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, too—expected 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. “It’s 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.
