It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now, there's been a lot of research into whether coffee's good for our health. " The results have really been mixed, " admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well. " Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400, 000 Americans ages 50 to 71 participating in the study. " We found that the coffee drinkers had a modestly lower risk of death than those no-drinkers, " he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study. When the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease, injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer. A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffees really good for you, scientists have no idea why.

单选题 According to the first paragraph, reporters would like to know the research findings of______.

【正确答案】 D

【答案解析】解析：细节题。由题干可以定位到第一段。根据第一段第四句It seems journalists are pretty interested in wine research and the same might be said for coffee．可知新闻工作者们(journalists)，即题干中的reporters，对酒(wine)和咖啡(coffee)的研究感兴趣，选项中只有coffee，因此选择D。

单选题 According to the passage, which of the following is TRUE?

【正确答案】 C

【答案解析】解析：细节题。根据第二段第二句They analyzed data collected from more than 400，000 Americans ages 50 to 71 participating in the study．可知选项C正确，故为答案。弗里德曼做研究的时候并不是雇用了这些人，所以A和B的说法都不对。在这些参与者中，明明是有的喝咖啡，有的不喝咖啡，D属于无中生有。

单选题 According to the author, scientists______.

【正确答案】 D

【答案解析】解析：细节题。根据第三段最后一句的And even if it turns out that coffee is really good for you，scientists have no idea why．可知科学家们对咖啡有益于人体的原因还没有弄明白，所以选项 D为答案。选项C干扰性较强，从最后一段的第二句可以知道科学家们并不是一开始就have avoi ded the cause-and-effect approach to study coffee，排除C。

单选题 The word "mixed" in the first paragraph means "______".

【正确答案】 A

【答案解析】解析：词汇解释题。由题干定位到第一段的内容。Neal Freedman承认说研究结果 have really been mixed，接着说道：There’s been some evidence that coffee might increase the risk of cer tain diseases and there’s also been maybe more recent evidence that coffee may protect against other dis eases as well．可知，研究证据显示了两种不同结论：咖啡会增加人患某些疾病的风险，同时咖啡又能预防另一些疾病。所以A为答案。
