单选题{{B}}Passage 2{{/B}} 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 some time it can save the land to hold garbage. For a long time, people buried garbage or dumped(倾倒) it on empty land．Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fu el to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil(化石) 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. (78) {{U}}The heat that is produced by burning garbage is used to boil water. {{/U}}The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants bum 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 mil lion barrels of oil. Our fossil fuel supplies are limited．(79) {{U}}Burning garbage might be one kind of energy source that we can use to help meet our energy needs. {{/U}}This method could also reduce the amount of garbage piling up on the earth.

单选题When we accept the evidence of our unaided eyes and describe the Sun as a yellow star, we have summed up the most important single fact about it--at this moment in time. It appears probable, however, that sunlight will be the color we know for only a negligibly (微不足道) small part of the Sun's history. Stars, like individuals, age and change. As we look out into space, we see around us stars at all stages of evolution.There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit; there are scaring ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range. Obviously, the "daylight" produced by any star depends on its temperature; today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun's light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves. That yellow "hump" will shift as the Sun evolves,and the light of the day will change accordingly. It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel--which it is now doing at the spanking rate of half a billion tons a second--it will become steadily colder and redder.

单选题When we want to 1 other people what we think, we can do it not only with the help of words, but also in many 2 ways. For example, we sometimes move our heads 3 when we want to say "yes", and we move our heads 4 when we want to say "no". People who can 5 speak talk to each other with the help of their fingers. People who do not understand each other"s language have to do the same. The following story shows 6 they sometimes do it. 7 English man who could not speak Italian was 8 travelling in Italy. One day he entered a restaurant and sat 9 a table. When the waiter came, the Englishman opened his mouth, 10 his fingers into it, 11 them out again and moved his lip. In this way he meant to say," 12 me something to eat." The waiter soon brought him 13 tea. The Englishman 14 his head and the waiter understood that he didn"t want tea, so he took it 15 and brought him 16 coffee. The Englishman was angry. He was just going to leave the restaurant 17 another traveler came in. When this man saw the waiter, he 18 his hands on his stomach. That was enough. In 19 minutes there was a large plate of bread and meat 20 his table.

单选题How could we possibly think that keeping animals in cages in unnatural environments—mostly for entertainment purposes—is fair and respectful? Zoo officials say they are concerned about animals. However, most zoos remain "collections" of interesting "things" rather than protective habitats. Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural zones. Zoos claim to educate people and save endangered species, but visitors leave zoos without having learned anything meaningful about the animals' natural behavior, intelligence, or beauty. Zoos keep animals in small spaces or cages, and most signs only mention the species' names, diets, and natural ranges. The animals' normal behavior is seldom noticed because zoos don't usually take care of the animals' natural needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise. This results in unusual and self-destructive behavior called zoochosis. A worldwide study of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain. Furthermore, most animals in zoos are not endangered. Captive breeding of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out. In fact, baby animals also attract a lot of paying customers. Haven't we seen enough competitions to name baby animals? Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them. Instead of supporting zoos, we should support groups that work to protect animals' natural habitats.
