陈述句改成双重否定句的方法和步骤
陈述句改成双重否定句的方法和步骤： 1、根据句子意思，选择恰当的双重否定词； 2、替换或删去原句中“要、得(děi)、都、应该、只好、一定、必须、肯定”等词语； 3、删去原句中“很、非常、十分、分外、更加”等表示程度深的词语； 4、检查改后的句子是否读得通顺。 双重否定词及分类： 1、不得不、不能不、不会不、不是不、不敢不； 2、无不、无非、没有不、不是没有、不可能不； 3、不……不……、没有……不……、非……不可。 双重否定是一句话中有两个否定词语，加强了肯定的意思。双重否定句的作用是加强语气。分类 双重否定句主要有三种形式。一种是两个否定副词连用，一种是一个否定副词加上一个否定意义的动词，再一种是一个否定副词（或否定意义的动词）加上反问语气。这三种句式中，否定副词（或否定意义的动词）加反问语气的，都具有加强语气的作用。例如，“敢于这样做的人，难道不是一个英雄吗？”，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”。 双重否定有两种形式： 1、由两个不构成。如：这件事我不得不做。 2、由一个反问词(难道，怎能等)加一个不组成，构成反问句．但也是双重否定句． 双重否定句就是表示肯定的意思，语气比陈述句强烈． 1、香港回归伟大的祖国，我们不得不感到无比自豪。 2、您为我们付出了这样高的代价，不得不表达您对中国人民的友谊。 3、没有哪个小孩子不喜欢小动物。 4、我对同学们的勇敢精神，从心底里不得不感到无限的敬佩。 5、信赖，不得不创造出美好的世界。 6、这不会不是伟大的奇观。 7、你不得不知道这件事。 8、我们不得不建成了希望小学。 9、詹天佑不会不是我国杰出的爱国工程师。 10、星期天,我们非去看排球赛不可。 11、报纸的诱惑力如此之大，每日非要读它不可。 12、他这样做虽然过分了点，但并不是没有道理的。 13、写得不怎么样，不是没有希望的。 14.我不得不承认那个是我的东西. 15.幼儿园的小朋友没有一个不喜欢王老师。 16.你不会不知道这件事。 他不可能不那么高。 这些灯没有哪两盏是相同的。 他不可能不迟到。

如何把英语陈述句改成一般疑问句如何改否定句
一、含有be动词的一般疑问句,通常把be动词调到句首。例如: 陈述句:They are in the swimming pool. 一般疑问句:Are they in the swimming pool? 注意:一般疑问句句末要用“?”。 二、含有情态动词的一般疑问句(can, may...),把情态动词调到句首。例如: 陈述句:He can drive a car. 一般疑问句: Can he drive a car? 三、含有have的一般疑问句,have译为“有”。一般疑问句式有两种形式: 1.把have/has调到句首。例如: 陈述句:Tommy has a computer. 一般疑问句:Has Tommy/he a computer? 2.加助动词do/does,第三人称单数用does,其他人称用do。其句型为:Do/Does + 主语+ have...?例如上句可变为: Does Tommy have a computer?一般疑问句：以be动词, have /has/do等助动词、can/may等情态动词开头，以yes或no来回答的问句。 它的基本结构是：Be/Have /Has/Did等助动词（包括情态动词）＋主语＋谓语（包括表语）＋┄？回答常用简略回答。 四、句子里没有be动词、助动词、情态动词（am/is/are/was/were/will/can/may/must/could/have/has[有])等，就需要加助动词do, does,（三单）、did（过去式）来构成疑问句，加上这些助动词后，句子中谓语动词必须用原形。 其句型为:Do/Does/did + 主语+ 动词原形+其它? 陈述句:Amy speaks English. 一般疑问句:Does Amy speak English? 注意：在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词，如果有也必须进行改变，already要改成yet，some、something、somebody等分别改成any、anything、anybody等。另外，在改成否定句的时候注意把too改成either,both改成neither,all改成none等.在改成一般疑问句的时候，常常把第一人称I、we改成第二人称you。 好了,知道了如何问话之后,我们来了解一下如何回答一般疑问句。首先要有人称的改变。当主语为名词时,在答语中要改成其相应的代词。另外,答语有两种,肯定的回答(用yes)和否定的回答(用no),否定式常用缩写形式。现在还是让我们分句型一一说明。 一、一般疑问句含be动词时,用be动词回答,句末用句号。例如: -Is Mary your sister? -Yes, she is. / No, she isn’t.(缩写) 二、一般疑问句含有情态动词(can, may, should等)时,用情态动词回答。例如: -May I come in? -Yes, you may. / No, you can’t. 三、一般疑问句含有have(译为“有”)时,有两种回答方式。 1.直接用have/has回答。例如: -Have they any pictures? -Yes, they have. / No, they haven’t. 2.用助动词do/does回答。例如: -Does Millie smoke? -Yes, she does. / No, she doesn’t. 四、一般动词的一般疑问句回答时也用助动词。例如: -Do the workers live in London? -Yes, they do. / No, they don’t.
