2021年上海市春季高考英语冲关试题

2021年上海市春季高考英语冲关试题学校:___________姓名：___________班级：___________考号：___________一、用单词的适当形式完成短文Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Start with the end and work backwardsWhen Jason Hoelscher was an undergraduate of fine art studies, there weren’t any professional deve lopment classes. So ambition and the timely realization 1．he would have to determine “what’s next” on his own urged Jason to engage his future self to find direction. It was 1996, and he was finishing his BFA (Bachelor of Fine Art) in Denver. He was faced with the choice of sitting back to wait for something 2．(happen), or pursuing a path into the unknown. He chose the latter.Jason set up a plan that in five years he 3．(show) his work in the top gallery in that area of the country. This five-year goal gave him a starting point 4．which to work backwards.By setting the goal, all of Jason’s efforts 5．(point) in the same direction. He showed up at different art show openings, and researched as best he could to make 6．familiar with the market environment.As a result of showing up, Jason took opportunities 7．got him closer to his goal. He sent work to a student show and was accepted by Robin Rule, the owner of Rule Gallery. 8．(inspire), Jason spent the next month making new work.In April of 1997, Jason went back to Rule Gallery with his new work. 9．scared to death, he looked confident at the gallery meeting. When he left, he left as the newest addition to the rule gallery roster (花名册). He had his first exhibition there one year later.Jason could have stopped with the show selection, but what he really wanted was gallery representation. He struck while the iron was hot, and in 10．(do) so, shortened his five-year plan into a year-and-a-half.二、选用适当的单词或短语补全短文Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.Bill Drayton believes we’re in the middle of a necessary but painful historical transition. For millenniums most people’s lives had a certain 11．. You went to school to learn a trade or a skill-baking, farming or accounting. Then you could go into the workforce and make a good living repeating the same skill over the course of your career.But these days machines can do pretty much anything that’s 12．. The new world requires a different sort of person. Drayton calls this new sort of personal changemaker.Changemakers are people who can see the patterns around them, identify the problems in any situation, figure out ways to solve the problems in any situation, figure out ways to solve the problem, organize fluid teams, lead collective action and then 13．adapt as situations change.For example, Ashoka fellow Andrés Gallardo is a Mexican who lived in a high crime neighborhood. He created an app, called Haus, that allows people to 14．with their neighbors. The app has a panic button that 15．everybody in the neighborhood when a crime is happening. It allows neighbors to organize, chat, share crime statistics and work together.To form and lead this community of communities, Gallardo had to possess what Drayton calls “cognitive empathy-based living for the good of all.” Congnitive empathy is the ability to perceive how people are feeling in 16．circumstances. “For the good of all” is the capacity to b uild teams.It doesn’t matter if you are working in the cafeteria or the inspection line of a plant, companies will now only hire people who can 17．problems and organize responses.Millions of people already live with the mind-set. But a lot of people still inhabit the world of following rules and repetitive skills. They hear society telling them: We don’t need you. We don’t need your kids, either.” Of course, those people go into reactionary mode and strike back.The central 18．of our time, Drayton says, is to make everyone a changemaker. In an earlier era, he says, society realized it needed universal 19．. Today, schools have to develop the curriculums and assessments to make the changemaking mentality universal. They have to understand this is their criteria for success.Ashoka has studied social movements to find out how this kind of 20．shift can be promoted. It turns out that successful movements take similar steps.三、完形填空More people are travelling than ever before, and lower harriers to entry and falling costs means they are doing so for 21 periods.The rise of “city breaks” --48-hour bursts of foreign cultures, easier on the pocket and annual leave balance has increased tourist numbers, but not their 22 spread. The same attractions have been used to market cities such as Paris, Barcelona and Venice for decades, and visitors use the same infrastructure as residents to reach them. “Too many people do the same thing at the exact same time,” says Font. “For 23 , the city no longer b elongs to them.”This starts with marketing, says Font, who notes that Amsterdam has started advising visitors to seek 24 outside of the city centre on its official website. “That takes some balls, really to do that. But only so many people will look at the website, and it means they can say to their residents they’re doing all they can to ease congestion.”But it also 25 a better way, it is called “detourism”: sustainable travel tips an 26 itineraries for exploring an authentic Venice, off the paths beaten by the 28 million visitors who flock there each year.A greater variety of 27 for prospective visitors ------ ideas for what to do in off-peak seasons, for example, or outside of the city center ------ can have the effect of diverting them from already saturated landmarks, or 28 short breaks away in the first place. Longer stays 29 the pressure, says Font. If you go to Paris for two days, you’re going to go to the Eiffel Tower. “If you go for two weeks, you’re not going to go to the Eiffel Tower 14 times.”Similarly, repeat visitors have a better sense of the 30 , “We should be asking how we get tourists to 31 , not how to get them to come for the first time. If they’re coming for the fifth time, it is much easier to integrate their behavior with ours.”Local governments can foster this sustainable activity by giving preference to responsible operator and even high-paying consumers. Font says cities could stand to be more selective about the tourists they try to attract when the current metric for marketing success is how many there are, and how far they’ve come. “You’re thinking, ‘yeah but at what cost...’.”He points to unpublished data from the Barcelona Tourist Board that prioritizes Japanese tourists for spending an average of €40 more per day than French tourist as a(n) 32 that fails to take into account their bigger carbon footprint. 33 tourists are also more likely to be repeat visitors that come at off-peak times, buy local produce, and 34 to less crowded parts of the city ------ all productive steps towards more 35 tourism, and more peaceful relations with residents.21．A．longer B．shorter C．wider D．clearer22．A．environmental B．national C．economic D．geographic23．A．locals B．tourists C．visitors D．cleaners24．A．transports B．accommodation C．restaurants D．service25．A．addresses B．paves C．proposes D．receives26．A．separate B．individual C．alternative D．objective27．A．reform B．guidance C．invitation D．support28．A．convincing B．discouraging C．preventing D．resisting29．A．pace B．escape C．withstand D．ease30．A．culture B．knowledge C．entertainment D．ability31．A．take over B．bring up C．come back D．lay off32．A．distinction B．harmony C．association D．comparison33．A．French B．Italian C．Spanish D．German34．A．carry out B．give into C．spread out D．impact on35．A．slight B．complex C．temporary D．sustainable四、阅读选择MTLEDANON ICE CENTER *900 CEDAR BOULEVARD*PITTSBURGH,PA 15228(412)561-4363 WHO: Skaters of all ages and abilities.

Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.“The physics hasn’t changed. It’s about much cleverer design that offers much-needed flexibility in terms of operation,” said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point C in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.The UK, which opened the world’s first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power’s ability to restore confidence.However, the country’s agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country’s future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.39．Which of the following is true about the advanced modular reactors (AMRs)?A．AMRs produce more power than traditional reactorsB．Small in scale, AMRs rose more safety risksC．So far, most AMRs have not been put into use yetD．Governments prefer energy of solar and wind to that of AMRs40．In paragraph 5, the author mentions the plants in Western Europe and the US to ________.A．prove that nuclear power has been threatened by safety concern.B．show that the construction of nuclear power plants cost more that the budget available.C．indicate the construction of nuclear plants are slow in speed.D．point out that most power plants have adopted the latest nuclear technology.41．What can be inferred from the passage?A．Some people have lost confidence in the development of nuclear plantsB．The UK government seeks to reduce the negative impact of nuclear power on its economy.C．The plan to build two power plants in Hinkley Point has been desertedD．a kind costs for small modular reactors would be higher relative to large nuclear reactors.42．Which of the following can serve as the best title of this passage?A．Britain counts on nuclear energy to keep lights onB．Traditional nuclear plants boom with mini reactorsC．Nuclear’s share of p ower generation remain steadD．Nuclear power looks to shrink its way to success五、概要写作43．Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Where are the bees?Bees are essential to the production of food we eat. Bees make honey, but they also pollinate large areas of crops, such as straw berries, apples and onions. About a third of the food we eat is a result of pollination of the bees. Unfortunately, bees have been disappearing at an alarming rate.In 2006, bee keepers started reporting about something called Colony Collapse Disaster (CCD).The main sign of CCD is the loss of adult honey bees from a hive. In October of 2006, some beekeepers reported that they had lost between 30 and 90 percent of their hives.There were many theories for the disappearance of the bees. But the most convincing one has to do with pesticides and lifestyles of bees today. Nowadays, beekeeper get most of their income not from producing honey but from renting bees to pollinate plants. This means that the life of the typical bee now consists of travelling all around the country to pollinate crops as the seasons change. That means a lot of traveling on trucks, which is verystressful to bees. It is not unusual for up to 30% of the hive to die during transport due to stress. In addition, bees that spend most of their time locked up on trucks are not exposed to what they usually live on. Instead, they live on a sweet liquid from corn, usually polluted with pesticides.The exact reason for the disappearance of bees is not sure, but losing bees is very costly to the economy. The bee pollination services are worth over $8 billion a year. With no bees, pollination will have to be done by hand, which would have effects on the quality of food and increased food priced. We hear a lot about big environmental disasters almost every day. But one of the biggest may just be the less of that tiny flying insect._____________________________________________________________________________________________ _____________________________________________________________________________________________ _____________________________________________________________________________________________ _________________________________________________________________________________________六、汉译英（整句）Translation: Translate the following sentences into English, using the words given in the brackets.44．究竟是什么激发小王学习电子工程的积极性？(motivate)45．网上支付方便了客户，但是牺牲了他们的隐私。

