P1:Good morning everyone , Today, I will talk about the extreme sports.
P2:My speech is divided into four parts. Part 1 the definition of extreme sports. Part 2 the classification of extreme sports. Part 3 I will introduce some kinds of extreme sports. Part 4 why the extreme sports become more and more popular.
P3: extreme sport is a challenging entertainment formed from the interaction between nature and human, which let us developing our full body and spiritual potential at a big extent by modern technology and instruments. The spirit of extreme sports is not only “higher faster and stronger”, but also “participation entertainment and bravery”. So countries in the word call it “ the future spots”
P4: From the picture we can see the extreme sports can be divided into land sea and air three areas. In the sea area, it includes the drift, motorboat, white-water caonoeing, water skiing, surfing etc. Then land area mainly refer to the roller skating, skateboarding,BMX.
Last air area mainly refer to Bungee jumping, a parachute jump, hot air balloon.ect。
P5:Now let me introduce 4 kinds of extreme sports .there is bungee jumping,climbing,BMX,surfing.
P6:bungee jumping is an activity that involves jumping from a tall structure while connected to a large elastic cord.the tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object,such as a hot-air-balloon. The thrill comes from the free falling and the rebound.when you falling down, the cord stretches and the jumper flies upwards again.so up and down you will feel like heaven.so did someone have done this?(yes,how do you feel ? Where did you do this)(no,if you have a chance to do this ,try it).
P7: Climbing is the activity of using one’s hands,feet,or any other part of the body to ascend a steep object. It is done indoors or outdoors,on natural or manmade structures.it has many types like ice climbing (as far as i know in 1921 a British team success on the bead jose rama peak,and in 1960 a Chinese team success on the bead jose rama peak),indoors climbing competition,traditional climbing.etc
P8:BMX is short for bike motocross.BMX began in the early 1970s when children began racing their bicycles on dirt tracks in southern California.Due to the single game in the mud,then began to take BMX to the ground,and play more fancy than skateboard ,jump higher and more exciting. P9: the last one is surfing ,surfing in the waves,you need to use their own skill and balance .surfing originated in Australia. Because of the sea around Australia,so Australia person particularly fond of surfing.if you want to surfing in china, riyuewan in hainan province is the best place.
P10:The last part is the popularity of extreme sports. Why the extreme sports become more and more popular? I summed up in three aspects:first is the work press,then is the desire for new stimulus,last one is enjoying the nature. With the fast pace of life, work pressure is heavier,it makes people’s activity space smaller. So people cannot feel the originoal stimulus. People choose the extreme sport to release the pressure. But there are a few person just want to find the new stimulus .Most extreme sports are outside,so people can enjoy the nature and have a good time. that’s why extreme sports become more and more popular.
That’s all . Thank you!
Parkour is a sport activity with the purpose of moving from one place to another as efficiently and quickly as possible,using only the physical skills of the human body.It is used to overcome obstacles,which can be any obstacle in the environment on fences and stone,to pillars,walls and bars and can be practiced both in urban areas and rural areas.
Founded by David Belle in France,parkour focuses on efficient movements to develop the training of the body and mind,to be prepared to overcome obstacles in an emergency.Can also be a form of entertainment or a way to spend your free time.This sport is also called l’art du deplacement / the art of movement / art movement or even free-running.The term “parkour” is derived from the French “parcours go combattant” in translation meaning “to overcome an obstacle” .
Free running is the term used by Sebastien Foucan in Jump London documentary to refer to parkour,term which later came to describe a sport based on acrobatics,different from the original discipline Le Parkour.
Practitioners of this discipline are called tracers .The sport is practiced mainly in urban areas,involving jumps in,on,through and around obstacles such as railings,stairs,pillars,trees,buildings,etc..They consider this kind of training a way of liberation from the constraints imposed by other sports and one standard for overcoming the induced limitations .
Parkour is classified as “wow!” an extreme sports.Practicing this discipline does not require wearing special equipment,sites developed,prepared before or other obstacles.Parkour is very simple,fluid movement from one place to another,to which are added run speed,climbing,jumping,spectacular and efficient movement,imagination,improvisation and other complex techniques.If sport “parkour” performed by you does not include items listed above,then you are doing fitness.
A damper assembly including a spherical elastomer bearing member, wherein the spherical elastomer bearing member is operable for accommodating relative motion and vibration, and a flat elastomer bearing member, wherein the flat elastomer bearing member is operable for accommodating relative motion and vibration. The damper assembly also including a substantially rigid transition shim disposed between the spherical elastomer bearing member and the flat elastomer bearing member, wherein the substantially rigid transition shim is operable for coupling the spherical elastomer bearing member to the flat elastomer bearing member. The damper assembly further including a tension member attached to the substantially rigid transition shim, wherein the tension member is operable for precompressing the spherical elastomer bearing member and increasing the cocking stiffness of the damper assembly
An extreme sport (also called action sport and adventure sport) is a popular term for certain activities perceived as having a high level of inherent danger, and that are counter-cultural. 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 terms origin is also unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games.

After the winter vacation, I will rarely go out, but every day to stay at home do not move, such as school into a little fat girl. So, my father and I made two "extreme sports"!

On one occasion, I play surprisingly good, dad sent a I hit a, he also can not receive, so he kept sending me kept hit, he was angry, I return every time he can not receive on the wink, angrily shouted: "Hey! And let me send! You just let me answer once, hum, and let me send! I hit the sheet to blow it out!" Look at his expression, it is a gorilla eyes have a banana but can not eat it!

After playing table tennis, is the second sport - sit-ups. We use the timer on Mom's phone. Each of us works for a minute. See who can do the most. My record is forty-eight. Dad's is thirty-six. Mom sometimes attends, and the record is 27. Every time, dad will be done with exaggeration arching his back, patting his chest, scowling and said: "Alas! Really tired ah!" I joked: "Dad, you do so tired, careful to become a big fat oh!"

When deciding between face-to-face communication and other types, such as e-mail and telephone calls, the kind of communication one thinks is better depends on the definition of better. Face-to-face communication is usually the most effective form because there is the least chance for a misunderstanding to occur. On the other hand, letters, e-mail, and telephone calls are more efficient means of communication. In my opinion, the latter type of communication is better because efficiency is becoming increasingly important in the workplace. There are times when information must be communicated with exactness, and at such times a face-to-face conversation would be better. However, this is not always necessary or feasible. Many times we have to communicate with people who are far away. Traveling to meet them would be both prohibitively expensive and take a great deal of time. In these cases other forms of communication, especially electronic communication, are more appropriate. In addition, letters and e-mail allow us to have a record of the communication. This can be referred back to later should any dis* arise. Finally, these are types of communication that allow us to send messages when it is convenient. We do not have to match the schedule of another person.
In conclusion, letters, e-mail, and telephone calls are more efficient means of communication than a face-to-face conversation. They allow us to save both time and money. In today’s world I think these are very important factors to consider. Therefore, I believe that these forms of communication are better.
