Back To The Future Feedback
Feedback control(反馈控制) 外文翻译
Feedback controlThe class of control problems to examined here is considerable engineering interest. We should consider systems with several input , some known as controls because they may be manipulated and others called external disturbances, which are quite unpredictable, For example , in an industrial furnace we may consider the fuel flow, the ambient temperature, and the loading of material into the furnace to be inputs . Of there , the fuel flow is accessible and can readily be controlled , While the latter two are usually unpredictable disturbances.In such situation , one aspect of the control problem is to determine how the controls should be manipulated so as to counteract the effects of the external disturbances on the state of the system . One possible approach to the solution of this problem is to use a continuous measurement of the disturbances, and from this and the known system equations to determine what the control inputs should be as functions of time to give appropriate control of the system state.A different approach is to construct a feedback system , that is , rather than measure the disturbances directly and then compute their effects on the system from the model or system equations , we compare direct and continuous measurements of the accessible system states with signals representing their “ desired values” to dorm an error signal , and use this signal to produce inputs to the system which will drive the erroras close to zero as possible .By some abuse of terminology , the former approach has come to be known as open loop control , and the tatter as closed-loop control .At first sight , the two approaches might appear to be essentially equivalent . Indeed, one might surmise that an open-loopControl scheme is preferable since it is not necessary to wait until the disturbances have produced an undesirable change in the system state before corrective inputs can be computed and applied.图27．1（a）图27.1(b)However, this advantage is more than outweighed by the disadvantages of open-loop control and the inherent advantages of feedback systems. First, in many cases the implementation of theopen-loop control suggested above would require a very sophisticated (and hence expensive)computing device to determine the inputs require to counteract the predicted disturbance effects. Second, a feedback system turns out to be inherently far less sensitive to the accuracy with which a mathematical model of the system has been determined. Put another way, a properly designed feedback system will still operate satisfactorily even when the internal properties of the system change by significant amounts.Another major advantage of the feedback approach is that by placing a “feedback loop” around a system which initially has quite unsatisfactory performance characteristics, one can in many case construct a system with satisfactory behavior. Consider, for example, a rocket in vertical flight. This is essentially an inverted pendulum, balancing on the gas jet produced by the engine, and inherently unstable(any deviation of the rocket axis from the vertical will cause the rocket to topple over). It can, however, be kept stable in vertical flight by appropriate changes in the direction of the direction of the exhaust jet, which may be achieving these variations in jet direction is to use a feedback strategy in which continuous planes cause a controller to make appropriate adjustments to the direction of the rocket engine. Stabilization of an inherently unstable system could not be achieved in practice by an open-loop control strategy.The mathematical tools required for the analysis and design offeedback system differ according to the structural complexity of the systems to be controlled and according to the objectives the feedback control is meant to achieve.In the simplest situation, one control a single plant state variable, called the output, by means of adjustments to a single plant input. The problem is to design a feedback loop around the system which will ensure that the output changes in response to certain specified time functions or trajectories with an acceptable degree of accuracy. In either case, the transients which are inevitably excited should not b e too “violent” or persist for too long.In a typical situation,, The problem is to design a feedback system around the plant consisting of (a) a device which produces a continuous measurement Ym of the output; (b) a comparator in which this signal is subtracted from a reference input(or set point, or desired output)Yr , representing the desired value of the output, to produce an error signal e; and(c)a controller which uses the error signal e to produce an appropriate input u to the plant. We shall call this configuration a single-loop feedback system, s term which is meant to convey the essential feature that just one of the plant states (the output y)is to be controlled using only one input. The objective of the feedback system is to make the output Y(t) follow its desired value Yr(t) as closely as possible even in the presence of nonzero disturbances d(t). The ability of a system to do so understeady-state condition is known as static accuracy.