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.

【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.

【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.

【推荐1】Students in American schools learn from an early age to give presentations (演讲) as part of their regular classroom activities. Children as young as five years old often give brief talks about objects they bring in to school called ''show and tell'', and this training is a basis for later public speaking. Even so, many native Englishspeaking adults are afraid to speak or give presentations in front of a large group.
Speaking English in public meetings is necessary for many students and employees. The best way to improve is to practice public speaking in a friendly environment. Learners need to receive feedback about what they are doing well and about their mistakes. One group that gives members the chance to practice is Toastmasters. Toastmasters is an international organization that holds weekly meetings. At the meetings, members each give a speech and give others advice about their speeches and speaking style.
Charles LeBeau is a public speaking professor and consultant. He began his career in Japan in 1982. Currently, he teaches at two universities and at the Toshiba International Training Center. He has also written books on the subject.
English language learners around the world use his book Speaking of Speech. Speaking of Speech tells about a method of teaching public speaking for nonnative speakers. Mr. LeBeau says a simple approach helps English learners.
''The approach that I've taken is to simplify and break it down. First if we look at a presentation, what's going on, there are basically three messages that the presenter is giving the audience, all simultaneously (同时). There's what I call the physical message. Physical message is basically body language. It's the way that my body, as a speaker, is talking to the audience. And then there's also the visual message. The visual messages are the slides that we now make and show the audience. The third message is the story message. The story message is the content of our presentation. So another way we can think of the story messages is that it's the verbal message, and it's what we say to the audience. The story message also includes how we organize our ideas to present to the audience. '' LeBeau said.

In the first place, television is not only a convenient source of entertainment, but also a very cheap one. With a TV set in the family people don’t have to pay for expensive seats at the theatre, the cinema, or the opera .All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort in his part.
Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it ,so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begin to talk to each other again. It makes one think, doesn’t it?
There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society.

【推荐3】Science fiction novels often tum into a nightmare (噩梦) halfway through—and for blue-collar workers who are at the bottom level of the labor force, there’s a doubt about the way the robot revolution story will end. By 2035, one in three jobs could be automated (自动化) by robots, predicts PwC, a business company.
“Robotics is traditionally applied to problems that fall into the categories ‘dirty,’ ‘dull,’ and ‘dangerous,’” says Jonathan Aitken, a robotics expert at the University of Sheffield in the United Kingdom. “Automation of a repeated process is always achievable. The lack of variability means that the process is the same, time after time. This is the reason that robots fell naturally into automotive production.” It’s been the case since the first robots appeared on production lines.
But it’s not just blue-collar jobs that are feeling the difficult situation from the rise of the robots. White-collar roles are also affected, particularly those focused on data sorting, a task well-suited for artificial intelligence. Financial services is one area that has turned to automated robots carrying out trades. When a computer can pick stocks better and quicker than a human, it makes sense to make use of them, and almost all Wall Street firms do
Jobs where workers are less likely to be replaced by robots include those in health care, although surgical (外科手术的) robots, which are controlled by remote health-care professionals in order to carry out more precise procedures, are already being used in hospitals. However, the gentle touch and caring comfort of a well-trained nurse or doctor can’t be copied by a robot automation.
“It’s important to ask the question of whether we want robots doing certain jobs,” says Aitken. “In replacing a human, especially in a human-facing role, we’re being asked to accept the robot. This is something that’ll take time to achieve. People still like people.”
1. In which workplace are robots most widely used at present?A.Schools. | B.Hospitals. | C.Factories. | D.Banks. |
A.Doing repeated jobs. | B.Having no remote control. |
C.Not being automated enough. | D.Lack of human-like feeling. |
