For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and m
2、ark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets.A man-made chemical that attracts male gypsy moths by duplicating the natural attractant of female gypsy moths has been patented as No. 3,018,219.Dr. Martin Jacobson of Silver Spring, Md., assigned patent righ
3、ts to the U. S. Government as represented by the Secretary of Agriculture. The chemical can be used to detect gypsy moth infestations, as well as to control the insects.The gypsy moth does serious damage to forest and shade trees in New England and eastern New York State. The caterpillars, or larvae
4、, of gypsy moths eat the leaves of trees, often causing death by a single attack. Losses of hardwood trees have been estimated at tens of millions of dollars from a 20-year study.Gypsy moths were prevented from spreading to other U. S. forest areas by using the natural attractant of the female to de
5、tect infestations, then spraying with chemicals such as DDT to kill the insects.Since the lure could previously be obtained only by clipping the last two abdominal segments of the virgin female moth, extracting the segments with benzene and then processing to stabilize the chemical, the procedure wa
6、s expensive. Another difficulty was that, as the gypsy moth population declined, it became increasingly hard to obtain the females needed for lure production.Dr. Jacobson overcame both these difficulties by discovering a synthetic method for making the females attractant chemical. The chemical is kn
7、own as 12-acetoxy-l-hydroxycis-9- octadecene. It is so potent that the fraction of a drop produced by the female is 200,000 times more than the amount needed to catch a mate. The synthetic chemical is also very powerful-it works in amounts about equivalent to one drop in a box car.The flightless fem
8、ale gypsy moth mates only once a year and, as soon as she does, an enzyme switches off production of the sex attractant. The winged male, however, call mate several times and it is because of this that the chemical is being used for pest control.By using a mixture of attractant and DDT in traps line
9、d with a sticky substance, enough males can be caught to reduce the gypsy moth population substantially.（分数：4.00）(1).The damage done by gypsy moths to trees in New England and New York is done by _.（分数：1.00）A.only the male mothB.only the female mothC.a substitute female attractantD.caterpillars(2).P
10、rior to Dr. Jacobsons synthetic drug, scientists found difficulty in controlling the pest because _.（分数：1.00）A.the natural drug was unavailableB.female moths hid from the scientistsC.extracting the natural drug involved a complicated processD.the gypsy moth population declined(3).Dr. Jacobsons chemi
11、cal works by _.（分数：1.00）A.killing the caterpillarsB.attacking the larvaeC.killing the female mothD.attracting the male moth(4).We may assume that Dr. Jacobson assigned patent rights to the United States Government because he _.（分数：1.00）A.is a patriotic citizenB.is interested in pure researchC.is an
12、employee of the Department of AgricultureD.wants to destroy the gypsy mothUnlike the carefully weighed and planned compositions of Dante, Goethes writings have always the sense of immediacy and enthusiasm. He was a constant experimenter with life, with ideas, and with forms of writing. For the same
13、reason, his works seldom have the qualities of finish or formal beauty which distinguish the masterpieces of Dante and Virgil. He came to love the beauties of classicism, but these were never an essential part of his makeup. Instead, the urgency of the moment, the spirit of the thing, guided his pen
14、. As a result, nearly all his works have serious flaws of structure, of inconsistencies, of excesses and redundancies and extraneities.In the large sense, Goethe represents the fullest development of the romanticist. It has been argued that he should not be so designated because he so clearly mature
15、d and outgrew the kind of romanticism exhibited by Wordsworth, Shelley, and Keats. Shelley and Keats died young; Wordsworth lived narrowly and abandoned his early attitudes. In contrast, Goethe lived abundantly anti developed his faith in the spirit, his understanding of nature and human nature, and
16、 his reliance on feelings as mans essential motivating force. The result was all-encompassing vision of reality and a philosophy of life broader and deeper than the partial visions and attitudes of other romanticists. Yet the spirit of youthfulness, the impatience with close reasoning or “logic-chop
17、ping,“ and the continued faith in nature remained his to tile end, together with an occasional waywardness and impulsiveness and a disregard of artistic or logical propriety which savor strongly of romantic individualism. Since so many twentieth century thoughts and attitudes are similarly based on
18、the stimulus of the Romantic Movement, Goethe stands as particularly the poet of the modern man as Dante stood for medieval man and as Shakespeare for the man of the Renaissance.（分数：4.00）(1).The title that best expresses the main idea of this passage is _.（分数：1.00）A.Goethe and DanteB.The Characteris
19、tics of RomanticismC.Classicism versus RomanticismD.Goethe, the Romanticist(2).Goethes work shows a lack of _.（分数：1.00）A.inconsistenciesB.a vision of realityC.repetitionsD.formal polish(3).Goethe is called the poet of the modern man because _.（分数：1.00）A.he developed his faithB.he lived longer than S
20、helley and KeatsC.he presents many twentieth-century ideasD.avoidance of ideas(4).Good medieval writing was characterized by _.（分数：1.00）A.careful planningB.lack of beautyC.use of LatinD.avoidance of ideasThe coastlines on the two sides of the Atlantic Ocean present a notable parallelism: the eastern
21、most region of Brazil, in Pernambuco, has a convexity that corresponds almost perfectly with the concavity of the African Gulf of Guinea, while the contours of the African coastline between Rio de Oro and Liberia would, by the same approximation, match those of the Caribbean Sea.Similar corresponden
