Now I have carefully cropped this sequence to be exactly the duration of a human eye blink, so in the time that it would take you to blink your eye, the fly has seen this looming predator, estimated its position, initiated a motor pattern to fly it away, beating its wings at 220 times a second as it does so.
我小心地裁剪了这个片子 使得它跟人的眨眼时间一致 使得当你眨眼的时候 这个苍蝇已经看到了捕食者 估计好了它的位置，启动了飞行模式 以每秒220下的速度拍打着翅膀
