III. Reading Comprehension (30 points, 2 points for each item)

　　Passage One

　　Questions 21 to 25 are based on the following passage.

　　Alcohol affects the brain; and its immediate effects are more marked on

　　those who are not used to the drug than on regular drinkers. It is not a

　　stimulant but a depressant, which adversely affects concentration, removes

　　inhabitations, and increases the risk of accidents. Under the influence of

　　alcohol people are less able to exercise self-control and may say and do

　　things that they afterwards regret-----perhaps for the rest of their

　　lives. For example, a girl who does not wish to have a baby may be made

　　pregnant by a man whom she would not have chosen as the farther of her

　　child; and a man may make pregnant a woman whom he would not have chosen

　　as the mother of his child. Some other forms of drug taking, like drinking

　　alcohol and smoking tobacco, are part of group behavior. Such drug taking

　　is encouraged by those who are already addicted to the drug, and by those

　　who profit by making and selling the drug. 

　　I mean one who starts taking a drug may soon become addicted to it. As

　　with all bad habits, it is better not to start drug taking than to suffer

　　the physical and emotional harm caused by the drug and to have the problem

　　of trying to break the addiction. It is best, therefore, to refuse the

　　drugs that is offered. Apart from other considerations, drugs that come

　　from unreliable sources (because their manufacturer and distribution is

　　against the law.) and not available in carefully measured and doses and

　　their purity are not guaranteed. Their effects are unpredictable and they

　　may well be dangerous. If such drugs are offered by so-called friends you

　　wouldn’t be well advised to find new friends, who share your values, and

　　to continue being yourself.
