En glish.

Eg: Are they your friends ? Can you play basketball ? Can you swim to the other side ?

Does he go to school on foot ? Do you like En glish?

Have you locked the door ? Will you be free tonight ? 以上均可用yes、no 来回答。

B:述句亦可用作一般疑问句，多用在非正式文体中，句末有问号，用升调；

Eg: Somebody is with you ？He didn ' t finish the work You arefresh from America ，I

suppose ？

22.一般疑问句的回答：除yes、no 夕卜，也可用certainly , probably , perhaps , of course , all right ，with

pleasure 等代替yes，用never，not at all 等代替no ；

Eg: —Can you help me ? —Certai nly.

—Could you please make less noise ? —All right ，sir.

—Have you bee n there ? —Never.

33.一般疑问句的否定式：A. 一般结构：系/助/情态动词+not+主语;

也可为：系/助/情态动词+主语+not。

Eg: Do you not/Don

Are you not / Aren

Is he not / Is n Does Hele n not /Does n ? t you believe me? Is it not / Isn ? t it a lovely day?

? t you coming?Will you not /Won ? t you sit down? ? t he a doctor? Will he not /Won ? t he go with you?

? t Helen like chocolate海伦不喜欢巧克力吗？

B.否定疑问句并不单纯表示提问，它常常带有感情色彩；否定疑问句的完全式比简略式所表达的语气更强烈些；惊异、赞叹或责难等语气；暗示提问者期待着肯定的回答；表示邀请或建议；

Eg：Haven ' t you read the newspaper Wor? t he come ?他不来了啊？

Shouldn ' t we start now Wasn ' t it an interesting film ?

Wouldn ' t you like to go with me Won'? t you have a cup of coffee _____ ?

44.一般疑问句否定式的回答：否定的一般疑问句的答语中，yes的含义为“不”，no的含义为“是”，但在回答这类句子时，应该注意yes后接肯定结构，no后接否定结构，这和汉语习惯不同。Eg：—Are you n ot Mr Smith ? —Yes，I am.丕，我是//—No，I am not.是的，我不是

—Haven ? t you read this book before Yes，l?have.不，我读过// —No，I haven ? t. 是的,我没有Don ? you play chess ? —Yes ，I do.不，我下棋//—No ,1 don ? t.是我不下棋。

教你一招：在这样的答语中，只要根据实际情况来判断，如果事实上是，就用肯定的结构，前面接yes;如果事实上不是，就用否定结构，前面接no ；但此时的yes、no应翻译成反义的中文。

2. 特殊问句special questions : wh-questions 型问句，when. where. what. who. why. which.

A .特殊疑问词+ 一般疑问句；即特殊疑问词+be/助/情态动词+主语+谓语/表语+（其他）.

Eg: Who is it on the phone ?谁来的？How many oran ges can you see in the picture ?
