 The goal of Internet-based encyclopedia Wikipedia (www.wikipedia.org) is to give everyone on 
the planet access to information. Like other encyclopedias, Wikipedia contains lots of information: 
more than 2.5 million articles in 200 different languages covering just about every subject. Unlike 
other encyclopedias, however, Wikipedia is not written by experts, but by ordinary people. These 
writers are not paid and their names are not published. They contribute to Wikipedia simply because 
they want to share their knowledge. 
 Encyclopedias began in ancient times as collections of writings about all aspects of human 
knowledge. The word itself comes from ancient Greek, and means “a complete general education”. 
Real popularity for encyclopedias came in the nineteenth century in Europe and the United States, 
with the publication of encyclopedias written for ordinary readers. With the invention of the CD-
ROM, the same amount of information could be put on a few computer discs. Then with the Internet, 
it became possible to create an online encyclopedia that could be constantly updated, like Microsoft’s 
Encarta. However, even Internet-based encyclopedias like Encarta were written by paid experts. At 
first, Wikipedia, the brainchild of Jimmy Wales, a businessman in Chicago, was not so different from 
these. In 2001, he had the idea for an Internet-based encyclopedia that would provide information 
quickly and easily to everyone. Furthermore, that information would be available free, unlike other 
Internet encyclopedias at that time. 
 But Wales, like everyone else, believed that people with special knowledge were needed to write 
the articles, and so he began by hiring experts. He soon changed his approach, however, as it took 
them a long time to finish their work. He decided to open up the encyclopedia in a radical new way, so 
that everyone would have access not only to the information, but also to the process of putting this 
information online. To do this, he used what is known as “Wiki” software (from the Hawaiian word 
for “fast”), which allows users to create or alter content on web page. The system is very simple: 
When you open the web site, you can simply search for information or you can log on to become a 
writer or editor of articles. If you find an article that interests you – about your hometown, for example 
– you can correct it or expand it. This process goes on until no one is interested in making any more 
changes.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the 
correct answer to each of the questions from 61 to 70 
Fiberscopes are one of the most are one of the most important outcomes of he science of fiber 
optics. Fibers made of glass and transparent acrylic plastic are capable of conveying light energy, and 
when thousands of these fibers are combined in what is called a fiberscope, they can transmit images. 
The most common fiberscopes contain about 750,000 fibers, each 0.001 centimeter, or 10 microns, in 
diameter. For certain uses, the diameter of the fiber may be as small as 5 microns. 
Fiberscopes have a wide range of applications. In the medical field, physicians use fiberscopes 
to examine internal organs and as an aid in delicate surgeries. Miniature probes have also been 
developed to view muscle fiber, skin tissue, and blood cells. Fiberscopes have also found varied uses 
in industry, particularly to inspect or control operations in inaccessible areas. Bundles of fiberscopes 
fused together in a solid plate, called a faceplate, are being used in the manufacture of television tubes 
and other cathode-ray tube devices. 
The most far reaching applications of fiber-optic technology are in communication. Optical 
fibers carry voice messages for telephone service. The sound of the voice is electronically broken 
down into thousands of pulses per second, which causes a transmitting laser to send coordinated 
pulses of light through the optical fibers. At the receiving end, the light pulses are converted to 
electrical signals and the voice message is reconstructed. Light-wave communication systems can 
handle an immensely greater number of telephone calls and television programs than the current 
system, and they will form the basis of the “electronic superhighway” expected to crisscross the nation 
in the near future of the information age. 
Question 61: How do optical fibers carry voice message?
