Our ape-men forefathers had no obvious natural weapons in the struggle for survival in the open. They had neither the【C1】________teeth nor the strong claws of the big cats. They could not【C2】________with the bear, whose strength, speed and claws【C3】________an impressive "small fire" weaponry. They could not even defend themselves by running【C4】________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【C5】________to failure and extinction.
But they were【C6】________with enormous concealed advantages of a kind not possessed by any of their competitors. In the search【C7】________the pickings of the forest, the ape-men had【C8】________efficient stereoscopic vision and a sense of color that the animals of the grassland did not possess. The ability to see clearly at close【C9】________permitted the ape-men to study practical problems in a way that lay far【C10】________the reach of the original inhabitants of the grassland.
Good long-distance sight was【C11】________another matter. Lack of long-distance vision had not been a problem for forest-dwelling apes and monkeys because the higher the【C12】________the greater the range of sight, so all they had to do was climb a tree out in the open. However, this simple solution was not【C13】________Climbing a hill would have helped, but in many【C14】________the ground was flat. The ape-men【C15】________the only possible solution. They reared up as high as possible on their hind limbs and began to walk upright. This vital change of physical position brought about【C16】________disadvantages. It was extremely【C17】________and it meant that the already slow ape-men became slower still. 【C18】________, they persevered and their bone structure gradually became【C19】________to the new, unstable position that【C20】________them the name Homoerectus, upright man.

选项
A、progressed
B、generated
C、developed
D、advanced
答案
C
解析
progress意为“进展,进步”,是不及物动词;generate意为“产生,造成”;develop意为“(逐渐)形成,(逐渐)获得”,可与interest、relationship、ability等搭配;advance意为“促进,提出,提升”。根据句意“猿人________了有效的、草地动物所不具有的立体视觉和颜色辨别能力”可知,C最符合文意。
