Passage Four

　　How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs?

　　These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage.

　　For a long time, people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.

　　Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount if garbage piling up on the earth.

　　13. What two problems can man solve by burning garbage?

　　A. The shortage of energy and air pollution.

　　B. The shortage of energy and the land to hold garbage.

　　C. Air pollution and the shortage of fossil fuel.

　　D. Air pollution and the shortage of land to hold garbage.

　　14. According to the passage, using garbage is ______.

　　A. for heating in France each year

　　B. a new way in a modern society

　　C. a good way to solve the problem of energy shortage

　　D. too expensive as an energy source

　　15. What is the author's attitude?

　　A. Delighted. B. Sad. C. Agreeing. D. Disagreeing.

　　16. The best title for the passage may be ______.

　　A. Garbage and the Earth B. Fossil Fuel and Garbage

　　C. Land and Garbage D. Garbage? Energy Source

　　Passage Five

　　In 1924, Nordic ski events were held at the first Winter Olympics in Chamonix, France. But the American skiers came home without medals. Norway took most of the medals for cross-country and ski jumping events that year. They did the same for many years after. From 1924 through 1972, the American skiers had no medals to show for their Olympic trips. The U.S. was generally thought to be weak in ski competition.

　　But in 1974 it was discovered that the U. S. record was slightly better than people had been led to believe. And Norway's record was not quite as good. The discovery was a surprise and a delight to American ski fans, but even more so to American skier Anders Haugen. After fifty years, Anders got the medal he should have won back in 1924.

　　In the ski jump event at Chamonix in 1924, Haugen had scored in fourth place. He had just missed earning a medal. His score was 17.916, just slightly behind Thorleif Haug of Norway. Haug's score of 18 had won him the bronze medal.

　　But in 1974, Norway's National Olympic Committee did a check of all final Olympic results. There had been an error in computing Haug's score! So Haugen, now, an elderly man, traveled across the ocean for his award. On September 12,1974, he was given a bronze medal in a special ceremony at the Norway Ski Museum.

　　A. the 1924 Olympics B. Norway's Skiers

　　C. An Olympic Record Corrected D. American Skiers in the Olympics

　　19. The writer says "the discovery was a surprise and a delight to American ski fans" in order to ______.

　　A. show that the error and its correction were important to ski fans as well as to Haugen

　　B. show that the error was more important to fans than to Haugen

　　C. suggest that the Americans eared more about the error than the Norwegians
