ntrasts. He was the son of a bankrupt man, but became a millionaire; a scientist with a love of literature, an industrialist who managed to remain an idealist. He made a fortune but lived a simple life, and although cheerful in company he was often sad in private. A lover of mankind, he never had a wife or family to love him; a patriotic son of his native land, he died alone on foreign soil. He invented a new explosive, dynamite, to improve the peacetime industries of mining and road building, but saw it used as a weapon of war to kill and injure his fellow men. He was born in Stockholm on October 21, 1833 but moved to Russia with his parents in 1842. Most of the family returned to Sweden in 1859. He had never been to school or university but had studied privately. He was imaginative and inventive, but he had better luck in business and showed more financial sense. His greatest wish was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause until his death in Italy in 1896.

听力原文： One of the main complaints of city residents, not surprisingly, is the lack of parking. This problem is partly caused by all the abandoned cars on the streets. It has been estimated by A to Z Towing, Inc., a nationwide tow-truck agency, that over one million cars are abandoned on the streets and alleyways of the nation's cities. Each year approximately a third of those cars are moved and destroyed. The rest of the cars which are not removed take up parking spaces and make neighborhoods look rundown.

A survey of twenty cities by A to Z reports that as much as 30 million dollars is spent annually to tow away and dismantle abandoned vehicles. One city alone, Los Angeles, spends five million dollars a year to control the accumulation of abandoned cars on its streets. Even though the city spends so much money on the program, it is always fighting a losing battle as more and more cars are constantly coming off the production line.

Boston, on the other hand, which spends most of its money on museums and libraries, does not appropriate tax money to clean abandoned cars off the streets. In Boston the problem has been dealt with by a non-profit governmental agency called Street Horizons, which uses the money from the recycling of the metal in the cars to pay for the cost of towing them The program in Boston sounds good although it has not completely reached financial independence from the federal government yet. Until a truly self-sufficient program for removing old cars is developed, it will remain a serious problem

B．Thirty million old cars.

听力原文： It's very necessary for Canada to set up effective transportation system because of its enormous size with its sparsely populated distribution. It is also very difficult to make transportation construction on the surface of the country due to its harsh long winter and its mountainous terrain. It's really amazing for this country to set up a transcontinental railroad since last century. Much of the country's freight is transported by Canadian National Railway and Canadian Pacific Railway. But nowadays fewer and fewer people travel by train.

Water transportation was very important before railway construction. Although passenger travel by water is less important than before, waterways remain important for cargo transporting. Waterways include lakes, rivers and sea coastlines.

Because of the increasing number of automobiles, Canada's road transportation develops very quickly. In 1991, road length has been more than 849,400 kilometers. Road system is becoming more and more important. Trucks carry nearly half of the total freight transported in Canada.

With the development of transportation, airplanes became another necessary vehicle since airplanes could be the only access to some areas of the far northern region.

Canadian transportation system develops very quickly with the increasingly advanced science and technology. The aim of the transportation is to use substitute fuels and to produce more efficient transportation facilities.

C．The condition of transportation system in Canada.

What Is Death？

People in the past did not question the difference between life and death. They could see that a person died when his heart stopped beating. People have learned, however, that the body does not die immediately when the heart stops beating. They discovered that we remain alive as long as our brain remains active. Today the difference between life and death is not as easy to see as in the past. Modern medical devices can keep the heart beating and the lungs breathing long after the brain stops. But is this life？

This question has caused much debate among citizens in the United States. Many of them want a law that says a person is dead when the brain dies. A person should be considered dead when brain waves stop even if machines can keep the body alive. Such a law would permit doctors to speed removal (切除) of undiseased (没病的) organs for transplant (移植) operations.

The brain is made of thousands of millions of nerve cells. These cells send and receive millions of chemical and electrical messages every day. In this way the brain controls the other body activities. Nerve-cell experts say it usually is easy to tell when the brain has died. They put small electrodes (电极) on a person's skull (头骨) to measure the electrical signals that pass in and out of the brain. These brain waves are recorded on a television screen or on paper. The waves move up and down every time the brain receives messages from the nerve cells. The brain is dead when the waves stop moving.

Although there are people who oppose the idea of a law on brain block for variouis reasons, the idea of brain wave activity as a test of death is slowly being accepted.

People in the past held that the difference between life and death______.

A．was easy to tell

B．did not exist

C．lay in the brain

D．was open to debate
