一、春天终会来的,谁也阻挡不住那波涛一样的绿色旋律。
1.“一元复始,万象更新。
”春天给大自然带来生机,给人们带来希望,给社会带来新气象。
下列说法正确的是①春天万物复苏,惊蛰前后大多数蛰伏的动物开始活动②春风化雨润物无声,齐鲁大地的春雨是由印度洋上的暖湿气流带来的③“千门万户曈曈日,总把新桃换旧符。
”王安石的《元日》描写了元宵节的习俗④“莫道今年春将尽,明年春色倍还人。
”这两句诗可借以表达人们应对国际金融危机的信心A. ①②B. ①③C. ①④D. ③④解析:惊蛰反映自然物候现象的,含义是:春雷乍动,惊醒了蛰伏在土中冬眠的动物。
这时,气温回升较快,长江流域大部地区已渐有春雷。
我国南方大部分地区,常年雨水、惊蛰亦可闻春雷初鸣;而华南西北部除了个别年份以外,一般要到清明才有雷声,为我国南方大部分地区雷暴开始最晚的地区。
齐鲁大地的春雨是由太平洋上的暖湿气流带来的,我国西北部有一部分是北冰洋,我国西南地区大部分来自印度洋。
王安石的《元日》爆竹声中一岁除,春风送暖入屠苏。
千门万户曈曈日,总把新桃换旧符。
这是王安石的一首著名的诗作《元日》,“元日”就是阴历正月初一。
这是一首写古代迎接新年的即景之作,大约是王安石在神宗初年刚任宰相不久写的。
王安石《元日》描写人们欢庆元旦的情形,反映了挂年画,贴桃符,燃放鞭炮,穿新衣,往来拜年,守岁,正月初一喝屠苏酒这些风俗习惯。

In thinking about what was possible from Geneva, where we are based, we decided on a trip toIstanbul, a two-hour plane ride from Zurich.We envisioned the trip as a prelude to more exotic ones, perhaps to New Delhi or Bangkok later this year, but thought our 11- and 13-year-olds needed a first step away from manicured boulevards and pristine monuments.What we didn't foresee was the reaction of friends, who warned that we were putting our children "in danger," referring vaguely, and most incorrectly, to disease, terrorism or just the unknown. To help us get acquainted with the peculiarities of Istanbul and to give our children a chance to choose what they were particularly interested in seeing, we bought an excellent guidebook and read it thoroughly before leaving.Friendly warnings didn't change our planning, although we might have more prudently checked with the U.S. State Department's list of troublespots. We didn't see a lotof children among the foreign visitors during our six-day stay in Istanbul, but we found the tourist areas quite safe, very interesting and varied enough even to suit our son, whose oft-repeated request is that we not see "every single" church and museum in a given city.Vaccinations weren't needed for the city, but we were concemed about adapting to the water for a short stay. So we used bottled water for drinking and brushing our teeth, a precaution that may seem excessive, but we all stayed healthy.T aking the advice of a friend, we booked a hotel a 20-minute walk from most of Istanbul's major tourist sites. This not only got us some morning exercise, strolling over the Karakoy Bridge, but took us past a colorful assortment of fishermen, vendors and shoe shiners.From a teenager and pre-teen's view, Istanbul street life is fascinating since almost everything can be bought outdoors. They were at a good age to spend time wandering the labyrinth of the Spice Bazaar, where shops display mounds of pungent herbs in sacks. Doing this with younger children would be harder simply because the streets are so packed with people; it would be easy to get lost.For our two, whose buying experience consisted of department stores and shopping mall boutiques, it was amazing to discover that you could bargain over price and perhaps end up with two of something for the price of one. They also learned to figure out the relative value of the Turkish lira, not a small matter with its many zeros.Being exposed to Islam was an important part of our trip. Visiting the mosques, especially the enormous Blue Mosque, was our first glimpse into how this major religion is practiced. Our children's curiosity already had been piqued by the five daily calls to prayer over loudspeakers in every corner of the city, and the scarves covering the heads of many women.Navigating meals can be troublesome with children, but a kebab, bought on the street or in restaurants, was unfailingly popular. Since we had decided this trip was not for gourmets, kebabs spared us the agony of trying to find a restaurant each day that would suit the adults' desire to try something new amid children's insistence that the food be served immediately. Gradually, we branched out to try some other Turkish specialties.Although our son had studied Islam briefly, it is impossible to be prepared for every awkward question that might come up, such as during our visits to the Topkapi Sarayi, the Ottoman Sultans' palace. No guides were available so it was do-it-yourself, using our guidebook,which cheated us of a lot of interesting history and anecdotes that a professional guide could provide. Next time, we resolved to make such arrangements in advance.On this trip, we wandered through the magnificent complex, with its imperial treasures, its courtyards and its harem. The last required a bit of explanation that we would have happily lef~to a learned third party.11. The couple chose Istanbul as their holiday destination mainly becauseA. the city is not too far away from where they lived.B. the city is not on the list of the U.S. State Department.C. the city is between the familiar and the exotic.D. the city is more familiar than exotic.12. Which of the following statements is INCORRECT?A. The family found the city was exactly what they had expected.B. Their friends were opposed to their holiday plan.C. They could have been more cautious about bringing kids along.D. They were a bit cautious about the quality of water in the city.13. We learn from the couple's shopping experience back home thatA. they were used to bargaining over price.B. they preferred to buy things outdoors.C. street markets were their favourite.D. they preferred fashion and brand names.14. The last two paragraphs suggest that