In 1985, 16-year-old Douglas Casa, ran the championship 10,000 meter track race at the Empire State Games. Suddenly, with just 200 meters to go, he collapsed, got back up and then collapsed again on the final straightaway, with his body temperature at dangerous levels. He had suffered an exertional heat stroke(运动型中暑). Fortunately, with immediate and proper treatment, he survived the potentially deadly stage.

Exertional heat stroke is caused by severe exercise in the heat, and is one of the top three killers of athletes and soldiers in training. When you exercise, nearly 80% of the energy you use is transformed into heat. In normal circumstances, your body can give off the heat as quickly as it’s generated through cooling methods like the evaporation(蒸发) of sweat. But with severe heat stress, your body is unable to lose enough heat due to too much exercise, which raises your corer temperature beyond normal levels. The cells no longer function properly and begin to leak their contents. If these leaky cells increase rapidly through the body, the results can be destructive.

So how do you judge an exertional heat stroke? The main criterion is a core body temperature greater than 40°C observed along with physical signs of central nervous system disorder such as very confusing behaviors or even loss of their sense of self.

As far as treatment goes, the most important thing to remember is cool first, transport second. It’s essential to start rapid cooling on site in order to lower it as quickly as possible. After any athletic or protective device has been removed from the victim, place them in an ice water container, cooling as much surface area as possible. But before you start anything. emergency services should be called.

The sun is known for giving life, but it can also take life away if we’re not careful. But although exertional heat stroke is one of the top three leading causes of death in sports, it has been 100% survivable with proper care.

1. What is the function of the first paragraph?

A.There will be minor physical and mental injury.
B.The heat in the body will be released with sweat.
C.Misfunctioning cells will damage the body seriously.

3. What is the first step to save a person suffering an exertional heal stroke?

【推荐1】It is no secret that physical activity is necessary to a person's well-being. Because children are continuously developing physically and emotionally, they are especially affected by the benefits of activity. Former First Lady Michelle Obama's Let's Move initiative reports that nearly one-third of US children are overweight or obese, and that "schools are a key setting for kids to get their 60 minutes of play with moderate activity, given the significant portion of time they spend there."

Physical education programs in schools directly benefit students' physical health. Regular exercise promotes muscles and bone development. In addition to participating in physical activity, students in P.E. learn the fundamentals of a healthful lifestyle, the building blocks upon which they can develop into healthy, knowledgeable adults.

Though the lack of attention on P.E. is often justified as an opportunity to spend more time in the classroom, studies show that physical activity contributes to improved academic performance. Regular activity during the school day is strongly associated with higher concentration levels. A statewide policy in North Carolina requires that children from kindergarten to eighth grade participate in 30 minutes of physical activity each day.

Activities in P. E. help children develop healthful social interactions. From a young age, children learn cooperation through group activities and form a positive sense of identity as part of a team. Such group activities are continually important as children grow older. The International Platform on Sport and Development states that sport has been used as a practical tool to engage young people in their communities through volunteering, resulting in higher levels of leadership and community engagement among young people.

The benefits of P.E. to a child's mental health are both complex and comprehensive. Improved physical health, academics and social interactions all contribute to good mental health. Physical activity sets the stage for a good night's sleep, provides more energy to participate in hobbies and interact with others.

1. The first paragraph implies that___________.
A.most children are growing much fatter currently
B.schools should attach great importance to physical education
C.some schools have banned physical activity
D.most parents are dissatisfied with school education
2. Physical education is ignored in a way because___________.
A.students should have more time for studyB.children dislike taking physical activity
C.schools are worried about children's safetyD.less sporting equipment is available to school children
3. Which is NOT a benefit of P.E. classes?
A.They help you study attentively.B.They provide you with a sound sleep.
C.They guarantee you a rosy future.D.They promote your social skills.

