英语专八精读练习：holmes’knowledge

his ignorance was as remarkable as his knowledge. of contemporary literature, philosophy and politics he appeared to know next to nothing. upon my quoting thomas carlyle, he inquired in the naivest way who he might be what he had done. my surprise reached a climax, however, when i found incidentally that he ignorant of the copernican theory and of the composition of the solar system.

"you appear to be astonished,”holmes said, smiling at my expression. "now that i do know it i shall do my best to forget it. you see, i consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: a fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. it is a mistake to think that the little room has elastic walls and can distend to any extent. depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. it is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”

"but the solar system!”i protested.

"what the deuce is it to me?" he interrupted impatiently.

one morning, i picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. one of the articles had a pencil mark at the heading, and i naturally began to run my eye through it.

its somewhat ambitious title was "the book of life,”and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. it struck me as being a remarkable mixture of shrewdness and of absurdity. the reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. the writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man\' s inmost thought.

deceit, according to him, was impossibility in the case of one trained to observation and analysis. his conclusions were as infallible as so many propositions of euclid. so startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.

"from a drop of water,”said the writer, "a logician could infer the possibility of an atlantic. so all life is a great chain, the nature of which is known whenever we are shown a single link of it. like all other arts, the science of deduction and analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it.”

this smartly written piece of theory i could not accept until a succession of evidences justified it.

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
