Questions 1 to 5 are based on the following passage:

It seems like every day there's some new research about whether our favorite drinks are good for us. (76) 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 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 then on-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. (77) All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffeeis really good for you, scientists have no idea why.

1. According to the first paragraph, reporters would like to know the research findings of ____.

A. tea

B. beer

C. alcohol

D. coffee

【参考答案】D

【答案解析】由题干可以定位到第一段。根据第一段第四句It seemsjournalists are pretty interested in wine research and the same might be saidfor 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。

2. According to the passage, which of the following is TRUE?

A. Freedman and his colleagues hired 400,000Americans to collect data.

B. About four hundred thousand Americans worked for Freedman's team full time for 13 years.

C. People who took part in Freedman's research are about 50 to 70 years old.

D. People who are 50 to 70 years old seldom drink coffee

【参考答案】C

【答案解析】根据第二段第二句They analyzed data collected from morethan 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。

3. According to the author, scientists____.

A. have already proved that coffee is good for human health

B. have a long way to go before they find a way to study coffee

C. have avoided the cause-and-effect approach to study coffee

D. are still unable to figure out why coffee is good for us

【参考答案】D

【答案解析】根据第三段更后一句的And even if it turns out that coffeeis 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，从更后一段的第二句可以知道科学 家们并不是一开始就 have avoided the cause-and-effectapproach to study coffee，排除 C。

4. The word "mixed" in the first paragraph means "____".

A. both good and bad B. put together

C. both sharp and soft D. confused

【参考答案】A

【答案解析】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 coffeemight increase the risk of certain diseases and there's also been maybe morerecent evidence that coffee may protect against other diseases 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。

5. Which of the following is an appropriate title for this passage?

A. Can Beer Help You Live Longer?

B. Can Coffee Help You Live Longer?

C. Can Wine Help You Live Longer?

D. Can Tea Help You Live Longer?

【参考答案】B

【答案解析】文章虽然在第一段提到了酒(wine),但是通篇都是在谈论弗 里德曼对咖啡和人体健康的关系的研究，所以B为答案。文章没有提到啤酒(beer)和茶(tea)。
