材料一:非虚构文学首先要面对的就是非虚构在文学中的合法性问题,也即“真实"在文学中的合法性问题.就文学而言,“真实”是一个很奇怪的词语。
在通行的文学标准中,“真实”只是最低级的文学形式.韦勒克在《文学理论》中谈到现实主义时认为,“现实主义的理论从根本上讲是一种坏的美学,因为一切艺术都是‘创作',都是一个本身由幻觉和象征形式构成的世界”。
“真实”从来都不是艺术的标准.但是,必须注意到,韦勒克所反对的“现实”和“真实”是就其最基本意义而言的,是指物理意义的现实和真实.“那儿有一朵玫瑰花”,这是物理真实,但这还不是文学。
文学要求比物理真实更多的真实,“那儿是哪儿?庭院、原野、书桌?谁种的,或谁送的?那玫瑰花的颜色、形态、味道是什么样子?”这才进入文学的层面,因为关于这些会是千差万别的叙述。
即使是非虚构写作,也只能说:我在尽最大努力接近“真实”.在“真实”的基础上,寻找一种叙事模式,并最终结构出关于事物本身的不同意头和空间,这是非虚构文学的核心。
非虚构文本并不排斥叙事性,相反,这也是它的必由之路。
上世纪50年代至70年代的美国出现了大量的非虚构作品,“一种依靠故事的技巧和小说家的直觉洞察力去记录当代事件的非虚构文学作品的形式".非虚构文学融合了新闻报道的现实性与细致观察及小说的技巧与道德眼光—-倾向于纪实的形式,倾向于个人的坦白,倾向于调查和暴露公共问题,并且能够把现实材料转化为有意义的艺术结构,着力探索现实的社会问题和道德困境.一个最基本的逻辑是,只有在你声称自己是进行非虚构写作时,你才面临着“是否真实”的质疑,假借“真实”之名,你赢得了读者的基本信任,并因此拥有了阐释权和话语权。

AWelcome to the hands-down Big5game reserve in South Africa.Volunteering in our camp in the African bush is definitely a rewarding and convenient way to help you gain a sense of devotion and satisfaction with no extra material rewards.Why to joinIt's a once-in-a-lifetime experience,where you get to give back to the natural environment and the local community.It not only is an extremely satisfying feeling when you know that you've helped to protect this incredible part of the world for generations to come,but enables you to gain invaluable skills and knowledge in conservation.RequirementsPriority will be given to those candidates with great patience and devotion.Rich experience for wildlife conservation as well as a certificate in wildlife protection is not necessarily important.Refusal goes to animal abusers.What to expectWorking alongside trained forest protectors,conservation staff and other volunteers from Monday to Friday(8: 30a.m.-4:30p.m.),you're expected to help with fence guards to keep animals safe from poachers(偷猎者), feed animals,and even help catch animals for medical treatment.During term-time,you may also work with the local community,delivering meals with nutrition to local children.EntertainmentAfter work,you'll have plenty of time to relax on the reserve.Be bathed in the sun by the reserve's pool,play a few rounds of tennis or relax in the common room with your new friends.The program contains various overnight short-distance journeys in the surrounding areas such as Port Elizabeth,Jeffreys Bay and Grahamstown,where youcan go hiking,windsurfing,whale-watching,horse-riding and much more.1.What will participants acquire in the program?A.Survival skills in wilderness.B.Knowledge of wildlife protection.C.Certificates of animal conservation.D.Experience in community management.2.What should a volunteer do in the camp?A.Give food to animals.B.Keep animals in cages.C.Study diseases of animals.D.Train animals for research.3.What is an advantage of volunteering in the camp?A.Material rewards are plentiful.B.Accommodations are top-class.C.Flexible working hours are allowed.D.Recreational activities are provided.BOver40students with low vision study at a school in Gandhinagar,Gujarat.It was designed by Anand Sonecha,founder of an architecture company.Featuring a bright yellow entrance door,which stands out against the white walls,the school is decorated with a variety of sweet-smelling plants everywhere.Inside the classrooms,the walls feel smooth in contrast to the rough outside of the building.These all help students familiarize themselves with the area straightforwardly,without any trouble.The school provides an open space serving as a platform for the visually-challenged students to play,perform, or celebrate festivals and the students are easy to orient themselves according to the sound,smell,sight and touch.“The idea behind the design was to make the school more accessible to the students,”Sonecha says,“They come from remote villages and towns in Gujarat,and I am eager to help them.”During the construction,Sonecha used contrasting colors so that students could easily distinguish between the elements.Blue was used for all classroom doors,yellow for the entrance gate,black for switch buttons,and yellow and green for the furniture.All these colors contrasted with the white walls of the school,helping the students locate different elements.Different areas are of different height and width,which makes the sounds and noises change according to the echo(回音)produced in these spaces.Furthermore,he cooperated with fellow landscape architect Lokendra Balasaria to plant more than1,000plants of37species.These sweet plants have been grown not only to lead the children to move in the school through smell but also to attract butterflies and birds,and provide shade.