学习报告英语范文Learning ReportAs a student, I believe that learning is a lifelong journey and it's important to reflect on our learning experiences. In this report, I will share my thoughts on the learning process, the challenges I faced, and the strategies I used to overcome them.Firstly, I believe that effective learning requires a positive attitude and a growth mindset. It's important to stay curious, open-minded, and willing to embrace new challenges. I always try to approach my studies with a sense of curiosity and a desire to learn, which has helped me stay motivated and engaged in my learning process.One of the challenges I faced during my studies was time management. Balancing my academic workload with other commitments was often stressful and overwhelming. To overcome this challenge, I started using a planner to schedule my study sessions, assignments, and other activities. I also learned to prioritize tasks and setrealistic goals for myself, which helped me manage my time more effectively.Another challenge I encountered was understanding complex concepts in certain subjects. I found that breaking down the material into smaller, more manageable parts and seeking help from teachers and peers were effective strategies for overcoming this challenge. Additionally, I made use of online resources and educational videos to supplement my learning and gain a deeper understanding of the material.In terms of language learning, I faced difficulties in improving my speaking and listening skills. To address this, I engaged in conversations with native speakers, watched English movies and TV shows, and listened to podcasts and music in English. These activities not only improved my language skills but also exposed me to different accentsand colloquial expressions.Overall, I believe that self-reflection and awillingness to adapt and improve are essential componentsof the learning process. By acknowledging my weaknesses andseeking opportunities for growth, I have been able to overcome challenges and make progress in my studies.中文部分：作为一名学生，我相信学习是一生的旅程，重要的是要反思我们的学习经验。

However, reading is not just a form of entertainment; it is a window to the world, a tool for personal growth, and a means of intellectual development. As an avid reader myself, I have experienced firsthand the joys and benefits that reading brings. This report aims to explore the many reasons why reading is worth our time, with a specific focus on English literature.I. The Power of Imagination:Reading allows us to embark on a journey of imagination. Through the carefully crafted words of authors, we are transported to different worlds, eras, and perspectives. From Charles Dickens' London to J.R.R. Tolkien's Middle-earth, the power of imagination knows no bounds. As readers, we get to immerse ourselves in these landscapes, feel the emotions of the characters, and broaden our horizons.II. Language Acquisition and Improved Communication:Engaging with English literature has proven to be an effective way to enhance language acquisition. Whether you are a native English speaker or a language learner, reading exposes you to various writing styles, vocabulary, and grammatical structures. Over time, this exposure helps improve your own communication skills by boosting your vocabulary, sentence structure, and even critical thinking abilities.III. Emotional Empathy and Increased Cultural Understanding:Books have the remarkable ability to evoke emotions within us and enable us to connect with characters on a deep level. This emotional empathy not only improves our understanding of others but also contributes to our own personal growth. By reading diverse stories set in different cultures, we gain valuable insights into the lives and experiences of people from various backgrounds. This broadens our perspective, enhances our empathy, and promotes cultural understanding.IV. Intellectual Stimulation and Cognitive Development:Reading stimulates our minds and challenges our thinking. It exposes us to complex ideas, diverse perspectives, and different ways of problem-solving. From philosophical discussions in Fyodor Dostoevsky's works to scientific theories in Richard Dawkins' books, diverse literary genres offer an avenue for intellectual growth.Furthermore, research has shown that regular reading can enhance memory, concentration, and overall cognitive function.V. Stress Reduction and Emotional Well-being:When we immerse ourselves in a good book, we often experience a sense of escape from everyday worries and stresses. Reading provides a soothing retreat, allowing us to relax, unwind, and recharge our mental batteries. It is a form of entertainment that promotes emotional well-being, alleviating anxiety, depression, and other mental health conditions.Conclusion:Reading is a multifaceted activity that brings immense joy and numerous benefits. It enhances our language skills, broadens our horizons, and enriches our lives in countless ways. English literature, with its diverse range of genres and authors, offers a world of opportunities for intellectual growth and personal development.

