一般分为学习体会，工作体会，教学体会，读后感，观后感。

以下整理的关于四查四看学习心得体会5篇，欢迎阅读参考!关于四查四看学习心得体会1针对新疆严峻的空防形式以及保卫系统有出现纪律作风懒散的现象，南航新疆分公司客舱部开展以四查四强化为主题的专项执勤作风教育整顿活动，近日，南航新疆分公司客舱部成立了整顿小组，通过四查四强化来切实扭转安全员在执勤纪律等其他方面存在懒散的问题。

通过学习四查四强化内容，我发现，虽然在工作中取得了一定的成绩，但也存在一些不足，主要是表现在对有些专业知识掌握的还不够，和有经验的同事比较还有一定差距，这和客舱部正在在努力打造一支政治合格，纪律严明，作风过硬，业务精湛的安全保卫队伍不相匹配，所以在今后工作中，我一定认真总结经验，克服不足，努力把工作做得更好，同时要做到发扬吃苦耐劳精神。

面对部门任务多、任务重的工作性质，不怕吃苦，主动找事干，做到眼勤、嘴勤、手勤、腿勤，积极适应各种艰苦环境，在繁重的工作中磨练意志，增长才干。

在学习好的方面的同时还要解决自身的不足，例如：专业理论基础还不够扎实，动手实际操作能力还较差，实际和理论知识还没有完全融合。

加强学习，勇于实践，博览群书，在向书本学习的同时注意收集各类信息，广泛吸取各种营养;同时，讲究，端正学习态度，提高学习效率，努力培养自己具有扎实的理论功底、辩证的思维方法、正确的思想观点、踏实的工作作风。

