把肯定句改为否定句练习题
肯定句改双重否定句的方法及练习含答案
肯定句改双重否定句的方法及练习含答案双重否定句是指在一句话中使用两个否定词语，表示肯定的意思，但必须有否定的意义在其中。
这种句子的作用是加强语气。
例如，“他不是不来”意思是他要来的。
常用的双重否定词包括不得不、不能不、难道……不……不可能不、不会不、怎么会……不、不是不等。
双重否定句可以通过三种形式表达。
第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。
例如，“我不能不被他感动得流下泪来。
”第二种是一个否定副词加上一个否定意义的动词，例如“我们不能否认老一辈人的功劳。
”第三种是一个否定副词（或否定意义的动词）加上反问语气，例如“他感人的事迹，叫我怎么不流泪呢？”要将肯定句改为双重否定句，可以使用表示判断的“是”“了”用“谁也不能否认”，表示非常肯定的“一定”“必须”用“非……不可”“不能不”，表示不情愿、不得已的“只能”“只好”“只得”用“不得不”。
双重否定句的作用是加强语气，具有强调肯定意义的效果。
使用双重否定句时，需要注意不要过度使用，以免造成歧义。
删除明显有问题的段落后，改写如下：双重否定句是使用两个否定词来表达肯定含义的句子，如“不……不”、“没有……不”、“非……不”等。
双重否定句的语气比一般肯定句强烈或委婉。
例如，“他不敢不去”、“我不得不告诉你事情的原委”、“没有谁不惧怕他的威严”、“你若是想在这个世界留下值得人怀念的事迹，那就非得有毅力不可”、“他不会不同情我的”、“没有什么不可以”。
书面语中还经常使用“无不”、“无非”、“不无”、“未必不”等双重否定词语来表示肯定。
练：我对老师们的勇敢，从心底里感到无限的敬佩。
可以改为“我对老师们的勇敢，不可能不从心底里感到无限的敬佩”。
双重否定句有两种形式：由两个“不”构成或由一个反问词（如“难道”、“怎能等”）加一个“不”构成反问句，但也是双重否定句。
双重否定句表示肯定的意思，语气比陈述句强烈。
改写为双重否定句的方法是在谓语动词前加双重否定词，如“没有……不”、“……无不……”、“非……不……”、“……不曾不……”、“……不能不……”、“……不会不……”等。

肯定句改双重否定句40句例子
肯定句改双重否定句40句例子篇一小学语文课本里有很多肯定句，把它们改成双重否定句能让句子的语气更加强烈呢。
比如“他是一个好学生。
”改成“他不能不是一个好学生。
”这里用了“不能不”，强调了他肯定是好学生的程度更高啦。
为啥这样改呢？因为双重否定其实表达的是肯定的意思，但语气更强烈。
就像这句话，本来只是说他是好学生，改完后让人感觉他绝对是好学生，没有任何疑问。
再看“她很漂亮。
”可以改成“她不能不漂亮。
”或者“她不是不漂亮。
”这样改完后，更加突出了她的美丽程度。
用“不能不”强调了必须漂亮，“不是不”则是一种委婉的双重否定，也表达了她漂亮这个事实。
“小明很勇敢。
”改成“小明不能不勇敢。
”这句话强调了小明的勇敢是毋庸置疑的。
用双重否定让人们更加深刻地感受到小明的勇敢品质。
“我喜欢看书。
”可以改成“我不能不喜欢看书。
”或者“我非喜欢看书不可。
”“不能不”直接强调了喜欢看书的必然性，“非……不可”则表达了一种强烈的愿望，就是一定要喜欢看书。
“老师很负责。
”改成“老师不能不负责。
”这句话突出了老师的责任感。
双重否定让人们更加相信老师的负责态度。
“这朵花很美丽。
”改成“这朵花不能不美丽。
”或者“这朵花不是不美丽。
”再次强调了花的美丽程度。
“他学习很努力。
”改成“他不能不学习努力。
