D.《三国志演义》的刊刻及流行从侧面反映了明中期文化开放,放松了对通俗文学的管制。
(二)实用类文本阅读(本题共3小题,12分)
阅读下面的文字,完成下面小题。
材料一:
当前,我国的城镇化水平已达到63.9%,城市发展已从过去的增量扩张主导发展阶段逐步转向内涵品质发展阶段。当前,我国人居环境建设领域面临着城市发展规模ቤተ መጻሕፍቲ ባይዱ局与资源生态环境承载能力不相适应,城市发展建设的能耗、资源消耗和碳排总量高,城市安全韧性不足,宜居质量与健康水平不高,交通拥堵,文化保护传承不够,城市的包容性、创新性不足等突出的“城市病”问题,解决这些问题需要有新的方法手段。
明初采用了权力集中和政治高压的两手策略,后来又大兴文字狱,实行文化专制,出版政策仍然沿袭元代,书籍的印刷由官府控制,对通俗文艺禁限极严。到了明中期,情况发生了很大变化。成化年间出现了士大夫私人刻书和官府间相互馈赠所刻图书的现象,这些活动不再受朝廷限制。民间刻书活动开始活跃,通俗文学的整理刊刻也出现了,最直接的证据就是1967年在上海嘉定县一个明代墓穴中发现的成化七年至十四年北京永顺堂刊印的“说唱词话”。据研究,这些刊本是墓主人宣昶妻子的随葬品。宣昶无论其家乡还是任所都距北京有千里之遥,照样能读到北京出版的新书,说明此类书籍流通范围之广。既然成化时期的书商们已经开始注意刊刻通俗文学作品,并且所刊说唱词话《花关索传》就是民间三国故事,如果当时真有一部《三国志演义》的抄本在流传,相信书商们不会不予重视和刊刻的。
小说作品一般都是先有抄本,后有刊本,但《三国志演义》未见抄本传世,海内外现存的30多种明刊本中以嘉靖本为最早,书前有庸愚子蒋大器写于明弘治甲寅仲春的《序》和修髯子张尚德写于嘉靖壬午的《引》。据魏安《〈三国演义〉版本考》论证,上海图书馆所藏残页可能就是刘若愚《酌中志》著录的《三国志通俗演义》,即嘉靖元年修髯子作《引》的原本,也就是人们所说的司礼监本,其他嘉靖本都以它为底本。司礼监本刊行后,又有朝廷都察院刊本和郭勋家刻本。于是,《三国志演义》迅速在社会上传播开来,模仿之作便雨后春笋般涌现出来。

AAsia can boast(吹嘘) that it has some of the best beaches in the world. Sihanoukville, Cambodia is a seaside town located 200km or a four-hour bus ride away from the country’s capital, Phnom Penh. With several beaches and small offshore islands, it is definitely not a place to miss out if you are intending to visit Angkor Wat, as the beaches there are stunning and still unspoiled by mass tourism.Serendipity BeachSerendipity Beach is the most popular beach for the masses, since it is the most accessible beach, being the nearest one from the main town area. There are plenty of bars scattered around the beach, so be prepared for the crazy parties every night.Ochheuteal BeachOchheuteal Beach is located south of Serendipity Beach, and it’s a bit of an improvement from Serendipity Beach itself in terms of the people that go there. Over here, there are bars and pubs, but at night, don’t expect wild parties like at the Serendipity Beach area.Otres BeachAll the way down south, near Moat Peam, lies a hidden gem called Otres Beach. This is where you can get your yoga suit on and practice meditation(冥想). This is the quietest beach in Sihanoukville and it is theleast crowded, with very few parties. If your idea of a beach holiday is just yourself and the sun, sea and sand, this place is for you.Koh RongKoh Rong is an island off Sihanoukville that is covered with beautiful sandy beaches. True relaxation lies at Long Beach, which is located on the other side of the island. Clear water surrounds the beach, and once you get there, you’ll be greeted with fine white sand.Koh Rong doesn’t have any roads, so there are no cars or motorbike rentals—everything is mostly on foot.21. Why is Serendipity Beach the most popular with tourists?A. There are a lot of wild parties.B. It is the nearest beach from the main town area.C. The food and drink are varied.D. It has plenty of cheap bars and pubs.22. Which place may be the best choice for a quiet sun bath?A. Serendipity BeachB. Ochheuteal BeachC. Otres BeachD. Rong Beach23. What is special about the beaches in Cambodia?A. They are less developed and visited.B. They are not easily accessible.C. They are within walking distance to its capital.D. They offer tasty seafood.BIf you find yourself hitting the snooze button (闹钟延时按钮) every morning, don’t blame yourself. Your work schedule could be to blame.Research now shows that, for many of us, our work schedules don’t go with our natural body clocks—and experts are urging employers to take notice. Sleep is a “strategic resource” that most companies are ignoring. When work schedules are aligned with people’s natural sleep patterns, they produce higher quality and more innovative work because they are more focused, less stressed and generally healthier. The opposite is also true—when employees are not getting enough sleep they are more likely to make major mistakes and suffer from workplace injuries.But it’s not just about the amount of sleep you get. It’s important that people recognize every living thing, from primitive bacteria to human beings, has a biologically determined internal body clock. This determines whether you are a night owl (夜猫子), an early bird or somewhere in the middle. We don’t have any choice. “It’s like feet,” said Till Roenneberg, a professor of chronobiology(生物钟学). “Some people are born with big feet and some with small feet, but most people are somewhere in the middle.”Many companies start the workday at 8 a.m. or 9 a.m., putting their work schedules in disagreement with their employees’ body clock. This mismatch, along with the pressure to be productive and be available to respond to email or take calls at all hours of the day and night, means that many people suffer from what is called “social jet lag”.24. The underlined word “aligned” in Paragraph 2 means ______.A. matchedB. cooperatedC. conflictedD. shortened25. What does Till Roenneberg’s remark mean?A. The amount of sleep you get counts much.B. An early bird does better than a night owl.C. We are born to have a body clock.D. Most people have neither too big nor too small feet.26. If people suffer from “social jet lag”, they will ______.A. not be as clever as other peopleB. fail to finish their daily tasksC. fail to adjust their body clockD. act as if they were in the wrong time zone27. What is the best title for the passage?A. Body clock and good work habitsB. Late for work? Maybe not your faultC. How to improve your work efficiencyD. Urgent need to change your body clockCNo doubt that