A. begun to change in the opposite direction B. been weakening in strength for a long time C. caused the changes on the polarities D. misguided many a man and animal 相关知识点: 试题来源: 解析 B 正确答案:B 解析:文章第一段:《纽约时报》上周报道地球磁场严重减弱开始于150年前。磁场保护...
解析 B 正确答案:B解析:本题考查考生的理解能力,根据原文内容“During a reversal,the main field weakens, almost vanish-es,and reappears with opposite polarity.”在反向运转时,主要的磁场就会减弱,几乎彻底消失,甚至重新出现相反的磁极。根据这句话可以知道,地球磁场开始向它的反方向改变,所以B比较符合题意。

Earth’s magnetic field is often visualized as a powerful dipolar bar magnet at the center of the planet, tilted at around 11° to the axis of rotation. However, the growth of the South Atlantic Anomaly indicates that the processes involved in generating the field are far more complex....
If you find it hard to imagine, there’s afilm in 2003which showed what can happen when the Earth’s magnetic field is breached. Electrical storms, nonstop bombardment of solar flares, super-strong earthquakes. It’s a bleak scenario and it might be closer to reality than we think. ...
