关于科技发展的英语作文

The new century is approaching. It can be expected that there will be a breakthrough in life sceience and space science in the 21st century. First, scientists will conquer incurable diseases through the transformation of genes. With the same technology they can breed new species of animals and even human life in the laboratory. Most important of all, they can decelerate aging and prolong life. Besides, permanent stations will be set up in the moon or other planets or stars so that scientists can make a thorough study of the moon and other planets or star. Most probably life will be found in other stars in universe or the planets or stars suitable for the human existence will be discovered. However, the scientific development will also bring about some social problems. How should we regard from an ethical perspective the one who is bred through the gene technology in the laboratory. How can the police identify the criminal from a group of people with the same DNA? It is quite natural that we will meet problems in the scientific and social development. Therefore, we should be prepared to meet new challenges. 汇众动漫学院 http://sjza.gamfe.com/

English and Me Hi, friends! As you know, the English language is getting more and more important in our studies and lives. Why? Because most people in the world speak English? Because it is one of the five working languages in the United Nations? To be more exact, that's because the English language is used as the world language nowadays. I hadn't ever seen the English alphabet until I entered Hangzhou Foreign Languages School. During my first English lesson, the importance of learning English was clearly explained. I suddenly realized how bright my future would be if I learned English well. I would be able to enjoy English cartoon movies. I would be able to understand English short stories and novels. I would be able to communicate with most foreigners in this world without difficulty. How could all these come true? Textbooks were surely not enough for me because the world today is full of new information. Reading more out of class be-came so necessary. However, the most important was to speak English as much as possible. Just as my English teacher, Miss Hua, always says, ＂We learn English not only for exams. We are studying English to get closer to the world. We read to know more while we must speak to get known, or we can never com-municate successfully. Little by little, I found English a really interesting subject at school. After two years' hard work, now I can speak directly to my American teachers and be fully understood. I can sing beauti-ful English songs at parties. I can exchange ideas with friends on the other side of the Pacific through E-mails. I can even read orig-inal English novels with the help of my dictionaries. See! English means so much to me. I feel incredibly happy about myself too. It has become a part of my life as well. It is true that I am learning about the western countries. Nevertheless, this is not my final purpose of learning English. At school, we have American teachers every semester. During class, they inform us of their culture as well as their country. But out of class, they are more interested in learning about our hometown, our country, our people, our culture and customs. This reminds me to try harder to introduce China to more westerners. I always keep in mind: we are learning about the world and the world is learning about China at the same time. Communication is mutual. English has become a bridge between China and the western countries. Friends! Let's work hard together to improve our Eng-lish 1 Let's practice English wherever and whenever we meet! Let's use English to let the world learn more about China! Come on

The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions. Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable. However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce. Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.可以自己删减在提供一篇翻译的：现代科技使生活更加便捷（Modern Technology Makes Life More Convenient） Modern technology makes life more convenient; tools are the milestores of the technology as well as human being' s progress. Men used to cut trees with hand saw. But now, by using electronic saw they can cut down a tree in only a few minutes. Another example is more vivid: You have something urgent which has to be informed to your friend whose house is two hour's ride away. You probably want to make a phone call. But no telephone is installed in your friend' s home. What could you do? Nowadays, with modern technology advanting, using internet is popular with us. Some years ago, people had to get what they wanted through looking into a lot of information; at last people could become tired and spent too much time. Now, if you use Internet, all becomes a piece of cake. Only by clucking, you will gain what you expect. We all hope that modern technology will reach a higher level, because modern technology makes life more convenient indeed. [参考译文] 现代科技使生活更加便捷现代科技使生活更加便捷；工具是科技进步和人类进步的里程碑。

我们都期待着现代科技能达到一个更高的水平，因为现代科技确实使生活变得更便捷。

21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better. First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently. Also, internet is another useful tool for us today. T...

