1、一般疑问句用Yes或No作答的疑问句叫一般疑问句。结构是be动词（am /is /are ) /助动词/情态动词+主语+其他成分 通常回答为：肯定：Yes，+主语+提问的词. 否定：No，+主语+提问的词+not. Are you from Japan﹖ Yes ,I am． / No, I'm not． Is her sister doing her homework now﹖ Yes, she is． / No, she isn't． Does he work in a bank? Yes, he does． / No, he doe
2、sn't． Can you speak French﹖ Yes, I can． / No, I can't．一般疑问句还有下列特点： 1、以be动词、助动词或情态动词开头；Is your father a teacher? Does Catherine like animals? Can Jenny speak French? 如何将陈述句变成一般疑问句？ 1.如句中有be 动词（am、is、 are、 was、 were）情态动词（can、may、must …）或助动词（do、does、did、 have、 had（完成时中））时，可直接将它们提到句首，句末打上问号即可
3、。主语为第一人称，应将其改为第二人称。例： It was rainy yesterday. →Was it rainy yesterday? Tom's father can play the piano. Can Tom's father play the piano? I have finished my homework. →Have you finished your homework? 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
4、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形。例：They go to school by bike. Do they go to school by bike? Bill gets up at 6:30 every day. Does bill get up at 6:30 every day? The students saw a film yesterday. →Did the students see a film yesterday?三.陈述句
5、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人称，则变问句时最好要变为第二人称。 I usually have lunch at school. Do you usually have lunch at school? 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.
6、 Is there any water on the playground? 3.复合句变一般疑问句通常只变主句，从句不变。 I know he comes from Canada. Do you know he comes from Canada? 4．如果句中含有实义动词have且表示“有”时,除借do外，也可将其直接提到句首。 例：I have some friends in America. Do you have any friends in America? 肯定句改否定句的方法—1、 在be动词后加not。如：is not
7、， are not ， am not， was not， were not； 2、 在can，should， will等后加not。如：cannot， should not， will not； 3、上述都没有的，在动词前加助动词否定形式don’t/doesn’t/didn’t。 4、 some 改成any。 把下面的句子变成否定句。 1.She is watching TV now. 2.We go to
