Passage 9 Most libraries now take advantage of microfilm to store newspapers and other materials that would otherwise take up acres of valuable shelf space. If you aren39。t acquainted with the stuff, if the projector in the reference room has looked like an intimidating mystery, you should get to know it, for marvelous research opportunities are available to you if you do. If, for instance, you are writing a paper on World War II, wouldn39。 t it be great to see the front page of a newspaper for December 8, 1941, the day the . Congress declared war? Or to quote from an editorial published on that fateful day? Microfilm is small photographic film that contains the images of printed pages in reduced form. A whole week39。s file of daily newspapers can be preserved on a strip of microfilm two inches wide and seven or eight feet long. Wound into a roll and stashed in a small, labeled box, the microfilm can be stored in a few square inches of space. Microfilm saves books that otherwise39。 might be lost: it crumbles more slowly than paper does. It also permits the publication of monographs and dissertations (學(xué)位論文 ), which have small audiences, for less cost than printing. Complete files of historically important magazines that are now practically impossible to obtain are currently at the service of a small library. In many reference rooms, files of the New York Times and other frequently consulted newspapers and periodicals sit in microfilm boxes next to a viewing projector. The machine bears instructions, but if you need help getting the thing to work, ask a librarian. Once you have the film on the machine, you crank (啟動(dòng) ) till you e to the very page you are looking for. Some projection machines will print out a photocopy of any page. 1.

Science cannot really explain electricity, magism, and gravitation。 their effects can be measured and predicted, but of their nature no more is known to the modern scientist than to Thales who first speculated (設(shè)想 ) on the electrification of amber (琥珀 ). Most contemporary physicists reject the notion that man can ever discover what these mysterious forces really are. Electricity, Bertrand Russell says, “is not a thing, like St. Paul39。s Cathedral。 it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell.” Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from selfevident principles. He felt, for example, that it is a selfevident principle that everything in the universe has its proper place, hence one can deduce that objects fall to the ground because that39。s where they belong, and smoke goes up because that39。s where it belongs. The goal of Aristotelian science was to explain why things happen. Modern science was born when Galileo began trying to explain how things happen and thus originated the method of controlled experiment which now forms the basis of scientific investigation. 1. The purpose of the controlled experiment is . A) to explain why things happen B) to explain how things happen C) to forms the basis of scientific investigation D) to prove accepted theories 2. For two thousand years, scientific thought was most influenced by . A) selfevident principles. B) Thales39。 speculations. C) Aristotle39。s natural science. D) Russell39。s theory on electricity 3. Which of the following is true of Bertrand Russell39。s notion about electricity?
