听力填空
本听力材料来自于老托partb，partc，是公认实施有效的听写材料，对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃！
Nopain, no gain.我们的安排是这样的，第一遍用听力软件精听材料（建议做单句听写，听写的时候不要偷看我给的挖空题），然后按照我给的挖空题填关键词，回复后即可看到听力原文和文章精解，我将把难点和易错点oneby one 分析给大家。
回复填空答案格式如下：1____2____3____...et.al.
Not long ago, some of you may have read about a team of mountain-climbing scientists who helped to ______ the ______ of the highest mountain in the world: Mt. Everest. Of course, the elevation of Mt. Everestwas determined many years ago, using traditional surveying methods. But these scientists wanted to make a more precise measurement using a new method that ______recent advances in technology. It's called the ______. The Global Positioning System uses 24 satellites that circle the Earth. Each of these satellites is constantly sending out signals. And each signal contains important information that can be used to determine the ______ , ______, and elevation of any pointon the Earth's surface. Well, in order to use this system to calculate Mt. Everest's elevation, scientists needed to put a special ______ on its ______ to receivesignals from the satellites. The problem with this was that, in the past, the receivers were much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of a handheld telephone, soclimbers were able to take a receiver to the top of Everest and, from there, to______ the satellite system signals that would allow them to determine the precise elevation. And it turns out that the famous peak is actually a few feet higher than was previously thought.

Not long ago, some of you may have read about a team of mountain-climbing scientists who helped to recalculate the elevation of the highest mountain in the world: Mt. Everest. Of course,the elevation of Mt. Everestwas determined many years ago, using traditional surveying methods.
But these scientists wanted to make a more precise measurement using a new method that takes advantage of recent advances in technology. It's called the Global Positioning System.
TheGlobal Positioning System uses 24 satellites that circle the Earth. Each of these satellites is constantly sending out signals. And each signal contains important information that can be used to determine the longitude, latitude,and elevation of any point on the Earth's surface.
Well,in order to use this system to calculate Mt. Everest'selevation, scientists needed to put a special receiver on its summit to receive signals from the satellites. The problem with this was that, in the past, the receivers were much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of a handheld telephone, so climbers were able to take a receiver to the top of Everest and, from there, to access the satellite system signals that would allow them to determine the precise elevation. And it turns out that the famous peak is actually a few feet higher than was previously thought.

不久前，你可能已经读过一些关于帮助重新计算在世界上最高的山峰海拔登山科学家团队：山。珠穆朗玛峰。当然，山的海拔高度。珠穆朗玛峰是很多年前，使用传统的测量方法确定。
但是，这些科学家们想做出更精确的测量，采用一种新方法，在最近的技术进步的优势。它被称为全球定位系统。
全球定位系统使用24颗卫星绕地球。这些卫星不断发送信号。和每一个信号包含重要的信息，可以用来确定对地球表面的任何一点的经度，纬度，海拔。
好吧，为了使用这个系统来计算山。珠穆朗玛峰的海拔高度，科学家需要把一个特殊的首脑会议，以接收来自卫星的信号接收器。这个问题是，在过去，接收机是过于沉重的登山进行。但现在这些接收器已减少到手持电话的大小和重量，因此登山者能够采取珠峰顶部的接收器，并从那里访问，使他们能够确定准确的卫星系统信号海拔。它原来是著名的高峰，实际上比以前认为的高出几英尺。
祝大家每天进步一点点！
