Most of Earth’s surface is ocean. The ocean floor is inaccessible for extensive research without equipment of greater technological sophistication than is currently available. It must therefore be true that scientists know less about the ocean floor environment than about almost any other environment on Earth. Which of the following, if true, provides the most support for the conclusion?
选项
A、Many mountain ranges lie entirely beneath the ocean surface, yet new underwater surveying equipment has produced three-dimensional charts of them that are as accurate as those available for mountain ranges on land.
B、Strong water currents circulate on the ocean floor, but the general pattern of their movement is not so well understood as is the pattern of air currents that circulate over land.
C、In contrast to most land environments, temperature conditions at the ocean floor are generally stable and uniform, since sunlight does not penetrate far below the ocean surface.
D、Very few people have seen detailed maps of extended regions of the ocean floor, even though such maps are available in almost all large libraries.
E、Animals living on the ocean floor must be able to withstand water pressure that is far greater than the atmospheric pressure with which land animals live.
答案
B
解析
本题让我们支持结论,结论的重点关键词为“Ocean floor”,选项(B)、(E)中有此关键词。(B)说明由海底的水流不易于被理解而支持了结论,“海底环境的了解一定比其他环境少”。所以(B)正确。(A)反对,(C)、(D)、(E)均为无关选项。
