请你给Susan 写封信,内容应包括:1. 你对她的担忧表示理解;2. 长城的重要性及其在中国历史中的地位;3. 描述一些如何保护长城的措施;4. 倡议大家共同保护长城,确保其美丽与历史价值永久存在。

Dear Susan,I hope this letter finds you well. I understand your concerns about the littering problem on the Great Wall of China. As a Chinese citizen, I share your worries and would like to provide you with some insights on this matter.The Great Wall is not only a magnificent architectural wonder but also a symbol of China's rich history and cultural heritage. It stretches across thousands of kilometers, bearing witness to centuries of Chinese civilization. However, the rapid increase in tourism has brought about some negative consequences, including littering. Many visitors unfortunately do not realize the significance of protecting this historical landmark.To address this issue, various measures have been implemented to preserve the Great Wall. First and foremost, signage has been placed along the wall, reminding tourists to respect the environment and refrain from littering. Additionally, local authorities have stepped up patrols todiscourage any inappropriate behavior. Public campaigns have been launched to raise awareness among both locals and tourists, emphasizing the importance of maintaining the cleanliness of this national treasure.I believe that protecting the Great Wall requires collective efforts from the government, society, and individuals. It is crucial to educate people about the historical and cultural value of the Great Wall, encouraging them to act responsibly during their visits. Furthermore, imposing fines or stricter penalties on those who violate the regulations can serve as a deterrent.Let us join hands in preserving the beauty and historical significance of the Great Wall. Through our combined efforts, we can ensure that this magnificent structure remains intact for future generations to admire and appreciate.Best regards,Li Hua字数:345字。

Young children across the globe enjoy playing games of hide and seek. For them, there’s something highly exciting about 41 someone else’s glance and making oneself unable to be seen.However, we all witness that preschool children are remarkably 42 at hiding. They often cover only their eyes with their hands, leaving the rest of their bodies 43 .For a long time, this ineffective hiding method was 44 as evidence that children are hopelessly “egocentric”(自我中心的) creatures. But our 45 research results in child developmental psychology 46 that idea.We brought young children aged 2-4 into our Minds in Development Lab at USC. Each 47 sat down with an adult who covered her own eyes or 48 . We then asked the child if she could 49 or hear the adult. Surprisingly, children replied that they couldn’t. The same 50 happened when the adult covered her own mouth: 51 children said that they couldn’t 52 to her.A number of 53 ruled out that the children misunderstood what they were being asked. The results were clear: Our young subjects 54 the questions and knew 55 what was asked of them. Their 56 to the questions reflected their true 57 that “I can see you only if you can see me, too.”They simply 58 mutual(相互的) recognition and regard. Our 59 suggest when a child “hides” by putting a blanket over her head, it is not a result of egocentrism. In fact, children consider this method 60 when others use it.41.

I was considering this while working as a 41 just a few weeks ago. And it came to me then how much easier it would be if we had a range of words that express different 42 of gratitude(感谢).My thoughts were soon 43 . We had a woman patient who was 44 from a knee replacement operation. One afternoon, while 45 to get into bed she collapsed(倒下) from what was 46 discovered to be a heart attack. The collapse was disastrous, 47 the emergency medical team and good teamwork. But she recovered, though 48 _, and was ready for discharge(出院) after four weeks.She was 49 for everything that the medical and nursing team had done for her. On her day of discharge, we shared in her 50 at her recovery. As she was 51 she was eager to say 52 to each of us in the nursing team. When she 53 one nurse, she tried to press a five-pound note into her hand. My colleague 54 to accept it, saying that we were all just 55 our job. The patient looked puzzled, and then 56 : “Oh this isn’t for the _57__ I had. I take that as a 58 . No, this is for setting my hair yesterday.”And there you have it. To many people, 59 lives is part of the job but styling hair is an 60 and should be rewarded.41. A. cleaner B. chemist C. nurse D. doctor42. A. grades B. meanings C. needs D. expectations43.

