1.肯定句、否定句的转换2.双重否定句、陈述句的转换双重否定句：就是否定两次,即表示肯定的意思，但必须有否定的意义在里面。

（双重否定句的作用是加强语气。

）双重否定句与陈述句的转换：（类似于反问句）一、双重否定句双重否定就是否定两次,即表示肯定的意思，但必须有否定的意义在里面。

例如:“他不是不来”意思是他要来的。

包括有双重否定的句子就是双重否定句。

比如:（1）我不得不承认那个本是我的. 分析：“不得不”就是双重否定这句话的原意为：我承认那个本是我的。

（2）幼儿园的小朋友没有一个不喜欢王老师。

“没有一个…不”就是双重否定词这句话的原句为：幼儿园的小朋友都喜欢王老师。

（3）你不会不知道这件事。

分析：“不会不”就是双重否定词双重否定从字面上就知道，是一句话中有两个否定词语，表示肯定的意思。

双重否定句是相对于单纯否定句而言的，它用否定加否定的形式，表达肯定的语意。

一般的语法书普遍认为，双重否定句的作用是加强语气。

在双重否定句中，有那么几个可以用：不得不、不能不、难道……不…… 不可能不、不会不、怎么会…… 不、不是不等双重否定句主要有三种形式。

（1）、一种是两个否定副词连用，谓语前面加“不。

不”，也就是负负为正的原理。

可用“没有……不……”“不……不……”如“我不能不被他感动得流下泪来。

”又如：这种新产品质量好，价格也便宜。

改为：这种新产品质量不能说不好，价格也不能说不便宜。

（2）、一种是一个否定副词加上一个否定意义的动词，如“我们不能否认老一辈人的功劳。

”（3）、再一种是一个否定副词（或否定意义的动词）加上反问语气。

如“他感人的事迹，叫我怎么不流泪呢？”另外、把肯定句改为多重否定表否定，使否定成分的个数成奇数个即可例如：我们不得不承认太阳不是绕地球运行的。

这三种句式中，否定副词（或否定意义的动词）加反问语气的，都例如，“敢于这样做的人，难道不是一个英雄吗？”（《内蒙访古》），意思就是“是一个英雄”，但语气更强烈，强调了敢于这样做的人是一个“大大的英雄”。

肯定句变否定句一、动词后直接加not。

I am a teacher. ---->I am not a teacher.我是一个老师。

---->我不是老师。

原句中含有情态动词 (can, shall, will, may, should, would, might, had better 等) 。

---->李雷不会游泳。

He will go to the zoo if it rains tomorrow.---->He will not/won't go to the zoo if it rains tomorrow.如果明天下雨，他将去动物园。

I get up at six o'clock every day.---->I don't get up at six o'clock every day.我每天六点起床。

小学英语所有句型转换的方法在几年的英语教学中，我总结了一些英语句子教学的小窍门，现简单归纳如下：一、肯定句改否定句的方法：1、在be动词后加not。

如：is not ， are not ， am not， was not， were not；2、在can，should， will等后加not。

如：cannot， should not， will not；3、上述都没有的，在动词前加助动词否定形式don’t/doesn’t/didn’t。

4、 some 改成any。

如： I am a girl. → I am not a girl.You are a student. →You are not a student.→You aren’t a student.This is Tom’s bag, → This is not Tom’s bag.→ This isn’t Tom’s bag.答题方法是；否定词not在be后边。

二、肯定句改一般疑问句的方法：1、把be动词放在句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。

2、把can，shall， will等放到句首，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。

3、上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，（some 改成any，I改成you，my改成your，）句点改成问号。

注意：句首的第一个字母要大写，句尾标点应为“？”。

如：I am in Class 6. →Are you in Class 6?You are from Ame rica. →Are you from America?It is an orange. →Is it an orange?答题方法是：要想提问，be提前，句末“？”别忘了。

4、就一般疑问句回答一般疑问句有两种回答，即：肯定回答和否定回答。