humans have widely changed, developed, and exploited much of the natural world for our own ends. But how much of the land surface remains free of our often-harmful influence?In a new study, scientists compared figures from four different sets of data using different kinds of methods and classification systems to answer this question. On average, the researchers say roughly half (48 to 56 percent) of the world’s land shows “low” influence of humans. While the figures may inspire many—stressing the vast expanse of significantly untouched lands that can still be protected through conservation measures—the study also shows just how much of the Earth has already been occupied and used by humans.In fact, only about a quarter (20 to 34 percent) of the planet’s ice-free land surface shows “very low” signs of human influence, the researchers say, and the parts of the planet that we have left alone up until now constitute(构成) some of the least livable places on Earth. In other words, whether through urbanization, forestry, agriculture or other means, humans have applied the most influence on biodiverse land that presented ripe and easy opportunities for immediate human needs; in contrast, roasting deserts in the world’s hottest places, or frozen wastelands in its coldest spots, have been ignored.Even so, the researchers say the results shown here give us a strong, clear marker that we can use to help structure existing and future conservation efforts by preventing disturbance on existing low influenced areas, meanwhile, recovering areas for conservation in land that has already been exploited too much.“The encouraging takeaway from this study is that if we act quickly and decisively(果断地), there is a slim window in which we can still conserve roughly half of the Earth’s land in a relatively untouched state,” says biologist and lead author of the study, Jason Riggio.There’s a chance, right now, to draw a line in the sand, and say “no more”.28. Why was the new study carried out?A. To find out why humans exploit nature.B. To figure out the land free from human influence.C. To prove humans are harmful to nature.D. To clarify the Earth is not occupied by humans completely.29. Which places are influenced most by humans?A. Woodless lands.B. Ice-free lands.C. Places with biodiversity.D. Places with warmth.30. What can we do based on the research?A. Make use of the unlivable area through different means.B. Remove the influence on the previous disturbed area.C. Attempt to have no bad effect on the “untouched” land.D. Reconstruct the overexploited land with forest and agriculture.31. What’s the writer’s attitude towards the untouched land?A. It should be urbanized immediately.B. It should be covered with plants.C. It should be free from humans and animals.D. It should be undisturbed and preserved.DOn Monday, December 5, online retailing(零售) giant Amazon announced the opening of its first physical store. Called Amazon Go, the Seattle-based store that is currently being tested by company employees, learns from regular grocery stores except for one thing—“Just Walk Out” technology. All purchases are handled electronically, which means there are no cashiers, checkouts or lines. Shoppers simply take what they need and leave.To shop at Amazon Go, customers need to open an Amazon account and download the store’s App onto their smartphones. Upon entering the store, they scan a QR code (二维码) with their phones and begin shopping. Every item picked up gets added to the bill automatically. If the customer changes his/her mind, all he/she has to do is return the purchase back on the shelf, and it will be removed from the final bill. Once the customer leaves the store, the amount spent is automatically taken out from the Amazon account and a digital receipt is generated to remind the shopper of the trade.To provide busy customers a pleasant shopping experience, Amazon, which has been working on this concept for four years, plans to keep the store size at a “comfortable” 1,800 square feet. In addition to typical grocery products like bread and milk, the store will stock ready-to-eat breakfast, lunch and dinner options, made by on-site chefs. There will also be chef-designed Amazon Meal boxes for those who prefer to cook the food at home.After years of joint efforts by Amazon staff, Amazon Go finally opened in 2021. Amazon will not provide any insight into the cutting-edge “Just Walk Out” technology. The company website states, “The checkout-free shopping experience is enabled by the same types of technologies used in self-driving cars: computer vision, sensor fusion and deep learning.”32. What is the advantage of Amazon Go over regular grocery stores?A. Store size.B. Shopping speed.C. Product price.D. Parking convenience.33. What is paragraph 2 mainly about?A. Why to download the store’s App.B. How to open an Amazon account.C. How to shop at Amazon Go.D. What to buy at Amazon Go.34. What can we infer from paragraph 3?A. People can shop and eat at Amazon Go.B. Chefs will offer on-site cooking lessons.C. 1,800 square feet is the best size of grocery stores.D. Amazon spent years improving its service.35. What makes possible the checkout-free shopping experience?A. High-technology products.B. The help of the car industry.C. The deep learning method.D. Teamwork by Amazon staff.第二节(共5小题;每小题2分,满分10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。