22、ces are also observed in many other regions of the earth. This observation began to awaken scientific interest about sixty years ago, when Alfred Wegener, a professor at the University of Hamburg, used it as a basis for formulating a revolutionary theory in geological science. According to Wegener,
23、there was originally only one continent or landmass, which he called Pangea. Inasmuch as continental masses are lighter than tile base on which they rest, he reasoned, they must float on the substratum of igneous rock, known as sima, as ice floes float on the sea. Then why, he asked, might continent
24、s not be subject to drifting? The rotation of the globe and other forces, he thought, had caused the cracking and, finally, the breaking apart of the original Pangea, along an extensive line represented today by the longitudinal submerged mountain range in the center of the Atlantic. While Africa se
25、ems to have remained static, the Americas apparently drifted toward the west until they reached their present position after more than 100 million years. Although the phenomenon seems fantastic, accustomed as we are to the concept of the rigidity and immobility of the continents, on the basis of the
26、 distance that separates them it is possible to calculate that the continental drift would have been no greater than two inches per year.（分数：4.00）(1).The title below that best expresses the main idea of this passage is _.（分数：1.00）A.A Novel TheoryB.PangeaC.Two Inches Per YearD.Static Africa(2).The su
27、bmerged mountain range in the Atlantic _.（分数：1.00）A.runs from east to westB.runs from north to southC.is proof of Professor Wegeners theoryD.is made up of igneous rock(3).Professor Wegeners theory is _.（分数：1.00）A.an attempt to explain many geographical parallelismsB.based on a study of 100 yearsC.an
28、 analysis of the lost continentD.unsound(4).Sima, as described in this passage, is _.（分数：1.00）A.the basic substance of PangeaB.like an ice floeC.the submerged mountain rangeD.igneous rockA little more than a century ago, Michael Faraday, a noted British physicist, managed to gain audience with a gro
29、up of high government officials, to demonstrate an electrochemical principle, in the hope of gaining support for his work.After observing the demonstration closely, one of the officials remarked bluntly, “Its a fascinating demonstration, young man, but just what practical application will come of th
30、is?“I dont know,“ replied Faraday, “but I do know that 100 years from now youll be taxing them.“From the demonstration of a principle to the marketing of products derived from that principle is often a long, involved series of steps. The speed and effectiveness with which these steps are taken are c
31、losely related to the history of management, the art of getting things done. Just as management applies to the wonders that have evolved from Faraday and other inventors, so it applied some 4,000 years ago to the workings of the great Egyptian and Mesopotamian import and export firms.to Hannibals re

33、ity, division of labor, discipline, unity of command, clarity of direction and the other basic factors that are so meaningful to management today. But the real impetus to management as an emerging profession was the Industrial Revolution. Originating in 18th-century England, it was triggered by a se
34、ries of classic inventions and new processes, among them John Kays Flying Shuttle in 1733, James Hargreaves Spinning Jenny in 1770, Samuel Cromptons Mule Spinner in 1779 and Edmund Cartwrights Power Loom in 1785.（分数：4.00）(1).The anecdote about Michael Faraday indicates that _.（分数：1.00）A.politicians

37、1.00）A.the problem of commandB.division of laborC.control by authorityD.competitionThanks to the protection of the tombs, so secure against the ravages of time if not against the hand of man, we possess a more complete sampling of Etruscan art in all its forms than we do of any other ancient Europea
38、n culture. Except for the frescoes of Pompeii and Herculaneum, the Etruscan frescoes supply the only insight we have into the techniques of painting in classical civilization. It is in southern Etruria, where the tombs were cut in the rock, that these frescoes are preserved. They are intact at least
39、 until the tomb is opened, whereupon deterioration begins. Fortunately it is now possible to remove the paintings from the walls and take them to the safety of the museum.The Etruscan painter used pleasantly simple mineral colors that be laid on a fresh layer of plaster applied to the rock wall. Wit
40、h large, uninterrupted surfaces to work on, he was prompted to make complex pictorial compositions. But his purpose is always clear. Enclosed forever in the tomb, his pictures were to evoke for the deceased the joys of life. The dead mans occupation, which he intended to resume in the afterlife, is
41、often depicted. Scenes of banquets and feasts are frequent. These guaranteed eternal satisfaction and pleasure to the departed; in the happy phrase of tile Belgian scholar Franz Cumont, “the ghost of a diner could be nourished by the appearance of food.“ The frescoes also perpetuated the pleasant ho
42、urs of sports, games and dances. When Etruria came on difficult times, the funerary frescoes took on a more somber tone: the features of the departed, which were formerly peaceful, were expressions of anxiety and even of anguish.Etruscan sculptors preferred to work in clay or bronze rather than in s
43、tone. They were particularly fond of the bas-relief, in which they produced delightfully animated figures framed in elegant arabesques. Their forte, however, was the portrait. The art of portraiture had deep funerary significance: it furnished a faithful image of the deceased to aid his survival in
44、the other life. Frequently, in the seventh century B. C. , the portrait of the deceased formed the lid of the crematory urn. Portraiture reached its peak in the last centuries of Etruscan civilization, when the characteristic Etruscan flair for detail, for the unusual, found its fullest expression.（
