问题 According to the passage, destruction caused by high waves occurs ______.
From your reading of the passage, which of the following is tree?
选项 A、At a depth of 1,200 feet the effects of a violent surface storm are frightful.
B、A submarine commander navigating his vessel at a depth of 700 feet will not be affected by a ranging surface storm.
C、A typhoon 500 miles out at sea can stir up the ocean floor.
D、If high waves can strike the shore with a horizontal force of 75 million pounds, the vertical force of such waves can have an even greater effect upon the ocean floor.
答案B
解析 本题为判断题。A项意为海面狂风巨浪给1,200英尺海深处带来的影响非常可怕；C项为海面上空500米的台风能够搅动海底；D项为如果海浪以7,500万磅的水平力冲击海岸，那么它的垂直力会对海底产生更大的作用。此三项均说明海面风浪会影响海底，这与文章最后一段"the water a hundred fathoms(600 feet)beneath the surface is just as calm as on a day without a breath of wind．"中的关键词"calm"相违背。B项"指挥官坐在处于700英尺海底深处的潜水艇上，不会受到海面巨浪的丝毫影响"与文意最相符。
