单选题In 1987, there were over 1.5 million violent crimes reported in the United States. Most of this violence comes from aggressive people. Psychologists are trying to understand the cause of aggressive behavior that results in injury or death. Psychologists say that extreme aggression runs in families. In other words, if your parents are very aggressive, there is a strong possibility that you will be too. A team of researchers recently studied a large group of children over a 22-year period. The researchers discovered that the aggressive children grow up to become aggressive adults. Furthermore, the males are likely to have criminal records before the age of 30. This pattern continues as the aggressive adults in turn severely punish their own children. When a child's aggressive behavior becomes part of his or her character, it is not easy to change. Therefore, it is important to try to prevent it before adolescence, many psychologists believe that watching violence on television may cause children to become aggressive. One solution may be that parents forbid their children to watch violent television programs. Aggressive behavior in very young children should be immediately stopped by the parents before it becomes more severe. Other researchers have found that men are more aggressive than women. Although this seems to be socially acceptable, there is also a biological reason for this difference. Very aggressive people have a low amount of a chemical serotinin in the brain. This is true for both men and women. In general, though, men have lower level of serotinin. There are different patterns of aggressive behavior. One type is chronic aggression. Another type of aggressive behavior is impulsive. That is, the violent actions are sudden and unpredictable. Researchers have discovered that some people who are impulsively aggressive can be helped by a medication called lithium (锂). Lithium seems to stabilize the serotonin level in the brain. Scientists have tested this drug with laboratory animals. Lithium effectively reduced their aggressive behavior. In general, psychologists agree that aggressive behavior should be treated in childhood before the behavior becomes permanent. However, some children will grow up to become violent adults and may hurt themselves or others. Lithium and other medications may be an effective treatment for them.

单选题Floods, storms and other natural events kill thousands of people every year. So does extreme heat. Experts say heat may be nature's deadliest killer. For example, extreme heat was blamed for killing more than one hundred people in India and Pakistan in two thousand seven. Daytime temperatures rose to more than forty-five degrees Celsius in some areas. On June eleventh, the temperature in one desert town hit fifty-one degrees. Experts say the total heat of a hot day or several days can affect health. Several hot days are considered a heat wave. Experts say heat waves often become dangerous when the nighttime temperature does not drop much from the highest daytime temperature. This causes great stress on the human body. Doctors say people can do many things to protect themselves from the dangers of extreme heat. Stay out of the sun, if possible. Drink lots of cool water. Wear light colored clothing made of natural materials. Make sure the clothing is loose, permitting freedom of movement. And learn the danger signs of the medical problems that are linked to heat. The most common health problem linked to hot weather is heat stress. Usually, it is also the least severe. The causes of heat stress include wearing heavy clothing, physical work or exercise, hot weather or high humidity. Humidity is the amount of water in the air. If several of these conditions are present at the same time, a person's body temperature may rise above safe limits. The person loses large amounts of body water and salt in perspiration. Perspiration is one of the body's defenses against heat. It is how the body releases water to cool the skin. Most people suffer only muscle pain as a result of heat stress. The pain is a warning that the body is becoming too hot. Doctors say those suffering muscle pain should stop all activity and rest in a cool place. They should also drink cool liquids. Do not return to physical activity for a few hours because more serious conditions could develop. So experts advise drinking more water in hot weather. Doctors say actions other than drinking water can protect against the death dangers of heat. Stay out of the sun, if possible. Wear loose, light-weight and light colored clothes. Wear a hat or other head covering when in the sun. Eat fewer hot and heavy foods. If possible, cook foods during cooler times of the day. Also, rest more often. Physical activity produces body heat. Experts say these simple steps can prevent the dangerous health problems linked to heat. They will prevent sickness, help you feel better and may one day even save your life.

单选题 It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important. Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life. Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.

单选题 A report consistently brought back by visitors to the US is how friendly, courteous and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet it is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of diversion, and brought news of the outside world. The harsh realities of the frontier also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest cabin or settlement. It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers. It reflected the harshness of daily life: if you didn't take in the stranger or take care of him, there was no one else who would. And someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the weary traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist trails. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner-amazing. " Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships. And, of course, speaking a language does not necessarily mean that someone understands social and cultural patterns. Visitors who fail to "translate" cultural meanings properly often draw wrong conclusions. For example, when an American uses the word "friend", the cultural implications of the word may be quite different from those it has in the visitor's language and culture. It takes more than a brief encounter on a bus to distinguish between courteous convention and individual interest. Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.

单选题Although many governments try to convince their respective subjects that atomic energy is an acceptable alternative 21 the burning of fossil fuels, no government has taken the least trouble to explain the dangers. Maybe they are 22 them. 23 the reason, the public must learn by experience, even though this 24 may be catastrophic. While it is true that nuclear reactors do not produce visible smoke, it is certainly not 25 that they do not pollute. And the pollution they produce is much more insidious precisely because it is 26 . 27 inconvenient it may be for governments to publish all the facts, they have no moral excuse for not doing so, 28 they think they are acting in our best interest. At least some of the facts are known, even though they are not widely reported. Nuclear reactors produce radioactive water and gases in vast 29 . What 30 all this waste? It is 31 concrete tanks and stored on tank farms. It is 32 in disused salt mines. It is run into fractured rock. It is buried. It is 33 about in special trains. But even when dumped, it has to be kept 34 by sprinklers to stop it from boiling. And the contents of the tanks are, of course, extremely corrosive. The efforts of a fracture in the tank or a failure of the cooling system would be 35 . While every effort is made to 36 that radioactive wastes do not except into the sea or 37 supplies of drinking water, such a leakage would be too horrible 38 contemplate. But even then, governments would presumably continue to belittle the hazards. It seems that 39 governments can get away with not telling the truth, they will continue to keep silent. Nevertheless the people 40 to know the full facts. Do you know what happens to the radioactive waste in your country? No? Well—find out!
