Why elephants rarely get cancer is a mystery that has confused scientists for decades. A study led by researchers at Huntsman Cancer Institute(HCI), at the University of Utah and Arizona State University may have found the answer.According to the results, elephants have 38 additional modified copies of a gene that encodes p53, a well-defined tumor suppressor(肿瘤抑制基因), as compared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for becoming cancerous. In isolated elephant cells, this activity is doubled compared to healthy human cells, and five times that of cells from patients with Li-Fraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants’ increased resistance to cancer.＂Nature has already figured out how to prevent cancer. It’s up to us to learn how different animals overcome the problem so we can adapt those strategies to prevent cancer in people,＂says co-senior author Joshua Schiffman, M.D., pediatric oncologist(儿科肿瘤医生) at Huntsman Cancer Institute, University of Utah School of Medicine.But Prof Mel Greaves, from the Institute of Cancer Research in London, says we should focus on why humans have such high levels of cancer. He pointed to the rise of unhealthy, cancer-causing behaviours, such as obesity and sunbathing. ＂You’ve never seen an elephant smoke!＂he added.According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent compared to 11 to 25 percent in people.1. Why are elephants less likely to get cancer than humans?A. Elephants are bigger than humans.B. Elephants have more p53 genes than humans.C. Elephants are not as clever as humans.D. Elephants eat more than humans.2. What can we learn from the text?A. More p53 genes contribute to resisting cancer.B. Elephants have less damaged cells in their bodies.C. A healthy human has only one working copy of p53.D. Patients with Li-Fraumeni Syndrome must get cancer in their lifetime.3. What’s Prof Mel Greaves’ attitude towards the discovery?A. Doubtful.B. Neutral.C. Critical.D. Favorable.4. What can we infer from the last paragraph?A. Elephants have longer life than people.B. There is no chance that elephants die from cancer.C. The rate of elephants dying from cancer is increasing.D. It was thought that elephants could get cancer more easily.1.B2.A3. A4.DIV. 完形填空(每小题1分，共20分)阅读下面的短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。
