陈述句变一般疑问句-课件【PPT演示稿】.ppt

陈述句变成一般疑问句: 陈述句变为一般疑问句,首先看句中有没有系动词 be或情态动词,如果有,把 be或情态动词直接提到句首就可以了;如果没有,要用助动词 do 或 does 来帮助。基本句式如下: Be + 主语+宾语+ 其他+ ? 情态动词+ 主语+ 谓语+ 宾语+ 其他+ ? Do(Does ) + 主语+ 谓语+ 宾语+ 其他+ ? Be + 主语+宾语+ 其他+ ? (1)如果句子中有 be动词(也就是说有 is,am , are 等) 把 be动词直接提前,剩下的照抄, 然后末尾加上问号。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?) He is a Mary is at She is My mother is in Is he a teacher? Is Mary at school? Is she fat? Is your mother in red? 情态动词+ 主语+ 谓语+ 宾语+ 其他+ ? 如果句子中有情态动词的(如 can, could, will, 等),把情态动词直接提前,剩下的照抄, 然后末尾加上问号。 They can play football. (他们会踢足球。) 一般疑问句就是: Can they play football? (他们会踢足球吗?) You can go He can You must do it She can do it by Can I go there? Ca n he swim? Must I do it now? Can she do it by herself? 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 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。) 一般疑问句就是: Can you help me? (你们能帮我吗?) 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 do, does 。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。如: She speaks English very well. 一般疑问句变成: Does she
