单选题 Technology is the application (应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available (可供食用的) to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via (通过) medical technology. Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it wisely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics (统计) show that the united States is continuing to pump billions of dollars annually (每年) into such efforts. So while we are running out of some scarce resources (稀缺资源) we may well find technological substitutes (代用品) for many of them through our research programs. Therefore, in the final analysis the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.

单选题Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 41 through 45.For each question or statement there are 4 choices marked A) , B) , C) and D) . You should make the correct choice and mark the corresponding letter on the Answer Sheet with a single line through the center. One silly question I simply cannot bear is "How do you feel'?." Usually the question is asked of a man in action -- a man walking along the street, or busily working at his desk. So what do you expect him to say`?. He' ll probably say, "Fine, I' m all right. " But you have put a bug in his ear -- maybe now he is not sure. If you are his good friend, you may have seen something on his "face, or in his walk, that he overlooked that morning. It makes him worrying a little. He looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else, "How do you feel'?." Every question has its time and place. It's perfectly acceptable, for example, to ask "How do you feel,?" if you are visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to take a train or sitting at his desk working, it's no time to ask him that silly question. When George Bernard Shaw, the famous British writer of plays was in his eighties, someone asked him, "How do you feel?" Shaw put him in his place. "When you reach my age," he said, "either you feel all right or you are dead. "

单选题About one in twenty adults in the United States cannot read English. A new federal study shows that adults made little progress in their reading skills between 1992 and 2003. The National Assessment of Adult Literacy is the most important test of how well adult Americans can read. Researchers tested nineteen thousand people over the age of sixteen. The study represents an adult population of two hundred twenty-two million. Those who took part were tested on how well they could read and understand information used in everyday life, The study found that eleven million adults, or five percent, cannot read English. They could not answer even the easiest written questions. Four million of them most likely cannot speak English either. The study shows that more than forty percent of adults can perform only simple reading activities. For many, even that can be difficult. Fifty-six percent of adults can perform moderate or complex activities. Moderate can mean finding information in a book. Of that number, thirteen percent can perform complex tasks like comparing two different newspaper commentaries (评论). Researchers say part of the problem is that many young Americans do not read as much for pleasure anymore. Also, there are greater numbers of non-English speaking immigrants. Reading skills can directly affect the ability to earn a living. The best readers were found to earn up to twenty-eight thousand dollars a year more than those who lacked simple reading skills. Yet, compared to the last study in 1992, adults" reading skills were about the same or lower across every level of education. This was true even among people who have completed college. By race and ethnic group, blacks and Asians had the biggest increases in English reading skills. But levels decreased among Hispanics. Experts, say, however, that while many Hispanics are unable to read in English, they may read well in Spanish. Overall, American adults improved the most in answering questions that involved numbers. Even so, the test found that the average adult cannot do much more than perform simple, everyday math.

单选题Do you know how to use a mobile phone without being rude to the people around you? Talking during a performance irritates (激怒) people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate (振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance. Think twice before using mobile phones in elevators, museums, churches or other indoor public places—especially enclosed spaces. Would you want to listen to someone"s conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral! It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off. When eating at a restaurant with friends, don"t place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you. Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won"t hear the details of your conversations. If you are calling from a noisy area, use your hand to direct your voice into the microphone. Many people believe that they can"t live without their mobile phone. Owning a mobile phone definitely makes life more convenient, but limit your conversations to urgent ones and save the personal calls until you are at home.
