People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3000 years ago. By the time the Chinese silk trade became important in the world, the Silk Road covered almost 6500 kilometers. It spread from Rome to China, which is from the West to the Far East.Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices(香料),cloth, valuable stones and gold.There is a famous old story along the old road. It is said that Roman soldiers travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Some of these Romans married local Chinese women and the story of blue-eyed villages of China was started.During its busiest period, .the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.In modem times, the old Silk Road routes(路线)are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35,000. objects from all along the Silk Road.

As a result, European automakers used to make different kinds of small cars while American automakers used to build bigger, heavier cars. However, these days, automakers in both America and Europe produce cars of different sizes. This is because most automakers export their cars all over the world.The price of gasoline (汽油)is one reason for differences in car choices. Since gasoline is more expensive in Europe, many Europeans want smaller, lighter cars that will travel a long way on a gallon(加仑)of gasoline.Other reasons also enter into the big or little car decision. Many European cities have narrow, winding(弯曲的)streets. In these cities a small car is easier to control than a large one.For a long time, few Americans bought small cars. Instead they chose large cars, because these roomy cars were more comfortable for large families and long trips. Some people also liked the powerful engines(发动机)that large cars had. Since gasoline was cheap, drivers did not mind that the large cars used a lot of gasoline.But in the 1970s, there were gasoline shortages in the United States. The price of gasoline went up. Though large cars were still more popular than smaller cars, sales of small cars increased. Some people also bought small cars becausethese cars caused less air pollution than larger cars.Today, Americans' car preferences are still changing. Though Americans are still buying many small cars, the fastest growing sales are for certain kinds of large cars. These types of cars are called minivans and sport utility vehicles(SUV). They are very popular today. But of course, that could change tomorrow.1.In the 1970s, .A.large cars were less popular than smaller cars.B.European cars finally came to the United States.C.the price of gasoline went up in the United States.D.people in the United States stopped buying small cars.2.Which of the following does the article lead you to believe?A.Sport utility vehicles small cars.B.Minivans are becoming less popular.C.European car companies sell many cars in America.D.Cars with powerful engines caused less air pollution.3.What does “roomy” in Paragraph 4 mean?A.having much space B.having little spaceC.having a large room D.having a small room4.What can we infer(推断)from the article?A.Small cars are better than large cars.B.The price of gasoline is always rising.C.Large cars will always be popular in the United States.D.People like to have different kinds of cars to choose from.C15、Amy was looking for a gift for her little daughter. She stopped in front of a store full of dolls.“Girls like dolls,” she thought as she stepped into the store.Looking around, she saw a grandma doll — one with grey hair and a pair of glasses. In her mind appeared Joyce, her own mother.When Amy was a little girl, she got her first doll from Joyce for her birthday. Then the second, the third... the dolls never arrived late, year after year.“Why always a doll?” This question had been in Amy’s mind until one day her father gave the answer. Joyce dreamed of having a doll when she was a child herself. Her parents promised one for her fifth birthday. Sadly, they bothdied in a traffic accident before it arrived. The never—received gift was the most precious one in her eyes.Recalling(回想起) her mother’s story, Amy got an idea.It was Joyce’s 60th birthday. She go t a package with a card that read:Dear Joyce,I forget to send you a package that you should have received on May 20, 1956, your fifth birthday. The gift inside has aged, but I felt that you might still want to have it.Love,Angel of JoyJoyce opened the package and saw a lovely grandma doll. She clasped the doll that she had waited so many years for, with tears running down her face.
