参考答案C
解析: Everyone talks about the five senses of man.(20) 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 sense, gives us up to 80 percent of what we know about the world outside our bodies. While the other senses, the hearing, the smell, the touch and the taste bring into our brains information about the other 20 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 motor sense.(21) The sense of balance, without which we would act like a drunk,is located in the inner ear.The inner ear contains three curved tubes, filled with liquids.The shifting of these liquids activates nerve endings in the linings of the canals.And nerve impulses from these nerve endings help our brains to keep us up right.The motor sense is actually made up of nerve impulses that arise from nerves planted in close contact with our muscles.(22) These nerve messages are constantly telling us what position our limbs, trunk and head are in.They serve as a continuous feedback system to help us know how to move our various parts and when to hold them still.Otherwise we would lack the coordination to run, jump, dance the twist, or even sit still.Incidentally the word motor comes from two Greek words meaning motion and feeling.The motor sense gives our ideas about our own motion.

C.【精解】文章开头提到，我们通过视觉、听觉、嗅觉、触觉和味觉来获取外部世界的信息。因此，答案为C.
