11、练.阅读理解People have been wondering why elephants do not develop cancer even though they have lifespans 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 has found that elephants carry a substantial number of genes tha
12、t stop tumors developing. To be precise, they found 20 copies of an anti-tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.According to the research, the extra copies of the gene improve the animals sensitivity to DNA damage, which lets the cells quickly
13、kill themselves when damaged before they can go on to form deadly tumors.“An increased risk of developing cancer has stood in the way of the evolution(进化) 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
14、cancerous, large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and rats. 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 th
15、e 1970s and later named “Petos paradox”. Biologists believe it results from larger animals using protection that many smaller animals do not use. In the elephants case, the making of TP53 is natures way of keeping this species alive.The study also found that when the same genes were brought to life
16、in rats, 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.“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, a biologist at
17、the School of Medicine, the University of Utah. “Its up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people.”1.Why are elephants unlikely to develop cancer?A.They have a rather large body size.B.Their genes suffer no DNA damage.C

20、ncluded from the passage?A.Depending on nature is surely enough to fight against cancer.B.The TP53 genes have proved useful in stopping cancer in people.C.Humans are expected to prevent cancer with the making of TP53.D.The extra copies of elephants genes are used to cure cancer patients.七选五Leonardo
21、da Vinci and NatureIn the modern world, art and science are two dramatically separate activities, but in Leonardos time they were closely connected. Science meant mathematics and medical studies. 1 Mathematics included practical work like surveying land for making maps as well as measuring the movem
22、ents of the stars in the sky. An artist might need to measure the different parts of the body. He could also use mathematics to place things in relationship to each other in a drawing or painting so the scene looked correct. 2Mathematics is also connected to music because musical sounds have a fixed
23、 relationship with each other that can be described in numbers. 3 More than this, though, Leonardo believed that numbers were a part of all things in the world, including music, and he said that “without them nothing can be done”.“Mysterious nature has kindly given us things everywhere to copy,” wro
