問題詳情
請依下文回答第 33 題至第 36 題 Science can be a little scary. Its potential to transform life itself has led to predictions that we mightrewrite our own genetic make-up or merge our minds with machines. More and more drugs developed totreat disease are turning out also to push human life expectancy much further, perhaps to 115 years andbeyond. In the past, scientists had predicted that life expectancy could nowhere pass 78 years in 1952, 79years in 1980, and 82.5 years in 1984. However, the rapid scientific development has overturned theseprevious predictions.Scientists now know that cutting back severely on calories in the diet can give life expectancy aremarkable boost—between 30% to 50%—in a range of animals. This result makes lengthening human’s lifewith a giant leap possible. Now evidence is emerging that certain drugs may provide the benefits of calorierestriction without the pains of the diet. Life-extension enthusiasts who have been eating just 1,800 calories aday for an average of six years (a healthy Western diet averages 2,700 calories a day) do indeed show signsthat their bodily aging is slowing. Eating far fewer calories does not simply slow metabolism, nor do theadvantages come just from being thin, as aggressive calorie-burning exercise does not confer the samebenefits. Rather, calorie restriction appears to trigger natural defenses designed to boost the chance ofsurvival during periods of food scarcity.

(B) It allows humans to enjoy immortality in the near future.
(C) It makes effective calorie-burning an impossible task.
(D) It allows machines to be merged with human minds.
