孩子学了几年英语，仍旧不会变换一些基本的英语句型，英语中的句型转换非常重要，可以表达出不同的语气和思想。下面是小编收集整理的一些英语句型转换方法，大家一起来看看吧!
Ⅰ.题型介绍
所谓“句型转换”就是先给一个完整的句子A，再根据括号内的要求(有时没有明确，须自己观察)，在第二个句子B的空白处填上适当的词来完成的句型转换。
Ⅱ.题型分类
从形式上看，有如下几种形式:①某一词或词组的转换;②词组与句子的转换;③同义句型的转换;④为纠正常犯语言错误而设计的题目。
从内容上看，此题型涉及的面较广，主要有:①句子功能方面的转换。包括陈述句(肯定与否定)、四种题疑问句、祈使句、感叹句的转换;②句子结构方面的转换。即简单句、复合句、并列句之间的转换;③语态的转换。即主动语态与被动语态之间的转换;④常用句型与词汇手段的转换。
Ⅲ.具体分类如下
一、陈述句与疑问句、祈使句、感叹句间的转换
1、陈述句中肯定句变为否定句，大部分是用not来改变谓语结构，但也有借用否定意义的词，如nothing, nobody, none, neither, little, few, never, hardly等，例如::
A:Tom does well in maths.
B:Tom doesn't do in maths.
A:He has much to do.
B:He has nothing to do.
A:All of my classmates like art.
B:None of my classmates likes art.
2、改为疑问句。根据上下句的结构和词的减少，来判断变为哪一种形式的疑问句。例如:
A:My brother often has breakfast at school.
B: Does your brother often have breakfast atschool?
A:Tom's already weak in English.
B:Tom's already weak in English, isn't he ?
A:The red light changes every two minutes.
B:How often does the red light change?
3、改为感叹句。根据所给的句子结构和单词的词性，来确定使用哪一种感叹句的形式，例如:
A:This is an interesting book.
B:What an interesting book this is!
或 How interesting this book is!
二、同义句转换。
根据上句，写出一个意思相同(或相近)的下句，此类形式繁多，内容复杂，涉及面广，归类如下:
1、同义词或词组之间的转换。(通常上下句时态保持一致)。
常见的同义词或词组有:(1)四个“花费”(spend-take-cost-take);(2)三个“到达”(get to-reach-arrive in/at);(3)四个“收到…来信”(hearfrom-get a letter from-receive a letter from-have a letter from);(4)两个“擅长于…”(be good at -do well in);(5)两个“有空”(befree-have time);(6)三个“入睡”(go to sleep-get to sleep-fallasleep);(7)两个“玩得开心”(enjoy oneself-have a good time);(8)“给…打电话”(call sb-telephone sb-ring sb. a call-make a telephone to sb.)(9)“飞往…”(fly to…-go to…byair/plane)(10)“自学”(teach oneself-learn…by oneself)(11)在…方面帮助help…with…-help… (to)do…(12)在…差be weak in…-dobadly in…(13)能/会…can-be able to(14)更喜欢…like…better than…-prefer…to…(15)充满了…be full of…-befilled with…(16)放弃干…give updoing…-stop doing…(17)不再… no longer-not …any longer(18)照顾/保管 take care of…-lookafter(19)展览 on show-on display(20)阻止…干…stop…from doing-keep/prevent…from doing…(21)由于thanks to-because of…(22)举手handsup-put up one's hands(23)最后，终于at last-in the end(24)与…不同 be different from…-be not the same as…(25)从…借入… borrow…from…-lend…to…(26)乘公汽/火车/的士 go to…by bus/train/taxi-take a bus /train/taxi to…(27)乘自行车去… go to…by bike-ride a bike to…(28)为…感到自豪 be proud of…-be the pride of…(29)步行去… walk to…-go to…onfoot (30)独自地by oneself -alone等。例如:
A:The children had a good time in the park.
B:The children enjoyed themselves in thepark.
2、同义句型之间的转化。常见的同义句型有①It seems that 从句→Somebody seems(to be)+adj/n ②It's kind ofsb. to do…→Somebody is kind to do… ③What does…mean?→Whatdo you mean by…? 或What's themeaning of…?④There is somethingwrong with…→Something is wrong with… ⑤not…until…与when/after/before引导的时间状语从句的转换⑥What's wrong with…?→What's the matter with…? ⑦How is…?→What's…like…?⑧How do youlike…?→What do you think of?⑧It's time that…→It's time for sb. to do…⑨It's said that…→People say that…⑩Can I help you? →What can I do for you?
