1、江苏省盱眙中学 2017 届高三实验班限时训练材料（20）（建议用 20 分钟完成 A、B 、C 三篇文章，鼓励同学们挑战 D 篇）ABelow are the four most famous bridges in the world.51. Of the four bridges, which one has the shortest history?A. Ponte Vecchio. B. Golden Gate Bridge. C. Millau Bridge. D. Charles Bridge.52. Which of the following statements is TRU
2、E about the Golden Gate Bridge?A. The span length ranks the 8th in the world. B. Its color enables travelers to see it easily on foggy days.C. It is the most popular tourist attraction in America. D. It took Joseph B. Strauss 7 years to design the bridge.Ponte Vecchio BridgeThe Ponte Vecchio (litera
3、lly “old bridge”) is a bridge built in the Middle Ages over the Arno River in Florence, Italy, the only Florentine bridge to survive World War II. The bridge is unique for still having shops built along it, as was common in the days of the Medici. Butchers originally occupied souvenir sellers. It is
4、 said that the economic concept of bankruptcy originated here: when a merchant could not pay his debts, the table on which he sold his goods was physically broken by soldiers, and this practice was called “bancorotto (broken table)”.Golden Gate BridgeThe Golden Gate Bridge is a suspension bridge spa
5、nning the Golden Gate, the strait between San Francisco and Marin County to the north. It is the masterwork of architect Joseph B. Strauss, whose statue graces the southern observation deck. The bridge took seven years to build, and was completed in 1937. The Golden Gate Bridge used to be the longes
6、t suspension bridge span in the world. And today it has become one of the most popular tourist attractions in San Francisco and California. Since its completion, the span length has been surpassed by eight other bridges. The famous red-orange color of the bridge was specifically chosen to make the b
7、ridge more easily visible through the thick frog that frequently covers the bridge.Millau BridgeStarted in 1998 and opened to traffic in 2005, the Millau Viaduct is a huge cable-stayed road-bridge that spans the valley of the river Tarn near Millau in southern France. It is the tallest highway bridg
8、e in the world, with the highest pylons summit at 343 metersslightly taller than the Eiffel Tower. The speed limit on the bridge was reduced from 130 km/h to 110 km/h because of traffic slowing down, due to tourists taking pictures of the bridge from the vehicles.Shortly after the bridge opened to t
9、raffic, passengers were stopping to admire the landscape and the bridge itself.Charles bridgeThe Charles Bridge is a famous stone Gothic bridge that crosses the Vltava River in Prague, Czech Republic. Its construction started in 1357 under the support of King Charles IV, and finished in the beginnin
10、g of the 15th century. As the only means of crossing the river Vltava, the Charles Bridge was the most important connection between the Old Town and the area around Prague Castle. Connection made Prague important as a trade route between Eastern and Western Europe. Today it is one of the most visite
11、d sights in Prague with painters, owners of kiosks and other traders alongside numerous tourists crossing the bridge.53. The Charles Bridge played an important role in Prague, Czech Republic because _.A. it attracted many famous painters there B. it was supported by Kin Charles IVC. it was the only
12、stone Gothic bridge crossing the Vltava RiverD. it promoted the trade between Eastern and Western EuropeBTELECOMMUTERS fall into two camps. Some sit on the sofa watching daytime soaps, pausing occasionally to check their BlackBerrys. Most, however, do real work, undistracted by meetings and talkativ
13、e colleagues.In the future more people will work from home. With office space in London and New York so costly, many firms save money by encouraging staff to work in their loose clothes. Instead of having to bury their noses in strangers armpits on crowded trains, they can work via e-mail, Skype and
14、 virtual private networks.Yet, in a research published in MIT Sloan Management Review, Daniel Cable of the London Business School shows that telecommuters are less likely to be promoted. In one experiment subjects were asked to judge scenarios in which the only difference was whether the employee wa
15、s at his office desk or at home. Managers rated those at the office to be more dependable and industrious, regardless of the quality of their work.Visibility creates the illusion of value. Being the last to leave the office impresses bosses, even if you are actually larking around (胡闹) on Facebook.
