A number of parents prefer not to send their children to school. (1) There are about 300,000 home-schoolers in the United States today. Some parents prefer teaching their children at home because they do not believe that public schools teach the correct religious values; others believe they can provide a better educational experience for their children by teaching them at home. (2) David Gtisterson and his wife teach their three children at home. Guterson says that his children learn very differently from children in school. (3) For example, when there is heavy snowfall on a winter day, it may start a discussion or reading about climate, snow removal (去除) equipment, Alaska, polar bears (北极熊), and winter tourism. A spring evening when the family is out watching the stars is a good time to ask questions about satellites and the space program. (4) Home schooling is often more interesting than regular schools, but critics say that home-schoolers are outsiders who might be uncomfortable mixing other people in adult life. (5) However, most parents don’t have the time or the desire to teach their children at home, so schools will continue to be where most children get their formal education. A. Interestingly, results show that home-schooled children quite often do better than average on national tests in reading and math. B. Critics also say that most parents are not well qualified to teach their children. C. Learning starts with the children’s interests and questions. D. Children who are educated at home are known as "home-schoolers". E. In some countries, however, children are educated by their parents. E If the Brazilian rain forests are on the TV news, it could be a perfect time to talk about how rain forests influence the climate, and how deserts are formed.

Text 5 The air surrounding us is important to everyone. Without air, we could not exist. Everyone understands that. But air is necessary in many other ways — ways that are not always so obvious or widely known. If we did not have air, there would be no sound. Sound travels through air. Where there is no air, there is no sound. Without air there would be no fire. There would be no automobiles, since motors need air in order to operate. Without air, there would be no wind or clouds. The night time would be very cold and the days very hot. We would be forced to seek shelter from the sun, as there would be no atmosphere to protect us from the sun’s deadly rays. In this huge ocean of air surrounding the earth, there is more energy than in all the coal, oil and gas we have on the earth. Electrical energy is collected in the atmosphere as water is collected and stored in a dam (大坝). The existence of electricity in the air has been known for centuries. Men have gazed in wonder at the bright patterns of lightening in storm clouds. But thorough (彻底的，深入的) study of electricity in the air was not possible until the development of radio. It is not widely known that ______.

Furthermore, during the summer there are few clouds in the sky to protect plans from the sun’ s ray. Another problem is the fact that there are frequently strong winds that drive small, sharp particles of sand into the plants,earing and damaging them. The most difficult probiem for all forms of plant life, however, is the fact that the entire annual rainfall occurs during a few days or weeks in spring. Grasses and flowers in desert survive from one year to the next by existing through the long, hot, dry season in the form of seeds. These seeds remain inactive unless the fight amount of’rain falls. If no rain falls, or if insufficient rain falls, they wait until the next year, or even still the next. Another factor that helps these plants to survive is the fact that their life cycles are short. By the time the water from the spring rains disappears — just a few weeks after it falls — such plants no longer need any. The perennials (多年生植物) have special features that enable them to survive as plants for several years. Thus, nearly all desert perennials have extensive root systems below ground and a small shoot system above ground. The large root network enables the plant to absorb as much water as possible in short time. The small shoot system, on the other hand, considerably limits water loss by evaporation. Another feature of many perennials is that after the rainy season they 10se their leaves in preparation for the long, dry season, just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation (蒸发) duing the dry season. Then, in next rainy season, they come fully alive once more, and grow new branches, leaves and flowers, just as the grasses and flowers in desert do. Desert perennials lose their leaves after the rainy season just as trees in wetter climates lose theirs in wetter climates because winter arrives, but the reasons for this features are different.