例如:
A:I went to bed after I finished myhomework.
B:I didn't go to bed until I finished myhomework.
3、if引导的条件状语从句的转化。例如:
A:If it doesn't rain tomorrow, they'll go tothe park.
B:Unless it rains tomorrow, they'll go tothe park.
A:If you don't hurry, you'll be late.
B:Hurry up, or you'll be late.
A:Fish can't live if there is no water.
B:Fish can't live without water.

2英语中句型转换的解题技巧
陈述句变一般疑问句
含有be动词的陈述句，通常把be提到句首，将第一人称变为第二人称，其余不变。
例:They are in the swimming pool.——Are they in the swimming pool?
I am making supper.——Are you making supper?
在陈述句中没有be，就要借助助动词do/does/did，将动词还原，第一人称变为第二人称，构成“Do/Does/Did+主语+动词原形+其他?”句型
例: I think maths difficult.——Do you think maths difficult?
Amy speaks English.——Does Amy speak English?
I paid two yuan for the pen.——Did you pay two yuan for the pen?
含有情态动词的陈述句，把情态动词提到句首，第一人称变为第二人称，其余不变。
例:He can drive a car.—— Can he drive a car?
含有have/has/had的陈述句，变疑问有两种形式:a.把have/has/had提到句首，第一人称变为第二人称，其余不变;b.加助动词do/does/did，第一人称变为第二人称，构成“Do/Does/Did+主语+have+其他?”句型。
例:Tom has a book.——Has Tom a book?
Tom has a book.——Does Tom have a book?
对特定(斜体、下划线、加粗)部分提问
根据特定部分的内容找出合适的疑问词(who, whom,whose,which,when等)。
将疑问词做主语放在句首，第一人称变为第二人称，其余部分变为一般疑问句跟在后面，特定部分不再出现。
例:I arrived at 7:00.——When did you arrive?
3英语中的陈述句如何改写成一般疑问句
具体规则如下:
1 总结起来很简单，就是be动词的句型，be动词一律提前到句首。
2 带有情态动词can, may, must 和need的句子，情态动词提前即可。同样，带有表示将来时态的shall或will的句子，shall或will提前即可。
3 行为动词do类的句子，用助动词do来帮忙，将do提前，后面用动词原形。(比较复杂点的就是第三人称单数，需要用does做助动词。)
现在分别举例说明:
1 He is a teacher. -------Is he a teacher?
观察:这两个句子的不同之处有:句末的标点符号不同了。he和is的位置不同了。需要注意的就是首字母的大写。这是很多同学开始学习时容易忽略的。
Be动词的变化形式有:am, is, are; was, were
下面大家可以去每个形式都去找一个句子，作为例句记录下来，加深印象。
2 He can do it well--------Can he do it well?
观察:这两个句子的不同之处有:句末的标点符号不同了。he和can的位置不同了。
当然这些情态动词还会有时态的变化，只要属于情态动词，就可以这样变化。
自己可以找一些例句，印证一下对不对。
3 He does his homework at home every day. -----Does he do his homework at home every day?
这里需要注意的就是疑问句中的do和does，第一个句子中的does是实意动词，第二个句子中的does是助动词，实意动词是do。大家一定要深刻领会这个规律。
I go shopping every Sunday.--------Do you go shooping every Sunday?
这里的do就是做go的助动词。
4英语句型转换公式
陈述句变为一般疑问句:直接把句子中的 be 动词提前,人称变换为相应的人称,后面加问号.
如果是动词的话,把动词去掉,句首加Do 的相应形式,后面加问号.
I am a you a boy?
I study in Beijing?Do you study in Beijing?
陈述句变为特殊疑问句
特殊疑问句是对时间发生的时间、地点、人物等的部分进行提问.需要用特殊疑问词来提问,原来句子中把答案部分省去,人称变为相应的人称,后面加问号.
I work in a do you work?
My mom is cooking is your mom doing?(对“cooking”提问)
或者 Who is cooking now?(对“mom”提问)
