单选题Snow Ranger The two things—snow and mountains—which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called "White Death." It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937-38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area. Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber. He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better. He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area's operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.

单选题Animal"s "Sixth Sense" A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, 1 , seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for 2 , experts said. Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island"s coast clearly 3 wild beasts, with no dead animals found. "No elephants are dead, not 4 a dead rabbit. I think animals can 5 disaster. They have a sixth sense. They know when firings are happening," H. D. Ratnayake, deputy director of Sri Lanka"s Wildlife Department, said about one month after the tsunami attack. The 6 washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka"s biggest wildlife 7 and home to hundreds of wild elephants and several leopards. "There has been a lot of apparent evidence about dogs barking or birds migrating 8 volcanic eruptions or earthquakes. But it has not been proven, "said Matthew van Lierop, an animal behavior 9 at Johannesburg Zoo. "There have been no 10 studies because you can"t really test it in a lab or field setting, "he told Reuters. Other authorities concurred with this 11 . "Wildlife seem to be able to pick up certain 12 , especially birds...there are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife. Animals certainly 13 on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense"—or 14 other mythical power—is an enduring one which the evidence on Sri Lanka"s ravaged coast is likely to add to. The Romans saw owls 15 omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.

单选题{{B}}第二篇{{/B}} On Being a Matchmaker The first thing I do when I wake up is to make a mental list of all things I have to do that day. I'm very organized! Then I get up and have my bath. Often my best matchmaking(媒人) ideas come while I'm in the bath. Sometimes I have a really good idea about who might be good with whom. Before I did matchmaking , I was a social worker, but I knew I wanted to do something without bosses telling me what to do and that I am good at dealing with people. Also I had seen too many broken marriages and too many people go downhill because they were so lonely. So I gave up my job, did a bit of research and started the matchmaking business in 1970. Over the last few years we've been doing introductions throughout Europe as well as here in Britain. Europeans want to meet British people. For every 100 people who come to us, about 65 will settle down. We keep going until clients (委托人) find someone that they get on very well with. We're great triers. Of course there are impossible people, those who will never settle... Sometimes I end up giving advice to clients. A few months ago, we had a highly paid scientist with a very nice face, but every woman refused to meet him a second time. It soon became clear that he did not like changing his shirts. So I had to be very honest and frank and told him, "But a woman can't start to love you if your shirt smells. " The job is most satisfying when I get a call from a couple telling me they have fallen in love.

单选题Long Bus Rides Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard (广告牌) goes by outside the bus window. "Buy Super Clean Toothpaste." "Drink Good"n Wet Root Beer." "Fill up With Pacific Gas." Only if you sleep, which is equal to turning the television set off, are you free from the unending cry of "You Need It! Buy It Now!" The beginning of the ride is comfortable and somewhat exciting, even if you"ve traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it"s fun to try to figure it out the first hour or so. If the driver is particularly reckless (鲁莽的) or daring, the ride can be as thrilling as a suspense (悬疑) story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you"ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there"s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you"ve sat with your legs crossed, with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.

单选题Computers Before the widespread use of computers, managers could not make full use of large amounts of valuable information about a company's activities. The information either reached managers too late or was too expensive to be used. Today, managers are facing a wide range of data processing and information instruments. In place of a few financial controls, managers can draw on computer-based information systems to control activities in every area of their company. On any kinds of performance measures, the information provided by these systems helps managers compare standards with actual results, find out problems, and take corrective action before it is too late to make changes. The introduction of computerized information systems has sharply changed management control in many companies. Even a neighborhood shopkeeper may now use computers to control sales, billing, and other activities. In large companies, electronic data processing systems monitor entire projects and sets of operations. Now, there are about 24 million microcomputers in use in the United States—one for every 10 citizens. It is estimated that by 1996, 61 percent of American managers will be using some sort of electronic work station. In order for managers to be sure that the computer-based information they are receiving is accurate, they need to understand how computers work. However, in most cases they do not need to learn how to program computers. Rather, managers should understand how computerized information systems work; how they are developed; their limitations and costs; and the manner in which information systems may be used. Such an understanding is not difficult to achieve. One research found that business firms were more successful in teaching basic information about computers to business graduates than they were in teaching business subjects to computer science graduates.