Everyone has their favorite sport, but I think you definitely sport I like what? Let me tell you! That is, cycling, commonly known as riding a bicycle.
To learn how difficult this sport that it is not difficult, that sim* was not simple, the most important thing is to master the balance, in order to master the balance I suffered, I am so anxious for the start did not grasp the essentials, and have its own legs Green throw and hand abrasions, or can not have good balance, I really wanted to give up! At that time my mother often say in my ear the word reminds me: someone else can do you can do! Is this sentence has been encouraging me, I started down-to-earth, step-by-step learning step by step, first of all, I sat on the bike, both feet on the ground to the same as in walking
Former "walk." Such a practice, such as 35 days. I try to use a foot above the foot board to ride, and the other on the floor, "go." It may do 12 weeks training. In the end, that is one of the most critical, which is one foot on the pedal, the feet together, so that forward movement bicycle. Do not think that has been done at this time, I also happened, "the end of the air," the situation, but I do not despair, because "failure is the mother of success", as long as I continue to persevere, I believe I will succeed. Drainage into waterways, I now will not only riding, and riding a "thief away," ah!
The summer, I ride every day to 23 hours, which not only allows the body fat I had a temper, but I do find a few good friends! Look! I have my little partners to sport it!

There are many different ways of communications, such as letters, emails, or telephone calls. However face-to-face communication still remains the most efficient way of communication between people.
Firstly, in face-to-face communication people can get direct response from the other party. When we talk with our friends, we can get feedback immediately from their verbal response, body language and facial expressions. Based on these responses, we can know what's the next step to take, such as how to carry on the conversation, and change the direction or finish the conversation if necessary. Sometimes, speaking words and body languages may not mean the same thing.
Although we can hear words from a telephone conversation from our friends but we do not always know if they really mean it. This is also true in criminal inspections. Police inspectors can judge whether the suspect is telling the truth through his or her body languages, therefore get new clues and solve a criminal case more quickly. Thus, face-to-face communication is more perceptible and can help us understand a speaker's true feeling better than other ways of communication.
Secondly, face-to-face communication is the most helpful way to express ourselves. In communication it is just not enough for us to say the words; we need eye contact, body language to express our feelings. Sometimes we are so happy or angry that we are out of words. At these times, there is nothing more efficient to express our happiness or anger than a big hug or turn our face to another side. When we are a tourist in a foreigncountry, language is not always enough,
and gesticulations might help us get understood more quickly. We can order in a restaurant by sim*** pointing our fingers to the menu when we do not know how to pronounce an item exactly.
Finally, face-to-face communication is indispensable in situations such as a relationship. Lovers need body contact such as a hug, a kiss and more, which cannot be done in letters or emails. Although lovers can use letters or emails to communicate, being apart for a long time is definitely not beneficial to a relationship.
In brief, face-to-face communication is a very important way for us. It is good for betterunderstanding. It is more visible, direct and more effective than any other ways.
Sports benefit me in many ways. Firstly, sports call can make me fit and strong physically. When taking part in sports, I get the chance to train almost all parts of our bodies. In addition, sports call can maintain my psychological well being, Whenever I'm in low spirit,aking part in sports can help me forget my anxieties and worries. Besides, sports can teach me some lessons about life. Through participation, I can learn that on the playground I not only struggle for my own self but also fight for my team. Sports teach me to be considerate, cooperative and optimistic.
I am fond of sports very much. I feel that I not only gain a well balanced life through going in for sports, but also get more chances to make more friends, to move closer to nature. Sports add happiness to my everyday life when I participate in them in a proper way.
My favourite sport is football, as it is very exciting. I play footetball three times a week. Most often I play it in my school. I feel very happy when I play football in school with my friends. Sometimes I play football in the playground near my school.Football is very easy to play. If you play football very well, you can form a football team to take part in the competition.

“不要啊！别的都可以，就这个不行！”我看着眼前令人发晕的跳楼机，苦苦哀求着妈妈和小姨“放过”我。
几天前，小姨请下假来带姐姐来我家，我们决定去游乐场，于是在出发前一天晚上叫上哥哥第二天一起去。
第二天很早就出发了。天气非常好，湛蓝的天空，悠悠的白云，鸟儿在枝头歌唱，清爽的晨风抚摸着我的每一寸肌肤，是我感觉不到夏日的炎热，而是秋天的凉爽。哪怕行驶在高速路上，宽阔的.马路一望无际，在与天的交界处消失在远方，仿佛马上就会飞上天空似的。
到了游乐场，映入眼帘的是许多高大的城堡和精美的装饰物。我们直奔娱乐场所，寻找玩得第一个项目。
很快，妈妈她们停住了脚步，指着面前恐怖的跳楼机说：“先上这个。”我一怔，顿时感到害怕与惊恐，哭丧着脸说：“不要啊！别的都可以，就这个不行！”
可惜，无论我再怎么哀嚎，终究还是逃不掉“恶魔”的手掌心……我看着人们坐上去开始后，突然就以飞一般的速度升向顶部，停留一小会儿后又在毫无防备时突然下降，又上升，来回几次，才结束。
我握紧双拳，咬紧牙关，坐到位置上，双手紧紧抓着把手，紧闭着眼睛。准备了，我咽了一口唾沫，手心已经全是汗。
突然，脚底一喷气，观众大喊着要上去了，我刚睁开一下眼，机器就开始以飞的速度上升，当升到顶部停下的时候，我有一种往下坠的失重感，感觉非常难受，哥哥和姐姐让我把眼睛睁开看风景，当我睁开眼时，我被震撼到了！
游乐场的风景尽收眼底，我仿佛走进了童话世界一般，巨大的海螺、蓝色的地球、梦幻的城堡、高耸的雪山……但是就在我陶醉在这童话般的景色的时候，机器突然下降，我吓了一跳“啊！”叫了一声，并再次死死地抓住把手。
终于结束了，我下来时还有那种难受的感觉，但双脚踩在地上还是踏实了很多，妈妈走过来笑着说：“好玩吧？”小姨也说：“你那视死如归的表情可有意思了。”我摇摇头，对她们的话表示无奈，但我发现好像玩了这个后我的胆量变大了，其他的也并不恐怖，我超越了我的极限！
“走吧！去玩空中飞人！”我突然跳起来，跑向下一个目标。只留其他人在原地呆愣地看着我跑向远处，久久不能回神。
当勇猛的苍鹰盘旋于天地间搏击风雨时，它已挑战了勇气的极限；当忙碌的蚂蚁在炎炎烈日下搬运着大米时，它们已经挑战了勤劳的极限......
