五年级小学英语所有句型转换的方法基本助动词只有三个：be, do, have, 他们没有词汇意义，只有语法作用，如协助构成实行体，完成体，被动态，否定句，疑问句等。
陈述句也称为肯定句。
如，I like noodles .I am a child .I can have a pet .一、含有be 肯定句。
（我I用am, 你you 用are，is 跟着他he她she它it , 单数用is，复数用are。
）1，I am a child.2, You are a doctor .3, She / He is a nurse4 It is a book .5, There is a tree. There are many flowers .改否定句的方法——一步法在be动词后加not。
如：is not=is n’t ，are not=aren’t，am not，was not=wasn’t，were not=weren’t；1,I am not a child2,You are not a doctor.3,She / He isn’t a nurse...5, there isn’t a tree . there aren’t any flowers .改为一般疑问句肯定句改一般疑问句的方法——三步法把be动词放在句首，剩下的照抄，（some many 改成any，遇到第一人称改为第二人称例如I改为you , my改成your 等）句点改成问号。
1, Are you a child ? 做肯定或者否定回答：Yes , I am .No ,I’m not .2, Are you a doctor ？做肯定或者否定回答：Yes , I am .No ,I’m not .3, Is she /he a nurse ? 做肯定或者否定回答：Yes , she/he is .No ,she/he isn’t . 4,…5, Is there a tree ？做肯定或者否定回答：Yes , there is. No ,there isn’t . .Are there any flowers ?做肯定或者否定回答：Yes , there there are . No ,there aren’t . .二、含有can，should，would的句子，用法跟含有be 的句子相似。
肯定句：can，should，would 后面用动词原形1，I can sing and dance .2, she can draw .3，I would like a humburger .改为否定句：在can，should，would 等后加not。
如：cannot，should not，would not；1, I can’t sing and dance .2，She can’t draw.3,I wouldn’t like a humburger .改为疑问句：把can，shall，would等放到句首，剩下的照抄，（some many 改成any，遇到第一人称改为第二人称例如I改为you , my改成your等）句点改成问号。
）句点改成问号。
1,can you sing and dance ？做肯定或者否定回答：Yes , I can. No ,I can’t ..2,can she draw ?做肯定或者否定回答：Yes , she can. No ,she can’t.3,would you like a humburger ?做肯定或者否定回答Yes , I’d like . No, I wouldn’t like .三，不含有be 和can 的句子。
陈述句要注意动词有三单变化，如：1, I like noodles .2, She likes dumplings .3, He has a maker .改为否定句，在动词前加助动词否定形式动词原形前加don’t / 三单动词前用doesn’t，三单动词还原。
some 改成any。
1 ，I don’t like noodles .2, she doesn’t like dumplings.3, He doesn’t have a maker .上述改成疑问句，先找句子中的动词，需要助动词Do/Does放在句首，动词有三单还原，剩下的照抄，（some many 改成any，遇到第一人称改为第二人称例如I改为you , my 改成your等）句点改成问号。
例如：陈述句：I like the ducks. He likes the dogs.一般疑问句：Do you like the ducks? Does he like the dogs?做出肯定或者否定回答：Yes , I do , Yes ,he doesNo , I don’t . No , he doesn’t . 四．对环线部分提问的题型方法。
