1 agree with pumpkin a) defending a revolutionary theory about the causes of earthquakes and methods of predicting them
(1)defending 有问题; (2)即使defending勉强讲的过去,这个理论是关于地震产生的原因吗??I don't think so. 2 do not agree on one hand, 请看原文 Most earthquakes had a small area of intense shaking, which weakened rapidly with increasing distance from the epicenter, 对应 more common的 shallow events很快就weaken了,说明shallow events不可能:S waves from an earthquake arrive at a given location long after the P waves 所以long interval只能是deep event。 on the other hand, 如果是deep event的话,它的interval也是很长的,所以c肯定错。 |
