Ⅱ.阅读理解A【2017·衡阳高三一模】There has been a controversy between animal rights supporters and scientists about whether it is right to use animals to find cures for human diseases in experimental research. Personally, if there are no other alternatives, and if it is possible that this will contribute to science, animals may be used for experimental research.The animal rights supporters label scientists as “cruel” for causing animals to die in medical experiments, while they do not oppose the people, mostly farmers, who kill animals for food. Some even claim that people and animals are equal and they should be treated equally. But can the death of an animal be the same thing as the death of a person? I think causing animals to die for science or for saving human lives may be considered ethical (伦理的), if it will contribute to the advancement of science and human health in general.Another basic argument of animal rights supporters is that people and animals are different genetically. They claim that it will make no good to use animals in experiments because they are too different to be compared to people. Some of them even state that it is better to use people directly as they think that the results of experiments on animals cannot be valid and reliable as long as the same observation has not been done on man. However, these people cannot foresee the disastrous results of such a practice. Many people are likely to die until a healthy result is obtained. People and animals may not be the same, but to some degree, scientists are right to use animal models to do some experiments that could not be achieved in human. There are also a lot of examples which show that using animals resulted in significant developments and helped to cure some serious illnesses.All in all, using animals for medical research is ethical as long as it contributes to scientific development and human health. And this practice is only acceptableon the condition that animals are treated humanely.语篇解读：本文是一篇议论文，主要论述了动物权利支持者和科学家之间关于用动物进行医学试验研究以寻找治疗人类疾病的方法是否正确的争议。

BPeople have been wondering why elephants do not develop cancer even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) developing. To be precise, they found 20 copies of an antitumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.According to the research, the extra copies of the gene improved the animal's sensitivity to DNA damage, which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.“An increased risk of de veloping cancer has stood in the way of the evolution of large body sizes in many animals，” the study author Dr. Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous (癌变的), large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice. But across species, the risk of cancer does not show a connection with body mass.This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto's paradox (悖论)”. Biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancer spreading or even developing in the first place.“Natu re has already figured out how to prevent cancer，” said Joshua Schiffman, a biologist at the School of Medicine, University of Utah, US. “It's up to us to learn how different animals deal with the problem so that we can use those strategies to prevent canc er in people.”语篇解读：科学家研究发现，大象不患癌症是因为它们的体内有很多阻止肿瘤生长的基因TP53，人类有望通过研究TP53来预防癌症。
