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.
According to the passage, ______ has become the driving force for the development of telephone system?A．information technologiesB．InternetC．PCD．convergence of telecommunications technologies

短文理解听力原文： The banking system of China evolved from a mono-banking system between the 1940s and the early 1970s. Not until 1978 did China's banking system make a drastic shift in its banking philosophy and structure. The shift is not only a necessity for the country's development, but also acts as a gesture showing the "openness" of the country to the outside world.Today, after nearly forty years of rapid development, China is moving towards a modem and market-oriented banking structure although there is still much to be improved to meet the needs of the country's development.In the mid 1990s, banks in China began to focus their attention on capital adequacy requirements, non-performing and bad loans, profitability and also the industry's overall expansion strategy. Reforms of monetary and financial system in China are speeding up in the 90s. Existing specialized banks gradually have become commercial banks.21. What kind of banking system did China have before the 1980s?22.Up to now, how long has China experienced rapid development?23.What are the banks in China focusing their attention on?(21)A．The same system as in the western countries.B．A mono-banking system.C．A modern banking system.D．A commercial banking system.
