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 (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 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).

Answer 1

8. C詞義猜測(cè)題，根據(jù)than—詞的用法可知，比較對(duì)象應(yīng)是同類(lèi)。習(xí)慣喝綠茶的上了年紀(jì)的人肯定是跟不喜歡喝綠茶的上了年紀(jì)的同齡人比較。所以，peer應(yīng)表"同齡人"之意。

9. C邏輯推理題。第三段中第一個(gè)or此處表"或者"或"即"之意,因此，其后"problems with daily activities or basic needs, such as dressing or bathing" 即是對(duì)functional disability的解釋。C正確。

10. B主旨大意題.，本段通過(guò)講述喝綠茶者的健康優(yōu)勢(shì)和社交優(yōu)勢(shì)，從側(cè)面強(qiáng)調(diào)了喝綠茶的好處.，A項(xiàng)強(qiáng)調(diào)了證明的方式，但文中無(wú)從體現(xiàn)；C項(xiàng)過(guò)于片面；D項(xiàng)文不對(duì)題。

11. D細(xì)節(jié)理解題。D項(xiàng)內(nèi)容見(jiàn)第七段表述。A項(xiàng)與文中"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項(xiàng)與 "The study did not prove that green tea alone kept people agile as they grew older."表述相悖；C項(xiàng)與 "it's not clear how green tea might offer a buffer against disability"表述相悖

12. D邏輯推理題。從文中最后一句話(huà)可推斷出： 既然維生素K可能影響阻止血液凝固的藥物， "影響某些藥物"就符合邏輯。維生素K與咖啡因并存于綠茶及其提取物中；維生素E既然 影響阻止血液凝固的藥物，那就說(shuō)明使用某些 藥物時(shí)它對(duì)血液沒(méi)有好處；根據(jù)常識(shí)，維生素E是促進(jìn)血液正常凝固及骨貉生長(zhǎng)的重要維生 素，小劑量的使用對(duì)人體是有益而無(wú)害的 所以，A、B、C三項(xiàng)均應(yīng)舍棄。
