Passage Two
There were many different cultures in the ancient world, but the two that had the most influence on European and American civilizations were the Greek and the Roman.Often these two cultures are lumped together in our minds, as if they were really exactly alike. But that is not the case. In many ways the Greeks and the Romans could not have been more different. The Greeks were truly democratic, often without a single leader but instead governed by a group of men chosen by the people. The Romans were semi-democratic. They had a governing Senate, but the political power was mostly or completely in the hands of a single emperor.
Both cultures were great builders. But the construction interests of the two cultures were also different. The Greeks tended to be more artistic. Their buildings were well constructed and they were especially interested in temples, columns, and decorative forms. The Romans, on the other hand, were more engineers than artists. They concentrated their efforts on urban planning, well-functioning water pipes, and the best roads.
Only in cooking and eating habits are the two cultures really similar. Both peoples ate very well indeed: lots of fish, fresh vegetables and fruits, healthy meals, holding at the same time long discussions and tasting excellent wines. In fact, it would probably be fair to say that they both loved life in their warm,sea-oriented climates and they both lived a full life.
40. What is the first paragraph about?
A. The Greek and the Roman were similar.
B. People misunderstood European civilization.
C.Greek civilization was quite different from Roman civilization.

B. The artistic decoration of the buildings.
C. The practical functions of the buildings.a
D. The system of water supply and transportation.
43. How are the two cultures alike?
A. Both loved the sea.
B. Both lived long lives.
C. Both loved cooking
D. Both enjoyed talking over meals.
Passage Three
As recently as three decades ago, many Americans believed that using credit was an unwise and dangerous way to pay for what they bought. Some even thought that owing money to a store or a credit company was something to be ashamed of. Good citizens, they believed, always bought what they wanted with real money and they paid the full price immediately.
Today,however,all that has changed.Credit,as some observers have noted, has become a way of life in the United States. More and more Americans now are depending on those small pieces of plastic, credit cards, to pay for large purchases such as televisions, record players or furniture. Many people today would consider it unusual not to use a credit card to pay for a costly restaurant dinner, a hotel room or an airline trip. And there are some situations in which Americans must have credit cards. If they want the temporary use of a car, for example, they first must give the car rental company the number of their credit card. That number is considered a guarantee that they will return the car and pay Credit cards offer two major services to Americans. First of all, they are easier and safer to carry than large amounts of money. Second, they permit people to borrow, to have the immediate pleasure of owning something, even if they do not have enough money to pay for it at the time. With credit cards people pay for goods or services at the end of each month
instead of when they buy them. And when the time does come to pay, most credit cards offer people a choice. They can pay all of what they owe for the month or they can just pay usually between 5 and 10 percent of what they owe.
44. What do Americans feel about using credit cards nowadays according to the passage?
A. They consider it valuable.
B. They regard it as a shame.
C. They think it dangerous.
D. They find it quite convenient.
45. Why does the car rental company ask for the credit card number?
A. To prevent the overuse of the car.
B. To make sure that the car won't be damaged.
C. To make sure the user return the car and pay for using it.
D. To ensure that the car is safely and timely returned.
46. What advantage can credit card holders have?
A. They can choose not to pay for their purchases.
B. They can easily borrow money at a lower interest.
C. They can own something before they actually pay for it.
D. They can pay only a small amount of what they owe.
47. What is the best title for the passage?
A. Credit-a Way of Life in America
B. Credit Services in America
C. Convenience of Living in America
D. History of Credit Cards in America
Passage Four
At the 1893 Columbian Exposition, a World Fair held in Chicago, chocolate-making machinery made in Germany was displayed. It caught the eye of M. S. Hershey, who saw the potential for chocolate. He installed chocolate machinery in his factory in Lancaster, and produced his first chocolate bars in 1894.
Other Americans began mixing in other materials to makeup new candy bars throughout the end of the 1890's and the early 1900's. But it was World War I that really brought attention to the candy bar.
The U. S. Army Quartermaster Corps requested various American chocolate manufacturers to provide 20 to 40 pound blocks of chocolate to be shipped to quartermaster bases. The blocks were cut into smaller distributed to American soldiers in Europe. Eventually the task of making smaller pieces was turned back to the manufacturers. By the end of the war when the soldiers arrived home, the American candy bar business was assured. Why?Because the returning soldiers had grown fond of chocolate candy and wanted more of the same. As a result from that time on and through the 1920's, candy bar manufacturers became established throughout the United States, and as many as 40, 000 different candy bars appeared on the scene.
The original candy bar industry had its start on the eastern coast in such cities as Philadelphia, Boston, and New York. The industry soon spread to the Midwest because shipping and raw materials such as sugar, corn syrup, and milk were easily available. Chicago became the seat of the candy bar industry and is even today an important base.
48. Why did M. S. Hershey start the production of chocolate bars?
A. He was deeply impressed by the Columbian Exposition.
B. He realized that it was possible for chocolate to become popular
C. There was nothing to produce in his factory in Lancaster.
D. He was interested in the chocolate machinery displayed at the fair

B. The demand in the army during WWI.
C. The purchase of new machines
D. The appearance of smaller candy bars.
50. What does the underlined word "seat"in the last paragraph most probably mean?
A. Focus. B. Position. C. Chair. D. Center
51. What is this passage mainly about?
A. World Fair held in Chicago in 1893.
B. The popularity of the American candy bar industry.o
C. The candy bar industry during World War.
D. The spread of the candy bar business to the Midwest.
Passage Five
Mark Twain is one of America's much-beloved authors, creating imaginative and humorous classics for children and adults alike, such as The Adventures of Tom Sawyer, The Prince and The Pauper,and Adventures of Huckleberry Finn.
Twain passed away in 1910, leaving behind a treasure of great literature. But now, 100 years after his death, he'll have a brand-new book on the shelves: a three-volume autobiography. Twain hasn't been keeping busy in his tomb it was his wish that publishers wait until 100 years after his death to publish his memoirs ) which he spent the last decade of his life working on.
The autobiography totals more than 5,000 pages, and likely won't be all sunshine and roses. It seems that Twain harbored some bitterness against former girlfriends and ex-friends. He also writes negatively about politicians of his day, such as Teddy Roosevelt. It's likely that he requested such a long lead time for the memoirs because he didn't want to hurt the feelings of anyone mentioned in this work.
Although small sections of the memoirs have been previously published the autobiography has never been available in full, and should provide great insights into the man behind the classic books. The first volume of the set will be available in November, and the trilogy is being published by the University of California, Berkeley.
"There are so many biographies of Twain, and many of them have used bits and pieces of the autobiography", editor Robert Hirst told The Independent. "But biographers pick and choose what bits to quote. By publishing Twain's book in full we hope that people will be able to come to their own complete conclusions about what sort of a man he was."
52. According to Paragraph 1, which of the statements is TRUE of Mark Twain?
A. He left behind lots of money.
B. His works were written for children.
C. His works are full of adventures.
D. He is famous for his great works.
53. What can we learn about Mark Twain's autobiography from the passage?
A. It has been published against Twain's will.
B. It shows Twain's respect for politicians.
C. It will be published in full.
D. It has been recently finished.
54. What does the underlined word "trilogy" in Paragraph 4 mean?
A. work in three volumes.
B. An imaginative work.
C. collection of stories.
D. Memoirs of famous people.
55. What is the purpose of publishing Twain's autobiography?
A. To supplement other biographies.
B. To help readers to understand Mark Twain.
C. To introduce Mark Twain's works.
