When I saw some students dominated by alcohol，tobacco or drug，I made up my mind to help them “delete” the bad habits.To facilitate a positive change was why I set up a team which was     1    of surgeons，specialists in psychology，consultants and dentists，who would regularly deliver speeches to     2    these students’ awareness of physical health.Students were repeatedly informed of some tips on how to get out of a pessimistic or negative state，how to stay dynamic and how to get     3    when they were stressed out or worn out.To these students，to be examined on a monthly basis was necessary.They were also advised to participate in bowling matches，go to skateboarding or go to see a comedy to stimulate their enthusiasm in life.Students were given sugary cookies or nuts straight away if they felt     4    or got the flu.Through these activities，most students     5     changing their bad habits in reward for our help.They would rely on self-discipline to govern themselves and could be     6    in studying instead of skipping classes.They promised to behave themselves in response to our patient guidance.
