初中英语句型转换
一、肯定句改的方法——一步法
1. 有be动词(is are am were was)/情态动词(can，could, will, would, shall, should，must，may)的。在be动词/情态动词后后加not。
2. 无be动词/情态动词，一般现在时在动词前加don’t第三人称单数前doesn't/一般过去式 didn’t。
3加doesn't/ did n’t的句子注意，句子动词要变成原型。
二、肯定句改一般疑问句的方法——三步法
1. 有be动词/情态动词：be动词/情态动词提到句首，其余照抄，(some改成any，第一人称变为第二人称my改成your , I 改成you,we 改成you,our改成your ）句末用问号。
2. 无be动词/情态动词，在句首加Do/Does/Did，其余照抄，(some改成any，第一人称变为第二人称my改成your , I 改成you,we 改成you,our改成your ）句末用问号。
3. 加Does、did的句子注意，句子动词要变成原型。
例如 陈述句: They are in the park. He can play the guitar. He likes the dogs.
否定句They are not in the park. He can not play the guitar. He doesn't like the dogs
一般疑问句: Are they in the park? Can he play the guitar? Does he like the dogs?

B：once a month. 每月一次。
3、how soon指再过多久，主要用来对表示将来的一段时间(如：in an hour, in two weeks 等)提问。如：

B：My house is three miles from school. 我家里学校有三英里
对画线部分提问，除了要注意选择正确的疑问词外，还要注意语序的运用。
1、 对句子的主语提问，其语序是：疑问词+谓语+其他成分？（整个句子是陈述句语序）
She is their teacher. Who is their teacher?
主语 谓语 主语 谓语
2、对句子主语的定语部分提问，其语序是：
疑问词+主语（即定语所修饰的名词）+谓语+其他成分？（整个句子是陈述句语序）
My book is over there. Whose book is over there ?
主语的定语主语谓语疑问词主语谓语
以上两点方法都是：
用正确的疑问词代替画线部分，再把句号改为问号，其余部分一般不做改变
3．对表语或宾语的定语部分提问，其语序是：
疑问词+表语或宾语（画线部分所修饰的名词）+一般疑问句（省略画线部分和它所修饰的名词）

宾语的定语 宾语 疑问词宾语一般疑问句(省略掉my watch)
4、对表语、宾语或状语提问，其语序是：疑问词+一般疑问句（省略掉画线部分）？

状语疑问词一般疑问句（省略掉画线部分in Beijing ）
5、对谓语和宾语提问，其语序是：
疑问词(What)+一般疑问句（其中谓语动词要用do的相对应形式代替, 省略掉宾语)