16、Oddly, this holds true at firms that explicitly encourage staff to work from home. Many Californian tech firms asked employees not to come to the office too often; yet bosses unconsciously punished those who obeyed.Remote workers understand this. Many frequently sent their bosses with progress repor
17、ts to prove they are on the job. A fifth of the workers in the study admitted to leaving an e-mail or voice mail early or late in the day. Still, many are not as smart as they think. Some choose a Monday or Friday to work at home. That, says Mr. Cable, makes others think they are eager to extend the
18、 weekend.A culture of presenteeism hurts working mothers most. Many women (and some men) work from home to allow themselves the flexibility to pick up kids from school. That need not mean they produce less; only that they do it at a time and a place of their own choosing. Some firms, such as Best Bu
19、y, an electronics retailer, recognize this and try hard to evaluate staff entirely on performance. But this is not easy. Intangibles such as teamworking skills matter, too. Mr. Cable thinks homeworking will lose its stigma (污名) only when most people do it. Or perhaps when the boss is telecommuting,
20、too.54. What is most likely the main cause of the increasing number of telecommuters?A. Increasing location rents. B. Annoying talkative colleagues.C. High-tech mobile phones. D. Attractive daytime soaps.55. What does the example of many California tech firms prove?A. Working at home is impractical
21、in tech firms. B. Employees presence at office raises their value.C. Employees should judge when to obey. D. Bosses often dont keep their promises.56. What do wise telecommuters do to prove they are on the job?A. They give timely accounts of their work progress to their bosses.B. They check their e-
22、mails and voice mails every day.C. They discuss the work with their bosses. D. They spend some time working on weekends.57. What is the biggest disadvantage of working at home according to the last paragraph?A. The traditional working culture can be hurt. B. Mothers work may be interrupted by their
23、kids.C. Retailers cant get enough on-site employees. D. Employees may lack chances to develop certain skills.CAlzheimers disease has no cure. There are, however, five drugsknown and approvedthat can slow down the development of its symptoms. The earlier such drugs are administered, the better. Unfor
24、tunately, the disease is usually first noticed when people complain to their doctors of memory problems. That is normally too late for the drugs to do much good. A simple and reliable test for Alzheimers that can be administered to everybody over the age of about 65, before memory-loss sets in, woul
25、d therefore be useful.Theo Luider, of the Erasmus University Medical Centre in Rotterdam, and his colleagues think they have found onebut it works only in women. They made their discovery, just reported in the Journal of Proteome Research, by tapping into a long-term, continuing study that started i
26、n 1995 with 1,077 non-demented and otherwise healthy people aged between 60 and 90. At the beginning of the project, and subsequently during the periods 1997-99 and 2002-04, participants were brought in for a battery of neurological (神经学的) and cognitive (认知的) investigations, physical examinations, b
27、rain imaging and blood tests.During the first ten years of the study, 43 of the volunteers developed Alzheimers diseases. When Dr. Luider compared blood samples from these people with samples from 43 of their fellow volunteers, matched for sex and age, who had remained Alzheimers-free, he found some
28、thing surprising. Levels of a substance called pregnancy zone protein (妊娠带蛋白) had been unusually high, even before their symptoms appeared, in some of those who went on to develop Alzheimers disease.Those “some”, it turned out, were all women. On average, levels of pregnancy zone protein in those wo
29、men who went on to develop Alzheimers were almost 60% higher than those of women who did not. In men, levels of the protein were the same for both.The reason for this curious result seems to be that the brain plaques (斑块) associated with Alzheimers disease are themselves turning out pregnancy zone p
30、rotein. Certainly, when Dr. Luider applied a chemical stain specific to that protein to the plaques of dead Alzheimers patients he found the protein present in them.Confusingly, though, it was there in the plaques of both sexes. Presumably, female cells (and therefore the plaques of female brains) m
31、ake more of it than male cells do. But that remains to be proved. Whatever the reason, however, this result means that women, at least, may soon be able to tell whether and when they are at risk of Alzheimers and thus do something about it before they start losing their minds.58. What can we learn f
32、rom the first paragraph?A. No medication can slow down the development of Alzheimers symptoms. B. To detect Alzheimers disease before memory loss appears is vital.C. Doctors had better handle Alzheimers disease when people are 65 years old. D. People who always complain are most likely to have Alzhe