要始终坚持多看、多听、多想、多问、多做的方针，不断提高自身的工作能力和工作效率，力求把工作做得更好，树立优秀员工的良好形象。

今后，在工作中要提高主动性与积极性。

不再只是被动地等待别人告诉我应该做什么，而是应该主动去了解自己要做什么，并且规划它们，然后全力以赴地去完成。

对待自己的学习和工作，要全力投入，不断努力。

这就是优秀员工应该有的工作作风，态度决定一切，态度至关重要。

2013春《大学英语4》综合复习资料I. Reading ComprehensionPassage 1For ages, sailors have said that it is good luck to see dolphins swimming alongside boats. Their presence meant that land was near, which would be vital information if a boat and her crew were in danger. Some dolphins have even protected shipwrecked sailors from sharks. It is no wonder that these unique and fascinating creatures have long been known as our friends.You may think dolphins are fish, but they are actually mammals. They are related to whales and porpoises, and they evolved around 10 million years ago. Dolphins breathe air, give birth to live young, and feed them milk. They are social animals, living together in groups ranging in size of up to 12.In places rich in food, many schools can combine together to form schools of up to 1,000 dolphins.Dolphins are thought to be intelligent animals because of their playfulness, curiosity, and quick ability to learn. They seem to communicate with each other through a combination of squeaks, whistles, and clicks. While scientists don't know what they are going on about, it is thought that dolphins are telling each other that food is nearby, or warning each other of approaching danger. Dolphins use sonar to discover an object's size, shape, and location. By sending out a series of clicks and receiving the echo that bounces off the object, they can differentiate between a shark and a boat.Unfortunately, dolphins have faced increasing danger in recent years. Fishermen in pursuit of profitable tuna may accidentally trap dolphins in their nets, killing them in the process. These intelligent mammals of the sea deserve our protection and respect.1. Dolphins have been human's friends because of _______D_____.A. sailors may know that the land is not far awayB. some dolphins protect sailors from shark attacksC. sailors can communicate with themD. both A and B2. Which of the following statement about dolphin is not true? AA. Dolphins lay eggs under the sea.B. Dolphins can communicate with each other by sending out sounds.C. Dolphins have abilities to learn.D. Dolphins prefer to live in groups up to hundreds.3. How do dolphins communicate with one another? DA. Through radio waves.B. By sending out gases.C. By clapping their fins together.D. Through various noises.4. According to the article, what makes a threat to dolphins? DA. Whales.B. Tuna.C. Sailors.D. Fishermen.5. What is the main idea of the last paragraph? BA. Fishermen accidentally trap dolphins.B. We should take some actions to stop killing dolphins.C. Dolphins often live with tunas.D. More and more dolphins are in danger in the recent years.Passage 2The city has always been an engine of intellectual life, from the 18th-century cafes of London, where citizens gathered to discuss chemistry and politics, to the Left Bank bars of modern Paris, where Picasso talked about modem art. Without the metropolis, we might not have had the great art of Shakespeare.And yet, city life isn’t easy. Now scientists have begun to examine how the city affects the brain, and the results are depressing. Just being in an urban environment, they have found, impairs (损害) our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory, and suffers from reduced self-control. While it’s long been recognized that city life is exhausting, this new research suggests that cities actually dull our thinking, sometimes dramatically so.One of the main forces at work is a complete lack of nature, which is surprisingly beneficial for the brain. Studies have demonstrated, for instance, that hospital patients recover more quickly when they can see trees from their windows, and that women living in public housing are better able to focuswhen their apartments overlook a lawn. Even these glimpses of nature improve brain performance, it seems, because they provide a mental break from the urban life.This research arrives just as humans cross an important milestone (里程碑). For the first time in history, the majority of people live in cities. Instead of inhabiting wide-open spaces, we’re crowded into concrete jungles, surrounded by traffic and millions of s trangers. In recent years, it’s become clear that such unnatural surroundings have important implications for our mental and physical health, and can powerfully alter how we think.6. Which of the following is the main idea of this passage? BA. The city inspires talented people.B. The city hurts your brain.C. The city has many pleasures and benefits.D. The city seriously affects the natural balance.7. The word “metropolis” in the first paragraph is closest in meaning to___C____.A. citizenB. natureC. cityD. stress8. People have just come to realize that____D___.A. human attention is a scarce resourceB. city life can make people very tiredC. the city is an engine of intellectual lifeD. an urban environment is damaging to the brain9. What is the factor mentioned in the third paragraph that helps the hospital patients recover more quickly? AA. Nature.B. Better treatment.C. Experienced doctors.D. Good medicine.10. According to the passage, which of the following statements is TRUE? CA. Different aspects (方面) of an urban environment, such as the crowded streets, can lead to an increase in self-control.B. Small changes in urban design cannot reduce the negative side effects of city life.C. For the first time in history, the earth’s population is more urban than rural.D. A walk down a busy city street will improve brain performance.Passage 3Your success in your studies will also depend upon your motivation（动机）. This need or desire to achieve a certain goal can make the difference between success and failure. Motivation can come from two sources: from inside of you or from outside of you. In the first case, motivation comes from your hopes and expectations, from your desire to do something or to be someone. Study purposes that result from personal inner desires are individual, and various. If you have not already done so, you should think carefully about what you hope to gain from your studies, and why. You should set a goal and direct all your study efforts toward reaching it. A goal of this kind is important because it will determine the direction and degree of your motivation for study.Not everyone is highly motivated from within and no one is continuously motivated from within. Fortunately there is another source of motivation：from outside. In education the most