How men first learned to invent words is unknown; in other words, the origin of language i

s a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to ex press thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words.

There power of words, then, lies in their associations the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions.

The origin of language is ______.

A．a legend handed down from the past

B．a matter that is hidden or secret

C．a question difficult to answer

D．a problem not yet solved

听力原文： Villages in developing countries often lack many things. Books, clean water, electricity. These shortages are easy to see. But a different kind of shortage is not easy to see. That is a shortage of experts. Many villages have no doctors, engineers or scientists. They have no one who knows how to treat unusual medical problems or design a new energy system. Them' s a way to ease these problems. They can de it with computers. In the past few years, computer scientists around the world have developed what they call expert systems. An expert system is a special kind of computer program. In some situations, it can take the place of a human expert. For example, an expert in medical system can help care for a sick person. A question appears on the computer screen, "Is the person hot？" You tell the computer either yes or no. The computer asks other questions. "Has the person lest any blood？" "Can the person move normally？" You answer. The computer continues to ask questions until it has enough information to make a decision. Then it tells what medicine or other treatment is needed. In this way the ex pert system takes the place of a doctor. Another kind of expert system takes the place of an engineer. It measures the flow of water in a river. It tells if a dam can be built on the river. It also tells how much electricity can be produced. Still other kinds of expert systems help solve problems for farmers and owners of small businesses.