图27.2Frequently Yr is a constant , in which case we call the feedback system a regulator system. An example is the speed control system of a turbine-generator set in a power station, whose main purpose is to maintain the generator speed as nearly constant as possible. Sometimes Yr is a prescribed non-constant function of time, such as a ramp function;An example of this would be the control system for a radar antenna whose axis is to be kept aligned with the line of sight to an aircraft flying past with constant angular velocity, In this case, we refer to the system as a tracking system..Single-loop feedback systems with the structure of Fig.27.2 are often called servomechanisms because the controller usually includes a device giving considerable power amplification. For instance, in the control system of a hydroelectric turbine-generator set, the signals representing measured speed and desired speed might be voltages at a power level of milliwatts, while several hundred horsepower might be required tooperate the main turbine valve regulating the water flow. This example also illustrate an important engineering constraint in the design of feedback control system. In many applications, the plant and the activating device immediately preceding it operate at comparatively high power levels, and their dynamic properties, if unsatisfactory for some reason, can be changed only at the expense of a feedback system is preferably done in the low-power components of the feedback system, I,e., in the measuring elements and the controller。

电影回馈英文作文
电影回馈英文作文英文：Movie feedback is an important aspect of the film industry. As a movie enthusiast, I find it necessary to provide feedback on the movies I watch. Movie feedback can be positive or negative, but it is important to provide constructive criticism to help filmmakers improve their craft.When it comes to positive feedback, I usually focus on the aspects of the movie that I enjoyed the most. For example, I might praise the cinematography, the acting, or the storyline. I also like to mention any standout performances by the actors or actresses in the movie. Positive feedback is important because it can encourage filmmakers to continue making great movies.On the other hand, negative feedback can be just as important. When I provide negative feedback, I try to bespecific about what I did not like about the movie. For example, I might criticize the pacing of the movie, the dialogue, or the special effects. It is important to provide constructive criticism so that filmmakers can use the feedback to improve their future movies.Overall, movie feedback is important for both filmmakers and moviegoers. As a movie enthusiast, I find it necessary to provide feedback on the movies I watch. Whether positive or negative, feedback can help improve the quality of movies and make the film industry better.中文：电影反馈是电影行业的重要方面。

She isn’t a girl I am fond of (喜欢)!”“Why not?”“She never talks to me!”Dad sighed and moved down the aisle (过道). “Lucy is a new girl in class. She doesn’t know a single person in the school. Your party will be a great chance for her to get to know everyone.”“No, it won’t. She will probably sit in the corner and not talk to anyone. Every day at lunch she sits all by herself. She wants to eat alone!” Madison shrugged (耸肩) and rolled her eyes. “Madison, I’m done discussing this. You will invite every girl in your class, including Lucy Gilbert!”On Saturday morning, the family blew up balloons, decorating (装饰) the house cheerfully. Madison was dressed beautifully for the day, wearing her new blue dress. She usually wore sports clothes because she loved to be outside riding her horse Star with a lead rope.Madison greeted her friends in the doorway, picturing various presents her friends would bring her. In the meanwhile, she was wondering whether Lucy would destroy the party if she came. Anyhow, all the girls she invited came finally, including Lucy.The girls had a fantastic time by singing and dancing while Lucy sat in the corner silently alone. Later, all the girls gathered around the table as Madison opened her presents. Opening them one by one, Madison thanked her friends, with a bright smile on her face.Lucy’s present was the very last to be opened. Inside the box was a hand-made lead rope. Shocked, she looked up at Lucy.“It’s a lead rope for your horse Star. I made it myself!”Madison pulled it out of the box and placed it on her lap (大腿上), amazed at its beauty.Lucy added, “I heard you talking about your horse at school. That’s when I got the idea to make you a lead rope.”Deeply moved by Lucy’s words, Madison held the lead rope tightly. It was her favourite birthday present of the day. With mixed feelings, Madison tried hard to fight the tears building in her eyes.“Thanks so much for this lead rope. I love it! Would you like to join us and be our friends?” Lucy nodded cheerfully and joined the other girls to enjoy the party.24．Why did Madison invite Lucy to her party?A．Lucy was her best friend.B．Lucy liked to talk to others.C．Madison’s dad asked her to do that.D．Madison wanted to invite every girl in her class.25．When Madison opened Lucy’s present, she felt ________.A．surprised B．relaxed C．nervous D．terrible 26．What can we learn from the story?A．Friendship is the greatest pleasure in life.B．It’s necessary to learn to accept people around you.C．It’s important to decorate the house before the party.D．It’s OK for kids to go to a birthday party with presents.If we want to grow as people, we can’t just depend on our own evaluation (评价) of howwe’re doing. We also need to know what other people think about our performance. Receiving feedback (反馈) from others can help us see the larger picture and show us a way forward to success.However, someone has to give that feedback, and sometimes, that someone will be you. How should you deal with this?First things first, if you notice a situation in which some feedback would be helpful, give it as soon as you can. If you wait until the matter disappears from the person’s mind, they might not understand what you’re trying to tell them. Take the person to a safe, comfortable place and offer your advice in private.When you’re giving feedback, it’s important to keep in mind that no one likes to be told they’re doing a bad job. Make sure you give an equal ( 相等的) amount of good feedback to balance out anything bad. Like the saying goes, “A spoonful of sugar helps the medicine go down. ”All good feedback shares something in common. First, it should help achieve a goal. It’s less useful to tell your friends that their dish tastes “interesting” than it is to suggest adding a little salt. Feedback should also look toward the future. You can’t change what’s already happened, but you can prevent it from happening again. Tell your friends they should take more notes in class instead of talking about how they should have studied harder for the big history exam they failed.Finally, don’t think your suggestion is the only correct way to deal with a situation. You might even end up with some feedback on your feedback. Don’t take it personally—it can only help you give better advice next time.27．