Everyone talks about the "five" senses of man. And it’s true that we get our information about the outside world from our sense of sight, hearing, smell, touch and taste. Researchers tell us that the sense of sight--our visual--gives us up to 80% of what we know about the world outside our bodies while the other senses, the auditory (hearing), the olfactory (smell), the tactile (touch), and the gustatory(taste) bring into our brains information about the other twenty percent of what is happening. But there are two other senses that we cannot get along without, though they are very seldom given any credit for helping us to survive in this difficult world. These are the sense of balance, and the kinesthetic sense. The sense of balance, without which we would act like a drunk after a heavy bout with the bottle, is located in the inner ear. The inner ear contains three curved tubes (the semi-circular canals) tilted with liquids. The shifting of these liquids activates nerve endings in the linings of the canals and nerve impulses from these nerve endings help oar brains to keep us upright. The kinesthetic sense is actually made up of nerve impulses that arise from nerves planted in close contact with our muscles. These nerve messages are constantly telling us what position our limbs, trunk and head are in. They serve as a continuous "feed-back" system to help us know how to move our various parts, and when to held them still. Otherwise, we would lack the coordination to run, jump, dance the twist, or even sit still. Incidentally, the word "kinesthetic" comes from two Greek words meaning "motion" end "feeling." The kinesthetic sense gives us our ideas about our own motion. What is the main idea of the passage
C 根据下面短文回答下列问题。 Long long ago, there was an old farmer who had seven children. When he thought that he was about to die, he let them come to his bed. He told the servant to bring in a bundle (一捆) of seven sticks (棍子) tied together (栓在一起). Giving the bundle to his oldest child, the father said to him, "Now break the bundle." The son tried with all his strength, but he could not break the bundle. One by one, the other children tried. But not one of them was strong enough to break it. The father smiled, "Now my children, untie the bundle. Each of you takes a stick and tries to break it." This time they had no difficulty doing it as their father told them. In a minute, all the sticks were broken. The seven children then understood what their father wanted to tell them. A bundle of sticks was harder to break than a single one.
