Elderly adults who regularly drink green tea may stay more active and independent than their peers over time，according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals that may help ward off the cell damage that can lead to disease.Researchers have been studying green tea's effect on everything from cholesterol(胆固醇)to the risk of certain cancers，with mixed results so far.
For the new Japanese study，researchers decided to examine the question of whether green tea drinkers have a lower risk of frailty and disability as they grow older.
Tomata and his colleagues followed nearly 14，000 adults aged 65 or older for three years.
They found those who drank the most green tea were the least likely to develop “functional disability”，or problems with daily activities or basic needs，such as dressing or bathing.
Specifically，almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled，compared with just over 7 percent of people who drank at least five cups fl day.
The study did not prove that green tea alone kept people active as they grew older.
Green-tea lovers generally had healthier diets，including more fish，vegetables and fruit，as well as more education.lower smoking rates，fewer heart attacks and strokes，and greater mental sharpness.
They also tended to be more socially active and have more friends and family to rely on.
Although it's not clear how green tea might offer a buffer(缓冲剂)against disability，Tomata's team did note that one recent study found green tea extracts(提炼物)seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts，they do contain caffeine and small amounts of vitamin K，which means it could block drugs that prevent blood thickened.

Sheep, like turkeys and ostriches, are not considered the cleverest animals. British scientists said last Wednesday human may have underestimated(低估) the woolly creatures. They could be much smarter than we think.
Researchers at the Babraham Institute in Cambridge, southern. England, have shown that animals have a good memory system and are extremely good at recognizing faces--which they think is a sure sign of intelligence.
Behavioral scientist Keith Kendrick and his friends trained 20 sheep to recognize and distinguish(区别) 25 pairs of sheep faces and used electrodes(电极) to measure their brain activity, which showed they could remember 50 faces for up to two years.
"If they can do that with faces, the fact is that they have to have reasonable intelligence, otherwise, what is the point of having a system for remembering anything else," Kendrick said in an interview.
So hours of seemingly mindless eating grass may not be so mindless after all.
Kendrick believes sheep got their reputation as dumb animals because they live in large groups and do not appear to have much ind
ividuality and are frightened of just about everything.
All animals, including humans, once they are frightened don't tend to show signs of intelligent action," he explained.
In research reported in the science journal Nature, Kendrick and his team showed that sheep, like humans, have a specialized system in the brain, which allows them to distinguish between many different faces that look extremely similar.
"The most important findings of the study is that they are able, both from a behavioral point of view and from looking at the way the brain is organized, to remember a large number of faces of individuals for a very long time," said Kendrick. "It is a very strange system. They are showing similar abilities in many ways to humans. "

1.
From the first paragraph we can find that ______.
1. A.
  people used to think sheep are smarter than the other animals
2. B.
  people used to raise sheep in a wrong way
3. C.
  people don't consider sheep as clever animals
4. D.
  people have done a lot of research on sheep
2.
From what Kendrick said in the interview we learn that ________.
1. A.
  scientists have learned a lot about sheep's intelligence
2. B.
  scientists have learned little about sheep's intelligence
3. C.
  scientists can't do anything more about sheep's memory
4. D.
  scientists don't have to research animals' memory

2. B.
  it is not right for people to raise sheep in groups
3. C.
  when sheep eat grass in the fields their minds may be active

Wine drinkers tend to buy healthier food than beer drinkers, according to a Danish study published on Tuesday on the website of a weekly medical magazine.
People who bought wine at the store were also more likely to buy fruit, vegetables, fish, lean meat (瘦肉) and milk than beer buyers did, said the study.
Beer buyers were more likely to buy frozen dinners, cold cuts, pork, sugary products, and soft drinks.
The study was conducted by four researchers from the National Institute of Public Health over the course of six months.
Alcohol researchers Erik Schulenburg and Marten Greenback and two other doctors collected 3.5 million receipts from 98 stores. The customers at the stores represented a large number of Danish people, they said.
“Our results confirm international studies which show that wine drinkers tend to eat more fruit, vegetables and fish and rarely eat fats, compared to those who like other kinds of alcoholic drinks,” they concluded.
Wine buyers also tended to have higher education levels, higher earnings and be in better mental health, they added.
Their interest in consumers’ shopping bags followed a series of studies in the Danish media. The studies suggested that wine drinkers ran a lower risk of cardiovascular (心血管的) disease and some types of cancer than beer drinkers.

