小升初专项：陈述句变否定句

一、变否定句：1.当谓语动词是be动词,am, is are或者过去时was, were时，直接在这些词后面加not构成否定形式，即am not, is not=isn’t , are not=aren’t。
如果句子里有some，在否定句中要变成any。
and 变成or。
Eg. She is a beautiful girl. (改为否定句)- She isn’t a beautiful girl.There are some students in Sun school. (改为否定句)-There aren’t any students in Sun school.2.当句子中谓语动词是助动词will,情态动词can, could, should,must等时，直接在助动词和情态动词后加not 变为否定句。
注意will not = won’t, can not=can’t, must not =mustn’t 表示禁止。
如果句子里有some，在否定句中要变成any。
and 变成or。
Eg .My family will go to Beijing and Qingdao next Sunday . (改为否定句)-My family will not go to Beijing or Qingdao next Sunday.They can run very fast. (改为否定句)-They can’t run very fast.3.Eg.谓语动词是行为动词而又没有助动词或情态动词时，必须在谓语动词前加助动词，一般现在时加助动词do ，第三人称单数加does，一般过去时加did，再和not构成否定结构。
don't, doesn't, didn't后都用动词原形。
