A middle-aged man with a long beard was caught by the police for bad behavior and property damage. The man, Bill Wild, checked into a hotel last night, telling the clerk he would pay cash in advance and would be staying for four nights. He then asked her where the nearest store was and she told him it was John-Johns.

Wild went to the store and bought three gallons of honey and four gallons of chocolate syrup (糖浆). The cashier asked him why he wanted these things and he replied, "I’m trying to become a sweeter person." The cashier smiled at the joke. Wild drove back to the hotel. He opened all bottles and poured them into the bathtub (浴缸). He added warm water to the mix. He tuned the radio to an opera music station, took off his clothes, jumped into the tub, and started singing loudly with the music.

Fifteen minutes later, the neighbor phoned the clerk complaining about the noise. The clerk knocked on Wild’s door, but he just kept singing. She phoned his room, but he didn’t answer. Then she called the police, who arrived quickly. They broke into the room. The floor was covered in water and the bathtub was full of chocolate and honey. "He seemed so nice and friendly. Who’d have thought he was a bathtub-singing nut?" said the clerk. The police said this was the third time that Wild had been arrested for this kind of behavior.

1.The man bought lots of honey and chocolate syrup to _______.

A. have a bath to make himself sweet

B. do some interesting tests

C. give people a surprise

D. make a sweet cake

2.What caused the clerk to call the police?

A. Wild bought honey and chocolate syrup.

B. Wild mixed the water with the things he bought.

C. Wild made too much noise and disturbed his neighbor.

D. Wild didn’t pay for the check.

3.We know from the passage that _________.

A. Wild didn’t pay for the honey and the chocolate syrup

B. the clerk didn’t know Wild had behaved like this before

C. Wild had been caught at least four times before

D. Wild walked to John-Johns to buy the honey

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

There is a well-known story about a farmer found an eagle(鹰) egg. The story reminds us of the importance of developing our full potential(潜力).

One day, a hardworking found an eagle’s egg lying on the ground of his farm. He was in a hurry he paid no attention to it and placed it together with all the chicken eggs. After several days, the egg hatched(孵化）and the little eagle into the world.

The eagle thought he was same as the other chickens, the eagle pecked(啄食）and dug for worms. He ran about and sometimes jumped around, flying a few in the air like the chickens. Over the years, the eagle grew old and tired. One day he saw a splendid bird overhead, and asked, “ is that?” “That’s the king of the -- the bald eagle,” replied a chicken. “The sky is her home. We’re chickens -- our home is the farm.”

And so the eagle lived and died a chicken, for that’s what he believed he was.

Are you an eagle that like a chicken? , many people have great talents but bring them to use. Actually, we make our talents take off by developing our character strengths. Suppose there was a young man who in the world. He asked questions about his environment, explored new neighborhoods where he lived, and soon he mentally mapped out the city he lived in. He used his curiosity to make the of his talents for spatial(空间的）intelligence.

When we use our character strengths, we will that we are eagles.
