回複：是非是判斷事情的重要原則。

This teacher speak English very quickly and pronounce half words.As you listen,you often lose the track of what he said.He think he is American Asian,he speak arrogently and casually,not taking students seriously.I heard other students say if student is late 10 min for the exam,he will lock the door and keep you out.Most of students never speak in class.
It is not that I don't like the teacher.That cann't be the reason that he hates me,right?I will see if he goes on behaving in such a rude manner,I am sure to report it to school.I am sure to behave myself well.

Thank all replies.
