Why didn’t Linda’s father want her to study in the United States？

It is possible to stop most drug addiction in the United states within a very short time. Simply make all drugs available and sell them at cost. Label each drug with a precise description of what effect-good and bad-the drug will have on the taker. This will require heroic honesty.

For the record, I have-once-almost every drug and like none, disproving the popular theory that taking a single smoke of opium will enslave the mind. Nevertheless many drugs are bad for certain people to take and they should be told why in a sensible way.

Along with advice and warning, it might be good for our citizens to recall that the United States was the creation men who believed that each man has the right to do what he wants with his own life as long as he does not interfere with his neighbor’s pursuit of happiness.

Now one can hear the warning，if everyone is allowed to take drugs, everyone will, and the gross national product will decrease and we shall end up a race of fools. Alarming thought. Yet it seems most likely that any reasonably healthy-minded person will become a drug addict if he knows in advance what addiction is going to be like.

Is everyone reasonably sensible? No. Some people will always become drug addicts just as some people will always become drunken, and it is just too bad. Every man, however, has the power to kill himself if he chooses. But since most men don’ t, they won’t be the majority, either. Nevertheless, forbidding people things they like or think they might enjoy only makes them want those things all the more. This psychological insight is ，for some mysterious reason ,denied by our governors.

The author’s solution to the drug problem is______.

A．to make ail drugs extremely costly

B．to put honest warnings on all drug labels

C．to make the buying and selling of ail drugs illegal

D．to tell people the dangerous effects of drugs on health

听力原文：W: So you know what the White Lane Law is?

M: In the United States, each state has a law that says blind people using canes or dogs have the same rights of public access as the sighted.

W: What does it mean, then?

M: It means that blind people can take their canes and dogs into public buildings, offices, restaurants, theaters, amusement parks, on houses, trains, planes and other public places. These laws were established from the work of the US National Federation of the Blind to make sure that blind people have the same rights as everyone else.

W: Why do some blind people use dogs and others use canes?

M: it is simply a matter of personal choice. Some blind people like using canes better, and some enjoy using dogs.

W: Should I help a blind person across the street?

M: If a blind person asks for help, then you may certainly help. You can ask if any help is needed, but understand that the answer may be "no", Blind people, if they have learned to use a cane or dog and travel independently, may not need help. It is important not to grab someone who is blind. If a blind person wants help, he or she may take your arm, or simply walk beside you. Some blind persons may have a harder time hearing the cars and traffic, especially if there is construction or a lot of noise around the area. Then they might want help that they might not need at other times.

W: Should I help a blind person to a chair?

M: The same rules apply here. Some blind people will appreciate help in locating a chair, but some can find chairs, tables, and desks on their own. Sometimes a blind person may ask where the chairs or tables are, then go to them on his or her own.