Why is it important to give feedback in time?A．You might forget to tell the person later on.B．Perhaps the person wants the feedback right away.C．The person might forget what happened at that time.D．Maybe the person needs time to understand your advice.28．Which of the following is TRUE according to the passage?A．Good feedback would help you achieve a goal.B．Giving feedback can help us see the larger picture.C．You can give your feedback at any time or any places.D．Good feedback is the best way to deal with a bad situation.29．What is the passage mainly about?A．How to give feedback properly.B．Common things in good feedback.C．How to find a way forward to success.D．Differences between good and bad feedback.Floods, droughts (干旱), storms, heat waves…extreme weather (极端天气) is becoming more and more common all over the world.It’s a fact that this is caused by greenhouse gas emissions (温室气体排放) from human activities, a report said, according to China Daily.Many people suffered from extreme weather last summer. Areas of Europe were hit by big thunderstorms (雷雨). At least 13 people died in Austria, France and Italy. In Portugal and Spain, huge wildfires forced thousands to leave their homes.In the US, more than 80 percent of the west was in drought, up from just 20 percent in 2021. Three-quarters of farmers in drought-hit areas stopped growing food.In China, the heat affected the south seriously. The duration of last year’s high temperatures broke the 62-day record in 2013, becoming the longest heat wave in 61 years.Extreme weather events are not only killing people and destroying homes. They also drive more people into hunger. Millions in East Africa have little food to eat today, according to the World Health Organization. For four years, there wasn’t enough rain during its rainy seasons and the land was too dry to grow food.Extreme weather has also made 218 of the known 375 infectious diseases (传染) more serious according to the journal, Nature Climate Change. As viruses (病毒) try to adapt to (适应) higher temperatures, they gradually become stronger and harder to kill.Extreme weather is a warning to us. It’s time for everyone to take action to slow down climate change. We can drive less, plant trees, save water, buy less plastic and do lots of other things, too. Here is an example of saving water from Australia.In Australia, there are different levels of water restrictions (限制) during really dry summers. They ban (禁止) or limit the use of water for outdoor purposes. In some states, they are “permanent (永久的)” .One restriction is to only water the garden on certain days and at certain times. Watering in the evenings saves water because the sun is less strong and stops the water fromevaporating (蒸发) so quickly. The same goes for washing cars. If people break the rules, they’ll face a fine.Apart from official (官方的) restrictions, people are also encouraged to save water in other ways, like by taking shorter showers. They could even buy a special two-minute egg timer and stick it on the shower wall to remind them when their shower time is up. Two minutes seems short at first, but once you get used to it, it’s enough.30．The word “duration” in Paragraph 5 probably means “_______”.A．influence B．whole period C．challenge D．main reason 31．What effects does extreme weather have on the earth?A．It caused greenhouse gas emissions.B．It made some infectious diseases more serious.C．It made millions in Europe have little food to eat.D．It made more than 80 percent of Africa into drought.32．What do Australians do to save water during dry summers?A．They are encouraged to wash cars in the afternoon.B．They start to reduce the number of flowers in the garden.C．They are forced to buy a special timer to take shorter showers.D．They can only water their gardens on certain days and at certain times.33．What is the writer’s main purpose in writing this passage?A．To discuss how to save the planet.B．To explain what extreme weather is.C．To draw people’s attention to extreme weather.D．To compare different extreme weather conditions.五、阅读回答问题Learning a Foreign LanguageThere are many aspects (方面) to language learning, such as how words are said, which words are chosen and what forms of words are used. All of these aspects together can make learning a foreign language difficult. But some advice might make learning a new language easier and more fun.Don’t worry too much about pronouncing words the wrong way.Pronunciation is important, of course. It helps listeners to understand what someone says more clearly. But the most important step in learning a new language is to practice speaking it. As for learning any new skill, practice makes perfect. And most of the time, the native (本地的) speaker is glad to help improve the pronunciation of the words.Don’t be afraid to guess the meaning of what someone says.There are tens of thousands of words in English. It is impossible to know all of them. You may use context (上下文) and body language to guess what others say. For example, when a person says “Hola” and waves his hand, one might guess that the person is giving a greeting. Whether it means “Hello” or “Good morning”, it is not necessarily important at that moment to know the exact meaning.Don’t give up.Learning a new language or skill always takes time.

