问题     Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span. "I think we are knocking at the door of immortality (永生), "said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate (保守的估计)."
    At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology (纳米技术) make it likely that humans will bye in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years." However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
    Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology. Centre. "At present people who could get to that point are not in good health at all."  
What would be the best title for this text?
选项 A、Living Longer or Not
B、Science, Technology and Long Living
C、No Limit for Human Life
D、Healthy Lifestyle and Long Living
答案A
解析 这道题问这篇文章的题目会是哪一个，考查的是对文章主旨大意的把握。需要综观全文，A选项Living Longer or Not可以反映这篇文章的主旨，因为所有的讨论都是围绕这个主题展开的。若以B选项Science，Technology and Long Living“科学、技术和长寿”为题，文章讨论的应是这三者的关系。C选项No Limit for Human Life的意思是“人类的生命是无限的”，文章中并没有人持此观点。D选项Healthy Lifestyle and Long Living的意思是“健康的生活方式与长寿”，本文未涉及健康的生活方式的内容，因此不选。
