Like Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record for a low temperature reading—125 Fahrenheit below zero. Readings of 85 degrees below zero are common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter is about 73 degrees below zero. One thing alone makes it almost impossible for men to Jive in Antarctica and in parts of the Arctic. This one thing is the low temperature—the killing chili of the far North and the polar South. To survive, men must wear the warmest possible clothing. They must build windproof shelters. They must keep heaters going at all times. Not even for moment can they be unprotected against the below-zero temperature. Men have a way of providing for themselves. Polar explorers wrap themselves in warm coats and furs. The cold makes life difficult. But the explorers can stay alive. What about animals? Can they survive? Do we find plants? Do we find life in the Arctic and the Antarctica? Yes, we do. There is life in the oceans. There is life on land. Antarctica, as we have seen, is a cold place indeed. But this has not always been the case. Expedition scientists have discovered that Antarctica may have been much like our own. Explores have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests. Heat and moisture must have kept the trees in the forests alive.

A succession of three of four maps presents a continuous picture of weather changes. Weather forecasts are able to determine the speed of air masses and fronts; to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time. All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day "outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlo6ks are based upon an analysis of the upper air levels with often Set the stage for the development of air masses, fronts, and storms. Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weather modification studies. But the limitations of weather modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographical precipitation on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.

单选题 The National Trust The National Trust in Britain plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the Government, it is not a rich Government department. It is a voluntary association of people who care for the unspoiled countryside and historic buildings of Britain. It is charity which depends for its existence on voluntary support from members of the public. Its primary duty is to protect places of great natural beauty and places of historical interest. The attention of the public was first drawn to the dangers threatening the great old houses and castles of Britain by the death of Lord Lothian, who left his great seventeenth- century house to the Trust together with the 4,500-acre park and estate surrounding it. This gift attracted wide publicity and started the Trust's "Country House Scheme". Under this scheme, with the help of the Government and the general public, the Trust has been able to save and make accessible to the public about one hundred and fifty of these old houses. Last year about one and three quarters of a million people paid to visit these historic houses, usually at a very small charge. In addition to country houses and open spaces, the Trust now owns some examples of ancient wind and water mills, nature reserves, five hundred and forty farms and nearly two thousand five hundred cottages or small village houses, as well as some complete villages. In these villages no one is allowed to build, develop or disturb the old village environment in any way and all the houses are maintained in their original sixteenth-century style. Over four hundred thousand acres of coastline, woodland, and hill country are protected by the Trust and no development or disturbances of any kind are permitted. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife. So it is that over the past eighty years the Trust has become a big and important organization and an essential and respected part of national life, preserving all that is of great natural beauty and of historical significance not only for future generations of Britons but also for the millions of tourists who each year invade Britain in search of a great historic and cultural heritage.

You may not see them for years at a time, but just knowing they're out there makes you feel better. Hearing the names of these famous old friends--Yosemite, Yellowstone, Grand Canyon--revives memories of visits past and promotes dreams of those still to come. From Acadia to Zion, 369 national parks are part of a continually evolving system. Ancient fossil beds, Revolutionary War battlefields, magnificent mountain ranges, and monuments to heroic men and women who molded this country are all a part of our National Park System (NPS). The cafe and preservation for future generations of these special places is entrusted to the National Park Service. Uniformed Rangers, the most visible representatives of the Service, not only offer park visitors a friendly wave, a helpful answer, or a thought-provoking history lesson, but also are skilled rescuers, firefighters, and dedicated resource protection professionals. The National Park Service ranks also include architects, historians, archaeologists, biologists, and a host of other experts who preserve and protect everything from George Washington's teeth to Thomas Edison's wax recordings. Modern society has brought the National Park Service both massive challenges and enormous opportunities. Satellite and computer technologies are expanding the educational possibilities of a national park beyond its physical boundaries. Cities struggling to revive their urban cores are turning to the Park Service for expert assistance to preserve their cultural heritage, create pocket parks and green spaces, and re-energize local economies: Growing communities thirsty for recreational outlets are also working with the NPS to turn abandoned railroad tracks into bike and hiking trails, as well as giving unused federal property new life as recreation centers. To help meet these challenges and take advantage of these opportunities, the National Park Service has formed partnerships--some dating back 100 years, some only months old--with other agencies, state and local governments, corporations, American Indian tribes and Alaska Natives, Park Friends groups, cooperating associations, private organizations, community groups and individuals who share the National Park ethic. National Park Week 1996 is a celebration of these partnerships.

单选题African wild dog Finding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent's most endangered carnivores (食肉动物), it's a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young. The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to 5,000 animals remain, and the species is expected to go extinct within decades if the trend continues. Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog's weakness lies in its social organization. Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores. Because pups can't keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there. Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack. Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often. A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack." And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustainable threshold. Mammal ecologist Chris Carbone at London's Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vital in preserving the species, he says.

单选题Oseola MeCarty Late one Sunday afternoon in September 1999, Oseola McCarty, an elderly cleaning lady passed away in the little wooden flame house where she had lived and worked for most of her life. It may seem like an ordinary end to a humble life, but there was something quite exceptional about this woman. In the summer of 1995, McCarty gave $150, 000, most of the money she had saved throughout her life, to the University of Southern Mississippi in her hometown. The money was to help other African Americans through university. She had started her savings habit as a young child when she would return from school to clean and iron for money which she would then save. She led a simple, frugal existence, never spending on anything but her most basic needs. Her bank also advised her on investing her hard-earned savings. When she retired, she decided that she wanted to use the money to give children of limited means the opportunity to go to university. She had wanted to become a nurse, but had to leave school to look after ill relatives and work. When asked why she had given her life savings away, she replied, "I"m giving it away so that children won"t have to work so hard, like I did." After news of her donation hit the media, over 600 donations were made to the scholarship fund. One was given by media executive, Ted Turner, who reputedly gave a billion dollars. She didn"t want any fuss made over her gift, but the news got out and she was invited all over the United States to talk to people. Wherever she went, people would come up to her to say a few words or to just touch her. She met the ordinary and the famous, President Clinton included. In the last few years of her life, before she died of cancer, McCarty was given over 300 awards: she was honoured by the United Nations and received the Presidential Citizen"s Medal. Despite having no real education, she found herself with two honorary doctorates: one from the University of Southern Mississippi and the other from Harvard University. Her generosity was clearly an inspiration to many and proof that true selflessness does exist.
