know不能直接加not否定
如果不清楚,请看�
I am not a student.
am就可以直接加not否定

learning能直接做谓语吗?
I learning English. *
不能

I am learning English.
am帮助了learning去做谓语

We are making model planes.
2 be语态助动词
The apple was eaten by Jack.
The boy was praised by his father.
3 have/has时态助动词
I have finished my homework.
Jack has eaten the apple.
