Man has become master of the Earth’s surface. He is constantly probing into the earth’s depths and into atmosphere’s upper reaches.【C1】______ it is doubtful whether man, with all of his intelligence and vigor, holds his planetary seat with greater【C2】______ than a vast tribe of small, many-legged animals that pass their lives at his feet—the spiders.
Spiders are among the【C3】______ of science. They dwell at higher altitudes than any other【C4】______ of their size or larger. On the slopes of Mount Everest, at an altitude of twenty-two thousand feet—five thousand feet above the vegetation line—【C5】______ a species of black spider only a quarter of an inch long. This is an【C6】______ environment for creatures so delicately constructed. To protect themselves from the chill of night, they take shelter in crevices where the twenty-four-hour【C7】______ in temperature is only twelve degrees, as against forty-four on the outside.
Spiders live in other unlikely【C8】______ —rabbit burrows, flowers, anthills, and the desolate, drafty aeries of eagles. They have been found soaring through the air five miles【C9】______ the earth. One【C10】______ has been discovered in an African cavern more than two thousand feet underground. [br] 【C5】
选项
A、live
B、lived
C、living
D、lives
答案
D
解析
本题要求填入谓语动词的适当形式。本句是个倒装句,主语为a species of blackspider。species(种,类)一词单复数同形,但在本句中是单数,因此谓语动词也应该用单数形式,D项lives为正确答案。整段文章的时态都是一般现在时,故本句中不可能出现一般过去时,因此B项不正确。
