单选题A Miracle Cancer Cure
Unless you have gone through the experience yourself, or watched a loved one"s struggle, you really have no idea just how desperate cancer can make you. You pray, you rage, you bargain with God, but most of all you clutch at any hope, no matter how remote, of a second chance at life.
For a few excited days last week, however, it seemed as if the whole world was a cancer patient and that all humankind had been granted a reprieve. Triggered by a front- page medical news story in the usually reserved
The New York Times
, all anybody was talking about on the radio, on television, on the Internet, in phone calls to friends and relatives—was the report that a combination of two new drugs could, as
The New York Times
put it, cure cancer in two years.
In a matter of hours patients had jammed their doctors" phone lines begging for a chance to test the miracle cancer cure. Cancer scientists raced to the phones and fax lines to make sure everyone knew about their research too, generating a new round of headlines.
The time certainly seemed ripe for a breakthrough in cancer. Only last month scientists at the National Cancer Institute announced that they were halting a clinical trial of a drug called tamoxifen—and offering it to patients getting the placebo—because it had proved so effective at preventing breast cancer (although it also seemed to increase the risk of uterine cancer). Two weeks later came The New York Times" report that two new drugs can shrink tumors of every variety without any side effects whatsoever.
It all seemed too good to be true, and of course it was. There are no miracle cancer drugs, at least not yet. At this stage all the drug manufacturer can offer is some very interesting molecules, and the only cancers they have cures so far have been in mice. By the middle of last week, even the most breathless TV talk-show hosts had learned what every scientist already knew: that curing a disease in lab animals is not the same as doing it in humans. "The history of cancer research has been a history of curing cancers in the mouse," Dr. Richard Klausner, head of the National Cancer Institute, told the Los Angles Times. "We have cured mice of cancer for decades--and it simply didn"t work in people."

单选题The air is polluted. The earth is poisoned. Water is unsafe to drink and garbage is burying the civilization that produced it. Our environment is being polluted faster than nature and man's efforts can prevent it, Time is bringing us more people, and more people will bring us more industry. More people and more industry will bring us more motorcars, larger cities, and the growing use of man-made materials. This is happening not only in advanced societies but also among the developing nations as they become industrialized. Now many scientists are worrying about the possibility of world pollution. Some experts declare that the balance of nature is being so upset that the very survival of human beings in danger. What can solve this problem? The fact is that pollution is caused by man--by his greed and his modern way of life. We make "increasing industrialization(工业化)" our chief aim. For its sake we are willing to sacrifice everything: clean air, pure water, good food, our health, and the future of our children. There is a constant flow of people from the country into the cities, eager for the benefits of modern society. But as our technological achievements have grown in the last twenty years, so in that time pollution has became a serious problem. Isn't it the time we should stop and ask ourselves where we are going--and why? It reminds one of the stories about the airline pilot who told his passengers over the loud speakers: "I've some good news and some bad news. The good new is that we're making rapid progress at 530 miles per hour. The bad news is that we're lost and don't know where we're going." The sad fact is that this becomes a true story when applied to our modern society.

单选题Common-cold Sense
You can"t beat it, but you don"t have to join it. Maybe it got the name "common cold" because it"s more common in winter. The fact is, though, being cold doesn"t have anything to do with getting one. Colds are caused by the spread of rhinoviruses, and, at least so far, medical science is better at telling you how to avoid getting one than how to get rid of one.
Children are the most common way cold viruses are spread to adults, because they have more colds than adults—an average of about eight per year. Why do kids seem so much more easily to get colds than their parents? Simple. They haven"t had the opportunity to become immune to many cold viruses.
There are more than 150 different cold viruses, and you never have the same one twice. Being infected by one makes you immune to it—but only it.
Colds are usually spread by direct contact, not sneezing or coughing. From another person"s hand to your hand and then to your nose or eyes is the most common route. The highest concentration of cold viruses anywhere is found under the thumbnails of a boy, although the viruses can survive for hours on skin or other smooth surfaces.
Hygiene is your best defense. Wash your hands frequently, preferably with a disinfectant soap, especially when children in your household have colds.
But even careful hygiene won"t ward off every cold. So, what works when a coughing, sneezing, runny nose strikes?
The old prescription of two aspirins, lots of water, and bed rest is a good place to start. But you"ll also find some of the folk remedies worth trying. Hot mixtures of sugar (or honey), lemon, and water have real benefits.

单选题Industrial pollution is not only a problem for the countries of Europe and North America. It is an extremely serious problem in some developing countries. For these counties, economic growth is a very important aim. They want to introduce industries, and so they put few controls on industries which cause pollution. Cubatao, an industrial town of 85,000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants(污染物). The people of the town are suffering from the poisonous matters in their surroundings, and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and grown-ups, lung problems are sometimes twelve times more common in Cubatao than in other places. It is true that Brazil, like many other countries, has laws against pollution, but these laws are not carried out strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines(罚款)than to buy the expensive equipment that will reduce the pollution, It is clear, therefore, that economic growth is more important to the 'government than to the health of the workers. However, the responsibility(责任) does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U.S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely(严厉的)punished or even put out of business.

单选题As soon as Linda went into the department that sold raincoats, she sensed there was something unusual in the atmosphere. First of all, there was a salesman there and not a saleswoman. That was very unusual in the women's coat department. The salesman asked if he could be of any help. But when she said she was just looking he did not seem to be listening. He (lid not look very much like a salesman, either. A second later a raincoat caught her eye. Site asked him a question about it. He did not even hear her at first. She asked again. She wanted to know if he had any coats like it with a detachable (可分离的) lining. He did not seem to understand what a detachable lining was. She explained. Then she went on looking. She noticed that the salesman seemed to be watching another customer in the department all the time. The other customer, a middle-aged woman, left the department. The salesman immediately went to the phone and told somebody on the other end that the woman had gone and had definitely taken two leather belts without paying for them. Then he turned to Linda and explained that he was not a salesman at all but a store detective. Later, Linda read in the paper that a woman had been arrested for stealing some belts front a department store, or, in other words, for shoplifting.
