公共英语三级模拟试题阅读A6：

Green tea is rich in polyphenols and has strong antioxidant activity.It shows anticancer and cardioprotective effects in vitro and animal models.We also hear from doctors about the health benefits of green tea.However,there are few clinical studies in this area,and there is no definite evidence to prove the value of this proposal.

A team of Japanese researchers was able to link green tea consumption with decreased mortality from many causes-including heart disease.The researchers tracked 40,530 healthy adults ages40 to 79 in a region of northeastern Japan where most people drink green tea,following them for up to 11 years.Those who drank five or more cups of green tea a day had significantly lower mortality rates than those who drank less than one cup a day.There were also fewer deaths from cardiovascular disease.

But no such association was seen with deaths from cancer.Nor was consumption of oolong or black tea connected with any decrease in mortality.Those teas are easier to be combined with oxy-gen in processing,which not only darkens the color of the leaves and changes their flavor but also reduces their polyphenol content.

Coffee is more complicated.It has received both gold stars and black marks in medical literature.It,too,contains antioxidants,although they are less well studied than tea polyphenols.Evidence for the health benefits of coffee is growing,however.A group of investigators from Finland,Italy and the Netherlands reports that coffee seems to protect against age-related decline in mental capacity.The scientists studied 676 healthy men born from 1900 to 1920 and followed them for 10 years,using standardized measures of brain function.Their conclusion:the men who consumed coffee had significantly less decline in mental capacity than those who didn\'t.Three cups a day seemed to provide the most protection.

Population studies like those help us form assumptions about relationships between dietary habits and long-term health.We still have to test our suppositions in controlled conditions,and measure the effects of coffee and tea on various systems of the body.
