we have to do our homework first变一般疑问句?
将“We have to do our homework first.(我们得先做作业。)”改为一般疑问句是:Do you have to do our homework first?(你们必须先做作业吗?)
句型转换:陈述句变成一般疑问句
一、什么是一般疑问句?
一般疑问句用于对某一情况提出疑问,通常用 YES 和 NO 来回答,读时可用声调加强语气。
二、变一般疑问句的方法:
A:把句子中的be动词提到句首(be动词包括:am is are)
例如:
I am a student.→Are you a student?
She is a teacher.→Is she a teacher?
They are good friends.→ Are they good friends?
B:把句子中的情态动词提到句首(情态动词包括can may must will should等)
例如:
She can play football.→ Can she play football?
I will help you. → Will you help me?
C:如果句子中没有be动词和情态动词,就要在句首加上助动词帮助其变成一般疑问句。(情态动词包括 do 和 does)
主语是第一、二人称和复数人称时在句首加上Do;
主语是第三人称单数形式时加Does。加上Does之后,原来句子中的三单形式要还原。
人称:第一人称:单数:I 复数:we
第二人称:单数:you 复数:you
第三人称:单数:she、he、it 以及人名 复数:they
例如:
You have a friend. → Do you have a friend?
She likes apples. → Does she like apples?
Amy does her homework at home.→ Does Amy do her homework at home?
注意:
1.句号变问号;
2.句子中的第一人称和第二人称互换;
I can help you . → Can you help me?
3.some→ any;
I have some apples. →Do you have any apples?
4.动词的三单形式还原问题。
She goes to school on foot. →Does she go to school on foot?