If we __42__ it is a door, they’ll want to go outside __43__. It will drive us crazy. The kids apparently know the __44__. But our insisting it’s __45__ a window has kept them from __46__ millions of requests to open the door.I hate lying to the kids. One day they’ll __47__ and discover that everything they’ve always known about windows is a __48__. I wonder if __49__ should always tell the truth no matter the __50__. I have a very strong __51__ that the lie we’re telling is doing __52__ damage to our children. Windows and doors have __53__ metaphorical (比喻) meanings. I’m telling them they can’t open what they ab solutely know is a door. What if later in __54__ they come to a metaphorical door, like an opportunity of some sort, and __55__ opening the door and taking the opportunity, they just __56__ it and wonder, “What if it isn’t a door?” That is, “What if it isn’t a __57__ opportunity?”Maybe it’s an unreasonable fear. But the __58__ is that I shouldn’t lie to my kids. I should just __59__ repeatedly having to say, “No. We can’t go outside now.” Then when they come to other doors in life, be they real or metaphorical, they won’t __60__ to open them and walk through.41.

The 42 might damage the beauty of the place. The glaciers(冰川) are disappearing, changing the 43 of Kilimanjaro.Hearing these stories, I’m 44 about the place — other destinations are described as “purer” natural experiences.However, I soon 45 that much has changed since the days of disturbing reports of 46 among tons of rubbish. I find a 47 mountain, with toilets at camps and along the paths. The environmental challenges are 48 but the efforts made by the Tanzania National Park Authority seem to be 49 .The best of a Kilimanjaro 50 , in my opinion, is n’t reaching the top. Mountains are 51 as spiritual places by many cultures. This 52 is especially evident on Kilimanjaro as 53 go through five ecosystems(生态系统) in the space of a few kilometers. At the base is a rainforest. It ends abruptly at 3, 000 meters, 54 lands of low growing plants. Further up, the weather 55 — low clouds envelope the mountainsides, which are covered with thick grass. I 56 twelve shades of green from where I stand. Above 4, 000 meters is the highland 57 : gravel(砾石), stones and rocks. 58 you climb into an arctic-like zone with 59 snow and the glaciers that may soon disappear.Does Kilimanjaro 60 its reputation as a crowded mountain with lines of tourists ruining the atmosphere of peace?

I 41 the idea of taking the class because, after all, who doesn’t want to 42 afew dollars? More than that, I’d always wanted to learn chess. And, even if I weren’t43 enough about free credits, news about our 44 was appealing enough to me. He was an international grandmaster, which 45 I would be learning from one of the game’s 46 . I could hardly wait to 47 him.Maurice Ashley was kind and smart, a former graduate returning to teach, and this 48 was no game for him; he meant business. In his introduction, he made it 49 that our credits would be hard-earned. In order to 50 the class among other criteria, we had to write a paper on how we plan to 51 what we would learn in class to our future professions and 52 , to our lives. I managed to get an A in that 53 and learned life lessons that have served me well beyond the 54 .Ten years after my chess class with Ashley, I' m still putting to use what he 55 me: “the absolute most important 56 that you learn when you play chess is how to make good 57 . On every single move you have to 58 a situation, process what your opponent (对手) is doing and 59 the best move from among all your options.” These words still ring true today in my 60 as a journalist.41.

I myself went through this 41 process and found something that has changed my 42 at college for the better: I discovered ASL-American Sign Language(美式手语).I never felt an urge to 43 any sign language before. My entire family is hearing, and so are all my friends. The 44 languages were enough in all my interactions(交往). Little did I know that I would discover my 45 for ASL.The 46 began during my first week at college. I watched as the ASL Club 47 their translation of a song. Both the hand movements and the very 48 of communicating without speaking 49 me. What I saw was completely unlike anything I had experienced in the 50 . This newness just left me 51 more.After that, feeling the need to 52 further, I decided to drop in on one of ASL club’s meetings. I only learned how to 53 the alphabet that day. Yet instead of being discouraged by my 54 progress, I was excited. I then made it a point to 55 those meetings and learn all I could.The following term, I 56 an ASL class. The professor was deaf and any talking was 57 . I soon realized that the silence was not unpleasant. 58 , if there had been any talking, it would have 59 us to learn less.

