单选题Visitors to this country are normally admitted for six months, but foreign students can usually stay for one year. They must 1 an educational institution, and they are required to study for a minimum of fifteen hours a week on a 2 course. Prospective students have to show that they can afford their studies, and that they have sufficient 3 resources to support themselves 4 in this country. In order to work here the foreigner needs a work permit, 5 must be applied for by his prospective employer. The problem here is that the Department of Employment has the fight to grant or 6 these permits, and there is little that can be done 7 it; it would be extremely unwise for a foreign visitor to work 8 a permit, since anyone doing so is liable to immediate deportation (驱逐出境). There are some people from the Common Market countries, who are often given 9 residence permits of up to five years. Some other people, such as doctors, foreign journalists, authors and others can work without permits, and foreign students are normally allowed to 10 part-time jobs while they are studying here.

单选题The fundamental dilemma of computer-based instruction and other IT-based educational technologies is that their cost effectiveness compared to other forms of instruction—for example, smaller class sizes, self-paced learning, peer teaching, small group learning, innovative curricula, and in-class tutors—has never been proven. So why are we, as a nation, so fascinated with computers in childhood? This one-size-fits-all fix for elementary schools does seem to meet a lot of adult needs. It makes politicians and school administrators appear decisive and progressive. It tempts overworked parents and teachers with a convenient electronic baby-sitter. And it is irresistible to high-tech companies that hope to boost sales in the educational market. But a machine-centered approach does not meet the developmental needs of grade-school children. Nor will it prepare them to develop the human imagination, courage, and will power they will as adults need to tackle the huge social and environmental problems looming before us. Young children are not emotionally, socially, morally, or intellectually prepared to adapt themselves to the constraining logical abstractions that computers require. This inactive approach to learning is also unhealthy for their developing senses and growing bodies. What"s good for business is not necessarily good for children. We cannot afford educational policies that will expand the market for Microsoft, Compaq, IBM, Apple, and other companies at children"s expense. Nor can we afford the fantasy that pushing young children to operate the very latest technological gadgets will somehow save them from economic and cultural uncertainties in the future. Nothing can do that—certainly not soon-to-be outdated skills in operating machines. In the long term, what will serve them far better is a firm commitment from parents, educators, policy-makers, and communities to the remarkably low-tech imperatives of childhood. Those include good nutrition, safe housing, and high-quality health care for every child—especially the one in five now growing up in poverty. They also include consistent love and nurturing for every child; active, imaginative play; a close relationship to the rest of the living world; the arts; and lastly time—plenty of time for children to be children. A new respect for childhood itself, in other words, is the gift that will best prepare our children for the future"s unknowns. Empowered by this gift, our children can grow into strong and creative human beings, facing tomorrow"s uncertainties with competence and courage. School reform is a social challenge, not a technological problem. The Education Department"s own 1999 study, "Hope in Urban Education," offers powerful proof. It tells the story of nine troubled schools in high-poverty areas, all places resigned to low expectations, low achievement, and high conflict. But all transformed themselves into high-achieving, cohesive communities. In the process, everyone involved—principals, teachers, other staff members, parents, and students—developed high expectations of themselves, and of each other. The strategies that worked in these schools, the study emphasizes, were persistence, creativity in devising new ways of collaborating, maximizing the attention focused on each child, and a shared commitment to meeting the full range of children"s needs. Perhaps what we"re looking for is not a technology, not a product to be bought and sold at all. Perhaps the gold is something to be dug and refined within ourselves.

