In what seems like the prehistoric times of computer history; the earth ’ s
postwar era, there was quite a widespread rumor that computers would take over
the world from man one day. Already today, less than fifty years later, as
computers are relieving us of more and more of the routine tasks in business and
in our personal lives, we are faced with a less dramatic but not less foreseen
problem. People tend to be over-trusting of computers and are reluctant to
challenge their authority. Indeed, they behave as if they were hardly aware that
wrong buttons may be pushed, or that a computer may simply malfunction.
Obviously, there would be no point in investing in a computer if you had to
check all its answers, but people should also rely on their own internal
computers and check the machine when they have the feeling that something has
gone wrong. Questioning and routine double-checks must continue to be as much a
part of good business as they were in pre-computer days. Maybe each computer
should come with the warning: for all the help this computer may provide, it
should not be seen as a substitute for fundamental thinking and reasoning
skills.

If you do not find the required information using the tips from the previous
section, then you need to consult an online service to find the piece of
information you were looking for. Three different types of services have been
established over the years: crawlers, directories and meta search engines. The
first crawler was created back in 1993. It was called the World Wide Worm. It
crawled from one site to the next and indexed all pages by saving the content of
the web pages into a huge database. Crawlers or spiders visit a web page, read
it, and then follow links to other pages within the site and even follow links
to other sites. Web crawlers return to each site on a regular basis, such as
every month or two, to look for changes. Everything a crawler finds goes into a
database, which people are able to query. The advantage of the web crawlers is
that they have an extensive database with almost the complete Internet indexed
in it. The disadvantage is that you get thousands of web pages as a response for
almost any request. Web directories work a little differently. First of all they
contain a structured tree of information. All information entered into this tree
is either entered by the webmaster who wants to announce his new web page or by
the directory maintainer who looks at the web pages submitted. The directories
where webmasters can submit both the URL (Uniform Resource Locator) and the
description normally contain more misleading information. Getting into most web
directories is a combination of luck and quality. Although anyone is able to
submit a web page, there is no guarantee that a certain page will be included.
Some directories charge for submission, which is basically a rip-off. Some
crawlers maintain an associated directory. If your site is in the directory, the
ranking of your web site normally will be higher, as it is already
pre-classified. Many directories work with crawlers together, in order to
deliver results, when nothing can be found in the directory. Meta search engines
do not have a database with URLs and descriptions. Instead they have a database
of search engines. If you enter your keywords into a meta search engine it will
send out requests to all the directories and crawlers it has stored in its
database. The meta search engines with a more sophisticated application in the
background are able to detect double URLs which come back from the various
search engines and present only a single URL to the customer.
34. Crawler is a
kind of__________.
A. worm B. search engine C. service D. directory
35. The
disadvantage of Crawler is that it__________.
A. provides a complete database
B.
takes too much time to find the needed information
C. provides too much useless
information
D. gives response to every quest
36. Who can input information to
the web directories?
A. Only webmasters.
B. Both directory maintainers and
webmasters.
C. Any one who wants to announce a web page.
D. Any one who has
found a new web page.

Relaxation therapy ( = treatment). If you read the sentence out loud, your
blood pressure will go up. If you talk to another person, it will go still
higher. If the talk is with your boss, your pressure will go even higher. If you
speak to someone of the opposite sex, your pressure may show less change if you
’ re married than if you ’ re single. Dozens of times each day, your blood
pressure changes with what you ’ re feeling and doing. These “ ups and downs”
take place in everyone, but they are more severe in people with high blood
pressure. That discovery is the basis for the newest therapy: controlling blood
pressure by learning skills to control everyday stress. Many patients control
their blood pressure with the relaxation response. This takes four simple
things: a quiet environment, a comfortable position (sitting or lying down), the
repeating of a word, prayer or phrase each time you breathe and having none of
other thoughts. Something remarkable happens when you do this, according to
research in Boston. Relaxation of the mind and body has the effect that some
blood-p ressure pills would have. What ’ s more, the blood pressure stays lower,
just as it would with a pill, after you have stopped the relaxation and have
returned to the stress of daily life.
31. The first paragraph tells us the
reason why your blood pressure goes up is that__________.
A. you read aloud a
sentence
B. the man you talk to is your boss
C. you ’ re not married
D. you ’ re
nervous
32. Which of the following statements is not true?
A. One ’ s blood
pressure changes many times every day.
B. Your blood pressure changes with your
feelings.
C. When you ’ re doing different things, your blood pressure, perhaps,
is different.
D. The changes of blood pressure only happen to people with high
blood pressure.
33. The last paragraph tells us relaxation therapy__________.
A.
needs a new kind of medicine
B. has the same effect as blood-pressure pills
C.
is more than blood-pressure pills
D. is working and can be improved
