Passage Three An old Indian story says that the game of chess （国际象棋) was invented

Passage Three

An old Indian story says that the game of chess (国际象棋) was invented by Sissa Ben, Prime Minister of King Shirham. As soon as the invention was finished he gave it to the king, who was glad and asked him what he would like to have in return. To the king's surprise, what Sissa wanted seemed very little. "Your Majesty, "said the minister, kneeling before the king. "I want nothing but some wheat. Please put a grain of wheat on the first square of the chessboard (棋盘), two on the second, four on the third, eight on the fourth.., and so on, doubling the number for each following square. Give me enough grains to cover the 64 squares of the chessboard."

"You don't ask for much, my honest servant. You might have asked for gold or money," said the king and then ordered a bag of wheat brought to the palace.

But when the counting began, with one grain for the first square, two for the second, four for the third, and so on, the bag was emptied before the 20th square. More bags were brought, but the number of grain needed for the following squares increased so rapidly that the king was not able to keep his promise even with all the crops in the whole India! In fact, he would have needed 8 466 744 073 709 511 615 grains, which would be as much as that they would produce in about 2000 years!

Now tile king found himself deep in debt to his minister. He had either to face the terrible trouble all his life or to cut off Sissa's head, the litter of which, it is said was what he finally chose.

41. This story tells us ______.

A. how cruel the king was

B. how clever the minister was

C. Sissa was a famous mathematician

D. how the game of chess came into being

第3题

Mathematical ability and musical ability may not seem on the surface to be connected, but

people who have researched the subject—and studied the brain—say that riley are. Three quarters of the bright but speech-delayed children in the group I studied had a close relative who was an-engineer, mathematician or scientist and four fifths had a close relative who played a musical instrument. The children themselves usually took readily to math and other analytical subjects and to music.

Black, white and Asian children in this group show the same patterns. However, it is clear that blacks have been greatly overrepresented in the development of American popular music and greatly underrepresented in such fields as mathematics, science and engineering.

If the abilities required in analytical fields and in music are so closely related, how can there be this great discrepancy？ One reason is that the development of mathematical and other such abilities requires years of formal schooling, while certain musical talents can be developed with little or no formal training, as has happened with a number of well-known black musicians.

It is precisely in those kinds of music where one can acquire great skill without formal training that blacks have excelled popular music rather than classical music, piano rather than violin, blues rather than opera. This is readily understandable, given that most blacks, for most of American history, have not had either the money or the leisure for long years of formal study in music.

Blacks have not merely held their own in American popular music. They have played a disproportionately large role in the development of jazz, both traditional and modern. A long string of names comes to mind—Louis Armstrong, Charlie Parker... and so on.

None of this presupposes any special innate (先天的) ability of blacks in music. On the contrary, it is perfectly consisted with blacks having no more such inborn ability than anyone else, but being limited to being able to express such ability in narrower channels than others who have had the money, the time and the formal education to spread out over a wider ranger of music, as well as into mathematics, science and engineering.

What is the main idea of the first paragraph？

A．Mathematical ability and musical ability are connected.

B．Mathematical ability has more to do with the brain than musical ability.

C．More people are good at music than math.

D．More research should be done into the relationship between mathematical ability and musical ability.

第7题

The United States has a major problem on its hands. True, Britain is facing a similar prob

lem, but for the timebeing it is in America that it is graver. The only way to solve it is through education. Negroes (黑人．should knowabout the contributions that black individuals and groups have made towards building America. This is of vitalimportance for their self-respect; and it is perhaps even more important for white people to know. For if you believethat a man has no history worth mentioning, it is easy to assume that he has no value as a man. Many people believe that, since the Negros achievements do not appear in the history books, he did not haveany. Most people are taken aback when they learn that.Negroes sailed with Columbus, marched with the Spanishconquerors of South America and fought side by side with white Americans in all their wars. People are astonishedwhen you tell them about Phillis Wheatley, who learned English as a salve in Boston and wrote first-class poetry.They have never heard of Benjamin Banneker, a mathematician and a surveyor, who helped to plan the city ofWashington. There has been a tendency all along to treat the black man as if he were invisible. Little has beenwritten about the 5,000 American Negroes who fought in the Revolution against the British, but they were in everyimportant battle. In the Anglo-American War of 1812, at least one out of every six men in the U.S. Navy was aNegro. In the Civil War, more than 200,000 black troops fought in the Union forces. How, then, did the image of the Negro as a valiant fighting man disappear？ To justify the hideous institutionof slavery, slave-holders had to create the myth of the docile, slow-witted Negro, incapable of self-improvement, and even contented with his lot. Nothing could be further from the truth. The slave fought for his freedom at everychance he got, and there were numerous uprisings. Yet the myth of docility persisted. There are several other areas where the truth has been twisted or concealed. Most people have heard of theNegro, Carver, who invented scores of new uses for the lowly peanut. But whoever heard of Norbert Rillieux, whoin 1846 invented a vacuum pan that revolutionized the sugar-refining industry？ Or of Elijah McCoy, who in 1872invented the drip cup that feeds oil to the moving parts of heavy machinery？ How many people know that Negroesare credited with inventing such different items as ice creams, potato chips, the gas mask and the first traffic light？ Not many. As for the winning of the West, the black cowboy and the black frontiersman have been almost ignored, though film producers are becoming more aware of their importance. Yet in the typical trail crew of eight men thatdrove cattle from Texas to Kansas, at least two would have been Negroes. The black troops of the Ninth and TenthCavalry formed one-fifth of all the mounted troops assigned to protect the frontier after the Civil War. "Whatdifference does it make？" you may ask. A lot. The cowboy is the American folk-hero. Youngsters identify withhim instantly. The average cowboy film is really a kind of morality play, with good guys and bad guys and rightfinally triumphing over wrong. You should see the amazement and happiness on black youngsters faces when theylearn that their ancestors really had a part in all that. According to the passage, education on Negroes contributions to America ___________

A.contributes to the blacks confidence of their value

B.proves their achievements in building the country

C.is still a major task for curriculum education

D.will solve all the conflicts between black and white people

Passage Four Archimedes was a famous Greek mathematician and scientist. He was born arou

Passage Four

Archimedes was a famous Greek mathematician and scientist. He was born around 287 BC and he died in the year 212 BC.

Archimedes is most well-known for one specific idea that he came up with. "Archimedes'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.

48. A good title for the selection is______.

A. Archimedes

B. Archimedes's Principle

C. A Gold and Silver Crown

D. The King of Syracuse