哦，芸芸众生都在挑战着自己的极限，只是为了实现生存的价值，为美好的生活与崇高的理想而奋战，而我们人类亦是如此。
极限，对于那些懒惰的人们来说或许遥不可及，甚至只是泡影，但在于那些积极上进，有勇气与伟大志向的人来说却是其力量的源泉，这个极限的存在使他们的生命燃起了无穷斗志。他们渴望攀上人生巅峰，挑战极限，证明自己生命的价值。
勇于，善于挑战极限会使人变得更强，更加睿智机敏，人只有拥有了挑战自己的信念，才能使自己更加投入地工作学*，从而使他的业绩更上一层楼，拥抱更美好的明天。极限是石，擦出希望之火；极限是火，点燃斗志的灯；极限是灯，照亮人生之路；极限是路，引你走进成功殿堂。极限苦成了你心中的目标，只要你肯挥洒汗水，终究浇灌出成功的硕果。
半世浮名，只是虚妄，万不能把极限错当成名利丰收——这不是应该挑战和追求的，这只是贪欲与恶念交织成的魔鬼深渊，人若以其为追求，更如陷泥沼中，不可自拔，最后在里面堙没。要知道物质上的富裕远不如精神上的富裕，宋濂的“以中有足乐者，不知口体之奉不若人”便说明了这点。我们所挑战的极限其本质便是人性之恶，而不仅仅是人的成绩或是荣利，若为后者奔走相求一生，就太过浅薄无知了，所以人要挑战极限，其根本便是拚除恶念，拥有一颗心去伪存真，淡泊名利，无欲无求的善心——这才是挑战极限的实际意义，挑战的实际意义，挑战极限不仅是为了提高自己，更是为了使自己拥有一个纯净高洁的灵魂，这样才算真正的挑战，纯粹的精神洗礼！
古今多少骚人墨容，都在挑战着极限，人性之极限，陶渊明的“采菊东篱下，悠然见南山”，王士祯的“一曲高歌一樽酒，一人独钓一江秋”——他们用自己的实际启示：挑战极限重于对精神的提高，君当如竹，高风亮节，不屈坚毅。就让我们共同挑战极限吧，为自己奋斗出一个美好未来和一个高尚的人格！
攀岩是一项极好的运动。它既可以锻炼人们的臂力和身体协调能力，又可以磨炼人的意志。在你的印象中，攀岩也许是男生专属的运动吧？如果你这么想，那就大错特错了。在攀岩这个项目上，女生虽然臂力差，可是柔韧性要比男生好很多。所以，我今天准备挑战自我，做一次攀岩的运动。
来到一个个形状不一拼成的攀岩墙下，抬头往上看，我不禁打了个冷战。“我爬得上去吗？”我疑惑地问我自己。那高度差不多有十个我这么高，五彩的岩石让我看得眼花缭乱。终于，到了考验我意志的时候了。我系上了保护绳，穿上了攀岩专用鞋，开始向上爬。刚开始爬的那一段，我爬得很快，也很顺利，毕竟我那时充满了信心，还充满了劲。可是，旁边的攀岩线路上突然上来了一个人，他像猴子一样灵活极了，不一会，就超我十来米。我真的自愧不如，但是我还是想稳扎稳打。我的脚一蹬，我的手便借着脚的力量向上抓，每抓住一个岩石，我的力气也就慢慢削弱，看着上面一块块突出来的岩石还有那么多，我感觉力不从心了，手和脚也开始不听使唤了。但是我的妈妈在下面不断地给我加油鼓劲，可我动不了了。“我到底爬还是不爬？”我心里想着。就在我犹豫的.时候，我的手掌心不停冒出汗来，呆得越久，我抓到的岩石就越滑。我极力想伸手去抓上面的岩石，可是我的手根本不是我的手。虽然一只手已经抓住了岩石，另一只手伸长、伸长再伸长，还是够不着上面的岩石。这一次，我终于体会到远在天边，*在眼前的真正含义了。
我放弃了。我松开了手，人被吊在了半空中，我的脑子里杂乱极了，跟浆糊一样。“如果我现在放弃了，是多么可惜的一件事，我前面的力气，前面所有的努力，不都白费了吗？不行，我不能就这么放弃”我暗自想道。于是我鼓起勇气，朝下面的安全员喊：“我不要下去，我要继续。”妈妈听到我这么喊，不禁大声喊道：“李如一，你是最棒的，加油！”我重拾信心，重新调整自己的身体和状态，从哪里跌倒从哪里爬起来。我用全身力气瞪起脚，手借势抓住上面的岩石……终于到达了攀岩墙最高的地方。
这一次曲折的攀岩让我真正懂得了坚持！
跳绳啊，始终是我一个过不去的坎儿。
别人跳绳，想要挑战快、多。而我呢，想挑战一下“持久力”。
“老妈老妈，我的那双运动鞋去哪儿了？”一天下午，我突然心血来潮，想要挑战一下我的跳绳新纪录；一次性跳400个。只见妈妈用狐疑的眼神望着我：“*时见你吵着不跳绳，今天是啥日子呀？”我如果是*时，我一听这话，立马把我妈耸回去。但今天，我也懒得说我妈了，只顾着找球鞋了。过了一会儿，一切准备完毕，我拿着跳绳，精神饱满，眼神中闪着光芒，一种自信、胜利的光。
“各就位，预备，跳！”我仿照运动场上的运动员，开始拼命跳，不同于他们的是：只有我一个人。我尽量使身体向前倾，然后让自己跳得高一点。“呼哧、呼哧！”我喘着气，“一、二、三、四……”我觉得心跳开始加速，越跳越快，扑通扑通。但我努力着，坚持着！
“一百九十九，二百！”我大概过了五分钟，跳到二百多下了。我觉得我快要放弃了，因为脚有点抽筋，有点痛。我灵机一动：那就一只脚在前面，一只脚在后面，减轻压力。果然，我的脚就没有那么痛了，反道越跳越轻松了！“哎哟！”我突然一个踉跄，差点儿摔倒了！好在，绳子“*安”过去了，不然，这几百个就等于白费力气了。我长舒一口气，心想：吓死本宝宝了！
不知又过了多久，我跳了六百个了！这不数不知道，一数吓一跳。这中间我一下都没有中断！虽然，我的精神还在燃烧，但我的体力已经不支持了。没办法，我继续奋力地跳着，手和胳膊都酸死了，汗水都流成了河，浸到了我的眼睛里，眼睛都睁不开了！我感觉我越来越累了！终于，我停了绳子，大口大口地喘气。我掐指一算，我跳了680个了！我不禁叫了起来：“我跳了680个，我破纪录了！”我这一刻觉得自己特别了不起！创下了一个我的历史新高度，我大声欢呼，可能有点狼狈，又有点疯狂，但这是属于我的时刻。
跳绳这个过不去的坎儿，我跨过去了！而且，我变成了一位“持久力”超长选手了。
星期天，我和小伙伴们去“绿满地”游玩。这是一个拓展训练基地，在这里，我们做了许多有益的锻炼，其中最让我引以为荣的是“极限攀爬”。它让我觉得我是最棒的。
“极限攀爬”这是一个高难度的挑战，你看“攀爬台”几乎是垂直的，有四米多高，没有任何台阶，只有一条又粗又长的绳子供“攀爬”，穿越的人只能拽着绳子，一步一步地往上爬，到了台顶，下去还是个难题，得死死地拉住绳子，再一跳一跳去往下落。
