Grammar and vocabularySection ADirections: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word;for the other blanks, use one word that best fits each blank.Pioneers in artificial intelligence win the Nobel Prize in physicsThe 2024 Nobel Prize in physics has been awarded to JohnHopfield and Geoffrey Hinton. They are known for theirfundamental discoveries in machine learning, ___1___paved theway for how artificial intelligence is used today.Machine learning differs from traditional software. The softwarereceives data, which is processed according to a“clear description, and___2___(produce)the results. In machine learning, the computer learns by example, enabling it to tackle problems that are too complicated ___3___(manage)by step-by-step instructions.Hinton and Hopfield___4___(credit)with using tools from physics to advance basic research in the field. In 1982, Hopfield developed a model of neural(神经的)networks, today known as the Hopfield network, to describe how the brain recalls memories when___5___(feed)partial information, similar to the method your brain uses to remember a word on the tip of your tongue.Geoff Hinton and colleagues further developed the Hopfield network. To do that, Hinton used statistical physics, based on an equation invented by the nineteenth century physicist Ludwig Boltzmann, creating a "Boltzmann machine. "It can learn—not from instructions, but from ___ 6___(give)examples. A trained Boltzmann machine can recognize familiar traits(特质)in information it has not previously seen. Imagine meeting a friend's brother or sister, and you can immediately see that they___7___be related. In a similar way, the Boltzmann machine can recognize an entirely new example___8___it belongs to a category found in the training material.Hinton has also urged caution around the technology. Hinton quit his job as a vice president last year at a tech giant. He said he left because he wanted to be able to share his concerns about the risks of artificial intelligence without worrying___9___it would mean for his employer. "One of the ways in which these systems might escape control is by writing their own computer code to modify ___ 10___, ”Hinton said in a 2023interview. "That's something we need to seriously worry about. "Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can be usedA hacker' s lifeHave you ever locked yourself out of your home and had to try to break in?First, you get a sense of___11___in succeeding. But then comes the worrying realization that if you can break into your own place as a(n)___12___, a professional could do so five times faster. So you look at the weak point in your security and fix it. Well, that's more or less how the DefCon hackers conference works.Every year passionate hackers meet at DefCon in Las Vegas to___13___ their knowledge and capabilities. Mention the word 'hacker'and many of us ___14___a seventeen-year-old geek(怪人)sitting in their bedroom, illegally hacking into the US's defence secrets in the Pentagon(五角大楼). Or we just think 'criminals'. But that is actually a misrepresentation of what most hackers do.The activities and experiments that take place at DefCon have an enormous impact on our daily lives. These are people who love the challenge of finding security gaps: computer ___15___ who can't break the habit. They look with great care at all kinds of systems, from the Internet to mobile communications to ___16___ door locks. And then they try to hack them. In doing so, they are doing all of us a great service, because they pass on their findings to the industries that design the systems, which are then able to___17___ the security holes.A typical example of this is when I attended a presentation on electronic door locks. Ironically, one of the most secure locks they demonstrated was a 4, 000-year-old Egyptian lock. But when it came to more modern devices, the presenters revealed ___18___ weaknesses in several brands of electro-mechanical locks. A bio-lock that uses a fingerprint scan for entry was___19___ , easily, by a paper clip. (Unfortunately, although all the manufacturers of the insecure locks were ___20____, not all of them responded. )II. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.When is anger justified?Anger is a complicated emotion. But is it ever morally right to be angry?And if so, when?One of the most foundational understandings of ___21___ comes from the Greek philosopher Aristotle. In his model, there's a sweet spot for our actions and emotional reactions, and it's up to you to develop practical wisdom about when you should feel what and how strongly to feel it.___22___ , let's say you're going to sleep early because you have an important meetingtomorrow and your neighbor just started playing loud music. If you can't sleep, you might ruin your meeting, so feeling angry is definitely ___23___ . But how much anger should you feel?And what actions, if any, should you take?To answer these questions, Aristotle would need to know more details. Have you ___24___ talked to your neighbor about this issue?Is it a reasonable time to be playing music?Is your neighbor trying to___25___ you, or are they just enjoying their evening?Relying on practical wisdom in Aristotle's case-by-case approach makes a lot of sense for handling 26 conflicts. But what about when there's no one to___27___for your anger?Imagine a tornado completely destroys your house while your neighbor's home is___28___. No amount of anger can undo the disaster, and there isn't really a suitable 29for your frustration.Although it's hard for us to control our anger, there might be something we can learn from it. Philosopher PF Strawson's theory suggests that experiencing anger is a natural part of human psychology that helps us communicate blame and hold each other 30, In this model, anger can___be an important part of letting us know when something immoral is happening, so ___31___ it would harm our social lives and moral communities. But finding the right response to those psychological alarm bells can be 32_. For instance, if you were supervising cruel, disrespectful young children, it might be natural to feel anger, but it would be___33___to treat their moral mistakes like those of adults.So when should you ___34___ anger?And can it ever help change things for the better?Let's imagine your community is experiencing serious health issues because a nearby factory is ___35___polluting the water supply. In unjust situations like this, it could be a moral mistake to suppress(压制)your anger, instead of channeling it into positive action.21, A. motion B. passion C. urge D. anger22. A. In conclusion B. However C. What's more D. For example23. A. exceptional B. understandable C. useless D. tragic24. A. remotely B. reluctantly C. previously D. ultimately25.

