应试人吴兆辉应试人学号18722389应试人所在院系材料科学与工程学院题一: Write a speech about “pure science or applied science, which direction should the Shanghai University chooses”. Please follow the 7 steps in a speech. The words of the speech are at least 300 words. (50 points)Good morning, ladies and gentlemen, I am Wu Zhaohui, the speaker of this report. I am from the School of Materials Science and Engineering. My theme is pure science or applied science, which direction should the Shanghai University chooses. Of course, I think pure science and applied science are very suitable for the development of Shanghai University, but if you choose one, I More inclined to choose application science, I will tell from the following aspects.1. As far as the current development of China is concerned, there is still a certain gap with the world's first echelon. Therefore, there is inevitably a gap in the field of basic scientific research. For the country's prosperity, the most fundamental thing is that Some people, especially most capable people, should apply their talents to solve the industrial problems of the country. In the "Made in China 2025" issued by the State Council in 2015, and our "two hundred years" plan in the 19th report of 2017, China's development focus is still the industrial modernization and manufacturing of the country for some time. The construction of a strong country. Obviously, the task of supporting this beautiful blueprint will inevitably fall on colleges and universities and corporate units. From an industrial point of view, there is no doubt that our applied science is more convincing.2. Of course, this is not to say that pure science is not important. In 1921, British physicist N. Norman Campbell writes that pure science and applied science are the roots and branches of the tree of empirical knowledge; theory and reality are inseparable entities. If they do not cause great damage to both sides, they cannot It is separate. However, the development of our university cannot be out of touch with the times, nor can it run counter to the development strategy of the country.3. In terms of the development of China and the development strategy, in the context of the need for comprehensive industrialization and the construction of a strong country, the tasks of the university naturally have a primary and secondary distinction, so I think that application science should be chosen.题二: Read the article: Nano-structured metal-containing polymer precursors for high temperature non-oxide ceramics and ceramic fibers—syntheses, pyrolyses and properties, JOURNAL OF THE EUROPEAN CERAMIC SOCIETY卷: 22期: 14-15页: 2577-2585出版年: 2002作者: Tsirlin, AM; Shcherbakova, GI; Florina, EK, et al.Write an abstract of it. (50 points)One of the different directions for further development in the field of polymer-derived ceramics is the application of metal-containing precursors, which include polymers containing nanostructured metals.Nano-structured metal-containing polymer precursors have great potential in polymer-derived ceramics. In this paper the synthesis and characterization of nano-metallopolycarbosilanes (nMPCS) and their transformation into ceramic materials are reported. The formation of metal nano-particles via fast thermolysis of metal- containing compounds in polymer solution or melt previously developed by the authors was applied to preceramic polymers.Tetrabenzyltitanium,tetrabenzylzirconium,bis(cyclopentadienil)dichloride-ti tanium and zirconium as well as tetrachlorides of these metals and tetrakis(diethylamino)zirconium were used for the introduction of metal nano-particles. The products were characterized by thermo-gravimetric analysis (TGA), differential scanning calorimetry (DSC), differential-thermal analysis (DTA), gel-penetration (GP)-chromatography, X-ray diffraction (XRD), scanning electron microscopy (SEM) and other special analyses. The results of this study reveal new data for the nMPC manufacturing process. These nMPC contain nanoparticles or metal clusters of 2-4nm diameter. The detailed study of the thermal decomposition of MCC is very important. Cp2ZrCl2 and Zr [N(C2H5)2]4 for the ceramic matrix of CMC, the most suitable additive in nMPCS. The coreless fibers are obtained from nZrPCS and contain up to 3 mass% metal.And future research directions will concentrate on the optimization of oligocarbosilane as raw material and the development of Polycarbosilane (PCS) - metal containing compounds (MCC) system with low reactivity.。
上海大学沈天飞专业英语上课练习答案
上海大学沈天飞专业英语上课练习答案1 Intelligent flight controllers for helicopter control1)A methodology for design of an intelligent helicopter flight controller is presented in this paper. 2)The methodology combines artificial neural network, genetic algorithms, conventional PID-controllers, and fuzzy logic algorithms in the design procedure.3) In this approach, the design of an intelligent controller is based on experimental data collected from actual helicopter flight and not based on analytical models.4) A neural network is trained to learn the dynamic characteristics of the helicopter. 5)Based on the neural model, the coefficients of a PID-controller used for blade angle control are searched for using genetic algorithms. 6)The main rotor speed controller is designed using fuzzy logic algorithm based on knowledge generated from understanding the aerodynamic theory and analyzing the helicopter experimental flight data. 7)The intelligent helicopter flight controller is formed by combining the blade angle PID-controller and the rotor speed fuzzy controller. 8)Simulation results showed that for desired altitude input H d, the intelligent controller was able to generate proper control signals for both the blade angle control and the rotor speed control. 9)The helicopter model altitude output H t follows the desired altitude input H d. 10)The design procedures, theoretical background, results and conclusions are presented in this paper2. EDFA gain modeling using Pspice and neural networks1)A new methodology in modeling the performance of an Erbium Doped Fiber Amplifier (EDFA) Gain is presented in this dissertation. 2)It is based on the gain characteristics of an EDFA under different input signal power spectra and pump levels. 3)The novelty of this dissertation is based on the training and use of a neural network applied to the performance characteristics of an EDFA.;The modeling is divided in two sections. 4)The first model is an electrical equivalent circuit of an EDFA that can be simulated and analyzed by Pspice, a commercial electrical simulation program from OrCad. 5)The second section is the development and implementation of a Neural Network to model the gain response of the EDFA for a given number of input power spectra.;6)In order to provide data and verify the performance of both models, a simulation program was developed. 7)The simulation program's output performance was verified using an EDFA analysis program called Oasix.;8)The results from both models were accurate with respect to the theoretical and experimental data. 9)The electrical equivalent model's output spectrum was proven to match the output of the simulation program. 10)The neural network was trained successfully to identify the EDFA gain spectra to its correspondent input spectrum and pump power level with an accuracy of 98%.4、Characterization and Modeling of the Power Insulated Gate Bipolar T ransistor.The power Insulated Gate Bipolar Transistor (IGBT) is a new switching device designed to overcome the high on-state loss of the power MOSFET. The IGBT behaves as a bipolar transistor which is supplied base current by a MOSFET. The bipolar transistor of the IGBT has a wide base with the base contact at the collector edge of the base and is operated with its base in high-level injection. Because of this, the traditional bipolar transistor models are not adequate for the IGBT and the new model developed in this dissertation must be used. The new model is developedusing ambipolar transport and does not assume the quasi-static condition for the transient analysis.;The new IGBT model is used to describe measurements for extracting the essential physical device parameters of the model. With these extracted parameters, the new IGBT model consistently describes the measured electrical characteristics of IGBTs with different base lifetimes. The important electrical characteristics of the IGBT are the on-state I-V characteristics, the steady-state saturation current, and the switching transient current and voltage waveforms. The transient waveforms are examined in detail for constant anode voltage switching, clamped inductive load switching, and series resistor, inductor load switching.;The disadvantage of the IGBT is its slow turn-off speed relative to that of the power MOSFET. The two methods which have been proposed to reduce the turn-off time of the IGBT are base lifetime reduction and buffer layer inclusion. Both methods have the disadvantage, though, of also increasing the on-state voltage. The buffer layer is a high-doped portion of the bipolar transistor base at the base-emitter junction. The new IGBT model discussed above is extended to include the buffer layer. Using the extended model, it is shown that the buffer layer IGBT can be made to have a faster switching time for a given on-state voltage than that of the nonbuffer layer (lifetime reduction) IGBT.;In summary, a new model is developed for the IGBT. It is shown that the new model must be used to accurately describe the steady-state and transient characteristics of the IGBT. The model is used to compare the effects of lifetime reduction and buffer layer inclusion. The results of the comparison show that a better on-state voltage, switching speed trade-off is obtained using the buffer layer than is obtained using lifetime reduction.5、Developing modeling and simulation methodology for virtual prototype power supply systemThis dissertation develops a modeling and simulation methodology for design, verification, and testing (DVT) power supply system using a virtual prototype. The virtual prototype is implemented before the hardware prototyping to detect most of the design errors and circuit deficiencies that occur in the later stage of a standard hardware design verification and testing procedure. The design iterations and product cost are reduced significantly by using this approach. ^ The proposed modeling and simulation methodology consists of four major parts: system partitioning, multi-level modeling of device/function block, hierarchical test sequence, and multi-level simulation. By applying the proposed methodology, the designer can use the virtual prototype effectively by keeping a short simulation CPU time as well as catching most of the design problems. ^ The proposed virtual prototype DVT procedure is demonstrated by simulating a 5 V power supply system with a main power supply, a bias power supply, and other protection, monitoring circuitry. The total CPU time is about 8 hours for 780 tests that include the basic function test, steady stage analysis, small-signal stability analysis, large-signal transient analysis, subsystem interaction test, and system interaction test. By comparing the simulation results with the measurements, it shows that the virtual prototype can represent the important behavior of the power supply system accurately. Since the proposed virtual prototype DVT procedure verifies the circuit design with different types of the tests over different line and load conditions, many circuit problems that are not obvious in the original circuit design can be detected by the simulation. ^ The developed virtual prototypeDVT procedure is not only capable of detecting most of the design errors, but also plays an important role in design modifications. This