单选题Passage 2 For several years, scientists have been testing a substance called interferon (干扰素), a potential wonder drug that is proving to be effective in treating a variety of ailments, including virus infections, bacteria infections, and tumors. To date, the new drug has provoked no negative reaction of sufficient significance to discourage its use. But in spite of its success, last year only one gram was produced in the entire world. The reason for the scarcity lies in the structure of interferon. A species of specific protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so powerful that the amount given each patient per injection is very small. Unlike antibiotics, interferon does not attack germs directly. Instead, it makes unaffected cells resistant to infection, and prevents the multiplication of viruses within cells. As you might conclude, one of the most dramatic uses of interferon has been in the treatment of cancer. Dr. Hans Strander, research physician at Sweden's famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who has undergone surgical procedures for advanced cancer, half were given interferon. The survival rate over a three-year period was 70 percent among those who were treated with interferon as compared with only 10 to 30 percent among those who have received the conventional treatments. In the United States, a large-scale project supported by the American Cancer Society is now underway. If the experiment is successful, interferon could become one of the greatest medical discoveries of our time.

单选题 Passage Three Visiting a National Park can be relaxing, inspiring and rejuvenating, but it can also be disturbing. As you drive into Rocky Mountain National Park, and you will see starving elk, damaged meadows and dying forests. Our parks are growing old because we have mistakenly protected them from natural processes, such as fire, predation, and insects. We believed that we were saving these remnants of wild America, but actually we have "protected" them to death. If we want to save our National Parks, the National Park Service must change its management priorities to-prevent over population of animals and to restore natural process in the forest in order to prevent their stagnation and "death" by old age. We must act soon: our parks are dying of old age because we have altered the forces in nature that keep them young and strong. By tracing the history of our National Parks, we can understand the problem and see why we need active management. In the early part of the 20th century, settlers exploited wildlife heavily, resulting in near-extinction of many species. Therefore, several National Parks were established by Congress primarily to save endangered animals. However, stricter wildlife protection laws and improved wildlife management techniques resulted in greater populations of animals overcrowding in areas of high concentration, such as the Yellowstone elk herds. Complicating the problem, the National Park Service in the early part of the 20th century adopted a policy of aggressive predator elimination, thus reducing natural wildlife population control. Subsequently, elk and deer populations exploded in many National Parks, resulting in severe damage to native vegetation. Vigorous forest fire and insect suppression in the National Parks throughout the 20th century further altered the natural environment by allowing forests to over-mature, without natural thinning processes. Park managers thought that they were protecting the land, but actually they were removing important controls from the forest ecosystems. Clearly, we must act immediately if we want to pass down to our children and grandchildren the green legacy of our National Parks; we must step in and restore the natural processes which we have altered through our well-intentioned, but misguided, policies in the past.

单选题Oxford is a very old town on the River Thames, about 60 miles from London. Unlike modern university towns, where you usually find the university on the edge of the town, or on its own campus (校园), Oxford's center is the university; and all around the crossroads at the very heart of Oxford, Carfax, there are grey stone colleges and other university buildings. In the center you can also find interesting old restaurants. There are a lot of churches, and a few really large and interesting buildings, such as the Ashmolean Museum, the "round" library, the Bodleian and Radcliffe Camera. Like all English towns, there are parks, and one" The Parks" is the home of university cricket(板球) in the summer months. As you leave the center and go towards the edge of Oxford you can see industrial areas in one direction; and in another, beautiful suburbs(郊区). There is, in fact, quite a lot of industry in Oxford.

单选题Prolonged and excessive use of alcohol can seriously undermine an individual's health. Physical deterioration occurs. Large quantities of alcohol can directly damage body tissue and indirectly cause malnutrition. Nutritional deficiencies can result for several reasons. Alcohol contains empty calories, which have no significant nutritive value. When consumed in substantial amounts, alcohol curbs one' s appetite for more wholesome foods. Excessive alcohol intake can interfere with the proper digestion and absorption of food. Therefore, even the heavy drinker who does eat a well-balanced diet is deprived of me essential nutrients. Maintenance of a drinking habit can deplete economic resources otherwise available for buying good, wholesome food. Malnutrition itself further reduces the body' s ability to utilize the nutrients consumed. The result of damaged tissue and malnutrition can be brain injury, heart disease, diabetes, or cancer of the liver, and weakened muscle tissue. Untreated alcoholism can reduce one's life span by ten to twelve years. Heavy alcohol consumption also affects the body's usage of other drugs and medications. The dosages required by excessive drinkers may differ from those required by normal or non-drinkers. Serious consequences can be incurred unless the prescribing physician is aware of the patient's drinking habits. Sudden death may result from excessive drinking. It might occur when the individual has ingested such a large amount of alcohol that the brain center controlling breathing and heart action is adversely affected, or when taking some other drugs, particularly sleep preparations along with alcohol. Death, as a result of excessive drinking, can come during an automobile accident since half of all fatal traffic accidents involve the use of alcohol. Many self-inflicted deaths, as well as homicides, involve the use of alcohol. It is important to remember that alcohol is a drug that is potentially addictive. Once the user is hooked on alcohol, withdrawal symptoms occur when it is not sufficiently available to body cells. At the onset of developing alcohol addiction, these symptoms may be relatively mild and include hand tremors, anxiety, nausea, and sweating. As dependency increases, so does the severity of the withdrawal syndrome and the need for medical assistance to cope with it. In 1956 the American Medical Association supported the growing acceptance of alcoholism as an illness, falling under the treatment jurisdiction of the medical profession. Since then, the medical resources for problems of acute and chronic intoxication have increased and improved.
