雅思课外阅读--马拉松，跑or不跑？4

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。

Perhaps most surprising, older marathon runners can be just as susceptible as their sedentary counterparts to atherosclerosis, or the buildup of dangerous plaques in the arteries, the studies show. Strenuous exercise does not prevent these plaques in people who are predisposed by heredity or lifestyle to the condition.

也许最令人惊讶的是，研究表明，中老年马拉松选手与久坐不动的人一样容易患动脉粥样硬化(也就是危险斑块在动脉中堆积)。在因遗传或生活方式原因更容易患这种疾病的人当中，剧烈运动对斑块没有预防效果。

【经典句式】

marathon runner马拉松选手

be susceptible to sth易受…影响的

sedentary久坐不动的

counterpart对应的人或物

artery动脉

strenuous exercise剧烈运动

predisposed有倾向的

The act of exercising, however, may increase the risk that the plaques will rupture, precipitating a heart attack. Someone with atherosclerosis is more likely,studies show, to have a heart attack while running than while sitting quietly.

而且，运动可能会增加斑块破裂的风险，引发心肌梗死。研究显示，与静坐时相比，动脉粥样硬化患者在跑步时更可能发生心肌梗死。

【大作文万用句式】

… may increase the risk that ……可能会增加…风险

【经典句式】

rupture破裂

heart attack心脏病发

likely可能的

But many older athletes with atherosclerosis have no idea they suffer from the condition, which often causes few symptoms.

但是，很多患有动脉粥样硬化的中老年运动员对自己的病情一无所知，虽然有些症状已经出现。

【经典句式】

athlete运动员

have no idea对……一无所知

suffer from受罪;得(病)

condition病;状况

symptom症状

Similarly, according to the new review, people with certain inherited heart abnormalities, such as cardiomyopathy (an enlarged heart) or long QT syndrome,a disorder of the heart’s electrical activity, may exacerbate their conditions with strenuous exercise. The cardiac remodeling that is beneficial for most exercisers, the reviewers write, is undesirable for them and could lead to premature death, possibly contributing to the statistical downturn in health benefits from extreme exercise seen in some studies.

这项新综述还显示，某些遗传性心脏异常，如心肌病(心脏肥大)或长QT综合症(心脏电活动的紊乱)的患者在剧烈运动时，病情可能加剧。作者们在综述中写道，虽然心脏重构对大多数锻炼者有益，但对上述患者却有害，可能会导致他们过早死亡。一些研究发现剧烈运动的健康效益从统计学上偏低，可能有这方面的原因。