dissertation also demonstrates how to analyze the anomalies of the forward converter with active-clamp reset circuit extensively and facilitate the design and improve the circuitperformances by utilizing the virtual prototype. With the help of the virtual prototype, it is the first time that the designer is able to analyze the dynamic behavior of the active-clamp forward converter during large-signal transient and optimize the design correspondingly.7、Adaptive nonlinear control of spacecraftThe problem of spacecraft attitude control and momentum management is addressed using nonlinear controllers based on feedback linearization. A chief limitation of the feedback linearization technique is that it requires an exact cancellation of nonlinear terms in order to obtain linear input-output behavior. Adaptive nonlinear controllers for linearizable systems are investigated to overcome this restriction and to achieve asymptotic linear behavior.The spacecraft attitude control and momentum mangement model is characterized by having uncertain parameters appearing linearly on both sides of the dynamicl equation. Therefore,two adaptive controf laws are developed forgeneral models in which the parameters appear linearly on both sides of the dynamical equations.The spacecraft attitude control and momentum mangement problem is then addressed with the adaptive nonlineu control laws utilized and uncertainties in the spacecraft principal intertias assumed. The adaptive nonlinear approach is shown to effectively control the Space Station attitude and effector momentum, while providingaccurate estimates of inertias. The combined tracking prediction-error based tracking is shown to have improvement over the performance of the tracking-error based adaptive controller.8、Discrete-Time Control of A Spacecraft with Retargetable Flexible Antennas.This dissertation considers the discrete-time control of a spacecraft consisting of a rigid-platform. with retargetable flexible antennas. The mission consists of independent minimum-time maneuvers of each antenna to coincide with predetermined lines of sight, while the platform. is stabilized in an inertial space and elastic vibration of the antennas is suppressed. The system is governed by a set of linearized, time-varying equations of motion. A discrete-time approach permits consideration of the time-varying nature of the system in designing the control law.;Both global and decentralized controls are proposed for a noise-free system with full-state feedback. Initially, a time-varying linear-quadratic regulator (LQR) is implemented, followed by two types of decentralized controllers. First, a collocated control law is devised in which actuator forces are based on the position and velocity at the actuator locations. Next, a new metho d called Substructure-Decentralized Control is proposed, where each flexible substructure is controlled based on state measurements associated with the substructure modes of the separately modeled appendages.;In both global and decentralized cases, a linear control law is first implemented coupled with an open-loop disturbance-accommodating control based on the known inertial disturbances caused by the maneuver. Elastic motion is next controlled using nonlinear (on-off) antenna controllers for each decentralized case. For Substructure-Decentralized Control, the controls translate intoquantized actual controls. Lastly, nonlinear (on-off) control laws are also used to control the rigid-body motion for each case.;Next, the problem of controlling the time-varying system in the presence of noisy actuators and sensors is examined. It is assumed that only displacements, not velocities, are sensed for both rigid-body and elastic motion, making state reconstruction also necessary. A discrete-time, full-order Kalman filter is constructed for the time-varying system. A pseudo-decentralized control is proposed whereby feedback controls are based on system state estimates. As before, both linear and nonlinear controls are implemented. For each case mentioned, a numerical example is presented involving a spacecraft with a single flexible maneuvering antenna.。

They are being used by people.BHave you ever noticed that some people can eat what they want and stay in shape, while others carefully watch what they eat and still put on weight? How annoying! However, scientists are beginning to believe that some people get the ability to stay thin from their parents.Scientists say that when some people eat, their bodies will naturally store the excess energy from food as fat. These people gain weight if they eat more than they need each day. Meanwhile, other people eat more than they need but their bodies are able to “burn off” the extra food without making fat, so they rarely have weight problems.To show that this is true, scientists have experimented on laboratory mice. They gave the mice a special diet with a lot of fat. Some mice gained weight while the other mice stayed thin, even though both groups of mice ate the same amount of food and got the same amount of exercise. Scientists concluded that weight gain seemed to be influenced by genetic (基因的) factors. They also believe they have now identified the genes that may cause this tendency. These genes, according to the scientists, get passed down the generations. Armed with this knowledge, they believe it may be possible to develop medicines thatcan target the genes and stop people from gaining weight.The study of weight gain is becoming more important as the numbers of people who are overweight continues to grow. In theUnited States, over seventy percent of the population have weight problems. This means they are at risk of illness such as high blood pressure and heart disease.Current medicines for weight control do not work very well because they can have serious side effects, such as heart problems. However, it takes a long time to develop and thoroughly test new drugs. Therefore, despite this breakthrough in the study of weight-loss drugs, scientists and health professionals all agree that currently the best way to control weight gain is to have a healthy, balanced diet and an active lifestyle with daily exercise. This will not only help people avoid becoming overweight, but also help them stay healthy and energetic.4. According to the scientists, some people ________.A. are able to stay thin because of genetic factorsB. can eat what they want and stay healthy foreverC. usually keep doing exercise to lose their weightD. don’t eat anything every day but still put on weight5. Some people don’t need to worry about weight problems because ________.A. they eat many vegetablesB. they eat less than othersC. they don’t store any energy from food as fatD. they can burn off the extra food without making fat6. What can we learn from the passage?A. Fewer people will have weight problems in the future.B. People with weight problems may suffer from heart trouble.C. We now have good medicine for people with weight problems.D. The result of the experiments on mice and humans are different.7. What does the last paragraph imply?A. Current medicine solve weight problems well.B. We should exercise regularly and eat properly.C. Taking exercise every day may cause heart problems.D. Testing new drugs is hard because of the side effects.CHave you ever imagined that your simple T-shirt could cool you down by up to5℃on these hot summer days? Thanks to a recent discovery, the possibility is getting closer. While there are many alternatives that manage to keep the body warm, this amazing invention aims to offer real relief for those who are eager to feel comfortable and fresh in the outdoors on extremely hot days.Its inventors, engineers Ma Yaoguang of Zhejiang University and Tao Guangming of Huazhong University of Science and Technology in China, look a completely innovative approach. They designed a special textile dial can absorb body heat and re-emit its energy into space as mid-infrared radiation (MIR). This textile cools both the objects and their surroundings through a technique that is known as radiative cooling, Science reveals. This means that even when it looks like you are wearing a regular shirt, you are actually wearing a device that works like a mirror.Research conducted at Stanford University in 2017 had already managed to cool the wearer by 3℃, but this previous trial was limited. So researchers still need to test the new approach to determine how effectively the new fabric cools while the wearers are standing or walking, and not directly facing the sky, like in their trials. They also need to examine and measure how well it works when T-shirts are not in close contact with the skin.Inventors Yaoguang and Guangming are now looking out for textile manufacturers and clothing brands that are interested in using their fabric. They estimate that the new material will increase clothing manufacturing costs by just 10 percent. “We can make it with mass production which means everybody can get a T-shirt and the cost is basically the same as theirs,” old Yaoguang said.So if you are an athlete or simply someone that has to deal with the extremely high temperatures, be patient because your days of feeling hot and bothered may be corning to an end!8. What is the purpose of the new invention?A. To warm up people's body.B. To cool people off in hot weather.C. To detect the wearers' temperature.D. To protect clothes from becoming wet.9. How does the special product work?A. By turning sunlight into energy.B. By sending out absorbed heat.C. By keeping heat out completely.D. By using light color1 s to reflect sunlight.10. What is the main idea of paragraph 3?A. The invention needs further testing.B. The previous studies lack evidence.C. The new fabric has a good cooling effect.D. The new fabric applies to various situations.11. The invention of the T-shirt may hean example of ________.A. barking up the wrong treeB. robbing Peter to pay PaulC. killing two birds with one stoneD. pulling the cart before the horseDLast summer, I spent four months working in France, where the company I was working for put me up in a house that didn’t have Wi-Fi. I wasn’t looking forward to it.I soon discovered, however, that living in a house without Wi-Fi was easier than I expected.Contact between my friends and family was significantly reduced to the odd text message here and there. I couldn’t enjoy my usual web browsing on BBC iPlayer, social media sites, keeping up to date with the news, or even wanting to know the opening hours of shops in the new area I was in.I didn’t, however, spend a full four months without connecting to a Wi-Fi network. It was only a five minutewalk to the reception where I could connect for free and spend as much time online as I wanted to at my own leisure. It made me think , though , how unnecessary it can be , how unnecessarily we rely on it—how we perhaps rely on it too much. As a person, I was more sociable. I spent more time with my housemates instead of hiding behind a computer screen. I did other things that I wouldn’t necessarily have done if I could have browsed the web at my leisure. I read more, I cooked meals for my friends, and I even tidied up more often. Dare I say it; I learned how to live without Wi-Fi. Dare I say it; I found it was easier than I had imagined.12. What was the writer’s first feeling when finding her house had no Wi-Fi?A. Unexpected.B. Angry.C. Shocked.D. Depressed.13. How did the writer keep in touch with her friends and family without Wi-Fi?A. By writing regularly.B. By text message.C. By video calls.D. By telegram.14. What was the writer’s life like without Wi-Fi?A. Dull.B. Lonely.C. Active.D. Relaxing.15. What can be a suitable title for the text?A. A life without Wi-FiB. Different views on the InternetC.

