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.
Now, you've been reading articles about the tremendous damage done to life and property by earthquakes.That's why ______ have been working so hard to develop methods of earthquake ______.We can now predict earthquake [assertively] fairly well, but the predictions only locate potential areas of danger. They don't predict the specific time and location at which an earthquake is likely to occur. Today I want to introduce to you three prediction models that have been developed.
The first prediction model looks along earthquake fawlts, those ______ in the Earth's ______,to find what are known as seismic gaps. Seismic gaps are places where the ______has shown little or no ______ activity for a long time. This theory ______ that such places are due for a major shock.
The second model relies on phenomena --- like ground flit. Using long ______ tubes containing water, observers noted that ground tilt tended to occur before major earthquakes. That led them to correctly predict the big Haicheng [HI CHUNG]quake of 1975 --- the first successful earthquake prediction scientists have ever made. A million people were ______ from that Chinese city before the earthquake struck. Unfortunately, this method hasn't worked ______, so we can'tsay it's been perfected.
The third modelis based on the theory that major earthquakes closely follow a series of minorones. Starting with the measurements and timing of the smaller quakes, acomplex ______ calculates the "times of increased probability" of amuch larger quake. Right now, this method, like the first method, cannotpredict specific times and places, but that may change as it is further developed.
For the moment, none of these models can predict with reasonable levels of confidence.
