Oil and some chemicals and minerals already are taken from the sea. By using nuclear energy, ocean water can be turned into fresh water by removing the salt. Producing food from farms under the sea is a possibility in the future. Food grown in the sea could help solve the problem of many of the worlds people who go hungry every day. About ten to fifteen percent of the worlds people do not have enough food. Some scientists believe that some day the sea will be used to make electric power. This would help meet the need for more power for the worlds industries. The decreasing supply of coal, oil and gasoline shows that the need to and new kinds of power is urgent.Questions:1.

Some snakes live in warm, dry deserts, others live in green forests, field and wet land. Some never go far from water and are fine swimmers. Some live all their lives in the sea. Most snakes can swim. Because snakes are cold-blooded and depend on warm air for comfort and existence, the largest number of snakes are found in the hottest parts of the earth. Even so, many snakes stay away from the direct rays of the sun when possible. In places where it freezes, snakes often hide themselves far under the ground or in caves and stay there until spring. Snakes are smart enough to stay alive. They are smart enough to find food and kill their enemies. But compared with other animals, they are believed to be below average in intelligence.Questions : 6. Where can snakes never be found?7. What characteristics do most snakes have?8. Why do a large number of snakes live in hot regions?9. How do snakes keep alive in cold areas?10.

The bicycle is a popular means of transportation in China. With the improvement of living standard, there has been a tendency for people to turn to motorcycles. There is no doubt that the motorcycle has its own advantages. However, in my opinion, we should encourage people to keep on riding bicycles. First, bicycles cause little pollution to the environment. Since a bicycle is much quieter than a motorcycle, it doesnt cause noise pollution. Moreover a bicycle never sends out harmful gas into the air. Second, either in the process of making bicycle or using them, they consume much less energy than motorcycles. Since energy resources are limited and most of them are not renewable, it is necessary to conserve them. Therefore, it is reasonable to call for riding bicycles. Third, riding bicycles does good to our health. It is an economical and effective method available to do physical training. Riding bicycles can build our body and keep us fit. Due to the reasons mentioned above, it can be concluded that riding bicycles is really good for an individual as well as the whole society. So why not call for the riding of bicycles? 课文参考译文 Practical reading 绿色电力 今天，大众杂志所公布的最新一份开拓性的研究报告表明，在加尼福利亚州新近放开的公用事业市场上所销售的“绿色”电力，对消费者来讲很大程度上是一个骗局，而且对环境的益处也微乎其微，甚至根本没有。 大众杂志总裁琼克莱布鲁克说：“电力事业部门正在为撤消管制而辩解，声