While there are emojis of almost every kind imaginable, from dinosaurs to joyful tears and eggplants, there is no emoji for forgiveness. Seeing the need to show understanding, aFinnish group decided it was time for a "forgiveness" emoji.Every year, the Unicode Consortium, which sets the standards, adds new emojis to the emoji keyboard on mobile phones and computers. In 2019, the Forgivemoji campaign was launched. Forgivemoji's site made an open call to the public to give their designs for a new forgiveness emoji, with the goal of presenting the symbol to the Unicode Consortium and getting it accepted by people.Tuomo Pesonen, communications director of the Unicode Consortium, explained why the forgiveness emoji isindispensablein today's world. “In our modern communication culture, emojis are an important way of expressing human feelings beyond words.” The campaign gained popularity, reaching over two million people around the world. They received many designs, including a bandaged heart, two holding hands, and people from different cultures hugging.After hundreds of people offered their ideas for this emoji, the winner was announced in February 2020. Former Finnish president Tarja Halonen was selected to choose the winner as she has been important in building bridges between people. The emoji that will be presented to the Unicode Consortium is an image of two hands giving a thumbs-up symbol in front of a heart. If the Unicode Consortium accepts the design, it will become available to the public in late 2021.The Forgivemoji campaign goes far beyond having a strong influence on social media. The message of showing forgiveness and understanding is helpful for the world at large.4. What's the idea behind the Fogivemoji campaign?A. people develop pleasant habits.B. To get people more friendly to each other.C. To pick a forgiveness emoji for the public to use.D. To make mobile phones and computers more convenient to use.5. What does the underlined word “indispensable” in Paragraph 3 mean?A. Necessary.B. Different.C. Changeable.D. Interesting.6. Why was Tarja Halonen selected to choose the winner for the campaign?A. She launched the campaign herself.B. She designed the most popular emoji.C. She was familiar with the emoji history.D. She played an important role in relating people.7. What can be the best title for the text?A. Forgiveness is important for peopleB. Emoji for forgiveness is on the wayC. Emojis are becoming interestingly popularD. Finnish people explore the stories of emojisCJeff Bezos, Elon Musk and Richard Branson have a combined net worth of 400 billion, roughly the size of the GDP of the entire nation of Ireland. And all three men have decided to put vast sums of their wealth into chasing their space travel dreams, creating a modern space race in which ultra — rich men — rather than countries — shoot for the stars.But why the three billionaires choose the crazy plan? Just for the travel dreams? It’s not that simple.As we all know, the space travel is a mirror of comprehensive national strength, whether it’s the cold war or the present. The first space racespannedmultiple presidents and premiers — Kennedy, Krushchev, Brezhnev, Nixon. It made heroes of astronauts and cosmonauts, and it focused national prides. But obviously, this year’s race between the billionaires features none of that national pride or opposing ideas. It’s tax — averse tycoons (大亨) who want to sell high — priced tickets to rich people interested in experiencing weightlessness. Amazon’s Bezos has said he is funding his portion by selling off large chunks of his Amazon stock (股票) — 1 billion or more a year.What are the odds? If anyone is taking bets on how this will end, and who will have the more profitable space tourism business, consider Amazon’s method of making very little profit in order to eat up competition. So, from this point of view, what’s hiding behind this crazy race is business. As a method of expand influence, it is not a bad idea.Richard Branson has carried out his plan on July 12, and Jeff Bezos announced that he will start his space travel on July 20. Bezos is getting some good press because he’s taking Wally Funk along for the ride. She’s thepilot now in her 80s who was kept out of space in the 1960s because she’s a woman. This may be a bonus for him. As for Musk, he thinks these two above are not real space trips, he wants a larger move.Who will win the race in the end? Let’s wait and see.8. Which of the following people might be the potential client of the space travel?A. Daisy aged 45 with a heavy debt.B. Clarkson who doesn’t enjoy taking risks.C. Billy aged 60 with an ample retirement pension.D. Alexander who knows nothing about space travel.9. What stopped Wally Funk flying to space in the 1960s?A. Age.B. Gender.C. Height.D. Disposition.10. What does the author think of the billionaires race?A. Profit — driven.B. Meaningless.C. Foolish.D. Generous.11. What does the underlined word “spanned” in paragraph 3 probably mean?A. Revolved.B. Turned down.C. Entered.D. Leapt through.DDid you know people who live in different parts ofChinahave different habits and preferences? For example, people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical features.A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.The study also found differences in the immune systems of both groups. Most people in southernChinacarry the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.12. What did the new study focus on?A. Regions.B. Eating habits.C. Gene variations.D. Ethnic minority groups.13. What is the main function of the gene FADS2?A. It helps store fat.B. It helps digest meat.C. It helps gain weight.D. It helps treat an illness.14. According to the study, most northerners ________.A. sweat less frequentlyB. are immune to malariaC. prefer vegetables to meatD. are more sensitive to climates15. How many differences did the study find related to genes?A. Two.B. Three.C. Four.D. Five.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

However, we don’t often think of martial arts as possible activities; instead, we rule it out because we think it’s dangerous, uncommon, and even, impossible. Martial arts aren’t considered a sport, right?Well, here’s some good news: you’re wrong! Martial arts aren’t much more common than people think, and you can start learning at any age. Practicing martial arts is a great way to keep in shape, both physically and mentally. They’re much less boring and much lessarduoussport than they’re usually described as in movies, so do not worry that they need a lot of effort.Martial arts generally require you to focus on the position and movement of every one of your legs and arms, sometimes even your breathing too. Think about it: when you leave the gym, your mental state has improved and you are much calmer. This is because you’ve only paid attention to one activity. It is a great way to clear your head. Andpracticing it can help you learn to stay more focused, which is the greatest advantage of martial arts training.Martial arts also improve your coordination (协调性), and greatly improve your posture (姿势). I have personally seen students go from slouching (没精打采) to walking tall with their shoulders back in just a couple of months.There are many styles and countless kinds of martial arts. Whichever one you like better, know that all of them are good choices.4. What can we know about martial arts from the first two paragraphs?A. They often have people hurt.B. They are difficult to practice.C. People have a wrong view on it.D. People practice them more often.5. What does the underlined word “arduous” in paragraph 2 mean?A. Interesting.B. Difficult.C. Friendly.D. Exciting.6. What is the biggest benefit of practicing martial arts?A. Adjusting the breath.B. Enjoying one’s free time.C. Correcting the movement.D. Keeping one’s attention.7. What does the writer think of martial arts?A. They are notsports.B. They attracted many teenagers.C. They are beneficial and helpful.D. They were invented to protect others.CSomeday soon an emoji (表情符号)might really save lives.Hiroyuki Komatsu is a Google engineer who suggested adding a series of new emojis to the standard emoji library. It could help those with food allergies (过敏)understand what they are eating anywhere inthe world. Emojis should cover characters representing major food causing allergies. They make people understand what are used in foods even in foreign countries and safely select meals.Emojis are universal because they are chosen and developed by the Unicode Consortium, a non-profit company that oversees, develops and maintains how text is represented. This is in regards to all software products and standards. It's thanks to the Unicode Standard that when you text a friend six pizza emojis, they’ll see those six pizza pieces on their phone. This is true regardless of whether they use an iPhone or an Android.Because emojis are everywhere and visual(视觉的),they could be helpful for restaurants and food packaging designers. They can communicate whether a product is made with common causing-allergy food. But as Komatsu’s advice argues, many of the most common causing-allergy foods are missing or poorly represented by the present emoji library. For example, there is an emoji for octopus, but nothing for squid. There is a loaf of bread that could symbolize grain, but a picture of wheat could be clearer. The emojis can be more direct when symbolizing foods.It’s not uncommon for the Unicode Consortium to add new emojis to the library: several food-related emojis were put into use last June, including some long-waited food emojis. Apple included support for multiracial emojisin a recent iOS update. An artist even recreated Moby-Dick in emoji characters. Some might be sorry for the