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 (抗氧化化學(xué)物質(zhì)) that may help stop the cell damage that can lead to disease.Researchers have been studying green tea’s effect on everything from cholesterol (膽固醇) 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 researchers 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 (緩沖) 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．Fathers.

B．Brothers.

C．People of the same age.

D．People living in the same neighborhood.

2.What can be learned from the passage?

A．Antioxidant chemicals can lead to disease.

B．Those who often drink green tea can’t develop “functional disability”．

C．“Functional disability” is related to problems with daily activities or basic needs.

D．People who drink at least five cups a day are not likely to become functionally disabled.

3.What does the fifth paragraph mainly tell us?

A．How the study was proved.

B．Why green tea lovers can keep agile.

C．What healthier diets include.

D．How to lower the disability risk.

4.What has the researcher Yasutake Tomata discovered?

A．Those who drank green tea can’t develop “functional disability”．

B．Green tea alone kept people agile as they grew older.

C．How green tea might offer a buffer against disabilities.

D．Green tea extracts seem to increase leg muscle strength in older women.

5.From the passage we can infer that________.

A．vitamin K is contained in caffeine

B．vitamin K is good for our blood

C．vitamin K is bad for our health

D．vitamin K has influence on some drugs
