高三英语单项填空中等难度题查看答案及解析

The relationship between exercise and cancer has long both intrigued and puzzled oncologists and exercise physiologists.

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-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 suggests 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 simultaneously 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 to 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 those 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, especially 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 released 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 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 production 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 fought 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 cells 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 killer 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.

1.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 higher 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.

2.In the follow-up experiments, the scientists found ________.

A. the hormone adrenaline has much higher levels in the blood of the exercising animals

B. how these elements in the runners — their increased adrenaline, IL-6, and natural killer immune cells fight against tumor

C. interleukin-6 can both increase and decrease inflammation in the body, depending on where and how it goes to work

D. what happens inside mice at high risk for the disease

3.According to the study, we can infer the fundamental substance to fight the cancer off is ________.

A. adrenaline                                    B. interleukin-6

C. natural killer cells                            D. genes

If you've gone through all your jigsaw puzzles and are looking for a real challenge, Kodak just released what it calls ''the world's largest puzzle'' that you can buy.

Putting your patience and jigsaw solving skills to the test will cost you both real money and a lot of space. Featuring images of symbolic landmarks shot by professional photographers, Kodak's new product will set you back between $409.99 and $599.99, and will probably take up a decent-sized room when completed.

Matching over 51,000 jigsaw puzzle pieces is sure to be a time-consuming affair, but to make it less stressful for those willing to give it a go, Kodak split the puzzle into 27 images of different international landmarks, from the Great Wall of China to the Statue of Liberty and the Taj Mahal.

They've actually made it too easy, if you ask me, packaging the pieces for each of the 27 different images in different bags, allowing you to finish them one by one before putting them together. So you're basically getting 27 smaller puzzles that you can then fix into the world's largest puzzle. Kind of tricky, if you ask me… The only real challenge will be finding somewhere to display the completed puzzle, as at 28.5 feet by 6.25 feet, it's probably going to need its own room.

Despite its subjective faults, Kodak's gigantic jigsaw puzzle is in high demand. It's already sold out on Amazon, where it was priced at $410, leaving interested parties with the option of acquiring it for at least $500 from two other retailers (零售商) listed on the official Kodak website.

1.What makes the Kodak jigsaw puzzle special?

A.It is made up of the most pieces.

B.It has the most beautiful images.

C.It is giant and takes up much space.

D.It can be bought by various means.

2.What makes it easier to complete the Kdak jigsaw puzzle?

A.Various choices of getting it.

B.Skills of professional photographers.

C.Players' patience and jigsaw solving skills.

D.Separately packaged images of world famous landmarks.

3.How much will it cost you at least to buy one jigsaw puzzle from retailers?

A.$ 409.99. B.$410.

C.$500. D.$599.99.
