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。
隋废九品中正,设进士、明经二科取士。
唐承隋制,并增设明法、明字、明算诸科,而以进士、明经二科为主。
进士科重文辞,明经科重经术。
唐高宗、武则天以后,进士科最为社会所重,参加进士科考试被认为是致身通显的重要途径。
进士科以考诗赋为主,此外还考时务策等。
唐代取士由地方举送中央考试,称为乡贡。
被举送应试的人通称为举人。
唐人常说“举进士”,例如韩愈《讳辩》说“愈与李贺书,劝贺举进士”,意思是应举参加进士科的考试,这种人在唐代就称为进士。
韩愈《送孟秀才序》说“京师之进士以千数,其人靡所不有”,就是指当时应举参加进士科考试的人说的。
唐初设有秀才科,不久即废,但是唐人后来仍通称应进士科考试的人为秀才。
唐代中央主持科举考试的机关是礼部,考官通常由礼部侍郎担任,称为知贡举。
唐人进士及第第一名称为状头或状元。
同榜的人在长安慈恩寺雁塔题名,称为题名会。

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。
2018年2月,金庸先生的《射雕英雄传》英文版三部曲(《射雕英雄传》《神雕侠侣》《倚天屠龙记》)将分九卷陆续出版,这是中国优秀传统文化走向世界的又一大事。
中国人有“侠”情,且认为“侠”可以超越文化边界。
西方文化中亚瑟王的圆桌骑士、罗宾汉式的绿林英雄,以及风靡当下的银幕上的超级英雄,在我国都有“侠”缘。
但是,侠不是骑士,甚至不是武士。
不管是骑士,还是武士,都是某种权威——一往往是封建领主给予的一种身份。
而侠,非身份,亦非职业。
侠,其实是一种态度、一种行事方式。
司马迁在《游侠列传》中说,侠,“其行虽不轨于正义,然其言必信,其行必果,已诺必诚,不爱其躯,赴士之困厄。
既已存亡死生矣,而不矜其能,羞伐其德,盖亦有足多者焉。
”太史公的看法,其实太过理想主义。
在笔者看来,侠不见得真有如此伟大,反倒是韩非子的话更为直接,“俠以武犯禁”。
侠,是一种无视“禁忌”的——“禁忌”有好有坏,这种“无視”也自然是双刃剑,是一种直接、狂放的行事方式。
侠讲究的是豪放不羁、快意恩仇。
这种“豪放不羁”,如《笑傲江湖》所描绘的,不贪高位,不惧追杀、不恋亲情,只愿与知己合奏一曲《广陵散》。
侠的“快意思仇”,如王家卫电影《东邪西毒》中的洪七,他收了贫女一个鸡蛋后,冲入王府杀了一众刀客,为贫女的弟弟报了仇,自己则在交战中被削掉一个手指。

AIt looks like 2017 is shaping up to be a record-breaking year in movie History. Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date: 3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading the cast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date: 3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7. Fans thought they’d never see Dom and the rest of the crew back in action, but thankfully, US star Vin Diesel himself confirmed that The Fate of the Furious is fueling up for another go. The actor’s character, Dom, turns to the dark side, funded by new enemy Cipher, played by South African actress Charlize Theron. Can the rest of Dom’s family join together to bring their old leader down? Find out in April.Release Date: 4/14/17Spider-Man: HomecomingSpider Man is heading home to Marvel Studios for the first time. The movie will show us Peter Parker’s high school days, and will continue the threads we saw formed during his initial appearance in Captain America: Civil War. We know that Michael Keaton is playing The Vulture in this story, and that both Happy Hogan and Tony Stark, played by US actors Jon Favreau and Robert Downey Jr., are along for the ride. But it’s Tom Holland’s show as Spider-Man, so let’s see what he has in store.Release Date: 7/7/1721. Which of the following movies can’t you see on May Day?A. Kong: Skull Island.B.

