六年级英语肯定句变一般疑问句专项一、什么是一般疑问句？一般疑问句是指通过提问方式来表达对某件事情的真实性或可行性的疑问句。
主要以动词be、助动词do/does/did或情态动词can/could、may/might、shall/should、will/would、must等开头。
二、一般疑问句的基本结构1. 动词be开头一般疑问句的基本结构是：Be+主语+其它？如:- Is he a student?- Are they playing soccer?2. 助动词do/does/did开头一般疑问句的基本结构是：助动词+主语+动词原形+其他？如：- Do you like bananas?- Does she go to school?3. 情态动词开头一般疑问句的基本结构是：情态动词+主语+动词原形+其他？如：- Can you swim?- Should we start now?三、肯定句变一般疑问句的步骤1. 找到句子中的动词，判断是谓语动词还是非谓语动词。
2. 如果是谓语动词，将其移到主语前面，并添加适当的助动词或情态动词。
3. 如果是非谓语动词，找到句子的谓语动词，并按照第二步的规则进行转换。
4. 将句子中的句号改为问号。
我们通过一些例子来演示如何将肯定句变为一般疑问句。
She is a teacher.Is she a teacher?They are playing soccer.Are they playing soccer?He can swim.Can he swim?I like ice cream.Do you like ice cream?We have finished our homework.Have you finished your homework?五、注意事项1. 一般疑问句可以用短答语回答，短答语为"Yes, 主语+动词原形"或"No, 主语+助动词/情态动词+not+动词原形"。
→小学英语专项复习肯定句变一般疑问句1、含系动词be的一般疑问句构成具体地说，就是当陈述句中有am/is/are时，可直接将它们提至主语前，但如遇第一人称，最好将其置换成第二人称。
如：I’m in class 2,Grade 1.→Are you in class 2,Grade 1? 你是在一年级二班吗？2、含情态动词的一般疑问句的构成一般疑问句面前人人平等；情态动词与am/is/are一样，也可直接将它们提至主语前，所以问题就迎刃而解了。
如：I can spell it.→Can you spell it? 你会拼写它吗？3、含实义动词的一般疑问句的构成含实义动词的一般疑问句的构成稍微有点讲究，要在句首加do；如逢主语为第三人称单数，谓语动词为一般现在时单数第三人称形式“V-(e)s”时，奉does为座上宾并要变回原形（如has→have,likes→like等）；有时陈述句中的some还要变成any等。
如：She lives in Beijing. →Does she live in Beijing? 她住在北京吗？I like English. →Do you like English? 你喜欢英语吗？4、少数口语化的一般疑问句如问一个与前文相同的问句时，可省略成“And you?”或“What/How about...?”等；甚至只抓关键词，读作升调。
如：You pen? 你的钢笔？强化训练：将下列句子变成一般疑问句1.She is doing some cleaning._____ she doing _____ cleaning?2.They were watching TV at this time yesterday.___ they ___TV at this time yesterday?3.she goes bicycling twice a week.___ she ___ bicycling twice a week?4.she has to clean the classroom every day.___ she ___to clean the classroom every day?5.she does morning exercises every day.___ she ___ morning exercises every day?6.we did morning exercises yesterday.___ you ___morning exercises yesterday?7.jim used to be a policeman.___ jim ___ be a policeman.8.i am from Canada.___ ___ from Canada?9.she is looking for her dog.___ she ___ for her dog?10.
