Section I Use of EnglishDirections:Read the following text.Choose the best word(s)for each numbered blank and mark A,B,C or D on the ANSWER SHEET.(10 points)Here's a common scenario that any number of entrepreneurs face today ：you're the CEO of a small business,and though you're making a nice 1,you need to find a way to take it to the next level.What you need to do is 2 growth by establishing a growth team.A growth team is made up of members from different departments within your company,and it harnesses the power of collaboration to focus 3 on finding ways to grow.Let's look at a real-world 4.Prior to forming a growth team,the software company BitTorrent had 50 employees working in the 5 departments of engineering,marketing and product development.This brought them good results until 2012,when their growth plateaued.The 6 was that too many customers were using the basic,free version of their product.And 7 improvements to the premium,paid version,few people were making the upgrade.Things changed,8,when an innovative project-marketing manager came aboard,9 a growth team and sparked the kind of 10 perspective they needed.By looking at engineering issues from a marketing point of view,it became clear that the 11 of upgrades wasn't due to a quality issue.Most customers were simply unaware of the premium version and what it offered.Armed with this 12,the marketing and engineering teams joined forces to raise awareness by prominently 13 the premium version to users of the free version 14,upgrades skyrocketed,and revenue increased by 92 percent.But in order for your growth team to succeed,it needs to have a strong leader.It needs someone who can 15 the interdisciplinary team and keep them on course for improvement.This leader will 16 the target area,set clear goals and establish a time frame for the 17 of these goals.The growth leader is also 18 for keeping the team focused on moving forward and steering them clear of distractions.19 attractive new ideas can be distracting,the team leader must recognize when these ideas don't 20 the current goal and need to be put on the back burner.1.[A]purchase[B]profit[C]connection[D]bet2．[A]define[B]predict[C]prioritize[D]appreciate3．[A]exclusively[B]temporarily[C]potentially[D]initially4．[A]experiment[B]proposal[C]debate[D]example5．[A]identical[B]marginal[C]provisional[D]traditional6．[A]rumor[B]secret[C]myth[D]problem7．[A]despite[B]unlike[C]through[D]besides8．[A]moreover[B]however[C]therefore[D]again9．[A]inspected[B]created[C]expanded[D]reformed10．[A]cultural[B]objective[C]fresh[D]personal11．[A]end[B]burden[C]lack[D]decrease12．[A]policy[B]suggestion[C]purpose[D]insight13．[A]contributing[B]allocating[C]promoting[D]transferring

