Question

阅读理解 　　A recent experiment held in Japan shows that it is almost impossible for people to walk exactly straight for 60 metres．Tokyo University of Agriculture and Technology found 20 healthy men and asked them to walk as straight as possible to a target of 60 metres away at a normal speed．Each man had to walk on white paper fixed flat to the floor wearing wet colored socks．The footprints revealed⑧ that all walked in a winding⑨ rather than a straight line．Researchers found that people readjust⑩ the direction of walking every few seconds．The amount of the winding differed from subject to subject．This suggests that none 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(四肢)Although we may start walking in a straight line, several steps afterwards we have changed the direction． 　　Eyesight 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 closing, you can hardly stand still, let alone walk straight． 　　It's all because your ears help you balance．Inside your inner ear there is a structure contains liquids．On the sides of the organ are many tiny hair-like structures that move around as the liquid flows．When you spin(旋转)the liquid inside also spins．The difference is that when you stop, the liquid continues to spin for a while．Dizziness(眩晕)is the result of these nerves in your ears．When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will trust your ears more, thus you walk in a curved line． (1) The experiment held in Japan prove that ________． [　　] A． all the participants(参与者)have a good sense of direction B． none of the participants finished the 60 metres C． the participants keep readjusting their direction of walking D． the experiment was done in different ways (2) What help to readjust our walking direction? [　　] A． Eyes． B． Ears． C． Limbs． D． Footprints． (3) We cannot walk exactly straight because ________． [　　] A． our limbs have some difficulty in keeping balance B． the shape of our body is not well formed C． our left legs and right legs are not the same D． we have no sense of direction while walking (4) The purpose of writing the article is to ________． [　　] A． point out the importance of noticing everyday science B． give background information about a latest study C． prove that ears and eyes help us to walk straight D． explain why we can hardly walk in a strictly straight line