面对这高难度的活动项目，许多人望而却步，也有许多人跃跃欲试，我和好友谭鸿棣摩拳擦掌，准备攀爬。我俩同时攀登，爬到一半，他便支撑不住，只好低头认输。我勇往直前，快到顶的时候，我的手被麻绳勒得又麻又痛，我心想：放弃吧，我转念一想：快到顶了，决不能放弃。于是我一鼓作气，奋力一登，上到顶了。我抓住绳子的另一端，一跳一跳地向下落。好不容易到了地上，我舒了口气,手掌却因为用劲，变得通红通红的，有一种火辣辣的感觉，疼！可是一种胜利的喜悦却在我的心底涌动:我真棒！
我还玩了别的游戏：“穿越罗网”“浮空梯”“走木桩”“上下起伏”……这些项目，我都能顺利完成，让我有一种自豪感：“我最棒！”
当格林走上百米起点，人们期待着神话中的记录再被打破；当39岁乔丹宣布复出时，人们带着担心期待着乔丹再次一飞冲天；当蜘蛛人在大风中徒手攀爬金茂大厦光滑如镜的外立面，仰头静观的人们心跳加速；当蹦极的人们从空中跃下再弹起，一阵晕眩无限刺激油然而生。体育运动不断冲刺极限，“更高、更快、更强”体现了人类挑战极限，不断突破的精神。
当我们目睹拳王阿里颤抖的双手，当我们心碎于桑兰那牵动亿万人心的一跳，当全世界车速惊心于塞纳辉煌短暂的一生，当我们忧心于罗纳尔多那脆弱的膝盖，静心反思，挑战极限，难道意味着必须失去健康、生命？也许正像弹簧，拉力超过了弹簧的承受极限，弹簧也许就要断裂。
很多时候，我们需要不断突破极限，而在另外很多的场合，我们也许又要学会适可而止，保持生命的弹性。
要求：以“极限”为话题，写一篇800字以上的文章。文体不限，题目自拟。
挑战极限
――献给2006年挑战高考的学子
“超越梦想一起飞，你我需要真心面对……”每当耳畔响起这首歌，心中总会掀起无限的遐想，人类就是怀者这样的梦想在阔步向前的。挑战极限，其实就是把人类最大潜能尽情展现，勇于挑战极限就是把心中的梦想在现实中浓墨重彩的描绘，挑战极限，我们的人生价值将会一览无余地体现。
在人类发展的漫漫旅途中，梦想始终在召唤着我们，哥伦布、麦哲伦扬起了驶向大洋的风帆，开辟了历史的新航线；火车由隆隆前行进而变得风驰电掣；神五神六上了天，多年的飞天之梦一朝实现；无线通讯让天各一方的两颗心变得不再遥远；人类登上了月球，不停的脚步继续向宇宙攀缘……一切的一切，都像梦幻般实现。挑战极限，人类进步的车轮滚滚向前。
“文王拘而演《周易》，仲尼厄而作《春秋》，屈原放逐，乃赋《离骚》，左丘失明，厥有《国语》……司马迁，惨受宫刑，发愤著书，《史记》得以问世；曹雪琴，耐住饥寒，一部《红楼梦》“字字看来皆是血，十年辛苦不寻常”；徐悲鸿，面对洋学生的挑衅、侮辱，用第一的成绩证明：*人不是好惹的；史铁生，两腿残缺，痛心回眸，为回报母爱，憧憬生活，毅然拿起笔，写下不屈的人生；海伦·凯勒，双目失明，用双手、用一颗心成就了自己写作的人生，她的精神激励了全世界千千万万残疾人，成为人类一笔宝贵的财富。挑战极限，贝多芬、保尔·柯察金、张海迪、舟舟……一系列敢于扼住命运咽喉的人在我们头脑中一一闪现。这些在逆境中受尽磨练的人们，真正读懂了人世间的*、假丑恶，更懂得什么是真正的生活，逆境中的经历，更有助于他们创造出许多顺境中不能创造的成就。
人类永无满足，挑战的脚步遍及各个领域：吉尼斯世界记录一项项被刷新，南极大陆插上了各国科考队的旗帜，英吉利海峡多次被徒手游过，柯受良驾车飞跃了黄河……挑战，成功与失败并存，刺激与危险同在，那为何人们又对它如此钟爱？
挑战极限，正是人们热爱生命，珍惜生命的体现。人活一世，草木一秋，与其庸碌无为地活着，不如壮壮烈烈将生命绽放。流星划过天际，转瞬即逝，却将美丽铭刻人间；夕阳虽短，然而那红彤彤的灿烂却是一天中最耀眼的光华。挑战极限，证实了自身的价值与实力，展现了生命的活力。作为一个莘莘学子的我们，面对知识的挑战，面对着科技的日新月异，唯有踏实迈步，点滴积累，静心读书，勤思好问，把高考当做当前的极限，把上大学当做人生的又一起点，不断攀升，不断超越，我们的人生才会格外夺目耀眼！
人生无极限，挑战无极限，“越飞越高越精彩”将是我们不变的誓言！
好想挑战极限“滑索”
2月15日我同家人来到了三亚“呀诺达热带雨林公园 ” 玩，里面的人多得就像天上的星星一样数也数不清。
在这里面有一个玩耍项目是“滑索”。看着宣传图片上有小孩也能玩这个，我可兴奋了，很想挑战极限“滑索”。因为在热带天堂景点也有这个滑索，就是因为我的体重不达标，没能玩成。高高兴兴地朝着图标指标的方向走去，终于到了。却被公园管理叔叔拦着，对我解释说：“今天线路检修，暂停滑索”，听到这个我一愣，咱的运气怎么这样差呀！早不晚不偏偏这个时候开始检修。我失望的继续向前行进，就在下山途中，像鸟叫的声音从头顶飞过，我抬头一看，怎么滑索又开始了，上面的人欢呼着。真是让人揪心呀！眼看着时间快6点了，我很不情愿的放弃这个念头，跟随着家人一同下山。
一路上我暗自下定决心，以后绝不挑食，多吃饭，加强锻炼，下次有机会再去挑战滑索。
我们班有个“高效率”电脑手，姓张名鼎的，他一天可以玩长达6小时左右的电脑，而且他爸爸、妈妈允许他这样的，他的实力也非常的号，我一天只玩1小时电脑，但还是戴上了眼镜，我常常诅咒他，让他也戴上眼镜，我倒要看看，你视力差后，会怎么样，这个诅咒成功了。
星期五早晨来到学校，又看见张鼎在那儿嬉皮笑脸，看着我就来气，可是到了上课，我的心情立刻多云转晴，我看见张鼎从书包里掏出了一个盒子，他慢慢打开，哇，是眼睛唉，我太高兴了，快戴上快戴上！我都快疯了，快点戴上啊，哎，哎，哎！终于戴上了，他啊，戴上眼镜可好笑了，一张肥肥的脸上架这副眼镜，像个绅士，其实还是傻傻的，一点没变！
下课了，我立刻跑了过去，看着他笑了笑：“‘高效率’电脑手啊，怎么啊，哟！戴上眼镜啦，你学*真刻苦，几度的啊！哈哈哈哈.......”张鼎反笑：“哦呵呵，我左眼25呀，25呀！有眼75啊，75啊！”什么，怎么这么低，是在是牛！眼镜比我们大多数人多好，戴副眼镜，戴什么戴，装斯文，害我白高兴一场；他那眼镜，我看就是个玩具，视力又不差，还有这副眼镜，支架式跟软软的东西，摔不坏，打不烂，这不玩具是什么！