continuing death of the written word if Komatsu’s suggestion is accepted, but look on the bright side: if you ever see that happy poop on a box, you’ll know to stay away.8. How will emojis save lives according to the text?A. By showing what the food contains visually.B. By telling the safest places in the world.C. By teaching people how to treat allergies.D. By adding standard emojis about safety.9. What does paragraph 3 mainly tell us?A. Emojis have the same meanings around the world.B. The Unicode Consortium is a non-profit company.C. What emojis represent is different in different places.D. Different mobile operating systems have different emojis.10. What can be the reason for Komatsu’s advice?A. Emojis are easy to mix up.B. Present emojis are not enough.C. Emojis can't interest most users.D. Emojis can't represent foods directly.11. What is the author’s attitude to Komatsu's suggestion?A. Doubtful.B. Worried.C. Supportive.D. Uninterested.DWe use what is known as inner speech, where we talk to ourselves, to evaluate situations and make decisions. Now, a robot has been trained to speak aloud its inner decision-making process, giving us a view of how it responds to contradictory demands.Arianna Pipitone and Antonio Chella at the University of Palermo, Italy, programmed a humanoid robot named Pepper, with software that models human cognitive(认知的)processes, which allowed Pepper to retrieve (检索)relevant information from its memory and find the correct way to act based on human commands, as well as a text — to — speech processor. It allowed Pepper to voice its decision-making process while completing a task, "With inner speech, we can better understand what the robot wants to do and what its plan is," says Chella.The researchers asked Pepper to set a dinner table according to etiquette (礼仪)rules they had programmed into the robot. Inner speech was either enabled or disabled to see how it affected Pepper's ability to do what wasinstructed.When instructed to place a napkin on a fork with its inner speech enabled, Pepper asked itself what the etiquette required and concluded that this request went against the rules it had been given. It then asked the researchers if putting the napkin on the fork was the correct action. When told it was, Pepper said, "OK, I prefer to follow your desire," and explained how it was going to place the napkin on the fork.When asked to do the same task with inner speech disabled, Pepper knew this contradicted etiquette rules, so it didn't perform the task or explain why.With the potential for robots to become more common in the future, this type of programming could help the public understand their abilities and limitations, says Sarah Sebo at theUniversityofChicago. "It maintains people's trust and enables cooperation and interactions between humans and robots," she says. However, this experiment only used a single human participant, says Sebo. "It's unclear how their approach would compare across a wide range of human participants," she says.12. Why does the author mention how people make decisions in the first paragraph?A. To introduce the topic.B. To make comparisons.C. To provide an example.D. To support his argument.13. How did Pepper react to the contradictory instruction with its inner speech enabled?A. It failed to complete the task.B. It followed the etiquette rules.C. It made a random decision.D. It communicated with the researchers.14. What did Sarah Sebo think of the research?A. It was creative but worthless.B. It was a good try but the result was a failure.C. It was inspiring but needed further evidence.D. It was carefully designed but poorly performed.15. Which of the following is the best title for the text?A. Robot Taught To Be PoliteB. Robot Can Explain Its DecisionC. Robot Making Decisions: No Longer A DreamD. Robot-Human Communication: No Longer A Problem第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年上海飞翔日本人补习中心高三英语第一次联考试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BDad’s comb was jade green. I heard he bought it when he married Mum, which made the comb two years older than I was. Every night, he wouldsmile, hand me the comb and say, “Be a good girl and help Daddy clean it, OK?”I was more than happy to do it. At age five this mundane task brought me such joy. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me and place the comb on top of his wallet.About two years later, Dad left his sales job and started his own wholesale business. I started primary school. That was when things started to change. He didn’t come home as much as he used to – just a couple of times a week. And when he did come home, it was always late and I’d already be in bed. I started to get mad. I stopped waiting for him to come home, and stopped going downstairs to check on him.Today, I’m no longer a kid. I’ve graduated from college and got a job. Dad’s business has got back on track. Things are better now. Yet the uncomfortable silence between Dad and me persisted.Two days before my birthday last year, Dad came home early. As usual, I helped him carry his bags into his study. When I turned to leave, he said, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink.I passed the clean comb back to Dad. He looked at it and smiled. But this time, I noticed something different. My dad has aged. He has wrinkles next to his eyes when he smiles, yet his smile is still as heartwarming as before.

Known for fireballs, the Perseids typically light up skies on warm summer nights, leaving “long wake(尾迹)of light and color1 behind them.”Under ideal conditions, sky watchers may see approximately 50-100 meteors per hour with each meteor traveling at 37 miles per second. .Because the meteors appear in all parts of the sky, it will be pretty easy to witness the celestial(天上的)event from anywhere in the world. To get the best show, it is advised to view the Perseids from the Northern Hemisphere(半球)during the pre- dawn hours, ideally between 2 a.m. and dawn. In some cases, sky gazers may be able to seemeteors during this shower as early as 9 or 10 p. m.“If it's not cloudy, pick an observing spot away from bright lights, lie on your back, and look up! You don't need any special equipment to view the Perseids—just your eyes,” NASA wrote on their site, adding that telescopes or binoculars are not recommended due to their small fields of view.Remember to let your eyes become adjusted to the dark. Try to stay off of your phone too, as looking at devices with bright screens will negatively affect your night vision and thus reduce the number of meteors you see!For those who may be unable to view the Perseids in person, a live broadcast will be streaming from NASA's Marshall Space Flight Center, starting around 8 p. m. on Aug. 11 and continuing through sunrise on Aug. 12.8. What can we learn about the Perseids Meteor Shower?A. It will be the best meteor shower in history.B. The ultimate shower only happens on this Wednesday.C. We can observe 50- 100 meteors per hour in any place.D. The Meteors usually have long and bright trails behind them.9. Which of the following may be the best time to view the shower?A. At 4 a. m. on the Northern Hemisphere.B. At 2 p. m. on the Northern Hemisphere.C. At sunrise on the Southern Hemisphere.D. At dawn on the Southern Hemisphere.10. What can be inferred about the observation of Meteors?A. If you use a telescope, you will see more meteors.B. You can use smartphones to record the grand scene.C. The brighter the moon is, the more meteors you can see. .D. Bright lights will reduce the visibility of meteors.11. If you are not available to watch the Perseids personally, you can ________.A. browse the unofficial website of NASAB. watch a video recorded by a flight centerC. stream a live show on Aug. 11 nightD. use special devices to connect with the showerDSalad plants have already been grown in old sheltersand tunnels. Urban farming is a regular topic of interest at places like the World Economic Forum (WEF) in Davos, where leaders consider whether the world's food system, blamed for causing both obesity and malnutrition, can be fixed. There are already plenty of urban farming projects around the world, particularly in the US, Japan and the Netherlands, from urban fish and plant farms to vertical farming.“It's becoming an expanding industry,” said Richard Ballard, one of the founders of the farm Growing Underground. “There're several other businesses starting up in London in containers, and there are other vertical farms around the country now.”Growing Underground is not a standard farm. The rows of crops could be in almost any tunnel, but theseplants are 100 feet below Clapham High Street and show that urban agriculture is, in some cases at least, nota fad. The underground farm has occupied a part of the Second World War air-raid shelters for nearly five years, and Ballard is planning to expand into the rest of the space later this year.Growing Underground supplies herb and salad mixes to grocery shops, supermarkets and restaurants. Being in London creates an advantage, Ballard says, as they can harvest and deliver in an hour.He adds other advantages. Being underground means temperatures never go below 15℃surface greenhouses need to be heated. They can do more harvests: 60 crops a year, compared with about seven in a traditional farm. Electricity to power the lights is a major cost, but the company believes renewable energy will become cheaper.Similar British companies include the Jones Food Company in Lincolnshire, while in the US AeroFarms has several projects in New Jersey, and Edenworks in Brooklyn.12. What do we know about urban farming?A. It leads to a healthier lifestyle.B. It is rarely discussed at the WEF.C. Different farming methods are used.D. Local governments pay efforts to develop it.13.

