She did not know if she was going to make it and wanted to give up. She was tired of fighting and struggling. It seemed as one problem was solved a new one arose.Her father, a cook, took her to the kitchen. He filled three pots with water and placed each on a high fire. Soon the pots came to a boil. In one he placed carrots, in the second he placed eggs, and in the last he placed ground coffee beans. He let them sit and boil, without saying a word.The daughter sucked her teeth and impatiently waited, wondering what he was doing. In about twenty minutes he turned off the burners. He fished the carrots out and placed them in a bowl. He pulled the eggs out and placed them in a bowl. Then he ladled the coffee out and placed it in a mug. Turning to her, he asked, “Darling, what do you see?”“Carrots, eggs, and coffee,” she replied.He brought her closer and asked her to feel the carrots. She did and noted that they were soft. He then asked her to take an egg and break it. After pulling off the shell, she observed the hard-boiled egg. Finally, he asked her to sip the coffee. She smiled, as she tasted its rich aroma.“What does it mean, father?” she humbly asked.He explained that each of them had faced the same adversity, boiling water, but each reacted differently. The carrot went in strong, hard, and unrelenting; but after being subjected to the boiling water, it became softened and weak. The egg had been fragile; its thin outer shell had protected its liquid interior; but after sitting through the boiling water, its inside became hardened.The ground coffee beans were unique, however; after they were in the boiling water, they had changed the water.“Which are you?” he asked his daughter.4.Why did the daughter complain to her father?A.Because she found life was extremely cruel to her.B.Because she found that she was at a loss in her life.C.Because she was tired of fighting and struggling with others.D.Because she doubted if she’d make it to addressing the boredom in life.5.What did the father take his daughter to the kitchen for?A.To boil three things for her.B.To explain to her what life is.C.To give her some inspiration.D.To carry out an experiment with her. 6.What can be inferred from the text?A.The father seemed to be in favor of the egg most.B.The carrot was likely to be the daughter’s favourite.C.The three things all stood the test of the boiling water.D.The ground coffee beans chose to affect their surroundings.7.What’s the best title for the text?A.A vivid lesson B.A best choiceC.A tough challenge D.A rough rideWhen driving, Clara-Marina Martinez makes a note of any unusual behaviour she sees on the road. She then feeds these into machine-learning algorithms (算法), a form of AI, which she is helping develop for Porsche Engineering.Those algorithms are intended to produce a system reliable enough for a car to drive itself. Such a fully autonomous car, known in the industry as Level 5, should be able to complete anentire journey without any intervention (介入) from the driver, and deal with all situations on the road. But this is proving hard to achieve, and many attempts to do so are being abandoned. Last year, for instance, Uber sold off its unit developing self-driving cars.Autonomous vehicles are said to be not just convenient but potentially safer. However, just as people take time to learn how to drive safely, so do machines. And machines are not quick learners. The RAND Corporation calculates that to develop a system 20% safer than a human driver, 100self-driving cars would have to operate 24 hours a day, 365 days a year.Carmakers such as Porsche therefore speed up the development process using simulators (模拟器). These teach software about dangers rarely encountered in reality. Dr Martinez and her colleagues employ “game engines” to do this. These are used to create virtual worlds through which the software can drive. Objects in these virtual worlds are assigned their physical characteristics (ie, buildings are hard, people are soft) so that the sensors in vehicles respond in the appropriate way. Once the software has been trained, it is tested in real autonomous vehicles by re-creating those situations on a test track.How quickly all this will translate into reality remains to be seen. Both regulators and customers will need to overcome the doubt that a software driver really can be safer than a human being.From Porsche’s point of view, though, there is another question. Given that much of the reason owning a sports car is for owners to show off their driving skills, just how big a market will there be for a version where software takes those bragging (炫耀的) rights away?8.Why does Clara-Marina Martinez note the unusual behaviour on the road?A.To market Porsche cars.B.To improve an AI technology.C.To learn to be a responsible driver.D.To enjoy riding in a self-driving car.9.The problem with self-driving cars is that .A.they learn as slowly as human beingsB.they operate for a very short period of timeC.they have to be monitored by human driversD.they need a long time to reach a certain safety level10.What does the underlined word “this” in paragraph 4 refer to?A.Employing simulators on a test track.B.Speeding the development of process.C.Figuring out the physical road dangers.D.Separating the real world from the virtual world.11.What worries Porsche according to the last paragraph?A.The reliability of car software.B.The future of the sports car market.C.The driving skills of human beings.D.The quality of self-driving cars in the future.Studies have shown the mere exposure effect, also referred to as the familiarity principle, inspires our decisions. It is a helpful psychological mechanism that helps us sustain our energy and focus our attention on other things. Getting used to new things takes effort and it can be tiring. So unless we have a terrible experience, we are likely to buy from companies we’ve got used to. That is why companies spend so much money on advertising and marketing and why insurance (保险) companies openly charge existing customers more than new ones.It’s not the case that we only desire things we already know. Some studies suggest when invited to share our preferences, we sometimes see less familiar options as more desirable. But when acting on that preference, we fall back to what we know. This might explain why sometimes the things we want and the things we do don’t quite match up. We might even return to companies that treated us poorly in the past or stay in bad relationships.It’s easy to paint the familiarity principle as an enemy or something to battle as if it is something that holds us back from living our dreams. But this attitude might be overwhelming because it tends to encourage us toward big-picture thinking. Where we imagine that change requires a quite dramatic swing that we