问题     Man has become master of the earth’ s surface. He is constantly probing into the earth’ s depths and into the atmosphere’ s upper reaches. Yet it is doubtful whether man, with ’all of his intelligence and vigor, holds his planetary seat with greater assurance than a vast tribe of small, many-legged animals that pass their lives at his feet--the spiders.
    Spiders are among the miracles of science. They dwell at higher altitudes than any other creature their size or lager. On the slopes of Mount Everest, at an altitude of twenty-two thousand feet-- five thousand feet above the vegetation line--lives a species of black spider only a quarter of an inch long. This is an incredible environment for creatures so delicately constructed. To protect themselves from the chill of night, they take shelter in crevices where the twenty-four-hour variation in temperature is only twelve degrees, as against forty-four on the outside.
    Spiders inhabit others unlikely places--rabbit burrows, flowers, anthills, and the desolate, drafty aeries of eagles. They have been found soaring through the air five miles above the earth. One species has been discovered in an African cavern move than two thousand feet underground. [br] The author thinks that spiders ______.
选项 A、rival man as master of the earth
B、are as firmly established on the earth as man
C、are more vigorous than man
D、are more firmly established on the earth than man
答案 D
解析 第一段提到it is doubtful whether man．．．  holds planetary seat with greater assurance than the spiders，作者对人类比蜘蛛更适应地球环境表示怀疑，后面又提到了蜘蛛怎样在恶劣的环境下生存，因而得知蜘蛛比人类更firmly established on the earth。