2019-2020学年上海飞翔日本人补习中心高三英语模拟试卷及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AEver wonder why there are so many people polluting the earth? Ever say to yourself:Hey, I wish that I could do more to help the environment? Have you ever thought about trying to help the earth but never really did it? Well, here are some pretty easyand skillful ideas for that green - earth desire inside you.●Turn off your computer. By leaving it on all day you are creating more CO2than a regular passenger would, driving to and from work in one day.● Ride your bike or carpool (合用汽车).Obviously, youare creating less CO2which will help the ozone(臭氧).● Make a garden. Even simply grow some plants in your kitchen, which will help produce more oxygen while eating up some of that evil CO2.● Buy local groceries. It creates less impact on the environment. Besides, you're supporting your local farmers.● Recycle. You had to see this coming. But you have no idea how much you are helping the environment by simply reusing a water bottle instead of buying a huge pack at the store.● Don't run the water while brushing. It saves you money and helps the water resources.● Open the curtains. Natural light is much prettier and it will keep the energy usage down.● Rechargeable batteries. You have no idea how much it takes to get rid of batteries. Do yourself a favor. Save some money and some energy.1. If you don't want to create more CO2, you may_______.A. turn off your computer or open the curtainsB. turn off your computer or ride your bike or carpoolC. make a garden or open the curtainsD. use rechargeable batteries or make a garden2. Which of the following can best describe the function of the first paragraph?A. Main body.B. Argument.C. Lead - in.D. Conclusion.3. The main idea of the passage is about________.A. the importance of environmental protectionB. some ways about how to prevent pollutionC. some suggestions about how to save energyD. some suggestions about environmental protectionBA world in which extinct creatures could be brought back to life came a step closer yesterday. Australian scientists have managed to extract a gene from a preserved sample of a Tasmanian tiger and make it active. Thebreakthroughhas left them dreaming that one day they will be able to recreate the animal, which died out more than 70 years ago. And if it can be done with the Tasmanian tiger, it may also be possible to resurrect (复活) creatures that have been extinct for far longer.“There used to be a time when extinction meant forever, but no more, ” said Professor Mike Archer. “We are now able to seriously challenge whether those animals that have gone for ever. What has been achieved is a very important step in bringing back those animals that are extinct. And while I think that technically it is still pretty difficult at the moment, we can now see the possibilities. I’m personally convinced that the Tasmanian tiger will be brought back to life in my lifetime.”The breakthrough came after nine years of experiments by scientists at the University of Melbourne, who extracted a gene from one of several tigers preserved in alcohol in a Melbourne museum. They removed the equivalent gene from a mouse embryo implanted the tiger gene and then watched as the mouse continued to grow normally, suggesting the tiger gene had been activated.Team leader Dr. Andrew Pask said it was the first time DNA from an extinct species had been used to “induce (引起) a functional response in another living organism”.However, the animal’s entire gene structure would have to be revived in the same way to even begin the possibility of bringing the Tasmanian tiger back from the dead.Mick Mooney, a wildlife officer ofthe Tasmanian Government, was worried that such developments could encourage people’s indifference to the protection of endangered species.“If people think that we can bring animals back to life after they’ve gone, they will start saying that there is nothing to worry about because we can fix it up later.”4. What does the underlined word “breakthrough” in the l paragraph refer to?A. Scientists have recreated new animals.B. Scientists have resurrected endangered animal.C. It has turned out that some creatures would not go extinct.D. A tiger gene has been extracted successfully and activated.5. Scientists are carrying out the experiments in order to ________.A. bring extinct animals back to lifeB. transplant the genes of tigers into other animalsC. find out what factors lead to the animals’ extinctionD. find a new way to extract animals’ DNA6. Mike Archer thinks that ________.A. scientists now have no technological difficulty reconnecting extinct animalsB. it’ll be a century or so before a Tasmanian tiger walks on the earth againC. humans have come closer in reconnecting extinct animalsD. reconnecting extinct animals is impossible7. We can learn from Mick Mooncy’s words that_________.A. he thought it unnecessary to worry about endangered animalsB. his opinion is in contrast with that of the Tasmanian GovernmentC. he thought people should be encouraged to protect endangered animalsD. he is concerned that bringing extinct animals back to life may have a negative effectCDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually upliftingand danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.8. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.9. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.10. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music11. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by MusicDIn order to help discover spoilage and reduce food waste for supermarkets and consumers, researchers have developed new low-cost, smart phone-linked, eco-friendly spoilage sensors for meat and fish packaging.One in threeUKconsumers throw away food just because it reaches the use-by date, but 60% of the £12.5 billion-worth of food we throw away each year is safe to eat.The researchers, whose findings were published in ACS Sensors, say the sensors could also eventually replace the use-by date—a widely used indicator of being fresh and eatable.The sensors cost two US cents each to make. Known as “paper-based electrical gas sensors (PEGS)”, they detect spoilage gases like ammonia (a poisonous gas with a strong unpleasant smell) in meat and fish products.The information provided by the electronic nose is received by a smart phone, and then you can know whether the food is fresh and safe to eat.The Imperial College London researchers who developed PEGS made the sensors by printing carbon electrodes onto a special type of paper. The materials are eco-friendly and harmless, so they don’t damage the environment and are safe to use in food packaging. The sensors, combined with a tiny electronic system, then inform nearby mobile devices, which identify and understand the data about spoilage gases.Lead author Dr Firat Guder of Imperial’s Department of Bioengineering, said, “Although they’re designed to keep us safe, use-by dates can lead to eatable food being thrown away. They don’t always reflect its actual freshness. In fact, people often get sick from food-borne diseases due to poor storage, even when an item is within its use-by date.”“These sensors are cheap enough so we hope to see supermarkets using them within three years. Our goal is to use PEGS in food packaging to reduce unnecessary food waste.”The authors hope that PEGS could have applications beyond food processing, like sensing chemicals in agriculture, air quality, and detecting disease markers in breath like those involved in kidney disease.12. What is the function of PEGS according to the text?A. To improve the taste of foods.B. To improve the service of stores.C. To help supermarkets store foods.D. To help people test food freshness.13. What role does the smartphone play while PEGS are functioning?A. It acts as an electronic nose.B. It reads the data collected by PEGS.C. It helps print the gas sensors onto paper.D. It discovers the spoilage gases from foods.14. What does Dr. Firat Guder say about use-by dates?A. They are not completely reliable.B. They can help reduce food waste.C. They are based on scientific research.D. They are not accepted by the consumers.15. What does the author mainly talk about in the text?A. The process of researching spoilage sensors.B. A new technology in packaging to reduce food waste.C. The application of spoilage sensors beyond food processing.D. The influence of use-by dates on supermarkets and consumers.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2020届上海飞翔日本人补习中心高三英语第四次联考试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AThe Origins of Famous BrandsOur lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders names, some of the companies we trust every day actually have fascinating and surprising back stories.StarbucksIt seems fitting that the most famous coffee brand in the world would take its name from one of the world’s greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville’sMoby Dick. The founders’ original idea was to name the company after the Captain Ahab’s ship, but they eventually decided that Pequot wasn’t a great name for coffee, so they chose Ahab’s first mate, Starbucks, as the name instead.GoogleGoogle was originally called Backrub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain (域) name, he misspelled “googol” as “google”.NikeOriginally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is alsothe name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.The right name is essential to a company’s success, and a great origin story is just as important as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.1. What is the name of the Captain Ahab’s ship?A. Moby Dick.B. Starbucks.C. Pequot.D. Herman Melville.2. Why did the founders of the Google want to change its name?A. They mistook their name.B. They wanted new customers.C. The company’s original name was too long.D. The company’s search technology was improving rapidly.3. Where does the importance of the origin story of one company lie in?A. It can change the company’s image.B. It can add myth to the company.C. It explains the development of the company to customers.D. It makes customers imagine and purchase its goods.BIf you’ve ever had a dog, you know just how deep a connection you can develop with “man’s best friend”. But a dog has a much shorter life span — about 12 to 15 years long — than humans, which means every dog owner has to go through the heartbreaking moment when their loving pet passes away.Why not make a clone of that dog then? This is the solution offered by a South Korean company, Sooam Biotech Research Foundation. The company has successfully cloned at least 400 dogs, mostly for US customers, ever since it pioneered the technique in 2005. Now, Sooam Biotech is planning to introduce their business toUKdog owners, offering them dogs that look just like their lost ones.Meanwhile, another dog is selected to supply an egg.Researchers then replace the DNA in the egg with that from the skin cell and implant the egg into the womb (子宫) of a female dog. The egg grows into a puppy over the following two months. To clone a dog, researchers first need to take a skin cell from a living dog or one that has just died.The whole process takes less than a day, but it comes at a shockingly high price — around £63,000 (614,000 yuan). But if you can’t afford it now, you can also save the cells in a laboratory and access them at a later date. Just like identical twins of humans, they share the exact same DNA but there will still be small differences between them. “The spots on a Dalmatian clone will be different, for example,” Insung Hwang, head of Sooam Biotech, toldThe Guardian. However, as magical as cloning might sound, there is no guarantee that the cloned dog will be a perfect replica of the original one.Dog owners will also have to accept the fact that personality is not “clone-able”. Apart from genes, personality is also determined by upbringing and environment, which are both “random elements [that] cloning technologies simply cannot overcome”, Professor Tom Kirkwood atNewcastle University,UK, toldThe Telegraph.Perhaps bringing our dogs back with cloning is not the best way to remember them after all.Kirkwood, a dog owner himself, pointed out: “An important aspect of our relationship with them is coming to terms with the pain of letting go.”4. According to the article, Sooam Biotech Research Foundation is ______.A. working on plans to help dog owners enjoy their pets longerB. offering a way to help dogs give birth to more puppiesC. providing a service that will make copies of pet dogsD. introducing a completely new technique to clone dogs5.