33、imers disease. 59. The underlined word “one” in Paragraph 2 refers to _. A. a simple and reliable test for Alizheimers B. a possible cure for Alzheimers C. an important discovery about Alzheimers D. an effective and legal drug for Alzheimers 60. What does Dr. Luiders study tell us about the pregnanc
34、y zone protein?A. It wont go high until the symptoms of Alzheimers appear. B. In men, levels of it remain stable for their lifetime. C. Women developing Alzheimers usually have lower levels of it. D. The brain plaques connected with Alzheimers produce it. 61. The passage is mainly about _.A. patient
35、s of Alzheimers disease and its drugs B. an introduction to the pregnancy zone protein C. a new discovery concerning Alzheimers disease D. the development stages of Alzheimers disease DHe was in the first third-grade class I taught at Saint Marys School in Morris, Minnesota. All 34 of my students we
36、re dear to me, but Mark Eklund was one in a million. Very neat in appearance, he had that happy-to-be-alive attitude that made even his occasional mischievousness delightful.Mark also talked continuously. I had to remind him again and again that talking without permission was not acceptable. One mor
37、ning my patience was growing thin when Mark talked once too often, and then I made a novice-teachers mistake. I looked at Mark and said, “If you say one more word, I am going to tape your mouth shut!”It wasnt ten seconds later when Chuck blurted out, “Mark is talking again.” I hadnt asked any of the
38、 students to help me watch Mark, but since I had stated the punishment in front of the class, I had to act on it.I remember the scene as if it had occurred this morning. Without saying a word, I proceeded to Marks desk, tore off two pieces of tape and made a big X with them over his mouth. I then re
39、turned to the front of the room.As I glanced at Mark to see how he was doing, he winked at me. That did it! I started laughing. The entire class cheered as I walked back to Marks desk, removed the tape, and shrugged my shoulders. His first words were, “Thank you for correcting me, Sister.”At the end
40、 of the year I was asked to teach junior-high math. The years flew by, and before I knew it Mark was in my classroom again. He was more handsome than ever and just as polite.One Friday, things just didnt feel right. We had worked hard on a new concept all week, and I sensed that the students were gr
41、owing discouraged with themselvesand edgy with one another. I had to change the mood of the class before it got out of hand. So I asked them to list the names of the other students in the room on two sheets of paper, leaving a space between each name. Then I told them to think of the nicest thing th
42、ey could say about each of their classmates and write it down. It took the remainder of the class period to finish the assignment.That Saturday, I wrote down the name of each student on a separate sheet of paper, and I listed what everyone else had said about that individual. On Monday I gave each s
43、tudent his or her list. Some of them ran two pages. Before long, the entire class was smiling. “Really?” I heard whispers. “I never knew that meant anything to anyone!” “I didnt know others liked me so much!”No one ever mentioned those papers in class again. I never knew if the students discussed th
44、em after class or with their parents, but it didnt matter. The exercise had accomplished its purpose. The students were happy with themselves and one another again.That group of students moved on. Several years later, after I returned from a vacation, I got a call from my father. “The Eklunds called
45、 last night,” he began. “Really?” I said. “I havent heard from them for several years. I wonder how Mark is.”Dad responded quietly. “Mark was killed in Vietnam,” Mark looked so handsome, so mature. All I could think at that moment was, Mark, I would give all the masking tape in the world if only you
46、 could talk to me.After the funeral, most of Marks former classmates headed to Chucks farmhouse for lunch. Marks parents were there, obviously waiting for me. “Helen, we want to show you something,” his father said, taking a wallet out of his pocket. “They found this on Mark when he was killed. We t
47、hought you might recognize it.”Opening the billfold, he carefully removed two worn pieces of notebook paper that had obviously been taped, folded and refolded many times. I knew without looking that the papers were the ones on which I had listed all the good things each of Marks classmates had said
48、about him. “Thank you so much for doing that,” Marks mother said. “As you can see, Mark treasured it.”Marks classmates started to gather around us. Charlie smiled rather sheepishly and said, “I still have my list. Its in the top drawer of my desk at home.” Then Vicki, another classmate, reached into
49、 her pocket-book, took out her wallet and showed her worn and ragged list to the group. “I carry this with me at all times,” Vicki said without hesitation. “I think we all saved our lists.”Thats when I finally sat down and cried. I cried for Mark and for all his friends who would never see him again.62. We can conclude that when Sister Helen was a third-grade teacher, she _.A. was usually hot-tempered and impatient B. liked all the students in the class but MarkC. wasnt always sure how to discip
