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.
