Talk show host: Today we have good news for all our coffee drinkers around the world. A new study finds that drinking coffee can help you live longer. Researchers at the Harvard School of Public Health recently discovered that drinking between three and five cups of coffee a day may prevent certain illnesses. They found that coffee can protect against heart disease, brain diseases and suicide. Walter Willett is a nutrition researcher at Harvard and co-author of the study. Professor Willet, thank you for joining us.
Professor Willet:
    Good morning. The findings of our study extend to both caffeinated and decaffeinated coffee, or decaf, as Americans often call it.
    The health benefits come not just from the caffeine in coffee, but from the compounds in the beans. Our study was large, of about 200,000 subjects included data from three ongoing studies. Subjects in the study had to answer questions about their coffee drinking habits every four years over a 30-year period.
    We found that moderate coffee drinking was linked with a reduced risk of death from many diseases. However, we found no link between coffee drinking and cancer.
    We also considered other habits such as smoking, obesity, and how active the subjects were. We also looked at what kinds of food the subjects ate, as well as how much alcohol—and what type of alcohol—they drank.
    Our research adds to a growing body of evidence. This body of evidence finds drinking a moderate of coffee may have many health benefits, including a longer life. This is according to one of the researchers involved in the study.
    Frank Hu is senior author of the study. He is also a professor of nutrition and epidemiology. He studies how food affects illness.
    Hu adds that data from the study support that drinking a moderate amount of coffee can be part of a healthy diet. But how much and when you drink coffee is important.
    Nevertheless, our study also received doubts and criticism.
    Andrew Maynard of Arizona State University claims that the health benefits documented in this new study are "small." Maynard says the study does not prove cause and effect between drinking coffee and living longer. He says the study does point to an association, or link, between drinking coffee and living longer.
    Honestly speaking, I am personally not sure how coffee is linked to certain health benefits.
    So what I can give you as the take-home message—in other words, the important thing to learn— is that if you like coffee, do not feel guilty about drinking it in moderation. If you don’t like coffee, don’t feel you have to start drinking it to be healthy. Thank you very much.
16. What do the researchers find about coffee?
17. What do we learn about the study?
18. What do we learn about Frank Hu?
19. What criticism does the study receive?

选项 A、Coffee drinkers live longer than non-drinkers.
B、Drinking coffee can help cure certain diseases.
C、Drinking coffee daily gives people enough nutrition.
D、Coffee can help protect against certain diseases.

答案D

解析 选项都是与咖啡有关的陈述,推测问题与咖啡的功效有关。根据主持人介绍,哈佛的研究发现每天喝三五杯咖啡可以预防某些疾病,如心脏病、脑疾病和自杀,所以D项“咖啡能预防某些疾病”是正确答案。录音原文说一项新研究发现喝咖啡能让人更长寿,但这并非等同于喝咖啡的人比不喝的人长寿,A项曲解原文。研究者发现喝咖啡能预防(prevent)一些疾病,而不是治愈(cure)疾病,B项错误。C项“每天喝咖啡能给你足够的营养”未在录音中提到。
