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 homes.
Zoo claims to educate people and save endangered species, but visitors leaves zoos without having learned anything meaningful about the animals’ natural behaviour, intelligence, or beauty. Zoo keeps animals in small spaces or cages, and most signs only mention the species’ name, diet, and natural range. 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 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 (圈养繁殖) of endangered big cats, Asian elephants, and another 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 still 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.How would the author describe the animals’ life in Zoos?
| A．Dangerous | B．Unhappy | C．Natural | D．Easy |

Paricutin was born in Mexico in February, 1943. At that time, Paricutin was 500 feet high, and it is now over 9,000 feet high. Today Paricutin is asleep.
What is Paricutin? It was the first volcano (火山) in the world which was seen from its birth right up to the present day. On February 20, 1943, a peasant and his wife set out to work in their corn fields from the Mexican village of Paricutin. They were surprised to find the earth warm under their feet. Suddenly they heard noise deep in the earth and a small hole appeared in their field. In the afternoon there was a sudden loud noise and stones were thrown high in the air. The peasants ran from the field and turned to watch. They saw the birth of a volcano.
Large quantities of stone and lava broke out and a little hill began to form. By evening this hill was 100 feet high and hot ashes (灰烬) were falling on the village. At night the strong light of the hot lava lit up the countryside. The trees near the village were killed and the villagers had to leave their houses. When the villag
e was destroyed, its name was given to the volcano. The news quickly reached Mexico City, far to the east. Many people came to watch the scene. The volcano grew and grew for ten years and hundreds of square miles of forests were destroyed. Then Paricutin went to sleep..

You might think that “global warming” means nothing more than a rise in the world’s temperature. But rising sea levels caused by it have resulted in the first evacuation of an island nation. The citizens of Tuvalu will have to leave their homeland.
During the 20th century, sea level rose 8~12 inches. As a result, Tuvalu has experienced lowland flooding of salt water that has polluted the country’s drinking water.
Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions（导致温室效应的气体排放）,which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years.” Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.
Tuvalu is not the only country that is vulnerable （易受影响的）to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.. The text is mainly about_________.
| A．rapid changes in earth’s temperature |
| B．bad effects of global warming |
| C．moving of a country to a new place |
| D．reasons for lowland flooding |
.. What is the probable meaning of the underlined word in the first paragraph?

. According to scientists, the DIRECT cause of more and fiercer storms is_________.
| A．greenhouse gas emissions in industrialized nations |
| B．continuous global warming |
| C．higher surface water temperatures of the sea |

. Laupepa was not satisfied with the United States be
cause it did not_________.
| A．believe the problems facing Tuvalu were real |
| B．sign an agreement with Tuvalu |
| C．allow Tuvaluans to move to the US |
| D．agree to reduce its greenhouse gas emissions |
. The country whose situation is similar to that of Tuvalu is_________.
| A．Australia |
| B．New Zealand |
C．the Unit ed States |

Twenty-fiv
e years ago if you made a trip to the local library and searched for articles on globing warming, you’d probably come up with a few from the leading magazines in the world. As an Internet search on global warming now shows, the subject has become as rooted in people’s mind as Madonna or microwave cooking.
With the possible exception of another world war, a giant planet, or an incurable disease, global warming may be the largest danger to our planet. For decades human factories and cars have sent billions of tons of greenhouse gases into the atmosphere, and the climate has begun to show some signs of warming. If steps are not taken soon to reduce the amount of carbon dioxide sent into the atmosphere, the result could terribly affect human life. We have already seen growing destruction, such as drought and death in Sudan, flooding in Asia, bush fires in Indonesia, and fierce winter storms in central Europe.
The Republic of Maldives is barely above sea level. Its 250, 000 citizens are scattered across 1,200 islands in the Indian Ocean. A strong typhoon could spell the end for the entire country, as sea levels could continue rising. The entire population would have to be moved away as the country disappears under the sea.
The greenhouse effect is a naturally occurring phenomenon that keeps our planet at a comfortable temperature averaging 60°F. Since the mid-nineteenth century, however, carbon dioxide in the atmosp
here has increased nearly 30% because of the increased use of fossil fuels to run cars, heat homes and power factories. Without controlling, the amount of carbon-dioxide by 2100 may increase by 30%-150% and could lift the average global temperature by up to 2.5° F the next 50 years. .

The world itself is becoming much smaller by using modern traffic and modern communication means （通讯设备）.Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, Man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air.
Pollution by carbon dioxide is now the most dangerous kind of air pollution. It is caused by heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time..

People have smoked cigarettes for a long time now. The tobacc
o which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe . In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person’s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy(头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers’ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases. .
