Computer Science Computer science (or computing science) is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that describe and transform information. According to Peter J. Denning, the fundamental question underlying computer science is, "What can be (efficiently) automated?" Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describing computations, while computer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to people. The general public sometimes confuses computer science with vocational areas that deal with computers (such as information technology), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones. History The early foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks, such as the abacus, have existed since antiquity. Wilhelm Schickard built the first mechanical calculator in 1623. Charles Babbage designed a difference engine in Victorian times helped by Ada Lovelace. Around 1900, punch-card machines were introduced. However, all of these machines were constrained to perform a single task, or at best some subset of all possible tasks. During the 1940s, as newer and more powerful computing machines were developed, the term computer came to refer to the machines rather than their human predecessors. As it became clear that computers could be used for more than just mathematical calculations, the field of computer science broadened to study computation in general. Computer science began to be established as a distinct academic discipline in the 1950s and early 1960s, with the creation of the first computer science departments and degree programs. Since practical computers became available, many applications of computing have become distinct areas of study in their own right. Although many initially believed it impossible that computers themselves could actually be a scientific field of study, in the late fifties it gradually became accepted among the greater academic population. It is the now well-known IBM brand that formed part of the computer science revolution during this time. IBM (short for International Business Machines) released the IBM 704 and later the IBM 709 computers, which were widely used during the exploration period of such devices. "Still, working with the IBM [computer] was frustrating。
if you had misplaced as much as one letter in one instruction, the program would crash, and you would have to start the whole process over again". During the late 1950s, the computer science discipline was very much in its developmental stages, and such issues were commonplace. Time has seen significant improvements in the usability and effectiveness of computer science technology. Modern society has seen a significant shift from computers being used solely by experts or professionals to a more widespread user base. Major Achievements Despite its relatively short history as a formal academic discipline, computer science has made a number of fundamental contributions to science and society. These include: Started the "digital revolution", which includes the current Information Age and the Internet. A formal definition of computation and computability, and proof that there are computationally unsolvable and intractable problems. The concept of a programming language, a tool for the precise expression of methodological information at various levels of abstraction. In cryptography, breaking the Enigma machine was an important factor contributing to the Allied victory in World War II. Scientific 。

In modern society, we tend to become more and more aware of our living environment or physical environment, because we is not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go. The phoenix Mountain is a place of interest. Every day, it welcome a great many visitors. Years ago, a few people didn`t care about environment protection there. For example, waste paper, plastic bags and tins carelessly disposed could be seen everywhere. A few visitors not only killed animals, caught birds, but also picked up flowers and dug trees. What`s more, some of them set fire for cooking in the woods. People showed a real concern over the problem . And fortunately, measures have been taken to deal with the problem. As a result, the environment there has changed. For example, the visitors take away their rubbish. They do not hunt any more. Besides, people protect trees and all kinds of plants. Futhermore, all the tourists bring their food for lnch by themselves in order not to cause fire. Now ,it is more beautiful than before. We must sing high praise for the good deeds. man and environment the world we live in is becoming more and more intolerable because of environmental destruction. bird flu and sars are two typical examples that environmental destruction may threaten our life. besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather. serious as the problem seems, we can come up with some measures to deal with it. first of all, the authorities should adopt the policy of “sustainable development”, and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing. what' s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. in addition, planting trees helps improve and beautify the environment.。

