The Egyptians made coarse fibers by 1600 B.C., and fibers survive as decorations on Egyptian pottery dating back to 1375 B.C. During the Renaissance (fifteenth and sixteenth centuries A.D.), glassmakers
2、from Venice used glass fibers to decorate the surfaces of plain glass vessels. However, glassmakers guarded their secrets so carefully that no one wrote about glass fiber production until the early seventeenth century.The eighteenth century brought the invention of spun glass fibers. R ne-Antoine de
3、 R a French scientist, tried to make artificial feathers from glass. He made fibers by rotating a wheel through a pool of molten glass, pulling threads of glass where the hot thick liquid stuck to the wheel. His fibers were short and fragile, but he predicted that spun glass fibers as thin as spider
4、 silk would be flexible and could be woven into fabric.By the start of the nineteenth century, glassmakers learned how to make longer, stronger fibers by pulling them from molten glass with a hot glass tube. Inventors wound the cooling end of the thread around a yarn reel, then turned the reel rapid
5、ly to pull more fiber from the molten glass. Wandering tradespeople began to spin glass fibers at fairs, making decorations and ornaments as novelties for collectors, but this material was of little practical use; the fibers were brittle, ragged, and no longer than ten feet, the circumference of the
6、 largest reels. By the mid-1870s, however, the best glass fibers were finer than silk and could be woven into fabrics or assembled into imitation ostrich feathers to decorate hats. Cloth of white spun glass resembled silver; fibers drawn from yellow-orange glass looked golden.Glass fibers were littl
7、e more than a novelty until the 1930s, when their thermal and electrical insulating properties were appreciated and methods for producing continuous filaments were developed. In the modern manufacturing process, liquid glass is fed directly from a glass-melting furnace into a bushing, a receptacle p
8、ierced with hundreds of fine nozzles, from which the liquid issues in fine streams. As they solidify, the streams of glass are gathered into a single strand and wound onto a reel.1. Which of the following aspects of glass fiber does the passage mainly discuss?(A) The major developments in its produc
9、tion(B) Its relationship with pottery making(C) Important inventors in its long history(D) The variety of its uses in modern industry2. The word coarse in line 1 is closest in meaning to(A) decorative(B) natural(C) crude(D) weak3. Why was there nothing written about the making of Renaissance glass f
10、ibers until the seventeenth century?(A) Glassmakers were unhappy with the quality of the fibers they could make.(B) Glassmakers did not want to reveal the methods they used.(C) Few people were interested in the Renaissance style of glass fibers.(D) Production methods had been well known for a long t
11、ime.4. According to the passage , using a hot glass tube rather than a wheel to pull fibers from moltenglass made the fibers(A) quicker to cool(B) harder to bend(C) shorter and more easily broken(D) longer and more durable5. The phrase this material in line 16 refers to(A) glass fibers(B) decoration
12、s(C) ornaments(D) novelties for collectors6. The word brittle in line 17 is closest in meaning to(A) easily broken(B) roughly made(C) hairy(D) shiny7. The production of glass fibers was improved in the nineteenth century by which of thefollowing(A) Adding silver to the molten glass(B) Increasing the
13、 circumference of the glass tubes(C) Putting silk thread in the center of the fibers(D) Using yarn reels8. The word appreciated in line 23 is closest in meaning to(A) experienced(B) recognized(C) explored(D) increased9. Which of the following terms is defined in the passage ?(A) invention (line 7)(B
14、) circumference (line 17)(C) manufacturing process (line 24)(D) bushing (line 25)PASSAGE 53 ACBDA ADBD托福阅读真题2Composers today use a wider variety of sounds than ever before, including many that were once considered undesirable noises. Composer Edgard Varse(1 883-1965) called thus the liberation of so
15、und.the right to make music with any and all sounds. Electronic music, for example made with the aid of computers, synthesizers, and electronic instruments may include sounds that in the past would not have been considered musical. Environmental sounds, such as thunder, and electronically generated
16、hisses and blips can be recorded, manipulated, and then incorporated into a musical composition. But composers also draw novel sounds from voices and nonelectronic instruments. Singers may be asked to scream, laugh, groan, sneeze, or to sing phonetic sounds rather than words. Wind and string players
17、 may lap or scrape their instruments. A brass or woodwind player may hum while playing, to produce two pitches at once; a pianist may reach inside the piano to pluck a string and then run a metal blade along it. In the music of the Western world, the greatest expansion and experimentation have invol
18、ved percussion instruments, which outnumber strings and winds in many recent compositions. Traditional percussion instruments are struck with new types of beaters; and instruments that used to be couriered unconventional in Western music tom-toms, bongos, slapsticks, maracasare widely used.In the se
19、arch for novel sounds, increased use has been made in Western music of microtones. Non-western music typically divides and interval between two pitches more finely than western music does, thereby producing a greater number of distinct tones, or microtones, within the same interval. Composers such a
20、s Krzysztof Penderecki create sound that borders on electronic noise through tone clusters closely spaced tones played together and heard as a mass, block, or band of sound. The directional aspect of sound has taken on new importance as well. Loudspeakers or groups of instruments may be placed at op
