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
3、 day? 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
4、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? 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 Am
5、erica?/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 fathe
6、r 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. 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 mustn
7、t. (2)用 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。
