Every student has tests when they are at school. But have you ever been so worried about the tests that you can’t fall asleep at night? Have you ever felt sick or had a headache during a test?

__1.___This worry in your mind can make your body feel bad. You may feel angry, frustrated, scared, or afraid, which can give you a stomachache or a headache.

___2.___ Good or normal stress might happen when you are called to answer a question in class or when you have to give a speech. This kind of stress can help you to get things better done. __3.__

___5.__That means making good decision about how to spend your time. If you are only dealing with school stuff and have no time to play, you can get stressed. Make sure you keep your SELF in mind: Sleep, Exercise, Leisure and Food.

C. The best way to keep stress away is to have a balanced life.

D. That kind of stress isn’t going to help you, and it can actually make you sick.

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. adrenalineB. interleukin-6

C. natural killer cellsD. genes

A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.

Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds’ heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.

The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin numbers is caused by other factors.

Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans.  “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged(延长) heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been ‘disturbed’ when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.

However, Boris Culik, who monitored the Adelie penguins, believes that Nimon’s findings do not invalidate his own research. He points out that species behave differently — and Nimon’s work was with Gentoo penguins. Nimon and her colleagues believe that Culik’s research was methodologically flawed（使无效） because the monitoring of penguins’ responses needed capturing and restraining（控制） the birds and fitting them with heart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently.

1.According to the passage, what overall message is presented?

A. No firm conclusions are drawn.

B. Neither Culik’s nor Nimon’s findings are of much value.

C. Penguin reduction is closed related to tourist behavior.

D. Tourists are not responsible for the fall in penguin numbers.

2.Which ONE argument of the following is stated in the passage?

A. Penguins are harder to research when they have young.

B. Tour operators should encourage tourists to avoid Antarctica.

C. Not all penguins behave in the same way.

D. Penguins need better protection from tourists.

3.What do you notice about the views presented in the passage?

A. They are groundless.B. They are factual.

C. They are descriptive.D. They are conflicting.

4.What does the underlined word (final line) probably mean?

A. later onB. calmly

C. separatelyD. in the same place