to visit places of interest in IstanbulA. guidebooks are very useful.B. a professional guide is a must.C. one has to be prepared for questions.D. one has to make arrangements in advance.15. The family have seen or visited all the following in Istanbul EXCEPTA. religious prayers.B. historical buildings.C. local-style markets.D. shopping mall boutiques.TEXT BLast month the first baby-boomers turned 60. The bulky generation born between 1946 and 1964 is heading towards retirement. The looming "demographic cliff" will see vast numbers of skilled workers dispatched from the labour force.The workforce is ageing across the rich world. Within the EU the number of workers aged between 50 and 64 will increase by 25% over the next two decades, while those aged 20-29 will decrease by 20%. In Japan almost 20% of the population is already over 65, the highest share in the world. And in the United States the number of workers aged 55-64 will have increased by more than half in this decade, at the same time as the 35- to 44-year-olds decline by 10%.Given that most societies are geared to retirement at around 65, companies have a looming problem of knowledge management, of making sure that the boomers do not leave before they have handed over their expertise along with the office keys and their e-mail address. A survey of human-resources directors by IBM last year concluded: "When the baby-boomer generation retires, many companies will find out too late that a career's worth of experience has walked out the door, leaving insufficient talent to fill in the void."Some also face a shortage of expertise. In aerospace and defence, for example, as much as 40% of the workforce in some companies will be eligible to retire within the next five years. At the same time, the number of engineering graduates in developed countries is in steep decline.A few companies are so squeezed that they are already taking exceptional measures. Earlier this year the Los Angeles Times interviewed an enterprising Australian who was staying in Beverly Hills while he tried to persuade locals to emigrate to Toowoomba, Queensland, to work for his engineering company there. Toowoomba today; the rest of thedeveloped world tomorrow?If you look hard enough, you can find companies that have begun to adapt the workplace to older workers. The AARP, an American association for the over-50s, produces an annual list of the best employers of its members. Health-care firms invariably come near the top because they are one of the industries most in need of skilled labour. Other sectors similarly affected, says the Conference Board, include oil, gas, energy and government.Near the top of the AARP's latest list comes Deere & Company, a no-nonsense industrial-equipment manufacturer based in Illinois; about 35% of Deere's 46,000 employees are over 50 and a number of them are in their 70s. The tools it uses to achieve that –flexible working, telecommuting, and so forth - also coincidentaUy help older workers to extend their working lives. The company spends "a lot of time" on the ergonomics of its factories, making jobs there less tiring, which enables older workers to stay at them for longer.Likewise, for more than a decade, Toyota, arguably the world's most advanced manufacturer, has adapted its workstations to older workers. The shortage of skilled labour available to the automotive industry has made it unusually keen to recruit older workers. BMW recently set up a factory in Leipzig that expressly set out to employ people over the age of 45. Needs must when the devil drives.Other firms are polishing their alumni networks. IBM uses its network to recruit retired people for particular projects. Ernst & Young, a professional-services firm, has about 30,000 registered alumni, and about 25% of its "experienced" new recruits are former employees who return after an absence.But such examples are unusual. A survey in America last month by Ernst & Young found that "although corporate America foresees a significant workforce shortage as boomers retire, it is not dealing with the issue." Almost three-quarters of the 1,400 global companies questioned by Deloitte last year said they expected a shortage of salaried staff over the next three to five years. Yet few of them are looking to older workers to fill that shortage; and even fewer are looking to them to fill another gap that has already appeared. Many firms in Europe and America complain that they struggle to find qualified directors for their boards - this when the pool of retired talent from those very same firms is growing by leaps and bounds.Why are firms not working harder to keep old employees? Part of the reason is that the crunch has been beyond the horizon of most managers. Nor is hanging on to older workers the only way to cope with a falling supply of labour. The participation of developing countries in the world economy has increased the overall supply - whatever the local effect of demographics in the rich countries. A vast amount of work is being sent offshore to such places as China and India and more will go in future. Some countries, such as Australia, are relaxing their immigration policies to allow much needed skills to come in from abroad. Others will avoid theneed for workers by spending money on machinery and automation.16.

