    New research suggests that cutting daily sitting time to less than three hours might extend your life by two years.
    “Humans were designed to move. But modern lifestyles and office jobs rarely encourage us to walk around,” says Peter Katzmarzyk, an expert at the University of Louisiana.
    “Sitting is common in our lives today. We sit while we’re driving, eating and watching TV. And many of us sit for many hours at work.” Katzmarzyk said.
    “We can’t throw away physical activity. It’s extremely important. We have 60 years of researchers showing us that.” Katzmarzyk said.
    Katzmarzyk and other researchers are trying to discover how sitting all day affext our lifespans(寿命).
    “This is a relatively new area of study…Studies that have assessed the relationship between sitting and death or television viewing and death have been very rare in the last four or five years,” said Katzmarzyk.
    Katzmarzyk and his colleagues analyzed data from these studies, which involved almost 167,000 adults. Then they turned to a government-run survey of Americans to find out exactly how much time people spend sitting and watching.
    Not only did the team find that U.S. citizens could live longer by sitting less, they found that cutting TV time to less than two hours a day could add an extra 1.4 years to their lives.
    People who’ve spent half their waking lives sitting down might well ask, “Is it ever too late to make a change?”
    “We would say ‘No. It’s never too late.’ Physical activity is good for you at every age.” Katzmarzyk said.
    Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. They recommend a few simple changes: frequently getting up from your desk, taking walks at lunch time, and instead of e-mailing colleagues, walking over to their offices and talking face-to-face——all activities that can be enjoyable as well as life-extending.

  • 健康环保类阅读

健康环保累阅读概念:

健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。


健康环保类文章阅读技巧:

       健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分:
       第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容;
       第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明;
       第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。
       从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。
【阅读策略】
1、概要(Summarizing):
      阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。
2、组织(Organization):
      阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。