He suffered enormous pain, such as hunger, thirst, beating and abuse. While reading the tragic experiences of the little Oliver, I was shocked by his sufferings. I felt for the poor boy, but at the same time I detested the evil Fagin and the brutal Bill. To my relief, as was written in all the best stories, the goodness eventually conquered devil and Oliver lived a happy life in the end. One of the plots that attracted me most is that after the theft, little Oliver was allowed to recover in the kind care of Mrs. Maylie and Rose and began a new life. He went for walks with them, or Rose read to him, and he worked hard at his lessons. He felt as if he had left behind forever the world of crime and hardship and poverty.How can such a little boy who had already suffered oppressive affliction remain pure in body and mind? The reason is the nature of goodness. I think it is the most important information implied in the novel by Dickens-he believed that goodness could conquer every difficulty. Although I don’t think goodness is omnipotent, yet I do believe that those who are kind-hearted live more happily than those who are evil-minded.For me, the nature of goodness is one of the most necessary character for a person. Goodness is to humans what water is to fish. He who is without goodness is an utterly worthless person. On the contrary, as the famous saying goes, ‘The fragrance always stays in the hand that gives the rose’, he who is with goodness undoubtedly is ahappy and useful person. People receiving his help are grateful to him and he also gets gratified from what he has done, and thus he can do good to both the people he has helped and himself.To my disappointment, nowadays some people seem to doubt the existence of the goodness in humanity. They look down on people’s honesty and kindness, thinking it foolish of people to be warm-hearted. As a result, they show no sympathy to those who are in trouble and seldom offer to help others. On the other hand, they attach importance to money and benefit. In their opinion, money is the only real object while emotions and morality are nihility. If they cannot get profit from showing their ‘kindness’, they draw back whe n others are faced with trouble and even hit a man when he is down. They are one of the sorts that Ireally detest.Francis Bacon said in his essay, ‘Goodness, of all virtues and dignities of the mind, is the greatest, being the character of the Deity, and without it, man is a busy,mischievous, wretched thing, no better than a kind of vermin.’That is to say a person without goodness is destined to lose everything. Therefore, I, a kind person, want to ___ those ‘vermin-to-be’ to learn from the kind Oliver and regain thenature of goodness.2.双城记After reading "A tale of two cities""A tale of two cities" is one of Dickens's most important representative works.The novel profoundly exposed the society contradiction before the FrenchRevolution,intensely attacks the aristocratic social class is dissolute and cruel,and sincerely sympathizes with the depressed classes.The novel also described many magnificent scenes like the revolt people attacked Bastille and soon,which displayed people's great strength.The novel has portrayed many different people. Doctor Mate is honest and kind but suffers the persecutionactually ， Lucie is beautiful and gentle ，Charles is graceful and noble，Lorry is upright and honest ，Sydney is semblance of indifferent, innermost feelings ofwarm,unconventional but also selfless and lofty，Miss Pross is straightforward and loyal，Evremonde brothers are cruel and sinister......The plex hatred is hard to solve, the cruel revenge has made more hatreds, loves rebirth in the hell edge,but take the life as the price.As an outstanding writer,in Dickens's work,the language skill is essential.Each kind of rhetoric technique,like the analogy,the exaggeration,the contrast,the humorous,and the taunt are handled skillfully,and the artistry of the workis also delivered the peak."A tale of two cities" has its difference with the general historical novel, its character and the main plot are all fictionalizes.With the broad real background of the French Revolution,the author take the fictional character Doctor Mate's experience as the main clue,interweaves the unjustcharge, love and revenge three independences but also incident cross-correlation storiestogether,the plot is criss-crossed,and the clue is plex.The author use insert narrates,foreshadowing,upholstery and so many techniques,causes the structure integrity and strictness,the plot winding anxious and rich of theatrical nature,it displayed the remarkable artistic skill.the style "A tale of two cities" is solemnity and melancholy,fills indignantion,but lacks the humor of the early works.3.老人与海This year summer vacation, I read the American well-known writer Hemingway's novel " old person and sea ". I extremely admire in the novel the senior fisherman's will, he let me understand one person certainly must have relentless spirit, only then could obtain suessfully.The novel description is one year near sixty years of age senior fisherman, when alone goes to sea in one fishing, fished one big fish, actually did not pull. The senior fisherman socialized several days after the fish, only then discovered this was the big marlin which one surpassed the oneself fishing boat several fold, althoughknew perfectly well very difficult to win, but still did not give up. Afterwards and further because in the big marlin wound fish fishy smell brought in several crowds of shark fish snatches the food, but the old person still did not hope like this to give up, finally highlightedencircles