A. illegally B. remotely C. steadily D. inevitably Section BDirections: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Caroline Robbins knew that the first day of school was very, very important. Why?Because that was the day when you chose where you would sit for the entire year. Caroline realized that in some classes this choice would be made for her. The teacher would place students in alphaberical(按字母顺序的)order, meaning she would have to sit in front of Zach Rodgers yet again. Zach was attracted by Caroline, and would distract her from her work by passing notes and telling jokes to impress her. In general, being a Robbins was pretty good, but having to sit in front of Zach was definitely a drawback.In her other classes, though, Caroline would be sure to choose just the right seat. Caroline liked to think of herself as one of the cool kids, but she also did well in school and liked learning. So, Caroline wanted to sit close to the cool kids, but not too close, or she would be more interested in talking than paying attention. She also knew that it was good to be friends with the smart kids, because they could help Caroline with her schoolwork. However, she didn't want to sit too close to the smart kids. Unfortunately, at Caroline's school, the smart kids and the cool kids were not the same kids.Caroline had all of this in mind as she walked through the school's front door on the first day. She knew where her first class was, but she didn't want to be the first one there. If you were the first one there, you didn't have any control at all!Other people got to choose how close they sat to you, not the other way around. This simply would not do. So, she took her time walking down the hall, taking a minute to talk to her friend Alma, whom she hadn't seen for the entire summer.At last, she walked through the door of her first class, and there it was, the perfect seat!Two seats away from Jasmine, the smartest girl in her entire grade, and just in front of Marc, who was very cool and totally cute.There was a new guy to the left, which could be a risk, but how bad could a new guy be?So Caroline started toward the seat, being careful not to rush, when Marc's best friend Jason sat down in her chair!Sure, there were other seats, but no other perfect ones. Saddened but not discouraged, Caroline sat down in the second-best seat and immediately started planning for lunchtime, when she was determined to get the best seat in the cafeteria.36. As used in paragraph 1, the word“drawback”most nearly means“_____”A. disadvantageB. benefitC. virtueD. withdrawal37. What can be inferred from paragraph 2?A. Caroline was often seen as a cool kid, not a smart kid.B. Caroline wanted to be the only smart kid in her school.C. If Caroline was seen as a smart kid, no one would think she was cool.D. Caroline's school was unusual in that smart kids were also cool.38. According to the passage, Caroline makes sure not to get to class too Early by____.A. taking time to fix her hairB. going to the wrong classC. waiting outside the school gateD. stopping to talk to her friend39. How did Caroline feel about the new guy sitting next to her desired seat?A. She was thrilled to have a new friend to sit next to.B. She was concerned he might be a disturbance.C. She was relieved that he didn't take the perfect seat.D. She was disappointed because he didn't look cool.(B)From the time human beings began to draw them, maps have helped people find their way around their environments. But maps can show us many things, not just which direction to go. They show the path of history, the earth's shape development of mathematics, and the progress of technology.One of the oldest-known land maps is an almost 1, 600-year-old tablet from Southwest Asia. The map shows a circle of land that is divided by a river and surrounded by ocean. Triangles on the map indicate eight different regions. And the map's text describes legendary beasts and heroes that were important to the ancient people of the area. Around AD 150, a Greek scientist drew north-south and east-west lines on a map. This addition applies mathematics to mapping and was an early attempt to show the earth's shape on a flat piece of paper. Maps gradually became much more detailed as new regions were explored and put down on paper. Also, mathematical and astronomical advances helped to perfect the world map to what we know and love today!Now that you know a little about the early history of maps, lets learn some fun facts.East at the TopThese days, most maps feature north at the top. However, during the Middle Ages, most maps had east a the top. This was done to point in the direction of the morning sun.Puzzle MapsWhen printed maps became available to the general population in the eighteenth and nineteenth centuries, not everyone could understand them. In fact, the first jigsaw puzzles(拼图游戏)were designed as practice maps for Eighteenth-century geography classes!Fake PlacesMapmakers need to make sure that their work is not copied by others. To protect their work, many mapmakers add made-up towns or streets to their maps. Only the original mapmaker would know about the fake entry.Modern TechnologyToday, digital maps and GPS technology have revolutionized the way we explore our world. With the touch of a screen, we can see our exact location, plan routes, and even view real-time traffic updates.40. Which of the followingpictures best shows themodern form of the Greek scientist's addition to the map?41. Fake towns or streets were often added to maps_________ .A. so that it would be clear if someone copied the mapB. to make the maps less boring and more accurateC. as a tricky challenge for people to take onD. to help people practice how to read complicated maps42. What is the main purpose of the passage?A. To show the development of mapping technology.B. To explain the importance of maps throughout history.C. To introduce the history of maps and some interesting facts.D. To teach some map-making tricks and techniques.