问题     New research has found that those who work 11-hour days or more increase their chance of a heart attack by two thirds. If you’re about to embark on your usual 12-hour day at the office, you might want to pause a while—a few hours, actually. A study has found that those who spend more than 11 hours at work increase their chance of having a heart attack by two thirds.
    The team from University College London looked at more than 7,000 civil servants working in Whitehall over a period of 11 years and established how many hours they worked on average a day. They also collected information including the condition of their heart from medical records and health checks. Over the period, a total of 192 had suffered a heart attack. Then the study was published in the journal Annals of Internal Medicine, reporting that those who worked more than 11 hours a day were 67 percent more likely to have one than those who had a "nine to five" job.
    Professor Mika Kivimki, who led the study, said: "We have shown that working long days is associated with a remarkable increase in risk of heart disease. Considering that including a measurement of working hours in a GP interview is so simple and useful, our research presents a strong case that it should become standard practice. This new information should help improve decisions regarding medication for heart disease."
    "It could also be a wake-up call for people who over-work themselves, especially if they already have other risk factors," Professor Kivimki added. Around 2.6 million Britons have heart disease, where the organ’ s blood supply is blocked by the build-up of fatty deposits in the coronary arteries(冠状动脉). It is the nation’s biggest killer, claiming 101,000 lives in this country every year. Heart attacks occur when a coronary artery becomes completely blocked; if the blood supply is not restored, the section of the heart being supplied by the artery will die.
The passage mainly discusses______.
选项 A、how does the heart attacks occur
B、the experiment on heart disease
C、more and more people are suffering from heart attack
D、long time working increases the risk of heart disease
答案D
解析 主旨题。文中，作者首先介绍了一个关于工作与心脏病的研究，包括研究的背景、方法、过程和结果。而后在文章最后一段，作者介绍现在心脏病发病的情况和心脏病发作的原理。这些研究都在证实一个事实，即：长时间的工作增加患心脏病的风险。故A、B、C的描述都不全面。只有D，“长时间工作增加心脏病发病率”最全面，是文章主要讨论的内容，故为本题答案。