tightly, returned to the big fish belt thefishing port, lets other fishermen not admire already.When I read " the senior fisherman think: Here to the seacoast really was too near, perhaps could have a bigger fish ina farther place... " When, I extremely admire this senior fisherman, because he by now already projected on some fish, but he had not settled to the present situation, but was approaches the bigger goal advance. Again has a look us, usually meets one slightly is difficult, we all plain incessantly. We will be the motherland future, will be supposed to like this old person same mind lofty aspiration, will even better pursue even better, the bigger goal.When I read " the big marlin start fast to gather round the young fishing boat hover, twined the cable on the mast, the old person right hand lifted up high the steel fork, leapt the water surface in it the flash, did utmost throws to its heart, one wail ended the big fish's life, it was static static floats on the water surface... " When, my heart also liked together the big stone falls. I extremely admire old person that kind do not dread, the relentless spirit, although knows the match strength is very strong, but he not slightly flinches, but is weles difficultly above. Just because had this kind of spirit, the senior fisherman only then achieved this life and death contest suess. We also must study senior fisherman's spirit in life, handles the matter does not fear the difficulty, only then can obtain suessfully.Was reading the big fish's smell of blood is smelled by one crowd of shark fish, struggled swims snatches the food, old person's left hand happen to in the convulsions, he only could use the right hand, with wooden stick， the mouth and so on all was allowed to use for the weapon self-defense which attacked, and finally expelled this crowd of shark fish. But the big fish's meat was already eaten one most, but the old person also charmingly criticized oneselfthe left hand " this work time actually was resting " time, Ialso was subdued by the old person optimistic spirit. In the life, some losses are inevitable, we should treat by the optimistic manner, cannot be calculating.Finally, the novel sees by one youth the senior fisherman fully has 18 foot long big marlin in the measure, once more described this fish's hugeness, explained senior fisherman overes the difficulty was big, non- was more mon than.The novel eulogized the spirit which the senior fisherman fear hard and dangerous diligently did not struggle, we also should like his such, could not satisfy the present situation, should positively to above, do any matter all is relentless, meets difficultly must wele difficultly above, could give up halfway in no way. Only has this, we only then can obtain a bigger suess and the victory.4.雾都孤儿To Regain the Nature of Goodness-- Review of ‘Oliver Twist’Oliver Twist, one of the most famous works of Charles Dickens’, is a novel reflecting the tragic fact of thelife in Britain in 18th century.The author who himself was born in a poor family wrote this novel in his twenties with a view to reveal the ugly masks of those cruel criminals and to expose the horror and violence hidden underneath the narrow and dirty streets in London.The hero of this novel was Oliver Twist, an orphan, who was thrown into a world full of poverty and crime.

大学英语读书报告范文Reading is an essential part of our college life, and it is especially important for us to read English books to improve our language skills. Today, I would like to share with you my reading experience and thoughts on the book "To Kill a Mockingbird" by Harper Lee."To Kill a Mockingbird" is a classic novel set in the American South during the 1930s. The story is narrated by a young girl named Scout Finch, who lives with her brother Jem and their widowed father Atticus. The novel deals with serious issues such as racism, injustice, and moral growth, and it has left a deep impression on me.One of the most striking aspects of the book is its portrayal of racial inequality. Through the trial of Tom Robinson, a black man accused of raping a white woman, the author exposes the deep-seated prejudice and discrimination in the society. Atticus Finch, who serves as Tom's defense lawyer, stands up for what is right and teaches his children the importance of empathy and understanding. This part of the story made me reflect on the racial issues that still exist in today's world and the importance of standing up for justice.Another theme that resonated with me is the loss of innocence and the coming-of-age journey of the main characters. Scout and Jem experience various challenges and learn valuable life lessons throughout the novel. Their interactions with Boo Radley, a reclusive neighbor, and their observations of the town's social dynamics help them grow and mature. I found their growth process to be both touching and thought-provoking, as it reminded me of my own experiences and the lessons I have learned as I navigate through life.Moreover, the book's rich and vivid descriptions of the Southern town and its inhabitants brought the setting to life for me. I could almost feel the sweltering heat of the summer, hear the sounds of the streets, and visualize the distinct personalities of the characters. The author's masterful storytelling and attention to detail made the reading experience truly immersive and captivating.In conclusion, "To Kill a Mockingbird" is a powerful and timeless novel that addresses important social issues and explores the complexities of human nature. It has broadened my perspective and deepened my understanding of the world. I would highly recommend this book to anyone who is interested in thought-provoking literature and compelling storytelling.In summary, "To Kill a Mockingbird" has left a lasting impact on me with its powerful themes, memorable characters, and evocative setting. It is a book that I will cherish and revisit in the future, and I am grateful for the insights and emotions it has brought to me. I believe that reading and reflecting on such meaningful works of literature is an integral part of our growth as individuals and as members of society. I look forward to exploring more literary treasures and continuing my journey of self-discovery through reading. Thank you.。

