广西2024年高考语文模拟试卷及答案35分)现代文阅读I材料一:虚与实,既是一个哲学宇宙观问题,又是一种艺术实践的尺度。
宋人范晞文在《对床夜语》中说:“不以虚为虚,而以实为虚,化景物为情思,从首至尾,自然如行云流水,此其难也。
”以虚为虚,就会陷入纯粹的虚无主义;以实为实,就会机械僵化,全无生气;唯有化实为虚,才能产生无穷的意味。
虚实相生是中国古代诗歌创作的重要艺术手段,这种“诗笔”移植到唐传奇的写作中,首要的贡献就是创造了众多个性鲜明、栩栩如生的人物形象。
唐传奇在塑造人物时,通常是截取人物的几个重要生活片段,而把另外一些内容、事件省略,留下大量空白,让读者通过想象自己去填充。
化实为虚,由虚入实。
如沈既济《任氏传》描写任氏,仅有“容色姝丽”四字正面叙写任氏之美,并无具体的描摹刻画,但其美貌却如在目前,原因就在于作者全从侧面烘托,从虚处着笔,写郑六一见钟情、不能自己,“见之惊悦,策其驴,忽先之,忽后之,将挑而未敢”。
更为精彩的是,韦崟派遣家僮秘密察看之后两人的一段对话,先问之“容若何”,家僮答之“奇怪也!天下未尝见之矣”。
简单的一问一答,任氏的绝美之姿已经跃然纸上。
接着又不厌其烦地拿出其他佳丽进行对比,特别是吴王之第六女,“秾艳如神仙,中表素推第一”,但即便如此美貌,与任氏比起来,仍“非其伦也”。
所有这些铺叙,没有一处正面描摹,全从虚处落笔,由虚入实,这正是诗歌意象创造中的虚实相生之法。
再比如裴铏的《昆仑奴》,虽然磨勒是小说的主人公,但是读者读完全篇,对其所知仍然甚少,他究竟从哪里来,如何具有这样超常的本领,最后又怎样生活等等,这些问题小说中都没有交代,但人物的形象却因此而具有了巨大的张力,那些空白点召唤着读者的参与,每一个读者都可以用自己的审美经验来填补这些空白,而正是阅读接受过程中审美意象的再生成,赋予了小说更深沉的审美意蕴。
像《柳毅传》《莺莺传》《无双传》《虬髯客传》等作品,在人物形象的塑造上,也都充分运用了虚实相生之法,使人物形象生动饱满,具有强大的艺术感染力。

Write your answers on the answer sheet.Passage 1Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor. The type of home you have is another. Things like insulation present energy costs, and the type of system you buy are added factors.Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that’s all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun.We won’t have to worry about the suns running out of energy for another several billion years or so. Besides as an endless source of energy, the use of the sun has other advantages as well. The sun doesn’t offer as many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With solar energy, we will still need sources of energy, but we won’t need as mu ch. That means we can cut down on our pollution problems.With all these good points, why don’t we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed. Solar energy is now in its infancy. It could soon grow to becomea major part of our nations energy supply.41. Which statement best expresses the main idea?[A] Something about Solar Energy and Pollution.[B] Solar Energy.[C] Energy and Pollution.[D] Energy and Money.42. Solar energy can help us save __________.[A] the earth and natural resources [B] mother nature[C] the sun [D] our precious fuel43. The sun is an endless source of energy, it will not run out of it for __________.[A] several million years [B] several hundred years[C] several billion years [D] several thousand years44. Which of the following statements is correct?[A] Energy from coal would not pollute our living environment.[B] Energy from natural gas would not pollute our living environment.[C] Energy from the sun would not pollute our living environment.[D] Energy from oil would not pollute our living environment.45. Solar energy is now in its infancy, __________.[A] but it will be considered as an important part of our nation’s energy supply[B] yet we will build more power plants[C] and the supply of electricity will be rationed[D] but we don t need practice energy rationing nowPassage 2In this age of Internet chat, videogames and reality television, there is no shortage of mindless activities to keep a child occupied. Yet, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last year.As a writer I know about winning contests, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressure of trying to live up to a reputation created by previous victor ies. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.A revelation (启示) came last week when I asked her, “Don’t you want to win again?”“No,” she replied, “I just want to tell the story of an angel going to first grade.”I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel startin g first grade was quickly “guided” by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her contest into my contest without even realizing it.Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my daughter’s experience.While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough a way to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.46. What do we learn from the first paragraph?[A] A lot of distractions compete for children’s time nowadays.[B] Children do find lots of fun in many mindless activities.[C] Rebecca is much too occupied to enjoy her leisure time.[D] Rebecca draws on a lot of online materials for her writing.47. What did the author say about her own writing experience?[A] She was constantly under pressure of writing more.[B] Most of her stories had been rejected by publishers.[C] She did not quite live up to her reputation as a writer.[D] Her way to success was full of pains and frustrations.48. Why did Rebecca want to enter this year’s writing contest?[A] She had won a prize in the previous contest.[B] She wanted to share her stories with readers.[C] She was sure of winning with her mother’s help.[D] She believed she possessed real talent for writing.49. The author took great pains to refine her daughter’s stories because __________.[A] she wanted to help Rebecca realize her dreams of becoming a writer[B] she was afraid Rebecca’s imagination might run wild while writing[C] she did not want to disappoint Rebecca who needed her help so much[D] she believed she had the knowledge and experience to offer guidance50. What’s the author’s advice for parents?