单选题{{B}}Passage Four{{/B}} A recent history of the Chicago meat-packing industry and its workers examines how the industry grew from its appearance in the 1830's through the early 1890's. Meat-packers, the author argues, had good wages, working conditions, and prospects for advancement within the packinghouses, and did not cooperate with labor agitators since labor relations were so harmonious. Because the history maintains that conditions were above standard for the era, the frequency of labor disputes, especially in the mid-1880's, is not accounted for. The work ignores the fact that the 1880's were crucial years in American labor history, and that the packinghouse workers! efforts were part of the national movement for labor reform. In fact, other historical sources for the late nineteenth century record deteriorating housing and high disease and infant mortality rates in the industrial community, due to low wages and unhealthy working conditions. Additional date from the University of Chicago suggest that the packing houses were dangerous places to work. The government investigations commissioned by President Theodore Roosevelt which eventually led to the adoption of the 1906 Meat Inspection Act found the packinghouses unsanitary, while observed that most of the workers were poorly paid and overworked. The history may be too optimistic because most of its data date from the 1880's at the latest, and the information provided from that decade is insufficiently analyzed. Conditions actually declined in the 1880's, and continued to decline after the 1880's, due to are organization of the packing process and a massive influx of unskilled workers. The deterioration. In worker status, partly a result of the new availability of unskilled and hence cheap labor, is not discussed. Though a detailed account of work in the packing-houses is attempted, the author fails to distinguish between the wages and conditions for skilled workers and for those unskilled laborers who comprised the majority of the industry's workers from the 1880's on. While conditions for the former were arguably tolerable due to the strategic importance of skilled workers in the complicated slaughtering, cutting and packing process (though worker complaints about the rate and conditions of work were frequefit), pay and conditions for the latter were wretched. The author's misinterpretation of the origins of the feelings the meat-packers had for their industrial neighborhood may account for the history's faulty generalizations. The pride and contentment the author remarks upon were, arguably, less the products of the industrial world of the packers--the giant yards and the intricate plants--than of the unity and vibrancy of the ethnic cultures that formed a viable community on Chicago's South Side. Indeed, the strength of this community succeeded in generating a social movement that effectively confronted the problems of the industry that provided its livelihood.

单选题In width of scope, Yeats far exceeds any of his contemporaries. He is the only poet since the 18th century who has been a public man in his own country and the only poet since Milton who has been a public man at a time when his country was involved in a struggle for political liberty. This may not seem an important matter, but it is a question whether the kind of life lived by poets for the last two hundred years or so has not been one great reason for the drift of poetry away from the life of the community as a whole, and the loss of touch with tradition. Once the life of contemplation has been divorced from the life of action, or from real knowledge of men of action, something is lost which it is difficult to define, but which leaves poetry enfeebled and incomplete. Yeats responded with all his heart as a young man to the reality and the romance of Ireland's struggle but he lived to be completely disillusioned about the value of the Irish rebellion. He saw his dreams of liberty blotted out in horror by "the innumerable clanging wings that have put out the moon". It brought him to the final conclusion of the futility of all discipline that is not of the wlaole being, and of "how base at moments of excitement are minds without culture". But he remained a man to whom the life of action always meant something very real.

单选题Three 36 years ago Daniel Gabriel Fahrenheit made his 37 thermometer in his home town of Danzig (Now Gdansk in Poland). The thermometer was filled with 38 and completely sealed, but it was not much use without some sort of 39 to measure the temperature. One story 40 that, during the winter of 1708-09, Fahrenheit took a measurement of 0 degrees as the coldest temperature outdoors—which would now read as minus 17.8℃. Five years 41 he used mercury instead of alcohol for his 42 , and made a top reference point by measuring his own body temperature as 90 degrees. Soon afterwards he became a glassblower, 43 allowed him to make thinly blown glass tubes that could be marked up with more points on the scale and so 44 accuracy. Eventually he took the 45 point of his temperature scale from a reading made in ice, water and salt, and a top point made from the boiling point of water. The scale was recalibrated using 180 degrees between these 46 points and Fahrenheit was able to make much more accurate and more 47 measurements of temperature. But in 1742 a rival challenged the Fahrenheit scale and 48 superseded it. Anders Celsius, in Sweden, invented a scale of 100 degrees between the freezing and boiling points of water and gradually 49 over many countries. However, the British 50 wedded to Fahrenheit until well into the 20th century.

单选题In the United States, the first day nursery, was opened in 1854. Nurseries were established in various areas during the 1 half of the 19th century; most of 2 were charitable. Both in Europe and in the U.S., the day nursery movement received great 3 during the First World War, when 4 of manpower caused the industrial employment of unprecedented (前所未有) numbers of women. In some European countries nurseries were established 5 in munitions (军火) plants, under direct government sponsorship. 6 the number of nurseries in the U.S. also rose 7 , this rise was accomplished without government aid of any kind. During the years following the First World War, 8 , federal, State, and local governments gradually began to exercise a measure of control 9 the day nurseries, chiefly by 10 them. The 11 of the Second World War was quickly followed by an increase in the number of day nurseries in almost all countries, as women were 12 called up on to replace men in the factories. On this 13 the U.S. government immediately came to the support of the nursery schools, 14 $6,000,000 in July, 1942, for a nursery school program for the children of working mothers. Many States and local communities 15 this Federal aid. By the end of the war, in August, 1945, more than 100, 000 children were being cared 16 in daycare centers receiving Federal 17 . Soon afterward, the Federal government 18 cut down its expenditures for this purpose and later 19 them, causing a sharp drop in the number of nursery schools in operation. However, the expectation that most employed mothers would leave their 20 at the end of the war was only partly fulfilled.

单选题If you intend using humor in your talk to make people smile, you must know how to identify shared experiences and problems. Your humor must be relevant to the audience and should help to show them that you are one of them or that you understand their situation and are in sympathy with their point of view. Depending on whom you are addressing, the problems will be different. If you are talking to a group of managers, you may refer to the disorganized methods of their secretaries; alternatively if you are addressing secretaries, you may want to comment on their disorganized bosses. Here is an example, which I heard at a nurses" convention, of a story which works well because the audience all shared the same view of doctors. A man arrives in heaven and is being shown around by St. Peter. He sees wonderful accommodations, beautiful gardens, sunny weather, and so on. Everyone is very peaceful, polite and friendly until, waiting in a line for lunch, the new arrival is suddenly pushed aside by a man in a white coat, who rushes to the head of the line, grabs his food and stomps over to a table himself. "Who is that?" The new arrival asked St. Peter. "Oh, that"s God," came the reply, "but sometimes he thinks he"s a doctor." If you are part of the group which you are addressing, you will be in a position to know the experiences and problems which are common to all of you and it"ll be appropriate for you to make a passing remark about the inedible canteen food or the chairman"s notorious bad taste in ties. With other audiences you mustn"t attempt to cut in with humor as they will resent an outsider making disparaging remarks about their canteen or their chairman. You will be on safer ground if you stick to scapegoats like the Post Office or the telephone system. If you feel awkward being humorous, you must practice so that it becomes more natural. Include a few casual and apparently oK-the-cuff remarks which you can deliver in a relaxed and unforced manner. Often it"s the delivery which causes the audience to smile, so speak slowly and remember that a raised eyebrow or an unbelieving look may help to show that you are making a light-hearted remark. Look for the humor. It often comes from the unexpected. A twist on a familiar quote "If at first you don"t succeed, give up" or a play on words or on a situation. Search for exaggeration and understatements. Look at your talk and pick out a few words or sentences which you can turn about and inject with humor.
