Elderly adults who regularly drink green tea may stay more agile ( 敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化学物质) that may help stop 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.
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 a day.
The study did not prove that green tea alone kept people agile 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. But even with those factors accounted for, green tea itself was tied to a tower disability risk, the re-
searchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it' s not clear how green tea might offer a buffer (缓冲) against disabilities, lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) 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 affect drugs that prevent blood clotting (凝固).
1.What does the underlined word "peers" mean in the first paragraph ?
A. People of the same age.
B. Brothers.
C. Fathers.
D. People living in the same neighborhood.
2.What can be learned from the passage?

American researchers say drinking tea may help strengthen the body’s defense system against infection（感染）．Doctors at Brigham and Women’s Hospital in Boston，Massachusetts，did the study．The team studied a chemical found in black，green，oolong and pekoe tea This chemical is an amino acid（氨基酸）called L-theanine．The scientists say it may increase the strength of Gamma delta T cells，which are part of the body’s defenses．
First，the researchers mixed some of these cells with antigens（抗原）found in the amino acid Antigens help the body react to infection．Then the scientists added some bacteria（细菌）．
Within twenty-four hours，the cells produced a lot of interferon，a substance that fights infection Cells not mixed with the antigens did not produce interferon．
In the second part of the study，eleven people drank five to six cups of black tea every day．Ten other people drank the same amount of instant coffee．That is dried coffee mixed with hot water．
Two weeks later，and again two weeks after that，the researchers tested the blood of all twenty-one people．They also looked at what happened when they added bacteria to the blood cells．They found that the tea drinkers produced five times more interferon after they started drinking tea The coffee drinkers did not produce interferon．
Doctor Jack Bukowski led the study He says the antigens added to the Gamma delta T cells were responsible for the increased reaction to the bacteria．He says the study also showed that the cells were able to remember the bacteria and fight them again the next time．
Earlier research already has found that tea can help prevent heart disease and cancer Doctor Bukowski says the new study must be repeated with more people．If the findings prove to be true，he says，then tea drinking might also help protect against bacterial infections．He says the amino acid L-theanine could be removed from tea and used as a drug to strengthen the body’s defenses．
73．We may know from the text that can be found in different kinds of tea．
A．Gamma delta T cells B．L-theanine
C．interferon D．bacteria
74．Tea may help strengthen the body’s defense system because it helps ．
A．the body to produce more interferon
B．the body to produce more Gamma delta T cells
C．to add some bacteria to the blood cells
D．to mix antigens with some of the cells in the body
75．According to Dr Bukowski， ．
A．the findings of the study have already proved to be true
B．he bas taken some amino acid L-theanine from tea and made a drug with it
C．further study is needed to prove the findings true
D．he is not sure whether tea can help prevent heart disease and cancer

Asia has long tradition of tea-drinking. And China is no exception.
However, lately more and more Chinese people are turning to a different . Coffee has become a/an popular choice of Chinese people living abroad and in the country's cities. In big cities such as Beijing, coffee shops seem to be on nearly every major street corner. These are not just selling drinks from Starbucks, the world-famous coffee company. Coffee businesses from South Korea and Britain are also in China.
Many young Chinese people drink coffee -- when meeting with friends. Yang Lin lives in the U.S. but comes from an area in China for growing tea. She used to drink tea while in China. But now, she says, she drinks both and for different reasons.

Ms. Yang says that as a child, her family would together in the evening and talk about the day's events over a steaming pot of tea. So now, the smell of Fujian tea brings back these family memories.
On average a person in China drinks about five cups of coffee a year. This information comes from the China Coffee Association Beijing. That is far below the world average of 240 cups a year. But the association says the amount of coffee that Chinese drink is by about 15 percent every year.

Teenagers who spend hours in front of the television may have a poorer diet as young adults.
A study，which included nearly 1，400 high school students，found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人）five years later. Why does this happen? Should the parents take any measures?
On the one hand，people who spend a lot of time in front of the TV, especially teenagers，may snack more，and that may affect their long-term diet quality.
On the other hand，TV ads for fast food，sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.
Lead researcher Dr. Daheia J. Barr-Anderson，of the University of Minnesota in Minneapolis，told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food , those who'd watched less than two hours per day had the highest intake(吸收)of fruits，vegetables, whole grains and high-calcium food. In her opinion，parents should limit and monitor TV viewing.
As far as I am concerned，children should watch no more than two hours of television per day. And parents should set a good example by eating right，being physically active and curbing their own TV time.
1. What's the best title for this passage?
A. People should keep away from TV to keep healthy.
B. Teenagers' TV time may affect their diets later.
C. Why do teenagers like TV"
D. Parents' own habits may affect children later.
2.According to the passage，heavy TV viewers tend to＿ ．
A. eat more fruits B. eat less junk food
C. take in fewer vegetables D. take in high-calcium food
3.What suggestion does the author give the parents？
A. They must watch TV with their children.
B. They should forbid the children to watch TV.
C. They should pay attention to nutrition in diets.
D. They can't do what they don't want their children to do.
