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.

SECTION A MINI-LECTUREDirections: In this section you sill hear a mini-lecture. You will hear the lecture ONCE ONLY. While listening, take notes on the important points. Your notes will not be marked, but you will need them to complete a gap-filling task after the mini-lecture. When the lecture is over, you will be given two minutes to check your notes, and another ten minutes to complete the gap-filling task on ANSWER SHEET ONE. Use the blank sheet for note-taking.听力原文： Good morning, everyone. First about your second assignment. I'd like to remind you that your second assignment should be in by next Fri day. You can either put it in my pigeon hole, or leave it with the Department's secretary. Now, let's get down to the lecture.Today, the lecture is on credit, er, or to be more specific, on credit cards. I'm sure you must have heard of some credit cards, like the VI SA card, which is an internationally used card, or the Great Wall card issued by the Bank of China, In order to give a better understanding, we'll discuss it in some detail.Many businesses, such as department stores, restaurants, hotels and airline companies, use a credit system for selling their products and services. In a credit system, the seller agrees to sell something to the buyer without immediately receiving cash. He receives the goods or ser vices immediately and promises to pay for them later. This buy-now-pay later credit system is quite old.There are two types of credit cards. One type is issued directly by a store to a customer. Many large department stores issue credit cards to their customers. The store credit card can be used to make purchases only at a particular store. For example, if you have a credit card from Store A, then you can only buy things in that store. Other stores would not accept it. The other kind of credit card is issued by a credit company. Credit cards from credit companies can be used to buy things almost anywhere. If you have a major credit card, you can buy airplane tickets, stay at hotels and eat at restaurant with it. Most large credit companies are connected to large banks. So if you want a credit card from a credit company, you generally have to make an application at a bank. After an applicant receives a credit card, he or she can make purchases using thecard.The credit company sends the customer a statement of purchases at the end of each month. Generally the customer has to pay 25--50% of their credit hill every month. The customer pays directly to the credit company and the credit company pays to the store or hotel or restaurant.There are some advantages and some disadvantages to using credit cards. The biggest advantage for the consumer is expressed by the phrase "buy now, pay later". This means that the consumer can purchase what he wants when he wants it. There is no need to save up money in advance. Another advantage of having a credit card is that it protects the owner, ff a credit card is lost or stolen, the owner only has to call the credit company and the credit company will stop the credit card number. No one else can use it. So the owner doesn't have to worry about losing the card. Another advantage of the credit card system is that the consumer receives a record of his or her purchases. Every month the credit customer receives a bill. The bill has a list of all purchases from that month. This makes it easier to remember when and where purchases are made. And another advantage is that credit cards can be used when something unexpected happens. Many kinds of professional people—plumbers, taxidrivers, doctors and dentists—will accept credit cards in an emergency. This is very important if you don't have any cash with you.However, having said all that, using credit cards has one major disadvantage. That is, consumers tend to overspend their money. They spend more than they make. If a consumer buys a lot of th

SECTION A CHINESE TO ENGLISHDirections: Translate the following text into English.窗子许里面人看出去，同时也许外面人看进来，所以在热闹地方住的人要用窗帘儿，替他们的私生活做个保障。晚上访人，只要看窗里有无灯光，就约略可以猜到主人在不在家，不必打开了门再问，好比不等人开口，从眼睛里看出他的心思。关窗的作用等于闭眼。天地间有许多景象是要闭了眼才看得见的，比如梦。假使窗外的人声物态太嘈杂了，关了窗好让灵魂自由地去探胜，安静地默想。
