5．A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse．
The paper，published this March in Psychology and Aging，examined health and welfare surveys from roughly 40，000 Germans between ages 18 and 96．The surveys were conducted every year from 1993 to 2003．
Survey respondents （受访者） were asked to estimate their present and future life satisfaction on a scale of 0 to 10，among other questions．
The researchers found that young adults （age 18 to 39）routinely overestimated their future life satisfaction，while middle-aged adults （age 40 to 64）more accurately predicted how they would feel in the future．Adults of 65 and older，however，were far more likely to underestimate their future life satisfaction．Not only did they feel more satisfied than they thought they would，the older pessimists seemed to suffer a lower ratio （比率） of disability and death for the study period．
"We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade，"wrote Frieder R．Lang，a professor at the University of Erlangen-Nuremberg．
Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future．
"Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions （预防措施），"the authors wrote．
Surprisingly，compared with those in poor health or who had low incomes，respondents who enjoyed good health or income were associated with expecting a greater decline．Also，the researchers said that higher income was related to a greater risk of disability．
The authors of the study noted that there were limitations to their conclusions．Illness，medical treatment and personal loss could also have driven health outcomes．
However，the researchers said a pattern was clear．"We found that from early to late adulthood，individuals adapt their expectations of future life satisfaction from optimistic，to accurate，to pessimistic，"the authors concluded．

分析 德国的一项研究表明，与悲观者相比，对自己的未来过于乐观的人在未来10年更容易出现残疾或死亡．该研究还发现，年轻人对自己未来生活的满意度的期望过高，中年人预测相对准确，而老年人往往低估自己未来生活的满意度．所以随着年龄的增长，对生活的期望也在下降．
解答 67．B 细节理解题．根据第四段的"while middle-aged adults （age 40 to 64）more accurately predicted how they would feel in the future．"可知，40～64岁的中年人组对自己未来生活的满意度估计更准确一些，故选B．
68．C 推理判断题．根据第六、七段的内容可知，郎和他的同事认为，对自己未来悲观的人比乐天派对自己的日常行为更小心，这样的人可能会采取预防措施，所以悲观在某种程度上可能是积极的，因为能让人们采取措施应对潜在的危险，故选C．
69．A 推理判断题．根据第八段的"…respondents who enjoyed good health or income were associated with expecting a greater decline…"可知，与身体不好、收入不高的人相比，身体好或者收入高的受访者往往预料自己这两方面（好身体或高收入）将来会下降得更厉害，所以高收入者认为自己将来的收入会少，故选A．
70．D 推理判断题．根据文章前几段提到不同年龄组对自己未来生活满意度的估计：年轻人太乐观，中年人较实际，老年人更悲观，可知，对未来生活满意度的期望是随着年龄而递减的，最后一段也有明确的提示，故选D．
点评 本文主要考查对细节的理解把握和推理判断能力，做题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
