听力原文:Villages in developing countries often lack many things--books, clean water, elec

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 many parts of the world, farmers and their families live in villages or towns.

听力原文: In many parts of the world, farmers and their families live in villages or towns. In the United States, however, each farm family lives on its own fields, often beyond the sight of any neighbors. Instead of traveling from a village to the fields every morning, American farmers stay on their land throughout the week. They travel to the nearest town on Saturdays for shopping or on Sundays for church. The children ride on buses to large schools which serve all of the farm families living in the area. In some areas, there are small schools serving a few farm families, and the children walk to school.

Of course life keeps changing for everyone, including farmers. Today there are cars, good roads, radios, and television sets. And of course there are modern machines for farming. All of these have changed farm life.

For many years, however, farming in America was often a lonely way of living. Farmers had to deal with their own problems, instead of getting help from others. They learned to try new methods, and to trust their own ideas instead of following older ways.

(30)

A.They live in bigger houses.

B.They live in villages or in towns.

C.Each family lives on its own fields.

D.They use modern machines in farming.

听力原文:The very success of satellite communications systems has raised widespread concer

听力原文: The very success of satellite communications systems has raised widespread concern about their future. Some countries are already using satellites for domestic communications in place of conventional telephone lines on land. Although this technique is extremely useful for linking widely scattered villages in remote or mountainous regions, in heavily built-up areas where extensive telephone and telegraph systems already exist, domestic satellites are seen by the land-line networks as unfair competition. Despite such opposition, domestic satellites are gaining support from many businesses and public interest groups in the United States and seem likely to be more widely utilized in the future.

(30)

A.They can be built to be very light.

B.They are inexpensive to operate.

C.They can be directed by remote control.

D.They easily connect distant points.

听力原文: Going through cities and villages, I was attracted by Swedish national flags flying over houses and buildings which were ordinary family houses and offices. I noticed that on the road, all the cars' headlights were turned on even under the sun of June. Mr. Raiding explained that according to the new traffic regulations, drivers were required to keep the lights on day and night, which helped decrease the traffic accidents. Along both sides of the road, there were high fences used to keep the animals living in the forests from rushing onto the road. I could see little bare land in the country. In fact, fifty-four percent of the land is covered by forests and another ten percent by lakes and rivers. I was told that in Sweden nobody has the right to lay the land bare -- whoever cuts the trees Or spoils the grass must restore it right away. Whenever trees are cut, they are replaced by young trees at once.

Around Sweden, there is a notice in the bathroom of every hotel, which reads: "We care for our environment." In Sweden, you cannot see rubbish in streets, public gardens, rivers or lakes. The bottles are made of glass and the packages are made of paper or other natural materials which can be recycled. To make best use of their resources, Swedes never turn on the heating too high or the air-condition too low. The indoor temperature is always kept around twenty-five degrees Centigrade, no matter at home or in large hotels.

(33)

A.Because it would help decrease traffic accidents.

B.Because it was a Swedish custom.

C.Because it was always very dark in Sweden.

D.Because it was always cloudy and rainy in Sweden.

听力原文:Visitors to Britain sometimes are surprised to learn that newspapers there have s

听力原文: Visitors to Britain sometimes are surprised to learn that newspapers there have such a large circulation. The Daily Mirror and the Daily Express both sell about four million copies every day. Apart from the national papers, there is another branch of the British press which sells almost as many copies. Local newspapers have a circulation of 13 million. Almost every town and country area has one.

Local newspapers are written almost entirely for readers interested in local events— births, weddings, deaths, council meetings and sports—but the content is naturally influenced by the kind of community they serve. A great deal of local news is regularly supplied by clubs and churches in the neighborhood and it does not get out of date as quickly as national news.

Local newspapers do not often comment on problems of national importance and editors rarely take sides on political questions. They can often be of service to the community in expressing public feeling on local issues. A newspaper can sometimes persuade the council to take action to provide better shopping facilities, improve transport in the area and preserve local monuments and places of interest.

These papers often sound rather dull and it seems surprising that they all make a profit. However, for many people in small towns and villages the death of someone known to them or the installation of traffic lights at a busy corner nearby can sometimes be more important than a disaster in a foreign country.

(23)

A.Large circulation of newspapers in Britain.

B.National newspapers in Britain.

C.Local Newspapers in Britain.

D.Difference between national newspapers and local newspapers in Britain.

听力原文:Ludwig Van Beethoven was born in Bonn in 1770. Beethoven's first lessons for pian

听力原文: Ludwig Van Beethoven was born in Bonn in 1770. Beethoven's first lessons for piano and violin were from his father. He also studied with Haydon. In 1792 Beethoven came to Vienna, where he decided to stay and try to make a career for himself. In summer months he liked to spend as much time as possible away from the bustle of Vienna. He enjoyed his stays in villages around the city. He liked the peaceful and simple life of the countryside. It was there that he composed both the Fifth and Sixth Symphonies.

Beethoven sympathized with republican ideas. He took great interest in the French Revolution and the birth of the French Republic. He admired its leader, Napoleon, and intended to dedicate his Third or Eroica Symphony to him. However when he was told that Napoleon had crowned himself emperor, the composer was disgusted and changed his mind.

As 1809 drew to its close, Beethoven produced several major works. In May 1809 Haydon died. There was no one to challenge Beethoven to be the musical king of Vienna. At the end of 1813, the Seventh Symphony was performed for the first time.

Beethoven's last years were marked by illness on the one hand and monumental masterpieces on the other. His deafness made it impossible to conduct his works or even perform. any more. Between 1819 and 1823 he composed his Ninth Symphony and some more piano sonatas. Those, together with the late string quartets, were the last works from this great man.

(26)

A.In Bonn.

B.In Vienna.

C.In France..

D.In Haarlem.