Urban farming isstill thought costly and time-consumingDHave you ever done something for someone else—knowing that your actions would solely benefit THEM and not YOU? Maybe you opened a door or donated blood or volunteered in a hospital’s ER during the pandemic. This is called a prosocial behavior. Humans engage in these types of behaviors all the time.But a question remains in science: Are we the only species who do this? As one of out closest s, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.Compared to previous controlled lab-based experiments, the setup for DeTroy’s research was very naturalistic. “We installed a button and a fountain into the chimpanzees’ outer enclosures. When an individual pushes the button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at the fountain when the button is pushed, they, and not the pusher, will be able to drink the juice.In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.“It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn’t benefit themselves from their behavior.” said DeTroy.Further research may reveal what lies behind their prosocial motivation. But for now, it’s safe to assume that chimpanzees are not simply aping human behavior.12. Which of the following belongs to prosocial behaviors?A. Jack participated in voluntary work in the library just to earn credits.B. Mark turned to his classmate for help when feeling stressful in study.C. Tim guided a lost child back home on his way to an important job interview.D. Rose often interrupted the teacher to ask questions actively in the math’s class.13. What is the task of the chimpanzees in the lab-based study?A. Sharing food.B. Making a choice.C. Comforting others.D. Showing sympathy.14. How is DeTroy’s study different from the previous ones?A. It was based on controlled lab experiment.B. It gave juice to the chimpanzees as a reward.C. It offered the tested chimpanzees a natural surrounding.D. It provided a chance for chimpanzees to help their partners.15. What can we learn from DeTroy’s quotes?A. Chimpanzees can develop abilities to help others.B. Chimpanzees have acquired many human behaviors.C. Chimpanzees in the wild is cleverer than those in the lab.D. Chimpanzees displayed prosocial behaviors for certain rewards.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
2019-2020学年上海飞翔日本人补习中心高三英语下学期期末试题及答案解析
2019-2020学年上海飞翔日本人补习中心高三英语下学期期末试题及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AThe “laugh out loud” face is officially the world’s most popular emoji, according to researchers from Adobe (ADBE) who surveyed 7,000 users across the United States, the United Kingdom, Germany, France, Japan, Australia, and South Korea.The “thumbs up” emoji came in second, followed by the “red heart” emoji. The flirtatious “wink and kiss” and “sad face with a tear” emojis respectively rounded out the top five.The software maker on Thursday released the findings from its 2021 Global Emoji Trend Report ahead of World Emoji Day on Saturday.Adobe’s latest Emoji Trend report also examined the three most misunderstood emojis in the world. The “eggplant” symbol edged out the “peach” and the “clown” emojis respectively as the most confusing for users.The vast majority of emoji users (90%) believe the modern —day hieroglyphs make it easier for them to express themselves. Eighty — nine percent of respondents said emojis simplify communicating across language barriers. And 67% said they think people who use emojis are friendlier, funnier and cooler than those who don’t. A slight majority of respondents said they are more comfortable expressing emotions through emojis than talking on the phone or in —person. More than half of global emoji users (55%) said using emojis in communications has positively impacted their mental health. Seventy — six percent of those surveyed said emojis are an important communication tool for creating unity, respect and understanding. And 88% said they feel more empathetic toward people who use emojis.1.What are the three most popular emojis according to the passage?A.clown thumbs up laugh out loudugh out loud thumbs up wink and kissugh out loud thumbs up red heartD.thumbs up red heart sad face with a tear2.Which emoji is the most confusing one for users?A.Peach.B.Eggplant.C.Clown.D.Wink and kiss.3.Which of the following best describes the attitude of most people surveyed to emojis?A.Favorable.B.Passive.C.Indifferent.D.Doubtful.BIt might have been Jimmy Kimmel, or any other sharp-tongued talk show hosts of late-night TV. In this instance, it was Samantha Bee, stating her opposition to childhood vaccinations humorously. “Who are you going to believe?” she asked. “Leading authorities on medical science, or 800 comments on your cousin’s Facebook page?”Joking about science can have serious effects, according to studies by communication scholars. Accordingly, since 2013, Paul, a psychological professor, has conducted studies of how satire (讥讽) can influence people’s beliefs about science, which have shown that if you want to interest people in science and shape their views on hot-button science issues, satirical humor can work better.Many Americans pay little attention to science. Even people who regularly watch TV news receive only scraps of science information in their media diet, because mainstream media outlets devote so little airtime to the subject. On top of that, some Americans may regard science as inaccessible.Yet satirical humor can reach viewers who would never watch NOVA or read — well, National Geographic. Millions of people watch late-night television programs live, and videos of these shows get millions of views on streaming services. In 2016, a vote conducted by the University of Delaware Center indicated that nearly one in 10 said they learned about science from late-night television shows.Late-night hosts may occasionally poke fun at scientists. More often, however, the hosts promote a positive image of science. By making science entertaining to audience with little knowledge of the topic, late-night television could spark science engagement. Furthermore, the researchers concluded that satirical shows had the biggest impact among the least educated viewers, thus helping to narrow a gap in attention to science. Though late-night satirical humor can boost science interest and awareness, it has its limits. Science is complex, and conveying that complexity in a few minutes while telling jokes can be a challenge.4. What does Paul’s studies of joking about science indicate?A. It may do serious damage to science.B. It can effectively popularize science.C. It totally changes people’s attitude to science.D. It will shift people’s attention from entertainment to science.5. Why do TV watchers receive a little science information?A. Because they enjoy watching entertainments.B. Because science is not easy to come up with.C. Because they find no interest in science issues.D. Because science is scarcely seen on mainstream media.6. What do we know about the late-night shows involving science?A. The hosts get used to playing tricks on scientists.B. The hosts’ aim is to build a positive image of science.C. Education gap can be bridged through late-night shows.D. Science participation can be promoted among their viewers.7. What’s the author’s attitude towards combining science with satire?A. Critical.B. Objective.C. Positive.D. Negative.CThe China International Search and Rescue Team(CISAR) was formed in 2001 and is now made up of several hundred rescue workers and about 20 police dogs. The team brings help and hope to those whose lives are changed by astorm, flood, earthquake, or any other natural disasters.After long and careful training, the team went on its first international rescue tasks in 2003. That year, the Chinese team helped save lives after earthquakes inAlgeriaandIran. It was the first time that a Chinese team had worked outsideChinawhose members won high praise for bravery and skill.Since then, the CISAR has completed many tasks. The list of people to whom help has been given is long. The team treated more than 3,000 people who were wounded in the 2006 earthquake inIndonesia, helped 2,500 wounded people after the earthquake that hitHaitiin 2010, and spent several months giving aid to over 25,000 people suffering from the 2010 floods inPakistan. On April 26, 2015, a group of 62 people from CISAR went toNepalafter the 8.1 magnitude earthquake that happened there.Rescue workers are trained to find people, treat wounds, and hand out food, water, and other supplies. They have to be able to do work that is difficult under conditions which can be very dangerous. After a disaster, there is usually no electricity or water, and there may be diseases and other dangers. Rescue workers get to save lives, but they must also bury the dead. That means they have to be strong in both body and mind.Rescue workers must have big hearts, too. It takes a lot of love and courage to risk one’s own life to save someone else’s. The members of the CISAR have plenty of both and are always ready to go wherever help isneeded.8. What is the function of the numbers in Paragraph 3?A. To advertise for the CISAR.B. To add some basic information.C. To praise Recue Workers’ contributions.D. To stress the dangers Rescue Workers face.9. What is the author’s attitude towards Rescue Workers?A. Hopeful.B. Respectful.C. Curious.D. Supportive.10. What are the last two paragraphs mainly about?A. The duty rescue workers must perform.B. The qualities rescue workers must own.C. The difficulties rescue workers must go through.D. The willingness rescue workers should require.11. What may be the best title of the passage?A. China to the RescueB. How to train CISARC. Welcome to CISARD. Rescue on requestDMost teenagers are still trying to find their passion and purposes in life. However, not Gitanjali Rao. The 15-year-old girl has been coming up with innovative solutions to worldwide problems since she was ten. It is, therefore, not surprising that the teenager has won the honor of “America's Top Young Scientist”.In the third grade, Rao was inspired to build a device after witnessing the shocking story unfold in Flint, Michigan, where cost-cutting measures led to the use of a polluted river as the city's primary water supply and incredibly high levels of lead made their way into people's drinking water.After two months' research, Rao designed a small and portable device that used sensors to instantly detect lead in water. Called Tethys, after the Greek Goddess(女神) of freshwater, it attaches to a cellphone and informs the residents via an app if their drinking water contains lead. The design earned her the 3M Young Scientist Challenge in 2017. She is currently working with scientists and medical professionals to test Tethys' potential and hopes the device will be ready for commercial use by 2022.Later, Rao took on another social issue-drug addiction. Her app, called Epione, which won the Health PillarPrize at the TCS Ignite Innovation Student Challenge in May 2019, is designed to catch drug addiction in young adults before it's too late.More recently, the teenager has developed an app named Kindly, which usesartificial intelligence technology to detect possible signs of cyberbullying(网上欺凌). When users type in a word or phrase, Kindly is able to pick it up if it's bullying, and then it gives the option to edit it or send it the way it is. It gives them the chance to rethink what they are saying so that they know what to do next time.All kinds of awesome, Gitanjali Rao has been selected from 5,000 equally impressive nominees(被提名人) for TIME Magazine's first-ever “Kid of the Year”.12. What gave Rao the idea of inventing the device Tethys?A. The incident of lead pollution.B. The issue with drug addiction.C. The shortage of water supplies.D. The high cost of purifying water.13. What is Rao expecting of Tethys?A. It'll remove metal from water.B. It'll make it to market soon.C. It'll win her a higher prize.D. It'll be fitted to cellphones.14. What will Kindly allow users to do?A. Receive pre-warning signals of threat.B. Input words into a computer automatically.C. Choose from secure social networking sites.D. Weigh their words before posting them online.15. Which of the following can best describe Gitanjali Rao as a young scientist?A. Ambitious and humble.B. Optimistic and adventurous.C. Talkative and outstanding.D. Creative and productive.