Making the news一、阅读理解。During the last decade the number of people living past 100 has increased by 71 percent. While one expert believed this figure will continue to rise, he stated that anyone hoping to live for double or triple(三倍) this time will be disappointed. Speaking at a conference, Colin Blakemore, 70, a British scientist, claimed there is a ceiling on how long humans can live, and six score years “might be a real absolute limit to human lifespan. ”A group of scientists discussed the future of medicine, global health concerns and life expectancy. It agreed that medicines will have a limited impact on extending human life, and it was more important to improve the health and quality of life for older people, rather than prolonging it. The group also stated it was important to improve the life expectancy in poorer areas where people typically die much younger than other areas. The 2014 Global Age Watch Index(全球年龄指数), which ranks 96 nations on the quality of life for the elderly, recently stated that by 2050, the number of over 60s will be 21 percent of the global population. This is almost double the current figure of 12 percent. The percentage of over 80s is growing fastest, tooexpected to rise from 2 percent now to 4 percent of the global population by 2050. While it could take years of research to extend humans lives, the study raises the possibility of anti-ageing treatments in a new way, according to Dr Kapahi. The research, reported in the journal Cell Reports, may explain why it has proved so difficult to identify single genes(基因) responsible for the long lives enjoyed by humans. “Its quite probable that interactions between genes are critical in those fortunate enough to live very long, healthy lives, ” said Dr Kapahi. Future research is expected to use mice to see if the same effects occur in mammals. 【文章大意】在过去十年里, 寿命达到100岁以上的老人的数量激增了71%。但是英国科学家柯林布雷克莫尔提出, 人类的寿命是有上限的, 而120岁很可能就是这个上限。1.
