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 + ？（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，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？）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。
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，完成时态和have、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？）完成时的例子：I have ever been to Beijing.(我曾经去过北京Have you ever been to Beijing?（你曾经去过北京吗？）陈述句变为一般疑问句基本上应该就这样的吧。
这可都是我自己总结的哦。
因为自己是老师，所以也就是这么教学生的。
英语怎样做否定句，一般疑问句，对划线部分提问，有怎样的技巧，举几个例子一、否定句1.主语+be动词+表语结构变否定句，直接在be动词后面加个not就可以了。
Mr. White is a very good teacher.-->Mr. White is not a very good teacher.2.主语+动词+其他当此句为一般现在时，在动词之前加don't或doesn't（第三人称单数形式）,并将动词变为原形就可以了He loves playing football with his friends.-->He doesn't love playing football with his friends.当此句为过去时，在动词之前加didn't，并且把动词变为原形Tom's sister graduated from high school last year.-->Tom's sister didn't graduate from high school last year.3.主语+情态动词+动词+其他在情态动词后面加not就可以了I can drive a car.-->I cannot drive a car.4.主语+have/has+动词过去分词+其他在have/has后面加not就可以了The students have done their homework.-->The students have not done their homework.二、一般疑问句1.主语+be动词+表语结构变一般疑问句，把be动词提前，句子就变成 be动词+主语+表语结构？Mr. White is a very good teacher.-->Is Mr. White a very good teacher?2.主语+动词+其他当句子为一般现在时，在句首加do或does，并且把动词变为原形，句子变成Do/Does+主语+动词原形+其他？He loves playing football with his friends.-->Does he love playing football with his friends?句子为一般过去时，在句首加did，句子变成 Did+主语+动词+其他？Tom's sister graduated from high school last year.-->Did Tom's sister graduate from high school last year?3.主语+情态动词+动词+其他将情态动词提前，句子变成情态动词+主语+动词原形+其他？I can drive a car.-->Can you drive a car?4.主语+have/has+动词过去分词+其他将have/has提前，句子变成have/has+主语+动词过去分词+其他The students have done their homework.-->Have the students done their homework?三、对划线部分提问先找出划线部分在句子中所占得成分，找到对应的疑问词，将疑问词写在句首，再将原句变成一般疑问句，却掉划线的部分，写在疑问词后面就可以了。
Tom bought a new computer from the store yesterday.若划线部分为Tom，Tom 是个人，且作主语，则疑问词应选Who，此句应该为Who bought a new computer from the store yesterday?若划线部分为a new computer，划线部分为物，则疑问词为what，此句应为What did Tom buy from the store yesterday?若划线部分为from the store,则疑问词应为Where，表示地点，此句应为 Where did Tom buy a new computer yesterday?若划线部分为yesterday,则疑问词为When，表示时间，此句应为 When did Tom buy a new computer from the store?英语怎样变句型一般疑问句否定句反问句肯定句画线提问0分1. 由连系am，is，are构成的句子：变一般疑问句时把am，is，are提到句子的前面，句尾用问号即可。
变否定句时直接在am，is，are后面加not即可。
例如：肯定句:He is a student.一般疑问句: Is he a student?否定句: He is not a student.反问句: He is a student, isn't he?He isn't a student, is he?画线提问: 对he提问: Who is a student?对 a student 提问: What is he? or What does he do?2. 由情态动词can, may, should等构成的句子: 变一般疑问句时把can,may,提到句子的前面,句尾用问号即可.变否定句时直接在can,may,后面加not即可. 例如:肯定句: She can swim.一般疑问句: Can she swim?否定句: She can not swim.反问句: She can swim, can't she?She can not swim, can she?画线提问: 对she提问: Who can swim?对swim提问: What can she do?3. 由行为动词构成的句子: 需要加助词do或does. 变一般疑问句时把do/does放在句子前面. 例如:肯定句: They play football after school.一般疑问句: Do they play football after school?否定句: They don't (do not play football after school.反问句: They play football after school, don't they?They don't play football after school, do they?画线提问: 对they提问: Who play football after school?对play football提问: What do they do after school?对after school提问: When do they play football?小学英语语法提高/一般疑问句和特殊疑问句疑问句可再分为一般疑问（General question）和特殊疑问（Special question）两种。
1.一般疑问：用be或助动词或情态动词置于句首，并以“Yes，…”，或“No，…”或相当于yes / no回答的问句称为一般疑问句.2. 含系动词be的一般疑问句的构成具体地说,am 只能跟在第一人称的单数 I 后面,are 搭配 you, 不管是单数还是复数,is 跟在第三人称单数 he, she 后面,be 动词的基本意思：是如：I'm in Class 2, Grade 1. →Are you in Class 2, Grade 1? 你是在一年级二班吗?(如遇第一人称，最好将其置换成第二人称It's a map of China. →Is it a map of China? 这是一幅中国地图吗？be 或 have（有）置于句首来表达疑问，例：Am I wrong again? （我又错了？）Yes, you are （wrong again）. （是的，你又错了。
