Passage 20 How men first learned to invent words is unknown; in other words, the origin of language is a mystery. (20) All we really know is that men, unlike animals, somehow invented certain sounds to express 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. The power of words, then, lies in their combinations--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 feelings. This charming and telling use of words is what we call literary (文字的) style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and rude. According to the passage, words are______.

Passage 38 Animals do many useful and entertaining jobs. (38) Dogs are particularly valuable in guiding the blind (a trained dog can learn never to cross a busy street when cars are coming, even if his master commands him to do so), protecting property, finding lost people, and hunting criminals. Horses are used in guarding herds, carrying men in lands where there are no roads, and helping farmers plow fields. Pigeons have long been used to carry message. Wild animals from the jungles, forests and seas are very popular performers in circuses and movies. People realize that, although animals may not have the same intelligence as human beings, they are smart enough to learn certain things. The first thing a dog is taught is to obey. It should not take too long for him to learn commands. Simple orders, such as "sit, lie down, stay there, come here" can even be taught by a child. Training a dog to be a watchdog often produces unexpected results. Some dogs quickly learn the difference between unwanted people and friends. This is because their masters welcome friends and invite them into their houses. However, some dogs will always attack the postmen who come to deliver letters. One explanation for this behavior is that, although the postman comes to the house frequently, he never enters the house. Therefore, the dog thinks the postman is someone who is not wanted, but keeps coming back anyway. Masters of dogs who attack postmen can easily show the dogs that the postman is a friend and the dog does not need to treat him as an unwanted person. A dog is quite ready to do what his master wishes. And a dog is always happy when he is praised for proper understanding. Some dogs always attack the postman because______.
Passage 11 Obviously television has both advantages and disadvantages. In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don’t have to pay for expensive seats at the theatre, the cinema, or the opera. All they have to do is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if he has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort on his part. Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. (11) It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it, so dependent on its pictures that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and that they have actually begun to talk to each other again. It makes one think, doesn’t it There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society. According to the passage, whether TV is good or not depends on______.
Passage 17 "High tech" and "state of the art" are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device that uses the newest ideas or discoveries of sci-ence and engineering. What is high tech A computer is high tech. So is a communications satellite. A modern manufacturing (生产) system is surely high tech. High tech became a popular expression in the United States during the early 1980’s. (17) Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave (微波) ovens, etc. "State of the art" is something that is as modern 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 modern electronic design and parts. It is the best that one can buy. "State of the art" is not a new expression. Engineers have used it for years, to describe the best and most modern 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 tomorrow. The expression "state of the art" became common and popular as computers themselves. Now all kinds of products are said to be "state of the art". Which of the following statements is NOT true
