英语句型转换(⼀般⼀问句转特殊疑问句)
★必备知识点:
1.be动词:am、is、 are、 was、 were;⼩学阶段,be动词后只接名词,形容词或动词的
ing形式。
2.助动词:do、does、did、 have、 had;助动词后的动词⽤原形。
3.情态动词can、must、will、may、need等;情态动词+动词原形
⼀、肯定句、否定句定义
1.肯定句:表⽰肯定的意思, 即不含有否定词“不”。
例:我是⼀个学⽣ I am a student. 他去上学 He goes to school.
2.否定句:表⽰否定的意思。
例:我不是⼀个男孩。 I am not a boy 他不去上学 He does not go to school.
⼆、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 Catherine like animals
Can Jenny speak French
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:你⽗亲是⽼师吗凯瑟琳喜欢动
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(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
Tom's fa ther 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 a t 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 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/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)的确定可以概括例下:1.第⼀个词:不是Yes就是No。(注意: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 Anna′s father a doctor No,he isn′t.
如果主语是 this that,回答时⽤ it 代替,如果问句中主语是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。
例:Can Jim play soccer Yes, he can.
Does Mr Bean speak English Yes, he does.
需要注意问题:
⽤ may 引导的问句,肯定回答⽤may,否定回答⽤can′t 或mustn′t,
⽤ must 引导的问句,肯定回答⽤ must,否定回答⽤needn′t.
例:May I go to the park now Yes, you may. /No, y ou mustn′t.
Must I wash my clothes now Yes, you must. /No, you needn′t.
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 didn′t.
三、特殊疑问句
(⼀)什么是特殊疑问句:以疑问词开头,对句中某⼀成分提问的句⼦叫特殊疑问句。★(⼆)常⽤的疑问词有:
★(三)⼩学阶段,特殊疑问句句型结构有:
1、特殊疑问词+助动词+主语+动词原形+其他
eg:Where do you do study English
2、特殊疑问词+be动词+主语+其他
eg:Why is your Mum so angry
3、特殊疑问词+情态动词+主语+动词原形+其他 eg:What can I do for you
★(四)肯定句、否定句、⼀般疑问句和特殊疑问句的相互转换
1、肯定句变否定句:在am, is, are 后⾯加上not,其余按顺序照抄。
