1、How to Be a Successful Business personHave you ever wondered why some people are successful in business and others are not? Here\'s a story about one successful business person. He started out washing dishes and today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.While Mr. Kazi was working at the car rental (租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as a cook\'s assistant. His job was to clean the kitchen and help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside and the food was terrible. Mr. Kazi borrowed money from a bank and bought the restaurant. For the first six months, Mr. Kazi worked in the restaurant from 8 A.m. to 10 p. m., seven days a week. He and his wife cleaned up the restaurant, remodeled the front of the building, and improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit, too.Today Mr. Kazi owns 168 restaurants, but he isn\'t planning to stop there. He\'s looking for more poorly managed restaurants to buy. "I love it when I go to buy a restaurant and find it\'s a mess," Mr. Kazi says. "The only way it can go is up."Mr. Kazi became the manager of a new restaurant because ____.【单选题】

2、African wild dogFinding 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 to5,000 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 sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The African wild dog has been endangered.【单选题】

3、Britain\'s Solo SailorEllen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money for three years to buy her first small sailing boat. When she was 18, she sailed alone around Britain and won the "Young Sailor of the Year" award.Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors and she was given a very warm welcome when she returned.Ambition and determination have always been a big part of Ellen\'s personality. When she was younger, she lived in a kind of hut (棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race. Then she took a one - way ticket to France, bought a tiny seven meter Class Mini yacht (游艇), slept under it while she was repairing it, and then she raced it 4,000 kilometres across the Atlantic in 1997, alone for 33 days.Ellen has to learn many things, because sailing single - handed means that she has to be her own captain, electrician, sailmaker, engineer, doctor, journalist, cameraman and cooker, She also has to be very fit, and because of the dangers of sleeping for long periods of time she\'s in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time.And she needs courage. Once, in the middle of the ocean, she had to climb the mast (桅杆) of a boat to repair the sails at four o\'clock in the morning, with 100 kph winds blowing around her. It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It\'s hard to describe how it feels to be up there. It\'s like trying to hold onto a big pole, which for me is just too big to get my arms around, with someone kicking you all the time and trying to shake you off".But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean and having the chance to live this. I just feel lucky to be here."The word "solo" in the title could be best replaced by ____. 【单选题】

A.single - handed

B.self - made

C.one performer

D.self - starter

正确答案:A

答案解析:本题是词义题，难度不大，考查的是基本意义，不需要查询引申意义。此外，文中第四段开头，because sailing single - handed means ……“Ellen必须学会许多事情，因为单独航行意味着……”A复制了文章原话，是答案。

4、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting _____ about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.invention

B.theory

C.paper

D.experiment

正确答案:B

答案解析:本段第2句说，Bose没有办法使其他的科学家believe his theory，所以第1句的studying an mterestmg之后缺失的词应该是theory。

5、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, ____ that other countries can be found ready to accept its manufactures.【单选题】