texts.Answer the questions below each text by choosing A,B,C or D.Mark your answers on the ANSWER SHEET.(40points)Text1In the quest for the perfect lawn,homeowners across the country are taking a shortcut-and it is the environment that is paying the price.About eight million square metres of plastic grass is sold each year but opposition has now spread to the highest gardening circles.The Chelsea Flower Show has banned fake grass from this year's event,declaring it to be not part of its ethos.The Royal Horticultural Society(RHS),which runs the annual show in west London,says it has introduced the ban because of the damage plastic grass does to the environment and biodiversity.Ed Horne,of the RHS,said:“We launched our sustainability strategy last year and fake grass is just not in line with our ethos and views on plastic.We recommend using real grass because of its environmental benefits,which include supporting wildlife,alleviating flooding and cooling the environment.”The RHS's decision comes as campaigners try to raise awareness of theproblems fake grass causes.A Twitter account,which claims to“cut through the green-wash”of artificial grass,already has more than 20,000followers.It is trying to encourage people to sign two petitions,one callingfor a ban on the sale of plastic grass and another calling for an“ecologicaldamage”tax on such lawns.They have gathered 7,276 and 11,282signaturesHowever,supporters of fake grass point out that there is also anenvironmental impact with natural lawns,which need mowing andtherefore usually consume electricity or petrol.The industry also pointsout that real grass requires considerable amounts of water,weed killer orother treatments and that people who lay fake grass tend to use theirgarden more.The industry also claims that people who lay fake grassspend an average of£500 on trees or shrubs for their garden,whichprovides habitat for insects.In response to another petition last year about banning fake lawns,which gathered 30,000 signatures,the government responded that it has“no plans to ban the use of artificial grass.It added:"We prefer to help people and organizations make the right choice rather than legislating on such matters,However the use of artificial grass must comply with the legal and policy safeguards in place to protect biodiversity and ensure sustainable drainage,while measures such as the strengthened biodiversity duty should serve to encourage public authorities to consider sustainable alternatives.”21.The RHS thinks that plastic grass________.[A]is harmful to the environment[B]is a hot topic in gardening circles[C]is overpraised in the annual show[D]is ruining the view of west London22.The petitions mentioned in Paragraph 3 reveal the campaigners’________.[A]disappointment with the RHS[B]resistance to fake grass use[C]anger over the proposed tax[D]concern about real grass supply23.In Paragraph 4,supporters of fake grass point out________.[A]the necessity to lower the costs of fake grass[B]the disadvantages of growing real grass[C]the way to take care of artificial lawns[D]the challenges of insect habitat protection24.What would the government do with regard to artificial grass?[A]Urge legislation to restrict its use.[B]Take measures to guarantee its quality.[C]Remind its users to obey existing rules[D]Replace it with sustainable alternatives.25.It can be learned from the text that fake grass______.[A]is being improved continuously[B]has seen a market share decline[C]is becoming increasingly affordable[D]has been a controversial productText2It's easy to dismiss as absurd the federal government's ideas for plugging the chronic funding gap of our national parks.Can anyone really think it's a good idea to allow Amazon deliveries to your tent in Yosemite or food trucks to line up under the redwood trees at Sequoia National Park?But the government is right about one thing:U.S.national parks are in crisis.Collectively,they have a maintenance backlog of more than$12 billion.Roads,trails,restrooms,visitor centers and other infrastructure are crumbling.But privatizing and commercializing the campgrounds would not be a cure-all.Campgrounds are a tiny portion of the overall infrastructure backlog,and businesses in the parks hand over,on average,only about 5%of their revenues to the National Park Service.Moreover,increased privatization would certainly undercut one of the major reasons why 300 million visitors come to the parks each year:to enjoy nature and get a break from the commercial drumbeat that overwhelms daily life.The real problem is that the parks have been chronically starved of funding.An economic survey of 700U.S.taxpayers found that people would be willing to pay a significant amount of money to make sure the parks and their programs are kept intact.Some 81%of respondents said they would be willing to pay additional taxes for the next 10 years to avoid any cuts to the national parks.The national parks provide great value to U.S.residents both as places to escape and as symbols of nature.On top of this,they produce value from their extensive educational programs,their positive impact on the climate through carbon sequestration,their contribution to our cultural and artistic life,and of course through tourism.The parks also help keep America's past alive,working with thousands of local jurisdictions around the country to protect historical sites and to bring the stories of these places to life.The parks do all this on a shoestring.Congress allocates only＄3billion a year to the national park system-an amount that has been flat since 2001(in inflation-adjusted dollars)with the exception of a onetime boost in 2009.Meanwhile,the number of annual visitors has increased by more than50%since 1980,and now stands a t330 million visitors per year. 26.what problem are U.S.national parks facedwith?[A]Decline of business profits[B]Inadequate commercialization[C]Lack of transportation services[D]poorly maintained infrastructure27.Increased privatization of the campgroundsmay________.[A]spoil visitor experience[B]help preserve nature[C]bring operational pressure[D]boost visits to parks28.According to paragraph 5 most respondents in the surveywould[A]go to the national parks on a regular basis[B]advocate a bigger budget for the national parks[C]agree to pay extra for the national parks[D]support the national parks'receive reformsText3The Internet may be changing merely what we remember,not our capacity to do so,suggests Columbia University psychology professor Betsy Sparrow.In 2011,Sparrow led a study in which participants were asked to record 40 factoids in a computer(“an ostrich's eye is bigger than its brain,”for example).Half of the participants were told the information would be erased,while the other half were told it would be saved.Guess what?The latter group made no effort to recall the information when quizzed on it later,because they knew they could find it on their computers.In the same study,a group was asked to remember both the information and the folders it was stored in.They didn't remember the information,but they remembered how to find the folders.In other words,human memory is not deteriorating but“adopting to new communications technology,”Sparrow says.In a very practical way,the Internet is becoming an external hard drive for our memories,a process known as“cognitiveoffloading.”Traditionally,this role was fulfilled by data banks,libraries,and other humans.Your father may never remember birthdays because your mother does,for instance.Some worry that this is having a destructive effect on society,but Sparrow sees an upside.Perhaps,she suggests,the trend will change our approach to learning from a focus on individual facts and memorization to an emphasis on more conceptual thinking something that is not available on the Internet.