Then, Larry asked the 57 if he was needed or 58 to go. They let him and the other man go.One thing is 59 --Larry went above and beyond the call of duty by getting so close to the burning vehicle!

On the way, we spotted a man holding a piece of paper that said, “ 41 my job. Family to Feed.”At this store, a 42 like this is not normal. My 10-year-old noticed him and make a 43 on how bad it must be to have to stand 44 in the cold wind.In the store, I asked each of my kids to 45 something they thought our “friend” there would 46 . They got apples,a sandwich and a bottle of juice. Then my 17-year-old suggested giving him a 47 . I thought about it. We were 48 on cash ourselves, but… well, sometimes 49 from our need instead of our abundance is 50 what we need to do! All the kids 51 something they could do away with for the week.When we handed him the bag of 52 , he lit up and thanked us with 53 eyes. When I handed him the gift card, saying he could use it for 54 his family might need, he burst into tears.This has been a wonderful 55 for our family. For days the kids have been looking for others we can 56 ! Things would have played out so 57 if I had simply said, “No, we really don’t have 58 to give more.” Stepping out not only helped a brother in 59 , it also gave my kids the 60 taste of helping others. It’ll go a long way with them.41. A. Lost B. Changed C. Quit D. Finished42. A condition B. place C. sight D. show43. A. suggestion B. comment C. decision D. call44.

As a matter of fact, we can see this 41 at work in people of all 42 . For example, on Christmas morning, children are excited about 43 with their new toys. But their 44 soon wears off and by January those 45 toys can be found put away in the basement. The world is full of 46 stamp albu ms and unfinished models, each standing as a monument to someone’s 47 interest. When parents bring home a pet, their child 48 bathes it and brushes its fur. Within a short time, however, the 49 of caring for the animal is handed over to the parents. Adolescents enter high school with great 50 but are soonlooking forward to 51 . The same is true of the young adults going to college. And then, how many 52 , who now complain (抱怨) about the long drives to work, 53 drove for hours at a time when they first 54 their driver’s license (执照)? Before people retire, they usually 55 to do a lot of 56 things, which they never had 57 to do while working. But 58 after retirement, the golfing, the fishing, the reading and all of the other pastimes become as boring as the jobs they 59 . And, like the child in January, they go searching for new 60 .41.

We were asked to “ 37 a disability” for several hours one Sunday. Some members,38 , chose to use wheelchairs. Others wore sound-blocking earplugs (耳塞) or blindfolds (眼罩).Just sitting in the wheelchair was a 39 experience. I had never considered before how 40 it would be to use one. As soon as I sat down my 41 made the chair begin to roll. Its wheels were not 42 . Then I wondered where to put my 43 . It took me quite a while to get the metal footrest into 44 . I took my first uneasy look at what was to be my only means of 45 for several hours. For disabled people, “adopting a wheelchair” is not a temporary46 .I tried to find a 47 position and thought it might be restful, 48 kind of nice, to be 49 around for a while. Looking around, I 50 I would have to handle the thing myself! My hands started to ache as I 51 the heavy wheels. I came to know that controlling the 52 of the wheelchair is not going to be a (an) 53 task.My wheelchair experiment was soon 54 . It made a deep impression on me. A few hours of “disability” gave me only a taste of the 55 , both physical and mental, that disabled people must overcome.36. A. curious about B. interested in C. aware of D. careful with37.