obvious kind of outside motivation is grades. For many students, course grades are an immediate, short-range motivation for study. This is one of the reasons for examinations and grades, but they must not become a goal in themselves. Grades help to motivate you from day to day, but they are only small, artificial steps to your ultimate goal. It would be wrong to set grades as your only ambition.A textbook like this cannot provide you with motivation；that must come from yourself. But as an encouragement, it is useful to know that good study habits depend upon good motivation. And good study habits are important because they help you get more done in less time. It is not a matter of how much you study；more important is how well you study.11. Inside motivation comes from______D______.A. your need and desireB. your hopes and expectationsC. your desire to do something or to be someoneD. both B and C12. Study purposes_____A_______.A. are different from person to personB. are personal inner desiresC. share some common pointsD. should be carefully made13. If you haven't set a goal in your studies,______C______.A. you will most probably become a failureB. you will never be a good studentC. you may lose direction and lack motivationD. you won't have good study habits14. According to the passage, why are examinations and grades necessary in education? BA. Because they can make the difference between success and failure.B. Because they can motivate many students to study harder.C. Because they can check what you have gained from your studies.D. Because they are small, artificial steps to an ultimate goal.15. If you want to be an efficient learner, you must_____D_______.A. have clear study purposesB. be always motivated from both inside and outsideC. set grades as your ambitionD. have good study habitsPassage 4Ask three people to look out the same window at a busy street corner and tell you what they see. Chances are that you will receive three different answers. Each person sees the same scene, but each perceives something different about it.Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may say that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses — in this case our eyes — tell us.Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene.16. What does the passage mainly tell us? BA. Perceiving has nothing to do with seeing.B. Perceiving differs from seeing.C. Seeing is closely connected to perceiving.D. Seeing has much to do with perceiving.17. The phrase "with four children in tow" in the second paragraph is closest in meaning to "_____A______".A. with four children following closely behind herB. with four children tied to each other with a ropeC. with four children dragging a rope held by herD. with four children dragged in a small cart18. According to the passage, perceiving is an action _____C______.A. that tells us information through our eyesB. that gives us senses in the mindC. that explains what our senses tell usD. that makes our mind different19. The psychologists are trying to draw their conclusion____D_______.A. by asking different people to tell how they perceive the same sceneB. by using a scientific approach in setting up their experimentsC. by determining how a person experiences the world around himD. by measuring and charting the results of many experiments20. Which of the following statements is NOT true? CA. Different people may perceive the same scene in a different way.B. That a policeman gives a motorist a ticket means the motorist is fined.C. No people share the same perception when they are asked to see the same scene.D. The psychologists can control all of the factors in their experiments.Passage 5To understand how Americans think about things, it is necessary to understand "the point". Americans mention it often："Let's get right to the point", "My point is ...","What's the point of all this?"The "point" is the idea or piece of information that Americans suppose is, or should be, at the center of people's thinking, writing, and spoken comments. Speakers and writers are supposed to "make their points clear", meaning that they are supposed to write clearly the idea or piece of information they wish toexpress.People from many other cultures have different ideas about "the point". Africans traditionally tell stories that express the thoughts they have in mind, rather than stating "the point" clearly. Japanese traditionally speak indirectly, leaving the listener to figure out what the point is. Thus, while an American might say to a friend, "I don't think that coat goes very well with the rest of your outfit", a Japanese might say, "Maybe this other coat would look even better than the one you have on." Americans value a person who "gets right to the point". Japanese are likely to consider such a person insensitive if not rude.The Chinese and Japanese languages are characterized by vagueness and ambiguity（模糊）. The precision（精确）and directness Americans associate with "the point" cannot be achieved, at least not with any grace, in Chinese and Japanese. Speakers of those languages thus have to learn a new way of reasoning and expressing their ideas if they are going to communicate satisfactorily with Americans.21. By “the point”,Americans mean_____B_______.A. the idea or information in their mindB. the most important idea or informationC. what they think, write and speakD. what they wish to express22. Compared with people from many other cultures, Americans are_____A_______.A. direct and honestB. clear and talkativeC. impolite and rudeD. traditional and silent23. A typical American seems to be ___D___to a typical Japanese.A. sensitive and rudeB. insensitive but not rudeC. sensitive instead of rudeD. insensitive and even rude24. Which of the following statements is NOT true according to the passage? DA. You are expected to state your idea clearly when speaking to an American.B. Telling stories to express their ideas is a traditional way of Africans.C. Japanese often imply their disapproval with polite words.D. Chinese and Japanese languages are hard to understand because they are not clear.25. A conclusion can be made that_____C_______.A. Americans and Africans cannot communicate satisfactorilyB. Africans and Japanese cannot communicate satisfactorilyC. Misunderstanding may arise when Americans communicate with ChineseD. Chinese and Japanese will certainly get on well with each otherPassage 6The only certainties I’ve found in life are death and change. One is an end, the other a be ginning. Change is life. Without change there would be no growth, no understanding, no relating and no