Women generally need less fiber than men.答案:T听力原文 Now, Im going to talk about fiber. Youve heard the advice million times before from our

5、 saloneat more fiber. Now its time to really follow it. Fiber is so important to health that the US Food and Nutrition Board recently said the first recommended daily intakes. Men up to age 50 require 38 grams of fiber daily; women need 25 grams. Men and women over 50 should get 30 grams and 21 gram

6、s respectively. But why does the US Food and Nutrition Board issue the guidelines now? Because the research on fiber keeps piling up. Studies show that certain fibers lower blood pressure and normalize blood sugar, and of course, help with regularity. Since fiber slows digestion and makes you feel f

7、ull, it may be the ticket to slim down. As for cancer, the jury is still out on fibers role in protecting colon, but eating more fiber-rich foods wont hurt. Of course, the best way to get your fiber is to eat whole foods, such as vegetables, whole grains, beans, nuts and seeds. But how much do you n

8、eed to meet recommended levels? According to Doctor Andersons research, it will take a minimum of 6 servings of fruits and veggies and 3 servings of whole grains daily to reach the recommendations. If you fall below that lofty goal, he says, you are a good candidate for a fiber supplement. In partic

9、ular, people with high blood pressure and high blood sugar can benefit from extra fiber. If people who took medicine to lower their blood sugar level, ate a fiber-rich diet and took a soluble fiber supplement daily, 1 quarter could go off their medication. Thats a pretty powerful statement. Just be

10、sure to talk to your doctor before stopping any drug therapy. Selecting a fiber supplement from the dozens on the shelves seems like impossible task, but we can help you cut down your choices or we can provide you with alternative solutions. For example, you can just mix fiber-rich wholly serial wit

11、h milk. But to lower your blood sugar level, reach for a soluble fiber supplement. As far as our research is concerned, there is no evidence that man-made fiber lowers blood pressure or blood sugar levels like other natural fiber products. To avoid common side-effect, such as gas, start with a low f

12、iber dose and slowly walk your way up and insoluble fiber works well for people with irritable bowel syndrome, because it doesnt cause gas. It will help with regularity but it wont lower blood pressure or blood sugar like soluble fiber. For all fiber supplements, follow the package directions. You m

13、ust take the majority of fiber products with a full glass of water. Start with a single dose and walk up to twice daily if needed. Fiber supplements wont block absorption of most medications. But to be safe, we recommend taking fiber supplements either 2 hours before or after your medication, especi

14、ally those feel heart or blood pressure. Thats all about fiber. Do you have any questions? 2. Studies show that fiber can help lose weight.答案:A3. Daily intake of six kinds of fresh fruits and vegetables can help meet the minimum fiber requirement.答案:B4. People who do not get enough fiber from food s

15、hould take fiber supplements.答案:A5. People suffering high blood sugar can be freed from medication if they take a fiber-rich diet.答案:A6. It is hard to find the most suitable fiber supplement on the market.答案:B7. Man-made fiber is as good as natural fiber.答案:B8. Both soluble and insoluble fibers help

16、 lower blood pressure.答案:B9. Although a fiber supplement is not medicine, instructions for taking it should be observed.答案:A10. It is advised that fiber supplements and medicine be taken at the same time.答案:BPart BYou will hear 3 conversations or talks and you must answer the questions by choosing A

17、, B, C or D. You will hear each recording only once. Questions 11 to 13 are based on the following radio program Science around Us. You now have 15 seconds to read Questions 11 to 13.

18、o get electricity.B.It helps to clean the air.C.The exhaust from the plant can be made use of.D.The wasteland around the station can be made use of.答案:C听力原文 Hello, every one, and Im so pleased that youve decided to tunein to our weekly program Science around US. Today, lets look at a new idea of bui

19、lding a special greenhouse in Massachusetts. Green houses in cold climates need a lot of heating. This is expensive. Power stations produce a lot of hot air that is dumped to the atmosphere. This is wasteful. Doctor Berd Johnson, a researcher of Massachusetts Institute of Technology, has connected t

20、hese two facts and proposes to do something about them. He observes that power stations tend to be built far from cities and to be surrounded by wasteland. He suggests building greenhouses on this land anti pumping in the exhaust from the power station. Such greenhouses could be used to grow fruit,

