英语中如何将肯定句变成否定句？肯定句变成疑问句？ 见以下，很简单.一.肯定句变成否定句如果句中有be动词is，am，are 或情态动词must，can等，在其后面直接加not，she is your mother.she isn't your mother2.如果没有be动词或情态动词，加don't，does't或did'tshe likes playing football.she doesn't like playing football.二.肯定句变成疑问句变成一般疑问句如果有be或情态动词动词就把他们提前，she is your mother.Is she your mother？2.如果没有就在前面加do的某种形式，第三人称用does，过去时用didshe likes playing football.Does she like playing football？变成特殊疑问句，要具体分析，看是对什么进行提问，简单来说，1.对人提问用who，she is your sister.Who is your sister？2.对事物用what，The book is on the desk.what it is on the desk？3对时间用when，She will come back tomorrow.When she will come back？4.对频率用how often等等 I play football everyday.How often does you play footall？基本就这些了，
改肯定句的方法有哪些？ 一、肯定句改否定2113句1、be动词后加not，5261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4102一1653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。I want some books.我想要一些书。I don't want any books.我不想要任何书。。
