28、ed risks for many types of cancer. At the same time, exercise involves biological stress, which typically leads to a short-term increase in inflammation(发炎)which can contribute to higher risks for many cancers.Now, a new study in mice may offer some clues into the exercise-cancer paradox. It suggest

29、s that exercise may change how the immune system deals with cancer by boosting adrenaline(肾上腺素), certain immune cells and other chemicals that, together, can reduce the severity of cancer or fight it off altogether.To try to better understand how exercise can both elevate inflammation and simultaneo

30、usly protect the body against cancer, scientists at the University of Copenhagen in Denmark and other institutions decided to closely examine what happens inside mice at high risk for the disease.So, for the new study, they began by gathering a group of adult lab mice. These animals generally like t

31、o run.The scientists then implanted melanoma (黑素瘤) skin cancer cells into the mice before providing half of them with running wheels in their cages while the other animals remained sedentary. After four weeks, far fewer of the runners had developed full-blown melanoma than the sedentary mice and tho

32、se that had been diagnosed with the disease showed fewer and smaller lesions.They drew blood from both the exercising and sedentary animals and cells from any tumors in both groups. As expected, they found much higher levels of the hormone adrenaline in the blood of the exercising animals, especiall

33、y right after they had been working out on the wheels but also at other times of the day. The body releases adrenaline in response to almost any type of stressful experience, including exercise.They also found higher levels of interleukin-6 in the blood of the runners. This is a substance that is re

34、leased by working muscles and is believed to both increase and decrease inflammation in the body, depending on where and how it goes to work.Perhaps most important, they found much higher numbers in the bloodstreams of runners than in the sedentary mice of a type of immune cell named natural killer

35、cells that are known to be strong cancer fighters.So the scientists repeated their original experiment multiple times, inducing cancer while allowing some mice to run and others to sit. In some of these follow-up experiments, the scientists injected the runners with a substance that blocked the prod

36、uction of adrenaline and gave sedentary animals large doses of added adrenaline.What they now found was that when running mice could not produce adrenaline, they developed cancer at the same rate as the sedentary animals, while the sedentary animals that had been injected with extra adrenaline fough

37、t off their tumors better than other sitting mice.More remarkably, the scientists determined that adrenaline seemed to be sending biochemical signals to some of the animals IL-6 cells, making them physiologically more alert, so that when a tumor began to develop in the affected animal, those IL-6 ce

38、lls in turn activated the natural killer cells in the bloodstream and actually directed them to the tumors, like minute guide fish.With these results, “we show that voluntary wheel running in mice can reduce the growth of tumors, and we have identified an exercise-dependent mobilization of natural k

39、iller cells as the underlying cause of this protection,” said Pernille Hojman, a researcher at the University of Copenhagen who oversaw the new study. It perhaps provides one more incentive for us to get up and move.8. The relationship between exercise and cancer has long puzzled oncologists and exe

40、rcise physiologists because _.A. exercise is strongly associated with lowered risks for many types of cancerB. exercise can both elevate inflammation for many cancers and protect the body against cancerC. exercise may change can reduce the severity of cancer or fight it off altogetherD. exercise can

41、 increase in inflammation which can contribute to elevated risks for many cancers9. In the first experiment, which one is the most important result the scientists found?A. Natural killer cells are much more in the bloodstreams of runners than in the sedentary mice.B. Levels of interleukin-6 are high

42、er in the blood of the runners than in the sedentary mice.C. Exercise such as running seemed to help the mice fight against the cancer.D. Adrenaline can reduce the severity of cancer or fight it off.10. What does the underlined word “sedentary” mean?A. runB. moveC. sitD. sleep11. In the follow-up ex

44、ion in the body, depending on where and how it goes to workD. what happens inside mice at high risk for the disease that kill the immune cells12. According to the study, we can infer the fundamental substance to fight the cancer off is _.A. adrenalineB. interleukin-6C. natural killer cellsD. genes【答

45、案】8. B    9. A    10. C    11. B    12. C【解析】【分析】本文是一篇说明文，科学家通过实验发现运动能够对抗癌症。【8题详解】细节理解题。根据第二段 “Exercise is strongly associated with lowered risks for many types of cancer. At the same time, exercise involves biological stress, which typically leads to a short-

46、term increase in inflammation(发炎)which can contribute to higher risks for many cancers.”可知，运动和癌症之间的关系一直困扰着肿瘤学家和运动生理学家是因为运动既能提升很多癌症的炎症又能保护身体免于癌症的侵袭，故B项正确。【9题详解】细节理解题。根据倒数第二段中的“those IL-6 cells in turn activated the natural killer cells in the bloodstream”可知，科学家们最重要的发现是IL-6细胞激活了血液里的自然杀伤细胞，也就是与久坐不动的老鼠相

47、比，运动的老鼠血液里含有更多的自然杀伤细胞，故A项正确。【10题详解】词义猜测题。根据画线词前的“The scientists then implanted melanoma (黑素瘤) skin cancer cells into the mice before providing half of them with running wheels in their cages while the other animals remained”可知，科学家们将黑色素瘤癌细胞植入老鼠体内，然后让其中一半的老鼠上笼子里的跑步轮，而其他老鼠则坐着不动，由此可知，画线词词义为“坐着”，倒数第四段中的“

48、allowing some mice to run and others to sit”也是提示，故C项正确。【11题详解】细节理解题。根据倒数第二段中的“More remarkably, the scientists determined that adrenaline seemed to be sending biochemical signals to some of the animals IL-6 cells, making them physiologically more alert, so that when a tumor began to develop in the affected animal, those IL-6 cells in turn activated the natural killer cells in the bloodstream”可知，肾上腺素发出生化信号的IL-6细胞，使它们在生理上更加警觉，所以当动物的体内开始出现肿瘤时，IL-6反过来激活血液中的自然杀伤细胞，也就是说科学家们在实验中发现肾上腺素、IL-6细胞和自然杀伤细胞是如何对抗肿瘤的，故B项正确。【12题详解】推理判断题。根据倒数第二段中的“those IL-6 cells in turn
