【题目】80% of teens don't get enough exercise

The World Health Organization (WHO) says that 80% of the world's teens don't get enough exercise to live healthy lives. The report, which was published in the Lancet, was based on research done with students aged 11-17 in 146 different countries. The WHO has been studying teen activity levels since 2001 and reports that not much has changed since then.

The WHO says that kids should get at least an hour of medium to hard exercise every day. This could include walking, running, biking, dancing, playing sports, or many other activities.

More and more research is showing that exercise doesn't just help the body, it can help the brain, too, improving thinking, test scores, and school grades.

One big reason for the lack (不足) of activity in today's teens is technology, such as smartphones, computers, and TVs. Many teens find it very hard for them to pull themselves away from their devices (设备), whether they are texting, playing games, or watching videos or movies. The WHO warns that young people need to do less playing in the digital (数码的) world, and more playing in the real world.

Health experts want schools and families to encourage teens to be more active. Teens should take part in sports, whether on official teams or just playing around in the playground.

Experts believe that it's very important for young people to fall into these habits now, because the positive effects (积极影响) of those habits can carry on into adult (成年的) life. Studies show that the best way to tell how active someone will be as an adult is to look at how active he was as a teen.

【解析】

本文是一篇议论文。文章从世界卫生组织的一份报告说起，报告中提到世界上百分之八十的青少年没有进行足够的锻炼。一个重要的原因是科技，如智能手机、电脑和电视。健康专家希望鼓励青少年能够多锻炼，不仅锻炼有好处，而且还会对成年生活颇有助益。

【1】

根据第一段可知这项报告历时之久，涉及国家范围之广，尤其是第一句“The World Health Organization (WHO) says that 80% of the world's' teens don't get enough exercise to live healthy lives.”可知世界上百分之八十的青少年没有进行足够的锻炼，所以这是一个全世界范围内的问题，故填80% of the world's teens don't get enough exercise to live healthy lives.

【2】

根据第二段第一句“The WHO says that kids should get at least an hour of medium to hard exercise every day.”可知世界卫生组织建议青少年每天应至少进行一小时中等到高强度的锻炼，故填Kids should get at least an hour of medium to hard exercise every day.

【3】

根据第三段“More and more research is showing that exercise doesn't just help the body, it can help the brain, too, improving thinking, test scores, and school grades.”可知越来越多的研究表明，锻炼不仅有助于身体，还可以帮助大脑，提升思维能力和成绩，故填Exercise doesn't just help the body, it can help the brain, too.

【4】

根据第四段中“Many teens find it very hard for them to pull themselves away from their devices …The WHO warns that young people need to do less playing in the digital (数码的) world, and more playing in the real world.”可知青少年觉得很难让自己远离电子设备，专家也警告年轻人应该少沉浸在数码世界中，而是应该更多地在现实世界中玩，所以科技对青少年的影响可以从上述几个方面来回答，故填Many students do more playing in the digital world and less playing in the real world./ They do less exercise./ It is hard for them to pull themselves away from their devices.

【5】

根据第四段最后一句“The WHO warns that young people need to do less playing in the digital (数码的) world, and more playing in the real world.”和第五段第一句“Health experts want schools and families to encourage teens to be more active.”可知专家也警告年轻人应该少沉浸在数码世界中，而是应该更多地在现实世界中玩，而且学校和家庭要鼓励青少年多锻炼，这些都是健康专家就解决青少年锻炼少的问题提出的建议，故填Schools and families should encourage teens to be more active in sports./ Teens need to do less playing in the digital world, and more playing in the real world./ Teens should take part in sports.

【6】

最后一段的大意主要是介绍了这样一个观点：年轻人养成的习惯的积极影响会延续到成年生活中。研究表明，要判断一个人在成年后有多活跃，最好的方法就是看他在青少年时期有多活跃。本题的答案不唯一，符合题意，言之有理即可，所以答案是开放的，故填Open-ended.
