1、旧托福parte听力稿I-Ol-l(man) Community service is an important component of education here at our university. We encourage all students to volunteer for at least one community activity before they graduate. A new community program called One On One helps elementary students whove fallen behind .You educat

2、ion majors might be especially interested in because it offers the opportunity to do some teaching -that is, tutoring in math and English.Youd have to volunteer two hours a week for one semester. You can choose to help a child with math, English, or both. Half-hour lessons are fine, so you could do

3、a half hour of each subject two days a week.Professor Dodge will act as a mentor to the tutors-hell be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tuto

4、ring next week.Im sure youll enjoy this community service. and youll gain valuable experience at the same time. It looks good on your resume； too-showing that youve had experience with children and that you care about your community. If youd like to sign up, or if you have any questions, stop by Pro

5、fession Dodges office this week.1-01-2(woman) I hope youve all finished reading the assigned chapter on insurance-so that youre prepared for our discussion today. But, before we start, Id like to mention a few things your text doesnt go into.Its interesting to note that insurance has existed in some

6、 form for a very long time. The earliest insurance policies were called bottom contracts. They provided shipping protection for merchants as far back as 3000 B.C.In general, the contracts were often no more than verbal agreements. They granted loans to merchants with the understanding than if a part

7、icular shipment of goods was lost at sea, the loan didnt have to be repaid. Interest on the loans varied according to how risky it was to transport the goods. During periods of heavy piracy at sea, for example, the amount of interest and the cost of the policy went up considerably.So, you can see ho

8、w insurance helped encourage international trade. Even the most cautious merchants became willing to risk shipping their goods over long distances-not to mention in hazardous weather conditions-when they had this kind of protection available.Generally speaking, the basic form of an insurance policy

9、has been pretty much the same since the Middle Ages. There are four points that were salient then and remain paramount in all policies today. There were outlined in chapter six and will serve as the basis for the rest of the of todays discussion. Can anyone tell me what one of those points might be?

10、I-01-3(man) Located at the NASA Research Center in Iowa is a 5,000-gallon vat of water, and inside the tank is an underwater treadmill designed by Dava Newman, an aerospace engineer. For four years Newman observed scuba divers as they simulated walking on the Moon and on Mars on her underwater movin

11、g belt. She wanted to discover how the gravity of the Moon and of Mars would affect human movement.To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill. These weights were carefully adjusted so that the divers could experience underwater the gr

12、avity of the Moon and of Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the Moon. The Moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian gravit

13、y, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers took longer, graceful strides until they comfortably settled into an even quicker pace. Newman also noted that at Martian gra

14、vity, the divers needed less oxygen.The data Newman collected will help in the future design of Martian space suits. Compared to lunar space suits, Martian space suits will require smaller air tanks； and, to allow for freer movement, the elbow and knee areas of the space suits will also be altered.1

15、-02-1(man) Welcome to Everglades National Par. The Everglades is a watery plain covered with saw grass thats home to numerous species of plants and wildlife. At one and a half million acres, its too big to see it all today, but this tour will offer you a good sampling. Our tour bus will stop first a

16、t Taylor Slough. This is a good place to start because its home to many of the plants and animals typically associated with the Everglades. Youll see many exotic birds and, of course, our world famous alligators. Dont worry, theres a boardwalk that goes across the marsh so you can look down at the a

17、nimals in the water from a safe distance. The boardwalk is high enough to give you a great view of the saw grass prairie. From there well head to some other marshy and even jungle - like areas that feature wonderful tropical plant life.For those of you whod like a closer view of the saw grass prairi

18、e, you might consider renting a canoe sometime during your visit here. However, dont do this unless you have a very good sense of direction and can negotiate your way through tall grass. Wed hate to have to come looking for you.You have the good fortune of being here in the winter-the best time of y

19、ear to visit. During the spring and summer the mosquitoes will just about eat you alive! Right now theyre not so bothersome, but youll still want to use an insect repellent.I-02-2(woman) Thank you. Its great to see so many of you interested in this series on Survival in Outer Space. Please excuse th

20、e cameras - were being videotaped for the local TV stations.Tonight Im going to talk about the most basic aspect of survival - the space suit. When most of you imagine an astronaut, thats probably the fist thing that comes to mind, right? Well, without spaces suits, it would not be possible for us t

21、o survive in space. For example, outer space is a vacuum -theres no gravity or air pressure； without protection, a body would explode. Whats more, wed cook in the sun or freeze in the shade - with temperatures ranging from a toasty 300 degrees above to a cool 300 degrees below zero Fahrenheit.The sp

22、ace suit that NASA has developed is truly a marvel. This photo enlargement here is a life-size image of an actual space suit worn by astronauts on the last space shuttle mission. This past is the torso - its made of seven extremely durable layers. This thick insulation protects against temperature e

23、xtremes and radiation. Next is what they call a bladder of oxygen - thats an inflatable sac, filled with oxygen, to simulate atmospheric pressure. This bladder presses against the body with the same force as the Earths atmosphere at sea level. The innermost layers provide liquid cooling and ventilat

24、ion. Despite all the layers, the suit is flexible, allowing free movement so we can work.Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?I-02-3(woman) Good evening. My name is Pam Jones, and on behalf of

25、the Modem Dance club, Id like to welcome you to tonights program. The club is pleased to present the TV version of The Catherine Wheel, Twyla Tharps rock ballet. This video version of the ballet has been even more successful with audiences than the original theater productionit includes some animati

26、on, slow motion, and stop-action freezes that really help the audience understand the dance.The title of the piece refers to Saint Catherine, who died on a wheel in 307 A.D. Nowadays, a Catherine wheel is also a kind of fireworkit lookssomething like a pinwheel. Anyway, the dance is certainly full o

