The pleasures which a movie offers to our eyes have been paid for with the loss of sight of a man whose name is hardly known outside the annals (年报) of science—Joseph Plateau, a Belgian professor, born in Brussels in 1801.
He studied the mechanism(机制) of sight, beginning a series of most dangerous experiments at the age of 28 by staring into the sun for 25 seconds to see what the effect on his eyes would be. He was blind for nearly a month. But he went on experimenting, increasing the length of time during which he looked into the sun, knowing that in the end this would cost him his sight. At the age of 42 he was completely and incurably(治不好地) blind; the sun had destroyed the retina (视网膜) of his eyes. But he continued to work as well as he could until he died at the age of 82.
Science profited enormously(巨大地) from his research. He studied the so-called "inertia of the eye(视觉暂留)" which makes a picture remain on the retina for about one-sixth of a second after it has disappeared from our vision. This means that, if we see a succession of individual pictures each of which appears only for a fraction of a second, they "overlap" in our brain; and if they show consecutive (连贯的) phases of movement, that movement will appear to us to be continuous.
A picture remains on the retina for______.
选项
A、6 seconds
B、1 second
C、16 seconds
D、1/6 of a second
答案
D
解析
事实细节题。从文章第三段第二句“…a picture remain on the retina for about one—sixth of a second…”可知,一个画面可以在视网膜停留的时间是一秒的六分之一,所以本题的正确答案是D。