[A] Children should be given every chance to voice their opinions.[B] Parents should keep an eye on the activities their kids engage in.[C] Children should be allowed freedom to grow through experience.[D] A writing career, though attractive, is not for every child to pursue.Passage 3Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.Farmers can also call on the services of their local hunt to control the fox population. Hunting consists of pursuing a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox they kill it or a hunter shoots it.People who take part in hunting think of it as a sport; they wear a special uniform of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.It is estimated that up to 100,000 people watch or take part in fox hunting. But over the last couple of decades the number of people opposed to fox hunting, because they think it is brutal (残酷的), has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of confrontation (冲突) between hunters and hunt saboteurs (阻拦者). Sometimes these incidents lead to violence, but mostly saboteurs interfere with the hunt by misleading riders and disturbing the trail of the fox’s smell, which the dogs follow.Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve of a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.51. Rich people in Britain have been hunting foxes __________.[A] for recreation [B] in the interests of the farmers[C] to limit the fox population [D] to show off their wealth52. What is special about fox hunting in Britain?[A] It involves the use of a deadly poison.[B] It is a costly event which rarely occurs.[C] The hunters have set rules to follow.[D] The hunters have to go through strict training.53. Fox hunting opponents often interfere in the game __________.[A] by resorting to violence [B] by confusing the fox hunters[C] by taking legal action [D] by demonstrating on the scene54. A new law may be passed by the British Parliament to __________.[A] prohibit farmers from hunting foxes[B] forbid hunting foxes with dogs[C] stop hunting wild animals in the countryside[D] prevent large-scale fox hunting55. It can be inferred from the passage that __________.[A] Something about Solar Energy and Pollution.[B] limiting the fox population is unnecessary[C] hunting foxes with dogs is considered cruel and violent[D] fox-hunting often leads to confrontation between the poor and the richIV.

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, used one word that best fits each blank.An implant that can cool nerves to block pain signals has been unveiled by researchers who say the device could offer an alternative to drugssuch as opioids (类鸦片活性肽).The team behind the device say it could bring benefits for management of acute pain such as (21)_______ experienced after amputations (截肢)or nerve grafts."We are optimistic that this represents a very promising starting point for an engineering approach (22)_______ treating pain,” said Prof John Rogers of Northwestern University in the US, a co-author of the research. But he cautioned that it might be some time (23) _______ they were available to patients. "As with any implantable device, the regulatory process can be slow, typically (24) _______ (involve) much more extensive animal model studies over a period of years," he said.Writing in the journal Science, the team report that the device to block pain signals, which (25) _______(test) only on rats so far, involves a pump, external control system and an implant made from a soft, rubbery substance. The latter forms a sealed collection of tiny channels which form a twisting path in the part of the implant that sits around the target nerve like a cuff.When liquid coolant and dry nitrogen flow through the implant, the liquid causes a drop in temperature. An electronic sensor in the device allows the temperature at the nerve (26) _______(keep) constant."All body processes are based on metabolic chemical reactions, motions of ions and flows of fluids--all (27) _______slow down as a result ofcooling,” said Rogers. “ The net effect when cooling is applied to a nerve is in blocking of electrical signals."Among their experiments, the team tracked two rats with an injury, recording over a three- week period the minimum force that (28)_______be applied to the hind paw to cause the animal to retract (缩回)it. This data was then compared against three rats who were similarly injured but also had the implant. The results suggest bouts of cooling of the injured nerve from 37℃ to 10℃led to (29) _______(severe) pain, with a sevenfold increase in the force that could be applied to the paw. The team say the implant’s benefits include (30)_______, in contrast to opioids, it is not addictive. As the implant is made with water-soluble and biocompatible materials, it can break down in the body after use. The implant could be inserted as an extension of the patient’s initial surgery.Section BDirections: Complete the following passage by using the -words in the box. Each word can only be used once.

