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

your
mother.
she
isn't
your

2.如果没有be动词或情态动词,加don't,does't或did't
she
likes

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,

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did
she
likes
playing
football.
Does

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

② 【英语语法】并列句里的肯定和否定式
He likes singing, enjoys drawing and does sports a lot, but doesn't watch TV very often.
He likes to sing on Tuesdays, and on sunny Wednesdays, he draws. But he doesn't watch TV very much.
but 连接的句子也是并列关系。但是转折的意思。
供参考,祝进步!
③ 英语关于部分否定与全部否定的语法区别
简单地总结一下哈:
【第一种情况】英语中那些表示全部或所有的词,只有在肯定句中,才能表达出真正的“全部”或“所有”之意。如:all, everyone, both(容易忽略)等。相反,它们在 not 否定句中,却表示部份否定,如:“不全…”或“不都…”。
【第二种情况】由于使用了 and 连接两个关列的词语,在 not 否定句中也会造成句子出现部分否定;而使用or就不会否定一部分,而是全部否定。在肯定句中就不存在此问题了哈。
【第三种情况】由于第二种情况的存在,所以,与 and 有相同作用的词 as well as 也存在同样问题,即在否定句不是全盘否定,而是部份否定。
特别说明:在使用 and 和 as well as 表达部份否定时,要注意被否定的部份刚好相反,这是因为两者的强调对象刚好相反(有人认为 and 在连接对象上没有强调一说,估且认为放在后面说的就是重点好了,不过强调之意不太强烈,绝非not onle …but also中的味道罢了)。如:not A and B 否定的是 B,而 not A as well as B 则否定的是 A。即被否定的正是被强调对象。
【第四种情况】就是否定词本身的事了哈。即 not 和 no 在部份否定中的用法,前面已经说过 not 与 or 在句中不会形成部份否定,所以就只有 no 和 or 的搭配了哈。即:not A or B = no A or no B。假如少了一个 no,句了就变成部份否定了哈。这与 not 和 no 在否定含义上的差别有关。
最后补充一点,在第一种情形下,not 放在 all, every, both 等词前面较容易理解,但是一定要注意,如果句子中不是这种结构,其用意是相同的,千万不要理解或翻译错了哈。
④ 英语语法中否定句分为哪几种他们的定义是什么
去买本乐事英语-
初中语法专练。
词定义很多,现在很多人应该都没时间。
⑤ 英语中肯定句怎么变否定句
你好,要想学好英语,你要不断积累,这样你就可以将英语学好。我帮你总结几点,供你参考,谢谢。
一、当肯定句的谓语动词是be或由be构成时,改为否定句,应在be后面加not。二、当肯定句的谓语动词只是行为动词时,改为否定句,要用“助动词do(does,did)+not+动词原形”。三、当肯定句的谓语是由“情态动词can,may,must等+动词原形”构成或由“助动词will,have,had等+动词原形(或动词的现在分词、过去分词)”构成,变否定句,要用“情态动词/助动词+not+动词原形(或动词的现在分词、过去分词)”构成。四、当肯定句的谓语是have时,分两种情况:1.当have作“有”讲时,变否定句的方法有:a.由have
+not
+其它;b.由have
+no
+其它;c.由
don't(doesn't,didn't)+have+其它。2当have既不当作“有”讲,也不是助动词,而是行为动词时,改为否定句,要用“助动词do,
does,did等+not
+have”构成。五、当肯定句中含有情态动词have(has)to时,改为否定句,有两种构成法,一种借助do,一种不借助do(仅限于现在时和过去一般时),多数人用第一种形式。六、当肯定句中含有too,also时,改为否定句,须将too,
also改为either。七、当肯定句中含有always时,改为否定句,须将always改为never。八、当肯定句中含有already时,改为否定句,须将already改为
yet。九、当肯定句中含有nearly时,改为否定句,须将nearly改为
hardly。

⑦ 英语句子改为肯定句与否定句怎么改
肯定句变否定句加NOT或是像Never类似的否定词啊。建议你买本语法书看看吧
⑧ 英语肯定句否定句用法
肯定句 I+do\am+其它 He+does\is+其它 You+do\are+其它
否定句 I+do\am+not+其它 He+does\is+not+其它 You+do\are+not+其它
应该就是这样,希望能帮助你
⑨ 英文写作如何使用否定语法
英语否定语法包括两种。
一. 部分否定句。
例:Both Lily and Lucy are students.Lily和lucy都是学生。
Both Lily and Lucy are not students. Lily和Lucy并不全是学生,指一个是,一个不是
除了both外,这些词还包括all,everyone,anyone,someone,something,anything,everything.肯定句的时候是全盘肯定,否定句的时候是部分否定
二.全部否定句。
例:They will ask Lucy and Lily to come to the party.
They will not ask Lucy or Lily to come to the part.表示他们既不会叫Lucy也不会叫Lily参加晚会。
Neither Lucy nor Lily will attend the part.也是全盘否定
总结:表达这类词首先要弄清楚想要表达,需要否分否定就用部分否定,需要全部否定就全部否定。
另外还有一种是否定,但要注意表达。
例:我认为小鸭不会游泳的表达
正确:I do not think a ck can swim
错误:I think a ck cannot swim.
看上去差别不大,但英语中就是这么表达的,此类词还包括:wish,believe,hope等