(C)Most taxi drivers need a smartphone to get to their destinations. But sharks, it seems, need nothing more than their own bodies—and Earth's magneric(磁的)field. A new study suggests some sharks can read Earth's field like a map and use it to travel long distances with accuracy.Since the 1970s, researchers have suspected that some fish can detect magnetic fields. But no one had shown that sharks use the fields to find their location or navigate(导航), partly because the animals aren't so easy to work with. It's one thing if you have a small fish, or a baby sea turtle, but when you work with sharks, you have to upscale everything.Bryan Keller, an ecologist at Florida State University, and his colleagues decided to do just that. They lined a bedroom-size cage with wire and placed a small swimming pool in the center of the cage. By running an electrical current through the wiring, they could generate a custom magnetic field in the center of the pool. The team then collected 20 young bonnet head sharks—a species known to migrate hundreds of kilometers—off the Florida coast. They placed the sharks into the pool, one at a time, and let them swim freely under three different magnetic fields, applied in random succession. One field mimicked(模仿)Earth's natural field at the spot where the sharks were collected, while the others mimicked the fields at locations 600 kilometers north and 600 kilometers south of their homes.They used software to track the sharks' responses, observing which direction in the tank they were trying to swim towards. When the young sharks were exposed to the magnetic field of the place they were captured, or "home', they stayed put. But when subjected to the southern magnetic field, the sharks persistently changed their headings to swim north, as if trying to get back home. This suggests that the sharks were using the magnetic field to guide them, similar to how humans use GPS.Surprisingly, the researchers found that the sharks didn't favor any direction when swimming under the northern field. Keller says this might be because they don't go north of their home location since there is only land there, and so they rarely have to find their way back south again. “This could support the theory that their ability to go back home is a learned behavior, "he says. They might not know what to do in the northern field because "they've never been up there. "says Keller.Keller's research adds a significant piece to the still-incomplete puzzle of shark biology. Sharks have been declining at an alarming rate due to mostly overfishing and habitat change. Studying the life cycles and migration patterns of sharks can help us understand what areas to protect when managing marine spaces.43. Why is it difficult for researchers to prove that sharks can read Earth's field?A. Sharks are too hard to follow and observe.B. Sharks are not sensitive to magnetic fields.C. Sharks are difficult to study in a laboratory setting.D. Sharks are on the list of endangered species.44. According to Keller, what might be the reason why sharks don't favor any direction when swimming under the northern magnetic field?A. They don't like the climate in the northB. They've never been to the north of their home before.C. They learned to do so when they were young.D. The northern magnetic field was not strong enough.45. From the passage, we can infer that Keller's research is significant because it_______.A. provides anew method for capturing sharksB. supports the idea that sharks' migration patterns are randomC. adds crucial information to our understanding of shark biologyD. suggests that sharks should be protected from overfishing46. What is the main idea of the passage?A. Sharks use Earth's magnetic field to find their way on seas.B. Researchers discovered a new way to study sharks in labs.C. Shark populations are declining due to habitat change.D. Sharks have a learned behavior of returning to their home.Section CDirections: Read the passage carefully. Fill in each blank with a proper sentence given in the box.The power of placebo(安慰剂)Have you ever taken a pill for a headache and felt instant relief even though there's no way the medicine could have taken effect so quickly?If so, you've personally experienced a medical phenomenon known as the placebo effect. ______47______In the above situation regarding your headache, the active ingredient(成分)couldn't have been responsible for your reduced pain. So why did the symptoms improve?Scientists don't completely understand the mechanisms behind the effect, but they have determined that an individual's conditioning and expectations likely play a major role. With your headache, for example, you expected the painkiller to work because pills have relieved your headaches in the past. ______48_______In fact, the latter means a placebo can still work even when someone knows it's not real medicine!Other factors that can influence how well a treatment works include being told it's effective by a doctor, your doctor's body language or tone of voice, and the knowledge that you're taking action to solve the problem.______49______If you believe a drug will be ineffective at relieving your symptoms, for instance, it is less likely to work. Even worse, if you expect to suffer side effects from your medication, you probably will. This puts doctors in a tricky position—they're required by law to inform patients of risks, yet doing so could negatively affect recovery. The best way to avoid this undesirable effect, according to some experts, is for doctors to phrase dangers in the most encouraging way possible or ask people if they're willing to remain unaware of minor side effects.The power of the placebo effect opens up an exciting opportunity to explore new avenues. Though we may not fully grasp how the placebo effects work, one thing is clear: our minds have an amazing ability to shape not only our thoughts but also our physical health. ______ 50______Ⅲ. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s)of the passage in no more than 60 words. Use your own words as far as possible.51.Why we hate phone callsSuddenly a sound rings out, stopping you in your tracks. Panicking, you search for where it could be coming from. It's your phone, and if you're like a quarter of 18 to 30-year-olds in a recent British study, you probably won't answer it. The same study found that 70%of the people in this age group prefer text messages to phone calls. Why do so many young people hate phonecalls?While previous generations grew up using landlines to talk to their friends smartphone-equipped younger people have grown up used to using text messages for social conversations. There's less pressure with texting. You can read and respond to messages on your own schedule, and you can take time to think about what you want to say rather than being put on the spot during a phone call. Besides, when you can craft a reply free of interruption, you have greater control over your contributions to a conversation. Communication like phone calls can lead people to feel a loss of control and the corresponding anxiety. Many young people report associating phone calls, particularly those without prior warning, with bad news.This means that new social codes are being established. Many people will now text someone to see if they're available to take a phone call. If someone doesn't feel able to sum something up in a few short messages, they might leave a long voice note.But this doesn't mean that anxiety around communication has been stopped. Evidence suggests that texting can also cause anxiety. Many times, texting anxiety comes from frustration, fear, and worry over the reactions of other people. For instance, a short response to your long message might be interpreted as a cold shrug and many people report tensions from being "left on read"—when you know someone has read your message, but they don't, or won't, reply.IV. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.52. 房间里堆满了主人从世界各地收来的古董。

