Unit 3 A healthy life 阅读理解A(2018合肥市调研性检测)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 its harmful to health, while others have weled 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 Parkinsons 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 munity 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.”【解题导语】本文是一篇说明文。主要介绍了人们对咖啡是否有益于身体健康的几种不同观点。1What is the peoples attitude towards the effects of coffee on health according to Paragraph 1?ADisapproving.BTolerant.CDoubtful.
