初中生必学：英语一般疑问句的构成与应用

在英语学习中，一般疑问句是一个非常重要的知识点。掌握好一般疑问句不仅能帮助我们更好地理解英语对话，还能在考试中取得更好的成绩。今天，我们就一起来学习一般疑问句的构成和回答方式。

一般疑问句是用提问的方式来询问事物或确定某种情况是否属实，要求对方给予肯定或否定回答，读时一般用升调。一般疑问句的构成通常是在句首加be动词（am/is/are）、助动词（do/does/did）或情态动词（can/may/must/will等），回答常用“Yes/No.”来回答。

1. 有be动词的情况

当句子中有be动词（am/is/are）时，只需将be动词移到主语前面即可构成一般疑问句。

例如：

• She is a teacher. → Is she a teacher?
• They are playing soccer. → Are they playing soccer?

回答方式：

• Yes, 主语+be.
• No, 主语+be+not.

2. 有情态动词的情况

当句子中有情态动词（can/may/must/will等）时，将情态动词移到主语前面即可构成一般疑问句。

例如：

• He can speak English. → Can he speak English?
• You must finish your homework. → Must you finish your homework?

回答方式：

• Yes, 主语+情态动词.
• No, 主语+情态动词+not.

3. 没有be动词和情态动词的情况

当句子中没有be动词和情态动词时，需要在主语前添加助动词do、does或did，并将谓语动词变为原形。

例如：

• He watches TV every day. → Does he watch TV every day?
• They went to the park last week. → Did they go to the park last week?

回答方式：

• Yes, 主语+do/does/did.
• No, 主语+do/does/did+not.

一般疑问句的回答通常有两种方式：肯定回答和否定回答。

• 肯定回答：Yes, 主语+be/助动词/情态动词.
• 否定回答：No, 主语+be/助动词/情态动词+not.

例如：

• Is she a teacher? → Yes, she is. / No, she isn't.
• Can he speak English? → Yes, he can. / No, he can't.
• Did they go to the park? → Yes, they did. / No, they didn't.

1. 人称变化：在将陈述句变为一般疑问句时，如果句中有第一人称，如I、we，要变为第二人称，即you；同样地，第二人称在一般疑问句中要变为第一人称。

   • I am a student. → Are you a student?
   • You can play the piano. → Can I play the piano?

2. some和any的用法：在疑问句中，通常将some改为any。

   • There is some water in the bottle. → Is there any water in the bottle?

3. 谓语动词的变化：在没有be动词和情态动词的情况下，要使用do/does/did，并将谓语动词还原为原形。

   • She likes apples. → Does she like apples?
   • They played basketball yesterday. → Did they play basketball yesterday?

1. 将下列句子改为一般疑问句，并做肯定和否定回答。

   • Jenny goes to the library on Sunday.
   • Does Jenny go to the library on Sunday?
   • Yes, she does. / No, she doesn't.

2. 句型转换：

   • Those children are students. → Are those children students?
   • We can see a lot of girls in the picture. → Can we see a lot of girls in the picture?
   • They will go to England for a visit. → Will they go to England for a visit?
   • The young men aren't having a party. → Are the young men having a party?
   • She has been to Shanghai already. → Has she been to Shanghai yet?

3. 就划线部分提问：

   • Arthur runs fastest in his class. → Who runs fastest in his class?
   • Bob's painting was put up on the wall of our school. → Whose painting was put up on the wall of our school?
   • Chapter One is very difficult to learn. → Which chapter is very difficult to learn?
   • Mary does her homework after supper in the evening. → What does Mary do after supper in the evening?
   • He has borrowed four books from the school library. → How many books has he borrowed from the school library?
