[单项选择]Passage Three

Experienced baseball fielders can tell how far a ball is going to travel just by listening to the crack of the bat. If they didn’t, they wouldn’t stand a chance of catching it, claims a physicist in New York. "When a baseball is hit straight at an outfielder, he cannot quickly judge the angle of the scent and the distance the ball will travel," says Robert Adair, a physicist at Yale University. If he relied purely upon visual information, the fielder would have to wait for about one-and-a-half seconds before he could tell accurately if the pitcher hit the ball long or short. By this time the ball may have travelled too far for him to reach it in time. To stand a fighting chance of catching it, according to Adair, fielders must listen to the sound the ball hitting the bat to judge how far it will travel. There is anecdotal A. Because it may take longer time for him to exert judgment. B. Because the ball may change directions during flight. C. Because the ball may be hit either long or short. D. Because light travels faster than sound. 查看答案 更多"Passage Three Experienced"的相关试题: [单项选择]Passage Three Experienced baseball fielders can tell how far a ball is going to travel just by listening to the crack of the bat.
