Such risk-taking activities as bungee jumping and rock climbing are popular with a great many people ,especially among the youths.Some people think that these activites are very dangerous and should be restricted or be forbidden and I share the same view as them. First of all,the true joy of life is based on good health.But the danger in these activities is like a sword hanging above the heads of the young who are fond of such activities and is likely to fall down at any time.If they are seriously hurt in doing these sports,they will lose most pleasure of the life and so will their parents. In addition, it is thought that the crazy activities can bring its fans fresh feelings and even thrills.The thrills ,in actual fact,are a reflection of the empty of their mind because they can do many meaningful,safe things they can do to let out their energy.Why must they choose to take part in the dangerous ones? In a word,dangerous activities should be forbidden to make sure people are safe,healthy and happy.This is also helpful to lead the youths to more practical and meaningful things.

These activities often involve speed, height, a high level of physical exertion, and highly specialized gear or spectacular stunts.The definition of an extreme sport is not exact — for example, although studies show that (road) cycling ranks as the sport with the highest rate of injury, it is not considered an extreme sport because it is not counter-cultural. The term's origin is also unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games.History The origin of the divergence of the term ＂extreme sports＂ from ＂sports＂ may date to the 1950s in the appearance of a phrase usually, but wrongly, attributed to Ernest Hemingway[10]. The phrase is＂There are only three sports: bullfighting, motor racing, and mountaineering; all the rest are merely games.＂ The implication of the phrase was that the word ＂sport＂ defined an activity in which one might be killed. The other activities being termed ＂games＂. The phrase may have been invented by either writer Barnaby Conrad or automotive author Ken Purdy.In recent decades the term extreme sport was further promoted by X Games, a multi-sport event created and developed by ESPN. The first X Games (known as 1995 Extreme Games) were held in Newport, Providence, Mount Snow, and Vermont in the United States.A history of the sports was published in 2004. Amped: How Big Air, Big Dollars and a New Generation Took Sports to the Extreme. The book provided an overview of the history, culture, and business of the sports and included interviews with athletes, company owners, and marketers.对不起啦，没有翻译
和同学去北京龙庆峡游玩的英语作文
龙庆峡游记 素闻北京延庆龙庆峡有“北方小三峡”之称， 龙庆峡位于北京市延庆县境内，翠绿的群山、幽静的峡谷、清澈的溪水、悠闲的飞鸟、壮美的高峡平湖、现代化的龙梯、叩人心弦的高空杂技、既刺激又时尚的蹦极、香火缭绕的岛上小庙，无一不吸引游人。
身临其境，恰似一幅“船在水中行、人在画中游”的优美画卷，是盛夏旅游的绝好去处，给人至纯、至美的享受，令人流连忘返。
进入景区，抬头望去，一条巨龙顺着山势攀附至山顶，粗粗的尾巴恰似要翘离地面，高大的龙头高昂在山间，好不威风，似在翘首眺望着远方的美景，伴着震耳欲聋的飞瀑跌落声似要腾空而起，一座近百米高的大坝横亘山涧，从大坝上跌落的溪水形成了壮观的飞瀑，原来那隆隆的水声是从这儿发出来的。
仰望瀑布我不由联想到李白的诗句：“飞流直下三千尺、疑是银河落九天”，飞瀑溅起的水烟弥漫在山谷间，飞溅在游人的脸上，好似天空落下的毛毛细雨，好清凉、好惬意、好舒服。
走过小桥便进入龙梯，原来攀附在山间的巨龙竟是一座现代化的电梯，弃梯蹬船，便你可以畅游了。
峡谷中水皆清冽、深不见底；夹岸高山，皆生寒树。
负势竞上，互相轩邈；争高直指，千百成峰。
回清倒影，连绵不绝。
水激石壁，哗哗作响。
好鸟相鸣，嘤嘤成韵。
横柯上蔽，在昼犹昏；疏条交映，有时见日。
每转过一道弯，呈现眼前的便是一处独具特色的美景，不管你从哪个角度欣赏，都是一副大自然创作的绝美的画卷，恰似“船在水中行、人在画中游”的极好写照。
此时，远离尘世的喧嚣，鸢飞戾天者，望峰息心；经纶世务者，窥谷忘反。
置身这幽静、纯美的峡谷中，静静品位大自然山水之美，什么烦恼、什么忧愁都会被眼前那份自然之美所取代，你的心将会被眼前仙境般的大自然之美所占据，容不得你有半点杂念，生怕一不小心会打破这份静美，不知不觉中你已被融入这份幽静、这份纯美。
游船缓缓前行，抬头望去，跨越山谷的钢索上，两位杂技演员正在表演高空骑车飞越峡谷的绝技呢！钢索距水面足足有几百米高，单凭肉眼观察，两位演员看上去仅仅是高空晃动的两个小人影，根本看不清面目，和这青山秀水组成了一幅至美的画面。
远处的悬崖峭壁间，更惊人的一幕出现眼前了，有人从崖壁探出的平台上纵身飞入峡谷，没等人们反应过来，那人被倒吊着双腿荡来荡去，似倒挂金钟般悬在那里，好刺激！原来是喜欢冒险的青年人在蹦极，真是大开眼界，还是位女孩子做出那惊人的一幕呢！一艘小船快速划至她身旁，工作人员迅速帮其解开绳索，把她送达岸边。
人们替她悬着的一颗心终于放下。
到了湖心岛，攀岩而上，山顶竟还有一座小巧的庙宇，为这青山秀水点缀了生机。
三峡大坝合拢了，高峡出了平湖，三峡的美景和我们无缘了，可置身在龙庆峡里，你仍可以领略旧时三峡的壮观场面的。
别了龙庆峡，我意兴盎然。