高考冲关第16练

高考冲关第16练一、阅读下面的文字，完成1～4题。

这只摇了38年的轮椅，停了史铁生总梦想自己是一个田径运动员，最好有“一米九以上的身材”，并且跑起百米来不超过“九秒九几”。

他最爱看的电视节目是田径比赛，他甚至能说出“所有田径项目的世界纪录”。

但因为瘫痪，这个病人已经在轮椅上度过了整整38年。

2010年12月31日，因为突发脑溢血，史铁生带着永不能实现的梦想和未完成的书稿，离开了这个世界。

这个一直自嘲“职业是生病，业余在写作”的男人，终于“辞职”了。

从21岁那年开始，史铁生就一直没有逃过病痛的折磨。

他把身体比喻成一架飞机，先是作为“起落架”的两条腿瘫痪了，然后像是“发动机”般的两个肾也“一起失灵”，患上了尿毒症。

他不得不每周接受三次透析，全身的血液先被抽出来，再被输回去。

评论人潘采夫记得，2005年，他前去接史铁生参加一个活动，看见他“那么瘦弱”，就提出要把他抱进车里。

但这个提议却被拒绝了。

直到现在，潘采夫仍然记得这个作家“努力地抓着把手，靠臂力把自己一点点挪进车座”的样子。

可是，在朋友们的眼里，史铁生乐观得“根本不像一个被重病缠绕的病人”。

几乎所有采访过他的人都提到，他很少一脸愁容，恰恰相反，他“太爱笑了”，黑镜框后的“小眼睛眯成一条缝，有时还透着几分孩子般的狡猾”。

当然，并非从一开始，这个病人就能笑着面对他无法摆脱的梦魇。

21岁时，他“活到最狂妄的年龄上忽地残废了双腿”。

朋友们还记得，那时，如果有人嘲笑他的腿，“他恨得想抱着炸药包冲过去”。

这个年轻的病人最常去活动的地方，是离大杂院不远的地坛。

在这座荒废的园子里，“一连几个小时专心致志地想关于死的事，也以同样的耐心和方式想过为什么要出生”。

最终，这个古园里诞生了一篇15 000字的《我与地坛》。

这部探讨生与死、荒废与生长、绝望与希望的长篇散文，打动了无数读者，以至于作家韩少功评价道，“《我与地坛》这篇文章的发表……对当年的文坛来说，即使没有其他的作品，那一年的文坛也是一个丰年”。