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
2021年上海飞翔日本人补习中心高三英语第一次联考试题及参考答案
2021年上海飞翔日本人补习中心高三英语第一次联考试题及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at homewith her parents. But through working as a part-time skating instructor and restaurant server, she isn't able to earn enough to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of young adults who have been moving back in with their parents — or never leaving home in the first place — has been growing steadily.UBS Financial Services released a report that even suggests one reason for the growing number of young adultsstill living at home could be that their family doesn't want them to leave.The report shows that 74 percent of millennials (千禧一代)get some kind of financial support from their parents after college. It finds that millennials have redefined the ties that connect parents and children. Millennials see their parents as peers,friends and instructors. Nearly three quarters talked with their parents more than once a week during college. In return, their parents happily provide financial support well into adulthood, helping fund everything for them.Stuart Hoffman, chief economist for the PNC Financial Services Group in theUS, said the number of young adults striking out on their own fell during the Great Recession. Although job growth for millennials since 2014 has improved, that doesn't necessarily mean that millennials are starting to fly the nest. He said, “They may like living at home and being able to save money.“ There's no doubt it has held back household formation and purchases of things people spend money on related to household formation and perhaps related to child-raising," Hoffman explained. "But they are probably traveling more and eating out more if they don't have a house expense or marriage. I don't know if it represents a change in moral values. But it's much more common for adult children to live in their parents’ homes because it's becoming part of the culture.1. What can we learn from the UBS Financial Services' report?A. Millennials are on good terms with their parents.B. Millennials are financially independent after college.C. Parents are unwilling to give their young adults allowance.D. Parents want their kids to stay with them forever.2. What does Hoffman think of young adults' living at home?A. It increases the consumption of household products.B. It may continue despite job growth.C. It is a sign of shift in moral values.D. It is new in American culture.3. What is the author's purpose of writing this passage?A. To introduce millennials' living habits.B. To stress the importance of financial independence.C. To explain why American young adults still live at home.D. To inform people of a social trend in theUS.BDid you know that the average child has heard the word "no" over 20,000 times before they turn the age of three? Ironically, it is also around this time that children begin to develop enough personal character to refuse to obey. The "terrible twos" are categorized by a lack of understanding. Somewhere between three and four, children begin to acquire the skills to reason. It is during this time they watch how other children and adults reason. If we're not careful, the children will watch us model a world of "NOs".By the time a person turns eighteen, how many times have they been told no? I haven't found any studies that even attempted to track this statistic, but I'm sure if the number is 20,000 by three, then at eighteen that number has multiplied. You can do the math.Anyway, I think I know why we say no. We say no to protect. We say no to direct. We say no to stop potential confusion. However, do we sometimes say no just for the sake of saying no? Do we say no because we have internalized(内在化)all of the "NOs" we've heard over the years and we feel it is finally our time to say no to someone else?The internalized no can damage the growth process of dreams in infancy as quickly as it can weaken a three-year-old. And we wonder why we run intopeople with big, un-accomplished dreams who have a bit of a chip on their shoulder. They have to take on the 20,000 NOs. However, the thing that keeps them going is the possibility of the power of ONE YES! Just as it only takes one book to make a writer a Pulitzer Prize Winner, it only takes one word to change the course of your day. That word is YES!4. What do we know about two- year- olds?A. They understand well.B. They often say no to others.C. They think logically.D. They don't do all they're told.5. What effect does saying no have on children?A. They lose all their dreams.B. They aren't easy to succeed.C. They don't make mistakes.D. They never say yes to others.6. Which word best describes the author's attitude to a world of "NOs"?A. Tolerant.B. Disapproving.C. Favorable.D. Carefree.7. What is the text?A. A how-to guide.B. A survey report.C. An opinion essay.D. A short story.CThe prevalence of melanoma (黑素瘤) has been rapidly rising around the world for nearly a century. While some of the increase may be due to better detection, researchers also believe it’s because we’re spending more time outdoors in the sun, vacationing to warmer climates during the winter and using tanning beds. That rise is concerning, since melanoma is the most dangerous kind of skin cancer.Most of us know to cover up and apply sunscreen on hot, sunny days, but when fall arrives, we tend to drop those habits. Experts warn that’s a mistake. Though there’s less need for sun protection after summer ends, exposure to UV rays still adds up.What precautions you should take to defend against melanoma during the cooler months depends on where you are in the world. That’s because the further away you are from the equator, the more UV rays weaken in the winter. “In southern England or Canada, the daily dose of UVA on a clear summer day is 6.5 times higher than on a clear winter day,” says Professor Brian Diffey of the British Association of Dermatologists. “People in those countries typically receive only about 5% of their annual UV exposure in the winter months.”But no matter where you are, even during colder, lower risk months, it’s a mistake to put your sun-protection habits on ice. “It’s important to wear sun-screen when there is a lot of glare from the snow,” says Victoria Mar, director of the Victorian Melanoma Service at Alfred Hospital in Melbourne, Australia.Finally, you should monitor your moles(痣). “Early detection of melanoma is vital for successful treatment,” says Diffey. If it’s caught before it spreads to other parts of the body, the patient will have 99 % of chance to survive for five years. If it’s caught late, that can drop to 25%. Warning signs are a mole that’s changing size, shapeor colour, or one that’s asymmetrical — sometimes referred to as “ugly duckling” moles. If you have concerns, talk to your doctor.8. What’s the main cause of the rise ofmelanoma?A. The climate change.B. Better detection.C. More exposure to the sun.D. The increase ofskin cancer.9.What’s a mistake according to experts?A. Applying sunscreen in summer.B. Wearing sun-screen when there is snow.C. Using sunscreen during lower risk months.D. Dropping sun-protection habits in winter.10. What can we learn from the last paragraph?A. Prevention is better than cure.B. Health is better than wealth.C. A disease known is half cured.D. When the sun comes in, the doctor comes out.11. What is the best title of the text?A. Detect Melanoma.B. Beware Winter Rays.C. Monitor Your Moles.D. Spend Less Time Outdoors.DChinese archaeologists(考古学家)announced on Saturday that some new major discoveries have been made at the Sanxingdui Ruins site in Southwest China, helping uncover another start of the Chinese civilization.Archaeologists have found six new sacrificial pits(祭祀坑)and unearthed more than 500 treasures dating back 3,000 years at the Sanxingdui Ruins in Sichuan Province. So far, archaeologists have unearthed masses of important cultural items from four of the pits, including pieces of gold masks, gold foil, bronze(青铜)masks, bronze trees and large numbers of ivories. The rest of the newly discovered pits arc still being dug up.“Surprisingly, we have unearthed some never — heard — of — before bronze items," said Lei Yu, from the Sichuan Archaeology Research Institute. 'Tor instance, some large and well-made bronze items have strange-looking dragon or cow designs on them.”In another major discovery, relics of silk products were found for the first time at Sanxingdui, which shows “the ancient Shu Kingdom was one of the important starts of silk in ancient China" according to Tang Fei, head ofthe digging team.The new pits sit next to two sacrificial pits discovered in 1986, with areas ranging between 3o square meters and 19 square meters. Together they form an area in which people of the ancient Shu civilization held ceremonies to offer sacrifices to heaven, earth and their forefathers, and prayed for good luck and peace.The Sanxingdui Ruins is regarded as one of the greatest archaeological finds of mankind in the 20th century. The site was accidentally discovered by a farmer in the 1920s. The ruins are located in the city ofGuanghan, about 60 kilometers fromChengduand are believed to be the relics of theShuKingdom.12.

