答案:B
原文定位:In mice many experiments had come to the same finding: feed them a diet with 30% fewer calories and see a lifespan extension of 40%. The monkey trials were set up a similar way: researchers took the calorie content of a standard monkey diet, cut it by 30% (while continuing to supply all essential nutrients) and monitored whether those monkeys lived longer, healthier lives than those on the standard diet
同义替换:「same level of calorie reduction」↔「cut it by 30%」
答案:G
原文定位:Indeed, Anderson points out that several of the NIA control monkeys have lived past the age of 40, far exceeding the 27-yea average lifespan for captive rhesus monkeys
同义替换:「higher age than normal」↔「far exceeding the 27-year average lifespan」
答案:E
原文定位:Second, whereas the Wisconsin monkeys were given highly processed food high in sucrose, making it easy to standardise, the NIA diet was based on whole grains, fish oils, and was very low in sugar. These different settings for the normal control diet may provide an explanation of why the two groups showed different results
同义替换:「distinctions between the types of food」↔「highly processed food high in sucrose」,「led to a contrast in findings」↔「why the two groups showed different results」
答案:C
原文定位:Compared to well-fed control animals, the lean monkeys were living longer and suffering less from the diseases of ageing: diabetes, heart disease and brain diseases
同义替换:「health problems」↔「diabetes, heart disease and brain diseases」,「less likely to get」↔「suffering less from」,「calorie-restricted diets」↔「calorie restriction」
答案:A
原文定位:Rozalyn Anderson;I find the idea monumentally unattractive
同义替换:「negative opinion」↔「monumentally unattractive」,「calorie-restricted diet」↔「calorie restriction」
答案:D
原文定位:The Wisconsin study began with monkeys in early adulthood
同义替换:「stage in the monkeys' lives」↔「early adulthood」,「research commenced」↔「began」
答案:Rozalyn Anderson
原文定位:The fact the two studies were set up differently, asking the same question in different ways I think we will gain maximally from that
同义替换:「dissimilar approaches」↔「in different ways」,「benefit」↔「gain maximally from that」
答案:Leonie Heilbronn
原文定位:However, neither group had the right notion of a standard diet according to Leonie Heilbronn, who researches calorie restriction and healthy ageing at the University of Adelaide in Australia. Heilbronn points out that the NIA controls were a very healthy set o monkeys and leaner than a control monkey should be. On the other hand, she notes, the Wisconsin controls were a little bigger than they had to be
同义替换:「study」↔「group」,「not typical」↔「had the right notion of a standard diet」
答案:Rozalyn Anderson
原文定位:We study it because it is so effective at delaying ageing and the onset of age-related disease. It's a way to tease out what it is that creates increased disease vulnerability as a function of age
同义替换:「method of finding out」↔「a way to tease out」,「health issues connected with ageing」↔「disease vulnerability as a function of age」
答案:Julie Mattison
原文定位:Julie Mattison, head of the NIA study, observes that an overweight person who goes to a fast food restaurant every day will obviously benefit if their calories are cut back by 30%
同义替换:「unhealthy diets」↔「fast food restaurant every day」,「positive effect」↔「will obviously benefit」,「calorie reduction」↔「calories are cut back by 30%」
答案:ageing
原文定位:Both studies agree that cutting calories is beneficial to health in both cases the calorie-restricted monkeys had fewer diseases related to ageing
同义替换:「associated with」↔「related to」
答案:lifespan
原文定位:As to the question of whether calorie restriction extends lifespan in primates, Anderson and Mattison are currently working together to compare the two studies' raw data
同义替换:「increase」↔「extends」
答案:conflict
原文定位:The current data conflict will ultimately provide deeper insights into ageing, Anderson predicts
