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.