A. weaknesses B. challenges C. anxieties D. illnesses2012Body language is the quiet, secret and most powerful language of all! It speaks 36 than words. According to specialists, our bodies send out more 37 than we realize. In fact, non-verbal communication (非言语交际) takes up about 50% of what we really 38 . And body language is particularly 39 when we attempt to communicate across cultures. Indeed, what is called body language is so 40 a part of us that it's actually often unnoticed. And misunderstandings occur as a result of it. 41 , different societies treat the 42 between people differently. Northern Europeans usually do not like having 43 contact even with friends, certainly not with 44 . People from Latin American countries 45 , touch each other quite a lot. Therefore, it's possible that in 46 , it may look like a Latino is 47 a Norwegian all over the room. The Latino, trying to express friendship, will keep moving 48 . The Norwegian, veryprobably seeing this as pushiness, will keep 49 --which the Latino will in return regard as 50 .Clearly, a great deal is going on when people 51 . And only a part of it is in the words themselves. And when parties are from 52 cultures, there's a strong possibility of 53 . But whatever the situation, the best 54 is to obey the Golden Rule: treat others as you would like to be 55 .36. A. straighter B. louder C. harder D. further37.

After 39 shouts of wildly wrong guesses the professor smiled a thin, dry smile, announced the 40 answer, and went on saying, “You have just 41 an important lesson about science. That is: Never 42 your own senses.”Twenty years later, the 43 could guess what the professor had in mind. He 44 himself, perhaps, as inviting his students to start an exciting 45 into an unknown world invisible (无形的) to the 46 , which can be discovered only through scientific 47 . But the seventeen-year-old girl could not accept or even 48 the invitation. She was just 49 tounderstand the world. And she 50 that her firsthand experience could be the 51 . The professor, however, said that it was 52 . He was taking away her only 53 for knowing and was providing her with no substitute (替代). “I remember feeling small and 54 .” The woman says, “and I did the only thing I could do.

I heard him saying to the nurse that he was in a hurry for an appointment at 9:30.The nurse had him take a 36 in the waiting area, 37 him it would be at least 40 minutes 38 someone would be able to see him. I saw him 39 his watch and decided, since I was 40 busy —my patient didn’t41 at the appointed hour, I would examine his wound.

