尼日利亚人口超过1亿,经济以农矿业为主。
2014年11月20日,尼日利亚与我国正式签署了沿海铁路项目商务合同。
该项目总金额达119.7亿美元,全线采用中国铁路技术标准,是截至当时中国对外工程承包史上单体合同金额最大的项目。
下图示意尼日利亚铁路的分布。
(1)归纳尼日利亚现有铁路路网特点及作用。
(6分)(2)指出尼日利亚拟建沿海铁路的布局特点。
(6分)(3)简述尼日利亚沿海地区的气候特点,以及针对此气候特点,我国相关人员在建设该铁路时,为保障身体某某,需要防X的问题。
(6分)(4)指出因尼日利亚沿海铁路项目而可能获益的我国主要工业部门。
(4分)【答案】(22分)(1)路网特点:线路较少(密度较低);(2分)连接内陆和沿海港口。
(2分)作用:方便农产品出口和进口商品的运输。
(2分)(2)横贯沿海地区(或几乎与海岸线平行);(3分)连接东、西两条(通向内陆地区的纵向)铁路,构成铁路网。
(3分)(3)气候特点:(纬度低,属热带雨林气候)全年高温多雨。

(4分)(答对1项得1分,答对4项即可得4分。
本小题满分不得超过4分。
)【解析】试题分析:(1)读图可以看出尼日利亚现有铁路路网主要联系沿海和内地,线路少,密度较小,缺少沿海地区的横向联系;其作用主要是将内地初级农产品运到港口,供出口,同时方便进口商品运往内地。
(2)读图可以看出尼日利亚拟建沿海铁路整体上东西方向延伸,大致与海岸线平行,连接东、西两条通向内地地区的纵向铁路,构成铁路网。
(3)尼日利亚沿海地区的气候类型为热带雨林气候,其特点是终年高温多雨,气候湿热;湿热的气候有利于蚊虫繁殖,毒虫肆虐,病菌滋生,野生动植物数量多,体型较大,因而我国相关人员在建设该铁路时,为了保障身体某某,需要防X中暑、嗮伤、受潮、食物中毒、毒虫叮咬、野生动物侵袭、疫病、瘴气等,同时还应注意预防建设地区的自然灾害,如暴雨洪涝,山区还要预防滑坡、泥石流等地质灾害所带来的伤害。

The kids are shrieking, everyone is starving and your fridge contains nothing but a few squishy squashes and a limp carrot. So what do we all do? We give up and give in to some awful food choices that someone in some far-off factory or fast-food restaurant "cooked" without one bit of love in their heart. And this is making us sick and fat and it's killing us.Why not try HOME COOKED SUNDAYS? The idea is simple: Use the one day of the week we do have time to cook -- Sundays. Let's make it a fun bonding activity -- and a wildly productive and delicious one, too. Let's use Sundays to shop, prep and cook with our families (hey, everyone can pitch in!), and then enjoy a great sit-down dinner at the family table. Let's turn this into a cherished weekly ritual(惯例).To get people excited and cooking again, Kirstin Uhrenholdt (she is Danish and -- no kidding -- grew up on a fruit farm) and I wrote The Family Cooks, a cookbook filled with easy, healthy and tasty recipes.We included lots of tips and tricks to avoid an unhealthy week -- including how to avoid junk food hazards in the supermarket, and ways that small and big kids can help you cook. We know you have good ones, too. So let's share all our great ideas and inspire others to give it a try, because we know that Home Cooked Sundays will guarantee calmer and healthier weeknights -- and give us the perfect way to start the week connecting with our kids while teaching them a thing or two about health and happiness.Will you help make home-cooked meals synonymous with Sundays? Share your ideas, inspirations and best tips on how you prep your fridge on Sunday for a smooth week ahead. Send us your three best tips and favorite go-to recipe for Sunday dinner.We will post ours, and together, we'll make Home Cooked Sunday the single best and most delicious day of the week!56. The problem mentioned in Paragraph 2 is that .A. people give up cooking for many reasonsB. many people have been killed by fast foodC. there are only a few good fast-food restaurantsD. some people don’t know how to love and be loved57. The author advises readers to .A. attend a cooking competitionB. start cooking on Sundays regularlyC. buy the cookbook The Family CooksD. spend more time with families on SundaysBLee kuan Yew emerged onto the international stage as the founding father of the state of Singapore, then a city of about 1 million. He developed into a world statesman who acted as a kind of conscience to leaders around the globe.Fate initially seemed not to have provided him with a stage on which to achieve more than modest local success. In the first phase of decolonization, Singapore emerged as a part of Malaya. Itwas cut loose be cause of tensions between Singapore’s largely Chinese population and the Malay majority and, above all, to teach the city a lesson of dependency. Malaya undoubtedly expected that reality would cure Singapore of its independent spirit.But great men become such through visions beyond material calculations. Lee challenged conventional wisdom by opting for statehood. The choice reflected a deep faith in the virtues of his people. He asserted that a city located on a sandbar with no economic resource to draw upon, and whose major industry as a colonial naval base had disappeared, could nevertheless thrive (兴旺)and achieve international reputation by building on its principal asset(财富): the intelligence, industry and dedication of its people.A great leader takes his or her society from where it is to where it has never been — indeed, where it as yet