Before we begin our nature walk today, Id like to give you a short history of our National Park Service. The National Park Service began

11、in the late 1800s. A small group of explorers had just completed a month-long exploration of the region that is now Yellowstone. They gathered around the campfire and after hours of discussion, they decided that they should not claim this land for themselves. They felt it should be accessible to eve

12、ryone. So they began a campaign to preserve this land for everyones enjoyment. Two years later, in the late 19th century, an act of Congress, signed by President Ulysses S- Grant, proclaimed the Yellowstone region a public park. It was the first national park in the world. After Yellowstone became a

13、 public park, many other areas of great scenic importance were set aside. And in 1916 the National Park Service was established to manage these parks. Today, there are more than 360 parks in the US National Park System and more than 3,600 areas under similar protection around the globe. National par

14、ks and other public lands shelter well over half of the plant and animal species in North America. And today more than 80 countries have also established several hundred similar reserves specifically to protect biological diversity. As a park ranger, I am an employee of the National Park Service. In

15、 the national park, park rangers are on duty at all times to answer questions and help visitors in any difficulty. Nature walks, guided tours and campfire talks are offered by specially trained staff members. The Park Service also protects the animals and nlants within the parksPassage 2 Plans to Cl

16、one Pandas to Save Them from ExtinctionJust over two years ago, China announced it was going to clone the giant panda, the countrys national symbol. Pandas are extremely endangered; there are only 1,000 left in the wild and a hundred in captivity. The move to begin cloning the animal was prompted by

17、 unsuccessful attempts to increase its population by using artificial insemination.Pandas are widely known for their feeble efforts when it comes to mating. Even in the wile where their sexual drive may be higher, the survival rate of the cubs is very low: more than half of them die shortly after bi

18、rth. Unusually, this summer six panda cubs were born in the Wolong Giant Panda Reserve in the southwest province of Sichuan, in China. However, zoologists were reluctant to join in the celebrations: it is widely held that the panda will become extinct within 10 years.In 1999, Dr. Chen Dayuan, from C

19、hinas Academy of Sciences, began a research program aimed at cloning a panda. He took the nucleus from the cell of an adult panda and inserted it into an egg from a rabbit which had had its nucleus removed, to produce a ball of cells that could become a panda embryo. So far this step has proven succ

20、essful. The difficulty will be growing a panda out of a collection of cells. Dayuan is currently looking for suitable surrogate mothers and is considering black and sloth bears as candidates. He hopes to have a panda cloned within the next five years.Not everyone in China is in favor of trying to cl

21、one the panda. One of the countrys leading panda experts, Dr. Pan Wenshi, has studied them in the wild for two decades. He believes that attempts to clone this rare animal will detract from efforts to preserve the species in the wild. He has also dismissed the widely accepted theory that the pandas

22、threatened extinction is due to its decline in fertility. He argues that the main reason the panda is an endangered species is that humans have destroyed a large part of their habitat. Passage III Indoor Air PollutionAir pollution is a serious problem in many countries. Cars, airplanes, factories an

23、d waste centers are commonly blamed for polluting the air. They release a large amount of tiny black particles into the air. Such pollution is a great threat to people. Scientific studies show that air in homes and other buildings can be seriously polluted. It may be more polluted than the outside,

24、even in the most industrialized cities. United States Environmental Protection Agency publishec a guide to indoor air quality. The guide says that most people spend about 90 percent of their time indoors. So, for many people, indoor air pollution may be a greater health risk than outdoor pollution.

25、Many new homes and office buildings contain a number of pollutants. Some release gases or particles into the air. They include different kinds of fuel, wood, building materials, office equipment, furniture, floor coverings and chemical cleaning products. Bacteria found in plants pets and central hea

26、ting or cooling systems also affect air quality. Reducing the amount of water in the air is one way to prevent the growth of bacteria and mold indoors. Chemical products also should be limited. Experts advise not to use products with strong chemical smells in closed places Buy small amounts of the c

27、hemicals and use them immediately. This will prevent the need to store such products. Health problems from indoor air pollution may be felt soon after entering a building. Immediate effects include a burning feeling in the eyes, nose and throat. People may develop headaches, lose their balance or fe

28、el extremely tired. Such effects generally last for a short time. Other health problems may develop over a longer period of time. These include lung disease, heart disease and cancer. Experts say the best way to improve indoor air quality is to remove materials that cause the air pollution. Another

29、way is to increase the amount of outside air that enters the building. And a third way is to use devices that clean the air.Part D Extensive Listening1.professional 2.shy 3.in public 4.old saying 5.group 6.middle 7.successful 8.overcome. 9.reminding 10.at a party 11.unlimited 12.weather 13. safe sub
