1、-PEP四年级英语语法-陈述句变一般疑问句-第 5 页四年级英语寒假教案第七讲一般疑问句一、什么是一般疑问句：用Yes或No作答的疑问句叫一般疑问句。1、以be动词、助动词或情态动词开头；例：Is your father a teacher?Does Mike like animals? Can Jenny speak French?2、往往读升调；3、译成汉语， “吗”，例如上面三句可分别译为：你父亲是老师吗？迈克喜欢动物吗？詹妮会说法语吗？二、如何将陈述句变成一般疑问句？要将陈述句变成一般疑问句，可以遵循下列步骤：1.看句中有没有be动词（am、is、 are、was、were）、助动词（

2、do、does、did、have、had）或情态动词（can、must、will、may等），如果有，将其提到句首，句末打上问号即可。例：It is a cat. Is it a cat? Toms father can play football. Can Toms father play the piano? 2.如果句中没有be动词、助动词或情态动词，则根据谓语动词的形式借助do的相应形式放在句首。具体方法是：如果谓语动词是原形，则借do；如果谓语动词是一般现在时第三人称单数形式，则借does；如果谓语动词是过去式，则借did. 需要注意的是，借does或did后，原句的谓语动词要变回原

3、形。 例：They go to school at 7 oclock. Do they go to school at 7 oclock? Bill gets up at 6:30 every day. Does Bill get up at 6:30 every day?三、陈述句变一般疑问句应注意的事项陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点：1.如果陈述句中有第一/二人称，则变问句时要互换。I/we you, my/our your例：I usually have lunch at school. Do you usually have lunch at school?

4、My father is playing soccer. Is your father playing soccer?2.如果陈述句中有some, 则变问句时往往要变成any 。例：There is some water on the playground. Is there any water on the playground?四、一般疑问句的回答一般疑问句往往采用简短回答，共由三部分（三个单词）组成，对这三部分的确定可以概括例下：1.第一个词：不是Yes就是No。（有时根据语气的不同，Yes可由Sure, Of course等代替.NO可由sorry 代替.）2.第二个词：问谁答谁。即答

5、语中的主语须与问句的主语一致（但必须用主格代词）。例：Does she clean her room every day? Yes, she does. Is Annas father a doctor? No，he isnt.如果主语是this that, 回答时用it 代替（如果问句中主语these, those, 回答时用they代替）。3.第三个词：用什么问，用什么答。即沿用问句中的引导词。Can Jim play soccer? Yes, he can. Does Mr. Bean speak English? Yes, he does.4.用No开头作否定回答时, 结尾要加上not

6、。因为回答必须是三部分，所以否定回答必须缩写，而肯定回答不能缩写。例: Do you have a pencil? Yes, I do. / No, I dont.Is Amy in Class 3? Yes, she is. / No, she isnt.或（No, shes not.）测测你自己真的懂了吗？将下列句子改成一般疑问句：并做肯定回答和否定回答1.