American researchers have developed a technique that may become an important tool in fighting AIDS virus from attacking its target-cells in the body's defense system.When AIDS virus enters the blood，it searches for blood cells called T4 lymphocytes(淋巴细胞).The virus connects to the outside of T4 lymphocytes.Then it forces its way inside.There it directs the cells' genetic material to produce copies of the AIDS virus.This is how AIDS spreads.
Researchers think they may be able to stop AIDS from connecting to T4 ceils.When AIDS virus finds a T4 cell，it actually connects to a part of the cell called CD4 protein.
Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood.This way the AIDS virus will connect to cloned protein instead of the real ones.Scientists use genetic engineering methods to make the clones.Normally a CD4 protein remains on the T4 cell at all times；the AIDS virus must go to it.
In a new technique，however，the cloned CD4 protein is not connected to a cell.It floats freely，so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells.One report says the.AIDS virus connects to cloned protein just as effectively as it connects to real protein.That report was based on tests with blood cells grown in labs.The technique is just now beginning to be tested in animals.If successful，it may be tested in humans within a year.

On a cold January morning in a Washington, DC Metro Station, a man with a violin played for about an hour. During that time about 2,000 people went through the station, most of them on their way to work.
After 3 minutes a middle-aged man noticed there was a musician playing. He stopped for a few seconds and then hurried on. Four minutes later the violinist received his first dollar: a woman threw the money in the hat without stopping and continued to walk. After 6 minutes, a young man leaned against the wall to listen to him, then looked at his watch and walked away. After 10 minutes, a 3-year-old boy stopped but his mother dragged him along hurriedly. This action was repeated by several other children. Every parent, without exception, forced their children to move on quickly.
Finally only 6 people stopped and listened for a short while. About 20 gave money, but continued to walk at their normal pace. The man collected a total of $ 32. When he finished playing, no one applauded.
The violinist was Joshua Bell, one of the greatest musicians in the world. He played one of the most intricate (复杂的) pieces ever written, with a violin worth $ 3.5 million dollars. Two days before, Joshua Bell sold out a theatre in Boston where the seats averaged $ 100 each.
The program was organized by the Washington Post as part of a social experiment about understanding, taste, and people’s social position. In a common place environment, at an inappropriate hour, do we appreciate beauty? Do we stop to appreciate it? Do we recognize talent in an unexpected context?
If we do not take a moment to stop and listen to one of the best musicians in the world, playing some of the finest music ever written, how many other things are we missing?

The first reality TV show in the world was called Expedition Robinson and it was shown in Sweden in 1997. Half the population of the country watched the final event and a new kind of TV program was born. Two years later in Holland , the first series of Big Brother was filmed. Again, it was a great success and the final program was watched by 15 million people. Now more than 20 countries around the world have Big Brother or Expedition Robinson on their TV screens. The ordinary people who take part in the programs are known by millions of people in their own countries and reality TV has become big, big business.
For the TV producers, reality TV is a dream come true because many of the programs cost nothing to make. At some point, the television viewers are asked to telephone the program to vote or to apply to take part in the show. It is the cost of these telephone calls that pays for the shows. One of the most popular shows is Pop Idol. In the show a group of attractive young people are made into pop stars. TV viewers vote for their favorite person on the show. The winner makes a record and millions of copies of the record are sold. His or her pictures are published on the covers of magazines or on the front pages of newspapers, and then, they are quickly forgotten.
But not everyone is happy about reality TV. In Portugal, two TV channels got into trouble because they showed too much of the personal lives of the people in the shows. In France, reality TV is called “rubbish TV” and the TV studios of Big Brother were attacked three times in one week. In Greece, Big Brother was described as “ against human rights and civilization”

