肯定句改双重否定句的方法和练习含答案
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
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） 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 否定句 疑问句之变形技巧
肯定句/否定句/疑问句之变形技巧 一、肯定句改否定句 1、be动词后加not，诸如：is not(isn't)，are not(aren't)，was not(wasn't)，were not(weren't)，am not（无缩写）。 ◆He is a student. 他是一个学生。--- He is not a student. 他不是一个学生。 ◆They were watching TV then. 那时他们正在看电视。--- They weren't watching TV then. 那时他们没在看电视。 2、情态动词等后加not，诸如：can not(can't)，will not(won't)，should not(shouldn't)，must not(mustn't)，need(needn't)等。 ◆She can take care of herself. 她能照顾好她自己。--- She can not(can't) take care of herself. 她不能照顾好她自己。 ◆You should go home. 你应该回家。--- You shouldn't go home. 你不应该回家。 3、若无法找到be动词或情态动词，就在已有动词前额外加助动词否定形式：don't/doesn't/didn't，同时将动词变原形。 ◆She likes the room. 她喜欢这房间。--- She doesn't like the room. 她不喜欢这房间。 ◆We did our homework yesterday. 我们昨天做了作业。--- We didn't do our homework yesterday. 我们昨天没有做作业。 注：句中若有some ，须将其改成any。

肯定句改双重否定句的方法详解及练习、答案
肯定句改双重否定句的方法及练习答案肯定句与否定句的变换包括换为单重否定句和双重否定句，句式互换后意思不会改变，但语意轻重上会发生一些变化。从语意轻重上说，单重否定句最轻，肯定句较重，双重否定句最重。下面我们具体谈谈肯定句怎样变换为否定句。一、肯定句变为单重否定句方法：是先找出谓语的反义词，然后再否定这个反义词。示例：经过努力．这些问题是容易解决的。（肯定句）经过努力，这些问题是不难解决的。（否定句）二、肯定句变为双重否定句 1.方法：双重否定句就是表示肯定的意思，语气比陈述句强烈．那么改写就是在谓语动词前加双重否定词就可以了． 2.常用的双重否定词：没有…不；…无不…；非…不…；…不曾不…；…不能不…；…不会不…等。3.双重否定词替换方法：①表示判断。“是”“了”用“谁也不能否认” ②表示非常肯定。“一定”“必须”用“非不 可”“不能不”③表示不情愿、不得已。“只能”“只好”“只得”用“不得不”④表示全部。“全”“全都”“全部”用“没有不”“无不”⑤表示推测。“会”“可能”“能”“应该”用“不可能不”“不会不” 4.示例：他今天一定来。（肯定句）他今天不能不来。（双重否定句）我必须工作。（肯定句）我不得不工作。（双重否定句）病人需要去医院。（肯定句）病人不能不去医院。（双重否定句）订购商品到货后才付款。（肯定句）订购商品不到货不付款。（双重否定句）5.把肯定句改为多重否定句，表示否定的意思时，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。 6.注意：由肯定句变成双重否定句或否定的反问句时．千万不要把意思说反了。须知：双重否定表示肯定，三重否定还是表示否定（单数否定还是表否定）。下列三句是把意思说反了的例子。 a．科学发展到今天，谁也不会否认地球不是围绕太阳转这个简单的事实． b．老一辈革命家无时无刻都在关心青年一代的成长。c．难道能否认《红楼梦》不是一部很好的古典小说吗分析： a出现三重否定。由于“否认”的宾语是一个复指短语，本例只能去掉第三重否定“不是”。 b无时无刻”是把“无”字嵌进“时刻”一词，只能算一重否定，应把“都”改成“不”，才能构成双重否定。 c已有两重否定更多肯定句否定句句式转换资料，再加上反问又等于一重否定，便构成三重否定，可去掉“不”字。 7.专题练习：把下列句子改为双重否定句 1、万里长城是世界历史上的一个伟大奇迹。 2、写得不怎么样，但还是有希望的。 3、问题还没有弄清，但已经有了一点儿头绪.4、他这样做虽然过分了点，但还是有道理的. 5、你承认电子计算机是“天之骄子”。 6、燕子飞过大海，肯定非常辛苦、艰难。 7、爹妈都不在家，只好自己动手丰衣足食了。 8、在共产党面前，什么困难都能克服。 9、这部电影使我感动得流泪。 10、黑熊躲进大树洞里。 11、下个星期天，妈妈要带我去西湖划船。 12、星期天,我们必须去看排球赛。 13、学校里只给每人发一张票,这真叫人为难。 14、红四团的战士必须抢在敌人前面赶到泸定桥。 15、这件事是事实。 16、我是好学生。 17、人都喝水 8.参考答案 1)万里长城不能不说是历史上的一个伟大奇迹2、写得不怎么样，但不是没有希望的。 3、问题还没有弄清，但不是没有一点儿头绪.4、他这样做虽然过分了点，但不是没有道理的.5、你不得不承认电子计算机是“天之骄子”。6、燕子飞过大海，不可能不辛苦、艰难。 7、爹妈都不在家，不得不自己动手丰衣足食了。8、在共产党面前，没有困难不能克服。9、这部电影不能不使我感动得流泪。10、黑熊不得不躲进大树洞里 11、下个星期天，妈妈不得不带我去西湖划船。12、星期天,我们不得不去看排球赛。 13、学校里只给每人发一张票,这不能不叫人为难。14、红四团的战士不得不抢在敌人前面赶到泸定桥。 15、这件事不可能不是事实。16、我不可能不是好学生17、人不可能不喝水。
