原题：B2. Although most people wish to live long lives, attempting to significantly extend the average human life span would be a mistake. If achieved, this would place an enormous burden on resources, lowering the quality of life for everyone.
What if , by the end of this century, we could more than double average life-span to between 160 and 180? Given that possibility, these are the issues that should be thoroughly discussed and debated. At some point, the number of people may become so large that it exceeds the carrying capacity of the planet, making life miserable for the vast majority of humans (and impossible for other species), even sowing the seeds for our own destruction.
The quality of life for very old people may be severely diminished, if changing the boundaries of aging is not accompanied by reasonable health. Certain tissues and organs may deteriorate even as life-span is markedly prolonged, so people may live 140 years with ever –worsening sight, hearing, mental function, and musculoskeletal function. Meanwhile, we might be expected to work, support ourselves, and pay taxes until age 80, 90, 110 or older. Some of us will outlive our resources and spend our extended years live in poverty. This would likely create intense adversarial relations between younger and older persons as they compete for limited jobs and resources.

* 但报纸现在恐怕不是最重要的source of news了。Internet、mobile phone作为新闻的来源很可能已经超过了newspaper，它们方便、更新及时，而报纸顶多日刊，can’t provide latest news
