But why do people read newspapers?Five hundred years ago, news of important happenings —battles lost and won, kings or rulers overthrown or killed — took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in ournewspapers of important events that occur in far away countries on the same day they happen.Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories, and of course, advertisements. The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money for news of their products to go into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit.1. The phrase “subscribe to” in the first paragraph means .A. go to the newspaper stand and buyB. send their own news stories toC. agree to buy for a specific period of timeD. become faithful readers of2. The habit of reading newspapers is .A. widespreadB. found among a few familiesC. not popularD. uncommon3. Before the time of the newspaper, .A. bad news traveled quickly and good news slowlyB. few people cared about events that took place in far away countriesC. kings and rulers were often overthrown or killedD. news was passed from one person to another4. The author seems to agree that money spent on advertisements is .A. wastedB. not muchC. well spentD. of no use to anyone5. Which of the following statements is true?A. Five hundred years ago it took a long time for news to reach other countries.B. Newspaper advertisements turn people’s attention away from their products.C. The news that we read in newspapers is mainly about new products.D. When newspapers are sold at a low price, the newspaper producers will lose money.Passage 2When John and Victoria Falls arrived in New York City for one-year stay, they did not bring very many things with them. They had planned either to live in a furnished apartment or to buy used furniture. But they soon learned about a new system that more and more people are using. The renting of home furnishings (bed, tables, dishes, and so on) has become one of America’s fastest growing businesses.What kinds of people rent their home furnishings instead of buying them? People who are international businessmen or government officials, foreign students, airline workers, young married couples — people whose job or business may force them to move frequently from one city to another. They save a lot of trouble and the cost of moving their furniture each time. They simply rent new furniture when they reach their new homes. Young people with little money do not want to buy cheap furniture that they may soon dislike. They prefer to wait until they have enough money to buy furniture they really like. Meanwhile, they find they can rent better qualityfurniture than they could afford to buy.One family, who now have a large, beautiful home of their own, liked their rented furniture so much that they decided to keep renting it instead of buying new things. But usually people do n’t like to tell others about it. The idea of renting home furnishings is still quite new, and they are not sure what their neighbors might think.6. Which of the following has become one of America’s fastest growing businesses?A. Selling home furnishings.B. Renting furnished apartments.C. Selling used furniture.D. Renting home furnishings.7. Why do some people prefer to rent furniture?A. Because the furniture they get in this way is new.B. Because it saves them a lot of money.C. Because it saves them much trouble and money.D. Because they can always get better quality furniture in this way.8. What can you infer from the passage?A. The idea of renting furniture is not acceptable.B. Renting furniture is still not popular with the majority of Americans.C. Only those who don’t have enough money rent furniture.D. People usually grow to like the furniture they have rented.9. Which of the following can best serve as the title of the passage?A. Rent or Buy?B. A New Way of Getting Home FurnishingsC. Furnished ApartmentsD. A New Idea10. Young people like renting home furniture in that_________A. They have less money.B. They don’t want to buy old furniture.C. The new furniture is of good quality.D. They don’t have much money and don’t want to buy the cheap furniture.Passage 3Spending 50 minutes with a cell phone close to your ear is enough to change brain cell activity in the part of the brain closest to the antenna(天线). But whether that causes any harm is not clear, scientists at the National Institute of Health said at a conference last month, adding that the study will not likely settle concerns of a link between cell phones and brain cancer. “What we showed is glucose (葡萄糖) metabolism(代谢)(a sign of brain activity) increases in the brain in people who were exposed to a cell phone in the area closest to the antenna,” said Dr. Nora Volkow, whose study was published in the Journal of the American Medical Association. The study was meant to examine how the brain reacts to electromagnetic(电磁的) fields caused by wireless phone signals.Volkow said she was surprised that the weak electromagnetic radiation(辐射) from cell phones could affect brain activity, but she said the findings do not shed any light on whether cell phones cause cancer. “This study does not in any way indicate that. What the study does is to show the human brain is sensitive to electromagnetic radiation from cell phone exposures.” Use of the devices has increased dramatically since they were introduced in the early 1980s, withabout 5 billion cell phones now in use worldwide.Some studies have linked cell phone exposure to an increased risk of brain cancers, but a large study by the World Health Organization did not of fer a clear answer to this. Volkow’s team studied 47 people who had their brain examined while a cell phone was turned on for 50 minutes and another while the phone was turned off. While there was no complete change in brain metabolism, they found a 7 percent increase in brain metabolism in the region closest to the cell phone antenna when the phone was on.Experts said the results were interesting, but urged that they be understood with great care. “Although the biological significance, if any, of increa sed glucose metabolism from too much cell phone exposure is unknown, the results require further investigation,” Henry Lai of the University of Washington in the U.S. and Dr. Lennart Hardell of University Hospital in Sweden, wrote in an article in JAMA. “Much has to be done to further investigate and understand these effects.” They wrote.11. According to the passage, which of the following is TRUE?A. Cell phone use is dangerous.B. Cell phone use causes cancer.C. The human brain is an electromagnetic field.D. There are about 5 billion cell phone users in the world right now.12. Doctor Volkow was astonished because ______.A. her research has shed light on her understanding of cell phoneB. she found that cell phone exposure is harmful to human brainC. she found that using a cell phone for about 50 minutes could influence or change brain activityD. human brain is not responsive to electromagnetic radiation13. According to the passage, cell phones were launched _______。
