Do you want to live another 100 years or more? Do you want to live never to die? Some experts say, it will be not a dream one day. Modern technology will make it come true. Man will live more years beyond what is now seen as the natural limit of the human life. “ I think we are knocking at the door of immortality, ” said Michael, a professor and author of two books on human life expectancy. “I think by 2075 we will see it and it’s no longer a dream. Human’s life expectancy may have not limit.” At the meeting in San Francisco, Donald Louria, a professor at New Jersey Medical School said advances in using genes as well as other technology make it likely that humans will live 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 300 or 500 years.” However, many scientists are doubtful about it and say the human body is just not designed to last more than about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and other parts of the body will finally lead all humans to death. Scientists also hold different opinions on what kind of life man might live.  “If you pass 120, you know; could you be healthy enough to have good quality of life? It’s a big question.” said Leonard Poon, director of the university center.  “At present people who could get to that point are not in good health at all.” 小题1:The underlined word in the second paragraph probably means _____.