挑战自我作文600如蹦极
挑战不是一个名词，而是我们每个人突破自我的一个小关卡.它需要我们用勇气去奋斗，用自信去完善，用努力去拼搏.只有去追寻它才会尝到它给我们带来的趣事，我们才会造就出属于我们自己的那份勇敢.我不是一个敢于挑战自我的人，在喧嚣和安静之中，我更喜欢安静，在安静之中去体会那种独特的感觉.平常一些小活动之类的我也从没想过去触及，有时就连犯了错误都不太敢去勇于承担……就在这些平平凡凡的琐事里，又有一个小错误降临了.那是在一节英语课上，老师要我们拿出昨天布置回家写的那张试卷，说是要讲一些重点的题，但由于某种原因，她得知我们班有些人有那张试卷的答案，于是她就半开玩笑的问道：“你们是不是自己写的啊？”“是！”我们异口同声的答到.老师又有些怀疑的问道：“真的吗？”“是真的.”“那是自己写的请举起你的右手.”一秒过去了，有几个人厚着脸皮举起了手.二秒过去了，又有些同学们与内心经过一阵激烈的战斗后，也陆陆续续的举起了手.三秒过去了，我终于也“战胜”了内心的那些惭愧也举起了手.四秒过去了，老师略点了点人数，说道：“嗯，还不错，有一半以上的人是自己写的，不知道有没有人骗老师哦！好了，放下吧！”老师话毕，我也惭愧的放下了手，低下了头.默默在心里念到：唉，又撒谎了，下次一定要诚实一点，老实承认.现在想象，这倒不是撒没撒谎的问题，而是对自我的挑战的勇气大不大的问题.如果我没举起手，承认了自己抄了答案，心里是否会好受一点？如果我没举起手，我的勇气是否会增大点？如果我没举起手……可是现实是残酷的，世界上哪里会有如果这种果子？如果就像是王母娘娘的仙桃，三千年一开花，三千年一结果，三千年一成熟，成熟后就又被孙悟空给吃了个精光.所以，这个世上是没有如果的.我们要像我们老师说的那样：“过去的就让他成为历史吧！我们要放眼于未来.”挑战自我，勇于承认错误；挑战自我，敢于承担责任，挑战自我，敢于迈出第一步.我们要敢于挑战自我，挑战真实的自我！

人在离水面50m左右的位置时，做自由落体运动，处于完全失重状态，头感觉不到安全帽的作用力。
当人下落到离水面28m处时，开始匀减速下落。
自由下落的高度：s1=76-28m=48m 匀减速运动的距离：s2=28。
V^2=2gs,V^2=2as2,a=s1/s2g=48/28*10=17m/s^2.方向竖直向上。
安全帽的质量：m=G/g=5kg， 则其颈部要用135N的力才能拉住安全帽。