2021高考地理一轮复习课时冲关：第十六章第2讲产业转移—以东亚为例

第2讲产业转移——以东亚为例测控导航考点题号产业转移的影响因素1、3、4、6、7、9、12、13 产业转移对区域发展的影响2、5、8、10、11、12、13 一、选择题(2019·贵州凯里模拟)全球制造业发展出现过三次较大规模的转移,目前正发生第四次转移。

下图示意全球制造业转移路径。

据此回答1~2题:1.从转移路径看,影响全球制造业转移的主导因素是()A.劳动力成本B.自然资源C.工业基础D.技术水平2.在全球制造业第四次转移的背景下,我国制造业的发展战略是()A.加大政策的支持,吸引制造企业回归B.扩大生产规模,保持价格优势C.进口东南亚等国产品,替代国内生产D.加强技术研发,培育竞争优势解析:1.A 2.D第1题,据图分析可知,全球制造业的转移是一个不断追逐低劳动力成本的过程,随着全球制造业主要承担国家人口红利的逐渐消失,人力成本不断上升,制造业就会寻求新的低成本区域。

因此,影响全球制造业转移的主导因素是劳动力成本,A项正确。

第2题,目前全球制造业主要向东南亚等新兴经济体转移,说明我国劳动力价格上涨,同时市场饱和,技术优势不明显,因此我国制造业不应再依赖劳动力优势,而应加大对科技的投入,树立自己的品牌,增强市场竞争力,D项正确。

(2019·四川乐山调研)技术经济水平梯度差异的两个地区按互补性原则,一个地区内失去比较优势的产业会转往具有比较优势的地区。

高考冲关第15练

一、(2012·北京高考)阅读下面的作品，完成1～4题。

心灵的篝火张海迪我写这部长篇时很多次都在想，人们最好在下个千年翻看这部小说。

我不是什么预言者，但我坚信，我在这本书里所描述的关于攀登雪山峰顶的一些艰险，到那时也许就不存在了，人们很容易就能登上珠穆朗玛峰——海拔8 848米的山顶上已有了我们的研究站点，如同在南极建立的长城站，珠峰上的站点最好也叫长城站。

不过我也在想，假如8 848米不再是不可逾越的障碍，世界上还有什么高峰要攀登呢？只要地壳不变动，8 848米将是有限的数字和高度，而人类的探索精神则是无限的。

人类总是想超越极限，却又被无数的障碍阻挠，劈开了层峦叠嶂，人也就跨越了千山万水。

打算写这部书时，我总感到有一种无形的束缚，它始终不让我的想象展开翅膀到无边无际的天地里翱翔，可我说不清那紧紧束缚自己的是什么。

我常常被这种困惑搅扰，同时也为超越困惑、获得心灵的解放而不懈地寻找飞往更大空间的方向。

我为此等待了很多年。

有一天，我终于看到了梅里雪山！接下来的很多个夜晚，我都是在网上度过的，我被迷住了。

那里有成百上千条关于梅里雪山的文字介绍，还有很多绮丽的风光图片，于是我看见我的一个主人公回头对我笑了，在此之前，我一直让他在一个不知名的空旷地带徘徊，在本书里他是梅里雪山的攀登者。

梅里雪山主峰卡瓦格博海拔只有6 740米，可它的地理环境却很复杂，山上终年积雪，陡峭的山体，风化的岩石，还有瞬息万变的气候，会让攀登者突然陷入绝境。

卡瓦格博至今还是一座人类未及山顶的处女峰。

只要人们达不到顶峰，它就永远是一个神秘的向往，一个难以超越的存在。

人们可能还记得1991年中日联合登山队攀登梅里雪山的惨剧，十七个登山勇士无一人生还。

为什么鲜活的生命要去荒无人烟的地方，在那里经受暴风雪的袭击，面临雪崩随时发生的危险，陷入人生的绝境？天光黯淡，无边的黑夜，厚厚的积雪，看不见一线星光，周围也没有篝火，不灭的只是心灵的篝火，最后那火也覆盖在冰雪中……当太阳重新照耀时，冰盖上又多了几座新的冰雕，他们的面容都十分安详，好像还在酣睡，却再也醒不过来了……也许在多少年之后，地球进一步演化，它变暖了，冰川坍塌，雪山融化，十七个勇士还会获得新生。

