there＇ an old chinee aying: "the teacher i not qualified, if he i not trict with hi tudent." o we can ee that in former time the relation between tudent and teacher were eriou and formal. but nowaday, maybe becaue of the wetern influence, thi kind of re lation become le formal and more friendly, epecially at college and univeritie.
college tudent don＇t have to tand up when the teacher come into the claroom. tudent are generally encouraged to ak quetion during cla, to go to the profeor＇ office for help or to have a dicuion with the tutor after cla, and to phone if they need help in their leon.
however, tudent are till epected to be polite to their teacher. when tudent want to ak quetion, they uually raie their hand firt and wait until they＇re allowed to peak. but if a profeor i giving a formal lecture, it i the wrong time to ak a quetion. if you de o, you are rude enough to offend the lecturer and the other clamate.