张鼎戴了眼镜，也不知道要保护一下自己的眼镜，和往常一样，玩电脑，最*也不加强保养，我看他的视力快不行喽！
请大家注意了，请保护好自己的眼睛，我们的张鼎视力那么好，没想到也会下降啊！
——以极限为话题作文800字 (菁华5篇)
有句话说得好：适度的运动有益健康。不运动或过度运动都不好。因为我喜爱运动，所以运动给我带来了无限的乐趣，我会在运动中寻找健康，寻找快乐。
最*我们学校举行了“体育达标运动会”同学们一听到这个消息，就像那脱缰的野马，生龙活虎地跳跃着，蹦跳着。我想有些同学肯定想在这次的“体育达标”中大显身手，但还有一些同学肯定在为这次的“体育达标运动会”而担忧，害怕。
“体育达标运动会”正式开始了，体育项目有：仰卧起坐，立定跳远，抛实心球，400米的跑步。同学们刚下楼，就都像一只可怕地猛虎，都在捕捉自己最理想的“食物”。首先我去参加我最拿手的项目——仰卧起坐，当哨声响起的那一刹那，我就在为我自己的目标而奋斗，我听到我的呼吸，越来越紧凑，我就在我的心里默默的喊着“加油”。当我听到我的成绩是优秀的那时候，我的心就像那盛开的鲜花，那样的美，那样的开心。从这次的“仰卧起坐”我一下子就有了信心，我相信我自己一定可以。“立定跳远”的时候，我的心一直在“扑通，扑通”的叫，我告诉自己，不要紧张，你一定可以的。虽然我战胜了前面的“猎物”，但这只“猎物”，我是享受不到它的美味啦，我一定要好好练*跳远，总有一天会让这只“猎物”被我给征服。终于到了我的弱项啦，我的弱项就是400米的跑步，在还没跑步之前，我都可以感觉到我的双腿好像要“*”一样，我安慰自己：不就是跑步嘛，有什么可怕的，前几项你都不怕，还怕这一项吗？我相信你一定可以战胜紧张这个“恶魔”的。到我跑步了，哨声一响，我就像一只被别人追杀的兔子，拼命往前跑，到跑最后一个来回时，我就又像一只虚脱的“兔子”啦。项目全部完成啦，大概一看，这次的总成绩还不错嘛，这次的功劳都应按归功于我的自信，和*时的锻炼，他们俩可都是我的功臣呀
通过这次的“体育达标运动会”，我认识到了运动是我们身边必不可少的的一样东西，它和我们吃饭，睡觉是一样的重要，如果我们不运动，时间长了就会肌肉萎缩，容易长胖的。如果要想有好身材，必须要运动，运动可是治病的良药，如果不运动，就会百病缠身，所以我爱运动，运动会使我的生活变得有趣，会让我在健康中找到快乐！
在我们班，有一个出色的组合，极限三傻。
大傻
其实，这位大傻是我们班的歌仙，网上火歌他都会唱，但是经常改变那些歌词，改的恰到好处，让人回味无穷，损人的多些。他为什么傻呢？是因为经常做傻事，经常出丑，所以才被称为大傻，上课时老师站在讲台上讲课，他坐在位置上小声的唱歌，那旁若无人的劲头，真够傻，你们想没？当他上课正唱的沉醉时少不了老师的一顿“美言”！不过他学*还好，是班里的前几名，你们可不要小看他哟！
二傻
这位二傻嘛，就是本人，你们会问我为什么傻呢？其实我可以说是我们班的歌神。我嘛，网上的歌一般都会唱，跑调、忘词也是必然的，不过我还是以原唱为主。现在回答你们的问题。我为什么傻？
我是因为成绩似过山车，分数高少低多，因为玩儿没时间，我要么说谎没作业，要么草书上阵，几乎谁都看不懂。经过我的一段傻，傻为我从正查前几名一不留神来到了倒查几名。我现在才感觉到我是真傻呀！
第二是因为我做事慢，指的是不想做的事，比如学*这件事，一提到学*我像个老年人，记不住，写不好，健忘呀。
第三我反应迟钝，比如有人拧我一下，我过几秒才会感觉到，然后愣一下才回头对他说；“你拧**嘛？”这也许是件好事吧！写到这儿我的脸都红了。后边还有我的好多傻事那！还是省略不写啦！
三傻
三傻是我们班的歌王，你们会问：“你们怎么一个这个一个那个呀？”其实我们原来的组合名是“天外歌仙”。
三傻其实也不傻，她的歌唱的比我好多了，学*吗我俩有一拼，都是坐滑梯下来的。她的反应比我快多了。有一次我俩一块儿走，迎面一道光过来，她躲开了一个不明方向的水球，落在我身上，给我降了降温。她为谦虚总是说自己傻！可能是因为古人那句“傻人有傻福”的话吧！
我们三个人从一年级就开始一起玩，一直到四年级，我希望五年级我们三个人还可以在一起。我和三傻决定到五年级，我俩的成绩一定得赶上大傻！大傻说了我们，要像有句话说的那样，“有福同享，有难同当”。我们一起并肩傻下去！
一条路，走了很久，没有尽头；一首诗，作了很久，终难完美；一杯水，一块石，折射出无限可能、无限人生：看似放了石头的杯子已经满了，然而沙子和水还可以放进去……这正如我们的人生，看似已经濒于“极限”的事物总会有“惊世”转机和意外收获！曾记否，那年小小的你，执拗地甩开父亲的手，爬上自己的“铁马”。你锁眉，你严肃，你满眼执著。终于，你登上“宝座”，用力一蹬，自行车动了。可是你的脚还够不到大大的车蹬啊。下一秒，事情可想而知……
父亲急忙挪开压在你身上的车，从摔倒到被扶起一语不发的你笑了，笑着说：“爸爸，我做到了。”也许你摔倒了，但从你执意自己骑车的那一刻起，就注定了你是成功的。因为那一刻，你挑战了自己，超越了自己年龄和身体的极限……曾记否，那年你站在小小的舞台上，那样稚拙。涨红的小脸，不自然地向上扬起的嘴角，细密的汗珠，借助你不知所安的眼睛和体侧紧握的双手，一眼就看到你脸上写着：无助。然而，那第一句的清晰歌唱，收尾时的灿烂微笑，表明了你无可争议的胜利爆发，你必将化茧成蝶，炫彩飞舞。因为那一刻，你战胜了自己，解开沉重枷锁，超越了心理极限……曾记否，汶川地震158个小时后带给你的惊喜和感动，救援的黄金时间已经过去了八十几个小时，他依然生还，虚弱但不懦弱。在黑暗中，摸索、等待是他生存的重心。然而最苦闷、最绝望的时期，他熬过来了。当第一缕阳光照进那微小的缝隙时，就已宣告了他在这场与死神的拉锯战中胜利了。
