15、nch at noon.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。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；例：Is your father a teacher? Does Jack like animals? Can Lucy speak English?2、往往读升调；3、译成汉语，都可以带上“吗” ，例如上面三句可分别译为：你父亲是老师吗？杰克喜欢动物吗？露丝会说英语吗？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
16、词（do、does、did、 have、 had）或情态动词（can、must、will、may 等） ，2) 有，直接将它们提至主语前，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 your homework?3) 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。
17、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 day?The students saw a film yesterday.Did the students see a film yesterday
18、?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 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 t
19、he 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?/Do you have any friends in America?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（三个单词）的确定可以
20、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 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
21、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，用 must 引导的问句，肯定回答用 must，否定回答用 neednt. 例：May I go to the park now? Yes, you may. /No, you mustnt.Must I wash my clothes now? Yes, you must. /No, you neednt.4用 No 开头作
22、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）.特殊疑问句以疑问词开头，对句中某一成分提问的句子叫特殊疑问句。常用的疑问词有：what who whose which when where how why 等。特殊疑问句有两种语序：如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈
23、述句的语序：疑问词（主语）谓语动词其他成分？如：who is singing in the room whose bike is broken如疑问词作其他成分，即对其他成分提问，其语序是：疑问词一般疑问句语序？ 如：what class are you inWhat does she look likeWhere are you fromWhat time does he get up every morningHow do you know特殊疑问词+助动词+主语+动词原形+其他？eg:Where do you do study English?特殊疑问词+be 动词+主语+其他？eg:W
24、hy is your Mum so angry?特殊疑问词+情态动词+主语+动词原形+其他？eg:What can I do for you?注意：回答特殊疑问句时，不能用 yes no，即问什么答什么，尤其是简略回答。如：Who is from Canada Helen (is)Wheres the restaurant Near the stationWhy do you like koalas Because they are cute一、把陈述句变为一般疑问句1.