2009学年第一学期徐汇区高三年级语文学科
学习能力诊断卷答案要点及评分参考
一、阅读 80分
(一)16分
1.(1分)说明消费时代产生的作家富豪榜和经典写作时代的主流文学是分野的。

(或答第⑶段最后一句话。


2.(2分)因为两者的写作追求不同,郭敬明们追求畅销的写作契合了消费文学时代的需求,有市场传播价值。

3.(2分)C
4.(2分)①为时而著(富有时代精神);②文采斐然便于传唱;③妇孺易懂。

(答出①给一分,答出②③两点的其中一点给一分)
5.(5分)①将文学推向了人们注目的中心;②给作家们树立了一个市场化写作的标杆;③给文化拓展了更红尘的大众化路径;④给大众文化添了娱乐的佐料;⑤是更多年轻人实现文学梦的催化剂;⑥客观上逼迫上榜作家写出传世作品;⑦一定程度上实现了文学作为文化产品的市场使命。

(答出②③④⑤的给3分,答出①⑥⑦其中两点的给2分)
6.(4分)参考示例:蒲松龄的《聊斋志异》揭露封建统治黑暗,塑造了成名、黄英等个性鲜明的艺术形象,成为我国文学创作的宝贵财富。

可是蒲松龄一生穷困,没有因《聊斋》而富裕,所以说财富不完全等同于作家的写作价值。

(二)21分
7.(3分)“短”实指多伦路只有500米长;“长”指多伦路悠久的历史文化及对所在城市长远的影响。

8.(2分)与当年富丽悠闲的多伦路对比,同时与下文叙写改造后的多伦路作对比铺垫。

9.(4分)留下我童年与少女时代成长的印记;马路菜场的石子路及前后的变化;感受鲁迅及左翼进步人士的青春与激情;充满风情且风格各异的海派建筑;旧书店的怀旧气息以及让“我”心动的书籍。

(答到四点给满分)
10.(5分)E、F(答对一个给3分,对两个给5分)
11.(2分)这三个关联词呈递进层次,突显出“我”对古书由发现到动心到迷恋的由浅而深、由识而知的心理变化过程。

