剑桥雅思6 Test 3 Passage 3阅读答案解析

第28题答案:NO

对应原文:第1段:As researchers on aging noted recently, no treatment on the market today has been proved to slow human aging

答案解析:原文中提到“目前市场上还没有任何治疗方案被证明能够延缓人类衰老”。而题干中则说现在已经存在延缓衰老过程的药物,与原文表达含义完全相反,因此判断为NO。

第29题答案:YES

对应原文:第1段:Those findings suggest that caloric restriction could delay aging and increase longevity in humans, too.

答案解析:原文中提到“这些发现表明限制热量摄入能够延缓人类衰老并延长寿命”。题干中的scientific evidence与findings对应,extend human life与increase longevity in humans对应,fewer calories是上文内容。即题干中的每个信文章来自老烤鸭雅思息点在原文中都有出现,由此确定答案为YES。

第30题答案:YES

对应原文:第2段:Few mortals could stick to that harsh a regimen, especially for years on end.

答案解析:原文中提到“很少有人能够坚持如此苛刻的方案,尤其是要好多年”。可见热量限制饮食毫无吸引力。由此判断答案为YES。

第31题答案:NOT GIVEN

对应原文:无

答案解析:虽然文中多次提到老年疾病,但从来都没有说过这些老年病跟饮食相关。因此判断答案为NOT GIVEN。

第32题答案:YES

对应原文:第3段:rats fed a low-calorie diet lived longer on average than free-feeding rats.

答案解析:原文中提到“喂养低热量饮食的老鼠比自由喂养的老鼠活的更长”。题干只是将这一说法反了过来,而ate what they wanted又与free-feeding对应,由此确定答案为YES。

第33题答案:A

对应原文:第6段:The caloric-restricted animals … they have more normal blood glucose levels (pointing to a reduced risk for diabetes

答案解析:原文中提到“热量摄入受限的动物血糖含量更加正常,患糖尿病的概率更低”。因此确定答案为A

第34题答案:B

对应原文:第6段:Further, it has recently been shown that rhesus monkeys kept on caloric-restricted diets for an extended time (nearly 15 years) have less chronic disease

答案解析:文中提到,热量受到限制的猴子患上长期疾病的可能性更低。反过来说,也就是热量不受限制的猴子患上长期疾病的可能性更高。

第35题答案:C

对应原文:第6段:They and the other monkeys must be followed still longer, however, to know whether low-calorie intake can increase both average and maximum lifespans in monkeys.

答案解析:原文含义为,所有的猴子都需要继续进行研究才知道低热量摄入能否增加平均寿命和最大寿命。也就是说目前还没有任何结果,因此确定答案为C。

第36题答案:A

对应原文:第6段:they have lower blood pressure and triglyceride levels (signifying a decreased likelihood of heart disease)

答案解析:根据题干中的heart disease定位到这一句,其中的they仍然是指代的热量摄入受限制的猴子,由此确定答案为A。

第37题答案:B

对应原文:第5段:compared with control animals that eat normally, caloric-restricted monkeys have lower body temperatures and levels of the pancreatic hormone insulin

答案解析:根据题干中insulin定位到第5段的这句话。原文中提到,热量受限制的猴子胰岛素水平较低。即不受限的猴子胰岛素水平更高,因此确定答案为B。

第38题答案:glucose

对应原文:第8段:By limiting food intake, caloric restriction minimizes the amount of glucose entering cells and decreases ATP generation.

答案解析:根据题干中下一行的producation of ATP is decreased定位到这句话,由此往前。发现minimize跟less对应,由此确定答案为glucose。

第39题答案:free radicals

对应原文:第8段: One possibility relates to the ATP-making machinery’s emission of free radicals, which are thought to contribute to aging and to such age-related diseases

答案解析:根据theory 1的标题定位到这一句,题干中emitted与空存在修饰关系,由此确定答案为free radicals。

第40题答案:preservation

对应原文:第8段:Another hypothesis suggests that decreased processing of glucose could indicate to cells that food is scarce (even if it isn’t) and induce them to shift into an anti-aging mode that emphasizes preservation of the organism over such ‘luxuries’ as growth and reproduction.

答案解析:根据theory 2定位到这一句话。focus on与emphasize同义替换,由此确定答案为preservation。