don’t feel ready for. Some articles suggest the solution to familiarity frustration (沮丧) is complete exposure to novelty. While this can appear effective in the short term, we may only end up replacing one problem with another. It also risks overwhelm and burnout.So what if we can work with the familiarity principle instead? Familiarity is something wecan learn to play with and enjoy. It is a setting for creativity and a pathway to expansion. We can broaden the zone of familiarity bit by bit. If we think of familiarity as something that can expand, we can consider changing the conditions in and around our lives to make more space for our preferences to take root and grow gently. From here, we will start to make decisions, drawing from an ever-deepening pool of valuable options.12.What allows insurance companies to charge old customers more?A.The advertising cost.B.The improved service.C.The familiarity principle.D.The principle of the market.13.We can learn from paragraph 2 that .A.Our preferences affect our decisionsB.Familiarity tends to generate disrespectC.The familiarity principle is a double-edged swordD.There can be a mismatch between desires and actions14.What is the author’s attitude towards the solution in some articles?A.Disapproving.B.Tolerant.C.Objective.D.Reserved. 15.Which of the following is the best title for the text?A.Step Out of Your Familiarity ZoneB.Spare a Thought for Your PreferenceC.Gently Expand Your Familiarity ZoneD.Give Priority to the Mere Exposure EffectEssential CreativityIn a recent survey in America, 62% of people said that creativity was more important to success in the workplace than they had expected it to be when they were in school.16 It is of course possible to scan people’s brains and see which parts are firing when an idea is created, but rather more romantically it can be thought of as something that cannot be identified. Creativity is what comes to you when you least expect it. You cannot demand creativity from your mind, nor can you demand that you are creative in a particular way.One misconception about creativity is that it is reserved for a few special people. This is not true. 17 Another misconception is that creativity is all about the arts but this simply isn’ttrue. 18It is incredibly important that schools do not prevent creativity. 19 Students should be taught to ask questions and investigate when things do not make sense. They need to learn to view mistakes as opportunities for learning rather than something that was unsuccessful. But now it is worrying that many schools are less concerned with nurturing creativity. However, without creativity, we are indistinguishable from the masses. 20 Meanwhile, we can also channel it to face the challenges of the future.A.We can use it to set ourselves apart.B.It’s difficult to define what creativity is.C.Everyone has the capacity to be creative.D.We can employ creativity to deal with the world.E.Rather, they should work to expand, grow, and exercise it.F.It’s hard to work out where exactly creativity comes from.G.Creativity extends to maths and science in just the way it does to music and literature.二、完形填空Atomic (原子的) shapes are so simple that they can’t be broken down any further. Mathematicians are trying to 21 artificial intelligence (AI) to build a “periodic table” (周期表) of these shapes.Tom Coates at Imperial College London and his colleagues are working to classify (分类) atomic shapes 22 as Fano varieties, which are so simple that they can’t be broken down into smaller 23 . Just as chemists arranged elements in the periodic table by their atomic weight and group to 24 new insights, the researchers hope that organizing these atomic shapes by their various 25 will help in understanding them.The team has assigned each atomic shape a sequence of numbers 26 its features such as the number of holes it has or the 27 to which it twists around itself. This acts as a bar code (条形码) to 28 it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an 29 of 98 percent.The team member Alexander Kasprzyk, who works at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to 30 the periodic table, 31 when you read from left to right, or up and down, there seem to be organized patterns in the geometry (几何) of the shapes.The team hopes to 32 the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes, which could 33 benefit further study.Graham Niblo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by the AI and creates proofs of these ideas. “AI has 34 got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new 35 that allows us to explore parts of the mathematical landscape that are out of reach.”21.A.go about B.turn to C.break with D.throw in 22.A.rewarded B.encountered C.entitled D.diverged 23.A.components B.perspectives C.variations D.transformations 24.A.enhance B.estimate C.reveal D.guarantee 25.A.predictions B.properties C.arrangements D.allowances 26.A.trapped in B.compared to C.bent on D.based on 27.A.scale B.extent C.width D.dimension 28.A.identify B.grasp C.imply D.cast 29.A.concept B.impression C.essence D.accuracy 30.A.differ B.follow C.multiple D.claim31.A.as though B.even if C.so that D.now that 32.A.display B.expose C.distinguish D.improve 33.A.in turn B.in contrast C.by turns D.in return 34.A.critically B.definitely C.strikingly D.comprehensively 35.A.setting B.booming C.backing D.calling三、语法填空阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

My first day there was a rush-driving to a new clinic and getting used to the clinicalenvironment.As it was all new to me, I took off my rings: my wedding ring, and one that was a gift from my husband. I put them in tissue (纸巾) and placed them beside my computer.During my lunch break, I noticed the tissue and thought that it did not look very clean and threw it into the rubbish bin. I went about my work and my day went well; I met new patients and felt that I had been doing well at work.Driving home at the end of the day, just moments before I reached my house, I noticed that my rings were missing. I felt heat in my body rise, my face burning red. I felt sick to my stomach.I spent an hour or so making calls, trying to find my rings. The first people I called were my manager and clinical leader and they gave me a few phone numbers for cleaners. I got in touch with a lady who managed the cleaning service for the clinic, and she told me that the bins had already been collected.I knew nothing could be done now. I had lost my rings. But after two hours or so, I received the most amazing phone call. The cleaner had gone through the bins and found my rings! I was so thankful to her who had taken the trouble to go through the bins—which is not a pleasant task—to find my priceless rings.I worked at that clinic the following day, so I bought chocolates to thank this wonderful person.

