句型变换复习·陈述句变疑问句

1. 将陈述句改为一般疑问句

1) 若句中有系动词(be)、助动词、情态动词或have (作“有”讲)时，将其提到主语前，句末用问号。例如

He is a first-year student.

→Is he a first-year student?

I have a pencil-box.

→Have you a pencil-box?

2) 如果谓语动词是行为动词，则在主语前加Do(Does或Did)，再将动词还原成原形，在句末加问号。例如

He does morning exercises every day.

→Dose he do morning exercises every day?

They did some cleaning yesterday.

→Did they do some cleaning yesterday?

2. 将陈述句改为反意疑问句

反意疑问句是在陈述句后边加上一个简短问句，对陈述句所叙述的内容提出相反的疑问，这种句子就叫做反意疑问句。反意疑问句可以表示真实的疑问，也可以表示提问人的倾向、强调或反问。如果陈述句是肯定句时，后边的反意疑问句通常要用否定式；反之，如果陈述句是否定句时，后边的反意疑问句通常要用肯定式。陈述句和后边的反意疑问句的主语以及谓语动词的人称、数、时态通常要保持一致。例如

He is a teacher, isn’t he?

He speaks English, doesn’t he?

Mary won’t do it, will she?

回答反意疑问句和回答一般疑问句一样，肯定回答用“Yes, +肯定结构”；否定回答用“No, +否定结构”。这与汉语习惯有所不同，例如

—He’s a doctor, isn’t he? 他是医生，对吧？

—Yes, he is. 对，他是医生。(No, he isn’t. 不，他不是医生。)

—He isn’t a doctor, is he? 他不是医生，对吧？

—Yes, he is. 不，他是医生。(No, he isn’t. 对，他不是医生。)

在使用反意疑问句时，特别要注意以下几点

1. 在动词have当“有”讲时，可以有两种反意疑问句形式

He hasn’t any sisters, has he?

He doesn’t have any sisters, does he?

当have表示其他含义(如：经历、遭受、得到、吃……) 讲时，只有一种反意疑问句形式

You all had a good time, didn’t you?

He often has colds, doesn’t he?

They had milk and bread for breakfast, didn’t they?

2. 如果陈述句的谓语动词含有have to, had to时，反意疑问句通常用其他适当形式

We have to get there at 8 tomorrow morning, don’t we?

They had to take the early train, didn’t they?

3. need既可以作情态动词，又可以作实意动词，注意有两种反意疑问句形式

You needn’t hand in your paper today, need you?

You don’t need to hand in your paper today, do you?

4. 如果陈述句的谓语动词含有used to时，也可以有两种反意疑问句形式

He used to get up late, usedn’t / didn’t he?

5. 如果陈述句中出现never, seldom, hardly, few, little, nobody, no one, nothing 等含有否定意义的词时，反意疑问句通常要用肯定式，例如

She seldom goes to the concert, does she?

He hardly writes to you, does he?

He has few good reasons for staying, has he?

You have nothing else to say, have you?