“The structure of the building is designed similarly to any other school building,only with a few clever elements.My intention was to avoid making it look distinct from other schools,”Sonecha explains,“I hope that there are no different schools for such students.Instead,all these elements should be added to public spaces for them.And my follow-up efforts may be there.”4.Why did Sonecha design the school in Gandhinagar?A.To explore architecture styles.B.To raise funds for his company.C.To offer convenience to the students.D.To improve students'learning ability.5.What does the underlined word“orient”in Paragraph2mean?A.Relax.B.Waken.C.Cheer.D.Direct.6.How does the school help students perform daily routine?A.By expanding activity areas.B.By stimulating multiple senses.C.By offering behavioral guidelines.D.By strengthening safety measures.7.What will Sonecha probably do in the future?A.Promote accessibility in the public regions.B.Modernize architecture with smart devices.C.Build special schools for disabled students.D.Decorate schools with traditional elements.CLanguage gives us the power to describe countless actions,properties and relations that compose our experiences,real or imagined.As for how languages were created,scientists found iconicity might play a key role. People can't bridge language gap and understand each other without iconicity.When playing a game of charades (猜字谜),we act out our meaning,using our hands and bodies to describe the sizes and shapes of objects.The key to this process of forming new symbols is the use of iconicity.Not limited to gesturing,iconicity appears in our visual communication too.Traffic signs,food packaging,maps...wherever there are people communicating,you will find iconicity.According to our research,iconicity might also exist in our voices.We organized a contest in which we invited contestants to record a set of sounds to express different meanings.The winner of the contest was determined by how well listeners could guess the intended meanings of the sounds based on a set of written options.Critically,the sounds that contestants submitted couldn't include actual words or onomatopoeias(拟声词).Listeners were remarkably good at interpreting the meanings of the sounds.Yet,all of the contestants and listeners were speakers of English.Thus,it was possible that listeners'success relied on some cultural knowledge that they shared with the speakers.Did the listeners also understand the speakers from completely different cultural backgrounds?Later,an Internet survey translated into25different languages was carried out.Participants listened to each sound from the English speakers and guessed the meaning by choosing from six written words.Guessing accuracy for the different groups ranged from74percent for English speakers to34percent for Portuguese speakers.It is far from perfect,but well above the chance rate of eight percent expected by us.Taken together,these studies show that our capacity for iconic communication has played a critical role. Without this special talent,language would likely never have gotten off the ground.8.Which of the following can explain“iconicity”?A.A skill in foreign language learning.B.The process of acting out our meanings.C.The connection between form and meaning.D.A barrier between different language speakers.9.What can we know about the contest?A.It required sounds containing meanings.B.Its winners were creative in recordings.C.It aimed to prove iconicity in words.D.Its entries were familiar to listeners.10.What can be inferred from Paragraph4?A.English