Question

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(抗氧化物)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 lower 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 disability,Tomata's team 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).

(   ) 11. What have the researchers 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 disability.

D.   Green tea extracts seem to increase leg muscle strength in older women.
(   ) 12. From the passage we can infer that        .

Answer 1

8. C词义猜测题，根据than—词的用法可知，比较对象应是同类。习惯喝绿茶的上了年纪的人肯定是跟不喜欢喝绿茶的上了年纪的同龄人比较。所以，peer应表"同龄人"之意。

9. C逻辑推理题。第三段中第一个or此处表"或者"或"即"之意,因此，其后"problems with daily activities or basic needs, such as dressing or bathing" 即是对functional disability的解释。C正确。

10. B主旨大意题.，本段通过讲述喝绿茶者的健康优势和社交优势，从侧面强调了喝绿茶的好处.，A项强调了证明的方式，但文中无从体现；C项过于片面；D项文不对题。

11. D细节理解题。D项内容见第七段表述。A项与文中"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."表述相悻；B项与 "The study did not prove that green tea alone kept people agile as they grew older."表述相悖；C项与 "it's not clear how green tea might offer a buffer against disability"表述相悖

12. D逻辑推理题。从文中最后一句话可推断出： 既然维生素K可能影响阻止血液凝固的药物， "影响某些药物"就符合逻辑。維生素K与咖啡因并存于绿茶及其提取物中；维生素E既然 影响阻止血液凝固的药物，那就说明使用某些 药物时它对血液没有好处；根据常识，维生素E是促进血液正常凝固及骨貉生长的重要维生 素，小剂量的使用对人体是有益而无害的 所以，A、B、C三项均应舍弃。