Reading reportPaper title: A new hard rock TBM performance prediction model for project planningMajor: 隧道与地下工程Name: 叶宇航Number: 1530767Several models have been introduced over the years for prediction of hard rock TBM performance.The TBM performance prediction models are mostly based on an empirical or a semi-theoretical approach. Although they have advantages and area of applications, they also have disadvantages, such as CSM model don’t consider the main influencing parameter, NTNU model require special experiments originated from the drilling, QTBM are too complicated. The authors hope to better understand machine-rock interaction and to develop a more accurate model for performance estimate of hard rock TBMs. In order to achieve it, the authors investigate the field data of three main tunneling projects in Iran and Manapouri tunnel project in New Zealand. The data obtained from the projects as before mention including geological and performance parameters, have wide ranges of variations. But these wide ranges of geological and performance parameters helped in developing a more comprehensive TBM performance prediction model which has covered different geological conditions.In general, to justify the use of TBM in any project and for planning purposes, a reasonably accurate estimation of rate of penetration (ROP), daily rate of advance (AR), and cutter cost/life estimate is necessary. But the authors chosen Field Penetration Index (FPI) which is a composite parameter as the machine parameter. In the text, both single and multi-variable regression analyzes were used to investigate relationship between engineering rock properties and TBM performance parameters and finally to develop empirical equation. The analysis of the data obtained from the projects proved that FPI is a suitable machine performance parameter for developing empirical relationships with geological parameters. And multi-variable regression analysis show good correlation between ln (FPI) as response parameter and UCS and RQD as predictors. In conclusion FPI is a good parameter for the evaluation of hard rock TBM performance. Therefore, the authors developed a chart of FPI prediction. This chart can be used for quick estimation of range of values for FPI in grounds with different rock strength and rock quality.Excepts the FPI, the authors also concerned the boreability. Boreability is the term commonly used to express the ease or difficulty of rockmass excavation by a tunnel boring machine. Rock mass boreability depends on a number of influencing parameters including intact rock/rock mass properties, machine specifications and operational parameters. In tunneling projects, ground characteristics or boreability of the rockmass is an important parameter for selecting machine type and specifications. It is clear that proper evaluation of rock mass boreability can also play a major role in machine operation to achieve the best performance. FPI can be selected as an index for categorizing rock mass boreability. Based on the analysis of give projects, the authors defined six rock mass boreability classes, from most difficult for boring or B-0 class(Tough) to easiest for boring or B-V class (Excellent). Considered the relationship between FPI and boreability, the authors give a table of TBM performance estimation in rock masses with different boreability classes.All in all, the paper proposed a simple model to evaluate rock mass boreability and TBM performance range. This model demonstrates that machine performance has been related to two main rock properties (UCS and RQD) and two operational parameters (average cutter head thrustand RPM).These Input parameters of the model are available in the preliminary stages of the tunnel design and planning. From this paper, I have a much better understanding of the estimation of TBM performance and the impact factors of FPI and boreability. And I think the model proposed in this paper can be applied as a useful tool for quick estimation of TBM performance in projects with different geological conditions and machine diameters. And this model is worth using widely.The new boreability classification which based on rock masses characteristics to allow for prediction of FPI values also worth learning. The authors adopt both single and multi-variable regression to analyze the relationship between engineering rock properties and TBM performance parameters. As a result, it obtains a good result. So, I think when we investigate a problem which influenced by various parameters, we can consider not just single parameter but multi-variable regression. In the process of developed model, varieties of charts which demonstrate the relationship between different parameter play an important role. Thus, chart is an important tool for research. In engineering project, theoretical model should be easy to use so that it can play an important role in project planning. So, I think the classes of rock mass boreability defined in the paper is useful to engineering field.。
