The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as it’s harmful to health, while others have welcomed coffee for its supposed benefits to health.

According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behavior. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinson’s disease.

According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people.

According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California, San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues.

Until the scientific community reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.

When informed of these possible health benefits and harm of drinking coffee, Harwood, a high school student stated, “Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”

A．Disapproving. B．Tolerant.

C．Doubtful. D．Mixed.

D 解析：细节理解题。根据第一段可知，长期以来，饮用咖啡是否对健康有影响一直是有争议的、不确定的。一些人认为咖啡有害于健康，一些人则认为其有益于健康。D项意为“混合的，混杂的”，符合题意，故D项正确。

2．What does the underlined word “moderate” in Paragraph 4 probably mean? A．Personal. B．Slight.

C．Reasonable. D．Heavy.

C 解析：词义猜测题。根据该句中的“less than 4 cups”可知，饮用的咖啡不超过4杯；据此可以判断，该句是说，每天摄入适量的咖啡因对身体无害。据此可知，画线词意为“适度的”，故C项正确。

3．What can we infer about Harwood?

A．He’ll keep on drinking coffee.

B．He loves his high school life.

C．He often falls asleep in class.

D．He has some health problems.

A 解析：推理判断题。根据文章最后两句“Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”可知，Harwood认为，尽管喝咖啡可能会带来一些负面影响，但大多数情况下，喝咖啡对健康有好处；更不用说，他需要咖啡来保持清醒。据此可以推断，他将继续喝咖啡，故A项正确。

4．What would be the best title for the text?

A．Why People Love Coffee?

B．How Coffee Affects Health?

C．The Culture of Coffee Drinking

D．The New Findings of Heart Disease

B 解析：标题归纳题。通读全文内容可知，文章主要介绍了人们对咖啡是否有益于身体健康的不同说法。有人认为适量饮用咖啡有益身体健康，有人却认为过量饮用咖啡会增加心脏病的发病率。据此可知，B项最适合作为本文的标题。
