Question

【题目】Researchers say current exercise guidelines are unrealistic and argue that doctors should sometimes advise small increases in activity instead. They warn the 150-minute weekly target is beyond the reach of some people — particularly older individuals. And striving to reach these goals could mean the benefits of lighter exercise are overlooked. But public health officials say current recommendations have proven benefits in lowering the risk of heart disease.

There is increasing evidence that inactivity is linked to heart disease, Type 2 diabetes(糖尿病) and some types of cancer. UK guidelines for adults recommend at least two-and-a-half hours of moderate activity a week, in short periods of 10 minutes or more.

But in two separate articles in the BMJ, experts argue the message needs to change, with greater emphasis on making inactive people move more. Prof Philipe de Souto Barreto at the University Hospital of Toulouse, advises people who are sedentary(久坐的) to make small incremental increases in their activity levels — rather than pushing to achieve current goals. He points to previous studies which show even short periods of walking or just 20 minutes of vigorous activity a few times a month can reduce the risk of death, compared to people who do no exercise.

In the second article, Prof Phillip Sparking of the Georgia Institute of Technology, says doctors should tailor their advice — particularly for older patients. He suggests using GP visits for people over 60 to discuss "realistic options" to increase activity — such as getting people to stand up and move during TV commercial breaks.

Prof Kevin Fenton at Public Health England, says: "Everyone needs to be active every day — short periods of 10 or more minutes of physical activity have proven health benefits, but getting 150 minutes or more of moderate activity every week is the amount we need to positively impact on a wide range of health conditions. "This includes reducing the risk of heart disease and type 2 diabetes."

C. People should increase exercise properly.

D. People should achieve their current goals.

【4】Which of the following is TRUE about current exercise guidelines?

Answer 1

【答案】

【1】D

【2】D

【3】C

【4】A

【解析】本文主要讲述了人们当前对于运动量的不同意见。

【1】细节理解题。文章第一段第一句话提出了当前的运动量是不切实际的，第二句话又进一步强调每周150分钟的运动量是人们很难达到的，故目前的运动建议量为150分钟。故选D。

【2】细节理解题。根据第二段第一句话There is increasing evidence that inactivity is linked to heart disease, Type 2 diabetes（糖尿病）and some types of cancer.可知，不活动与心脏病，糖尿病以及部分癌症有关，也就是不活动可能会导致心脏病，糖尿病以及部分癌症。故D项正确。

【3】细节理解题。根据第三段Prof Philipe de Souto Barreto at the University Hospital of Toulouse, advises people who are sedentary（久坐的） to make small incremental increases in their activity levels - rather than pushing to achieve current goals.可知，他建议应该久坐的人应该逐步小幅增加他们的运动量，而不是一下子达到目前的目标。故选C。

【4】细节理解题。根据文章的前两句可以看出，作者使用了unrealistic，beyond the reach of some people等词汇，所以是不切实际的。故选A。