pronunciations differ.B.The research has a limitation.C.The cultural gap is narrowing.D.Listening skills vary in cultures.11.What is the significance of the research?A.Clarifying the influence of sounds.B.Proving the necessity of exchanges.C.Uncovering the origin of languages.D.Identifying the function of gestures.DMany of us remember the feeling of having our braces(牙套)regularly adjusted and retightened at the dentist's.And interventions are based entirely upon the estimate of dentists and involve a great deal of trial and error,which can lead to too many visits to the dentist's.Professor Erleben and his team created a computer model that creates accurate3D simulations(模拟)of an individual patient's jaw,which dentists can use to predict how sets of braces should be designed to best straighten a patient's teeth and plan the best possible treatment.To create these simulations,the computer model was used to map sets of human teeth after getting detailed CT images of teeth and the small,fine structures between the jawbone and the teeth.This type of precise digital simulation is referred to as a digital twin,a virtual model that lives in the cloud.The virtual model can answer what's happening in the real world,and do so instantly.For example,one can ask what would happen if you pushed on one tooth and get answers with regards to where it would move and how it would affect other teeth.The model also helps to predict the post treatment effect,achieve“visualization”of treatment,and facilitate patients to understand the plan of straightening their teeth.What's more,it has enabled more flexible and convenient digital medical follow-up services.The area of research that uses digital twins is relatively new.“However,we need to set up a sufficiently big database if digital twins are to really take root and benefit the healthcare industry,”Erleben said,“In the future,the virtual model can be used to plan,design and improve,and can therefore be used to operate companies,robots, factories and used much more in the energy,healthcare and other fields.”12.What is Paragraph1mainly about?A.The professional integrity of dentists.B.The current state of dental treatment.C.The procedure of retightening braces.D.The intervention of modern technology.13.Which was the first step in creating3D simulations?A.Predicting treatment effect.B.Designing a computer model.C.Drawing the shape of a mouth.D.Obtaining the details of teeth.14.What is Professor Erleben's attitude towards digital twins?A.Doubtful.B.Curious.C.Favorable.D.Dismissive.15.What can be a suitable title for the text?A.Why digital twins make a hitB.Where virtual treatment goesC.What trouble dentists encounterD.How a virtual model aids dentists第二节(共5小题;每小题2.5分,满分12.5分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,18分)阅读下面的文字,完成1~5题。
“从胸臆中流出”的性灵诗风至少有两个弊端,一是诗行一气直下,容易产生“滑俗”之弊;二是浅近,缺乏含蓄蕴藉的韵味。
对此,姚鼐有清楚的认识。
姚鼐虽未直接点名批评袁枚,实亦流露出不满。
他评白诗云:“香山以流易之体,极富瞻之思,非独俗士夺魄,亦使胜流倾心。
然滑俗之病,遂至滥恶,后皆以太傅为藉口矣。
”袁枚在六十岁生日诗中就有“想为香山作后身”之句,所以姚鼐所指后世“滑俗”之病,无疑是针对性灵诗风的弊端。
姚鼐明确指出,“欲作古贤辞,先弃凡俗语”,他批评其时两大诗派“浅易询灶妪,险怪趋虬户”,以“浅易”和“险怪”直指袁枚与厉鹗之失。
性灵诗派外,王士禛及其追随者追求神韵,然格局狭小,骨力不张,滑落为诗坛边缘性存在;宗宋诗风另一趋势是朝俚俗化方向发展,又暴露出“刻露之病”,缺少含蓄之韵味。
对于诗坛的流弊,如何力挽颓波?姚门弟子梅曾亮评其师之诗云:“以山谷之高奇,兼唐贤之蕴藉。
”桐城后学吴汝纶亦云:“先生诗勿问何体,罔不深古雅健,耐人寻绎。
”“山谷之高奇”与“深古雅健”是宋诗风格,“蕴藉”与“耐人寻绎”是唐诗含蓄蕴藉的传统,二者的结合,即“镕铸唐宋”。
姚鼐对于矫正香山“流易”之病的诗人都甚为看重,如选李商隐诗一卷,就是因为其诗“近掩刘白”。
尽管“矫敝流易”时“用思太过,而僻晦之敝又生”,但仍谓之为“诗中豪杰士”。
苏轼之诗,“用梦得、香山格调,其妙处岂刘白所能望哉”。
但因其为“天才”,常人难学,故非理想的典范。

材料一:当前,公众对文化的需求已经从“缺不缺、够不够”升级为“好不好、精不精”。
目前,我们的现代公共文化服务供给与这些新需求之间还存在一定距离。
比如,受经济社会发展水平制约,城乡之间、区域之间的公共文化服务发展水平还存在较大差距;公共文化产品和服务品质还有待提升;改革创新力度有待加强;社会力量的作用尚未充分发挥;数字化、网络化、智能化建设与其他领域相比仍显滞后等。
推进现代公共文化服务高质量发展,必须要应变局、育先机、开断局。
坚持正确导向,是现代公共文化服务高质量发展的根本保障。
高质量发展现代公共文化服务,要坚持党对公共文化工作的领导,牢牢把握社会主义先进文化前进方向,以社会主义核心价值观为引领,从而实现满足人民文化需求和增强人民精神力量相统一,让人民享有更加充实、更为丰富、更高质量的精神文化生活。
高质量发展现代公共文化服务,还要坚持唯美唯善的审美导向。
优质、完善、富有个性和审美的公共文化服务体系,能够吸引广大人民群众参与其中,沉浸式感受文化的力量,全方位提升人民生活品质。
要全力打造新型公共文化空间场景,注重以“人”为中心的参与和体验感,提升公共文化空间品质,涵养人民群众的人文情怀,增强公共文化服务效能。
坚持以人民为中心,提高公共文化服务覆盖面和实效性。
加快推进城乡公共文化服务体系一体建设,推动公共文化数字化建设,创新实施文化惠民工程,提升基本公共文化服务标准化均等化水平,更好保障人民基本文化权益。
