Exactly where we will stand in the long war against disease by the year 2050 is impossible to say. (46)
But if developments in research maintain their current pace, it seems likely that a combination of improved attention to dietary and environmental factors, along with advances in gene therapy and protein targeted drugs, will have virtually eliminated most major classes of disease.
From an economic standpoint, the best news may he that these accomplishments could be accompanied by a drop in health-care costs. (47)
Costs may even fall as diseases are brought under control using pinpointed, short term therapies now being developed.
By 2050 there will he fewer hospitals, and surgical procedures will be largely restricted to the treatment of accidents and other forms of trauma. Spending on nonacute care, both in nursing facilities and in homes, will also fall sharply as more elderly people lead healthy lives until close to death.
One result of medicine’s success in controlling disease will he a dramatic increase in life expectancy. (48)
The extent of that increase is a highly speculative matter, but it is worth noting that medical science has already helped to make the very old (currently defined as those over 85 years of age) the fastest growing segment of the population.
Between 1960. and 1995, the U. S. population as a whole in creased by about 45%, while the segment over 85 years of age grew by almost 300%. (49)
There has been a similar explosion in the population of centenarians, with the result that survival to the age of 100 is no longer the newsworthy feat that it was only a few decades ago.
U.S. Census Bureau projections already forecast dramatic increase in the number of centenarians in the next 50 years: 4 million in 2050, compared with 37,000 in 1990.
(50)
Although Census Bureau calculations project an increase in average life span of only eight years by the year 2050, some experts believe that the human life span should not begin to encounter any theoretical natural limits before 120 years.
With continuing advances in molecular medicine and a growing understanding of the aging process, that limit could rise to 130 years or more.
选项
答案
虽然人口统计局预测到2050年之前人的平均预期寿命只增加8岁,但是一些专家认为,人们预期寿命可以达到120岁不会受到任何理论上的自然限制。
解析
句子的框架是Although…,some experts believe that…。although引导方式状语从句。主句中that引导的从句做believe的宾语从句。project此处译为“推断,预计”。
