　　No one knows how man learned to make words. Perhaps he began by making sounds like

　　those made by animals. Perhaps he granted like a pig when he lifted something heavy. Perhaps he made sounds like those he heard all round him water splashing, bees humming, a stone falling to the ground. Somehow he learned to make words. As the centuries went by, he made more and more new words. This is what we mean by language.

　　People living in different countries made different kinds of words. Today there are about fif-teen hundred different languages in the world. Each contains many thousands of words. A very large English dictionary, for example, contains four or five hundred thousand words. But we do not need all these. Only a few thousand words are used in everyday life.

　　The words you know are called your vocabulary. You should try to make your vocabulary big-ger. Read as many books as you can. There are plenty of books written in easy English for you toread. You will enjoy them. When you meet a new word, find it in your dictionary. Your dictiona-ry is your most useful book.

　　"High tech" and "state of the art" are two expressions that describe the modem technology.

　　High tech is just a shorter way of saying high technology. And high technology describes any in-vention, system of device that uses the newest ideas or discoveries of science and engineering.

　　What is high tech? A computer is high tech. So is a communications satellite. A modem manufac-turing (生产) system is surely high tech. High tech became a popular expression in the United States during the early 1955' s. Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave ovens, etc.

　　"State of the art" is something that is as modem as possible. It is a product that is based on the very latest methods and technology. Something that is "state of the art" is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modem electronic design and parts. It is the best that one can buy.

　　"Stare- of the art" is not a new expression. Engineers have used it for years, to describe the best and most modem way of doing something. Millions of Americans began to use the expression in the late 1970' s. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art".

　　Computer technology changed so fast that a state of the art computer today might be old to-morrow. The expression "state of the art" became as common and popular as computers them-selves. Now all kinds of products are said to be "state of the art".