高三英语未来发展预测练习题30题
高三英语未来发展预测练习题30题1<背景文章>In recent years, artificial intelligence (AI) has been making significant progress and is expected to have a profound impact on various fields, including education. As we look to the future, the role of AI in education is becoming increasingly important.AI-powered tutoring systems can provide personalized learning experiences for students. By analyzing a student's learning style, strengths, and weaknesses, these systems can tailor educational content to meet the specific needs of each individual. For example, if a student struggles with a particular concept, the AI tutor can provide additional explanations and practice exercises until the student masters the concept.Moreover, AI can also be used to grade assignments and provide feedback to students. This not only saves teachers time but also allows for more timely and detailed feedback. Students can receive immediate feedback on their work, which can help them identify areas for improvement and make necessary adjustments.Another area where AI is likely to have a major impact is in adaptive learning. Adaptive learning platforms can adjust the difficulty level of the content based on a student's performance. If a student is finding thematerial too easy or too difficult, the platform can automatically adjust the level to ensure that the student is challenged but not overwhelmed.However, the integration of AI in education also raises some concerns. One concern is the potential for job displacement of teachers. As AI takes on more tasks traditionally performed by teachers, there is a fear that some teachers may lose their jobs. Another concern is the ethical implications of using AI in education. For example, there is a need to ensure that student data is protected and used appropriately.Despite these concerns, it is clear that AI has the potential to revolutionize education. By providing personalized learning experiences, timely feedback, and adaptive learning, AI can help students learn more effectively and efficiently.1. What can AI-powered tutoring systems do?A. Provide standardized learning experiences.B. Ignore a student's weaknesses.C. Tailor educational content to students' needs.D. Replace teachers completely.答案：C。
未来取向的记分方法
未来取向的记分方法English Answer:Future-oriented scoring methods are assessment techniques that emphasize the potential and future growthof students rather than their current academic performance. These methods are designed to encourage a growth mindset in students and promote their development of essential skills and knowledge for success in future academic, career, andlife endeavors.There are various types of future-oriented scoring methods, each with its own unique approach to assessing student growth. Below is a brief overview of some common types:1. Growth Portfolios: Growth portfolios are collections of student work that demonstrate their progress and growth over time. Students are encouraged to reflect on their work, identify areas for improvement, and set goals for futurelearning. By examining the portfolio as a whole, educators can gain insights into a student's overall development and trajectory.2. Goal Setting and Tracking: This method involves setting individualized goals for each student. The goals should be challenging yet attainable and aligned with the student's strengths and aspirations. Students track their progress towards these goals through regular self-assessments and feedback from the teacher. This approach fosters student ownership of their learning and encourages them to take an active role in their own development.3. Authentic Assessments: Authentic assessments evaluate students' knowledge and skills in real-world contexts. They are designed to reflect the types of tasks and challenges that students will encounter in their future lives. By focusing on the application of skills in meaningful settings, authentic assessments provide a richer and more holistic view of student learning.4. Formative Assessments: Formative assessments areconducted during the learning process to provide students with feedback and support. They are typically low-stakes and designed to help students identify areas where they need additional support. By providing timely and actionable feedback, formative assessments promote student self-regulation and facilitate targeted interventions to support student growth.5. Self-Assessment and Peer Feedback: Self-assessment and peer feedback involve students reflecting on their own work and providing feedback to their peers. Theseactivities encourage students to develop metacognitive skills, such as self-awareness and critical thinking. By engaging in self-assessment and peer feedback, students learn to identify their strengths and weaknesses, set realistic goals, and seek support when needed.Future-oriented scoring methods offer several key benefits. Firstly, they emphasize student growth and potential rather than solely focusing on current performance. This fosters a positive and supportive learning environment where students feel encouraged to takerisks and learn from their mistakes. Secondly, these methods promote the development of important skills and dispositions, such as self-reflection, goal setting, and perseverance, which are essential for success in college, career, and life. Thirdly, they provide valuable insights into student learning and progress, enabling educators to make informed decisions about instruction and support.中文回答：未来取向的记分方法概述。

客户评价英语作文带翻译Title: Customer Feedback: Importance and Impact。