How to improve your English in full detail (my experience) The Third Edition To be good at English is not particularly easy but not terribly hard either. Before you start to learn sentences, or new words, the first and also the most important step is the "pronunciation". To pronounce perfectly you should buy a tape to assist you to learn and practise. This is the fundamental step to learn English, ignore or pay no attention to this step; you will not learn proper English and you will find the later steps more and more difficult. If you are solid and accurate in pronunciation, you will find the later steps much easier and you will stand firmly on the right track. After mastering the pronunciation perfectly, it is the time to accumulate new words and useful expressions. Of course start from the simplest words like “hello, hi, you, me, he, him, his, her”, etc。
. and expressions like “how are you, how old are you, how do you do”, etc。
. It is essential to write the words on a piece of paper so that you remember them well. Actually everyone had done these at his/her primary school. *************Now let me tell you how I learnt English in China. ******************* Speaking: In China, you won't have enough chances to speak English. What I did was in the morning I got up early and read aloud the texts in the textbooks. The initial aim was to achieve the same speed as the tape, and then being able to read aloud the texts with the same style as the English announcer in the tape. By doing this, it helps you to consolidate your pronunciation and grammar. Listening: Nowadays it is much easier to learn English in China because you can watch some TV channels in English. The more channels in English the better because you can choose your preferred programmes and it helps you to learn English with interests of your own, hence ideal for listening and expression/words accumulations. Writing: It is also very useful to write diaries. On writing diaries, it is not useful if you just write it without the care of grammar and spelling. When you finish you should always read your diaries again to check for errors and refine your sentences (e.g. remove repetitive words, use better expressions, and sort out the structure of the sentences). Reading: It is also very important to read story books in English, starting from thin ones with not many new words. Read as many thin books as you possibly can. Little by Little you will want to read thicker books, and your reading ability will get even better. Putting four elements together: I have to emphasise that when you do all these reading, listening, writing and speaking; you should join them together as a whole, apply the new words you learn from watching TV, reading books to your writing and speaking. The enhancement of learning comes from getting hold of the possible opportunities to speak English (in China or abroad): In China, you should try to go to local English corner to practise your oral English. If you are abroad then you should make a lot of English or international friends so you always have the opportunity to speak English. On Spoken English, attitude is very important. You need to be very keen and you must not be shy. Never be afraid to make mistakes. Always think that a talk in English with some one will help you significantly. You can think in this way: since my parents have paid so much to support me to study abroad, the money is partly spent on the international environment for learning English; therefore I ought to try my best to take every opportunity to practise my English. My English has risen to a higher level in the last 2 years, because I talk in English most of the time. Having some international friends is particularly useful indeed. Summing up the activities: I have also been watching TV too. The real improvement lies in staying with international friends long enough and watching a lot of TV such as news, football, dramas, documentaries etc。
. Writing diaries also helps me to remember good words, good expressions and practise sentence structuring. 文章由 /yylw/ 提供。

Published in 1847, WUTHERING HEIGHTS was not well received by the reading public, many of whom condemned it as sordid, vulgar, and unnatural--and author Emily Bronte went to her grave in 1848 believing that her only novel was a failure. It was not until 1850, when WUTHERING HEIGHTS received a second printing with an introduction by Emily's sister Charlotte, that it attracted a wide readership. And from that point the reputation of the book has never looked back. Today it is widely recognized as one of the great novels of English literature. Even so, WUTHERING HEIGHTS continues to divide readers. It is not a pretty love story; rather, it is swirling tale of largely unlikeable people caught up in obsessive love that turns to dark madness. It is cruel, violent, dark and brooding, and many people find it extremely unpleasant. And yet--it possesses a grandeur of language and design, a sense of tremendous pity and great loss that sets it apart from virtually every other novel written. The novel is told in the form of an extended flashback. After a visit to his strange landlord, a newcomer to the area desires to know the history of the family--which he receives from Nelly Deans, a servant who introduces us to the Earnshaw family who once resided in the house known as Wuthering Heights. It was once a cheerful place, but Old Earnshaw adopted a "Gipsy" child who he named Heathcliff. And Catherine, daughter of the house, found in him the perfect companion: wild, rude, and as proud and cruel as she. But