From size, it usually generate significant changes in chemical and physical properties of small particle size in 0.1 microns (note 1 m = 100 centimeters, 1 centimeter = 10,000 microns, 1 micron = 10 nanometers, 1 nano = 10 ella), namely below 100 nanometers. Therefore, particle size in 1 ~ 100 nanometer particles called ultra fime grain materials, is also a kind of nanometer materials. Nano metal material is the middle of 1980s, then the successful development of field contains nano semiconducting film, nano ceramic, nano CiXing materials and nano biomedical materials. Nanoscale structure material referred to as the nanometer material (nano material), is to show its structure unit size between 1 nano ~ 100 nanometer range between. Because of its size is close to electronic coherence length, and its nature because strong coherent brings the self-organization makes properties change greatly. And, its scale has come close to the wavelength of light, plus its surface with large special effect, thus its display properties, such as melting point, magnetic, optical, heat conductivity, conductive properties etc, often is different from the substance in overall state behavior of nature. Nanoparticles material called utrasmall particle materials from the nanoparticles (nano distinguish) composition. Nanoparticles also called utrasmall particle size, generally means within 1 ~ 100nm between particles, is in atom clusters and macro objects at the junction of the transition region, from the macro and micro usually on the viewpoint, this system not only atypical microscopic system also atypical macroscopic systems, is a kind of typical mesoscopic system, has the surface effect, small size effect and the macroscopic quantum tunneling effect. When people put the macro object subdivided into utrasmall particle (nanometer level), it will display a lot of exotic characteristics, namely its optical, heat, electricity, magnetic, mechanical and chemical properties of solid and bulky than when there will be significant different.Nanotechnology generalized range including nano materials technology and nano machining technology, nano measurement technology, nano application technology, etc. One nanometer material technology focuses on nano functional material production (superfine powder, coating, nano modified materials etc), performance testing technology (chemical composition, microstructure and surface morphology and geophysical, geochemical and electric, magnetic and optical properties, such as heat and). Nano machining technology contains precision machining technology (energy beam machining, etc) and scanning probe techniques. Nanomaterials has certain uniqueness, when matter scale small to certain degree, then have to switch to quantum mechanics to replace traditional mechanical view to describe its behavior, when powder particles size by 10 micron drop to 10 nano, its size is changed for 1,000 times, but converted volume is ten nine 4k times the giant, so both behavior will generate obvious difference. Nanoparticles are different from large physical reason is in the surface area of the relative increase, namely utrasmall particle surface was full of ladder shape structure, the structure with high surface can represent the unrest atoms. This kind of atomic extremely easily with foreign atomic adsorption of bonding, at the same time because narrow particle size and provides large surface activity of atoms. It is melting point, nano powder due to each particle constituent atoms less, surface atomic in instability, make its surface lattice vibration amplitude of the bigger, so has the high surface energy, causing utrasmall particle unique thermal property, also is caused by melting down, as nano powder will than traditional powder easy in low temperature sintering and become good sintering promote materials从尺寸大小来说，通常产生物理化学性质显著变化的细小微粒的尺寸在0.1微米以下（注1米=100厘米，1厘米=10000微米，1微米=1000纳米，1纳米=10埃），即100纳米以下。

因此，颗粒尺寸在1~100纳米的微粒称为超微粒材料，也是一种纳米材料。

纳米金属材料是20世纪80年代中期研制成功的，后来相继问世的有纳米半导体薄膜、纳米陶瓷、纳米瓷性材料和纳米生物医学材料等。

纳米级结构材料简称为纳米材料（nano material），是指其结构单元的尺寸介于1纳米~100纳米范围之间。

由于它的尺寸已经接近电子的相干长度，它的性质因为强相干所带来的自组织使得性质发生很大变化。

并且，其尺度已接近光的波长，加上其具有大表面的特殊效应，因此其所表现的特性，例如熔点、磁性、光学、导热、导电特性等等，往往不同于该物质在整体状态时所表现...

