An analysis by Mount Sinai researchers of over eight years of dietary data from more than 400,000 people has found that the relationship between high consumption of fruits and vegetables and a reduced risk of cancer is not as strong as commonly thought. The study is published online April 6, 2010 in the Journal of the National Cancer Institute. It is widely believed that a diet rich in fruits and vegetables can reduce the risk of cancer. In 1990, the WHO recommended eating five servings of fruits and vegetables a day to prevent cancer and other diseases. However, although many studies have been conducted since then, none have been able to confirm an association between fruit and vegetable intake and cancer resistance.
Paolo Boffetta, MD, MPH, lead author of the study and Deputy Director of The Tisch Cancer Institute at Mount Sinai School of Medicine, and colleagues analyzed data from the EPIC study to evaluate relationships between cancer risk and intake of total fruit and vegetables combined.
The EPIC followers, which are ongoing and organized by professor Elio Riboli at Imperial College in London, included 142,605 men and 335,873 women surveyed between 1992 and 2000 from 10 Western European countries. Detailed information on their dietary habits and lifestyle differences was obtained. After 8.7 years of follow – up, more than 30,000 of the study"s participants were diagnosed with cancer.
Dr. Boffetta and colleagues found a small but significant opposite relationship between high intake of fruits and vegetables and overall cancer risk. In this population, an increase of 200 grams a day of fruits and vegetables resulted in a reduction of about 3 percent of cancer risk. Vegetable consumption by itself also afforded a modest benefit but was restricted to women. Heavy drinkers who ate many fruits and vegetables had a somewhat reduced risk, but only for cancers caused by smoking and alcohol.
"The bottom line here is that, yes, we did find a protective effect of fruit and vegetable intake against cancer, but it is a smaller connection than previously thought," said Dr. Boffetta. "Any cancer protective effect of these foods is likely to be modest, at best.
"However, eating fruits and vegetables is beneficial for health in general and the results of this study do not justify changing current recommendations aiming at increasing intake of these foods," said Dr. Boffetta.

People across America are lining up at doctor’s offices, hospitals, and even shopping streets hoping to receive a flu shot .However, many of them have returned home without one.
This year’s flu season is starting early and it’s already spreading quickly .Officials said that the flu has now spread to 50states.That’s why the flu shot isn’t easy to find.
Help will soon be on its way .A manufacturer of the will ship 100,000 doses for adults, and 150,000for children soon. Although this could be one of the worst flu outbreaks in years, experts say that the flu is not a very serious disease for most people.
“We don’t need to fear or worry that something very bad will happen,” said the director of Centers for Disease control and Prevention.” Most of us will get through this fine.”
Many public hospitals only give the vaccine to the elderly, children under two , and people with bad health problems. Chris Rikon, a mother in Maryland, was able to find a shot for her 13-month –old daughter , but not her two-year-old son. “I would have felt better if both of them bad been able to get the shots.” Rikon said.
Gerberling also reminds people to use common sense during flu season. People should cover their mouths and noses when they cough ,and wash their hands often .children who have symptoms of the flu should stay home from school, and adults who develop the symptoms shouldn’t go to work .This simple prevention could prevent the illness from spreading .
Of course, there is always chicken soup to make you feel better. Scientific studies show that chicken soup actually does help people breathe better when they are sick. Scientists say that any hot liquid will help, but for some reason, soup does it best .they say that the soup’s smell may be important, but they are not completely sure why. And if you don’t like chicken, keep in mind that the healing effect comes from the soup ,not the chicken.
57．What is mainly discussed in the passage?
A．Preventing the flu by people themselves B．The lack of the vaccine
C．the spread of flu in America D．Ways to deal with the flu

A．Help in the form of vaccine has arrived
B．Chris Rikon’s case is used to prove the shortage of the shot
C．Eating more chicken can help keep the flu away

59．Chicken soup can help people with flu in the way that ____
A．chicken smell makes you feel better B．it’s delicious and makes you eat better
C．its smell gives you comfortable breath D．the chicken provides you a better mind
60．Why most of the people can’t get the flu shot?
A．Because it is expensive B．Because the manufacturer of the vaccine closed down
C．Because the flu has spread widely ,there isn’t enough vaccine
D．because only children and the elderly are given vaccine. |