My class has made collages a couple of times already this year.”“Other than feathers and leaves and scraps, what kinds of objects do you user?” Darryl asked.“You can use just about anything you want. Caps of soda bottles, plastic packaging, old postage stamps, and greeting cards are something I’ve used, and this time, I’m also going to cut words and pictures out of old magazines and newspapers. You can even draw or paint on a collage if you want,” said Kasara.“That sounds like fun. Can I make a collage too?” Darryl asked.“Sure. We can work on it together after we finish our homework tonight,” answered Kasara.During the rest of the walk to school, Darryl looked for objects he could use to create his collage, and he continued to look for more things as he walked home that afternoon.He found a piece of string, some shiny, colourful paper, and even some bark from a tree.Kasara laughed as she watched him. “You’re excited about this project, aren’t you?” she asked.“Yeah! I have lots of ideas about how I want my collage to look,” Darryl said.The children arrived at home and first did their homework. Then they gathered the art supplies they would need to make the collage, including scissors, glue, markers, and a stack of old magazines and newspapers. Both children placed on the table all the objects they had found during their walk, and then Kasara unrolled a large piece of poster board and cut it inhalf; half for herself and half for her brother.“I like to arrange the objects before I glue anything down,” Karasa explained to Darryl. “That way. I can make changes if I want to, but once the object are glued on, the collage is pretty permanent.”The children worked together for the rest of the evening. After a few hours, they had glued everything in place and set the collages aside for the glue to dry thoroughly. The next morning, they each went to check on their completed projects.Darryl looked at his sister and grinned (露齿而笑) “You’re the art instructor (指导) of the family now. What will tomorrow’s art project be?” He asked. She Laughed and ruffled (弄乱) his hair.36.Kasara thought Darryl was excited about making a collage because he ________.A.started looking everywhere for objects for his collageB.started his collage the minute he finished his homeworkC.told Kasara that he had lots of ideas about making a collageD.asked Kasara if he could make a collage when she made hers37.What does the underlined word "permanent" mean in the passage?A.Beautiful.B.Together.C.Able to change.D.Unable tochange.38.What did Kasara and Darryl use to make the collage this time?A.Old magazines and newspapers.B.Feathers, leaves and scraps.C.Caps of soda bottles, plastic packaging.D.Old postage stamps and greeting cards. 39.According to the story.

南京市南京市雨花台中学仿写语言表达专项练习一、初中语文试仿写语言表达1.阅读下面的例句,根据提供的材料,依照例句的形式,写一个观点与材料相统一的长句。
无论是六岁能文的初唐杰出诗人王勃,还是七岁就举办个人演唱会的奥地利神童莫扎特,无论是十七岁就名噪世界足坛的巴西球王贝利,还是十八岁就统率东吴千军万马的帅才周瑜,他们的故事告诉我们:初生牛犊不怕虎,自古英雄出少年。

②李时珍几十年如一日地跋山涉水、遍尝百草,终于写出医学巨著《本草纲目》。
2.本文善于运用对比,使人物形象鲜明,给人强烈的感受。
请你也运用对比手法,写一写自己熟悉的某个人物外貌特征的改变。
【课文片段在线】他身材增加了一倍;先前的紫色的圆脸,已经变作灰黄,而且加上了很深的皱纹;眼睛也像他父亲一样,周围都肿得通红,这我知道,在海边种地的人,终日吹着海风,大抵是这样的。
他头上是一顶破毡帽,身上只一件极薄的棉衣,浑身瑟索着;手里提着一个纸包和一支长烟管,那手也不是我所记得的红活圆实的手,却又粗又笨而且开裂,像是松树皮了。
【写法分析】选文运用对比手法,对中年闰土进行了细致的外貌描写。
他“先前的紫色的圆脸,已经变作灰黄”;他那“红活圆实的手”,已变得“又粗又笨而且开裂,像是松树皮了”。
通过“脸色”和“手”的对比,就把少年闰土的可爱、中年闰土生活的艰辛鲜活地展现出来,让人久久难忘。
采用对比手法描写人物外貌,重在抓住某一点写现在,适时穿插对记忆中印象的描述。
