Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes (糖尿病) patients who were given a good dose of humor for a year to prove it.
Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments.
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine (肾上腺素), considered to cause stress, which is known to be deadly.After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group           C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group.
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy.
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week.
Why did the scientists carry on the new research?

A.To find out if laughter was good to health.
B.To discover the best medicine to cure diabetes.
C.Because the number of diabetic patients is the largest in the world.
D.Because diabetic patients need more laughter than other patients.

After 12 months into the study, ___________.

A.C-reactive proteins increase 66 percent in Group C
B.the level of the hormones epinephrine stays the same in both groups
C.the level of the hormones epinephrine has dropped
D.C-reactive proteins reduced 66 percent in Group L

The underlined part “HDL cholesterol” in Paragraph 3 must be _______.

A.something bad to our health B.something good to our health
C.a kind of wonderful medicine D.a kind of dangerous disease

In what way does laughter benefit people’s health?

A.Blood is made thick by laughter. B.Laughter makes blood vessels thin.
C.Laughter increases blood pressure. D.Laughter makes blood flow fast.

三、阅读理解:
It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problems and that they have no sense of humor, at least in parent-child relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are superior, at least in a small way, and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they did approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog: you can’t win but at least you can keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself.
If you plan to control your life, co-operation can be part of that plan. You can charm others, especially parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.

When most people think of tropical islands, lined with white sandy beaches and bright blue seas, it is often the Caribbean or South Pacific that comes to mind. But for Chinese tourists who want a taste of paradise on Earth there is new place to consider. Mauritius, an island lying off the southeast of Africa in the Indian Ocean, has just been added to China’s list of tourist destinations. Rich in history, natural beauty and culture, the island has been a popular destination for the world’s tourists for many years.
On December 15 a total of eight African countries were added to the list. The others are Tunisia, Tanzania, Ethiopia, Kenya, Zimbabwe, Zambia and the Seychelles.
The island has passed through the controlling hands of a number of European powers, including Dutch, French and British. In 1968, Mauritius won its independence.
At present, over half the population of Mauritius is Hindu and another fifth is Muslim (穆斯林). Both groups are descendants (后裔) from workers brought to the island from India by the British. Some Chinese were also brought over to work. There are also descendants of African slaves and Franco Mauritians, the original settlers of the island. One of the best things about the island is the food. There is a mouth watering mix of European, Chinese and Indian flavours and seafood is very popular. A typical Mauritian dinner might have Indian chicken curry, Chinese pork, British roast beef and French style vegetables. Boiled rice is served with just about everything. All that is washed down with a plentiful supply of local beer and rum (浪姆酒).
The pleasant tropical climate and scenery provide the perfect setting to enjoy everything. The sea is full of colorful life that lives around the coral reef (珊瑚礁). This makes Mauritius a wonderful place for swimming and diving. The large number of interesting fish means it is also an exciting place for those who like to go fishing.
52. Which group of the following topics is NOT discussed in the text?
A. Food and history. B. Scenery and population.

C. Mauritius has been a popular destination for Chinese tourists for many years.
D. The main food in Mauritius is local beer and rum.
54. The underlined word "This" in the last paragraph refers to "______".

55. The text is mainly written to_______.
A. attract more Chinese to travel to Mauritius.
B. introduce some information about Mauritius.
C. give some advice on how to visit Mauritius.
D. help the visitors understand more about Mauritius.

Who takes care of the elderly in the United States today? Many people wrongly believe that when people reach old age, their families place them in nursing homes. They are left there in the hands of strangers for the rest of their lives. Their grown-up children visit them only occasionally, but more often, they do not have any regular visitors. Actually this is not true. In fact, family members provide over 80 percent of the care that elderly people need.
Prof. Samuel Preston, a sociologist at the University of Pennsylvania, studied how the American family is changing. He reported that by the time the average American couple reaches 40 years of age, they have more parents than children. This statistic (统计) shows the change in life-styles and responsibilities of aging Americans. The average middle-aged couple can look forward to caring for elderly parents some time after their own children have grown up. Moreover, because people today live longer after an illness than people did years ago, family members must provide long-term care. These facts also mean that after care-givers provide for their elderly parents, who will eventually die, they will be old and may require care too. When they do, their spouses (配偶, 指夫或妻) will probably take care of them.
Because Americans are living longer than ever, more psychologists and social workers have begun to study care-giving to improve care of the elderly. They have found that all caregivers share a common characteristic: all caregivers believe that they are the best person for the job, for different reasons. One caregiver said that she had always been close to her mother. Another was the oldest child. In other words, they all felt that they could do the job better than anyone else. Social workers interviewed caregivers to find out why they took on the responsibility of caring for an elderly, dependent relative. They discovered three basic reasons. Many caregivers believed that they had the responsibility to help their relatives. Some stated that helping others made them feel more useful. Others hoped that by helping someone now, they would deserve care when they became old and dependent.
48. It can be inferred that a middle-aged couple in the US _______.
A. spend more time with their children than with their parents
B. depend on their children’s assistance in caring for the elderly
C. don’t pay more attention to their children than to their parents

49. The most common characteristic of caregivers is ______.
A. they all have professional qualifications in care-giving
B. they all believe themselves to be the best caregiver
C. they are the eldest child in the family
D. they are close to their parents
50. Which of the following is NOT a basic reason for care-giving?
A. Respect from other members of the family.
B. Prepayment for the care they will get in old age.
C. A feeling of being needed and helpful.
D. A strong sense of duty to the elderly.
51. What is the main idea of this passage?
A. Most old people in the US are living a happy life.
B. Most old people in the US live longer today after an illness than people did years ago.
C. Most elderly people in the US are taken care of by their families, who often find the experience satisfying.
D. Most elderly people in the US prefer living with their families to living nursing houses.

I spotted (发现;认出) him at the checkout counter, bagging at No.14. His arms shook violently as he placed a carton (纸板箱;纸盒) of eggs into a plastic bag. He wore a yellow plastic name tag on which he had written “Jerry” in kindergarten penmanship (书法). He looked middle-aged but his mental age must have been about 12.
Ever since I smiled at him the first time he bagged my groceries at my local supermarket, Jerry has followed me around like an adoring fan. His lack of boundaries makes me uncomfortable. I don’t know how to avoid being noticed by him. I don’t want to speak to the manager — my complaint could get him fired. So I start avoiding him.
There are other grocery stores, but I choose this one because it employs people with disabilities, from which my brothers have also suffered.
Last Wednesday after I finished choosing what I wanted, I turned around and drove my cart to Checkout No.3, hoping Jerry would not notice me and stay at No.14.
“Paper or plastic, ma’am?” Jerry’s soft voice surprised me from behind. “Paper, please.” I noticed that the checkout stand created plenty of space between Jerry and the clerk. In this situation, he knew where to stand. The clerk said to me: “$27.30, please.” I handed my own cart, signed my receipt and stepped around the counter, where Jerry was holding my last packet of biscuits. He came towards me, stopping an inch from me. He was too close. I wanted to dash out of the store and leave behind the packet. Instead, I stood with my hand frozen on the cart. His eyes looked lonely — I knew they would follow me after I left the store. I wanted to apologize for my coldness. “I’m …I’m sorry.” A tiny voice inside me said. I tapped my head with my hand as if I had forgotten something. “Forgive me. I’m from New York City. I’m not used to people being so helpful.”
He laughed. I laughed. His eyes brightened. “It’s my job, ma’am. I like it.” he said. When he offered to push my cart, I didn’t care but nodded deeply.

Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for(对…负责) the opening of that first mine.
Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).
Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.
