英美报刊节选翻译练习(十七)

From < Eat less, live more> 摘自《经济学人》 Apr 20th 2006

DIETING, according to an old joke, may not actually make you live longer, but it sure feels that way. (1)Nevertheless, evidence has been accumulating since the 1930s that calorie restriction—reducing an animal's energy intake below its energy expenditure—extends lifespan and delays the onset of age-related diseases in rats, dogs, fish and monkeys.Such results have inspired thousands of people to put up with constant hunger in the hope of living longer, healthier lives. (2)They have also led to a search for drugs that mimic the effects of calorie restriction without the pain of going on an actual diet.

（1）Nevertheless, evidence has been accumulating since the 1930s that calorie restriction—reducing an animal's energy intake below its energy expenditure—extends lifespan and delays the onset of age-related diseases in rats, dogs, fish and monkeys.
然而，从20世纪30年代开始，不断累计的证据表明卡路里限制（使动物摄入的能量低于其能量消耗）可以延长寿命，并可以降低老鼠、狗、鱼和猴子身上与年龄相关的疾病的发病率。

（2）They have also led to a search for drugs that mimic the effects of calorie restriction without the pain of going on an actual diet.
这些结果也引发了对既能模拟卡路里限制的效果又能免受真的节食带来的痛苦的药物的探索。
