问题     Every other week, new studies appear that either criticize or praise the roasted bean. Are there grounds for concern under the fragrant foam?
    Some people believe that coffee bean can lower the incidence of some diseases. First, the disease is diabetes. A study of 14,000 people in Finland which is the world’s greatest per-capita consumer of coffee found that women who drank three to four cups a day cut their risk of developing diabetes by 29 percent. For men, it was 27 percent. Researchers aren’t sure why, but suspect that the antioxidants in coffee help deliver insulin to the body’s tissues. Second, it can lower cancer. In Japan, a study of 90,000 people revealed those who drank coffee every day for ten years were half as likely to get liver cancer. Meanwhile, German scientists have identified an active compound in coffee that boosts enzymes thought to prevent colon cancer. Finally, it can also lower Parkinson’s disease. Researchers in Hawaii monitored the health of more than 8,000 Japanese-American men for 30 years and discovered that those who drank a cup of coffee a day had less than half the incidence of Parkinson’s disease. A possible clue as to why: caffeine promotes the release of dopamine, a substance involved with movement and usually consumed in Parkinson’s sufferers.
    On the contrary, there’s hot debate on whether drinking coffee is a cardiac risk. A Greek study of more than 3,000 people found coffee drinkers has higher levels of bad substances in their blood than non-drinkers. But Harvard researchers looking at the health of coffee drinkers over 20 years could not localize any extra coronary problems. Nevertheless-, a study of 2,028 Costa Ricans found those with a gene variant that processes caffeine four times slower than average, and who also drank two to three cups of coffee a day, upped their heart-attack risk by 36 percent. As this group metabolises caffeine slower, it remains in the body for longer — possibly pushing up blood pressure.
    For most of us, the humble cup of coffee is simply a harmless and enjoyable way to kick — start the day or give us an excuse for some time out. No more, no less. However, it is important to remember that different people exhibit different tolerance levels to caffeine — it is, after all, a drug.
According to the second paragraph, which of the following statements is true?
选项 A、In Finland, the study indicates women who drink coffee will be healthy.
B、In Japan, the study indicates people who drink coffee can get cancer.
C、There is an active compound in coffee that can cut the risk of getting colon cancer.
D、People who drink coffee are easy to get Parkinson’s disease.
答案C
解析 A项意为在芬兰，研究表明喝咖啡的女性身体将是健康的。根据第二段第三句“A study of…women who drank three to four cups a day cut their risk of developing diabetes by 29 percent．”可知，喝咖啡可以降低患糖尿病的几率，没有提及喝咖啡一定健康，A项不符合文意；B项意为在日本，研究表明喝咖啡的人会患癌症，根据第二段第七句“In Japan…those who drank coffee every day for ten years were half as likely to get liver cancer．”可知，B项恰与文意相反，C项意为咖啡中的抗氧化物质可以帮助胰岛素传到到身体的各部分组织中，根据第二段第八句“German scientists have identified an active compound in coffee that boosts enzymes thought to prevent colon cancer．”可知，C项符合文意，D项意为喝咖啡的人容易患帕金森病，根据第二段第十句“Researchers in Hawaii…those who drank a cup of coffee a day had less than half the incidence of Parkinson’s disease．”可知，D项与文意相反，故正确答案为C选项。