although Catherine loves him, even recognizes him as her soulmate, she cannot lower herself to marry so far below her social station. She instead marries another, and in so doing sets in motion an obsession that will destroy them all. WUTHERING HEIGHTS is a bit difficult to "get into;" the opening chapters are so dark in their portrait of the end result of this obsessive love that they are somewhat off-putting. But they feed into the flow of the work in a remarkable way, setting the stage for one of the most remarkable structures in all of literature, a story that circles upon itself in a series of repetitions as it plays out across two generations. Catherine and Heathcliff are equally remarkable, both vicious and cruel, and yet never able to shed their impossible love no matter how brutally one may wound the other. As the novel coils further into alcoholism, seduction, and one of the most elaborately imagined plans of revenge it gathers into a ghostly tone: Heathcliff, driven to madness by a woman who is not there but who seems reflected in every part of his world--dragging her corpse from the grave, hearing her calling to him from the moors, escalating his brutality not for the sake of brutality but so that her memory will never fade, so that she may never leave his mind until death itself. Yes, this is madness, insanity, and there is no peace this side of the grave or even beyond. Many people in the world are trying to find a perfect companion.Some of these may marry and not know what their new husband or wife is like.This kind of situation often leads to separation or hostility. Other situations may develop between two friends that stem from jealousy, desire for revenge, uncaring parents, etc. Emily Brontë's Wuthering Heights displays several characteristics of destructive relationships. Three of these are uncaring parents, marriage without knowing the person, and jealousy. Uncaring or unsympathizing parents are shown throughout this story to be an element of destructive relationships. Because Heathcliff gained all the attention from Mr. Earnshaw, Hindley became disassociated from his father. This separation continued until after Mr. Earnshaw had died.Another example is between Hindley and Hareton. Hindley became such a drunk and a gambler that he could not properly care for young Hareton. This led to a separation between Hareton and his father as well. One primary example of an uncaring parent is shown between Heathcliff and his son Linton.Heathcliff did not even want his son for anything except enacting a part of his revenge. This is shown by Linton's fear of Heathcliff and Heathcliff's enmity toward his son. Linton even says "。
my father threatened me, and I dread him - I dread him!"(244) to express his feeling about Heathcliff.The hostility and separation between father and son in this book shows that uncaring parents can cause serious damage in relationships with their children. This element of destructive behavior may stem from an unhappy marriage in which the husbands or wives don't know each other. This had happened between Isabella and Heathcliff. Isabella did not really 。

A Brief Analysis of english teaching in senior high school Abstract: Classroom teaching is the main way for students to learn English. But in senior high school, a lots of probelms still exsit in the English teaching especially in the teaching of reading and writing. In this paper, the importance and methods of reading and writing will be further discussed. Key words: reading writing techniques Introduction: Classes should be learner-centered, with meaningful, functional activities, often, classes begin by finding out what the students don't know. These classes operate on the assumption that there is a great deal of information that students lack and that the teacher and textbooks will impact that information to the students. Teachers who hold this assumption view students as plants waiting passively to be fed and watered. But I think the students should be regarded as explorers, active learners who bring a great deal to the learning process and at the same time, draw from their environment as they develop new understandings. The basic principle will be used in the teaching of reading and writing. How to teach reading I. Why teach reading There are many reasons why getting students to read English texts is an important part of the teacher's job. In the first place, many of them want to be able to read texts in English either for their careers, for study purposes or simply for pleasure. Anything we can do to make reading easier for them must be a good idea. Reading texts provide good models for English writing, provide opportunities to study language vocabulary, grammar, punctuation, and the way to construct sentences, paragraphs and texts. Lastly, good reading texts can introduce interesting topics, stimulate discussion, excite imaginative responses and be the springboard for well-rounded, fascinating lessons. The last but not the least, students must read widely because only a fraction of knowledge about the world can come from other experiences in their short lives.II. What kind of reading should students do? When the teachers give reading class to students, they should notice a balance----a balance to be struck between real English on the one hand and the students' capabilities and interests on the other. There