一般疑问句
概念、句子结构、转换方法及练习
1、 什么是“一般疑问句”?
一般疑问句:用yes或no来回答的句子,这种问句用升调来朗读。
2、 一般疑问句的句子结构。
1. be动词+主语+表语?
例:Is he a teacher? Are they friendly?
2.情态动词+主语+动词原形+宾语?
例:Can you play the piano? Would you like some tea?
3.Do/Does/Did+主语+动词原形+其他?
例句:Do you like salad? Does she do housework at home?
三、陈述句变为一般疑问句的方法。
1. 找出句子中的第一个动词。
2.判断第一个动词是哪一类的词。
3. 根据动词的种类确定转化方式。
(1)是be动词,把be动词提前。
(2)是情态动词,把情态动词提前。
(3)是实义动词,在句首添加Do/Does/Did.
(4)一般情况下,有some就变成any,有第一人称就变为第二人称,句号变问号,其他单词照抄。
(5)注意,情态动词或Do/Does/Did后面的动词都要变为原形。
注意:
(01)当实义动词是原形时,就在句首添加Do
(02)当实义动词是第三人称单数时,就在句首添加Does
(03)当实义动词是过去形式时,就在句首添加Did

四、一般疑问句的回答方式(谁开头,谁回答)
肯定回答:Yes, 人称代词+句首动词的肯定形式
否定回答:No,人称代词+句首动词的否定形式
例:1. Is she a doctor? -Yes, she is. -No, she isn’t.
*is开头问,is来回答。
