Exercise 35,7

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.


7. Which of the following, if true, provides the most
support for the conclusion?
(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.

逻辑题
题目要求找出进一步支撑文章的论点，那么首先一个找出文章的论点即最后一句. It must therefore be true
that scientists know less about the ocean floor environment than about almost any other environment on Earth.
那么要支撑的话就从要进一步来说明了解ocean floor的难度
A 支出新的设备能更好的的探测海底的mountain rage，即ocean floor，反
B ocean floor 的water currents 由于受到air currents的影响无法深入了解，可以
c ocean floor的temperature condition 平稳，反，未能突出难度
D 很少有人看过ocean floor的map，无关
E ocean floor的动物比陆地动物更能抗压，无关