“I personally have never seen all that much intellectual value in memorizing things,”Sparrow says,adding that we haven’t lost our ability to do it.Still other experts say it’s too soon to understand how the Internet affects our brains.There is no experimental evidence showing that it interferes with our ability to focus,for instance,wrote psychologists Christopher Chabris and Daniel.J.Simons.And surfing the web exercisedthe brain more than reading did among computer-savvy older adults in a 2008 study involving 24 participants at the Semel Institute for Neuroscience and Human Behavior at the University of California,Los Angeles.“There may be costs associated with our increased reliance on the Internet,but I’d have to imagine that overall the benefits are going to outweigh those costs,”observes psychology professor Benjamin Storm.“It seems pretty clear that memory is changing,but is it changing for the better?At this point,we don't know.”31.Sparrow’s study shows that with the Internet,the human brainwill________.[A]analyze information in detail[B]collect information efficiently[C]switch its focus of memory[D]extend its memory duration32.The process of“cognitive offloading”________.[A]helps us identify false information[B]keeps our memory from failing[C]Enables us to classify trivial facts[D]lessens our memory burdens33.Which of the following would Sparrow support about theInternet?[A]It may reform our learning approach[B]It may impact our society negatively[C]It may enhance our adaptability to technology[D]It may interfere with our conceptual thinking34.It is indicated in Paragraph 3 that how the Internet affects our brains[A]requires further academic research[B]is most studied in older adults[C]is reflected in our reading speed[D]depends on our web-surfing habits35.Neither Sparrow nor Storm would agree that________.[A]our reliance on the Internet will be costly[B]the Internet is weakening our memory[C]memory exercise is a must for our brains[D]our ability to focus declines with ageText436.According to Paragraph,children growing into adolescence tend to[A]develop opposite personality traits[B]see the word in an unreasonable way[C]have fond memories of their past[D]show affection for their parents37.It can be learned from 2 that Crone'sstudy________.[A]explores teenagers'socialresponsibilities[B]examines teenagers'emotionalproblems[C]provides a new insight intoadolescence[D]highlights negative adolescentbehavior38.What does crone's study find about prosocialbehavior?[A]It results from the wish to cooperate[B]It is cultivated through education[C]It is subject to family influence[D]It tends to peak in adolescence39.It can be learned from the last two paragraphs that teenagers________.[A]over-stress their influence on others[B]care a lot about social recognition[C]Become anxious about their future[D]Endeavor to live a joyful life40.What is the text mainly about________.[A]Why teenagers are self-contradictory.[B]Why teenagers arerisk-sensitive.[C]How teenagers develop prosociality.[D]How teenagers become independent.Part BDirections:Read the following text and match each of the numbered items in the left column to its corresponding information in the right column.There are two extra choices in the right column.Mark your answers on the ANSWER SHEET.(10points)Net-zero rules set to send cost of new homes and extensionssoaringNew building regulations aimed at improving energy efficiency are set to increase the price of new homes,as well as those of extensions and loft conversions on existing ones.The rules,which came into effect on Wednesday in England,are part of government plans to reduce the UK's carbon emissions to net zero by 2050.They set new standards for ventilation,energy efficiency and heating,and state that new residential buildings must have charging points for electric vehicles.The moves are the most significant change to building regulations in years,and industry experts say they will inevitably lead to higher prices at a time when a shortage of materials and high labour costs are already driving up bills.Brian Berry,chief executive of the Federation of MasterBuilders,saysthe measures will require new materials,testing methods,products and systems to be installed.“All this comes at an increased cost during a time when prices are already sky high.Inevitably,consumers will have to pay more,"he says.Gareth Belsham,of surveyors Naismiths,says people who are upgrading,or extending their home,will be directly affected.“The biggest changes relate to heating and insulation,”he explains.“There are new rules concerning the amount of glazing used in extensions,and any new windows or doors must be highly insulated.”Windows and doors will have to adhere to higher standards,while there are new limits on the amount of glazing you can have to reduce unwanted heat from the sun.Thomas Goodman,of MyJobQuote,says this will bring in newrestrictions for extensions.“Glazing on windows,doors and rooflightsmust cover no more than 25%of the floor area to prevent heat loss,"hesays.As the rules came into effect last Wednesday,property developerswere rushing to file plans just before the deadline.Any plans submittedbefore that date are considered to be under the previous rules,and can goahead as long as work starts before 15 June next year.Builders which have costed projects,but have not filed thepaperwork,may need to go back and submit fresh estimates,says MarcusJefford of Build Aviator.Materials prices are already up 25%in the last two years.How much overall prices will increase as a result of the rule changes is notclear."Whilst admirable in their intentions,they will add to the cost ofhousebuilding at a time when many already feel that they are priced out ofhomeownership,"says Jonathan Rolande of the National Association ofProperty Buyers.“An average extension will probably see around£3,000additional cost thanks to the new regs."John Kelly,a construction lawyer at Freeths law firm,believes priceswill eventually come down.But not in the immediate future."As themarketplace adapts to the new requirements,and the technologies thatsupport them,the scaling up of these technologies will eventually bringcosts down,but in the short term,we will all have to pay the price of the necessary transition.”he says.However,the long-term effects of the changes will be more comfortable and energy-efficient homes,adds Andrew Mellor,of PRP architects.“Homeowners will probably recoup that cost over time in energy bill savings.It will obviously be very volatile at the moment,but they will46.Directions:Translate the following text into Chinese.Write your translation on on the ANSWER SHEET.(15points)In the late 18th century,William Wordsworth became famous for his poems about nature.And he was one of the founders of a movement called Romanticism,which celebrated the wonders of the natural world.Poetry is powerful.Its energy and rhythm can capture a reader,transport them to another world and make them see things differently.Through carefully selected words and phrases,poems can bedramatic,funny,beautiful,moving and inspiring.No one knows for sure when poetry began but it has been around for thousands of years,even before people could write.It was a way to tell stories and

