18、ill hear a talk by Prof Wilson, a health expert, on the importance of fiber in our daily diet. As you listen, answer Questions 1 to 10 by circling TRUE or FALSE. You will hear the talk only once.（分数：30.00）(1).Women generally need less fiber than men.（分数：3.00）A.正确 B.错误解析：听力原文 Now, Im going to talk ab

19、out fiber. Youve heard the advice a million times before from our 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 nee

20、d 25 grams. Men and women over 50 should get 30 grams and 21 grams 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

21、with regularity. Since fiber slows digestion and makes you feel full, 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 veget

22、ables, whole grains, beans, nuts and seeds. But how much do you need 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

23、 says, you are a good candidate for a fiber supplement. In particular, 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

24、off their medication. Thats a pretty powerful statement. Just be 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 solu

25、tions. For example, you can just mix fiber-rich wholly serial with 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 prod

26、ucts. To avoid common side-effect, such as gas, start with a low fiber 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 fibe

27、r. For all fiber supplements, follow the package directions. You must 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

28、supplements either 2 hours before or after your medication, especially those feel heart or blood pressure. Thats all about fiber. Do you have any questions?(2).Studies show that fiber can help lose weight.（分数：3.00）A.正确 B.错误解析：(3).Daily intake of six kinds of fresh fruits and vegetables can help meet

32、（分数：9.00）(1).Why does Dr. Johnson suggest building a greenhouse near a power station? A. It is convenient to 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.（分数：3.00）A.B.C. D.解析：听力原文 Hello, everyo

33、ne, and Im so pleased that youve decided to tune in to our weekly program “Science Around US“. Today, lets look at a new idea of building 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 dum

34、ped to the atmosphere. This is wasteful. Doctor Berd Johnson, a researcher of Massachusetts Institute of Technology, has connected these 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

35、building greenhouses on this land and pumping in the exhaust from the power station. Such greenhouses could be used to grow fruit, vegetables and flowers cheaply. Not only will the exhaust keep the plants warm, it might also fertilize them. Carbon dioxide, the results of burning fuel is, together wi

36、th water and sunlight, the raw material of photosynthesis. More of it in the air makes plants grow faster. Dr. Johnson is working 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 i

37、t is natural gas power generating plants, probably, the one in Dayton Massachusetts. The exhaust will be mixed with normal air to 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.

38、Johnson wants to use a gas-burning rather than a coal or oil-burning plant because the exhaust produced by burning natural gas is free 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 to

39、matoes 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 produce electricity. C. Waste water from the power plant. D. Carbon dioxide produced from burning fuel.（分数：3.00）A.B.C.D. 解析：(3).Why does Dr. Johnson want to use a g

40、as-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 into the air.（分数：3.00）A.B.C.

41、king at a museum. C. Founding the friends of the Earth. D. Selling tradecraft products.（分数：3.00）A.B. C.D.解析：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 all green wally type things and great fun.

42、 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 to me because it combines the environmental

43、 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 be buying fair trade products but arent. Discover what gets in the way. Fair trade in the UK is doing really well at the moment. Strong companie

44、s, like Twin and Equal Exchange, have become actively involved in the main stream 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 trade products available. W: What has been the

45、 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 expectations and felt very foreign to them. However,

46、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 situation and they showed a level of trust. The

47、y could come to me with complaints, knowing it wouldnt be counted against them.(2).What is the next task for Fairtrade? 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 the quality of fair trade products.（分数