This list should give you some ideas on how to get more from your coke than usual.1. Coca Cola is an excellent rust buster (除锈剂). If you have a bunch of small rusty objects, put them in coke overnight and give them a good scrub in the morning. Coke helps to break down the rust, making cleaning much easier. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.2. Like the previous item, the citric acid (柠檬酸) in coke makes for an excellent window cleaner. This is especially useful for car windows. Pour a can of coke over the window and rub the window, then wipe it off with a wet cloth to remove any sugary matter from the sugar in the drink. As coke is full of sugar, you should clean the sticky matter off the window glasses, or it will be nota cleaner but a dirt.3. For those of you who live in areas where skunk (臭鼬) smells can be an issue from time totime, one can of coke added to water with detergent (清洁剂) really helps to break the smell down. If you have been sprayed, stand in the shower and cover yourself from head to toe with coke —wait for a few minutes, then wash yourself with a shower. Coke is an excellent hair treatment so you get two tips for the price of one with this item!4. Pots can sometimes get black on the bottom. The black is almost impossible to remove; this is caused by over-cooking. To remove the black and renew your pot, pour in a can of coke (or as much as you need to cover the blackened area by an inch) and put it on the stove on a low heat. After an hour or so, wash the pot as normal.24. What does the underlined word ‘‘scrub” in Paragraph 2 probably m ean?A. Start.B. Cleaning.C. Shake.D. Example.25. What is important while using coke to clean car windows?A. Use a dry cloth.B. Rub the window lightly.C. Don’t pour too much coke.D. Clean the sugary matter thoroughly.26. For which purpose does coke have to be mixed with other material?A. To get rid of the black on the pot.B. To break down the rust,C. To remove smells.D. To clean windows.27. What type of writing is this text?A. An advertisement.B. A review.C. A news report.D. A practical guide.CBethany Burke was packing for a family vacation when she glanced in the mirror and froze. She saw a small ugly red bump in the middle of her forehead. “That’s the worst,” she remembers thinking. She had no idea, however, how much worse it would get.Bethany, then a 15-year-old high school student tried to forget about the bump as she boarded a flight from her hometown of Austin, Texas, to Portland, Oregon. But during the flight the bump grew. And grew. And grew.After the plane landed, more bumps appeared, including one close to her eye. Her parents took her to the nearest emergency room. As it turns out, Bethany had been attacked by a superbug (超级病菌).Superbugs were once a problem only in hospitals and nursing homes. In the past decade,though, they have been affecting healthy children and adults as well. In a few hours, they can cause life-threatening infections.“Teens, especially student athletes, can be easily hurt because superbugs stay in warm, damp places where people come into close contact with each other, such as school locker rooms and gyms,” says Dr. Aaron Glatt, an infectious disease specialist. “If you get cut playing sports, and you come into contact with a superbug on a mat, you give it a way to get in,” he explains.As for Bethany, she says the doctor didn’t seem too concerned. “He just handed me this pill, an antibiotic (抗生素),” Bethany says. “He gave us the impression that it was going to clear up very fast.”It didn’t take long for Bethany to realize the antibiotics the doctor had given her weren’t working. One of the bumps grew so large that she could no longer open her eye, and her pain increased. Her parents rushed her to another hospital. The new medicines seemed to start working. Her fever dropped, and the bumps stopped growing.Luckily for Bethany, there were still three powerful antibiotics that together were able to fight off her infection. But what happens when superbugs become resistant even to those drugs? For doctors, that’s the bi ggest worry.28. Bethany discovered a bump on her forehead .A. after the plane for Portland landedB. when she came back from a vacationC. after she boarded a flight from AustinD. when she was preparing for a vacation29. Student athletes are likely to be attacked by superbugs partly because .A. they sweat a lotB. they are often tiredC. they are healthy and strongD. they often wear dirty clothes30. How did Bethany feel after taking the pills given by the doctor in the nearest emergency room?A. Even worse.B. Much belter.C. A little better.D. As terrible as before.31. Doctors are most worried that .A. antibiotics are being overusedB. teens are being attacked by superbugsC. superbugs may become resistant to all drugsD. more people will get infected with superbugsDThere’s an old joke about how you can never buy beer-just rent it. Who would think that the same joke applies to book buying in the digital age? But that’s the case. Many people who w ill be loading their iPads or Amazon Kindles with bestsellers or classics won’t have any idea how limited their rights are as their books, “owners”. Unlike the owners of a physical book, they won’t have the unlimited right to lend an e-book, give it away, or resell it.All these restrictions “raise obvious questions about what ‘ownership’ is,” observes Dan Gillmor, an expert on digital media. “The companies that license stuff digitally have made it clear that you own nothing.” The rules are based on the 1998 Digital Millennium Copyright Act (DMCA), with which Congress hoped to balance the rights of copyright holders and content users. “In the digital environment, that’s always been the trickiest balance to achieve,” Annemarie Bridy, a specialist said.Both camps have important fights to protect. In the digital world, technology allows infinite (无限的) copies to be made. One could give away an e-book and still have it to read. This becomes a great threat to the livelihood of authors, artists, filmmakers and musicians. So some limitation is sensible. That’s usually done through digital rights management, or DRM, which encodes (编码) copy limitations into the digital file. The DMCA protected DRM. The question is whether the balance has given an unfair advantage to the booksellers, at the consumers expense. The answer is yes.For one thing, DRM has put far too much power in the hands of digital booksellers. In 2009, Amazon simply deleted some e-books from buyers, Kindles secretly. An uproar (鼓噪) followed. Amazon then p romised never to steal a book back from a Kindle without the device owner’s permission. But in early 2012, the company shut down the access of Linn Jordet Nygaard, a Norwegian Kindle owner, to her library of 43 e-books. Another uproar followed, and Amazon backed down again, restoring Nygaard’s account.Another problem of e-book DRM is that most e-books are tied to the seller’s reading device. Buy a book from Amazon, and you can read it only on a Kindle or Amazon app. This lock-in gives the booksellers power over not only consumers but publishers.Moreover, nowhere does Amazon, Apple or any other distributor promise to support itsdigital formats forever. There are ways to protect your e-books by changing the format. But is it legal? No one is quite sure.The guiding principle must he that an e-book owner’s rights and responsibilities parallel those of a printed book owner, and the same must apply to authors, publishers and booksellers. Clarify these rules, and the book market will reap the benefit.Leave the rules as vague (模糊的;含糊的) as they are, and the victims will be authors, consumers and publishers.32. The author mentions the old joke to say that .A. book buying is easier in the digital ageB. buyers do not really own their e-booksC. it is a good choice just to borrow e-booksD. e-books are convenient compared with physical ones33. Which of the following is TRUE about the DMCA?A. It turned out to benefit digital booksellers.B. It seems a little unfair to digital booksellers.C. It has become a threat to the livelihood of authors.D. It actually played a trick on copyright holders and content users.34. The underlined part “backed down” in Para. 4 probably means .A. felt guiltyB. gave inC. broke a promiseD. made an apology35. What is the author’s suggestion?A. Booksellers should be punished by law for their marketing strategy.B. Booksellers should make a formal public apology to the victims.C. E-book readers should buy e-books directly from publishers.D. E-books should be treated the same as physical books.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人空白处的最佳选项,选项中有两项多余选项。
