解题思路：设MN长为x，根据题意构造直角三角形，利用其公共边构造方程求解．

设MN长为x米，则ME=（x-1.6）米，
∵β=45°，
∴DE=ME=x-1.6，
∴CE=x-1.6+29.6=x+28
∵[ME/CE＝tanα＝tan40°＝0.8，
∴
x−1.6
x+28]=0.8，
解得：x≈120．
故迪恩•波特此次高空走扁带的架设高度约120米．

点评：
本题考点： 解直角三角形的应用-仰角俯角问题．

考点点评： 本题考查仰角的应用：要求学生借助仰角关系构造直角三角形，并结合图形解三角形设计测量方法．

hello everyone ,i am glad to make a presentation here.my topic is my dream .I want to be a excellent adventurer when I was child.I believe that adventure is meaningful affair .I dream of of one day travelling arcoss every corner of the world and then write all of experiences into my memoirs.that must be very interesting !

鲁滨逊是一个敢于冒险、性格坚毅、勇于追求自由自在、无拘无束生活的硬汉子。

我们所说的智慧,不是作家写小说似的胡乱编一通,而是真正明白人生哲理并能真正把握自己的

勇气只是成功过程中的一个词!不知道你想知道什么!要是走完你的成功之路的话,我用几个词连起来表达下：你的健康+目标+时间+地利+人和+自信+勇气+不言弃+头脑=成功!
给你纠正下：冒险家的作为不能只用用勇气来概括,也不是蛮干,他们比我们说的成功要付出的更多,因为他们压上了生命!

体育所展现的勇气不是冒险家(轻率)的蛮干,而是(慎重)的深思熟虑.

第一,披作文化外衣的那些所谓的君子——学者,汉学家,考古家,冒险家,并不都是真的君子.他们往往包藏祸心
第二,再坚固的文化,也可能在小人的手中断送了前程.文化的脱节可能导致遗憾千年,也可能导致民族蒙羞.

不能,没有实战经验.要成为探险家或冒险家,光有理论知识是不行的.个人觉得必须要受到过正规的培训才行!

Adventurer Fossett launches solo balloon trip (2001/08/08)
US adventurer Steve Fossett on Sunday launched his balloon from the Western Australian desert in another attempt to become the first to fly a balloon solo around the world.
US millionaire adventurer Steve Fossett's balloon is inflated by his ground-crew under a full moon in the township of Northam,located 100 kilometres east of Perth in Western Australia,August 5,2001.Fossett is near lifting off for his sixth attempt to complete the first solo circumnavigation of the Earth.[Reuters] The giant high-altitude balloon,bathed in the desert's golden morning light,drifted slowly into the sky above Northam,a small mining town 100 km (62 miles) east of Perth,just after 7.00 a.m.(2300 GMT).
Fossett had delayed inflating the aircraft for six and a half hours due to unfavourable winds,but with time running out before the arrival of the morning's hot thermals,he gave the order to fill the balloon with helium for a dawn launch.
Fossett waved to around 100 townsfolk as he entered the capsule for an eastward circumnavigation that he expects will take 15 days.
"I am a bit nervous about the first night," Fossett said before take-off.
"On the first night I will find out if everything works,if there are any leaks in the balloon,if there are any failures in communications and if the all-important heating works," he said.
The millionaire former stockbroker has made a series of failed attempts to fly solo in a balloon around the world.
The last attempt to inflate the giant balloon for a launch on June 17 from the Australian gold mining town of Kalgoorlie ended in disaster when a freak wind tore it apart.
Fossett's fourth solo bid ended in near disaster in 1998,when a thunderstorm off Australia's northeastern coast shredded his canopy and sent him plummeting 29,000 feet (9,000 metres) into the Coral Sea.He was unhurt.
This year Fossett,57,decided to launch in western Australia,some 600 km (400 miles) from the Indian Ocean,to have a better chance of avoiding thunderstorms in the South Pacific and gain time to detect problems while still over land.

我也初一的，老师讲过的，肯定对的。

解题思路：明确重力的三要素，大小、方向、作用点，再按照作图的要求画出人受到的重力．

冒险家Brian Mosbaugh所受的重力作用在重心，方向竖直向下，如图所示：

点评：
本题考点： 重力示意图．

考点点评： 画力的示意图，就是用一条带箭头线段表示出力的三要素，所以要先正确分析力的大小、方向和作用点，再根据力的示意图的要求作出力的示意图．