历年高考全国卷1英语七选五真题汇编

2022Friendship needs care and attention to keep it in good health. Here are five ways to sustain(保持) long-distance friendships.·Set a regular dateLong-lasting friendships share the characteristic that both sides equally contact(联系) and share with one another. With busy schedules, squeezing in phone calls can be a challenge. 36 .·More isn’t always merrierMake sure you have communicated with your friend about how frequently each of you wants to be contacted and what method works best for you both. 37 . There are alternatives to constant written communication, such as leaving voice messages or having a group chat.·Practise empathy(共情)38 . The friend who is remaining needs to be sensitive to all the additional time demands placed on the friend who has moved. The one in the new environment should be sympathetic to the fact that your friend may feel abandoned.·39Anniversaries and birthdays carry even more weight in long-distance friendships. Although technology might make day-to-day communication possible, extra effort goes a long way on special days. Simply keeping a diary that keeps track of friends’ birthdays and other important dates will make sure nothing slips by you.·Don’t rely on technology alone40 , but long-distance friendships --even close ones-- may require more conscious effort to sustain. Try to seek out chances to renew friendships. How to do it? Just spend face-to-face time together whenever possible.A. Remember important datesB. Compensate by writing lettersC. It is also helpful for you to be a friendship keeperD. Try to find a time that works for both of you and stick to itE. Friends need to talk about their preferred methods of communicationF. It is easy to have a sense of connectedness through social mediaG. You may be the friend who left or the one who was left behind2021According to Jessica Hagy, author of How to Be Interesting, it’s not difficult to make yourself interesting at a dinner party.36 , if you’re out of your comfort zone or if you’re wandering into somebody’s house for the first time. So the main thing is just to show up and be adventurous, trying different foods and talking to strangers.People love to talk about themselves. If you can start the conversation with a question other than “What do you do for a living?”, you’ll be able to get a lot more interesting conversation out of whomever it is you’re talking to. 37 , it can bring in “I have this old, broken-down vehicle” or “I rode the bus with these crazy people who were laughing at silly jokes in the back.” It just opens up conversation.38 ? If you can’t take their wine away, you should certainly try to take away their soapbox (讲台). If you’re the host, you can ask them to help you in the kitchen with something and just remove them from the situation. 39 .And what about that other dinner-party killer: awkward silence? If you’re faced with an awkward silence at a dinner party, the only thing that always gets everyone talking again is to give the host a compliment(赞扬). 40 . Just quickly turn around and say, “This cake is extremely delicious and you have to tell me all about it.”So being interesting at a dinner party isn’t that hard.A. How do you know the hostB. The first step is to go exploringC. If you ask the question “How did you get here?”D. Be prepared to have awkward conversations with strangersE. Or turn the conversation into a topic where they have little to sayF. What about that person who had too much to drink or won’t stop talkingG. He or she is the person who is feeling the weight of that awkwardness the most2020A Few Tips for Self-AcceptanceWe all want it… to accept and love ourselves. But at times it seems too difficult and too far out of reach. __36__ Here’sa handful of ways that will set you in the right direction.●__37__ Do not follow the people who make you feel not-good-enough. Why do you follow them? Are you hoping that eventually you will feel empowered because your life is better than theirs? Know that your life is your own; you are the only you in this world.●Forgive yourself for mistakes that you have made. We are often ashamed of our shortcomings, our mistakes and our failures. __38__ You will make mistakes, time and time again. Rather than getting caught up in how you could have done better, why not offer yourself a compassionate (有同情心) response? “That didn’t go as planned. But, I tried my best.”●Recognize all of your strengths. Write them down in a journal. Begin to train your brain to look at strength before weakness. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today. __39__●Now that you’ve listed your strengths, list your imperfections. Turn the page in your journal. Put into words why you feel unworthy, why you don’t feel good enough. Now, read these words back to yourself. __40__ Turn to a page in your journal to your list of strengths and achievements. See how awesome you are?A. Feeling upset again?B. Where do you start?C. Nothing is too small to celebrate.D. Remember, you are only human.E. Set an intention for self-acceptance.F. Stop comparing yourself with others.G. When does the comparison game start?2019Is Fresh Air Really Good for You?We all grew up hearing people tell us to “go out and get some fresh air”. 36 According to recent studies, the answer is a big YES, if the air quality in your camping area is good.37 If the air you’re breathing is clean — which it would be if you’re away from the smog of cities — then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.Recently, people have begun studying the connection between the natural world and healing(治愈). 38 In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood(情绪). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 39 It gives us a great feeling of peace.40 While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D — but still protect your skin — put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D.A. Fresh air cleans our lungs.B. So what are you waiting for?C. Being in nature refreshes us.D. Another side benefit of getting fresh air is sunlight.E. But is fresh air really as good for you as your mother always said?F. Just as importantly, we tend to associate fresh air with health care.G. All across the country, recovery centers have begun building Healing Gardens.2018Color is fundamental in home design -- something you’ll always have in every room. A grasp of how to manage color in your spaces is one of the first steps to creating rooms you'll love to live in. Do you want a room that's full of life? Professional? Or are you just looking for a place to relax after a long day? 36 , color is the key to making a room feel the way you want it to feel.Over the years, there have been a number of different techniques to help designers approach this important point.37 , they can get a little complex. But good news is that there’re really only three kinds of decisions you need to make about color in your home: the small ones, the medium ones, and the large ones.38 . They’re the little spots of color like throw pillows, mirrors and baskets that most of us use to add visual interest to our rooms. Less tiring than painting your walls and less expensive than buying a colorful sofa, small color choices bring with them the significant benefit of being easily changeable.Medium color choices are generally furniture pieces such as sofas, dinner tables or bookshelves. 39 . They require a bigger commitment than smaller ones, and they have a more powerful effect on the feeling of a space.The large color decisions in your rooms concern the walls, ceilings, and floors. Whether you're looking at wallpaper or paint, the time, effort and relative expense put into it are significant. 40 .A. While all of them are usefulB. Whatever you're looking forC. If you're experimenting with a colorD. Small color choices are the ones we’re most familiar withE. It's not really a good idea to use too many small color piecesF. So it pays to be sure, because you want to get it right the first timeG. Color choices in this range are a step up from the small ones in two major ways2017If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me. 36The friends who introduced me to camping thought that it meant to be a pioneer. 37 We slept in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.I was, nevertheless, talked into going on another fun-filled holiday in the wilderness. 38 Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.39 We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.40 It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.A. This time there was no tent.B. Things are going to be improved.C. The trip they took me on was a rough one.D. I was to learn a lot about camping since then, however.E. I must say that I have certainly come to enjoy camping.F. After the trip, my family became quite interested in camping.G. There was no shade as the trees were no more than 3 feet tall.2016Secret codes(密码) keep messages private. Banks, companies, and government agencies use secret codes in doing business, especially when information is sent by computer.People have used secret codes for thousands of years. 36 Code breaking never lags(落后) far behind code making. The science of creating and reading coded messages is called cryptography.There are three main types of cryptography. 37 For example, the first letters of “My elephant eats too many eels” Spell out the hidden message “Meet me”.38 You might represent each letter with a number, for example. Let’s number the letters of the alphabet, in order, from 1 to 26. If we substitute a number for each letter, the message “Meet me” would read “13 5 5 20 13 5”.A code uses symbols to replace words, phrases, or sentences. To read the message of a real code, you must have a code book. 39 For example, “bridge” might stand for “meet” and “out” might stand for “me.” The message “Bridge out” would actually mean “Meet me”. 40 However, it is also hard to keep a code book secret for long. So codes must be changed frequently.A. It is very hard to break a code without the code book.B. In any language, some letters are used more than others.C. Only people who know the keyword can read the message.D. As long as there have been codes, people have tried to break them.E. You can hide a message by having the first letters of each word spell it out.F. With a code book, you might write down words that would stand for other words.G. Another way to hide a message is to use symbols to stand for specific letters of the alphabet.2015Building Trust in a Relationship AgainTrust is a learned behavior that we gain from past experiences. 36 That is a risk. But you can’t be successful when there’s a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.Unfortunately, we’ve all been victims of betrayal. Whether we’ve been stolen from, lied to, misled, or cheated on, there are different levels of losing trust. Sometimes people simply can’t trust anymore. 37 It’s understandable, but if you’re willing to build trust in a relationship again, we have some steps you can take to get you there.●38 Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.●39 If you’ve been betrayed, you are the victim of your circumstance. But there’s a difference between being a victim and living with a “victim mentality”. At some point in all of our lives, we’ll have our trust tested or violated.●You didn’t lose “everything”. Once trust is lost, what is left? Instead of looking at the situation from this hopeless angle, look at everything you still have and be thankful for all of the good in your life. 40 Instead, it’s a healthy way to work through the experience to allow room for positive growth and forgiveness.A. Learn to really trust yourself.B. It is putting confidence in someone.C. Stop regarding yourself as the victim.D. Remember that you can expect the best in return.E. They’ve been too badly hurt and they can’t bear to let it happen again.F. This knowledge carries over in their attitude toward their future relationships.G. Seeing the positive side of things doesn’t mean you’re ignoring what happened.2014The jobs of the future have not yet been invented. 36 By helping them develop classic skills that will serve themwell no matter what the future holds.1.

