Q: How many Black Friday shoppers were reported to go to the shops at midnight this year？

t. Even when people in different countries eat the same food, they often prepare it very differently. If you were in Germany, you would find soup that is thick and heavy. If you were in China, you would find soup that is thin and clear. On holidays most of us eat special foods. Year after year, even if many other things change, the food is always the same. Sometimes housewives begin weeks in advance to prepare the special foods that are traditionally served on certain holidays.

People in different parts of the world also have different ideas about what is good to drink. Among the most popular hot drinks are coffee and tea. Coffee is very popular in northern Europe and in the Middle East. Some people put cream and sugar in their coffee. But in the United States, many people drink their coffee "black" that is without cream or sugar. Tea is the national drink in China, Japan, and other Oriental(东方的) countries. In the Orient, people drink tea without sugar. But in England where it is also a national drink, many people use both sugar and hot or cold milk in their tea.

People in different parts of the world______.

A．cook the same food in different ways

B．like the same kinds of food

C．have the same ideas about foods

D．know how to prepare the same food

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

After examining a nice black one that cost $5000, he paid for the pearl in cash, shook hands with the jeweler, and left.
