A
Drinking too much alcohol（酒，酒精）seems to give pleasure to many people. Habit alone can keep people drinking. However, many heavy drinkers can offer some other reasons for their actions.
Right now doctors are getting some attention in their protests against heavy drinking. Many people have cut down on their drinking. In general, everyone believes the doctors' warnings.
It is sometimes very easy to stop drinking heavily. For example, at a party a man has just one drink. He can stop thinking about having another one. Both health considerations(考虑) and the high cost of drinking help him to stay away from alcohol. All of his friends help, too. They always understand his problem and are really concerned（关注）. The heavy drinker needs friends like these.
