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．

66．Which of the following can summarize the passage best?

A．Green tea makes you less active． B．Green tea makes you less disabled． C．Green tea makes you more friendly． D．Green tea makes you more educated． 67．The underlined word“ward off”in Paragraph 2 probably means . A．form B．absorb C．remove A．prove whether the Japanese study is correct B．know if green tea drinkers are independent C．help nearly 14，000 adults aged 65 or older

D．prevent

68．Tomata and his colleagues wanted to . D．study green tea's effect on cholesterol

69．Which of the following is NOT the advantage of green tea? A．Reduce functional disability． B．Keep old people active． C．Make more friends．

D．Suffer fewer heart attacks．

B．green tea should be drunk properly D

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．
