Our ape-men forefathers had no obvious natural weapons in the struggle【C1】________ survival in the open. They had neither the powerful teeth nor the strong claws of the big cats. They could not【C2】________ with the bear, whose strength, speed and claws provided an impressive "small-fire" weaponry. They could not even defend themselves【C3】________ running swiftly like the horses, zebras or small animals. If the ape-men had attempted to compete on those terms in the open, they would have been doomed to【C4】________ and extinction. But they were endowed with enormous concealed advantages of a kind not possessed by any of their competitors.
In the search for the pickings of the forest, the ape-men had【C5】________efficient stereoscopic vision and a sense of colour that the animals of the grasslands did not possess. The ability to see clearly at close range permitted the ape-men to study practical problems in a way that lay far beyond the reach of the original inhabitants of the grassland. Good long-distance sight was【C6】________ another matter.
Lack of long-distance vision had not been a problem for forest-dwelling apes and monkeys because the higher the viewpoint, the greater the【C7】________ of sight—so what they had had to do was climb a tree. Out in the open, however, this simple solution was not available. Climbing a hill would have helped, but in many places the ground was【C8】________. The ape-men adopted the only possible solution.

However, they persevered and their bone structure gradually became adapted to the new, unstable position that【C10】________ them the name Homo Erectus, upright man. [br] 【C5】
选项
答案
I
解析
空格前的had提示,空格处应填入过去分词构成过去完成时。空格前提到“为了寻找森林中可以采摘的东西”,可推断此处表示“猿人开发培养了立体视觉和色感”,developed能表示“自身潜在技能的开发”,故选I。generated意为“产生”,从下一句的The ability to see clearly at close range“能够看清近距离的物体”可以推知,猿人本来是有视觉的,故不选“产生”。