PART THREE READING COMPREHENSION (30%)
Directions: Read the following three passages．Each passage is followed by several questions or unfinished statements．For each of them there are four choices marked A, B, C, and D．Choose the one that fits best according to the information given in the passage
They say a cat has nine lives, and I think that possible since I am now living my third life and I’m not even a cat. My father died when I was 15, and we had a hard struggle to make a living. And my mother, who was seriously ill in her last years, died while still in her 60s. My sister married soon after, and I followed her example within the year.
This was when I began to enjoy my first life. I was very happy, in excellent health. I had a good job in San Jose and a beautiful home up the peninsula (半岛) in San Carlos. Life was a pleasant dream. Then the dream ended. I became afflicted (使苦恼) with a slowly progressive disease of the motor nerves, affecting first my right arm and leg, and then my other side. Thus began my second life...
In spite of my disease I still drove to and from work each day, with the aid of special equipment installed in my car. And I managed to keep my health and optimism (乐观), to a degree, because of 14 steps. Crazy? Not at all. Our home was an affair with 14 steps leading up from the garage to the kitchen door. Those steps were a standard measure of life. They were my yardstick, my challenge to continue living. I felt that if the day arrived when I was unable to lift one foot up one step and then drag the other painfully after it ---repeating the process 14 times, I would be through---I could then admit defeat and lie down and die.
Then on a dark night in August, 1971, I began my third life. It was raining when I started home that night; strong winds and slashing rain beat down on the car as I drove slowly down one of the less-traveled roads. Suddenly the steering wheel jerked (猝然一动). In the same instant I heard the bang of a blowout. It was impossible for me to change that tire! Utterly impossible!
I started the engine and thumped slowly along until I came to the dirt road, where I turned in and where I found lighted windows welcomed me to a house and pulled into the driveway and honked the horn.
The door opened and a little girl stood there. When she knew what happened to me, she went into the house and a moment later came out, followed by a man who called a cheerful greeting. I sat there comfortable and dry, and felt a bit sorry for the man and the little girl working so hard in the storm.
About an hour later, the man’s voice was heard, “This is a bad night for car trouble, but you’re all set now.” “Thanks,” I said. “How much do I owe you?” He shook his head, “Nothing. Cynthia told me you were a cripple. Glad to be of help. I know you’d do the same for me. There’s no charge, friend.” I held out a five-dollar bill, “No! I like to pay my way.” He made no effort to take it and the little girl stepped closer to the window and said quietly, “Grandpa can’t see it.”

China is working hard to deal with the contaminated(被污染的)milk products scandal（丑闻）, which has so far left four babies dead, a senior official with the World Health Organization (WHO) said on Sunday.
Dr Shigeru Omi, director of the WHO Western Pacific regional office, told a press conference that China is taking the issue "seriously".
"After admitting the problems, the Chinese government is very serious about the matter and I hope the situation will be brought under control as soon as possible," Omi said.
The WHO is assisting China in looking into the scandal but will not conduct its own investigations(调查), Omi said.
Globalization means the scandal that started in China is a problem for people around the world, he said.
"Every country can be affected, so the international community should work together to solve the problem," he said.
Since the scandal over the contaminated dairy products broke, 6,244 infants have fallen ill, 150 have been diagnosed with acute kidney failure(肾衰竭), and four have died.
Investigations have shown the babies were made sick by the presence of melamine （三聚氰胺）in milk formula（配方奶粉）. Anothony Hazzard, a food safety specialist at the WHO"s Western Pacific regional office, said the decision by some countries to recall milk products imported from China was "reasonable".
"I think many countries decided on the recall, I think under this kind of situation when the picture is not yet clear, it a very reasonable position that countries take."

Glacier National Park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.
With encouragement from the park, local landowners initiated a landuse planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resourcemanaging agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict smalllot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.
The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that congress would impose a legislative solution. Nevertheless, many local residents want to retain the existing character of the area. Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns.
73. The passage mainly discusses ______.
A. the endangered species in Glacier National Park
B. the protection of lands surrounding Glacier National Park
C. conservation laws imposed by the state of Montana
D. conservation laws imposed by Congress
74. Why are the private lands surrounding Glacier National Park so important?
A. They function as a hunting preserve.B. They are restricted to government use.
C. They are heavily populated.
D. They contain natural habitats of threatened species.
75. The relationship between park officials and neighboring landowners may best be described as ______.
A. indifferent B. intimate C. cooperative D. disappointing
76. It can be inferred from the passage that a major interest of the officials of Glacier National Park is to ______.
A. limit land development around the park B. establish a new park in Montana
C. influence national legislation D. settle border disputes with Canada |