一提到雨，也就必然地要想到雪。“ ① ”自然是江南日暮的雪景。“ ② ”，则雪月梅的冬宵三友，会合在一道，在调戏酒姑娘了。“ ③ ”，是江南雪夜，更深人静后的景况。“ ④ ” 又到了第二天的早晨，和狗一样喜欢弄雪的村童来报告村景了。诗人的诗句，也许不尽是江南所写，而做这几句诗的诗人，也许不尽是江南人，但这几句诗来描写江南的雪景，岂不直截了当，比我这一枝愚劣的笔所写的散文更美丽得多？

[解析] 雪泥鸿爪的意思是鸿雁在雪泥上踏过留下的痕迹，比喻往事遗留下的痕迹。这里强调的是在巨大的武汉的掩映下， “我”个人的渺小，搭配不当。“对于我在一九五七年的加盟，武汉这座巨大的城市”主客颠倒，应该是“对于武汉这座巨大的城市，我在一九五七年的加盟”。
若再要点些景致进去，则门前可以泊一只乌篷小船，茅屋里可以添几个喧哗的酒客；天垂暮了，还可以加一味红黄，在茅屋窗中画上一圈暗示着灯光的月晕。人到了这一个境界，自然会胸襟洒脱起来，终至于得失俱亡，死生不问了。我们总该还记得唐朝那位诗人做的“暮雨潇潇江上村”的一首绝句罢？诗人到此，连对绿林豪客都客气起来了，这不是江南冬景的迷人又是什么？

一、阅读下面的文字，完成1～3题。对于我在一九五七年的加盟，武汉这座巨大的城市，只如一滴水掉入这长江中一样，可谓雪泥鸿爪。但对于我来说，它就几乎塑造了我的生命。我常常会想，这座城市有如一本摊开着的书，长江是它的书脊，南北两岸是它摊开的扉页。而行走的我，穿行在它的街巷中，就仿佛走在它的字里行间一样。我曾经想要努力地去读懂它的每一行文字的内容，努力去参透沉淀在这些文字深处的寓意，努力去看清落在这些字后的阴影，努力去获悉在这些字后的故事。

