1、陈述句变成一般疑问句:(1)如果句子中有 be动词(也就是说有 is,am,are,were,was 等)或是情态动词的(如 can,could,will,would等),把 be动词或情态动词直接提前,然后大写,剩下的照抄,然后末尾加上问号。(一提二改三问号) 如: He is a student.(他是一个学生。) 一般疑问句就是:Is he a student?.(他是一个学生吗?) They can play football.(他们会踢足球。) 变成 Can they play football?(他们会踢足球吗?) 注意:如果主语是 I或是 we的,一般疑问句一般情况下要把人称改为
2、 you。反之 you要改成 I,we,me 或 us。 如: I am a student. 一般疑问句就变成 Are you a student? We can help you.(我们能帮你。) 变成 Can you help me?(你们能帮我吗?) (2)如果没有 be动词和情态动词的,就要用助动词来提问,助动词有do,does,did。 而选择哪个助动词就要由陈述句中的动词时态或形式来决定了。(一加二改三问号)如: She speaks English very well.(她英语说得很好。) 一般疑问句变成 Does she speak English very well?(她英
3、语说得很好吗?) We finished our homework yesterday.(我们昨天完成作业的。) 变为 Did you finish your homework yesterday?(你们昨天完成作业的吗?) I go to school on foot.(我走路去上学。) 变为 Do you go to school on foot?(你走路去上学吗?) 选择好助动词后就可以把原句跟上去,要注意的是后面的动词要用原形了。如例子中的 speak,finish等。 另外,has got(have got 是“有”的意思) 中的 have或 has也是提前,即与第一种 be动词情态
4、动词的用法相同。 如: I have got a sister.(我有一个妹妹) 改为:Have you got a sister?(你有一个妹妹吗?) 练习题:将下列句子变为一般疑问句。1. I am a girl. _ 2. He is a cook. _ 3. They are teachers. _ 4. Lily can sing a song. _5.
