Most people talk about the "five" senses of man. And it is true that we get our informatio
n about the outside world from our senses of sight, hearing, smell, touch and taste. Researchers tell us that sense of sight -- our visual (视觉的) sense -- gives us up to eighty percent 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 20% of what is happening. But there are two other senses that we cannot get along without it, though they are seldom noticed. These are the sense of balance, without which we would act like a drank man, and the kinetic(运动的) sense, which gives us our ideas about our own motion(行动).

The senses of hearing, smell, touch and taste supply us with _________.

A.about 80% of our information about the world

B.about half of our information about the world

C.about 20% of our information about the world

D.all the needed information about the world

听力原文: People enjoy taking trips. But what are the reasons they leave home? One reason is for education. People travel because they want to broaden their horizons, to learn about other people and other places. They're curious about other cultures. When people are tourists, they get a quick look at different ways of living. Even a short look at another kind of lifestyle. is an important lesson.

On a trip, a person can learn directly by visiting museums and historic spots. What does a tourist learn who sees the art museums, visits the historic palaces and other scenic spots in Paris shops along the river Seine? He gets a vivid picture, a real life one of the French people. He learns about their attitudes, how they feel about business, beauty and history.

What about the tourist who goes to Hong Kong? Does he get the same information that he could get from a book? He might read that Hong Kong is crowded, that there's less than 200 square meters of space for each person, but seeing and feeling the lack of space will impress him much more. He might read that there've nearly 200 vehicles for every kilometer of roadway, but the sight of so many vehicles parked along the roadside will be a much more vivid lesson. The tourist to Hong Kong will never forget the contrasts. the straight vertical lines of the tall modern buildings and the moving lines of boats that people live in.

A.To look for a different lifestyle.