12、(5分)相同:两位作者都表达了怀旧、感伤、留恋之情。

不同:《胡同文化》作者认识到封闭的胡同及胡同文化在社会发展中走向没落是必然的,态度达观而理性,无奈中有怀念,批判中有失落。

本文作者认识到在商品经济大潮中多伦路的改造是必须的,担忧中有认同,失落中更多的是期望。

(相同点2分,《胡同文化》1分,本文2分。


(三)13.6分(每空一分,填写超过6空,按前6空评分)
⑴接天莲叶无穷碧;⑵低绮户;⑶何当共剪西窗烛;⑷无案牍之劳形;
⑸君子生非异也;⑹其实难副;⑺工欲善其事;⑻领异标新二月花。

(四)8分
14.(2分)小令;醉翁(六一居士);
15.(3分) D
16.(3分)一个“疑”字,与上阕的“醉”相呼应,交代了产生“行云却在行舟下”“水中别有天”这种感受的两个因素;一是自己醉了,二是湖水清澈、平静,收到了物我一体的艺术效果。

(五)17分
17.(4分)①定罪,判罪,由…而获罪;②刚、刚刚、正好;③拿起、张开;④数落、责备。

18.(2分)A
19.(2分)A C
20.(3分)①(杨政)敢作敢为爱夸耀自己,但他为人忠实(忠诚)于义气(或情谊)。

(采分点:省略句,矜,笃)
②(3分)(他们)认为是被(盗匪)劫持了,拿着兵器站满两旁,杨政神态像平时那样。

(采分点:省略句或被动句,兵,颜色)
21.(3分)三件事:一是冒险为老师向皇帝乞求宽罪;二是平等与皇亲国戚交谈,不屈从权贵;三是敢于指责权贵傲视英才,即使面对兵器也坦然自若。

【参考译文】
杨政字子行,京兆人。

杨政年轻时爱好学习,跟随代郡(地名)的范升学习《梁丘易》。

他擅长讲说经书。

京师因此流传这样一句话:“说经铿铿杨子行。

”他教授的学生有几百人。

(杨政的老师)范升曾被已休的妻子告发,判罪囚禁在大牢里。

杨政就赤裸着上身,用箭穿透自己的耳朵,然后抱着范升的儿子躲在皇帝经常走的御道旁边,等候着皇帝的车驾。

(皇帝经过时)杨政拿着状子,一边叩头一边大声高喊:“范升一辈子娶了三次妻,只有这一个儿子,他刚三岁,(如果杀了范升)一个孤儿不是很可怜吗!”把侍车驾的武士骑兵们担心(杨政)惊吓了(皇帝)的车马,张开弓箭射击杨政,(杨政)仍不肯离开;武士们用戟叉住他,划伤了(杨政的)胸部,(杨政)仍然不肯后退。

(还)坐在地上哭着为(范升)请求脱罪,打动了皇帝,口下旨意“乞谅杨政的老师。

”皇帝立即颁布诏书放了范升,杨政也因此事而扬名。

杨政好酒,不拘小节,敢作敢为爱夸耀自己,但他为人忠实(忠诚)于义气。

当时,皇帝的女婿梁松、皇后的弟弟阴就都仰慕杨政的名声,来拜见(杨)与他结交。

杨政每每与(他们)在一起恳切地讨论问题,从不屈从(他们的观点)。

(杨政)曾经到杨虚侯马武那去(拜见)他,马武不高兴见杨政,称病不起床。

杨政走进(马武)房间,径直登上(马武的)床推着马武,抓住他的臂膀斥责道:“你深受国恩,位居藩辅,不想着寻求贤能来回报(皇帝)对你的恩宠,却小看天下英才,这不该是你的养身之道。

今天敢动一下,我捅了你!”马武的几个儿子以及
侍从大惊失色,认为是被盗匪劫持,拿着兵器站满两边,杨政神态自若(跟平常一样)。

恰逢阴就赶到,训斥马武,命令他与杨政结为朋友。

杨政刚直不阿,(为人处事)任意性情大都像这样。

到建初年间,做了中郎将。

(六)12分
22.(2分)心为形役(或“田园将芜”);《桃花源记》
23.(2分)诗人托物言志,借松、菊的意象表现了他的清高坚贞,寄寓归隐之志。

24.(3分)上文写了回归田园的欢悦,隐含理想受挫的无奈,“已矣乎”这一感叹句贴切地表现了作者抉择“归去”时内心挣扎后的绝决和释然。

25.(2分)B
26.(3分)归途之乐;(天伦)家园之乐;劳作之乐;(田野)出游之乐。

(答对3点给满分)
