The human eye is mucxu* scj3xm7 w/ w3 ja+q+wqs7ph like a camera — yet, when a camera shutry5u,m2f5kk, k;zl+hair 1 n lter is left open and the camera is moved, the image will be blurred; but when you move your head with your eyes opemza,12 i5 rkr+kk;lh ul,fny5n, you still see clearly. Explain.
参考答案: You can
leave your eyes open while you are moving your head and still see clearly
because your brain “refreshes” the image from the retina about 30 times a
second. In other words, your brain and
your retina work together in a manner similar to how a motion picture camera
and film work together, which is not at all like how a still camera and film
work together.
