Very high waves are destructive when they strike the land. Fortunately, this seldom happens. One reason is that out at sea, waves moving in one direction almost always run into waves moving in a different direction. The two sets of waves tend to cancel each other out. Another reason is that water is shallower near the shore. As a wave gets closer to land, the shallow bottom helps reduce its strength.
But the power of waves striking the shore can still be very great. During a winter gale, waves sometimes strike the shore with the force of 6, 000 pounds for each square foot. That means a wave, 25 feet high and 500 feet long it face, may strike the shore with a force of 75 million pounds.
Yet the waves, no matter how big or how violent, affect only the surface of the sea. During the most raging storms, the water a hundred fathoms(600 feet)beneath the surface is just as calm as a day without a breath of wind.
From your reading of the passage, which of the following is true? ______.
选项
A、At a depth of 1200 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 raging 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 floor
答案
B
解析
本题为段落理解题。第3段大意为:无论海浪多么巨大、猛烈,也只能影响到海面,而海面以下600英尺的海水会非常平静。细读4个选项,只有B是正确的(潜水员在水下700英尺驾驶的船只不会受到海面风浪的影响)。
