service in a residential home for people with learning disabilities. it was set in an english village deep in the countryside, quite different from my home in sweden. one of my fellow volunteers, a girl from tanzania, seemed a little unhappy, so i asked what the problem was. she told me she had a friend back home who had financial difficulties and maybe it was impossible for her to complete her university courses.so this friend of mine had sent all her money to tanzania to support her friend! this meant that she didnt have much food to eat and no money to go anywhere outside the village.i was so touched and i felt i had to do something. so, during my next trip to one of the nearby towns i walked into a shop. i didnt have much money left myself but i thought id buy her an extra box of chocolate we both liked and some rice. i started talking to the woman(also a volunteer)working in the shop and eventually told her about my friend.the woman looked at me, amazed. “does she eat pasta?” she asked. “yes,” i replied. she immediately started loading a bag with pasta, cookies, and other things until the bag was full. “give her this for me. its my treat! i couldnt believe it but accepted with happiness. as i left the shop to go home with my unexpected bag of food, i asked the woman her name. “just gloria,” she said.imagine my friends face when i arranged the gifts on my kitchen table and fetched her from her room to see! i had never seen her so happy! a few weeks later she found gloria in the shop and thanked her in person.these two extraordinary women really showed me what true kindness and compassion(同情)are, and the impression will stay with me for the rest of my life!36. the underlined word “it” in paragraph 1 probably refers to .a. the shopb. the writers homec. the residential home d. a year of voluntary service37. why did the girl from tanzania seem a little unhappy?a. because her friend in tanzania maybe had to quit school for lack of money.b. because she had spent all her money on food and clothes.c. because she had no money to buy food or other things.d. because she had to stop her voluntary work.38. why did the writer help the girl from tanzania?a. because the writer was a volunteer.b. because they lived in the same room.c. because the writer was moved by her kind act.d. because the writer didnt wish she went hungry.39. from the text, we know that .a. the writer was from englandb. the writer was a university student from tanzaniac. gloria was from sweden and was very kind to the writerd. the writer volunteered to help people with learning disabilitiesbfrom musician and philanthropist(慈善家)peter buffett comes a warm, wise, and inspirational book that asks, which will you choose: the path with least difficulty or the path of potentially greatest satisfaction?you may think that with a last name like his, buffett has enjoyed a life of endless advantages. but the son of billionaire warren buffett says that the only real thing handed down from his father was: build your own path in life. it is a principle that has allowed him to follow his own interests, establish his own identity, and gain his own successes.in life is what you make it, buffett describes the strong set of values given to him by his broadminded mother, his hardworking and talented father, and the many life teachers he has met along the way.todays society, buffett believes, has changed a lot. people begin to enjoy what they do, with a wealth ethic(财富伦理), honor the payoff instead of the process. yet, by focusing less on reward, we can open doors of opportunity and work hard toward a greater sense of satisfaction.in clear and brief terms, buffett explains a great truth: life cannot be predicted and doesnt have a second chance, neither fair nor unfair. we see that our journey in life seldom follows a straight line but is often met with false starts, difficulties, and mistakes. how we push through and dont give up at these challenging moments is where we begin to create the life of our dreams from discovering our careers to giving back to others.personal and instructive, life is what you make it is about challenging your condition, taking control of your own life and living it to the fullest.40.what does peter buffett value most about his mother?a. intelligence.b. independence.c. hard work.d. broadmindedness.41.which proverb can best

actually work more efficiently, and exert more effort, to achieve those goals.what are far less understood by scientists, however, are the potentially harmful effects of goal-setting. there has been surprisingly little research on how the practice may have contributed to the current economic crisis and unethical (不道德)behavior in general.“goals are widely used and promoted as having really beneficial effects. and yet, the same motivation that can push people to exert more effort in a constructive way could also motivate people to be more likely to engage in unethical behaviors,” says maurice schweitzer, an associate professor of operations and information management at penns wharton school. his paper, titled “goals gone wild: the systematic side effects of over-prescribing goal setting,” appears in the february issue of the academy of management perspectives.“it turns out theres no economic benefit to just having a goal-you just get a psychological benefit and thats quite motivating in itself,” schweitzer says. “but in many cases, goals have economic rewards that make them more powerful.”a prime example schweitzer and his colleagues give is the 2004 closing down of energy-trading titan(巨头)enron, where managers used financial rewards to motivate salesmen to meet specific sales goals. the problem, schweitzer says, is the actual trades were not earning money. other studies have shown that pressing employees with unrealistic goals can force them to lie, cheat or steal. such was the case, schweitzer says, in the early 1990s when sears imposed a sales target on its auto repair staff. it resulted in employees overcharging for work and completing unnecessary repairs on a companywide basis.schweitzer admits his research run against a very large body of literature that praises the many benefits of goal-setting. edwin a. locke, from the university of maryland, college park, and gary p. latham, from the university of toronto, write: “goal setting is not going away. organizations cannot develop without being focused on their desired results any more than an individual can develop without goals to provide a sense of purpose.”the debate is likely to be popular on in future papers, and the practice of setting goals no doubt will continue. for now, though, the lesson seems to be to put more thought into setting goals. “they really do help to coordinate and motivate people. my idea would be to combine that with careful observation, a strong organizational culture, and make sure the goals that you use are going to be constructive and not significantly harm the organization,” schweitzer says.48. what message does the author try to get across about goal-setting?a. its role has been largely underestimated.b. the goal increase peoples work efficiency.c. its negative effects have long been ignored.d. the goal most people set are unrealistic.49. what does maurice schweitzer want to show by giving the example of enron?a. goals with financial rewards have strong motivational power.b. businesses are less likely to succeed without setting realistic goals.c. financial rewards ensure companies meet specific sales goals.d. setting realistic goals can turn a failing business into success.50. how did sears goal-setting affect its employees?a. they were forced to work more hours to increase their sales.b. they competed with one another to attract more customers.c. the improved their customer service on a company wide basis.d. they turned to unethical practice to meet their sales target.第ii卷 (共55分)第一节 任务型阅读(共10小题,满分10分)blood
