小学英语句型转换专项练习.

句型转换方法归纳一、改为否定句1、先找be动词或情态动词.如果有这些词，直接在这些词的后面加not， some 改成any，其余照抄；2、如果句子中没有be动词或者是情态动词，要在动词前面加don’t 、doesn’t或者是didn’t，some 改成any，其余部分照抄。

(1)首先判断句子时态，如果句子是过去时，则要在动词前面加didn’t，这个动词用原形；(2)如果句子不是过去时，则判断主语是否为第三人称单数，如是，要在动词前面前加doesn’t，这个动词改为原形，其他情况均要在句子动词前面加don’t。

二、改为一般疑问句（some 改成any，I改成you，my改成your，句号改成问号，其余照抄）1、先找be动词 am, is, are, was, were或情态动词can, should等等 .如果有这些词，直接把这些词放在句子最前面，；2、如果句子中没有be动词或者是情态动词，要在句子最前面加助动词 do 、does或者是did，后面动词用原形。

(1)首先判断句子时态，如果句子是过去时，则要在句子最前面加Did；(2)如果句子不是过去时，则判断主语是否为第三人称单数，如是，要在句子最前面加Does, 其他情况均要在句子最前面加Do三、对划线部分提问第一步：先把句子改成一般疑问句第二步：把提问部分省略，在句子最前面加疑问词。

（如果提问部分是动词词组，要把它改成do；如果提问部分是动名词词组，要把它改成doing）（注：如划线部分为主语，则用who代替，其余照抄）一,对下列句子中划线部分提问1,The deepest part（最深的部分）of the water is near Japan.______________________________________________________________ 2,My father will take me to Beijing.______________________________________________________________ 3,My trip to Xi’an is great.______________________________________________________________ 4,Harry Potter Ⅳ will be on this afternoon.______________________________________________________________ 5,I’m looking for a dress.______________________________________________________________ 7,I saw many animals in Beijing Zoo.______________________________________________________________ 8,I often help my grandfather on the farm.______________________________________________________________ 9,I am from Australia.______________________________________________________________ 10,We will go to the nearest supermarket.______________________________________________________________ 11,My new pencil-box is about ten yuan.______________________________________________________________ 12,The name of the book is Sleeping Beauty.______________________________________________________________ 13,He came to visit China two days ago.______________________________________________________________ 14,There are twelve students over there.______________________________________________________________ 16,These sneakers are 280 yuan.______________________________________________________________ 17,I get up at 6 o’clock every morning.______________________________________________________________20,Tom saw many places of interest（名胜古迹）in that old city.______________________________________________________________ 21,I came here by train.______________________________________________________________ 22,We are going to buy tomorrow’s air tickets.______________________________________________________________ 23,He’s making a model ship.______________________________________________________________ 24,My father works in Africa.______________________________________________________________ 25,Mike wants to be a singer(歌手) in the future.______________________________________________________二,把下列句子变为一般疑问句:1.
