单选题One of the most eminent of psychologists, Clark Hull, claimed that the essence of reasoning lies in the putting together of two 'behavior segments' in some novel way, never actually performed before, so as to reach a goal. Two followers of Clark Hull, Howard and Tracey Kendler, (21) a test for children that was explicitly based on Clark Hull's principles. The children were given the (22) of learning to operate a machine so as to get a toy. In order to succeed they had to go through a two-stage (23) . The children were trained on each stage (24) . The stages consisted merely of pressing the correct one of two buttons to get a marble; and of (25) the marble into a small hole to release the toy. The Kendlers found that the children could learn the separate bits readily enough. (26) the task of getting a marble by pressing the button they could get the marble; given the task of getting a toy when a marble was handed to them, they could use the marble. (All they had to do was put it in a hole.) (27) they did not for the most part 'integrate', to use the Kendlers' terminology. They did not press the button to get the marble and then (28) without further help to use the marble to get the toy. So the Kendlers concluded that they were incapable of deductive (29) . The mystery at first appears to deepen when we learn, from (30) psychologist, Michael Cole, and his colleagues, that adults in an African culture apparently cannot do the Kendlers' task either. But it lessens, (31) when we learn that a task was devised which was (32) to the Kendlers' one but much easier for the African males to handle. (33) the button-pressing machine, Cole used a locked box and two (34) colored match-boxes, one of which contained a key that would open the box. Notice that there are still two (35) segments--"open the right matchbox to get the key" and "use the key to open the box"--so the task seems formally to be (36) But psychologically it is quite different. Now the subject is dealing not with a strange machine but with familiar meaningful objects; and it is clear to him what he is meant to do. It then (37) that the difficulty of integration is greatly reduced. Recent work by Simon Hewson is of great interest here for it shows that, for young children, (38) , the difficulty lies not in the (39) processes which the task demands, but in certain perplexing features of the apparatus and the procedure. When these are changed in ways which do not at all affect the inferential nature of the problem, then five-year-old children solve the problem (40) college students did in the Kendlers' own experiments.

单选题It appears that the telephone is the principal organization element in the ordering of an information society. But whether a telephone takeover is within the realm of possibility or beyond it, today"s ordinary telephone is capable of performing electronic tricks that just a few years ago seemed possible only in the realm of science fiction. Your telephone already can tell you, while you are speaking to one person over the telephone, that someone else is trying to reach you. The "call waiting" service emits a soft sound which only you can hear, letting you know that someone else is trying to get through. You can hold the first call and answer the second, and if necessary, switch back and forth between the two calls. "Call forwarding" makes it possible for all of your incoming calls to be transferred to another number, either at a place at which you plan to be, or where someone can take messages. "Three-way Calling", as the name suggests, allows for a three-way conversation. The future opens up even more interesting prospects of new telephone services. You could arrange to have incoming calls from preselected numbers identified by different ringing patterns so that, without picking up the telephone, you could tell who was calling. Instead of repeatedly dialing someone, you could tell your telephone to keep dialing the number, when it is free, it will let you know. Now, all current predictions about the use of home computers for shopping, education and information gathering involve a connection with the telephone system.

单选题About one million tourists go to Barcelona every year, just to visit the Gaudi's Church. This unusual church has a strange history. Gaudi was born in Spain in 1852. He had to work and study at the same time. He often missed classes because he had to work, but one day he designed a very unusual showcase for an exhibition in Paris. People began to give him work. He designed houses, offices and gardens. They were all very unusual. He was soon rich and famous. Then a rich bookseller said, "Will you build a church for the poor people of Barcelona? I will pay. I will build schools and workshops, too. They will help the people." "I will do it," said Guadi. He worked for forty years, but he could not finish the church. It was too big. He needed $10, 000, 000. He gave all his money to the church. He was poor again when he died in 1926, and only the front part of the church was finished. Now, architects, engineers and tourists from all over the world like to come and see the church, which is very strange, very modem and very revolutionary.

单选题{{B}}Passage Three{{/B}} It is hard to imagine a more perfect gift than a fine watch, which lasts a lifetime and can become a family heirloom (传家宝). "Other gifts that you give don't last very long," says vice president Karl-Friedrich Scheufele of Geneva-based Chopard. "And there are very few that stay with the person wherever they go. This is the amazing thing about watches -- they are both beautiful and intimate. You have one on your wrist, and you remember a happy time in your life when you look at it." For something so personal, choosing the right watch demands corresponding care. Here is a brief look at some trends watch buyers will encounter this season. The most obvious trend in watches this season is the overwhelming popularity of sports watches in stainless steel. Yellow gold and two-tone watches of gold and steel are out -- and full steel is in. With the steel trend comes sportiness (花哨), which has been the industry's watchword, as it were, for the past three years. Generally speaking, the demand for large-scale steel-case designs -- with either steel or leather straps -- has led to a great supply of large, even bulky, designs for both men and women. "There is a demand for watches that are bigger and bolder," says Suryia Hill, media-relations manager for Roberg6 Watches Geneva. At Citizen, bulky sports watches are the big sellers. "People like to differentiate themselves with their watches, and calm, thin designs are not popular at the moment," says Willi Richter, general manager of Hamburg-based Citizen Watch Europe GmbH. "Young, middle-aged and even older people these days want to show that they are active, so they prefer bold, active watches."

单选题 A mother dolphin (海豚) chats with her baby over the telephone! They were in separate tanks connected by a special underwater audio link. "It seemed clear that they knew who they were talking with," says Don White, whose Project Delphis ran the experiment. But what were they saying? Scientists think dolphins "talk" about everything from basic facts like their age to their emotional state. "I speculate that they say things like 'there are some good fish over here,' or 'watch out for that shark because he's hunting,'" says Denis Herzing, who studies dolphins in the Bahamas. Deciphering (译解) "dolphin speak" is also tricky because their language is so dependent on what they're doing, whether they're playing, fighting, or going after tasty fish. During fights, for example, dolphins clap (碰撞) their jaws to say "Back off!" But their jaws clap while playing, too, as if to show who's king of the underwater playground.

单选题In order to learn a foreign language well, it is necessary to overcome the fear of making mistakes. If the primary goal of language use is communication, then mistakes are secondary considerations that may be dealt with gradually as awareness of those mistakes increases. On the other hand, students should not ignore their mistakes. The language learner may observe how native speakers express themselves, and how native expressions differ from the way the learner might say them. For example, a Spanish speaker who has been saying "I do it. " to express willingness to do something in the immediate future, could, by communicating with native speakers of English, observe that native speakers actually say "I'll do it. " This difference can serve as a basis for the student to change his way of using the present tense in English. But a student who is unwilling to communicate in the first place would lose this opportunity to learn by trial and error.
