问题    Can you walk a straight line? The question is much more difficult to answer than you think. A recent experiment held in Japan shows that it is almost (47)______ for people to walk exactly straight for 60 meters. Each man had to wear socks soaked with red ink and walk on white paper fixed (48)______ to the floor. The (49)______ showed that all walked in a winding rather than a straight line. Researchers found that people (50)______ their direction of walking regularly. However, the range differed from subject to subject.
This suggests that none of us can walk in a (51)______ straight line. Rather, we meander(漫步), mainly due to a slight structural or functional (52)______ of our legs. So steps by the left and right legs of a person are (53)______.
As a result, although we may start walking in a straight line, several steps afterwards we have changed direction. However, (54)______ 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, (55)______ to say, walk straight. It’s all because your ears are still spinning and can’t help you keep your balance. Your inner ear is a structure containing liquids. When you spin, the liquid inside follows your spinning, but when stop, the liquid continues to spin for a while, the result of which is (56)______. For the moment, although your eyesight tells you to walk in a straight line your brain listens to your spinning ears, thus you don’t walk as what your eyes tell.