cannot imagine being. By insisting on quality education, by suppressing corruption and by basing governance on merit, Lee and his colleagues raised the annual per capita income of their population from $500 at the time of independence in 1965 to roughly $55,000 today. In a generation, Singapore became an international financial center, the leading intellectual metropolis of Southeast Asia, the location of the region’s major hospitals and a favored site for conferences on international affairs. It did so by adhering to an extraordinary pragmatism: by opening careers to the best talents and encouraging them to adopt the best practices from all over the world.Superior performance was one component of that achievement. Superior leadership was even more important. As the decades went by, it was moving — and inspirational — to see Lee, the mayor of a medium-size city, become a mentor(导师) of global strategic order.The great tragedy of Lee’s life was that his beloved wife was felled by a stroke that left her a prisoner in her body, unable to communicate or receive communication. Through all that time, Lee sat by her bedside in the evening reading to her. He had faith that she understood despite the evidence to the contrary.Perhaps this was Lee Kuan Yew’s role in his era. He had the same hope for our world. He fought for its better instincts even when the evidence was ambiguous. But many of us heard him and will never forget him.58.Why did Lee Kuan Yew choose to lead Singapore to be independent?A.He intended to act as a kind of conscience to leaders around the globe.B.He determined his people shouldn’t be subjected to Malaya anymore.C.He had considerable confidence in the value of the city’s assets.D.He wanted Singapore to be the most powerful country worldwide.59.From the underlined sentence in Paragraph 2, we can know that__________.A. Malaya expected Singapore to be powerful.B. Malaya had a desire to kick Singapore off.C. Malaya firmly believed Singapore would give in.D. Malaya didn’t think Singapore possessed independent spirit.60.Which of the following can best describe Lee Kuan Yew?A. Stubborn and arbitrary.B. Aggressive and affectionate.C. Demanding and bossy.D. Outspoken and humorous.CScientists from the United States say they have found fish and other creatures living under icywaters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world's largest floating ice sheet.The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America's National Science Foundation." We chose a study site where, in the first year, we went into the subglacial(冰川下的) lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates, and how the sediment(沉淀物) underneath the ice sheet operates, as well, because it's the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean." says Ross Powell, who led the investigation. The team included scientists, engineers, mechanics and technicians. They used tractors to pull electric generators, science laboratories, heavy machinery and other supplies across the ice from the main U.S. scientific base at McMurdo Station to the researcher's camp.The camp was near a subglacial lake, where an earlier study took place.Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels."What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere."Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water, sediment and other material from the grounding zone.Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area.Reed Scherer says the video images they saw in the Command Center were a total surprise."It's a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive. Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active."This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating(退去的) ice have on them?Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues."We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past, relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will be some differences that we'll see in the history of the ice sheet from the sediment cores, once we open them up." But Ross Powell says the work raises more questions than it answers.61.Scientists conducted the three-month research at the Ross Ice Shelf with the intention of____________.A.predicting how climate change influences rising sea levels.B.finding out whether there are life forms existing deep under Antarctic ice.C.providing the speed of ice flowing into the ocean is controlled by water.D.discovering an explanation of the effect the melting ice has on sea level rise.62.What made the researchers surprised when they saw the video images?A.Researchers saw fish in the farthest south for the first time.B.A video camera was able to work well under deep icy waters.C.Sediment cores present differences in the history of the ice sheet.D.The drill should dig down 740 meters to collect things.63.From sediment cores taken from the grounding zone, scientists will probably know __________A.what the ice will do in the near future.B.the ice in the grounding zone is melting at the moment.C. some differences rarely exist in the history of the ice sheet.D.something about the creatures under icy water in Antarctica.64.What can be inferred from the passage?A. Scientists will conduct a follow –up study on the frozen continent.B. No creatures once appeared or lived in icy water in Antarctica.C. America’s National Science Foundation is in complete charge of the research.D. Researchers have found how the sediment underneath the ice sheet operate s.D“Have you put any salt in it?”“Certainly not, ma’am,”answered Marie, amazed by the question. “You told me yourself that I was never to put salt in it.”Upon this, Madame Duparc snatched up the saucepan without saying another word, turned to the cupboard, and stretched out her hand toward one of four salt-cellars which always stood there. Then she sprinkled salt into the saucepan--- or, if not salt something which she took for salt.The hasty-pudding made, Marie poured it from the saucepan into a soup-plate which her mistress held. Madame Duparc herself then took it to her father, Monsieur De Beaulieu. Then she and her daughter, and one of her sons, remained with the old man while he was eating his breakfast. Marie, left in the kitchen, prepared to clean the saucepan; but, before she could do so, she was suddenly called in two different directions by Madame De Beaulieu and Madame Duparc. The old lady wished to be taken to mass, and her mistress wanted to send her on a number of errands. It was half-past eleven in the forenoon before she got back to the kitchen.The first news that met her on her return was that Monsieur De Beaulieu had been suffering, ever since nine o’clock, from a violent attack of vomiting and colic. Madame Duparc ordered her to help the old man to bed immediately; and inquired, when these directions had been followed, whether Marie felt capable of looking after him herself, or whether she would prefer that a nurse should be sent for. Being a kind-hearted, willing girl, always anxious to make herself useful, Marie replied that she would gladly undertake the nursing of the old man; and thereupon her bed was moved at once into Monsieur De Beaulieu’room.Meanwhile Madame Duparc fetched from a neighboring apothecary’s one of the apprentices(学徒) of the shop to see her father. The apprentice was quite unfit to meet the emergency of the case, which was certainly serious enough to require the attention of his master, ifnot of a regularly qualified physician. Instead of applying and internal remedies, the apprentice stupidly tried blistering. This course of treatment proved utterly useless; but no better advice was called in. After he had suffered for hours without relief, Monsieur De Beaulieu began to sink rapidly toward the afternoon. At half-past five o’clock he had ceased to exist.This shocking catastrophe, startling and suspicious as it was, did not appear to disturb the nerves of Madame Duparc. She lost no time in sending for the nearest nurse to lay out the body of Monsieur De Beaulieu. On entering the chamber of death, the nurse found Marie there alone, praying by the old man’s bedside. “He died suddenly, did he not?” said the nurse. “Very suddenly”,answered Marie. “He was walking about only yesterday in perfect health.” Soon afterward the time came when it was customary to prepare supper. Marie went into the kitchen mechanically, to get the meal ready. Madame Duparc, her daughter, and her youngest son, sat down to it as usual. Madame De Beaulieu, overwhelmed by the dreadful death of her husband, was incapable of joining them.When supper was over, Marie assisted the old lady to bed. Then, worn out though she was with fatigue, she went back to the nurse to keep her company in