一般疑问句的改法：对含有be(am、is、are等)动词、情态动词（can、may、must、should等）和助动词（will、would等）的句子，应直接将这些be动词、情态动词和助动词提到句首。
口诀“一调、二改、三问号”就说明了一般疑问句的变法：一调就是将be动词、情态动词和助动词提到句首，二改就是将大小写进行变化；将some改为 any; 将你（you）、我(I)进行变换，三问号就是在末尾加一个问号。
如果一个句子中没有be动词、情态动词或助动词，则需要助动词来帮忙。
如果主语是第三人称单数（he、she、it或者是单数名词等），就在句首加does，同时后面的谓语动词要恢复原形;如果是其他人称则在句首加do.如：Jim is eighteen.-----I s Jim eighteen?Jim’s father can make a plane.-- C an Jim’s father make a plane?Jim’s children like dancing.-- Do Jim’s children like dancing?Tom gets up late. --- D oes Tom get up late?一般疑问句的答法：一般用Yes/No来回答，在Yes/No后面加上对应的人称代词的主格（I/you/he/she/it/we/you/they）和对应的be动词或情态动词或助动词（do/does）(一般就是一般疑问句的开头的那个be动词或情态动词或助动词)如：上面的四句肯定回答 Yes, he is.Yes, they can.Yes, they do. Yes, he does.否定句的改法：对含有be(am、is、are等)动词、情态动词（can、may、must、should等）和助动词（will、would等）的句子，应直接在这些词的后面加上not即可。
你还可以使用缩略形式，如 isn’t 、aren’t 、can’t、 won’t 等等。
如果一个句子中没有be动词、情态动词或助动词，则也需要助动词来帮忙。
如果主语是第三人称单数（he、she、it或者是单数名词等），就在主语后面加上doesn’t;如果是其他人称则用don’t. 如：将下面的句子改为一般疑问句并作肯定回答、否定回答后，再将他们改为否定句1. 含be动词的转换：1) She’s my mother.2) That’s a teacher.3) There’s a table in my room.4) There are some books in my bag.5) We are students.6) They’re polite and helpful.7) You’re from America.2. 含情态动词的转换：1) You can swim in the lake.2) We must do our homework first.3) ★ They must wait for the green light.4) She can park her bike in front of the supermarket.5) We should be at school by eight o’clock.6) Mary can bring her bag into the supermarket.8）I would like to play with you now.3. 既没有be动词也没有情态动词的转换：1）I have a computer.2) We have some model planes in our room.3) They’ve many books in their bags.4) You have some good friends.5) Lily has a goldfish in her room.6) Tom’s mother has a pair of glasses.7) I get up at 6:00 in the morning.8) He goes to school from Monday to Friday.9) Many students have pets in our class.10) She likes reading in the library.11) Miss Gao enjoys walking down the street.12) His parents usually stay at home at the weekend.13) Her mother exercises in the garden for about half an hour.14) Her father often goes home by bus.4. 混合转换（要求同上）：1) He has some friends.2) There are some animals in the zoo.3) His sister goes to school by bike.4) They like English very much.5) She usually takes a bus home.5. 特殊转换同义句（附加题）a) You’reJill,right?b) Thank you verymuch.c) What’s hisfather?d)She isEnglish.e)Tom has some books in hisbags.f) Andy sits on my right and Nick is on my left.g)I sit behindMillie.h)This is myWalkman.i)That computer ismine.j)Whose tennis rackets arethese?kYou can’t park your bike in front of the supermarket. l)Don’t eat snacks inclass.m)What time isit?n)Our classes begin ateight.o)She often helps Mum do the housework.p)Miss Gao doesn’t go home bybus.q)My brother rides a bike toschool.r)Nice to meetyou.s)Do you want to play withme?句型转换专题讲练（2）句型转换 (划线提问)一、转换口诀：“一选二加三去”一选就是选好疑问词，二加就是在疑问词后面加上一般疑问句，三去就是去掉划线的部分。
