单选题Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfasts. The results show that if a person eats a breakfast, be or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he will learn more quickly and listen more carefully in class. The result (效果，答案) is opposite (相反) to what some people think. Having no breakfast will not help you lose weight (减轻体重). This is because people become so hungry at noon that they eat too much for lunch. They will gain (获得，利润) weight (增加体重) instead of losing it. You will lose more weight (重量，负担) if you reduce your other meals.

单选题All living things need air to live. People need clean air to breathe. But sometimes people make the air dirty. They drive so many cars that the fumes from the cars pollute the air. Fumes are made when gasoline is burned. The fumes that come out of cars, buses and trucks can pollute the air. Environmental engineers are people who work to protect the environment. One of their jobs is to design or plan cars that will not pollute the air. Some time ago environmental engineers designed an object for cars that removes harmful pollution. Now cars are causing less pollution than they once did, because environmental engineers worked hard to protect the environment.
