These conditions continued until after World War Ⅱ. At that time, new treatments were discovered for some major mental illnesses considered untreatable (penicillin for syphilis of the brain and insuered for some major mental illnesses considered untreatable (penicillin for syphilis of the brain and insulin treatment for schizophrenia and depressions)), and a succession of books, motion pictures, and newspaper exposes called attention to the plight of the mentally ill. Improvements were made, and Dr. David Vail's Humane Practices Program is a beacon for today. But changes were slow in coming until the early 1960s. At that time, the Civil Rights Movement led lawyers to investigate America's prisons, which were disproportionately populated by blacks, and they in turn followed prisoners into the only institutions that were worse than the prisons—the hospitals for the criminally insane. The prisons were filled with angry young men who, encouraged by legal support, were quick to demand their right. The hospitals for the criminally insane, by contrast, were populated with people who were considered "crazy" and who were often kept obediently in their place through the use of severe bodily restraints and large doses of major tranquilizers. The young cadre of public interest lawyers liked their role in the mental hospitals. The lawyers found a population that was both passive and easy to champion. These were, after all, people who unlike criminals, had done nothing wrong. And in many states, they were being kept in horrendous institutions, and injustice, which once exposed, was bound to shock the public and, particularly, the judicial conscience.
Judicial interventions have had some definite positive effects, but there is growing awareness that courts cannot provide the standards and the review mechanisms that assure good patient care. The details of providing day-to-day care simply cannot be mandated by a court, so it is time to take from the courts the responsibility for delievery of mental health care and assurance of patient rights and return it to the state mental health administrators to whom the mandate was originally given. Though it is a difficult task, administrators must undertake to write rules and standards and to provide the training and patient rights are respected.
The main purpose of the passage is to ______.
A．discuss the influence of Dorothea Dix on the mental health movement
B．provide an historical perspective on problems of mental health care
C．increase public awareness of the plight of the mentally iii
D．shock the reader with vivid descriptions of asylums
听力原文： The food we eat seems to have produced profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that eight percent of all human illnesses are related to diet and forty percent of cancer is relined to the diet as well, especially cancer of the colon (结肠). Different cultures are more prone to contract certain illness became of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates (硝酸盐) and nitrites (亚硝酸盐), commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult to know which things on the packaging labels of processed foods are helpful or harmful. The additives that we eat are not all so direct. Farmers often give penicillin to beef and administered to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animal in order to obtain a higher price on the market, Although the Food and Drug Administration has repeatedly tried to control these procedures, the practices continue.

A．It has made many additives.
B．It has caused most cancers.
C．It makes some cultures more prone to cancer.
D．It has made many foods unfit to eat.
听力原文：W: Good afternoon, sir. What can I do to help？
M: Oh, I have a terrible cold. Apart from that, I have a headache. Can you suggest something I can take to relieve the pain？
W: Don't you have a prescription？
M: No, I haven't gone to see a doctor.
W: Are you allergic to any type of medication？
M: I don't know exactly. I think that I can take most drugs.
W: OK then, I recommend this brand for quick relief.
M: Will this really help？
W: According to the label, yes. But if that doesn't help, then drink a cup of hot tea along with some honey. There's no miracle drug to cure a common cold.
M: Which are the best headache tablets？
W: We have a number of them. They are all very good.
M: Can you sell me penicillin？
W: Sorry, sir. I cannot sell it; you must first get a doctor's certificate or prescription.
M: Well, then, give me some boric acid.
W: All right. This is a common medicine.
M: Do you have any cough syrup and lozenges？
W: Yes, of course.
M: That's great.
W: Here you are. The instructions on it tell you how to take it. Make sure you read them carefully.
M: Thank you for reminding me.
W: Please pay special attention to this cough syrup. Shake the bottle before you take it.
M: Thank you very much indeed.
W: Anything else？
M: No, thank you.
W: You're welcome. I hope you will recover in no time.

D．Penicillin.
Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day these days on the issue of nuclear energy. Give it back, say some of the voices, it doesn' t really work, we' ve tried it and it doesn' t work, go back three hundred years and start again on something else less chancy for the race of man.
The principle discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty - Newtonian mechanics, for example - have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.
Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today' s imagining.
It is not just that there is more to do, there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.
What can' t be inferred from the 1 st paragraph？
A．Scientific experiments in the past three hundred years have produced many valuable items.
B．For three hundred years there have been people holding hostile attitude toward science.
C．Modern civilization depends on science so man supports scientific progress unanimously.
D．Three hundred years is not long enough to settle back critical appraisal of scientific method.
