He doesn’t like meat at all.为什么要加do啊?

He doesn't like meat at all.为什么要加do啊?
He doesn't like meat at all.
为什么要加do啊?
如果是我自己写这句话我会这样写
He not like meat at all.

句子变否定有几种：
1 谓语是be,直接在be后加not,
如,Iam a teacher.I am not a teacher.
2 谓语有情态动词,在情态动词后加not
如,He can sing.He can't sing.
3 不属于上两类者,加助动词do,加not
如,He sings well.He doesn't sing well.