There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the elegant way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Occasionally, I would read a novel that was assigned, but I didn’t enjoy this type of reading. I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Yet, now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new c haracter. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Rea ding is a vital part of my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.41．Why did the author want to grab the newspaper out of mom’s hands?A．She wanted mom to read the news to her.B．She was anxious to know what had happened.C．She couldn’t wait to tear the newspaper apart.D．She couldn’t help but stop mom from reading.42．According to Paragraph 3, the author’s reading of road signs indicates ________.A．her unique way to locate herselfB．her eagerness to develop her reading abilityC．her effort to remind mom to obey traffic rulesD．her growing desire to know the world around her43．What was the author’s view on factual reading?A．It would help her update test-taking skills.B．It would allow much room for free thinking.C．It would provide true and objective information.D．It would help shape a realistic and serious attitude to life.44．The author takes novel reading as a way to ________.A．explore a fantasy landB．develop a passion for learningC．learn about the adult communityD．get away from a confusing world45．What could be the best title for the passage?A．The Magic of ReadingB．The Pleasure of ReadingC．Growing Up with ReadingD．Reading Makes a Full ManHow does an ecosystem(生态系统) work? What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator(掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked; when a predator lives on various species, theyare weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction(灭绝) of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack.And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists say, because once ecosystems pass their tipping point(临界点), it is remarkably difficult for them to return.46．What have scientists discovered with the help of mathematical models of food webs?A．The living habits of species in food webs.B．The rules governing food webs of the ecosystems.C．The approaches to studying the species in the ecosystems.D．The differences between weak and strong links in food webs.47．A strong link is found between two species when a predator ________.A．has a wide food choiceB．can easily find new preyC．sticks to one prey speciesD．can quickly move to another place48．What will happen if the populations of top predators in a food web greatly decline?A．The prey species they directly attack will die out.B．The species they indirectly attack will turn into top predators.C．The living environment of other species will remain unchanged.D．The populations of other species will experience unexpected changes.49．What conclusion can be drawn from the examples in Paragraph 4?A．Uncontrolled human activities greatly upset ecosystems.B．Rapid economic development threatens animal habitats.C．Species of commercial value dominate other species.D．Industrial activities help keep food webs stable.50．How does an early-warning system help us maintain the ecological balance?A．By getting illegal practices under control.B．By stopping us from killing large predators.C．By bringing the broken-down ecosystems back to normal.D．By signaling the urgent need for taking preventive action.Would you BET on the future of this man? He is 53 years old. Most of his adult life has been a losing struggle against debt and misfortune. A war injury has made his left hand stop functioning, and he has often been in prison. Driven by heaven-knows-what motives, he determines to write a book.The book turns out to be one that has appealed to the world for more than 350 years. That former prisoner was Cervantes, and the book was Don Quixote（《堂吉诃德》）. And the story poses an interesting question: why do some people discover new vitality and creativity to the end of their days, while others go to seed long before?We’ve all known people who run out of steam before they reach life’s halfway mark. I’m not talking about those who fail to get to the top. We can’t all get there. I’m talking about people who have stopped learning on growing because they have adopted the fixed attitudes and opinions that all too often come with passing years.Most of us, in fact, progressively narrow the variety of our lives. We succeed in our field of specialization and then become trapped in it. Nothing surprises us. We lose our sense of wonder. But, if we are willing to learn, the opportunities are everywhere.The things we learn in maturity seldom involve information and skills. We learn to bear with the things we can’t change. We learn to avoid self-pity. We learn that however much we try to please, some people are never going to love us—an idea that troubles at first but is eventually relaxing.With high motivation and enthusiasm, we can keep on learning. Then we will know how important it is to have meaning in our life. However, we can achieve meaning only if we have made a commitment to something larger than our own little egos(自我), whether to loved ones, to fellow humans, to work, or to some moral concept.Many of us equate(视……等同于) “commitment” with such “caring” occupations as teaching and nursing. But doing any ordinary job as well as one can is in itself an admirable commitment. People who work toward such excellence—whether they are driving a truck, or running a store—make the world better just by being the kind of people they are. They’ve learned life’s most valuable lesson.51．The passage starts with the story of Cervantes to show that ________.A．loss of freedom stimulates one’s creativityB．age is not a b arrier to achieving one’s goalC．misery inspires a man to fight against his fateD．disability cannot stop a man’s pursuit of success52．What does the underlined part in Paragraph 3 probably mean?A．End one’s struggle for liberty.B．Waste one’s energy taking risks.C．Miss the opportunity to succeed.D．Lose the interest to continue learning.53．What could be inferred from Paragraph 4？A．Those who dare to try often get themselves trapped.B．Those who tend to think back can hardly go ahead.C．Opportunity favors those with a curious mind.D．Opportunity awaits those with a cautious mind.54．What does the author intend to tell us in Paragraph 5？A．A tough man can tolerate suffering.B．A wise man can live without self-pity.C．A man should try to satisfy people around him.D．A man should learn suitable ways to deal with life.55．What is the author’s purpose in writing the passage？A．To provide guidance on leading a meaningful adult life.B．To stress the need of shouldering responsibilities at work.C．To state the importance of generating motivation for learning.D．To suggest a way of pursuing excellence in our lifelong career.四、阅读表达阅读短文，按照题目要求用英语回答问题。

【解析】选A。

由“那么”可知第二个空应该填“如果”；“需慢慢品味”是一个前提条件，所以第三个空填“才”；“有了这些小巷，江南的小城生动起来”是因果关系，所以第五个空填“因为”或“由于”。

综合分析，可知答案为A。