27、f fireworks! Youll see how Twyla Tharp explores one familys attempt to confront the violence in modern life. The central symbol of the work is a pineapple. but exactly what it represents has always created a lot of controversy. As you watch, see if you can figure it out.The music for this piece is f

28、ull of the rhythmic energy of rock music. It was composed by David Byrne. of the rock band Talking Heads? And the lead dancer in this version was Sara Rudner, who is perfectly suited to Tharps adventurous choreography.Following the video, dance teacher Mary Parker will lead a discussion about the sy

29、mbolism Ms. Tharp used. We hope you can stay for that. So, enjoy tonights video. and thank you for your support.1-03-1(woman) In our lab today, well be testing the hypothesis that babies can count as early as five months of age. The six babies here are all less than six months old. Youll be watching

30、 them on closed-circuit TV and measuring their responses.The experiment is based on the well-established observation that babies stare longer if they dont see what they expect to see. First, were going to let two dolls move slowly in front of the babies. The babies will see the two dolls disappear b

31、ehind a screen. Your job is to record, in seconds, how long the babies stare at the dolls when the screen is removed.In the next stage, two dolls will again move in front of the babies and disappear. But then a third doll will follow. When the screen is removed, the babies will only see two dolls. I

32、f were right, the babies will now stare longer because they expect three dolls but only see two.It seems remarkable to think that such young children can count. My own research has convinced me that they have this ability from birth. But whether they do or not, perhaps we should raise another questi

33、onshould we take advantage of this ability by teaching children mathematics at such a young age? They have great untapped potential, but is it good for parents to pressure young children?I-03-2(woman) Before starting our tour of Monticello, Id like to give you some historical facts that might help y

34、ou appreciate what you see today even more.Monticello was the very much loved home of Thomas Jefferson for over fifty years. Jefferson, who was, of course, President, was also a great reader and language enthusiast. He read widely on different subjects, including architecture. He wasnt formally trai

35、ned in architecture, but as a result of his study and observation of other buildings, he was able to help design and build the house. He chose the site himself, naming the estate Monticello, which means little mountain in Italian. In fact, many of the ideas behind the design also came from the Itali

36、an architect Andrea Palladio, who lived in the sixteenth century and who had a great influence on the architecture of England.Jefferson, however, ignored one of Palladios principlesthat is, not tobuild in a high place. Monticellos elevation made the transportation of what was needed at the housefor

37、example, foodespeciallydifficult. But the view from the estate would not be as spectacular if Jefferson had followed Palladios advice； there really is no boundary between the house and the nature around it, and so Jefferson was able to look out on his beloved state of Virginia from his wonderful van

38、tage point.Now well go on to Jeffersons library.I-03-3(man) Now that weve all introduced ourselves to the new members, lets get down to work. As the committee in charge of this years tree-planting project, we have several items on our agenda. First, we have to review the budget. The president has in

39、formed me that the trustees have set aside $3,000 for the purchase of trees. and our environmental T-shirt sale netted a profit of $1,500. Second, we have to finalize the choice of trees. As you know, were working with Richardsons Nursery again this year since everyone seemed pleased with the work h

40、e did for us last year. Mr. Richardson has presented us with several choices within our price range that he thinks would meet our needs. Hes sent us pictures of the trees for us to look at, but he wanted me to tell you that were welcome to visit the nursery if we want to see the trees themselves. La

41、stly, we need to plan some kind of ceremony to commemorate the planting. Several ideas, including a garden party of some sort, have been suggested. So lets get on with it and turn to the first order of business.I-04-1(woman) Welcome to the Four Winds Historical Farm, where traditions of the past are

42、 preserved for visitors like you. Today, our master thatchers will begin giving this bam behind me a sturdy thatched roof able to withstand heavy winds and last up to a hundred years. How do they do it? Well, in a nutshell, thatching involves covering the beams or raftersthe wooden skeleton of a roo

43、fwith reeds or straw. Ourthatchers here have harvested their own natural materials for the jobthe bundles of water reeds you see lying over there beside the barn.Thatching is certainly uncommon in the Untied States today. I guess thats why so many of you have come to see this demonstration. But it w

44、asnt always that way. In the seventeenth century, the colonists here thatched their roofs with reeds and straw, just as they had done in England. After a while, though, they began to replace the thatch with wooden shingles because wood was so plentiful. And eventually, other roofing materials like s

45、tone, slate, and clay tiles came into use.Its a real shame that most people today dont realize how strong and long lasting a thatched roof is. In Ireland, where thatching is still practiced, the roofs can survive winds of up to one hundred ten miles per hour. Thats because straw and reeds are so fle

46、xible. They bend but dont break in the wind like other materials can. Another advantage is that the roofs keep the house cool in the summer and warm in the winter. And then, of course, theres the roofs longevitythe average is sixty years, but they canlast up to a hundred. With all these reasons to s

47、tart thatching roofs again, wouldnt it be wonderful to see this disappearing craft return to popularity?1-04-2(man) A lot of people in the United States are coffee drinkers. Over the last few years, a trend has been developing to introduce premium, specially blended coffeesknows as gourmet coffeesin

48、to theAmerican market.Boston seems to have been the birthplace of this trend. In fact, major gourmet coffee merchants from other cities like Seattle and San Francisco came to Boston, where today theyre engaged in a kind of coffee war with Bostons merchants. They are all competing for a significant s

49、hare of the gourmet coffee market.Surprisingly, the competition among these leading gourmet coffee businesses will not hurt any of them. Experts predict that the gourmet coffee market in the United States is growing and will continue to grow, to the point that gourmet coffee will soon capture half of what is now a 1.5-million-dollar market and will be an 8-million-dollar market by 1999.Stu