Obesity(肥胖) in children and adolescents is rising at an alarming rate. Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.
Children are considered to be overweight if the BMI(Body Mass Index) is over 85% of the weight group in their age and sex categories. If it is 95% and over, they are considered to be obese. Adolescents are generally judged according to adult criteria(标准) for obesity, although there are other considerations in this population, for many factors will affect the result of these measurements.
Causes and Risk Factors for Obesity in Children
Lifestyle Factors. Without educational or parental guidance, children are extremely greatly exposed to the cultural pressures that are largely responsible for growth of the obesity. Neither the media nor the educational system has strong programs that encourage healthy way of life, including exercise and healthy foods. The following are some specific problems created by the culture:
﹡Too much television watching plays an important role in obesity in children. Not only is it a passive activity, but television also offers countless temptations(诱惑) with its advertisements for fast foods, sugar cereals, and unhealthy snacks. In one study obesity rate were lowest in children who watched television one hour or less a day and highest in those who watched four or more hours.
﹡Sugar, particularly from soda, other sweet drinks, and fruit juice, may be major contributors to childhood obesity. One study reported that drinking soda regularly increases a child’s risk for obesity by 60%.
﹡Less physical exercise and greater sitting activities play another significant role in obesity in children. A high level of physical activity – not just using up energy – is important for weight control in young people.
Family History. Parental obesity more than doubles the risk that a young child, whether thin or overweight, will become obese as an adult. In older children and teenagers, obesity in parents starts to affect less as a predictor(预言) for body weight than their own weight. The risk may be due to environmental or genetic factors, or both.
Ethnic and Socioeconomic Factors. As in adult populations, children from lower socioeconomic groups and minority populations are at higher risk for obesity. For example, among young Mexican Americans and African Americans, there has been an increase in overweight trend of about 13% to over 23%.

1.
What’s the main idea of the passage? ______________.
1. A.
  The trend of obesity
2. B.
  Causes of obesity
3. C.
  Fight against obesity
4. D.
  Obesity in children
2.
How many main factors leading to obesity in children are mentioned?
1. A.

A villa (别墅) designed to resist earthquakes with “self-healing” cracks in its walls, thanks to nanotechnology (纳米技术) applications with self-healing polymers (聚合物), is to be built on a Greek mountainside. The villa’s walls will include special particles that turn into a liquid when squeezed (压榨) under pressure, flow into cracks, and then harden to form a solid material.
The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called “Intelligent Safe and Secure Buildings” (ISSB) is funded under the EU’s Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant（防震）homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, “What we’re trying to achieve here is very exciting. We’re looking to use polymers in much tougher situations than ever before on a larger scale.” Monitors contained in the villa’s walls will be able to collect vast amounts of data about the building over time. Wireless sensors(传感器) will record any stresses and vibrations, as well as temperature, humidity and gas levels.
The walls are to be built from new load-bearing steel frames and high-strength gypsum（石膏）board. Prof Wilkins said, “If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded（嵌入的）sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue.”

1.
The aim of the passage is to ________.
1. A.
  report a piece of interesting news
2. B.
  promote tremor-resistant homes
3. C.
  inform us of the nanotechnology development
4. D.
  tell us something about a tremor-resistant home
2.
The villa can resist earthquakes because _______.
1. A.
  it will be built on a special place
2. B.
  the cracks in its walls can be healed by the polymers
3. C.
  the special particles can make its walls stronger
4. D.
  the intelligent sensor network can tell people where there is a crack
3.
If the tremor-resistant home falls down, _______.
1. A.
  rescue work can be done more quickly and accurately
2. B.
  the intelligent sensor network will stop working
3. C.
  no one can be hurt in the earthquake
4. D.
  a warning signal will be given to other residents
4.
What Prof Wilkins said suggests that _______.
1. A.
  he is doubtful about the project
2. B.
  he thinks the tremor-resistant home is perfectly designed
3. C.
  he is confident in the tremor-resistant home
4. D.
