Across a wide variety of fields, data are being collected and accumulated at a dramatic pace. There is an urgent need for a new generation of computational theories and tools to assist humans in(96)useful information(knowledge) from the rapidly growing(97)of digital data. These theories and tools are the subject of the emerging field of knowledge discovery in database(KDD). At an abstract level, the KDD field is concerned with the development of methods and techniques for making(98)of data. The basic problem addressed by the KDD process is one of mapping low-level data(which are typically too voluminous to understand and digest easily) into other forms that might be more(99)(for example, a short report), more(100)(for example, a descriptive approximation or model of the process that generated the data), or more useful(for example, a predictive model for estimating the value of future cases). At the core of the process is the application of specific data-mining methods for pattern discovery and extraction.

4.Telecommunications stand for devices and systems that transmit electronic or optical signals across long distances. Telecommunications enables people around the world to contact one another, to access information instantly, and to communicate from remote areas. Telecommunications usually involves a sender of information and one or more recipients linked by a technology, such as a telephone system, that transmits information from one place to another. Telecommunications enables people to sand and receive personal messages across town, between countries, and to and from outer space. It also provides the key medium for delivering news, data, information, and entertainment.Telecommunications devices convert different types of information, such as sound and video, into electronic or optical signals. Electronic signals typically travel along a medium such as copper wire or are carried over the air as radio waves. Optical signals typically travel along a medium such as strands of glass fibers. When a signal reaches its destination, the device on the receiving end converts the signal back into an understandable message, such as sound over a telephone, moving images on a television, or words and pictures on a computer screen.Telecommunications messages can be sent in a variety of ways and by a wide range of devices. The messages can be seat from one sender to a single receiver (point-to-point) or from one sender to many receivers (point-to-multipoint). Personal communications, such as a telephone conversation between two people or a facsimile (fax) message (see Facsimile Transmission), usually involve point-to-point transmission. Point-to-multipoint telecommunications, often called broadcasts, provide the basis for commercial radio and television programming.Telecommunications begin with messages that are converted into electronic or optical signals. Some signals, such as those that carry voice or music, are created in an analog or wave format, but may be converted into a digital or mathematical format for faster and more efficient transmission. The signals are then sent over a medium to a receiver, where they are decoded back into a form. that the person receiving the message can understand. There are a variety of ways to create and decode signals, and many different ways to transmit signals.Individual people, businesses, and governments use many different types of telecommunications systems. Some systems, such as the telephone system, use a network of cables, wires, and switching stations for point-to-point communication. Other systems, such as radio and television, broadcast radio signals over the air that can be received by anyone who has a device to receive them. Some systems make use of several types of media to complete a transmission. For example, a telephone call may travel by means of copper wire, fiber-optic cable, and radio waves as the call is sent from sender to receiver. All telecommunications systems are constantly evolving as telecommunications technology improves. Many recent improvements, for example, offer high-speed broadband connections that are needed to send multimedia information over the Internet.Personal computers have pushed the limits of the telephone system as more and more complex computer messages are being sent over telephone lines, and at rapidly increasing speeds. This need for speed has encouraged the development of digital transmission technology. The growing use of personal computers for telecommunications has increased the need for innovations in fiber-optic technology.Telecommunications and information technologies are merging and converging. This means that many of the devices now associated with only one function may evolve into more versatile equipment. This convergence is already happening in various fields. Some telephones and pagers are able to store not only phone numbers but also names and personal information aboA．Current development.B．Transmission of message.C．Computer networking.D．Government regulation.

    Practice 4　 Read the following text(s) and write an essay to　 1) summarize the main points of the text(s),　 2) make clear your own viewpoint, and　 3) justify your stand.　 In your essay, make full use of the information provided in the text(s). If you use more than three consecutive words from the text(s), use quotation marks (“ ”).　 You should write 160—200 words on the ANSWER SHEET.　 The information and computer technologies have boosted the efficiency and convenience of people’s work and study. Their application in school education has provided teachers and students with new approaches to knowledge and information. There is a heated discussion about whether computers will replace teachers. The following are the supporters’ and opponents’ opinions.　 Supporters:　 With the advanced computer and Internet, children can get the learning material whenever they want.　 Online teaching is becoming more and more popular that students can get planned lessons online. After each class, there is homework for them to do. Both the learning and practice can be done on computers.　 From computers students can learn something that they are interested in so that they won’t be restricted to the subjects that they are taught at school. Therefore, students will have the opportunity to achieve an all-around development.　 Opponents:　 Students need to communicate with teachers and get instructions from them whenever they have troubles in their study. Computers are only cold devices that will affect children’s ability to have face-to-face communication.　 Education is not only about imparting the knowledge, but also being a useful person. So students need to learn some useful values to be a good person which sometimes cannot be easily learned from computers.　 Children who use computer will learn to communicate with machines instead of people. There is a risk that they will be a generation of social illiterates.

    正确答案： 【范文】
    The introduction of computers into classroom has greatly changed the traditional way of teaching and learning. Will computers replace teachers? Some supporters hold the view that computers provide different online teaching and students can get all-round development, while the opponents believe that teachers’ teaching is irreplaceable because it can teach children the values of life. In my opinion, it is impossible for computers to replace teachers.
    I admit that computers benefit students in many ways, they can do their assignments with the help of appropriate software. They also access the Internet for research and entertainment. But as Spencer said, education has for its object the formation of character.” This is also the essence of the quality-oriented education advocated by our government. We need students who can think creatively, not cut and paste their essays out of software encyclopaedia. We need students who can tell truth from lies, not download unedited trivia from the Internet. We need students who can communicate face-to-face with others, not hide behind emails. These are the very aspects where teachers can provide help and guidance.
    So teachers needn’t fear they would be replaced by computers. Instead, they should worry that if they did not adopt new technology, they would become outdated. Faced with the challenge of modern technology, what they should do is to change their attitudes. By learning and using this progressive approach, they can make their teaching more interactive and effective.

    Most current therapies—drugs that were developed during the first golden era, in the 1970s—simply attack dividing cells. That stops tumours, but it also kills all rapidly proliferating cells, regardless of their origin, function or state of health. The action of these drugs on normal tissues causes the side effects, including nausea, fatigue and weakened immune systems, associated with cancer treatment. By contrast, the new generation of drugs, several of which are already in the clinic, attack only deranged cells. These drugs are designed to fix the specific molecular problems in a tumour that drive its growth.