【推荐2】Tips For Staying Active Over the Holidays

The holiday season is here, which for most people, signals a departure from their typical exercise regime(方式,管理制度). Being physically active on a consistent basis can be challenging during this period especially as we travel to see relatives or host friends in our homes.     1     Exercise is also known to give you an energy boost and reduce stress levels. Considering these, you can take following tips for making physical activities regular in your lifestyle, through holidays and beyond.

    2    

This is the first rule of any sustainable exercise routine. If your workout feels like another task on your to-do list, it’ll be difficult to stick with. Therefore, be creative in identifying physical activities. Dance. Garden. Take a yoga class online. All of these count as physical activities, and even small amounts add up.

Find breaks to move throughout the day.

    3     Taking three 10-minute walks during the day —one in the morning, another during your lunch and another after dinner —produces similar benefits to spending 30 minutes at the gym. In other words, taking short movement breaks throughout your day makes for a more active lifestyle and helps meet your goals.

Make it a priority.

Most of us are managing countless responsibilities every day, so it’s vital to consider physical activities an important part of your day.    4     And, let others know when you’ll be busy exercising and how they can help you find time to do so. Having the support from others is an important element of success.

Be realistic.

Most are overly optimistic when first mapping out a workout plan. In fact, exercise isn’t necessarily at maximal intensity to be effective. Besides, you don’t have to exercise before, during and after work every day in order to hit your goals.    5    

A.Find something you enjoy.
B.Participate in various physical activities.
C.Exercise doesn’t have to take place in a gym.
D.Of course, it is realistic to avoid being injured in sports.
E.Instead, just put more movement into your current daily life.
F.However hard it seems, staying active can help not just your waistline.
G.Put it on your schedule, just as you make an appointment with a doctor.

文章大意:本文是一篇说明文。把手放在车身上,站立不动,坚持时间最长的人会得到这部车,你见过这样的“手拉松”吗? 本文对这种“手拉松”做出了详细地介绍,讲述了比赛过程,比赛过程中最难的部分以及这项比赛受欢迎的原因。

【推荐3】It is probably the strangest sport anyone has ever invented. And at first sight, it looks like the easiest. Competitors have to do two things. The first is to stand still. The second is to place their hands anywhere on the body of a car, and keep it there.


This is where things start getting difficult. Lots of people are doing the same thing. And the winner of the “handathon” contest is the person who can carry on doing it for the longest time. That person gets to own the car.

It still seems to be an easy thing to do. At the beginning it is. Anyone can stand still. But when the contest has been going for four or five days, standing still seems like the most difficult job in the world. And keeping the hand in place over this time becomes an act of serious attention. After a few days, the hand seems to belong to someone else—someone who wants to go home and get some sleep.

Competitors are allowed to take a five-minute break every hour to eat, drink or do whatever else is necessary. No one is allowed to lean on the car for support. Winners need to be able to show great powers of attention. They also need to be able to develop special skills.

Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter. Competitors in the Longview handathon certainly don’t seem to do much preparation. Most say they will prepare by “getting lots of sleep”. Others say they will “eat healthy food” or “pray for success”. The whole event gives ordinary people the chance to do something interesting and win something in the end.

Handathons are competitions, but there is little rivalry (敌对) between competitors. They help each other out and keep each other’s spirits up. People who drop out early return with food, drink and encouragement.

1. What does the word “handathon” probably mean?
A.A sport involving walking a long distance.
B.A sport involving moving hands fast.
C.A sport involving keeping hands in place for long.
D.A sport involving holding up hands steadily for long.
2. What might make handathon seem to be the strangest sport?
A.It seems to be a very easy sport but in fact very difficult.
B.At first sight people think it obviously very difficult.
C.It is very interesting and an easy to all kinds of people.
D.It requires people to have strength instead of attention.
3. Why is handathon popular?
A.Specially trained athletes can enter the competition.
B.Competitors don’t need to make any preparations.
C.Anyone who is interested can be specially trained for it.
D.Ordinary people can have the chance to play and win something.
4. Which of the following is against the rule for handathon?
A.Standing still.
B.Changing the place of hands.
C.Placing hands in one place.
D.Taking a four-minute break.
