　　听力填空

　　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.【填空答案】

　　Now, you've beenreading articles about the tremendous damage done to life and property by earthquakes.That's why seismologists have been working so hard to develop methods ofearthquake prediction. We can now predict earthquake [assertively] fairly well,but the predictions only locate potential areas of danger. They don't predictthe specific time and location at which an earthquake is likely to occur. TodayI want to introduce to you three prediction models that have been developed.

　　The firstprediction model looks along earthquake fawlts, those cracks in the Earth's crust,to find what are known as seismic gaps. Seismic gaps are places where the faulthas shown little or no seismic activity for a long time. This theory postulatesthat such places are due for a major shock.

　　The second modelrelies on phenomena --- like ground flit. Using long cylindrical tubescontaining water, observers noted that ground tilt tended to occur before majorearthquakes. That led them to correctly predict the big Haicheng [HI CHUNG]quake of 1975 --- the first successful earthquake prediction scientists haveever made. A million people were evacuated from that Chinese city before theearthquake struck. Unfortunately, this method hasn't worked consistently, so wecan't say 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 formula 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.

　　【参考译文】

　　现在，您一直在阅读有关地震造成生命和财产巨大损失的文章。这就是为什么地震学家一直致力于大力发展地震预报方法的原因。现在，我们可以相当不错地预测地震[自信]，但预测只找到潜在的危险地区。他们不预测地震可能发生的具体时间和地点。今天，我想向你介绍3个已开发的预测模型。

　　个预测模型看起来沿地震fawlts的，那些在地球的地壳裂缝，找到什么是地震空白。地震差距故障已经很长一段时间，很少或根本没有地震活动的地方。这个理论认为，由于这些地方都是一个重大的冲击。

　　第二种模式依赖现象---一样地掠过。长期使用含有水的圆柱形管，观察家指出，地面倾斜，往往会发生在大地震之前。这导致海啸---1975年的次成功的地震预报科学家曾经作出正确预测。从地震发生之前，中国的城市万人被疏散。不幸的是，这种方法并没有一致奏效，所以我们不能说，它已经完善。

　　第三种模式是基于理论的大地震，紧跟了一系列轻微的。测量和小地震的时间开始，一个复杂的公式计算的一个更大的地震“的概率增加的时代”。眼下，这种方法，和种方法一样，无法预测具体的时间和地点，但可能会改变，因为它有了进一步发展。

　　就目前而言，没有模型可以很有信心地合理地作出预测。