那一刻，他安全了，胜利了。生命的光辉在他身后光彩夺目，因为那一刻，他也克服了自己的生理和心理的种种困难，走出阴霾，超越了生命的极限……曾经，珠穆朗玛峰是不可征服的；曾经，南极极点是不可穿越的；曾经，马里亚纳海沟是下不去的……而今，珠峰上插遍了各国**；极点上留下了我们的足迹；海沟里还有我们的残温……这一个个的不可能现在已经变得*常无奇，不经意间我们发现：都是因为“极限”，我们超越了极限，让不可能成为可能。……蝶的飞舞是因为它超越了茧层的极限；花的芬芳，是因为它超越了苞叶的极限；果的诱人，是因为它突破了青涩的极限……漫漫人生路，我们知道，害怕退却，没有出路；我们也知道，中途抛锚，又要耽误时间；我们更知道，任其飘摇，就有触礁沉没的危险。所以，“超越”是我们的必经之路，唯有越过“极限”的高山，我们才能看到旷世奇景！
经过三天的奔波，我们一家三口终于到了目的地——黑龙江省雪乡的二郎河。
那里原本山清水秀，可因为大雪毫无征兆地从天上散落下来，大河小河都结上了厚厚的冰，山间的土地上也披上了厚厚的保暖外套。树的枝叶上也零零散散地落了一些白雪！
雪乡又名双峰林场，在张广才岭与老爷岭交汇之处，占地大约有五百公顷。雪乡距离哈尔滨市区*三百公里，距离牡丹江接*一百七十公里。这里交通方便，可直接驾车来到这片林场。因为雪乡下雪频率太过频繁，积雪期从每年的十月到次年的五月，达七个月之长。*均积雪厚度达两米，“雪乡”之名因此而来。
雪乡二郎河有一个滑圈场地。在这里滑圈，一次次地在林海雪原之间穿行，感受刺激的飞跃，心情豁然开朗，此时已经忘记了此刻的严寒，置身于雪的世界里。
我们来到了一个巨大的滑圈场，我一看四通八达的滑道，就心惊胆战，倒退了几步。这是人该来的地方吗？如果滑圈翻了怎么办？我越想越害怕！这时爸爸拉住了我的手，“快一点！”说着便跑到了雪道的最上方。我的脚下有着看不到底的65度滑道，面前只有一个这么小的滑圈，我的腿颤颤巍巍地抖动着。爸爸笑着对妈妈说：“这次儿子看来真的吓破胆了！”“才不是的呢！”我努力地反驳，但是心里还是有着害怕。我坐进了滑圈里，腿盘起来，脖子往后仰，两只手抓住安全圈。就这样，爸爸把我推了下去。我尖叫着并且闭着眼，过了一会儿，就到了终点。“还挺爽的，再来一次！”
我顺着雪道爬了上去，叫着要再来一次，妈妈说：“不行不行，该你爸了！”听了这句话，爸爸的脸突然僵住了。“我不行，不行！”我也跟着起哄：“你刚才还说我吓破胆了，你呢？”经过我们的一再要求，爸爸也坐上了滑圈，我一踢，他一下子就滑了下去，因为他太重了，一百二十多斤的身体带动这个滑圈左摇右晃，最后就滑进了雪堆里。我们哈哈大笑起来。
突然，我发现了一个更大更长的雪道，便拿着滑圈跑到了那儿。我坐到了滑圈上面，两脚一蹬，一下滑了下去。滑道中间有一个树枝，我没看见，顺着树枝一头栽进了大雪堆里。出来的时候，我好似一个面人，满身都是雪。爸爸看见了，对我说：“你还说我，你自己都进雪堆了！”伴随着笑声，我们回到了旅店！
这次的滑雪又惊险又刺激，又欣喜又害怕！
大年初一，西昌海滨公园，海滨绿道。放眼望去，除了零零杂杂的自行车外，还有一列整齐的队伍——看对了，那就是我们的车队。
由于海滨公园极大，我们只好在老海亭租了自行车，向公园里的美景骑去。
一路上，风景很美。邛海在阳光下是波光粼粼的，海边的大石头在清风下却是冰冰凉凉的。海边、路边还有着许许多多的格桑花与不知名的小野花。一棵棵高大的白桦树像士兵一般挺立在小路两旁，好不整齐的。草坪上的石板路，邛海上的白鹭、野鸭、渔船，又给美丽的海滨公园添加了几分色彩。
风景优美，但路途漫漫。晃眼过去的风景，却抵不过疲劳乏倦的身体。环海不过5公里，我的腿脚就开始酸软了，手臂也开始无力，臀部像千万颗钉子在扎似的。再加上天气炎热，我的脑袋像有几只苍蝇在里边飞似的，晕头转向的。再一看路标，再一问人，我的心开始犹豫不决了：要向前走还是原路返回？可我是明白的，往前走要走两个多小时，而返回呢，只需一小时。选哪个呢？为了我们大家的体力着想，又为了不辜负这些环海车道，我们硬着向前骑了1公里半，立马掉头往回骑了。可全没想到的是，往回走的路程，比我想像中的艰难得多！为什么骑来的时候轻松，回去时却难？为什么美丽的风景都变成了灰色的图案？为什么环保又高雅的自行车却变成了拖拉机一般？为什么邛海碧蓝的海水里面马上都散发着臭味？为什么金色的阳光变成了黑色？……我觉得我都快变成“十万个为什么”了，可心中的答案仍没出来，我陷入了沉思……。(原创投稿)
最终，我决定不想了，我要“重新做人”！再怎么想，还是要骑，不如一门心思在骑自行车上！虽说我累得不行，但我仍忍着，强忍着，任汗水湿透我的衣裳，任阳光烧烫我的皮肤，任这种信念在我的心中突破极限！这种信念超越了我的界，而这颗心带着身体超越了自行车界！我竟在体力不足之时，骑在了队伍的最前面！啊，我为这信念自豪，我为这信念骄傲！这种信念陪伴着我，骑了至少6公里多，骑回了老海亭。
后面的事情更是曲曲折折：我们去了河边，我的鞋却不小心打湿了；去吃了火盆烧烤，好多人都没吃饱，因吃不下去，而罪魁祸首却是我，是我提意去吃火盆烧烤的；晚上，又被“没面子”这词逼去送水果，还表达了骑车时关心的谢意……。
邛海，是让我超越心灵深处极限的地方！

青春是多姿多彩的：既有红色的激情，也有蓝色的'忧郁，既有粉色的梦幻，也有灰色的迷惘。——题记
有人说，青春是残忍的，因为它只有一次；也有人说，青春是美好的，因为它赋予了我们前进的动力。但我认为，青春是没有任何限制的，它无关性别，无关身份，更无关年龄。无论何时何地，只要我们的心中有星星激情的火种，它便可以在我们全身蔓延开来。
青春——初遇的开始！
老天爷对每个人都是公*的，它赋予了我们每个人一件异常珍贵的东西，那就是——青春！激情澎湃的青春，赋予了人们无限的遐想，使人们不由得对未来的美好憧憬多上几分。
青春——复杂的味道！
青春，就像……一杯红酒，表面诱人，实际则不然。当我们靠*时，喜悦、兴奋、激动等“味道”也随之而来；但当你渐行渐远时，才发现：原来，青春并不像你所想的那样，简单，纯洁……
青春，离别的伏笔！
天下没有不散的筵*。快乐的时光总是过得特别快。也正因如此，它才总是让人留恋。
青春，人生中最靓丽的一道风景！
