【单选题】The early warning systems developed in the 1990's are used to


A．improve estimates of long-term earthquake probabilities.
B．tell people in the epicenter when the earthquake will come.
C．allow evacuation from the region that the earthquake will hit.
D．prepare people for earthquakes several minutes in advance.


网考网参考答案：D
网考网解析：
90年代发展起来的预警系统通过监测地震开始后的活动，“to warn people farther from the epicenter．．．；to create early warning systems to notify people that a large earthquake has begun，from a few seconds to minutes in advance．”A说能提高地震长期预报的准确率，其内容不符事实。B说告诉在震中的人们地震何时来，这与上面的原文相矛盾。C说让人们从即将遭受地震袭击的地方撤出。这是不可能的，因为预报只能提前几秒钟或几分钟，撤出显然是来不及的。D说让人们提前几分钟准备地震的到来。这与上述原文较接近。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