Fitted with GPS collars and tattooed with identification numbers on their gums, the bears are also among the latest (34) _______of a long-term research study being conducted by Rich Beausoleil and Lindsay Welfelt, both biologists and bear and cougar specialists.The siblings were only two weeks old when a forest worker and his dog (35) _______ disturbed their den in February 2020, scaring away their mother. She never returned.The worker contacted the WDFW, an agency (36) _______with PAWS to rehabilitate sick, injured wild animals before releasing them back into their natural habitats."Their eyes and ears weren't open, and their teeth hadn't evenerupted,Jennifer Convy, PAWS senior director of wildlife, said of the cubs, which each weighed less than 2 pounds when they arrived and were the youngest ever to be raised at the center.Though (37) _______at first, the cubs weren't cuddled. Instead, their caregivers wore bear- scented bear suits during feedings once the cubs' eyes had opened. At PAWS, the staff and volunteers take pains to be (38)_______to all the animals in their care."They don't see us, ever. We don't talk to them. We don't name the animals because we don't want our staff or volunteers to get (39)_______,“ Convy said. After more than a year, the bear siblings were released.The wildlife biologists are studying how the bears raised at PAWS fare after their release, compared to their wild-reared brethren. One cub released in 2017 had her first litter of cubs in January."We've been to her den several times." Beausoleil said. "She (40)_______ and had cubs of her own ... This was kind of a turning point for us."After all, the whole point of PAWS' rehabilitation "is to protect and perpetuate (使持续) the species," he said.III.

A note written in a manuscript in the library (42) _______the account of da Vinci's first biographer, Giorgio Vasari: that the sitter was a merchanfs wife, Lisa Gherardini. The note also helped date the masterpiece to between 1503 and 1506.A(n) (43)_______ mystery-"Where "- is still in dispute. But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had (44) _______the landscape in the background of the painting. Arguments had (45)_______ been made for stretches of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr Cotte maintained that the artist was more plausibly depicting a part of his native Tuscany 一one that keenly interested him at the time. According to this theory, da Vinci represented the area not as it was, but as, in an unrealised scheme, he (46) _______ it to be.Mr Cotte, who was asked by the Louvre (where the "Mona Lisa" hangs) to create a digital image of the painting, is the inventor of themultispectral camera: a device that can detect not only the drawing below the (47) _______of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a pointed rock, that he found a(n) (48) _______sketch showing that da Vinci meant it to represent a castellated tower.The landscape of the "Mona Lisa" also includes a huge overhanging cliff. That is (49)_______ to one that da Vinci included in a sketch of a fortress (堡垒)contested by Pisa and Florence in the war that flared between them in 1503 (around the time he was painting Gherardini). The (50)_______ with the nearby cliff ——and a tower, known as the Caprona tower 一all overlook the river Amo as it snakes from Florence to Pisa. All three also feature in drawings made by da Vinci to illustrate a plan about which, says Mr Cotte, he became “(51) _______”.This involved diverting the Amo to (52) _______Pisa's water supply and give Florence an outlet to the Mediterranean. In the early 1500s, with the two citystates at war, the idea was under active consideration. Mr Cotte argues that a(n) (53) _______ winding through desolate countryside at the right of the "Mona Lisa" is too wide to be a road, as some have speculated, and is(54) _______the driedup bed of the Amo as da Vinci envisaged (设想)it once his plan had been adopted.It never was. But if Mr Cotte's theory is right, it might just explain why Gherardini, a Florentine, exhibits such a contented, if mysterious, (55)_______。