understanding them too,because the rhythm and sounds of the words become clearer.

材料一：搞好调查研究，一定要从群众中来、到群众中去，广泛听取群众意见。

人民群众的社会实践，是获得正确认识的源泉，也是检验和深化我们认识的根本所在。

调查研究成果的质量如何，形成的意见正确与否，最终都要由人民群众的实践来检验。

毛泽东同志 1930 年在寻乌县调查时，直接与各界群众开调查会，掌握了大量第一手材料，诸如该县各类物产的产量、价格，县城各业人员数量、比例，各商铺经营品种、收入，各地农民分了多少土地、收入怎样，各类人群的政治态度，等等，都弄得一清二楚。

这种深入、唯实的作风值得我们学习。

领导干部进行调查研究，要放下架子、扑下身子，深入田间地头和厂矿车间，同群众一起讨论问题，倾听他们的呼声，体察他们的情绪，感受他们的疾苦，总结他们的经验，吸取他们的智慧。

既要听群众的顺耳话，也要听群众的逆耳言；既要让群众反映情况，也要请群众提出意见。

尤其对群众最盼、最急、最忧、最怨的问题更要主动调研，抓住不放。

这样才能真正听到实话、察到实情、获得真知、收到实效。

调查研究必须坚持实事求是的原则，树立求真务实的作风，具有追求真理、修正错误的勇气。

现在有的干部善于察言观色，准备了几个口袋，揣摩上面或领导的意图来提供材料。

很显然，这样的调查是看不到实情、得不到真知、做不出正确结论的。

第Ⅰ卷阅读题一、现代文阅读（35分）（一）论述类文本阅读（本题共3小题，9分）阅读下面的文字，完成1~3题。

青花瓷发展的黄金时代是明朝永乐、宣德时期，与郑和下西洋在时间上重合，这不能不使我们思考：航海与瓷器同时达到鼎盛，仅仅是历史的偶然吗？从历史事实来看，郑和下西洋为青花瓷的迅速崛起提供了历史契机。

近三十年的航海历程推动了作为商品的青花瓷大量生产与外销，不仅促进技术创新，使青花瓷达到瓷器新工艺的顶峰，而且改变了中国瓷器发展的走向，带来了人们审美观念的更新。

这也就意味着，如果没有郑和远航带来活跃的对外贸易，青花瓷也许会像在元代一样，只是中国瓷器的诸多品种之一，而不会成为主流，更不会成为中国瓷器的代表。

由此可见，青花瓷崛起是郑和航海时代技术创新与文化交融的硕果，中外交往的繁盛在推动文明大交融的同时，也推动了生产技术与文化艺术的创新发展。

作为中外文明交融的结晶，青花瓷真正成为中国瓷器的主流，则是因为成化年间原料本土化带来了民窑青花瓷的崛起。

民窑遍地开花，进入商业化模式之后，几乎形成了青花瓷一统天下的局面。

一种海外流行的时尚由此成为中国本土的时尚，中国传统的人物、花鸟、山水，与外来的伊斯兰风格融为一体，青花瓷成为中国瓷器的代表，进而走向世界，最终万里同风，成为世界时尚。

