Coffee is one of the world’s most widely-enjoyed beverages. Flavor aside, scientists have recognised it as a complex blend of chemical compounds with potential health effects, both good and bad. Now, new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.
    Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the link between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions.
    "There were a few studies, but the findings were not consistent across the studies," she said, "so this finding from our current study was quite a surprise. We didn’t really have any expectation of which direction it could go into." To sort out the confusion, Hashibe and her colleagues used statistical techniques to, in effect, make one big study out of the previous smaller studies.
    "We combined data across nine individual studies, so we have a lot more power than previous studies that looked at this. And we included 4,000 cancer patients who have cancer of the oral cavity and pharynx throat. And then 9,000 controls, so controls are people who do not have cancer."
    Those studies — in Europe and the United States — found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat.
    In an interview via Skype, Mia Hashibe said there was a weak link between cancer risk and drinking decaffeinated coffee, but it wasn’t statistically significant.
Questions 16 to 18 are based on the passage you have just heard.
16. What does the new research show?
17. How many cancer patients participated in Hashibe’s study?
18. What did the studies carried out in Europe and the United States find?

选项 A、There was a weak link between cancer risk and drinking decaffeinated coffee.
B、People who drink less than 4 cups of coffee a day can not keep vigorous.
C、People who drank a lot of coffee were less likely to develop cancers of the head and neck.
D、People who drank a lot of coffee were less likely to develop cancers of the mouth and throat.

答案 D

解析 选项中的link between cancer risk and drinking…coffee和drank a lot…were less likely to develop cancers表明,本题可能考查喝咖啡与人体健康之间的关系。短文中提到在欧洲和美国进行的一些研究发现,喝很多咖啡的人不太容易得口腔癌和喉癌(people who drank a lot of coffee were less likely to develop cancers of the mouth andthroat),故答案