青春，生命中不可或缺的一段旅程！
青春，会为我们的航行划上一个最完美的标点！
今天是个令人兴奋的日子，因为今天我们一(5)班的全体同学跟着老师去凤凰谷体验馆过了一把瘾。
来到体验馆，只见里面有各种各样的职业体验，有做护士的，有当主持人的，有做蛋糕的，也有当牙医的……我跟着大家来到牙医体验馆，同学们穿上牙医的白大褂还真像一个个小医生。这时，我看到一个假人躺在那，忍不住去摸了一下，哎呀，假人的脸居然是软的!我的心怦怦直跳，吓得都快跳出嗓子眼了。同学们一个个上前当起了医生，我也大着胆子凑上前，学着大家的样子把放大镜放进假人的嘴里仔细照了照，原来没什么可怕的嘛。牙医馆的阿姨还告诉了我们正确的刷牙方法，原来我坚持的横着刷的确是错的，回家后我要好好改改我的刷牙方法。
体验馆中让我们最为兴奋的'当然是明星走秀台了。同学们穿上蜘蛛侠、大鲨鱼、白雪公主等各种服饰大摇大摆地上了台，大家摆出了各种各样的姿势展示自己。我在哪?嘿嘿，你仔细看，那个穿着黑白斑点、一笑就露出缺颗大门牙的“奶牛”就是我!我可是“初生牛犊不怕虎”，一上场，我就楸住了旁边的“大老虎”的尾巴摆了个造型，“大老虎”也不介意，一个劲地冲我乐呢。“咔嚓”，胡老师抓住时机，让这一刻在相机里定了格。
接着，我又去搭了积木，体验了小主持人，还去尝试了一把当艺术家——画沙画……快乐的一天就这样过去了。
今天，是一个特别的日子；今天，是一个重要的日子；今天，是个高兴的日子；因为今天，我突破了自己的极限。
体育考试的第三项——400米跑，就在今天开始了。我们七班来到操场上，自由做热身活动，我压了压腿，跑了几步，为一会儿的400米做准备。
很快就轮到我们了。我站在起跑线上，腿有些发软，老师一声令下，我后脚尖一发力，冲了出去。我前面有不少人，陈子昊冲到了第一，其他人蠢蠢欲动，随时想拿下他，我不甘落后，用尽全部力气，才只跟上“大部队”的末端。没过一会儿，陈子昊慢了下来，张忆枫一举超越过去。我的'速度也渐渐慢了下来。
在大概跑了200米后，我的体力耗光了，腿像灌了铅一样重，比之前任何一次都累，我想走几步，可我不敢走，我害怕后面的人超过去，就一直以慢速跑着。没跑几步，嗓子也开始火辣辣的疼，忽然间，我有种自己马上就要倒下的感觉，前面的同学已经到终点了，我不能倒下，后面还有一些同学呢！我这样想着，用尽最后的力气冲刺，得了第八名。
在我写名字时，我发现自己跑了1分41秒，比起原来的1分51秒，足足快了十秒。这十秒，对我来说意义非凡，我知道了我自己是可以超过1分51秒的，是可以有所进步的。我的信心又重新燃了起来。
在这一次考试，我突破了极限，创造了新的记录。
——挑战极限作文500字（精选五篇）
俗话说得好：“分，分，分，学生的**;考，考，考，老师的法宝。”高分和低分的待遇那是绝对的不一样呀！
今天，晴空万里。“啊！”五年（9）班课室传来了一阵不满的声音，这声音打破晴空万里的宁静。原来，是宋老师要我们回家挑战一下爸、妈的分数极限。
嘻嘻！这场爱的极限结果怎样，我真期待。但是，话不能这样说，我从来没有考过66分的大低分，鸡毛掸子？鼓励？只有一线只差！“神仙呀！救救我吧！这主意可不是我想的，希望吉人天相啦！”我忐忑不安，不知自己的下场是残酷？还是原谅？
回到家，我火速做到厨房，闻到了一股火药味儿，“不是吧！”我害怕地说。妈妈看到我后大声说：“大人的事！小孩少管好！”天哪！爸妈的心情指数全线飘绿，不是好时机呀！如果现在说，那不是火上加油、雪上加霜嘛！不！不！不！还是先看好情况，等一下再说。吃饭时，爸爸认识了错误，向妈妈说了个对不起，妈妈随机怒为喜，啊！这还好，收市反弹！！但现在更不是好时机，妈妈刚刚破涕为笑，要是我现在气一下她，她那怒火反冲喉咙那怎么办好？还是让她多美几分钟。
嗒！嗒！嗒！似乎时钟也在鼓励我说：“怕啥！就66分嘛！让你父母看一下。”时钟不说我也没有那么害怕，它说了我更害怕。我拿着一张有红红两个大字的试卷，迈着沉重的脚步走到妈妈身边，拿那卷子给妈妈，妈妈拿到试卷第一个反应不是说打说骂，而是问了我两句话，“你尽力了吗？你知道自己低分的原因是什么吗？”我肯定地回答：“我尽力了，我也知道了自己低分的原因。”妈妈摸了摸我的头说：“没有一个天才没有失败过，失败过的人更有可能成为天才。我相信你能行！”
原来妈妈对我的爱是没有极限，是十全十美的爱。
今天是星期二，灿烂的阳光照得我心情舒畅。一大早，我邀上一些伙伴，兴高采烈地前往南屿的“森林之家温泉度假村”，体验户外运动——飞跃丛林。
到了目的地，我们先接受教练的培训。教练告诉我们安全带该怎么用：先是挂钩，它起到保护作用，防止我们从高空摔下。在攀爬过程中，会时不时有一些阻碍物，这时，挂钩就要从阻碍物上穿过，给探险增加了难度。再是滑轮，它是从绳索上滑过去的必备之物。介绍完各种工具的使用及注意事项后，我们就开始了体验征程。
挑战的项目有梅花桩、绳索、踏板、网兜、滚筒……其中最难的非梅花桩莫属，你看，我的脚刚踩上去，还没站稳，那一根根的柱子就调皮地上下摇晃，好像不想让你踩在它们身上。可是迈出了第一步就退不回来了，我只好鼓起勇气，按照教练教的方法来走：先用左脚踩在第二根圆木上，只能踩左半边，接着再用右脚踩在第二根圆木的右半边，依次类推，总算走完了梅花桩，我的身上都紧张地冒出了汗。看着下面，起码有两层楼那么高，我不禁有些后怕了。
吊绳也是一块难啃的骨头。我看着一根一根悬在空中、间隔很开的吊绳，顿时心中忐忑，行动犹豫了，脚一直迈不出去。“加油，不用怕，你一定行!你可是领头雁呀，后面还有三个哥哥在看你呢!……”听着家长们的打气、加油。我慌乱的心慢慢*静了下来，自信中夹杂着一点胆怯，迈出了第一步。
最好玩的是绳索了，这时滑轮就派上用场。先把它挂在绳索上，再把挂钩挂在滑轮凹进去的地方，双手抓紧两根粗线，双脚用力一蹬,顿时两脚悬空，身子似乎也如燕子一般飞起来,森林里的树木一棵棵在我眼前闪过,一眨眼功夫，就从这头"飞跃"到了那头，好刺激,难怪叫"飞跃丛林"呢。可惜路程太短了，我还没飞够就到了另一头，真想多飞机次啊!