is some authentic written material which beginner students can understand to some degree: menus, timetables, signs and basic instructions, for example, and, where appropriate, teachers can use these. But for longer prose, teachers can offer their students texts, which, while being like English, are nevertheless written or adapted especially for their level. Anyway, the materials to be read should be interesting and meaningful. Teachers should become better acquainted with books written specially for teenagers and dealing with their problems.III. What are the principles behind the teaching of reading? i) Permit Students To Read No one has learned to swim by practicing the skills of backstrokes, flutter kicks or treading water while staying on the edge of the swimming pool. Yet, in the teaching of reading teachers often do just that. Rather than let the students into “the water”, teachers keep them in skills books learning rules about letters, syllables or definitions of words rather than letting them into the book itself, permitting them to be immersed in the language which comes from the authors as the readers try to reconstruct the written message.ii) Encourage students to respond to the content of a reading text, not just to the language Of course, it is important to study reading texts for the way they use language, how many paragraphs they contain and how many times they use relative clauses. But the meaning, the message of the text, is much more important. Teachers should help students understand that the main reason to read is for them. They have to have their own purpose to read and reading must make sense, they have to find ways of doing something about it. They should be encouraged either to reread or to continue reading to gain meaning. But they must realize that the meaning is not in the teacher, but in the interaction between the reader and author. Students should be encouraged to ask themselves repeatedly, “Does this make sense to me?” Students should be encouraged to reject and to be intolerant of reading materials that do not make sense. iii) Encourage students to guess or predict Readers' guesses or predictions are based on the cumulative information and syntactic structure they have been learning as they have been reading. Therefore, their guesses are more often than not appropriate to the materials. Students have to realize that risk taking 。

Jane Eyre — A Beautiful Soul Jane Eyre, is a poor but aspiring, small in body but huge in soul, obscure but self-respecting girl. After we close the covers of the book, after having a long journey of the spirit, Jane Eyre, a marvelous figure, has left us so much to recall and to think: We remember her goodness: for someone who lost arms and blinded in eyes, for someone who despised her for her ordinariness, and even for someone who had hurt her deeply in the past. We remember her pursuit of justice. It's like a companion with the goodness. But still, a virtuous person should promote the goodness on one side and must check the badness on the other side. We remember her self-respect and the clear situation on equality. In her opinion, everyone is the same at the God's feet. Though there are differences in status、in property and also in appearance, but all the human being are equal in personality. We also remember her striving for life, her toughness and her confidence… When we think of this girl, what she gave us was not a pretty face or a transcendent temperament that make us admire deeply, but a huge charm of her personality. Actually, she wasn't pretty, and of course, the ordinary appearance didn't make others feel good of her, even her own aunt felt disgusted with it. And some others even thought that she was easy to look down on and to tease, so when Miss Ingram met Jane Eyre, she seemed quite contemptuous, for that she was obviously much more prettier than 'the plain and ugly governess'. But as the little governess had said: 'Do you think, because I am poor, obscure, plain, and little, I am soulless and heartless? You think wrong!' This is the idea of equality in Jane Eyre's mind. God hadn't given her beauty and wealth, but instead, God gave her a kind mind and a thinking brain. Her idea of equality and self-respect impress us so much and let us feel the power inside her body. In my mind, though a person's beauty on the face can make others once feel that one is attractive and charming, if his or her mind isn't the same beautiful as the appearance, such as beauty cannot last for, when others find that the beauty which had charmed them was only a falsity, it's not true, they will like the person no more. For a long time, only a person's great virtue, a noble soul, a beautiful heart can be called as AN EVERLASTING BEAUTY, just as Kahill Gibran has said, that 'Beauty is a heart enflamed and a soul enchanted'. I can feel that how beauty really is, as we are all fleshly men, so we can't distinguish whether a man is of nobleness or humbleness, but fleshly men, so we can't distinguish whether a man is of nobleness or humbleness, but as there are great differences in our souls, and from that, we can know that whether a man is noble or ordinary, and even obscure, that is, whether he is beautiful or not. Her story makes us thinking about life and we learn much from her experience, at least, that is a fresh new recognition of the real beauty.。