一般来说，一个时代有一个时代的文化，而时尚兴盛则是社会快速变化的标志。

因此，瓷器的演变之所以引人注目，还在于它与中国传统社会从单一向多元社会的转型同步。

第I卷阅读题甲必考题―、现代文阅读〔9分．每题3分〕阅读下面的文宇，完成13題．艺术品的接受在过去并不被看作是重要的美学问題，20世纪解释学兴起，一个名为“接受美学〞的美学分支应运而生，于是研究艺术品的接受成为艺术美学中的显学。

过去，通常只是从艺术家的立场出发，发觉将创作看作艺术家审美经验的结晶过程，作品完成绩意味着创作完成。

而从接受美学的角度来看，这一完成并不说明创作已经终结。

它只说明创作的第—阶段告一段落，接下来是读者或现众、听众的再创作。

由于未被阅读的作品的价值包含审美价值仅仅是一种可能的存在，只有通过阅读，它才转化为现实的存在，因此对作品的接受具有艺术本体的意义，也就是说，接受者也是艺术创作的主体之一。

艺术文本即作品对于接受者来说具有什么意义呢？接受美学的创始人、德国的伊瑟尔说艺术文本是一个“召唤结构〞，因为文本有“空白〞“空缺〞“否认〞三个要素。

所谓“空白〞是说它有一些东西没有表达出来，作者有意不写或不明写，要接受者用自己的生活经验与想象去补充；所谓“空缺〞，是言语结构造成的各个图像间的空白，接受者在阅读文本时要把一个个句子表现的图像片断连接起来，整合成一个有机的图像系统；所谓“否认〞指文本对接受者生活的现实具有否认的功能，它能引导接受者对现实进行反思和批判，由此可见，文本的召唤性需要接受者照顾和配合，完成艺术品的第二次创作，正如中国古典美学中的含蓄与简洁，其有限的文字常常引发出读者脑海中的丰富意象。

接受者作为主体，他对文本的接受不是被动的，海德格尔提出“前理解〞，即理解前的心理文化结构，这种结构影响着理解。

理解不可能是文本意义的重现，而只能是文本与“前理解〞的统一，这样，文本与接受就呈现出一种相互作用的关系：一方面文本在相当程度上规定了接受者理解的范围、方向，让理解朝它的本义靠拢；另一方面，文本不可能将接受者完全制约住、标准住，接受者必定会按照自己的方法去理解作品，于是不可防止地就会出现误读或制造。

It was just after sunrise on June morning. ‘’Nicolo,’’whose real name cannot be exposed to the public because of Italy’s privacy laws, finished working the whole night at a factory in Turin. As he often did,he stopped by the “after work auction（拍卖）”run by the Italian police where things found on the trains were sold to the highest bidder. There,among many other things,Nicolo spotted two paintings he thought would look nice above his dining room table. Nicolo and another bidder battled until Nicolo finally won the paintings for $32.When Nicolo retired and went to live in Sicily, he brought the paintings with him. He hung them above the same table he had moved from Turin. His son,age 15, who had taken an art appreciation class, thought that there was something unusual about the one with a young girl sitting on a garden chair. It was signed（签名）”Bonnato” or so he thought,but when he researchedIt, he only found ”Bonnard,” a French painter he had never heard of. He bought a book and was surprised to find a picture of the artist Pierre Bonnard sitting on the same chair in the same garden as his father’s painting.“That’s the garden in our picture,” Nicolo’s son told his father. They eventually learned that the painting they owned was called “The Girl with Two Chairs.” They studied the other painting and learned that it was actually Paul Gauguin’s＂Still Life of Fruit on a Table with a Small Dog.”The family called the Italian Culture Ministry; the official confirmed that the paintings were originals and worth as much as ＄50 million.一度开发之语法填空It was just after sunrise on June morning. ‘’Nicolo,’’ 1 real name cannot be exposed to the public because 2 Italy＇s privacy laws，finished 3 ( work) the whole night at a factory in Turin.
