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 abo

Ask an American schoolchild what he or she is learning in school these days and you might even get a reply, provided you ask it in Spanish. But don't bother, here's the answer: Americans nowadays are not learning any of the things that we learned in our day, like reading and writing. Apparently these are considered fusty old subjects, invented by white males to oppress women and minorities.

What are they learning? In a Vermont college town I found the answer sitting in a toy store book rack, next to typical kids' books like Heather Has Two Mommies and Daddy Is Dysfunctional. It's a teacher's guide called Happy To Be Me, subtitled Building Self Esteem.

Self-esteem, as it turns out, is a big subject in American classrooms. Many American schools see building it as important as teaching reading and writing. They call it "whole language" teaching, borrowing terminology from the granola people to compete in the education marketplace.

No one ever spent a moment building my self-esteem when I was in school. In fact, from the day I first stepped inside a classroom my self-esteem was one big demolition site. All that mattered was "the subject", be it geography, history, or mathematics. I was praised when I remembered that "near", "fit", "friendly", "pleasing", "like" and their opposites took the dative case in Latin. I was reviled when I forgot what a cosine was good for. Generally I lived my school years beneath a torrent of castigation so consistent I eventually ceased to hear it, as people who live near the sea eventually stop hearing the waves.

Schools have changed. Reviling is out, for one thing. More important, subjects have changed. Whereas I learned English, modern kids learn something called "language skills." Whereas I learned writing, modern kids learn something called "communication". Communication, the book tells us, is seven per cent words, 23 per cent facial expression, 20 per cent tone of voice, and 50 per cent body language. So this column, with its carefully chosen words, would earn me at most a grade of seven per cent. That is, if the school even gave out something as oppressive and demanding as grades.

The result is that, in place of English classes, American children are getting a course in How to Win Friends and Influence People. Consider the new attitude toward journal writing: I remember one high school English class when we were required to keep a journal. The idea was to emulate those great writers who confided in diaries, searching their souls and honing their critical thinking on paper.

"Happy To Be Me" states that journals are a great way for students to get in touch with their feelings. Tell students they can write one sentence or a whole page. Reassure them that no one, not even you, will read what they write. After the unit, hopefully all students will be feeling good about themselves and will want to share some of their entries with the class.

There was a time when no self-respecting book for English teachers would use "great" or "hopefully" that way. Moreover, back then the purpose of English courses (an antique term for "Unit") was not to help students "feel good about themselves." Which is good, because all that reviling didn't make me feel particularly good about anything.

Which of the following is the author implying in paragraph 5?

A．Self-criticism has gone too far.

B．Communication is a more comprehensive category than language skills.

C．Evaluating criteria are inappropriate nowadays.

D．This column does not meet the demanding evaluation criteria of today.

Which of the following does not contain a non-finite clause?

A．He swims in the river every day.

B．Do you mind my shutting the door?

C．It's been nice talking to you.

D．There being nothing to do, he left.
