单选题All Eskimos live most of their lives close to salt or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen grow right on rocks. And where there is enough soil, ever grass, flowers and small bushes manage to live. No trees can grow on the Eskimo land, so geographers sometimes call this country the Arctic plains. Some animals, such as rabbits and caribou, eat the plants. Others, like the white fox and grey wolf, eat the rabbits and caribou. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce. The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall almost too short to be noticed. Summer is the good time, when food is usually plentiful. But it is also the time when the Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store. For seldom can enough animals be killed in winter to feed a family. The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21 st and August 21 st , the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sun shining at all. Around Oct. 21 st the Eskimos of Northern Greenland see the sun setting straight south of them, and they don"t see it again until February 22 nd . All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker. Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and the moon provide a little light. The northern lights also help the Eskimos to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo"s eyes.

单选题A recent report on population trend conducted by the think (1) of the World watch Institute identifies signs of slowing growth in some countries. It says populations in 32 countries—all in the industrialized world—have stabilized because of declining birthrates. But in a handful of developing countries where population is slowing, the cause isn't something to (2) , because more people are dying. This trend is called "population fatigue", and it's beginning in many of the developing countries that have experienced (3) birthrates and sharp population growth for several decades. Governments in these countries are now having trouble dealing with feeding, housing and educating an increasing number of children, (4) at the same time confronting the falling water (5) , deforestation and soil erosion that rapid population growth brings. In these countries any new threat—infectious disease, drought or famine—can become a (6) crisis. AIDS is a case (7) . WHO estimates calculate that one-quarter of the adult population of Zimbabwe and Botswana are infected with the AIDS virus, (8) , these countries stands to lose at least one-quarter of their labor force in the next decade from AIDS alone, a situation (9) since the yellow fever swept through Europe in the 14'h century. Social unrest is also increasing in these countries. One example is the (10) conflict between the Tutsis and the Hutus in Rwanda, where population pressures reduced cropland (11) where it could no longer feed those who lived on it. Demands on the world fisheries and shared water resources are likely to spark similar conflicts. Already the waters of the Nile are so heavily used that little reaches the Mediterranean, so any increase in demand or (12) in allocation will also increase tensions. The bottom line is that human population growth is (13) to slow one way or the other. Developing societies will either recognize problems (14) the horizon and act to encourage smaller families — or unchecked births will have their (15) in rising death rates.

单选题{{B}}Questions 11-15 are based on the following passage:{{/B}} Watercolor is the oldest painting medium known. It dates back to the early cave dwellers who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water. Fresco, one of the greatest of all art forms, is done with watercolor. It is created by mixing pigments and water and applying these to wet plaster. Of the thousands of people who stand under Michlangelo's heroic ceiling in the Sistine Chapel, very few are aware that they are looking at perhaps the greatest watercolor painting in the world. The invention of oil painting by the Flemish masters in the fifteenth century led to a decline in fresco painting, and for the next several centuries watercolor was used mainly as a medium for doing preliminary sketches or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters reinstated watercolor as a serious art form. The English have a notorious love for the outdoors and also a great fondness for small, intimate pictures. The subdued tones of watercolor had a remarkably strong appeal for them.

单选题Most Hong Kong students aged 12 to 25 spend less than an hour a week studying online. However, it is claimed that e-learning (网上学习) may not be as popular among teenagers as commonly supposed. In a survey by the Boys' and Girls' Clubs Association, 55% of 785 young people in Hong Kong said they did not like e-learning. "E-learning is not a very good system because it is so troublesome (麻烦的)," said Patrick, 17-year-old, recalling how his online homework disappeared because of a technical problem. Patrick also said some classmates give their account numbers and passwords (密码) to others so they could help them finish their online homework. Self-discipline (自律) is also necessary. In the survey, 34.3% of the teenagers said lack of self-discipline made it difficult for them to learn more from the Internet. But the teenagers also discovered some advantages in e-learning. About 41 percent of the teenagers said they work together with other Internet users in order to discuss their problems. Registered social worker Yuen Hin-sing said the effectiveness of e-learning is still not yet well supported by research data. He called for more resources to study the effectiveness of online learning.
