陈述句变成一般疑问句

陈述句及一般疑问句的简单定义
何为陈述句? 陈述或者表达某个事实或状态。 (He is a student. I' m a doctor. The door is open. It is a beautiful city . She likes to swim . I like playing football. He works in a hospital . ) 何为一般疑问句? 要用YES 或者 NO 回答的问句。通常以系 动词或情态动词或助动词开头。(Are you a orstudent ? Is he a doctor ? Can I go to school on foot ? )

系动词、助动词、情态动词
系动词:小学阶段只需注意be动词(am, is ,are 及其对应的过去式was were。) 助动词:do , dose 及对应的过去式did。 情态动词:can \ shall \ will \ may 对应过去 式 could \ should \ would \ might 等。

将陈述句变成一般疑问句步骤
? 1 句中有be动词或情态动词的情况,直接 将句中的be动词或情态动词提前,若有 需要应在人称和数上发生相应变化。 ? a: 人称和数不变化 He is a student. Is he a student ? The door is open. Is the door open ?

b:人称和数上发生变化?.
? ⑴先将be动词或情态动词提前,⑵考虑人 称是否变化。 I'm a student. Am I a student ? 错错! 我是一个学生吗? 是不是学生自己知道,所以问句不成立, 变问句是别人问所以人称发生变化。 此时人称发生变化,数也发生变化。正确 应为: Are you a student ?

操练句子:
? I can go to school on foot . ⑴先将be动词或情态动词提前 Can I go to school on foot ? ⑵考虑人称是否变化。 Can you go to school on foot ? 在将陈述句 变一般疑问句时此时才完整。

如不是在陈述句变疑问句过程中,此句Can I go to school on foot , linda? 也正确。

? I will go to Beijing this weekend . ? Will you go to Beijing this weekend ?
? She is a nurse . ? Is she a nurse ? ? They are my parent . ? Are they your parent ? ? He is my father . ? Is he your father ?

2、句中无be动词和情态动词的情况
? 当陈述句中无be动词及情态动词时,根据句中 人称选用助动词,此时助动词置于句首,并注 意人称及动词的数有时也需要发生的变化。

? ⑴助动词的选用,主语为第一、二人称或复数 时用do,主语为第三人称或单数时用does。 ? I like playing football. ? Do you like playing football ?

例句:
I have a pet dog . Do you have a pet dog ? I go to school on foot . Do you go to school on foot ?

2、主语为第三人称时需注意
? 主语为第三人称时选用助动词does,此时谓语动 词部分发生相应变化。

? She likes to swim . ? Does she like to swim ?
? He works in a hospital . ? Does he work in a hospital ?

例句:
? ? ? ? ? She has a pair of beautiful eyes . Does she have a pair of beautiful eyes?

He teaches math in a school . Does he teach math in a school ?
