Passage 2 Like many of my generation, I have a weakness for hero worship. At some point, however, we all begin to question our heroes and our need for them. This leads us to ask: What is a hero? Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people. A hero does something worth talking about. A hero has a story of adventure to tell and a community who will listen. But a hero goes beyond mere fame. Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people. The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve? What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant? Heroes are catalysts for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr., we might still have segregated buses, restaurants, and parks. It may be possible for large-scale change to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless. 6. Although heroes may come from different cultures, theyA. generally possess certain inspiring characteristicsB. probable share some weaknesses of ordinary peopleC. are often influenced by previous generationsD. all unknowingly attract a large number of fans

Passage 3 It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory usually has already started. Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities. Denise Park led the new study. She directs the Center for Aging and Cognition at eh Institute for Social Research at the University of Michigan. Her team studies more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems. She says young adults do not know they are forgetting things because their brains have more information than they need. But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies. Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information. The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false. Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use fro different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She says older people should take part in activities that keep their brain active. These include being a member of a book-reading club, seeing and discussing plays and concerts and playing games that use the mind. She hopes future studies will identify ways to improve the operation of our aging mind. 11.The passage is meant to __________________________A. emphasize the importance of exercising the brainB. analyze the difference between different age groups in the loss of memoryC. introduce effective ways to improve memoryD. reveal the decrease in mental ability of the young adults as well as the older adults