It has two aspects: that of the wife who is more of a success than her husband and that of the wife who must rely heavily on her husband for help with domestic tasks. There are various ways in which the impact of the first difficulty can be reduced. Provided that husband and wife are not in the same or directly comparable lines of work, the harsh fact of her greater success can be obscured by a genial conspiracy to reject a purely monetary measure of achievement as intolerably crude. Where there are ranks, it is best if the couple work in different fields so that the husband can find some special reason for the superiority of the lowest figure in his to the most elevated in his wife's.(2) A problem that affects a much larger number of working wives is the need to re-allocate domestic tasks if there are children. In The Road to Wigan Pier George Orwell wrote of the unemployed of the Lancashire coalfields: "Practically never ... in aworking-class home, will you see the man doing a stroke of the housework. Unemployment has not changed this convention, which on the face of it seems a little unfair. The man is idle from morning to night but the woman is as busy as ever - more so, indeed, because she has to manage with less money. Yet so far as myexperience goes the women do not protest. They feel that a man would lose his manhood if, merely because he was out of work, he developed in a 'Mary Ann'."(3) It is over the care of young children that this re-allocation of duties becomes really significant. For this, unlike the cooking of fish fingers or the making of beds, is an inescapably time-consuming occupation, and time is what the fully employed wife has no more to spare of than her husband.(4) The male initiative in courtship is a pretty indiscriminate affair, something that is tried on with any remotely plausible woman who comes within range and, of course, with all degrees of tentativeness. What decides the issue of whether a genuine courtship is going to get under way is the woman's response. If she shows interest the engines of persuasion are set in movement. The truth is that in courtship society gives women the real power while pretending to give it to men.(5) What does seem clear is that the more men and women are together, at work and away from it, the more the comprehensive amorousness of men towards women will have to go, despite all its past evolutionary services. For it is this that makes inferiority at work abrasive and, more indirectly, makes domestic work seem unmanly, if there is to be an equalizing redistribution of economic and domestic tasks between men and women there must be a compensating redistribution of the erotic initiative. If women will no longer let us beat them they must allow us to join them as the blushing recipients of flowers and chocolates.21. Paragraph One advises the working wife who is more successful than her husband toA. work in the same sort of job as her husband.B. play down her success, making it sound unimportant.C. stress how much the family gains from her high salary.D. introduce more labour-saving machinery into the home.22. Orwell's picture of relations between man and wife in Wigan Pier (Paragraph Two) describes a relationship which the author of the passageA. thinks is the natural one.B. wishes to see preserved.C. believes is fair.D. is sure must change.23. Which of the following words is used literally, NOT metaphorically?A. Abrasive (Paragraph Five).B. Engines (Paragraph Four).C. Convention (Paragraph Two).D. Heavily (Paragraph One).24. The last paragraph stresses that if women are to hold important jobs, then they mustA. sometimes make the first advances in love.B. allow men to flirt with many women.C. stop accepting presents of flowers and chocolates.D. avoid making their husbands look like "Mary Anns".25. Which of the following statements is INCORRECT about the present form of courtship?A. Men are equally serious about courtship.B. Each man "makes passes" at many women.C. The woman's reaction decides the fate of courtship.D. The man leaves himself the opportunity to give up the chase quickly.TEXT DFrom Namche Bazaar, the Sherpa capital at 12,000 feet, the long line threaded south,dropping 2,000 feet to the valley floor, then trudged down the huge Sola-Khumbu canyon until it opened out to the lush but still daunting foothills of Central Nepal.It was here at Namche that one man broke rank and leaned north, slowly and arduously climbing the steep walls of the natural