surprises. We are by nature changing beings. Still, we seem to fear and resist it more than any other aspect of life.Healthy human beings welcome the opportunity to adapt to new experiences. In fact they are quite comfortable in a constant state of change. They know about the possibility of becoming someone new each moment. Only habit and indifference prevent the rest of us from having the same outlook.When we don’t care, or submit ourselves to patterns and routines, we begin to stagnate. We are inclined to accept the comfort able illusion that life is a series of habits and conditioned responses. In reality this is a comfort more like a disease, which leads to a kind of intellectual and emotional death. We can allow ourselves and dynamic world to go to waste. Ellen Glasgow, an American novelist, said, “The only differences between a rut（车辙）and a grave are their dimensions.”To accept new ideas and give up old values and habits is not always comfortable. It is often easier for us to deny that there may be more appropriate, more creative possibilities for our lives. We fail to understand that when we resist potentialities, life becomes at best a continual struggle; at worst, it passes us by and we are left alone and lonely.26. Which of the following best expresses the main idea of the first paragraph? CA. Change is as inevitable as death.B. Some of us fear change because it leads to death.C. Change is characteristic of the life of human beings.D. Death is the inevitable result of change.27. Which of the following is NOT true? AA. All human beings want to be healthy by adapting to new experiences.B. Some people do not welcome change as a result of habit and indifference.C. Constant change results in comfort for some people.D. Healthy human beings are not subjected to habit and indifference, and keep on trying to become someone new.28. According to the passage, “The only differences between a rut and a grave are their dimensions” suggests that __A____.A. if we regard life as a series of habits and conditioned responses, our life actually endsB. some people die a kind of intellectual and emotional deathC. death is inevitableD. too much comfort often results in death29. The word “stagnate” in paragraph 3 means ___B___.A. stop working hardB. stop developingC. become weakD. fall ill30. The author’s main purpose in writing the last paragraph is ___C___.A. to tell us that if we resist change, we’ll suffer from loneliness in lifeB. to show the reason why some people do not accept new ideas or give up old values and habitsC. to come to the conclusion that if we go against the law of change, it will be impossible for us to enjoy lifeD. to show that it is because of our desire to seek comfort that we tend to deny our livesPassage 7Many of us believe that a person’s mind becomes less active as he grows older. But this is not true, according to Dr. Lissy F. Jarvik, professor of psychiatry (精神病学) at the university of California, Los Angeles, and a board member of the New Center for Aging at the Veterans Hospital. She has studied the mental functioning of aging persons for several years. For example, one of her studies concern 136 pairs of identical twins, who were first examined when they were already 60 years old. As Dr. Jarvik continued the study of the twins into their 70s and 80s, their minds did not generally decline as was expected.However, there was some decline in their psycho-motor speed. This means that it took them longer to complete mental tasks than it used to. But when speed was not a factor, they lost very little intellectual ability over the years. In general, Dr. Jarvik’s studies have shown that there is no dec line in knowledge or reasoning ability. This is true not only into the 30s and 40s, but into the 60s and 70s as well.As for learning new things, and ability to remember, studies by Dr. Jarvik and others show that the old are equal to the young. It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call “loss of memory” is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing, or poor vision, or inattention, or was trying to learn the new thing at too fast a pace.In the cases where the older person’s mind really seems to decay (衰退), it is not necessarily a sign of a decay due to old age. Often it is simply a sign of a depressed emotional state. This depression usually can be counteracted by counseling, a medical treatment with a psychologist, which fights depression. In American society, when an older person loses something, we tend to call him or her “senile”. But notice that when a younge r person loses something, he does not blame it on senility or loss of memory. He finds some other excuse!31. According to Dr. Jarvik’s studies, middle-aged and older persons should expect to ___D___.A. remember lessB. reason betterC. learn fewer new thingsD. lose little ability to remember, reason or learn32. A long term study of 136 pairs of twins showed that the only factor that declined over the years was _____B_____.A. the reasoning abilityB. the psycho-motor speedC. the decline in knowledgeD. the loss of intellectual ability33. Both younger and older persons should realize that _____D_______.A. a sign of a decay due to old age is a natural lawB. mental decay due to aging is closely related to one’s health conditionsC. a good emotional state can ensure a longer lifeD. mental decay due to aging is much less common than most of us believe34. What is the probable meaning of “counteract” from the context? BA. convincedB. lessenedC. addedD. rewarded35. Which of the following statements can be inferred from the passage? AA. People, either young or old, tend to view their mental decay incorrectly.B. With ageing, one’s emotional state is on the decline.C. Old people are not well educated and are thus slow to pick up new things.D. The decline of intellectual ability is usually accompanied by the drop in psycho-motor speed.Passage 8The only certainties I’ve found in life are death and change. One is an end, the other a beginning. Change is life. Without c hange there would be no growth, no understanding, no relating and no surprises. We are by nature changing beings. Still, we seem to fear and resist it more than any other aspect of life.Healthy human beings welcome the opportunity to adapt to new experiences. In fact they are quite comfortable in a constant state of change. They know about the possibility of becoming someone new each moment. Only habit and indifference prevent the rest of us from having the same outlook.When we don’t care, or submit ourselves to patterns and routines, we begin to stagnate.