在人类文明史上,教育始终扮演着重要的角色。

从古希腊的雅典学院,到我国的孔子私学,再到今天的现代教育体系,教育一直是文化传承的重要载体。

教育通过培养人的道德品质、知识素养和创新能力,为文化的传承和发展提供了有力保障。

气候正义是环境主义在气候变化领域的具体发展和体现。

2000年前后,一些非政府组织承袭环境正义运动的精神。

开始对气候变化的影响进行伦理审视,气候正义便应运而生。

气候正义关注的核心主要是在气候容量有限的前提下,如何界定各方的权利和义务,主要表现为一种社会正义或法律正义。

从空间维度来看,气候正义涉及不同国家和地区之间公平享有气候容量的问题,也涉及一国内部不同区域之间公平享有气候容量的问题,因而存在气候变化的国际公平和国内公平问题,公平原则应以满足人的基本需求作为首要目标,每个人都有义务将自己的“碳足迹”控制在合理范围之内。

比如说,鉴于全球排放空间有限,而发达国家已实现工业化,在分配排放空间时,就应首先满足发展中国家在衣食住行和公共基础设施建设等方面的基本发展需求,同时遇到在满足基本需求之上的奢侈排放。

从时间维度上来看,气候正义涉及当代人与后代之间公平享有气候容量的问题,因而存在代际权利义务关系问题。

这一权利义务关系,从消极方面看,体现为当代人如何约束自己的行为来保护地球气候系统,以将同等质量的气候系统交给后代;从积极方面看,体现为当代人为自己及后代设定义务,就代际公平而言,地球上的自然资源在代际分配问题上应实现代际共享,避免“生态赤字”。

因为,地球这个行星上的自然资源包括气候资源,是人类所有成员,包括上一代、这一代和下一代,共同享有和掌管的。

我们这一代既是受益人,有权使用并受益于地球,又是受托人,为下一代掌管地球。

1.行驶中的汽车如果发生剧烈碰撞,车内的安全气囊会被弹出并瞬间充满气体。

若碰撞后汽车的速度在很短时间内减小为零,关于安全气囊在此过程中的作用,下列说法正确的是()A. 增加了司机单位面积的受力大小B. 减少了碰撞前后司机动量的变化量C. 将司机的动能全部转换成汽车的动能D. 延长了司机的受力时间并增大了司机的受力面积【答案】D【解析】【详解】A.因安全气囊充气后,受力面积增大,故减小了司机单位面积的受力大小,故A错误;B.有无安全气囊司机初动量和末动量均相同,所以动量的改变量也相同,故B错误;C.因有安全气囊的存在,司机和安全气囊接触后会有一部分动能转化为气体的内能,不能全部转化成汽车的动能,故C错误;D.因为安全气囊充气后面积增大,司机的受力面积也增大,在司机挤压气囊作用过程中由于气囊的缓冲故增加了作用时间,故D正确。

故选D。

2020年普通高等学校招生全国统一考试[新高考全国卷Ⅰ]试题及答案解析
历史地理学把空间和时间结合起来的特征,体现了发生学原理的应用,意味着对地理事物和地理现象的空间关系的研究,要从产生、形成、演变的过程来探寻其规律,这是近现代科学的重要特征。而地理环境的演变往往需要经历漫长的时间过程,如长江三峡、黄土高原、长江三角洲等地貌的形成和演变,时间之漫长达到十万至数千万年;我国许多城市的兴起距今已有1000年,而像武汉如从原始部落聚居算起,距今已达4000~5000年,从原始城址的出现算起距今也有3100~3600年。这种形成的演变过程,只有全面系统地进行观察和研究,才能探寻出规律性的内容。有了客观的规律,方能预测其未来的发展趋势。