In recent years, people often complain about dishonesty in our society. In newspapers,illegal businessmen run false advertisements to deceive customers. In communication field, some people cheat money by sending false messages. On campus, we find some students cheating at exams. People are wondering why dishonesty is so prevailing? There are several causes,to my mind, contributing to the bad phenomenon. Firstly, some people are money-oriented. They are crazy about improving their material life and forgetting moral sense. Secondly, competition in shopping areas is becoming more and more intense. This forced some people to make profit or attain their goals by false information. Thirdly, some people are eager to become rich overnight. They judge a person's success by the wealth they possess. Finally, school life is full of eternal competition and each student tries to prove that he is more intelligent than the other students. Therefore students cheat on exams to get higher scores. It pays to be honest in the long run. Being honest is beneficial to yourself and to other people,and honesty will bring you true friendship and more business opportunities. As a member of modern society, we should behave ourselves honestly and in return it will pave the way for our success and wealth.Abstract: Nida's ideas on translation have great influence on Chinese translation scholars.

国外百科全书里的，绝对权威.Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it.Textbooks define the field as ＂the study and design of intelligent agents,＂[1] where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success.[2] John McCarthy,who coined the term in 1956,[3] defines it as ＂the science and engineering of making intelligent machines.＂[4]The field was founded on the claim that a central property of humans,intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine.[5] This raises philosophical issues about the nature of the mind and limits of scientific hubris,issues which have been addressed by myth,fiction and philosophy since antiquity.[6] Artificial intelligence has been the subject of optimism,[7] but has also suffered setbacks[8] and,today,has become an essential part of the technology industry,providing the heavy lifting for many of the most difficult problems in computer science.[9]AI research is highly technical and specialized,deeply divided into subfields that often fail to communicate with each other.[10] Subfields have grown up around particular institutions,the work of individual researchers,the solution of specific problems,longstanding differences of opinion about how AI should be done and the application of widely differing tools.The central problems of AI include such traits as reasoning,knowledge,planning,learning,communication,perception and the ability to move and manipulate objects.[11] General intelligence (or ＂strong AI＂) is still a long-term goal of (some) research.[12]HistoryMain articles:History of artificial intelligence and Timeline of artificial intelligenceThinking machines and artificial beings appear in Greek myths,such as Talos of Crete,the golden robots of Hephaestus and Pygmalion's Galatea.[13] Human likenesses believed to have intelligence were built in every major civilization:animated statues were worshipped in Egypt and Greece[14] and humanoid automatons were built by Yan Shi,[15] Hero of Alexandria,[16] Al-Jazari[17] and Wolfgang von Kempelen.[18] It was also widely believed that artificial beings had been created by Jābir ibn Hayyān,[19] Judah Loew[20] and Paracelsus.[21] By the 19th and 20th centuries,artificial beings had become a common feature in fiction,as in Mary Shelley's Frankenstein or Karel ?apek's R.U.R.(Rossum's Universal Robots).[22] Pamela McCorduck argues that all of these are examples of an ancient urge,as she describes it,＂to forge the gods＂.[6] Stories of these creatures and their fates discuss many of the same hopes,fears and ethical concerns that are presented by artificial intelligence.Mechanical or ＂formal＂ reasoning has been developed by philosophers and mathematicians since antiquity.The study of logic led directly to the invention of the programmable digital electronic computer,based on the work of mathematician Alan Turing and others.Turing's theory of computation suggested that a machine,by shuffling symbols as simple as ＂0＂ and ＂1＂,could simulate any conceivable act of mathematical deduction.[23] This,along with recent discoveries in neurology,information theory and cybernetics,inspired a small group of researchers to begin to seriously consider the possibility of building an electronic brain.[24]The field of AI research was founded at a conference on the campus of Dartmouth College in the summer of 1956.[25] The attendees,including John McCarthy,Marvin Minsky,Allen Newell and Herbert Simon,became the leaders of AI research for many decades.[26] They and their students wrote programs that were,to most people,simply astonishing:[27] computers were solving word problems in algebra,proving logical theorems and speaking English.[28] By t