According to Marshall McLuhan, a famous Canadian educator, “Our age of anxiety is, in great part, the result of trying to do today’s job with yesterday’s tools ― with yesterday’s concepts.”Santa Barbara in California was faced with the same danger some years ago and the city officials called a meeting of the city engineers and water department to find new tools ― new concepts to save la wns.The solution was gray water. The term gray water is given to the water we use when we wash our hands at the sink, take showers, wash clothes, etc. That water is going into the sewer (下水道) or septic tanks (化粪池) at an alarming rate.The water can save lawns and trees without any harm. Santa Barbara developed an attachment that could be installed on the plumbing (管道设备) of the city homes for as little as $50 that would permit this valuable water to save lawns and landscaping from drying up without risk to the citizens. The city water department in Santa Barbara arranged to install the units and bill homeowners the small cost added to their low monthly payments until it was paid out.The only gray water that is a threat is the water used in the washing ma chine and even that is safe to use on the lawn if you’re careful about what kind of soap you use.41.

关于“4PT”防谐振措施的说明1 概述在35kV及以下电网中性点不接地系统中，作绝缘监视的电磁式电压互感器由于铁磁谐振导致破坏是一种普遍现象。

长期以来，电力系统为防止这种破坏研究并采取了很多措施，并在电力行业标准中（例如：DL/T620-1997《交流电气装置的过电压保护和绝缘配合》) 作了一些推荐性的规定。

上世纪80年代末期以来，大连电业局采用了在电压互感器高压侧中点经一个互感器接地的接线方式，消谐效果较为满意，后来很多地方也相继采用，此称“4PT”防谐措施。

该措施目前已经成为一种较为通行的方法，但也在不断完善。

以下就消谐原理和效果作简要说明。

2 “4PT”接线图“4PT”接线（基本的原理电路）如图1。

图1中A′N′,B′N′,C′N′是三个单相电压互感器，应是全绝缘但按相压设计的接地电压互感器，本身有一个二次绕组（未画出）和一个剩余电压绕组，N接地为一个独立的单相电压互感器，该互感器可以是全绝缘结构，也可以是半绝缘结构，一般有两个线圈，一个是二次绕组，一个是剩余电压绕组，剩余电压绕组有的是和普通的，即和接成星形的主PT一样，但原理上其额定电压应为100V。

3 消谐机理“4PT”接线的防谐机理，简单的从稳态分析，即当单相接地时，互感器中点对地有相电压产生，而主PT仍处于正序对称电压之下，互感器电感并不发生改变，在零序回路中仅有单相电压互感器一种磁化电感，从根本上破坏了铁磁谐振的条件。

3.1 稳态分析如图1，当系统在C相“D”点发生对地短路（死接地），主电压互感器电压不变，中点对地产生相电压，简单推导如下：在NCD╧N回路里，因∑U=0，可得U N╧=-U C（U C——为电源相电压，即U CN）在NBB′Ｎ′╧N回路里，因∑U=0，得U N╧=U N╧ =-U C这就是说，单相接地，互感器中点对地有相电压产生。