单选题The marvelous telephone and television network that has now enmeshed the whole world, making all men neighbors, cannot be extended into space. It will never be possible to converse with anyone on another planet. Even with today's radio equipment, the messages will take minutes—sometimes hours—on their journey, because radio and light waves travel at the same limited speed of 186, 000 miles a second. Twenty years from now you will be able to listen to a friend on Mars, but the words you hear will have left his mouth at least three minutes earlier, and your reply will take a corresponding time to reach him. In such circumstances, an exchange of verbal messages is possible—but not a conversation. To a culture which has come to take instantaneous communication for granted, as part of the very structure of civilized life, this "time barrier" may have a profound psychological impact. It will be a perpetual reminder of universal laws and limitations against which not all our technology can ever prevail. For it seems as certain as anything can be that no signal--still less any material object—can ever travel faster than light. The velocity of light is the ultimate speed limit, being part of the very, structure of space and time. Within the narrow confines of the solar system, it will not handicap us too severely. At the worst, these will amount to twenty hours—the time it takes a radio signal to span the orbit of Pluto, the outer-most planet. It is when we move out beyond the confines of the solar system that we come face to face with an altogether new order of cosmic reality. Even today, many otherwise educated men—like those savages who can count to three but lump together all numbers beyond four—cannot grasp the profound distinction between solar and stellar space. The first is the space enclosing our neighboring worlds, the planets; the second is that which embraces those distant suns, the stars, and it is literally millions of times greater. There is no such abrupt change of scale in the terrestrial affairs. Many conservative scientists, appalled by these cosmic gulfs, have denied that they can ever be crossed. Some people never learn ; those who sixty years ago scoffed at the possibility of flight, and ten years ago laughed at the idea of travel to the planets, are now quite sure that the stars will always be beyond our reach. And again they are wrong, for they have failed to grasp the great lesson of our age— that if something is possible in theory, and no fundamental scientific laws oppose its realization, then sooner or later it will be achieved. One day we shall discover a really efficient means of propelling our space vehicles. Every technical device is always developed to its limit and the ultimate speed for spaceships is the velocity of light. They will never reach that goal, but they will get very near it. And then the nearest star will be less than five years voyaging from the earth.

单选题Some people seem to think that sports and games are unimportant. They like to watch TV at home, go to the cinema, or sleep. (21) in fact sports and games can be (22) great value, especially to people who work with their brains (23) of the day. Sports and games should not be treated only as amusements (娱乐活动). They can (24) our bodies, prevent us (25) getting too fat, and keep us healthy. But these are not their only uses. They give us valuable practice (26) helping the eyes, brain and muscles (肌肉) to work together. In table tennis, the eyes can see the ball (27) , judge its speed and direction, and pass this information (28) to the brain. The brain then has to decide what to do, and sends its orders to the muscles of the arms, legs, and so on, (29) the ball is met and hit back (30) the player wants it to go. All this must happen (31) a very quick speed, and only those (32) have had a lot of practice at table tennis can do this successfully. Sports and games are also very useful (33) character-training. In their lessons at school, boys and girls (34) learn about such virtues(品德) as courage, discipline(纪律), and love (35) one's country.

单选题A new study by the Development of Health in Taiwan shows that more than half of the adult population in Taiwan lacks an understanding of health problems. More than 2,000 adults took part in the survey to find out about their knowledge of diet, health-care, disease control and medicine. Surprisingly, only 51% of the people surveyed understand that common cold has no cure, and taking medicine is absolutely no use at all. The problem is mad worse by doctors who give their patients large doses of useless drugs. More than two-thirds believe that it is only the nicotine in cigarettes rather than the other chemicals that causes cancer. These people believe that if they smoke “light” cigarettes with less nicotine, they will lead to more illness, suffering and early death. But the outlook for health education in Taiwan is not all negative. The survey concludes that younger Taiwanese have a better understanding of health concerns than their parents, while senior citizens have the least understanding among the three age groups.

单选题Eating in space is different from eating on earth. The food that astronauts carry with them does not look like the food you eat. Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the spaceship the astronaut puts the water back. He "shoots" hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs. Crumbs would float around the spaceship and get in the way. Meat and cake often come in bite-sized pieces. Astronauts can't drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat this way.

单选题Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form a crust of rock that was many miles thick. Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials. In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart. The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents-and became the several oceans and seas we know today.