21、vegetables and flowers cheaply. Not only will the exhausts keep the plants warm, it might also fertilize them. Carbon dioxide, the results of burning fuel is, together with water and sunlight, the raw material of photosynthesis. More of it in the air makes plants grow faster. Dr. Johnson is working

22、on the idea in collaboration with Cowpin cooperation, a power company based in San Jose California. Cowpin has a great delight in building pilot greenhouse. Next one of it is natural gas power generating plants, probably, the one in Dayton Massachusetts. The exhaust will be mixed with normal air to

23、cool it from 130 degrees centigrade, the temperature at which it leaves the power station to about 20 degrees centigrade. The temperatures are preferred by tomatoes. Dr. Jonson wants to use a gas-burning rather than a coal or oil-burning plant because the exhaust produced by burning natural gas is f

24、ree from sulfur dioxide, which plants hate. If this idea works, the term greenhouse gas may take on a whole new meaning. Electricity companies could soon be growing tomatoes as a sideline. 2. Which of the following can be used as fertilizer?A.Waste fuel from the power plant.B.Raw materials used to p

25、roduce electricity.C.Waste water from the power plant.D.Carbon dioxide produced from burning fuel.答案:D3. Why does Dr. Johnson want to use a gas-burning plant?A.It generates more hot air.B.It produces more carbon dioxide.C.It does not dump sulfur dioxide into the air.D.It does not release pollutants

27、 doing when he learned about fair trade?A.Studying ecology.B.Working at a museum.C.Founding the friends of the Earth.D.Selling tradecraft products.答案:B听力原文 W: How did you become involved in fair trade? M: My degree was in ecology and I was a founder member of Friends of the Earth in Norridge. It was

28、 all green wally type things and great fun. While I was an education worker of the national history museum in London, a friend introduced me to fair trade, which aims to establish a better deal between the consumers and producers. I started offices for sales agent for tradecraft. Fair trade appeals

29、to me because it combines the environmental and development movements. W: What do you think is the most important next steps in fair trade? M: We need to find out more about the consumers who should he buying fair trade products but arent. Discover what gets in the way. Fair trade in the UK is doing

30、 really well at the moment. Strong companies, like Twin and Equal Exchange, have become actively involved in the main strain and about half a million people regularly buy fair trade goods, But some people still hesitate, because theyre unsure of quality. Also we want to broaden the range of fair tra

31、de products available. W: What has been the highlight of your career in fair trade? M: There is one moment that exits in my mind. When I first joined the fair trade foundation, I visited a tea estate in India to talk to local people and workers. I came away thinking I could raise too many expectatio

32、ns and felt very foreign to them. However, when I returned there 2 years later, I emerged from the plantation gate to find a queue of local people who wanted to talk to me about other changes they hoped for. Two things about this were important. They saw that fair trade existed to improve their situ

33、ation and they showed a level of trust. They could come to me with complaints, knowing it wouldnt be counted against them. 5. What is the next task for fair trade?A.To carry out studies on consumers.B.To involve big companies in fair trade.C.To find out more about its existing market.D.To improve th

34、e quality of fair trade products.答案:A6.

35、Questions 17 to 20 are based on the following interview with Lawrence Lessig, a law professor and director of Public Library of Science (PLoS, an open-access journal publisher) about intellectual property issues. You now have 20 seconds to read Questions 17 to 20. (如需获取本MP3听力录音请搜索标题名) 7. What is spe

36、cial about open-access journals?A.A higher frequency of citation.B.A collection of valuable data.C.Hard-won prominence.D.Established reputation.答案:A听力原文 W: Many scientists support open-access in principle but winning jobs, grands, and tenure still requires publication in journals with established re

37、putations. Can open-access journals, like PLoS, Biology both strap themselves into prominence? M: All the data show that open-access journals have higher citation rates than closed-access journals. That is the reason open-access journals will succeed. There may be a prestige lack, but the value from

38、 open-access will erase that quickly. PLoS has from the start published papers of importance far more than any other start of journal, again a measure of the value of open access. W: In September, the National Institute of Health proposed a new policy requiring all scientists who receive its funding

39、 to make their research results available to the public for free. Could it say the new policy, if adopted, could drive some journals out of business and that taxpayers will have to pay for a new open-access system. Whats your response? M: Taxpayers are paying for the research. The question is how mu

