听力原文： Villages in developing countries often lack many things--books, clean water, electricity. These shortages are easy to see. But a different kind of shortage is not easy to see. That is a shortage of experts. Many villages have no doctors, engineers or scientists. They have no one who knows how to treat unusual medical problems or design a new expert system. There's a way to ease these problems. They can do it with computers. In the past few years, computer scientists around the world have developed what they call expert systems. An expert system is a special kind of computer program. In some situations, it can take the place of a human expert. For example, an expert in medical system can help care for a sick person. A question appears on the computer screen, "Is the person hot？" You tell the computer either yes or no. The computer asks other questions. "Has the person lost any blood？" "Can the person move normally？" You answer. The computer continues to ask questions until it has enough information to make a decision. Then it tells what medicine or other treatment is needed. In this way the expert system takes the place of a doctor. Another kind of expert system takes the place of an engineer. It measures the flow of water in a river. It tells if a dam can be built on the river. It also tells how much electricity can be produced. Still other kinds of expert systems help solve problems for farmers and owners of small businesses.

听力原文： In all economic systems today, most businesses of any size rely on one system of organization: the division of labor. This means that the workers are specialized. Each worker has a particular duty to perform. as one part of the whole operation.
A good example of the division of labor is an assembly line in an automobile factory. One worker may install a door while another adds lights. Normally, workers stay in one place, and a conveyor belt moves the product to them. If one worker had the responsibility of producing an entire car, he or she might be able to complete one each year. By comparison, factories with assembly lines may produce an average of about thirty-five cars a years per worker.
The division of labor permits mass production, but it does have some disadvantages. For one thing, few people know or understand all aspects of an operation, In addition, mass production may be more efficient, but many workers complain that they get little job satisfaction from working on one small duty, day after day, To them, there is much more satisfaction in doing a job from beginning to end.

M: Yes, I am. I can't live without it.
W: What type of music do you like the most？
M: I enjoy listening to almost all categories of music -- classical, jazz, country-western, the heavy metal type of rock ... Yes, my favorite music is new age -- I'm really very fond of it.
W: I'd suggest that you should major in music instead of English.
M: Absolutely. But English is fine. I like English as much as music. I wish I were a double major. Actually I'm more fascinated and delighted with the hardware of music reproduction.
W: The hardware of music reproduction？
M: I mean musical instruments, such as the bone whistles of the Stone Age and the digital Synthesizers of this age.
W: You certainly are an expert on music. May I ask you a question？
M: Sure.
W: I hear people talk about "hi-fi". Is it a sound system or something else？
M: It's popularly known as a stereo system. A more accurate definition is a stereo system that reproduces music very realistically with high fidelity quality. In the early stage, a hi-fi system used compact cassettes containing magnetic tape.
W: A cassette-tape player？
M: Right, but the weakness is that it produces annoying "hiss" noise while playing.
W: This was one of the reasons why I bought a CD player when the cassette player broke down.

Eating Potatoes Gives Your Immune System a Boost
Eating potatoes is not only good for bowel health, but also for the whole immune system, especially when they come in the form. of a potato salad or eaten cold. In a study on an animal model, researchers in Spain found that pigs fed large quantities of raw potato starch (RPS) not only had a healthier bowel, but also decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease, generally when the body is challenged.
The general down-regulation of leucocytes observed by the Spanish researchers suggests an overall beneficial effect, a generally more healthy body. The reduction in leucocytes levels was about 15 percent. Lower lymphocyte levels are also indicative of reduced levels of inflammation, but the observed reduction in both lymphocyte density and lymphocyte apoptosis is surprising.
In what was the longest study of its kind, pigs were fed RPS over 14 weeks to find out the effect of starch on bowel health. "The use of raw potato starch in this experiment is designed to simulate the effects of a diet high in resistant starch. " said study leader Jose Francisco Perez at the University Autonoma de Barcelona, Spain.
Humans do not eat raw potatoes, but they do eat a lot of foods that contain resistant starch, such as cold boiled potatoes, legumes, grains, green bananas, pasta and cereals. About 10 percent of the starch eaten by human is resistant starch--starch that is not digested in the small intestine and so is shunted into the large intestine where it ferments. Starch consumption is thought to reduce the risk of large bowel cancer and may also have an effect on irritable bowel syndrome (IBS).
Immunology expert Lena Ohman's team previously found that the overall lymphocyte levels do not vary for IBS patients, but that lymphocytes are transferred from the peripheral blood to the gut, which support the hypothesis of IBS being at least partially an inflammatory disorder. She says the decrease in lymphocytes observed by the Spanish is therefore interesting, and a diet of resistant starch may be worth trying in IBS patients. Ohman is currently at the Department of Internal Medicine, Goteborg University, Sweden. The study is published in the journal Chemistry and Industry, The magazine of the SCI.
What form. of potato is the most nutrient to the human body？
A．Potato soup.

SUBJECT: Grand Opening Ceremony
Hello Mr. Dawson,
It was really pleased to talk to you on the phone earlier today. As I hope I made clear to you, it is absolutely essential that we have the sound system package we ordered set up on time, as per the contract signed last week. Ceremonies begin on April 27 at 6:00 p.m. sharp. Your set-up schedule is to include a complete sound check. We don't need a repeat of last time.
Please note that due to construction, it is impossible to use Gate 1. So please have your trucks arrive at Gate 4, by 11:00 A.M. Our staff will call a construction foreman to escort you to the loading bays. In keeping with safety requirements, ensure your crew is equipped with safety vests and safety helmets, or our staff will ask them to leave the site.
If you have any special electrical needs, please contact Philip Jackson, our plant manager. His cell phone number is 604-555-4123.

TO: Mr. Andrew Kim
SUBJECT: Re: Grand Opening Ceremony
Dear Mr. Kim,
It was good to have spoken to you yesterday in person. I wish to assure you that in my new position here at Perfect Sound I will try to provide you with as seamless a process as possible.
Our sound expert, Michael Johnson, is currently scheduled to arrive at 3:00 P.M. to run the sound check, which we think will give us plenty of time to ensure everything will be up and running by the 7:00 P.M. start time.
I note that our installation personnel will be required to wear safety vests and safety helmets. I think this requirement does not apply to Michael because he is not involved in the actual physical set-up.
As regards electrical needs, I have already e-mailed Mr. Jackson all the necessary information. Please feel free to call me at 556-7658 with any concerns you may have.
Thank you for selecting Perfect Sound!
Sincerely,
Robert Dawson
Vice President