1 Intelligent flight controllers for helicopter control1)A methodology for design of an intelligent helicopter flight controller is presented in this paper. 2)The methodology combines artificial neural network, genetic algorithms, conventional PID-controllers, and fuzzy logic algorithms in the design procedure.3) In this approach, the design of an intelligent controller is based on experimental data collected from actual helicopter flight and not based on analytical models.4) A neural network is trained to learn the dynamic characteristics of the helicopter. 5)Based on the neural model, the coefficients of a PID-controller used for blade angle control are searched for using genetic algorithms. 6)The main rotor speed controller is designed using fuzzy logic algorithm based on knowledge generated from understanding the aerodynamic theory and analyzing the helicopter experimental flight data. 7)The intelligent helicopter flight controller is formed by combining the blade angle PID-controller and the rotor speed fuzzy controller. 8)Simulation results showed that for desired altitude input H d, the intelligent controller was able to generate proper control signals for both the blade angle control and the rotor speed control. 9)The helicopter model altitude output H t follows the desired altitude input H d. 10)The design procedures, theoretical background, results and conclusions are presented in this paper2. EDFA gain modeling using Pspice and neural networks1)A new methodology in modeling the performance of an Erbium Doped Fiber Amplifier (EDFA) Gain is presented in this dissertation. 2)It is based on the gain characteristics of an EDFA under different input signal power spectra and pump levels. 3)The novelty of this dissertation is based on the training and use of a neural network applied to the performance characteristics of an EDFA.;The modeling is divided in two sections. 4)The first model is an electrical equivalent circuit of an EDFA that can be simulated and analyzed by Pspice, a commercial electrical simulation program from OrCad. 5)The second section is the development and implementation of a Neural Network to model the gain response of the EDFA for a given number of input power spectra.;6)In order to provide data and verify the performance of both models, a simulation program was developed. 7)The simulation program's output performance was verified using an EDFA analysis program called Oasix.;8)The results from both models were accurate with respect to the theoretical and experimental data. 9)The electrical equivalent model's output spectrum was proven to match the output of the simulation program. 10)The neural network was trained successfully to identify the EDFA gain spectra to its correspondent input spectrum and pump power level with an accuracy of 98%.4、Characterization and Modeling of the Power Insulated Gate Bipolar T ransistor.The power Insulated Gate Bipolar Transistor (IGBT) is a new switching device designed to overcome the high on-state loss of the power MOSFET. The IGBT behaves as a bipolar transistor which is supplied base current by a MOSFET. The bipolar transistor of the IGBT has a wide base with the base contact at the collector edge of the base and is operated with its base in high-level injection. Because of this, the traditional bipolar transistor models are not adequate for the IGBT and the new model developed in this dissertation must be used. The new model is developedusing ambipolar transport and does not assume the quasi-static condition for the transient analysis.;The new IGBT model is used to describe measurements for extracting the essential physical device parameters of the model. With these extracted parameters, the new IGBT model consistently describes the measured electrical characteristics of IGBTs with different base lifetimes. The important electrical characteristics of the IGBT are the on-state I-V characteristics, the steady-state saturation current, and the switching transient current and voltage waveforms. The transient waveforms are examined in detail for constant anode voltage switching, clamped inductive load switching, and series resistor, inductor load switching.;The disadvantage of the IGBT is its slow turn-off speed relative to that of the power MOSFET. The two methods which have been proposed to reduce the turn-off time of the IGBT are base lifetime reduction and buffer layer inclusion. Both methods have the disadvantage, though, of also increasing the on-state voltage. The buffer layer is a high-doped portion of the bipolar transistor base at the base-emitter junction. The new IGBT model discussed above is extended to include the buffer layer. Using the extended model, it is shown that the buffer layer IGBT can be made to have a faster switching time for a given on-state voltage than that of the nonbuffer layer (lifetime reduction) IGBT.;In summary, a new model is developed for the IGBT. It is shown that the new model must be used to accurately describe the steady-state and transient characteristics of the IGBT. The model is used to compare the effects of lifetime reduction and buffer layer inclusion. The results of the comparison show that a better on-state voltage, switching speed trade-off is obtained using the buffer layer than is obtained using lifetime reduction.5、Developing modeling and simulation methodology for virtual prototype power supply systemThis dissertation develops a modeling and simulation methodology for design, verification, and testing (DVT) power supply system using a virtual prototype. The virtual prototype is implemented before the hardware prototyping to detect most of the design errors and circuit deficiencies that occur in the later stage of a standard hardware design verification and testing procedure. The design iterations and product cost are reduced significantly by using this approach. ^ The proposed modeling and simulation methodology consists of four major parts: system partitioning, multi-level modeling of device/function block, hierarchical test sequence, and multi-level simulation. By applying the proposed methodology, the designer can use the virtual prototype effectively by keeping a short simulation CPU time as well as catching most of the design problems. ^ The proposed virtual prototype DVT procedure is demonstrated by simulating a 5 V power supply system with a main power supply, a bias power supply, and other protection, monitoring circuitry. The total CPU time is about 8 hours for 780 tests that include the basic function test, steady stage analysis, small-signal stability analysis, large-signal transient analysis, subsystem interaction test, and system interaction test. By comparing the simulation results with the measurements, it shows that the virtual prototype can represent the important behavior of the power supply system accurately. Since the proposed virtual prototype DVT procedure verifies the circuit design with different types of the tests over different line and load conditions, many circuit problems that are not obvious in the original circuit design can be detected by the simulation. ^ The developed virtual prototype DVT procedure is not only capable of detecting most of the design errors, but also plays an important role in design modifications. This dissertation also demonstrates how to analyze the anomalies of the forward converter with active-clamp reset circuit extensively and facilitate the design and improve the circuitperformances by utilizing the virtual prototype. With the help of the virtual prototype, it is the first time that the designer is able to analyze the dynamic behavior of the active-clamp forward converter during large-signal transient and optimize the design correspondingly.7、Adaptive nonlinear control of spacecraftThe problem of spacecraft attitude control and momentum management is addressed using nonlinear controllers based on feedback linearization. A chief limitation of the feedback linearization technique is that it requires an exact cancellation of nonlinear terms in order to obtain linear input-output behavior. Adaptive nonlinear controllers for linearizable systems are investigated to overcome this restriction and to achieve asymptotic linear behavior.The spacecraft attitude control and momentum mangement model is characterized by having uncertain parameters appearing linearly on both sides of the dynamicl equation. Therefore,two adaptive controf laws are developed forgeneral models in which the parameters appear linearly on both sides of the dynamical equations.The spacecraft attitude control and momentum mangement problem is then addressed with the adaptive nonlineu control laws utilized and uncertainties in the spacecraft principal intertias assumed. The adaptive nonlinear approach is shown to effectively control the Space Station attitude and effector momentum, while providing accurate estimates of inertias. The combined tracking prediction-error based tracking is shown to have improvement over the performance of the tracking-error based adaptive controller.8、Discrete-Time Control of A Spacecraft with Retargetable Flexible Antennas.This dissertation considers the discrete-time control of a spacecraft consisting of a rigid-platform. with retargetable flexible antennas. The mission consists of independent minimum-time maneuvers of each antenna to coincide with predetermined lines of sight, while the platform. is stabilized in an inertial space and elastic vibration of the antennas is suppressed. The system is governed by a set of linearized, time-varying equations of motion. A discrete-time approach permits consideration of the time-varying nature of the system in designing the control law.;Both global and decentralized controls are proposed for a noise-free system with full-state feedback. Initially, a time-varying linear-quadratic regulator (LQR) is implemented, followed by two types of decentralized controllers. First, a collocated control law is devised in which actuator forces are based on the position and velocity at the actuator locations. Next, a new metho d called Substructure-Decentralized Control is proposed, where each flexible substructure is controlled based on state measurements associated with the substructure modes of the separately modeled appendages.;In both global and decentralized cases, a linear control law is first implemented coupled with an open-loop disturbance-accommodating control based on the known inertial disturbances caused by the maneuver. Elastic motion is next controlled using nonlinear (on-off) antenna controllers for each decentralized case. For Substructure-Decentralized Control, the controls translate into quantized actual controls. Lastly, nonlinear (on-off) control laws are also used to control the rigid-body motion for each case.;Next, the problem of controlling the time-varying system in the presence of noisy actuators and sensors is examined. It is assumed that only displacements, not velocities, are sensed for both rigid-body and elastic motion, making state reconstruction also necessary. A discrete-time, full-order Kalman filter is constructed for the time-varying system. A pseudo-decentralized control is proposed whereby feedback controls are based on system state estimates. As before, both linear and nonlinear controls are implemented. For each case mentioned, a numerical example is presented involving a spacecraft with a singleflexible maneuvering antenna.。
