[1] Have you ever had the wish to live another 100 years or more? Experts say that scientific advances will some day enable us to live tens of years longer than what is now seen as the natural limit of the human life span.
[2] “I guess we are knocking at the door of living longer,” said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will            _________________ and that’s a conservative estimate (保守的估计)."
[3]At the conference in San Francisco, Donald Louris, 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 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.
[4]However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to live 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.
[5]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 a good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."

Answer 1

小题1:Scientific advances will enable humans to live longer.
小题2:reach / achieve/ accomplish that goal 
小题3:Advances in using genes as well as nanotechnology.
小题4:Whether people can live from 120 to 180 years.
小题5:Whether we could be healthy enough to have a good quality of life.

试题分析：文章大意：科学家说先进的科学技术可以让人的寿命得到延长。
小题1:细节题，根据文章第一段第二句Experts say that scientific advances will some day enable us to live tens of years longer than what is now seen as the natural limit of the human life span.可以归纳出答案。
小题2:归纳题。根据前后句可以归纳出这里为“实现目标”这个短语，从而可以得出答案。
小题3:细节题。根据文章第三段At the conference in San Francisco, Donald Louris, 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 live in the future beyond what has been possible in the past.，故可以归纳出答案。
小题4:推理题。根据文章上一段中的There is a great push so that people can live from 120 to 180 years可以归纳出答案。
小题5:细节题。根据文章最后一段you know; could you be healthy enough to have a good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."从而可以归纳出答案。
