在托福的阅读准备中，相信大家都能感受到，如果在平时能够多多积累一些与阅读有关的背景资料，这样如果碰到相关话题的文章时就可以心中有数，也就可以大大提高阅读答题的正确率了。那么，在以下内容中，我们就为大家带来托福阅读的一些相关背景资料，希望能为大家的托福备考带来帮助。
Beware first-class travellers! Passengerssitting in the rear of a planehave the best chance of survival in the event ofa crash, an extraordinary andcostly aviation experiment ever conducted hasrevealed.
头等舱的乘客要当心了!一项耗资巨大的特别飞行试验揭示，在坠机事故中生还机会最大的是坐在飞机尾部的乘客。
In a unique aviation experiment recently,the 170-seat Boeing 727 was madeto crash in a controlled manner in a remotepart of Mexico's Sonoran Desert.
在近日开展的一项独特的飞行试验中，一架有170个座位的波音727飞机被控坠落在墨西哥索诺拉沙漠的一个偏远地带。
After pilot James Slocum parachuted out ofthe plane at 2,500ft, the jetwas guided into the ground by a pilot in afollowing Cessna via a remote-controldevice, the reporters reported.
据报道，在飞行员詹姆斯`索罗克姆于2500英尺高空跳伞离开飞机后，后面跟着的赛斯纳飞机上的一名飞行员用遥控设备操纵飞机向地面降落。
On board the jet were three sophisticatedcrash-test dummies designed tomove like humans.
试验飞机上有三具精密的坠机测试专用人偶，这些假人的四肢可以像真人一样移动。
They were arranged in three positions: onein the classic brace and wearinga seat-belt; one belted but not in the braceposition; and one neither beltednor in the brace.
它们以三种姿势摆放：一个人偶用标准方式系紧安全带，一个人偶扣上安全带但没系牢，还有一个人偶完全没有系安全带。
After the jet hit the ground nose-first,experts found that the dummy inthe brace position would have survived theimpact, the one not in the bracewould have suffered serious head injuries, andthe dummy not wearing a seat-beltwould have perished.
在飞机以头朝地的形式坠落到地面后，专家发现，安全带系得很紧的人偶会逃过坠机这一劫，松松地系着安全带的人偶头部会严重受伤，没有系安全带的人偶会毁掉。
Using this, experts predicted that 78percent of passengers on board wouldhave survived the impact, but that comingdown nose-first, all the first-classtravellers would have died because thefront of the fuselage sheared off.
根据这一试验结果，专家预测，78%的飞机乘客会生还，但因为飞机是头朝下落地，所以所有头等舱的乘客都会死亡，因为机身前端被削掉了。
Those sitting at the back would have hadthe best chance of survival.
那些坐在飞机尾部的乘客生还机会最大。
The 1 million pound project, to be screenedon Channel 4 next month, aimedto recreate a serious but survivable incident andallow scientists to study thecrashworthiness of the aircraft's frame and cabin,as well as the impact on thehuman body.
这一耗资100万英镑的试验项目将于下个月在第四频道播放。该项目的目的是通过再现一场严重但有生还机会的坠机事故，让科学家研究飞机机架和机舱的耐撞性能，以及坠机对人体的影响。
It is also hoped that the findings may helpincrease the chances ofpassengers surviving such a crash in the future.
研究人员还希望这些研究结果能有助于提高未来这样的坠机事故中乘客的生还几率。
The Boeing was packed with dozens ofcameras to record the impact from theinside. Footage was also collected on theground, in chase planes, and even fromthe ejecting pilot's helmet.
这架波音飞机上安装了几十个摄像机，从飞机内部来记录坠机影响力。地面上、跟踪的飞机、甚至跳伞飞行员的头盔内也安装了摄像头来采集视频。
