1、一、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（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 was rainy yesterday. Was it rainy yesterday? Toms father can play the piano. Can Toms father play the piano? I have finished my homework. Have you finished

2、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 gets up at 6:30 every d

3、ay? The students saw a film yesterday. Did the students see a film yesterday? 二、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人称，则变问句时最好要变为第二人称。 例：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 so

4、me, 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? 3.复合句变一般疑问句通常只变主句，从句不变。 例：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. Have you any friends in America

5、?/Do you have any friends in America? 三.一般疑问句的回答 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（三个 单词）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, Certainly, Of course 等代替.NO 可由 sorry 代替.） 2.第二个词：问谁答谁。即答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 doct

6、or? 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. 需要注意问题： （1）用 may 引导的问句，肯定回答用 may，否定回答用 cant 或 mustnt， May I go to the park now? Yes, you may. /No, you mustnt. （2）用

7、must 引导的问句，肯定回答用 must，否定回答用 neednt. 例： Must I wash my clothes now? Yes, you must. /No, you neednt. 4用 No 开头作否定回答时,结尾要加上 not。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:Did Thomas come here yesterday? Yes, he did./ No ,he didnt. Is Lin Lin in Class 3? Yes, she is./No, she isnt.或（No, shes not）. 四、总结：将陈述句改成一般疑

8、问句的方法： 三步法 1、有 be 动词，则把 be 动词放在句首，剩下的照抄，（some 改成 any，I 改成 you，my 改成 your，）句点改成问号。 2、有情态动词，则把 can，shall， will 等放到句首，剩下的照抄，（some 改成 any，I 改成 you，my 改成 your，）句点改成问号。 3、没有 be 动词，也没有情态动词的，则将助动词 Do/Does/Did 放到在句首，谓语动 词变回原形，剩下的照抄，（some 改成 any，I 改成 you，my 改成 your，）句点改成问号。 The city was big then. 以前，这个城市很大。 疑问句 Was the city big then? Yes, it was. I was at home yesterday. 昨天，我在家。 疑问句 Were you at home yesterday? Yes, I was. The cat was fat then. 以前，这只猫很肥。 疑问句 Was the cat thin then? No, it wasnt. The boys were cute then. 以前，这些男孩很可爱。 疑问句 Were the boys naughty then? No, they werent.