watching by the dead body. Monsieur De Beaulieu had been kind to Marie, and had spoken gratefully of the little attentions she had shown him. She remembered this tenderly now that he was no more; and she could not find it in her heart to leave a hired mourner to be the only watcher by his death-bed. All that night she remained in the room, entirely ignorant of what was passing the while in every other part of the house—her own little bedroom included, as a matter of course.About seven o’clock the next morning, after sitting up all night, she went back again wearily to the kitchen to begin her day’s work. Her mistress joined her there, and saluted her instantly with a scolding.“You are the most careless, slovenly girl I ever met with.” Said Madame Duparc. “Look at your dress; how can you expect to be decent on a Sunday, if you wear your best pair of pockets on week-days?”65. What implication can we draw from the underlined sentence in Para.3?A. Salt was something necessary to make the hasty-pudding.B. Madame Duparc deliberately sprinkled salt into the saucepan.C. Salt was likely to be mistaken for other ingredients.D. Madame Duparc was criticizing Marie in a silent way.66. From the passage, we can learn that Marie_________________.A. intended to put salt into the hasty-puddingB. cleaned the saucepan after the breakfastC. fetched a physician from the apothecary’sD. had a busy day when the disaster happened67. Para.6 mainly tells us that________A. Monsieur De Beaulieu wasn’t properly treatedB. it was impossible to fetch a qualified physician thenC. the apprentice make a mistake during the treatmentD. Madame Duparc knew nothing about medical treatment68. When Monsieur De Beaulieu fell ill, _______A. Marie undertook the nursing of him willingly.B. all the family members were concerned about himC. the nurse knew exactly the reason for his illnessD. Marie was severely scolded for leaving him alone69. The cause of Monsieur De Beaulieu’s death probably lies in______A. Marie’s careless attendance on himB. the indifference from his wifeC. the salt previously put into his breakfastD. his old age and poor health condition70. According to the article, it’s safe to conclude that_____A. Madame Duparc was deeply worried about her fatherB. there was nothing suspicious in the old man’s deathC. the apprentice should answer for the old man’s deathD. something terrible was going to happen to Marie第二卷(非选择题共35分)第四部分:任务型阅读(共10小题;每小题1分,满分10分)The term bystander effect refers to the phenomenon in which the greater the number of people present, the less likely people are to help a person in distress. When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses. Being part of a large crowd makes it so no single person has to take responsibility for an action (or inaction).The most frequently cited example of the bystander effect in introductory psychology textbooks is the brutal murder of a young woman named Catherine "Kitty" Genovese. On Friday, March 13, 1964, 28-year-old Genovese was returning home from work. As she approached her apartment entrance, she was attacked and stabbed by a man later identified as Winston Moseley.Despite Genovese’s repeated calls for help, none of the dozen or so people in the nearby apartment building who heard her cries called police to report the incident. The attack first began at 3:20 AM, but it was not until 3:50 AM that someone first contacted police.While Genovese's case has been subject to numerous misrepresentations and inaccuracies, there have been numerous other cases reported in recent years. The bystander effect can clearly have a powerful impact on the general conduct of people in a society, but why exactly does it happen? Why don't we help when we are part of a crowd?There are several factors that contribute to the bystander effect. First, the presence of other people creates a diffusion of responsibility. Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present.The second reason is the need to behave in correct and socially acceptable ways. When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate. Other researchers have found that onlookers are less likely to intervene if the situation is ambiguous. In the case of Kitty Genovese, many of the 38 witnesses reported that they believed that they were witnessing a "lover's quarrel," and did not realize that the young woman was。
