When light illuminates an object, part of it is absorbed and part reflected, the ________lightness of an object depends on the proportion of light that is reflected.
选项
A、denoted
B、embodied
C、insulated
D、perceived
答案
D
解析
动词辨义。光线部分被吸收部分被反射,而被反射的那部分之所以知道反射回来了,就是因为能被人们察觉到,perceive意为“觉察”,如:perceive by the nose(用鼻嗅出),符合题意。denote意为“所指”,如:A flashing yellow light denotes caution.(闪烁的黄灯表示警告。)embody意为“体现出来的”,如:laws that embody a people’s values(加入了体现人的价值的法律);insulate意为“绝缘,隔绝”,如:The language lab is well insulated against noise.(语音室隔音很好。)
