雅思课外阅读--马拉松，跑or不跑？ 2

作为雅思考生，我们读外刊要有一定的目的性，不仅仅是为了扩大我们的阅读面，还要有意识地针对雅思考试，提高自己的水平。本文的话，我们做了一些注释，主要帮助大家习得雅思口语，雅思写作的知识。

Exercise, of course, is in general extremely beneficial for heart health. Dozens of large-scale epidemiological studies have found that people who exercise in any amount, whether five minutes a day or two hours a day or more, are much less likely to develop or diefrom heart disease than people who are sedentary.

当然，一般而言，锻炼对心脏健康大有益处。数十项大型流行病学研究都发现，无论是每天锻炼5分钟还是2个小时，锻炼身体的人患心脏病或因心脏病死亡的风险要比久坐不动的人要低得多。

But these studies, while encouraging, contain a disquieting subtext. Their plotted data typically shows some type of bell curve to the heart benefits from exercise, meaning that the morepeople work out, the less they are at risk of cardiac problems — up to a point, and then the benefits plateau or decline.

但这些研究在给予我们鼓励的同时，也包含着令人不安的潜台词。根据数据绘制出的锻炼的心脏效益曲线往往呈钟形，这意味着，在某个点之前，锻炼得越多，人出现心脏问题的风险就越低，但越过这个点之后，锻炼的效益就会出现平台期或者有所下降。

To some scientists, that finding made little intuitive sense.If a little exercise is good for the heart, why shouldn’t more be continually better?

有些科学家直觉地认为这一发现说不通。既然少量锻炼有益于心脏，那为什么加大锻炼量却不会带来更大的好处呢?

【经典句式】

make little sense说不通

intuitive直觉的

exercise运动

continually继续地

Dr. Paul Thompson, the chief of cardiology at Hartford Hospital in Connecticut and for years a dedicated marathon runner, was particularly drawn to that issue. He and his colleagues at Hartford Hospital, along with scientists at the Radboud University Medical Center in Nijmegen, the Netherlands,recently decided to delve more comprehensively than had yet been done into the available data on the topic.

作为一名有多年经验的马拉松跑者，哈特福德医院(Hartford Hospital，位于康涅狄格州)的心脏科主任保罗·汤普森(Paul Thompson)博士对这一问题特别感兴趣。最近，他和他在哈特福德医院的同事们以及荷兰内梅亨大学医学中心(Radboud University Medical Center in Nijmegen)的科学家们决定一同对这一课题的现有数据进行更深入全面地研究。
