句 式
陈述句肯定句变否定句：（一找二加三改）
口诀：有be找be,有情找情，无be无情去求助。
找。
找句子中有无be动词( am ,is ,are ,was ,were),
情态动词（can / could ,may ,must ,will ,would 等）
加。
有be动词，情态动词，助动词，直接在其后加not；
没有的话，找句子的动词，在动词前加don't或doesn't
(第三人称单数，原来动词还原），didn't(过去式，原来动词还原）。
3.改。（some 变any.）
例如：
He is a student. →He isn’t a student.
He was a teacher before. →He wasn’t a teacher before.
He can play football well. →He can’t play football well.
I like apples. →I don’t like apples.
He likes apples. →He doesn’t like apples.
I liked apples before. →I didn’t like apples before.
