单选题. There is a measurable relation between how much a person learns and his attitude toward the subject to be learned. When faced with a difficult learning task, one path to success is to concentrate on the positive aspects of the subject matter. If a student has a boring teacher, one solution is to look for the positive aspects of completing the course, regardless of how boring the teacher happens to be. To accomplish this might require a private tutor or some independent reading, but with the right attitude, success is possible. Over-achievers—students who do better than their test scores show—usually have a positive interest in learning. They may learn some things more slowly, and they may make more efforts, but, to compensate (补偿), they are often better at applying what they have learned. As long as they do not have emotional problems, they are successful. Under-achievers—those who function below their ability shown by test scores—often tend to allow a few negative factors to affect them. Because of their negative attitudes, they sometimes become unfairly critical of teachers. They allow themselves to get bored when it is not necessary. In short, their attitudes often cause them to learn less than over-achievers. If you learn to replace a negative attitude toward learning with something more positive, you are on the road to achieving almost any goal you desire. For example, if you realize a personal computer with a word processor would improve your performance, but have an attitude that keeps telling you that a computer is difficult to operate, you tend to make all kinds of excuses. In short, you resist making full use of a terrific tool, simply because your negative attitude prevents you from learning.1.

单选题. People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country. On the average, we throw away more trash and garbage than the year before. The burning of garbage leads to air pollution. Many major industries are also the cause of the dirty air in and around the cities. The fumes from iron, steel, chemical, and petroleum production add particles(粉尘) to the air. The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches or loss of clear sight. Wherever coal and oil are used for fuel, fumes may kill trees and plants. In some of the larger cities, these fumes endanger the lives of human beings by leading to lung diseases and causing early death.1. From the passage, we know that ______.