在DC′N′╧D回路里，因∑U=0，可得U C′N′ =-U N′╧=U C……⑴即接地相电压互感器仍为相电压，与U AN′和U BN′仍组成三相对称电压系统。

小班数学教案及教学反思《4的形成》教学目标1.让孩子们掌握数字4的基本含义和表示方法。

2.对孩子进行数形结合的教育，探索数字4的不同组合方式并学会它们的应用。

3.鼓励孩子们表达自己的思考和想法，并加强思维能力的训练。

教学内容1.探索数字4的不同组合方式。

例如，4个同样大小的方格可以拼成一个较大的正方形，或者可以排成一排，由此引导孩子们理解和掌握数字4的不同表示方法。

2.学习数字4的常见表现形式，例如用手指表示数字4，或者用棋子、积木等实物表示数字4。

3.通过简单的游戏和活动来加深孩子对数字4的理解和记忆。

例如使用卡片游戏，让孩子们组成数字4的各种组合形式。

教学流程第一步：探究数字4的含义和表示方法1.引入数字4，让孩子们对数字4有一个初步的了解。

2.展示数字4的几种表示方法，例如手指、棋子等，并关注个别学生的理解情况。

3.引导孩子一起探讨数字4的不同组合方式，例如正方形、长方形等。

第二步：理解数字4的常见表示方式1.引入手指、棋子等实物，让孩子们实践和运用数字4的常见表现形式。

2.让孩子们动手操作，探索数字4的组成方式。

第三步：游戏和活动1.使用卡片游戏，让孩子们组成数字4的各种组合形式。

2.进行班级竞赛，看谁能用最少的积木拼出数字4。

教学反思本次数学教学活动中，我们通过不同的探究、实践和游戏方式，让孩子们更好地理解和掌握数字4的基本含义和表示方法。

从整体上来看，孩子们表现出了良好的学习态度，积极参与课堂活动。

但是也存在一些不足之处，例如教学方式可能略显单一，没有很好地贯彻数形结合的思想，增强了孩子们数学意识的培养。

同时，教学内容也可能存在着一定的局限性，没有很好地满足孩子们的学习需求。

因此，在今后的教学实践中，我们应该更加注重教学方法的多样性和创新性，让孩子们在体验中学习，提高他们的学习兴趣和学习主动性。

同时，也应该更加关注学生的个体差异，激发每个学生的潜力，在不断完善自己的同时，不断提升教学质量。

关于成长四季作文集锦5篇成长的四季，五颜六色，又多姿多彩。

下面给大家分享一些关于成长四季作文，希望对大家有帮助。

关于成长四季作文1有多少个春夏秋冬，就有多少悲欢离合;有多少次四季更替，就有多少五彩魂梦。

成长路上，我陶醉春的轻风，聆听夏的小雨，憧憬秋的冷月，亲吻冬的冰雪，是快乐?是烦恼?个中滋味我自在四季中品尝。

春风轻扬儿时的我喜欢在阳光明媚的春日里放风筝。

时而拉着它往东奔跑，时而拽着它往西徜徉，看着它披着太阳的金光，在空中快乐的飞翔，与风为朋，和云作伴，我以为它应该是很开心的，于是我也很开心，我心也飞翔。

长大后，我也成了一只“风筝”，这时我才知道风筝的苦恼：不管飞多高，飞多远，命运都不在自己手中，被人约束，不由自主。

我喜欢学习，因为不断的学习可以让我不断地了解这个充满神奇的世界。

可“分、分、分”不知何时竟成了我的命根，我无时不被它牵制，不被它束缚，分高则喜，分低则忧，在分数面前我“战战兢兢，如履薄冰”。

夏雨淅沥听，“淅沥沥、淅沥沥”夏雨亲吻大地的声音。

它溅起的水珠是时间在空气中狂饮，吹起的一个个泡泡。

我喜欢这在云中酝酿了不知多少年的水分子，带着夏日的余温终于落到地面，适时地滋润大地，也洗涤了忧郁的人儿心中的阴霾。

多少个雨天我们倚窗听雨，门前戏水……可现在，我的朋友，他站在雨的那头，我站在雨的这头，被这孩提时觉得可爱非常而现在面目可憎的雨帘隔住，雷电还不时夹在雨中展露狰狞的笑容……不知是生活让他变得邪恶为伍，还是成长让我变得太明白是非曲直，亦或者是这雨把我们的心膈膜了。

我怀念那孩提的小雨，怀念心纯如雨的他。

秋月朦胧“你见过世上最美丽的花儿吗?”“我见过，它就绽放在你微笑的脸上。

”她笑得真美，真像一朵娇艳欲滴的花。

秋月朦胧中，我多想伸手去将它摘下，明明看起来是触手可及的距离，可当我快触到的时候花就离我远一点。

后来我才明白，我的双手还太年轻，不懂得如何呵护这花，也没到“护花”的时候，何不把这年少的懵懂，青春的萌动温存在心中，只要时机成熟，美丽的鲜花自然会在心底生根发芽，茁壮长大。

关于建立4个以学长效机制的意见

1. 学长选拔机制：建立一套严格的学长选拔机制，通过学业成绩、综合素质和领导能力等方面的评估，选拔出合适的学长担任学长职务。

选拔过程要公正、透明，确保学长的水平和能力能够真正帮助到学弟学妹。

2. 学长职责明确化：明确学长的职责和义务，使其在帮助学弟学妹方面有明确的目标和任务。

学长应该负责帮助学弟学妹解决学习和生活中的问题，提供学习经验和指导，并积极参与学院组织的各类活动，为学弟学妹提供帮助和指导。

3. 学长培训机制：建立学长培训体系，培训学长在帮助学弟学妹方面的能力和技巧。

培训内容可以包括沟通技巧、心理辅导、学业指导等方面的知识和技能，使学长能够更好地履行自己的职责。

4. 学长评价机制：建立学生对学长的评价机制，让学弟学妹对学长的表现进行评价和反馈。

通过学弟学妹的评价，可以及时发现学长的不足之处，并采取相应的改进措施，提高学长的服务质量。

以上是建立4个以学长效机制的一些建议，通过建立这种机制，可以促进学生之间的师兄师弟关系，提高学生的学习和发展水平。
