听力原文：A design for a remotely-controlled fire engine could make long road or rail tunne

ls safer. It is the brainchild of an Italian fire safety engineer, who claims that his invention — dubbed Robogat — could have cut the death toll in the disastrous Mont Blanc tunnel fire in March 1999, which killed 41 people. Most of the people died within 15 minutes of smoke first being detected. Quick action is needed when fire breaks out in a tunnel. Robogat can travel at about 50 kilometers per hour. The Mont Blanc fire was five kilometers from the French end of the tunnel, so a machine could have got there in about 6 minutes.

The robot bas been designed and patented by Domenico Piatti of the Naples fire department. It runs on a monorail suspended from the roof of the tunnel. When the Robogat reaches a fire, it plugs into a water pipe running along the tunnel, and directs its hoses at the base of the fire. It is capable of pumping 3,000 liters of high-pressure water per minute—about the same rate as that from an airport fire tender. Normal fire engines deliver 500 liters per minute.

Question ：What is the main function of Robogat？

(33)

A．Make long road or rail tunnels safer.

B．Make long road or rail tunnels easier.

C．Make long road or rail tunnels quicker.

D．Make long road or rail tunnels more efficient.

听力原文：The modern sailing ship was developed by a man who never went to sea. He was Prin

听力原文： The modern sailing ship was developed by a man who never went to sea. He was Prince Henry of Portugal, the younger son of the Portuguese King and an English princess.

Prince Henry lived in the 15th century. As a boy he became devoted to the sea, and he dedicated himself to improving the design of ships and the methods of sailing them. In 1416, Henry founded a school for mariners, to which he invited everyone who could help him--Jewish astronomers, Italian and Spanish sailors, and Arab mathematicians and map makers who knew how to use the crude compass of the day and improve it.

Henry's goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the shore. The caravel carried more sail and was longer and slimmer than any ship then made, yet was tough enough to withstand gales at sea. He also developed the carrack, which was a slower ship, but one that was capable of carrying more cargo.

To Prince Henry the world owes credit for the development of craft that made oceanic exploration possible. He lives in history as "Prince Henry the Navigator".

(30)

A．To help mariners.

B．To improve ship design and sailing methods.

C．To study astronomy and mathematics.

D．To improve his own skill as a sailor.

听力原文： Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem; (29)it seemed impossible to get the thread to run smoothly around the needle. Though he was tired, Howe so, Howe ran into the salve problem as before. (29)The thread kept getting caught, around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised, hut suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that (30)he bad just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practiced sewing machine．(31)Elias Howe was not the only one who found the answer to his problem in this way. Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.

听力原文："High tech "and "state of the art" are two expressions that describe very modern

听力原文： "High tech "and "state of the art" are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system or device that uses the newest ideas or discoveries of science and engineering.

What is high tech？ A computer is high tech. So is a communications satellite. A modern manufacturing system is surely high tech.

High tech became a popular expression in the United States during the early 1980's. Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave ovens, etc.

"State of the art" is something that is as modern as possible. It is a product that is based on the very latest methods and technology. Something that is "state of the art" means the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modern electronic design and parts. It is the best that one can buy.

"State of the art" is not a new expression. Engineers have used it for years, to describe the best and most modern way of doing something.

Millions of Americans began to use the expression in the late 1970's. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art".

Computer technology changed so fast that a state of the art computer today might be old tomorrow. The expression "state of the art" became as common and popular as computers themselves. Now all kinds of products are said to be "state of the art".

A．To tell what "high tech" and "state of the art" are.

B．To tell how "high tech" and "state of the art" have developed.

听力原文：The basic flag of the United States is one of the world's oldest national flags.

听力原文： The basic flag of the United States is one of the world's oldest national flags. Only the basic flags of Austria, Denmark, Great Britain, the Netherlands, Sweden, and Switzerland are older.

The first official flag of the United States was created by Congress on June 14,1777. It consisted of 13 alternate red and white stripes and 13 white stars in a field of blue, representing the 13 colonies that had declared their independence in 1776. Congress adopted a new flag of 15 stars and 15 stripes in 1795, to give representation to the two new states admitted into the Union, Vermont and Kentucky.

By 1817, there were 20 states in the Union, and it became apparent that adding one stripe for each new state would destroy the shape of the flag. As a result, in 1818, congress restored the design of 13 stripes and provided that each state was to be represented by one star. In 1912 President William H. Taft made the first official provision for the arrangement of the stars. He ordered that there be six even rows of eight stars each. Previously, the arrangement of the stars had been left to the flag-maker's fancy.

The evolution of the Stars and Stripes reflects the growth of the United States. After the admission of Hawaii into the Union in 1959, the flag was officially changed for the 26th time since its creation.

(33)

A．New Zealand.

B．Australia.

C．Denmark.

D．Norway.

听力原文：As the car industry develops, traffic accidents have become as familiar as the co

听力原文： As the car industry develops, traffic accidents have become as familiar as the common code. Yet, their cause and control remain a serious problem that is difficult to solve. Experts have long recognized that this discouraging problem has multiple causes. At the very least, it is a problem that involves three factors: the driver, the vehicle, and the roadway, ff all drivers exercise good judgment at all times, there would be few accidents. But that is rather like saying that ff all people were honest, there would be no crime. Improved design has helped make highways much safer. But file type of accidents continued to rise because of human failure and an enormous increase in the numbers of automobiles on the road. Attention is now turning increasingly to the third factor of the accident, the car itself. Since people assume that the accidents are bound to occur, they want to know how cars can be built better to protect the drivers.

(33)

A．The causes are obvious.

B．The causes are very complicated.

C．Tile causes are familiar.

D．The causes are not well understood.

M: Yes.for my history of architecture class.

W: Oh,I am taking it now andI have to do some research on industrial architecture.I need to read up on Kahn's factories. So I would like to see what you wrote about them.

M: I don't think my paper will help；I focus on his classical design like Clements library and office buildings. but you are interested in the modem building he is famous for.

W: Yes,he is best known for his factory,especially the auto plants in Detroit.He made a breakthrough in industrial design.You know before his time,factories were so narrow and inefficient,but his factory provided enough light and air and open space. So the cars could be assembled in one huge plant.

M: I remember reading that previously.factories had wooden frames and the heavy machinery made the buildings vibrate and there were fire hazards too.But when Kahn started to design auto plants around the turn of the century,reinforced concrete had just been invented.With the reinforced concrete,not only were the buildings solid and fireproof but they were cheap to put up too!

W: You seem to know a lot of about his industrial career.

M: Actually even though I wrote about his other works,I did a lot of background reading.Let me see if I can dig up that paper for you.There were some books of articles included in my bibliography that you might want to look up at the library.

W: Thank you.It will be a great help for me.