最后，我们一起分享“飞跃丛林”之后的.胜利的果实——松果。那满地的松果吸引着我们向它们飞奔而去，刺激的一天结束了，我们带着一大袋松果踏上了归程。
今天，我挑战了极限，战胜了自我，我感觉自己高大了许多!
星期天，我和爸爸、妈妈一起去东台森林公园玩。
到了公园，我们先去买了门票，一进去看到大森林的美景，到处都是一颗颗参天大树，还有一眼看不到尽头的栈道。
我们沿着公路往里走，走着走着就到了一个小木桥，桥上竖着一个牌子，上面写着：猜猜这些树木的生长需要经过多少年才能形成这片树林呢？前方100米有答案！于是我迫不及待地飞奔过去，想一探究竟。一会我飞奔到了100米的距离处，一个竖在路边的牌子上写着答案：500年。
接着，我们去到了儿童乐园，一玩就忘记了时间，半个小时一眨眼就过去了。妈妈说：“12点了，我们去吃饭吧？”到了自助餐厅发现人超多，因为整个森林公园只有这一家餐厅，所有的游客都只能在这用餐。大家吃饭简直可以用抢的来形容，不到10秒，我就看到一锅白米饭被抢完了。可是我发现这样吃饭好开心，哈哈！
吃过午餐后，我们走了很长一段路，去到了探险乐园，光听名字你就可以知道有多不简单。这可比我以前玩过的室内游乐中心的项目难多了。我先爬到大概有四米高的一个塔台，先走过了一段钢丝，然后就来到了最最难的过滚木晃桥，每一脚踩上去脚下的木头都在转，手中的铁链更是摇摆不停，我的心都提到了嗓子眼。如果你踩过去就知道有多难，我真的不敢前进。最后在爸爸妈妈的不断鼓励下，我好不容易战胜自己的内心恐惧，顺利的踩过11根木头，进入下一关。等我完成全部的项目后，我数了一下，我总共完成了12个项目的挑战。
爸爸妈妈都夸我非常棒，如果是他们也不敢完成。今天的周末时光真的非常开心，我和爸爸妈妈一起踩着夕阳的余辉，漫步在森林的小道上，空气清新，心情愉快，森林公园真是个好地方。
熟悉我的人都知道，我是个怕高的女孩，超过三米，我就觉得很恐怖。
我家住在一楼，不用坐电梯，这让我大大舒了一口气。我所能挑战的极限就是三米，超过一毫米都不干。
周末，我和好朋友喻巧灵去义务欢乐岛水上乐园玩。我们玩了好几个项目，最高的也没超过三米。
又玩了一会儿，我觉得玩厌了，便想看看还有什么可以玩。
当我的目光捕捉到整个游乐园最高的滑梯时，我情不自禁地停下了。它的高度远远超过三米，我却莫名其妙地说了一句：“我们去玩那个吧！”
喻巧灵顺着我手指的方向看过去，欣然同意。我们一步一步登上梯子，登得越高，我心里的恐惧就越大。
终于，我们登到了顶上，四个出口敞开着，似乎在欢迎我们投入它的怀抱。此刻，我们却一点也不想下去，从这里往下面看显得格外恐怖。我们犹豫了，想下去又不敢，心底所有的豪言壮语在那一刻全都烟飞云散，一个也找不出。
我彻底抓狂了，不能下去也不能一直在这待着。可是我们谁也不敢滑下去，进也不是，退也不是，不知道怎么办。
我在心里不断地给自己打气：加油，勇敢地滑下去，就不会害怕了。我鼓起勇气，往下一滑，只感觉心脏像电梯一样往上升，简直要冲出喉管。随着坠地所发出的声音，“电梯”停电了，一下子返回原位。过了几分钟，喻巧灵也滑了下来。
挑战极限的那一刻，自豪感油然而生。是的，我为自己感到自豪。
举世瞩目的奥运会过后，残奥会也紧跟着来了。
晚上，我们全家坐在电视机前，观看开幕式。运动员进场后，一位盲人钢琴家在舞台中央缓缓地升了上来。他演奏的是《四季》。随着季节的变化，场景也不停地变幻着。春天是漫山遍野的桃花，粉红粉红，笑得多灿烂；夏天是开满池塘的莲花，白的雪白如白玉，绿的碧绿似翡翠，清清爽爽；秋天是一望无际的稻谷，黄得丰满，温馨，还带着几丝喜悦；冬天是铺天盖地的冰雪，雪，洁白无瑕，冰，晶莹剔透，形成了一个冰清玉洁的天地，粉装玉砌的世界，真是银装素裹，分外妖挠。接着，一个坐在轮椅上的女孩和一群聋哑少女出现了。坐在轮椅上的女孩叫李月，在四川特大地震中失去了一条左腿。李月头戴一个五彩斑澜的花环，身穿一件雪白的连衣裙，仿佛是一个活泼快乐的白精灵。少女们用自己的手做成脚，跳起芭蕾舞，小李月也做出一个又一个的芭蕾手位，她那高贵的神情仿佛是一位美丽的小天鹅公主。这时，芭蕾王子来了。他与小李月一同翩翩起舞，亮出一个个漂亮的造型。然后，场景换成了宝蓝色的“湖面”。突然，湖面上浮起几只鸟儿，原来是和*鸽、天鹅和雪雁。和*鸽们互相追逐嬉戏，雪雁们相互梳理羽毛，而天鹅们则欣赏着自己美丽的倒影。这水真蓝啊，若不是有鸟儿，你一定会以为这湖是一块硕大的珍贵蓝宝石。音乐由优雅空灵、温柔甜美变为热烈急促，鸟儿们的流动也越来越快。当音乐以裂帛之音结束时，藏在“湖底”的演员们站了起来。真是一幅人与自然相融的完美画卷！
残疾人们用他们残存的躯体挑战生命的极限，因而我觉得，残奥会比奥运会更加令人感动，更加值得人钦佩！
