26、th bacteria. Where do these bacteria come from, since they are not seen in fresh food? Even until the mid-nineteenth century, many people believed that such microorganisms originated by spontaneous (5) generation ,a hypothetical process by which living organisms develop from nonliving matter. The mo

27、st powerful opponent of the theory of spontaneous generation was the French chemist and microbiologist Louis Pasteur(1822-1895).Pasteur showed that structures present in air closely resemble the microorganisms seen in putrefying materials .He did (10)this by passing air through guncotton filters, th

28、e fibers of which stop solid particles. After the guncotton was dissolved in a mixture of alcohol and ether, the particles that it had trapped fell to the bottom of the liquid and were examined on a microscope slide .Pasteur found that in ordinary air these exists a variety of solid structures rangi

29、ng in size from 0.01 mm to more than 1.0 mm .Many of these bodies resembled the reproductive (15)structures of common molds, single-celled animals, and various other microbial cells. As many as 20 to 30 of them were found in fifteen liters of ordinary air ,and they could not be distinguished from th

30、e organisms found in much larger numbers in putrefying materials .Pasteur concluded that the organisms found in putrefying materials originated from the organized bodies present in the air .He postulated that these bodies are constantly (20)being deposited on all objects. Pasteur showed that if a nu

31、trient solution was sealed in a glass flask and heated to boiling to destroy all the living organisms contaminating it, it never putrefied .The proponents of spontaneous generation declared that fresh air was necessary for spontaneous generation and that the air inside the sealed flask was affected

32、in some way (25)by heating so that it would no longer support spontaneous generation. Pasteur constructed a swan-necked flask in which putrefying materials could he heated to boiling, but air could reenter. The bends in the neck prevented microorganisms from getting in the flask Material sterilized

33、in such a flask did not putrefy. （分数：0.99）(1).What does the passage mainly discuss?（分数：0.09）A.Pasteurs influence on the development of the microscope.B.The origin of the theory of spontaneous generation.C.The effects of pasteurization on food.D.Pasteurs argument against the theory of spontaneous gen

35、d?B.How many types of organisms can be found on food?C.What is the most effective way to prepare living organisms for microscopic examination?D.How long can food stand before it putrefies?(4).The word “resemble“ in line 9 is closest in meaning to（分数：0.09）A.benefit fromB.appear similar toC.join toget

36、her withD.grow from(5).The purpose of the “guncotton“ mentioned in paragraph 2 was to（分数：0.09）A.trap particles for analysisB.slow the process of putrefactionC.increase the airflow to the microscopic slideD.aid the mixing of alcohol and ether(6).The author mention “l.0mm“ in line 14 in describing the

37、（分数：0.09）A.thickness of a layer of organisms that was deposited on an objectB.diameter of the fibers that were in the guncotton filtersC.thickness of the microscope slides that were usedD.size of the particles that that were collected(7).The word “postulated“ in line 19 is closest in meaning to（分数：0

38、.09）A.analyzedB.doubtedC.persuadedD.suggested(8).The objects that Pasteut removed from the air in his experiment were remarkable because they were（分数：0.09）A.primarily single-celled organismsB.no different from objects found in putrefying materialsC.fairly rareD.able to live in a mixture of alcohol a

39、nd ether(9).The word “it“ in line 22 refers to（分数：0.09）A.a nutrient solutionB.a glass flaskC.boilingD.spontaneous generation(10).According to paragraph 3,proponents of spontaneous generation believed that which of the following was important for the process to succeed ?（分数：0.09）A.A sealed containerB

40、.Fresh airC.HeatD.The presence of nutrients(11).It can be inferred from paragraph 3 that Pasteur employed a swam-necked flask to（分数：0.09）A.store sterilized liquids for use in future experimentsB.prevent heat from building up in a solutionC.disprove a criticism of his conclusionsD.estimate the number

41、 of organisms in a liter of airOf all modern instruments, the violin is apparently one of the simplest. It consists in essence of a hollow, varnished wooden sound box, or resonator, and a long neck, covered with a fingerboard, along which four strings are stretched at high tension. The beauty of des

42、ign, shape, and decoration is no accident: the proportions of the instrument are (5) determined almost entirely by acoustical considerations. Its simplicity of appearance is deceptive. About 70 parts are involved in the construction of a violin, Its tone and its outstanding range of expressiveness m

43、ake it an ideal solo instrument. No less important. however, is its role as an orchestral and chamber instrument. In combination with the larger and deeper-sounding members of the same family, the violins form the nucleus (10)of the modern symphony orchestra. The violin has been in existence since a

44、bout 1550. Its importance as an instrument in its own right dates from the early 1600s, when it first became standard in Italian opera orchestras. Its stature as an orchestral instrument was raised further when in 1626 Louis XIII of France established at his court the orchestra known as Les vingt-qu

45、atre (15)violons du Roy (The Kings 24 Violins), which was to become widely famous later in the century. In its early history, the violin had a dull and rather quiet tone resulting from the fact that the strings were thick and were attached to the body of the instrument very loosely. During the eight

46、eenth and nineteenth century, exciting technical changes were inspired (20)by such composer-violinists as Vivaldi and Tartini. Their instrumental compositions demanded a fuller, clearer, and more brilliant tone that was produced by using thinner strings and a far higher string tension. Small changes

47、 had to be made to the violins internal structure and to the fingerboard so that they could withstand the extra strain. Accordingly, a higher standard of performance was achieved, in terms of both facility (25)and interpretation. Left-hand technique was considerably elaborated, and new fingering pat

48、terns on the fingerboard were developed for very high notes. （分数：0.99）(1). The word “standard“ in line 12 is closest in meaning to（分数：0.09）A.practicalB.customaryC.possibleD.unusual(2). “The Kings 24 Violins“ is mentioned in line 15 to illustrate（分数：0.09）A.how the violin became a renowned instrumentB

49、.the competition in the 1600s between French and Italian orchestrasC.the superiority of French violinsD.why the violin was considered the only instrument suitable to be played by royalty(3). What is the main idea presented in paragraph 3?（分数：0.09）A.The violin has been modified to fit its evolving musical functions.B.The violin is probably the best known and most widely distributed musical instrument in the world.C.The violin
