听力题 Finally there is one more element to business success that we haven''t talked about. I know what you think I''m going to say, luck and you''re partially right. Good entrepreneurs know how to make their own luck and that means being in the right place at the right time with the right product. Let me give you a little example, early in this century, if you’re a traveler by train and subway and you happen to get a little thirsty in the station, where would you go for some water? There were no big soda machine at every corner or even drinking fountains, yet there were thousands of thirsty travelers out there, well, what they did was drank water out of one little tin cup that was passed from one thirsty commuter to the next. That''s right, everybody drank out of the same cup, and you can bat it didn’t get washed after every user. Will, that was the right time for the right product and there was a man who had it. His name is H M and his product was the disposable paper cup. He came up with it just as the nation was becoming concerned about their health risks associated with the tin cups. Laws were passed outlying the things; reports were published showing just what sorts of germs can be passed around from sharing them. Mr. M road that way to become the best known producers of one of the most successful paper products of all time. He originally called his product health cups, but later changed the nature, so can anyone guess what that name might be?

听力题 Human population near the equator have evolved dark skin over many generations because of exposure to the fiercest rays of the sun. A similar phenomenon has also occurred in other parts of the animal kingdom. The African grass mouse is a good example. Most mice are nocturnal, but the African grass mouse is active during daylight hours. This means that it spends its days searching for food in the semi-dry bush in squired habitats of eastern and southern Africa. Its furry stripe''s like a chipmunk''s, which helps it blend in with its environment. Because it spends a lot of time in the intense tropical sun, the grass mouse has also evolved two separate safeguards against the sun''s ultraviolet radiation. First, like the population of humans in this region of the world, the skin of the grass mouse contains lots of melanin, or dark pigment. Second and quite unusual, this mouse has a layer of melanin pigmented tissue between its skull and skin. This unique cap provides an extra measure of protection for the grass mouse and three other types of African mouse, like rodents that are active during the day. The only other species scientists have identified with the same sort of skull of that occasion is the white camp-making bat of the Central American tropic. Although these bats sleep during the day, they do so curled up with their head exposed to the sun.

听力题Today most astronomers accept the notion that groups of stars that make up the universe are all moving farther and farther away from each other. but until very recently this idea of an expanding universe was not a theory most European scholars believed in since ancient times and up to about the17th century most of these scholars thought the size of the universe have remained unchanged since the moment of its creation or perhaps forever, with all the stars remaining more or less in place in relation to each other. but that was challenged in the late 17th century by Izic Newton''s idea of gravity as a force of attraction, which contradicted the idea of a university that is static, unchanging. If gravity causes all the stars out there in space to attract each other as Newton said, then they could remain motionless. Sooner or later all the stars will fall in absorb each other. well, scientists then propose a new model, taking Newton''s theory into account, they didn''t want to abandon the idea of motionless stars, but for this model to work, so the stars won''t fall in each other, they had to modify Newton''s law of gravity, so they theorize that for distance as large as those between stars, the gravitation force repels rather attracts. As you might guess, this other contradictions. But this is prettily resolved in the past centuries by currently accepted theory, which says the universe is continuously expanding. You''ll be reading all about that as your homework tonight.

But you''ll realize that unless you have a car, Bundy is at least at 25 minutes walk from the center of campus. And don''t count on taking the campus bus, it runs at really inconvenient time. M: Great way to start your college career. But, I don''t know, maybe there is a positive side of all these. Since we''ll be so far away from everything, we''ll be forced to use our time wisely. W: True. I''ve heard lots of first year students get into trouble because they hang out every day in the student center till it closes. M: Exactly! And not only that, we will get plenty of exercise from all that extra walking. W: Yeah. And that is not exactly easy walking either. Around here you just about need a pair of hiking boots, and to enjoy mountain climbing. M: You count to get avoid there. But at least there are great vistas from some of the buildings, not to mention the possibility of some serious sled riding when it snows. M: I see you still got all your suitcases with you too.

听力题This is our last meeting before the camps arrive tomorrow. I''ll give u the activity schedule later. But, now I want to answer a question one of u asked me yesterday about camps with asthma. Let me explain a little about the disease. First of all, it''s chronical and very common. 20 million people in the United States alone have it. It affects the bronchial tubes that are the airways of the lungs. During normal breathing, air is drawn in through the mouse and nose, and eventually makes its way into the bronchial tubes. The asthma patient''s bronchial tubes are very sensitive, and easily irritated by exercises or strength, exposure to allergy or pollution, or breathing in cold air, cigarettes smoke. When asthmatic suffers an attack, the airway path was constricted, making it difficult for the person from breathing normally. If a camp in your group has even a mild asthma, you would be informed and given further instruction about what to do in case of an attack. But don''t worry. Some of our camps might have a mild case, but they always bring their medicines with them and we never have a problem. Are there any other questions? Ok, let''s talk about the schedule for tomorrow.

听力题One important thing about art movements is that their popularity can be affected by social conditions, which are themselves often affected by historical events. As an example, look at what happened in the United States early in the 20th century, around the time of the great depression, the art movement known as the Regionalism had begun in the United States even before the depression occurred. But it really flourished in the 1930s, during the depression years. Why? Well, many artists who had been living in big cities were forced by the economic crisis to leave those big cities and move back to their small towns in rural America. Some of these artists came to truly embrace the life in small towns and to eject city life in so called “sophisticated society”. These artists or specifically certain painters really built regionalist movement. They created things in every day life in small towns or farming areas. And their style was not all-neutral, really big glorified or romanticized country life, showing it stable, wholesome, and embodying important American traditions. And this style became very popular, in part because of the economic conditions of the time. You see, the Depression had caused many Americans to begin to doubt their society. But regionalism artists painted scenes that glorified American values, scenes that many Americans could easily identify with. So the movement helped strengthen people’s faith in their country, faith that had weakened as the result of the depression. But in the 1940s, before and after the Second World War, American culture began to take on a much more international spirit, and Regionalism, with its focus on small town life, well, it lost a lot of popularity, as American society changed once again.
