Passage Two
For laymen ethnology is probably the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentation in laboratories .
The field workers have had some handicaps in winning respect for themselves. For a long
time they were considered as little better than amateur animal-watchers-- certainly not scientists since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast rule that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results . Of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can't be, or the homing of animals over long distances, or even details of spontaneous family relationships. Since these never can be reproduced in a laboratory, are they then not worth knowing about.
The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually and released. Motion pictures, often in color, provide permanent records of their subsequent activities . Recording of the animals' voices by electrical
sound equipment is considered essential , and the most meticulous notes are kept of all that occur. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other's observations right there in the field.
Ethnology , the word ,is derived from the Greek ethos, meaning the characteristic traits or features which distinguish a group -- any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying "the whole sequence of acts which constitute an animal's behavior." In abridged dictionaries ethnology is sometimes defined simply as "the objective study of animal behavior," and ethnologists do emphasize their wish to eliminate myths .

A. people who sand aside B. people who are not trained as biologists

32. According to the passage ,ethnology is________
A. a new branch of biology B. an old Greek science

A. ethnologists when working in the field are handicapped
B. ethnologists have problems in winning recognition as scientists
C. ethnologists are looked down upon when they work in the field
D. ethnologists meet with lots of difficulties when doing field work
34. According to the explanation of the scientific rule of experiment in the passage,
"hard-and-fast" means experiment procedures _____.
A. are difficult and quick to follow
B. must be carried out in a strict and quick way
C. must be followed strictly to avoid false and loose results
D. hard and unreasonable for scientists to observe
35. The meaning of the underlined words in "the details of spontaneous family relationships " can be expressed as____
A. natural family relationships
B. quickly occurring family relationships
C. animals acting like a natural family
D. animal family behavior that cannot be preplanned or controlled
Passage Three
The single greatest shift in the history of mass-communication technology occurred in the 15th century and was well described by Victor Hugo in a famous chapter of "Notre-Dame de Paris" It was a cathedral. On all parts of the giant building, statuary and stone representations of
every kind, combined with huge windows of stained glass, told the stories of the Bible and the
saints, displayed the intricacies of Christian theology, adverted to the existence of highly unpleasant demonic winged creatures, referred diplomatically to the majesties of political power,
and, in addition, by means of bells in bell towers, told time for the benefit of all of Paris and much
of France. It was an awesome engine of communication.
Then came the transition to something still more awesome. The new technology of mass
communication was potable, could sit on your table, and was easily replicable, and yet, paradoxically, contained more information, more systematically presented, than even the largest of
cathedrals. It was the printed book. Though it provided no bells and could not tell time, the
over-all superiority of the new invention was unmistakable.
In the last ten or twenty years, we have been undergoing a more or less equivalent shift -- this time to a new life as a computer-using population. The gain in portability, capability, ease,
orderliness, accuracy, reliability, and information-storage over anything achievable by pen scribbling, typewriting, and cabinet filing is recognized by all. The progress for civilization is undeniable and, plain]y, irreversible. Yet, just as the book's triumph over the, cathedral divided people into two groups, one of which prospered, while the other lapsed into gloom, the computer's triumph has also divided the human race.
You have only to bring a computer into a room to see that some people begin at once to buzz with curiosity and excitement, sit down to conduct experiments, ooh and ah at the boxes and beeps, and master the use of the computer or a new program as quickly as athletes playing a delightful new game. But how difficult it is - how grim and frightful! -- for the other people, the defeated class, whose temperament does not naturally respond to computers. The machine whirrs and glows before them and their faces twitch. They may be splendidly educated , as measured by book-reading, yet their instincts are all wrong, and no amount of manual-studying and mouse-clicking will make them right. Computers require a sharply different set of aptitudes, and, if the aptitudes are missing, little can be done, and misery is guaranteed.
Is the computer industry aware that computers have divided mankind into two new, previously unknown classes, the computer personalities and the non-computer personalities? Yes, the industry knows this. Vast sums have been expended in order to adapt the computer to the limitations of non-computer personalities . Apple's Macintosh, with its zooming animations and
pull-down menus and little pictures of file folders and watch faces and trash cans, pointed the way. Such seductions have soothed the apprehensions of a certain number of the computer-averse. This spring, the computer industry's. efforts are reaching a culmination of sorts .Microsoft Bill Gates' giant corporation , is to bring out a program package called Microsoft Bob, desired by Mr. Gates' wife, Melinda French, and intended to render computer technology available even to people who are openly terrified of computers. Bob's principle is to take the several tasks of operating a computer, rename them in a folksy style, and assign to them the images of an ideal room in an ideal home, with furniture and bookshelves, and with chummy cartoon helpers ("Friend, of Bob") to guide the computer user over the rough spots, and, in that way, simulate an atmosphere that feels nothing like computers .
36. According to this passage, which of the following statements is NOT TRUE?
A. It is because the cathedral of Notre-Dame in Paris had many bell-towers and could tell
time to people that the writer regards it as an engine of mass communication.
B. From cathedrals to books to computers the technology of communication has become
more convenient, reliable and fast
C. Every time when a new communication means triumphed over the old, it divided
mankind into two groups.
D. Computer industry has been trying hard to make people accept computers.
37. The printed book is more progressive than the cathedral as a communication means, because
A. it could sit on your table and did no longer tell time
B. it was more reliable and did not tell the stories of saints and demons
C. it was small, yet contained more information
D. it did not flatter religious and political power
38. The word "awesome" in the passage means_______
A. frightening B. causing fear and respect
C. amazingly new D. awful |
