Few people would question the value of taking part in sports for young people．With proper training，supervision，protective equipment and techniques，and an proper emphasis on winning，sports can develop a healthy body and spirit and a life-long interest in being active and fit .Without such measures，childhood sports can lead to injuries and even paralysis or death．

Even in the best conditions，no activity can be risk—free．But most serious hazards are preventable．Cyclists and football players can reduce their risks by wearing helmets；hockey players by wearing masks；basketball and tennis players by wearing eye guards；baseball players by wearing batting helmets．

Besides，risks to individual players can often be found，and thus prevented，through a properly performed medical exam before a child plays．For accidents that may not be preventable，having an emergency plan and first-aid equipment，and someone trained to use the equipment，can be lifesaving．

Still，each year，according to the American College of Sports Medicine，more than 775,000 children under 14 are treated in emergency rooms for sports injuries，nearly half of them preventable．An estimated 300,000 athletes experience exercise—related head illnesses each year，and almost all of them should have been avoided．

Further，from half to three—fourths of sports-related concussions（脑震荡） are never even diagnosed；the injured are often sent back in to play too soon and put at risk of another more serious brain—damaging concussion．To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www.SportsSafety.org.

A．All the accidents can be prevented．

2．What does the underlined word “hazards”(in paragraph 2)mean?

3．It is implied in the passage that        ．

A．prevention of injuries is not paid enough attention to

B．children under 14 are more easily hurt in sports

C．most head illnesses are related with exercise

D．none of the head illnesses should have happened

4．What can coaches mainly learn from the online safety course?

A．How to cure brain-damaging concussion．

C．How to predict the possibility of brain damage．

顾名思义，人肉搜索就是利用现代信息科技(电视、电脑、广播、新闻报刊等)，变传统的网络信息搜索为人找人、人问人、人碰人、人挤人、人挨人的关系型网络社区活动，变枯燥乏味的查询过程为一人提问、八方回应，一石激起千层浪，一声呼唤惊醒万颗真心，千方百计的搜索体验。人肉搜索不仅可以在最短时间内揭露某某门背后的真相，为某三某七找到大众认可的道德定位，还可以在网络无法触及的地方，探寻并发现最美丽的丛林少女，最感人的高山牧民，最神秘的荒漠洞窟，最浪漫的终极邂逅……人肉搜索追求的最高目标是：不求最好，但求最肉。而与刺青、美白、护肤、减肥等直接在人肉上施行的种种行为无关。

2008年1月9日，天涯论坛一位网友在浏览到姜某的MSN空间后，在天涯八卦义愤发帖，标题为《看到一个MM自杀前的博客因为小三……她从24楼跳下去了好惨》，帖子全文转载了姜某自杀前的博文。1月10日晚，一个自称姜某的朋友的朋友的网络友发了题为《哀莫大于心死，从24楼跳下自杀MM最后的BLOG日记，是我朋友的朋友》的帖子。2008年的第一场网络风暴由此展开。网友在漫骂谴责之后，动用了所谓的“人肉搜索”。公布了姜某丈夫王某和第三者的详细资料，在网上号召其所在行业驱逐他们，激动的网友甚至找到了王某父母的家，在其门口用油漆写下了“逼死贤妻”等字样。很多网友将此事闹到自己的单位，王某因此遭到辞退，其他单位一接到王某求职也退避三舍。王某父母的住宅被人多次骚扰，门口被贴满诬陷恐吓的标语。王某请求法院判令参与人肉搜索3家网站停止侵害自己的名誉权，消除不良影响，公开赔礼道歉，并承担自己的资损失、精神损失共计13.5万元。
