There are thousands of different languages in the world. Everyone seems to think that his native language is the most important one, as it is their first language. For many people it is even their only language all their lives. But English is the world's most widely used language.

　　As a native language, English is spoken by nearly three hundred million people, in the U.S.A., England, Australia and some other countries.

　　For people in India and many other countries, English is often necessary for business, education and other activities. So English is the second language there.

　　As a foreign language, no other language is more widely studied or used than English. We used it to listen to the radio, to read books or to travel. It is also one of the working languages in the United Nations and is more used than the others.

　　Questions 26~30

　　What is your favorite colour? Do you like yellow, orange, red? If you do, you must be a person full of hopeful happy feeling about life. Do you like grey and blue? Then maybe you are quiet, and you would rather go after than go before. And sometimes you feel unhappy. If you love green, you are strong-minded. You wish to do everything well and want other people to see you are successful. At least this is what psychologists tell us. They tell us that we don't choose our favourite colour as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

　　A yellow room makes us feel happier and more comfortable than a dark green one; and a red dress brings warmth and gladness to the saddest winter day. Light and bright colours make people not only happier but more active. It is a fact that factory workers work better, harder and have few accidents when their machines are painted orange rather than black dark grey.

　　Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colourful things. Remember also that you will know your friends better when you find out what colours they like and dislike. And don't forget that anyone can guess a lot about your character when you choose something in different colours.
