Give brief answers to the following questions, using your own words as 1 much as possible: 1 Key to Exercises I. 1)It looks like a stylized Navaho rug or the aerial view of a railroad switching yard. It is made mostly of silicon. 2) The computer of 25 years ago was as large as a room. The miracle chip of today is small, cheap, easy to mass produce, fast, infinitely versatile and convenient. 3) At 7:30 a.m., when the alarm clock burrs, the bedroom curtains swing silently apart, the venetian blinds snap up and the thermostat boosts the heat to a cozy 70'. The percolator in the kitchen starts burbling; the back door opens to let out the dog. The TV set blinks on with the day's first newscast. After the news on TV comes the morning mail, from correspondents who have dictated their messages into the computer network. Mr. A., still in bed, then presses a button on a bedside box and issues a string of business and personal, memos, which appear instantly on the genie screen. After his shower, which has turned itself on at exactly the right temperature at the right minute, Mr. A. is alerted by a buzzer and a blue light on the screen. His boss is on his way to the office. Mr. A. dresses and goes out to the car, the engine of which is running'" After her husband has kissed her goodbye, Mrs. A. uses the computer to do shopping for tonight’s dinner party. Then she orders from the memory bank her favorite recipes, tells the machine to compute the ingredients for six servings, and directs the ovens to reach the correct temperature for each dish according to the recipe, starting at 7:15 p.m. She then joins a televised discussion of art. Later she wanders into the computer room where she has just learned from his headset that his drill in Latin verb conjugation was very good. 4) Home information management systems will take over me-mo pads, notebooks, files, bills and the kitchen bulletin board. And housewives will be able to do their shopping by computer TV. 5) Hospital computers will take the place of doctors to talk to patients and they are programmed not only to remind the pharmacy department to prepare prescriptions but also to alert nurses to give the proper dosage at the right time. 6) In addition to the microprocessors under the hood that will help the machine operate more efficiently, tiny computers will ease tensions and make life simpler for the driver and passengers too. For example, at the push of a button, the driver can get a readout on the amount of fuel in the tank, and the number of miles he can expect to go before a refill is necessary; or he can find out the miles yet to go to a preset destination and the estimated arrival time. The best auto will contain a small portable phone capable of reaching any number in the world in seconds, automatic braking and a miniradar to avoid collisions. 7) In schools, computers will be more common than slide projectors, movie film projectors and tape recorders. They' 11 be used from the moment school opens, through break, through 1) What does a miracle chip look like? What is it made of? 2) What was the computer of 25 years ago like?

Paraphrase: 1) The microelectronic revolution promises to ease, enhance and simplify life in ways undreamed of even by the utopians. 2) The custom-made object, now restricted to the rich, will be within everyone' s reach. 3) The computer might appear to be a dehumanizing factor, but the opposite is in fact true. 4) In no area of American life is personal service so precious as in medical care. 5) The widest benefits of the electronic revolution will accrue to the young. 6) For the mighty army of consumers, the ultimate applications of the computer revolution are still around the bend of a silicon circuit. lunch period, and to the dosing of the school. 8) The computer revolution is stimulating intellects, liberating limbs and pushing mankind to a higher level of existence. 2 II. 1) The breakthrough in microelectronics will change people's lives in ways no one has ever thought of before. 2) Although at present only the rich man can afford custom-made goods, the average person will be able to afford them in the future. 3) The computer might appear to make human beings machinelike, but it can bring some human qualities into our lives as well. 4) Personal service in medical care is regarded as the most important part of the American life. 5) It is the young Americans who will gain most of the advantages from the electronic revolution. 6)Right now, millions of American computer users are not able to make full use of the computer. 3 III. Translate the following into Chinese: 1) Just as the Industrial Revolution took over an immense range of tasks from men's muscles and enormously expanded productivity, so the microcomputer is rapidly assuming huge burdens of drudgery from the human brain and thereby expanding the mind's capacities in ways that man has only begun to grasp. 2) Such painless, productive awakenings will in time be a familiar thing. And, barring headaches, tummy aches and heartaches, the American day should proceed as smoothly as it begins. 3) Public education, so often a dreary and capricious process in the U. S. , may be invested with the inspiriting quality of an Oxford tutorial--from preschool on. 4) Certainly the miracle chip will affect American life in ways both benign and productive. The computer revolution is stimulating intellects, liberating limbs and propelling mankind to a higher order of existence. IV.

