In ancient (古老的) times the most important examinations were spoken instead of written. In the schools of ancient Greece and Rome, testing usually includes saying poetry aloud or giving speeches. In the European universities of the Middle Ages, those students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process (过程) of testing candidates (考生) for the doctor’s degree. Generally, however, modem examinations are written. The written examination, where all students are tested on the same question, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modem industry. A room full of candidates for a state examination, timed exactly by electric clocks and carefully watched over by managers, resembles (类似) a group of workers at an automobile factory. Generally, during examinations teachers and students are expected to act like machines. One type of test is sometimes called an "objective" (客观的) test. It is designed to do with facts, not personal opinions. To make up an objective test the teacher writes a series of (一系列的) questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like correct answers to students who have not learned the material properly. The kind of exams where students must select answers are ______.
This year, my husband Doug and I celebrated the 25th birthday of a man we had never met. His name was Tonny Horn. On the night of October 21, 2005, when he was standing in a parking lot (停车场) talking to friends, Tonny jumped to the top of a car, as he had done a hundred times before. This time, though, Tonny lost his balance (平衡). His head struck the ground, hard. All night, Elizabeth, Tonny’s mother, stood next to her son, who was lying in a hospital bed. She remembered that Tonny has once mentioned organ (器官) donation (捐献). Maybe I can spare another family this pain, she thought. When the time came, she and her husband Tom signed the forms permitting his organs to be taken out. Tonny was declared dead the next day. Twenty-four hours later, in a Boston hospital, Tonny’s liver (肝脏) was made part of my husband, Doug, who was suffering from a hopeless liver disease. Months later, we learned the Tonny’s parents wished to meet someone who had gained life through the gift from their son. A meeting was arranged by the organ bank to bring together the two families. The meeting was risky, but worth it. We learned for the first time how Tonny had lived and died. We learned something about Tom and Elizabeth too. For the Homes, seeing Doug and knowing he was well seemed to ease (减轻) their suffering. I’ll never forget seeing Doug’s tall figure stooped (弯腰) over Elizabeth, her arms around his waist, as a mother would hug (拥抱) a son. What helped to ease the Homes’ suffering

Computer programmer Kevin Hanley earns $100,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a check card. Instead he has been told to wait until he is 18. The 16-year-old boy works for a small firm in Pittsburgh, where the problem of most young people of his age is finding a job. Kevin’s firm releases (发布) two new games for the home computer market each month. But Kevin’s biggest headache is what to do with his money. Though Kevin earns a lot of money, he cannot drive a car, or buy a house, or obtain (获得) credit cards. He lives with ’his parents in Pittsburgh. His company has to pay $200 a month in taxi fares (费用) to get him five miles to work and back every day because Kevin cannot drive. "I got this job because the people who run the firm knew I had already written some programs," Kevin said. Most of Kevin’s spare time is spent working. "Unfortunately, computing was not part of our studies at school," he said, "But I had been studying it in books and magazines for years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young anyway." Kevin added, "I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear." Why does Kevin think he might retire early