amphitheater behind the scatter of stone huts, then past Kunde and Khumjong.Despite wearing a balaclava on his head, he had been frequently recognized by the Tibetans, and treated with the gravest deference and respect. Even among those who knew nothing about him, expressions of surprise lit up their dark, liquid eyes. He was a man not expected to be there.Not only was his stature substantially greater than that of the diminutive Tibetans, but it was also obvious from his bearing - and his new broadcloak, which covered a much-too-tight army uniform - that he came from a markedly loftier station in life than did the average Tibetan. Among a people virtually bereft of possessions, he had fewer still, consisting solely of a rounded bundle about a foot in diameter slung securely by a cord over his shoulder. The material the bundle was wrapped in was of a rough Tibetan weave, which did not augur that the content was of any greater value - except for the importance he seemed to ascribe to it, never for a moment releasing his grip.His objective was a tiny huddle of buildings perched halfway up an enormous valley wall across from him, atop a great wooded spur jutting out from the lower lap of the 22,493-foot AmaDablum, one of the most majestic mountains on earth. There was situated Tengboche, the most famous Buddhist monastery in the Himalayas, its setting unsurpassed for magnificence anywhere on the planet.From the top of the spur, one's eyes sweep 12 miles up the stupendous Dudh Kosi canyon to the six-mile-long granite wall of cliff of Nuptse at its head. If Ama Dablum is the Gatekeeper,then the sheer cliff of Nuptse, never less than four miles high, is the Final Protector of the highest and mightiest of them all: Chomolongma, the Mother Goddess of the World, to the Tibetans; Sagarmatha, the Head of the Seas, to the Nepalese; and Everest to the rest of us. And over the great barrier of Nuptse She demurely peaks.It was late in the afternoon - when the great shadows cast by the colossal mountains were descending into the deep valley floors - before he reached the crest of the spur and shuffled to a stop just past Tengboche's entrance gompa. His chest heaving in the rarefiedair, he removed his hand from the bundle--the first time he had done so - and wiped grimy rivulets of sweat from around his eyes with the fingers of his mitted hand.His narrowed eyes took in the open sweep of the quiet grounds, the pagoda-like monastery itself, and the stone buildings that tumbled down around it like a protective skirt. In the distance the magic light of the magic hour lit up the plume flying off Chomolongma's 29,029-foot-high crest like a bright, welcoming banner.His breathing calmed, he slowly, stiffly struggled forward and up the rough stone steps to the monastery entrance. There he was greeted with a respectful nameste -"I recognize the divine in you" - from a tall, slim monk of about 35 years, who hastily set aside a twig broom he had been using to sweep the flagstones of the inner courtyard. While he did so, the visitor noticed that the monk was missing the small finger on his left hand. The stranger spoke a few formal words in Tibetan, and then the two disappeared inside.Early the next morning the emissary - lightened of his load - appeared at the monastery entrance, accompanied by the same monk and the elderly abbot. After a bow of his head, which was returned much more deeply by the two ocher-robed residents, he took his leave. The two solemn monks watched, motionless, until he dipped over the ridge on which the monastery sat, and out of sight.Then, without a word, they turned and went back inside the monastery.26. Which of the following words in Paragraph One implies difficulty in walking?A. "threaded".B. "dropping".C. "trudged".D. "daunting".27. In the passage the contrast between the Tibetans and the man is indicated in all the following aspects EXCEPTA. clothing.B. height.C. social statusD. personal belongings.28. It can be inferred from the passage that one can get ______ of the region from the monastery.A. a narrow viewB. a hazy viewC. a distant viewD. a panoramic view29. Which of the following details shows that the man became relaxed after he reached the monastery?A. "...he reached the crest of the spur and shuffled to a stop..."B. "...he removed his hand from the bundle..."C. "His narrowed eyes took in the open sweep of the quiet grounds..."D. "...he slowly, stiffly struggled forward and up the rough stone steps..."30.