对素食者和肠胃疾病患者来说,藜麦的发现是一个奇迹。

藜麦不含麸质,富含镁和铁,比其他种子含有更多的蛋白质,包括人体无法独自生成的必需的氨基酸。

美国宇航局宣布,藜麦是地球上营养最均衡的食物之一,是宇航员的理想之选。

产于安第斯山的藜麦有一个令西方消费者神往的传说:印加人非常重视藜麦,认为它是神圣的,并且称之为“万谷之母”。

不过,藜麦的爱好者却通过媒体发现了一个令人不安的事实。

从2006年到2013年,玻利维亚和秘鲁的藜麦价格上涨了两倍。

2011年,《独立报》称,玻利维亚的藜麦消费量“5年间下降了34%,当地家庭已经吃不起这种主食了,它已经变成了奢侈品”。

《纽约时报》援引研究报告称,藜麦种植区的儿童营养不良率正在上升。

2013年,《卫报》用煽动性标题提升了人们对这个问题的关注度:“素食者的肚子能装下藜麦令人反胃的事实吗?”该报称,贫穷的玻利维亚人和秘鲁人正在食用更加便宜的“进口垃圾食品”。

《独立报》2013年一篇报道的标题是“藜麦:对你有利--对玻利维亚人有害”。

这些消息传遍了全球,在健康饮食者之中引发了一场良心危机。

在社交媒体、素食博客和健康饮食论坛上,人们开始询问食用藜麦是否合适。

Ⅱ.(12分)一直流电压表,量程为1 V,内阻为1000Ω。

现将一阻值为5000~7000Ω之间的固定电阻R1与此电压表串联,以扩大电压表的量程。

为求得扩大后量程的准确值,再给定一直流电源(电动势E为6~7 V,内阻可忽略不计),一阻值R2=2000Ω的固定电阻,两个单刀开关S1、S2及若干导线。

(1)为达到上述目的,将答题卡上对应的图连成一个完整的实验电路图。

(2)连线完成以后,当S1与S2均闭合时,电压表的示数为0.90 V;当S1闭合,S2断开时,电压表的示数为0.70 V。

由此可以计算出改装后电压表的量程为V,电源电动势为V。

已知O、A、B、C为同一直线上的四点,AB间的距离为l1,BC间的距离为l2,一物体自O点由静止出发,沿此直线做匀速运动,依次经过A、B、C三点,已知物体通过AB段与BC段所用的时间相等。

24.(18分)图中滑块和小球的质量均为m,滑块可在水平放置的光滑固定导轨上自由滑动,小球与滑块上的悬点O由一不可伸长的轻绳相连,轻绳长为l。

开始时,轻绳处于水平拉直状态,小球和滑块均静止。

现将小球由静止释放,当小球到达最低点时,滑块刚好被一表面涂有粘住物质的固定挡板粘住,在极短的时间内速度减为零,小球继续向左摆动,当轻绳与竖直方向的夹角θ=60°时小球达到最高点。

求(1)从滑块与挡板接触到速度刚好变为零的过程中,挡板阻力对滑块的冲量;(2)小球从释放到第一次到达最低点的过程中,绳的拉力对小球做功的大小。

25.(22分)如图所示,在坐标系xOy中,过原点的直线OC与x轴正向的夹角φ=120°,在OC右侧有一匀强电场;在第二、三象限内有一匀强磁场,其上边界与电场边界重叠、右边界为y轴、左边界为图中平行于y轴的虚线,磁场的磁感应强度大小为B,方向垂直纸面向里。

粒子在磁场中的运动轨迹为纸面内的一段圆弧,且弧的半径为磁场左右边界间距的两倍。

粒子进入电场后,在电场力的作用下又由O点返回磁场区域,经过一段时间后再次离开磁场。

已知粒子从A点射入到第二次离开磁场所用的时间恰好等于粒子在磁场中做圆周运动的周期。

忽略重力的影响。

求(1)粒子经过A点时速度的方向和A点到x轴的距离;(2)匀强电场的大小和方向;(3)粒子从第二次离开磁场到再次进入电场时所用的时间。