40、ch researcher should have to pay to get access to the results. We believe that the costs of open access publishing will be far less overall than the existing system. The costs to everyone will, thus, be less and the spread of knowledge greater. W: Some worried that proprietary pressures are moving u

41、pstream to a certain ownership of data and researchers themselves rather than patterns and copyrights on the final research products. Did you share this concern? M: Absolutely. Weve expanded intellectual property restrictions without any evidence of the good they will do, and this religion of expans

42、ion will cause substantial harm to researcher and comers. W: Whats the best solution? M: The best solution is that we give up religion in the context of intellectual property and rely upon evidence. No new regulation should be adopted unless the proponent can show with real evidence that the restric

43、tion will do more good than harm. 8. What does the woman say is the possible result of the new policy?A.Some magazines may close down.B.It may provoke criticism from scientists.C.More funding will be offered to scientists.D.Research results will have to be published on a new system.答案:A9. What does

44、Lessig think of the open-access system?A.Taxpayers have to pay as much as usual.B.The costs depend on the research results.C.The costs will be considerably reduced.D.Publishing will be made much easier.答案:C10. What does Lessig say should be done concerning intellectual property expansion?A.Revise re

45、gulations.B.Expand the restriction.C.Identify the harm.D.Make no new restrictions.答案:DPart CYou will hear a speech by Ivo Jupa, who made use of short message service to raise money for charity.

Due to historical reasons, people in the Czech Republic lacked _.答案: a charitable tradition听力原文 When people say that I invented th

47、e Donors Message Service or DMS that raises money for charity, its easy to get the wrong idea. The texting technology was already there, it was just my idea to use it in the new way. Premium rate short messages service or text messaging is used for buying a ring tones or voting via text. My idea was

48、 to use the same tool to get Czechs to give money to charity. Because of some historical reasons, we didnt have much of a charitable tradition here. But last year, through sending DMSs, Czechs donated about 920,000 pounds to dozens of different nonprofit groups. As far as I know, the Czech Republic

49、is the only country in Europe where you can send a text message as a way of giving to charity. 7 years ago, when I was working at a non-profit organization concerned with corporate social responsibility, I attended a conference in Budapest on Africa. I wanted to visit a particular seminar, but it wa

50、s full when I arrived, so I went into another room, not knowing the topic. It was a seminar on individual giving, and I almost left. At that time, there was almost no donating by individuals in my country. We in the non-profit sector have been focused on raising money from institutional foundations.

51、 But we had almost no experience with individual giving, and most of us thought it could never work here. As it turned out, in just one hour this seminar completely changed my thinking. The seminar leader, an American, asked us: In the last two months, how many of you supported a charity? Almost no

52、one raised their hand. Then he asked why nobody had made a donation, no one had an answer. He turned a sheet on a flip chart. It showed that 85% of people said they didnt support a charity because they were never asked. This got me thinking of ways to make it really simple for Czechs to make donatio

53、ns. I wondered if we could collect donations via text messages, which is quick and easy and a new technology that young people will use. So I started to discuss this with the main wireless providers in the Czech Republic. They agreed to set up a single number to which people could send an SMS and ma

54、ke donations to a variety of charities, big and small. The mobile operators recognized its a win-win situation and agreed to take money only for operating costs. We set a very modest amount, 72 pence, which anyone can give. The program really took off in 2004, when a terrible storm hit the High Tatr

55、a mountains in Slovakia, which is a favorite holiday destination for Czechs. Trees were toppled everywhere, and Czechs really wanted to help. Some TV programs started putting out the name of a group that was doing recovery work, and explained how people could donate to them via DMS. Suddenly, people

56、 discovered the DMS, and in the end, the Czechs collected far more money than the Slovaks. When the program started, I guessed it would work if one million DMSs could be sent every yearthat would mean one for every ten people in the Czech Republic. Last year, Czech sent 1.5 million DMSs, so its a bi

57、g success. Now were talking with groups in other European countries about setting up similar programs. My formal education had been in teacher training, and in the 1990s, I got involved with groups that were working to modernize Czech schools and teaching methods, For a time, I worked at the Czech E

58、ducation Ministry, where I was in charge of European Structural Funds. Over the past ten years, Ive been overseeing people and budgets, and I realized they needed to get proper training in management, so last year I enrolled in an executive MBA program. One of the most satisfying moments for me was when a friend who had a pub told me about a group of men who had come in. They
