Passage 5

(湖南省长沙市一中2010届高三第九次月考)

A recent experiment held in Japan shows that it is almost impossible for people to walk exactly straight for 60 meters. Tokyo University of Agriculture and Technology found 20 healthy men and 36 them to walk as straight as possible to a target 60 meters away at normal speed. Each man had to walk on white paper fixed flat to the floor wearing wet colored socks. The footprints revealed that all walked in a winding　 　37 　　straight line. Researchers found that people 　38 the direction of walking every few seconds. The amount of the winding differed from subject to subject. This suggests that 　39 　of us can walk in a strictly straight line. We walk in a winding way mainly because of a slight structural or functional imbalance of our limbs. 40　 　we may start walking in a straight line, several steps afterwards we will have changed the direction.

41 helps us to correct the direction of walking and leads us to the target. Your ears also help you walk.After turning around a lot with your eyes closed, you can hardly stand still, 　42 　walk straight. It’s all because your ears help you balance. Inside your inner ears there is a structure which contains liquids. On the sides of the organ are many tiny hair-like structures that move around as the liquid 　43 . When you spin, the liquid inside also spins. The difference is that when you 　44 , the liquid continues to spin for a while. Dizziness is the 45 of these nerves in your inner ears. When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will 　46　 　your ears more, thus you walk in a 　47 　line.
