Vision
Human vision like that of other primates(灵长类) has evolved in an arboreal(丛林) environment. (46)
In the course of evolution, members of the primate line have acquired large eyes while the nose has shrunk. (47) Of mammals(哺乳动物) only humans and some primates enjoy color vision. (48) Horses live in a single-color world.
Light visible to human eyes, however, occupies only a very narrow band in the whole electro magnetic spectrum(光谱). Ultraviolet rays(紫外线)are invisible to humans though ants and honey bees are sensitive to them. (49) The world would look terribly different if human eyes were sensitive to infrared radiation(红外线). Then instead of the darkness of night, we would be able to move easily in a strange shadow less world. (50)
The color sensitivity of normal human vision is rarely surpassed even by complicated technical devices.
A. Humans have no direct perception of infrared rays.
B. In the dense complex world of a tropical forest, it is more important to see well than to de velop an acute sense of smell.
C. That gives the eye a wilder view.
D. The red flag is black to the bull.
E. There are different mammals in tropical forest.
F. In this world, objects glowed with varying degrees of intensity.
选项
答案
D
解析
空格的前一句说只有人和一些灵长目动物能够分辨颜色;后一句说马生活在一个单色的世界里。选项D和Horses live in a single-color world. 并列,是另一个说明只有人和一些灵长类动物才能分辨颜色的例子。