In today's global marketplace, customer feedback plays a crucial role in shaping businesses and their offerings. Whether positive or negative, customer evaluations provide invaluable insights that can drive product improvements, enhance service quality, and ultimately foster customer satisfaction and loyalty. In this essay, we delve into the significance of customer feedback and its impact on businesses, accompanied by real-life examples and analysis.First and foremost, customer feedback serves as adirect communication channel between businesses and their clientele. By actively soliciting feedback through surveys, reviews, and other means, companies demonstrate their commitment to listening and responding to customer needs and preferences. For instance, online retail giant Amazon regularly prompts customers to rate their purchases and leave reviews, which not only helps future buyers makeinformed decisions but also enables Amazon to refine its product offerings and enhance the overall shopping experience.Moreover, customer feedback acts as a barometer of satisfaction and loyalty. A satisfied customer is more likely to become a repeat customer and advocate for the brand, whereas a dissatisfied customer can quickly spread negative word-of-mouth, potentially damaging the company's reputation. Take the hospitality industry, for example. Hotels and resorts actively seek feedback from guests through post-stay surveys or online review platforms like TripAdvisor. Positive reviews often highlight exceptional service, cleanliness, and amenities, attracting new guests and bolstering the property's reputation. Conversely, negative reviews may point out issues such as rude staff, poor maintenance, or subpar facilities, prompting management to take corrective action to prevent further dissatisfaction.Furthermore, customer feedback serves as a catalyst for innovation and continuous improvement. By analyzingfeedback trends and identifying recurring issues or suggestions, businesses can pinpoint areas for enhancement and innovation. Consider the case of smartphone manufacturers like Apple and Samsung. Through customer feedback channels such as user forums, app reviews, and customer service interactions, these companies gather insights into user preferences, pain points, and feature requests. This feedback informs the development of new product iterations, software updates, and user experience enhancements, ensuring that future releases better align with customer expectations and market demands.Additionally, customer feedback fosters transparency and trust between businesses and their stakeholders. When companies openly invite feedback and demonstrate a willingness to address concerns and implement changes based on customer input, they signal their commitment to accountability and customer-centricity. This transparency not only enhances the company's credibility but also deepens the bond of trust with its customer base. Take the example of food delivery platforms like Uber Eats and DoorDash. These platforms actively encourage customers torate their delivery experiences and provide feedback on order accuracy, delivery speed, and overall satisfaction. By promptly addressing issues such as missing items or late deliveries and offering refunds or credits as compensation, these platforms reinforce their dedication to customer satisfaction and reliability, thereby strengthening customer trust and loyalty.In conclusion, customer feedback is a vital component of business success in today's competitive landscape. From improving product quality and service delivery to fostering customer loyalty and trust, the impact of customer feedback cannot be overstated. By actively soliciting, analyzing, and responding to customer feedback, businesses can gain a competitive edge, drive innovation, and build lasting relationships with their customers. As the adage goes, "The customer is always right," and businesses that prioritize customer feedback are poised to thrive in the dynamic marketplace of tomorrow.标题，客户反馈，重要性与影响。

Back To The Future Feedback
Back To The Future is a movie which mainly talks that the leading character, Marty accidently got on a time machine and back to the past. He came across his young parents and devoted himself to bring his parents together. Nevertheless, any change of the history would cause enormous influence to the destiny of them. Therefore, Marty tried his best to make things right without destroying the history.
After watching this movie, I can’t help but lose in deep thought. It’s so amazing that the main character could travel whenever and wherever he wanted by a time machine. However, in our real life, we can’t have a time machine as Marty. The only thing we can do is to live in present.Sometimes, we may want to back to the moment when you achieved your own success so as to go over the feeling of being honored. Or we may want to back to the time when you did some wrong things such as arguing with your parents, separating with your partner and so on so as to change the bad results. But no matter how desire you are for your honor or how regretful you are for the wrong things, you just can not back to the future. Just as the saying goes, “Life is like a one-way ticket to go without, no rehearsals, each are live”，therefore we should keep “Carpe diem” in mind. If we want a better future, then we should work hard from now on. There is no need for self-pity criticism but try our best to make every minute count.
Generally speaking, this movie is an innovation among eighties movies for the time travel, which certainly excites people’s imagination. But above all, it also reminds us that make each day count instead of daydreaming. Only make full use of present can we create a better future.。
