Archimedes is most well-known for one specific idea that he came up with. "Archimede's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.
It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.
A good title for the selection is ______.
A．Archimedes
B．Archimedes' Principle
C．A gold and silver crown
D．The king of Syracuse
Mr. Flowers' glasshouse was close to a public path, which was always used by children walking to and from school. Boys were often attracted to throw a stone or two at his glasshouse. So Mr. Flowers did his best to be in or close by his glasshouse at the beginning and end of the school day.
However, it was not convenient or possible to be on guard all the time. Mr. Flowers had tried in many ways to prevent harm to his glass; but nothing that he had done had been successful.
Then, just as he was giving up hope of ever winning the battle, and of growing the Rose of the Year, he had a truly wonderful idea. He put up a large notice made of good, strong wood, some metres away from the glasshouse, where it could be' clearly seen from the path. He had painted on the board the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble. The boys were much more attracted to throw stones at the notice than at the glasshouse.
Mr. Flowers' great hope is ______.
A．to grow beautiful flowers
B．to grow the Rose of the Year and win a prize
C．to grow all kinds of flowers in the world
D．to take part in the competition
Most of the money today is made of metal or paper. But people used to use all kinds of things as money. One of the first kinds of money was shells.
Shells were not the only things used as money. In China, cloth and 'knives were used. In the Philippine Islands, rice was used as money. In some parts of Africa, cattle were one of the earliest kinds of money. Other animals were used as money, too.
The first metal coins were made in China. They were round and had a square hole in the center. People strung them together and carried them from place to place.
Different countries have used different metals and designs for their money. The first coins in England were made of tin. Sweden and Russia used copper to make their money. Later, other countries began to make coins of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. (80)The first paper money looked more like a note from one person to another than paper money used today.
Money has had an interesting history from the days of shell money until today.
Which of the following can be cited as an example of the use of money in exchange for services？
A．To sell a bicycle for $ 20.
B．To get some money for old books at a garage sale.
C．To buy things you need or want.
D．To get paid for your work.
Passage Three
Questions 31 to 35 are based on the following passage.
In the late 1960's many people in North America turned their attention to environmental problems，and new steel-and-glass skyscrapers(摩天楼)were widely criticized. Scientists pointed out that blocks of tall buildings in a city often overburdens. public transportation and parking lot capacities.
Skyscrapers are also big consumers，and wasters，of electric power. In one recent year. the addition of 17 million square feet of skyscraper office space in New York City raised the peak daily demand for electricity by 120，000 kilowatts-enough to supply the entire city of Albany，New York，for a day.
Glass-walled skyscrapers can be especially wasteful. The heat loss(or gain)through a wall of half-inch plate glass is more than ten times that through a typical brick wall filled with insulation board. To lessen the strain on heating and air-conditioning equipment，builders of skyscrapers have begun to use double-glazed(装上玻璃的)panels of glass，and reflective glasses coated with silver or gold mirror films that reduce glare as well as heat gain. However. mirror-walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings.
Skyscrapers put a severe strain on a city's sanitation(卫生)facilities，too. If fully occupied, the two World Trade Center towers in New York City would alone generate 2.25 million gallons of raw wastes each year-as much as a city the size of Stamford，Connecticut，which has a population of more than 109，000.
Skyscrapers also interfere with television reception，block bird flyways，and obstruct air traffic. In Boston in the late 1960's，some people even feared that shadows from skyscrapers would kill the grass on Boston Common.
Still，people continue to build skyscrapers for all the reasons that they have always built them-personal ambition(抱负)pride，and the desire of owners to have the largest possible amount of rentable space.
The main purpose of the passage is to______.
A. compare skyscrapers with other modem structures
B. describe skyscrapers and their effect on the environment
C. advocate the use of masonry(化妆舞会)in the construction of skyscrapers
D. illustrate some architectural designs of skyscrapers
One country received its second-place medals with visible indignation after the hockey. There had been noisy scenes at the end of the hockey match, the losers objecting to the final decisions. They were convinced that one of their goals should not have been disallowed and that their opponents' victory was unfair. Their manager was in a rage when he said, "This wasn't hockey. Hockey and the International Hockey Federation are finished." The president of the Federation said later that such behavior. could result in suspension of the team for at least three years.
The American basketball team announced that they wouldn't yield the first place to Russia, after a disputable end to their contest. The game had ended in disturbance. It was thought at first that the United States had won, by a single point, but it was announced that there were three seconds still to play. A Russian player then threw the ball from one end of the court to the other, and another player popped it into the basket. It was the first time the USA had ever lost an Olympic basketball match. An appeal jury debated the matter for four and a half hours before announcing that the result would stand. The American players then voted not to receive the silver medals.
Incidents of this kind will continue as long as sport is played competitively rather than for the love of the game. The suggestion that athletes should compete as individuals, or in non-national teams, might be too much to hope for. But in the present organization of the Olympics there is far too much that encourages aggressive patriotism.
According to the author, recent Olympic Games have______.
A．created goodwill between the nations
B．bred only false national pride
C．barely showed any international friendship
D．led to more and more misunderstanding and hatred