Translate the following passage into Chinese: The electronic computers contain five basic sections: Input. This section translates information from a variety of devices into a code that the computer understands. In early computers, the use of punched cards provided the input. Today such cards, as well as punched tape, are still used. But they have been supplemented by other methods, including magnetic tapes, discs and drums. Memory. It stores information until it is needed by other parts of the machine. The most popular memory in modern computers has been the magnetic core variety. The core memories are now being replaced by semiconductor memories on chips. Arithmetic and logic. To handle, direct and process the flood of information, the 10 XI. 电子计算机包括以下五个基本部分： 输入端：这部分将从各种装置获得的信息译成计算机懂得的电码。最初的计算机采用穿 孔卡片送入输入端。现在，这样的卡片以及穿孔带仍在使用，但增补了其他方法，其中包括 磁带、磁盘和磁鼓。 存储器；信息就贮存在这部分里以供计算机其他部分需要时使用。现代化计算机最常见 的存储器是各种磁芯制成的。这种磁芯存储器正在被微型集成电路块上的半导体存储器所取 代。 运算和逻辑部分：计算机依靠这部分来处理、指导、加工大量的信息。计算机在这里对 数字和数据进行运算和操纵。 控制器：这是计算机的交通警，它使指令贮存在存储器中并对指令进行解释。它调节存 储器、运算和逻辑部分以及这些部分之间信息的流动。它还命令经过加工的数据从存储器移 动到输出端。 输出端：这部分把经过加工的数据译成可以控制各式各样装置的电冲。这样，输出端可 以采用文字或数字两种读出形式，显示在高速打字机上或明亮的阴极射线管上。 computer relies on this unit. It is here that the computer does its number crunching and data manipulation. Control. This is the computer's traffic cop. It gets instructions stored in the memory section and interprets them; it regulates the memory and arithmetic-logic sections and the flow of information between them, and orders processed data to move from the memory to the output section. Output. Processed data are translated by this section into electrical impulses that can control an almost endless variety of devices. Thus the output may take the form of words or numbers "read-out" on high-speed printers or glowing cathode-ray tubes. XII. Topics for oral work: 1) Is the computer a humanizing or dehumanizing factor? 2) The author tries to make his science writing interesting and popular. What are some of the methods he employs to achieve this? 11 XIII. Write a short composition on the following topic: The role the computers will play in our four modernizations. 11 XIII. The Role the Computers Will Play in Our Four Modernizations When the computers are 'widely used, we may have large numbers of computerized robots which make our lives easier. Some of them, like the pocket calculator, can work much more quickly than human beings can. And they rarely make mistakes. In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. At first, their electronic brains must be shown how the job is done. A person moves the robot' s "arms" and "hands" through each part of the job. The robot's brain remembers each move. When the robot is put to work on its own, its brain controls the rods, wheels and motors which move its arm. When the robot is needed for a new job, its electronic memory is "wiped clean". Then it is taught how to do its new task. Robots are also used for doing jobs which are dangerous. They can move objects which are too hot or too heavy for people to handle. They can work in places which are too hot or too cold for people. And they are not affected by poisonous fumes or gases. In scientific research, they may be used for doing such jobs as handling radioactive materials. In short, the computers will play an important role in our four modernizations. With their help, we will be relieved of tedious, hard or dangerous work and have more time for more challenging and valuable things or e/ten for entertainment.
