The technology which surrounds almost everyone in the modern society, affects both work and leisure activities. Technology contains information that many would rather it did not have. It influences minds in good and bad ways, and it allows people to share information which they would otherwise not be able to attain. Even if a person does not own a computer or have credit cards, there is information on a computer somewhere about everyone. The technology which is just now beginning to be manipulated and harnessed is affecting the minds of small children and adolescents in ways that could be harmful. It is affecting our immediate future. It also gives another form of communication and exchange of information which was not available before, information that is both good and bad.
Technology is one of the principal driving forces of the future; it is transforming our lives and shaping our future at rates unprecedented in history, with profound implications which we can't even begin to see or understand. Many different elements affect how satisfied we are with our lives. The impact of technology on these elements can change how safe, healthy and happy people feel. Throughout history, people have looked for better ways to meet their needs and to satisfy their expectations. Technology has improved the way people feed, clothe and shelter themselves. Technology has also changed other aspects of everyday life, such as health care, education, job satisfaction, and leisure time activities. People have used technology since they first chipped stone blades to improve their hunting. Yet some people call the current age the "Technological Age" because of society's dependence on technology. For the first time in human history, almost all the goods and services people use depend on * products of technology are available to almost everyone in society.

科技對學習的影響(The Effects of Technology on Learning) The technological advances of the last few years have been amazing. Never before have students had such a wide variety of resources to help them in their studies. Those who can take advantage of these resources have the opportunity to learn about more subjects and to acquire more in-depth knowledge. In my opinion, students can indeed learn more and learn more quickly with the help of modern technology. The piece of technology most important as a learning tool must be the computer. Paired with the Internet, it allows students to research topics more quickly and thoroughly and to write up their findings more rapidly as well. Furthermore, advances in many fields are being made so fast these days that it is impossible four textbooks to keep up. Technology allows students to keep abreast of the latest developments. Also, it cannot be denied that many students enjoy using such resources in their studies. Because of this, they are more likely to pursue subjects in greater depth. For all these reasons, I believe that technology is of great benefit to today's students. Of course, it is still possible to learn without the aid of such devices, but I believe that those students who are fortunate enough to have access to technological resources should take every advantage of them. 科技對學習的影響 近幾年來,科技方面的進步相當驚人。
學生從來沒有過這么多各種各樣的資源來幫助他們學習。能夠利用這些資源的人有機會學習更多的課題,并獲得更深入的知識。
依我之見,有了現代科技的協助,學習確實能夠學得更多,而且學得更快。 科技上最重要的學習工具非電腦莫屬。
電腦搭配互聯網的使用,使得學生能夠更快速、更徹底地研究他們的課題,也能更迅速地詳細寫出他們的發現。此外,目前許多領域都進步神速,教科書根本不可能跟得上,而科技讓學生能夠跟得上最新的發展。
并且,不可否認的是,許多學生在學習時也非常喜歡使用這樣的資源。這樣,他們較有可能更深入地研究各種課題。
基于這些理由,我相信科技對現今的學生有極大的幫助。當然,沒有這些設備的協助也是有可能學習的。
但我認為,那些有幸能夠使用科技資源的學生都應該善于利用這些資源。
6.請給我兩篇關于科技的作文
關于科技的作文:科技是把雙刃劍 什么是科學?達爾文曾下過這樣一個定義:“科學就是整理事實,從中發現規律,做出結論。”
的確,人類遵循著這個原則,完成了使人類在理性精神中獲得最高成就的一個又一個任務,揭開了一個個自然之謎,把古人的美好愿望變為現實。在當今社會,科技已經成為推動生產力發展的巨大動力,使社會一步步邁向繁榮。
但是又有誰敢說:科技對人類,對這個世界只有利,從不存在弊?人們不得不承認一點,科技其實是一把雙刃劍。在它給人們的生活帶來美好的同時也帶來的一系列的麻煩。
如核能可以用來發電,卻也可以用來制造原子彈,而且近期日本的核泄漏更是使人惶惶不可終日;醫藥科技的迅速發展雖然使一些曾經無藥可醫的病癥得到“天敵”,卻也使某些抵抗力強的病菌變異,且破壞力遠遠超過以前病菌的破壞力。其實最嚴重的還是人們常談起的環境破壞。
就拿現在幾乎家家都有的冰箱來說,冰箱里的氟利昂就是地球變暖的元兇,它的溫室效應效果是二氧化碳的數千倍。并且,氟利昂亦是臭氧層破壞的罪魁禍首,從而使紫外線增強,危害人類健康。
科技這把雙刃劍帶來的問題就像是生態系統中的食物鏈一樣循環著。隨著科技的突飛猛進,汽車已經遍布世界,石油也就無限量的被開采使用,從而導致了石油危機的問題,讓每個人腦海里都存在著憂患意識。
而且,由于某些國家的石油儲量不多,便彌漫了為保衛石油而戰的硝煙。既然是戰爭,就必然會有傷亡,必然有勝負,而現在社會勝利的曙光往往會傾向于有雄厚的科技實力的一方。
所以,一個惡性循環就此展開。正如愛伊斯坦所說的:“在戰爭時期,應用科學給了人們相互毒害和相互殘殺的手段……” 科技,殘忍的將安琪兒的雙翅剪斷,讓她不再眷顧人類:科技,將大自然的面紗一層層揭開,然后又在她精致的面龐上劃上一刀刀疤痕,讓她對此展開報復。
因為科技,世間也許不再有秘密,科技創造了美好的世界,可是若是人類不能真正的發揮出它的優勢,那它終有一天會毀了它所創造的一切……Technology and lifeScience and technology are the primary productive forces and have been playing a key role in the national economy development. On the one hand, progress in science and technology has promoted economic and social progress greatly. Take the high-speed railway as an example. Firstly, the railway becomes a new engine of booming of regional economic. Secondly, the railway helps to attract a lot of tourists, so that tourism in these cities flourishes. Last but not the least, the load of the existing transportation network can be released to a great extent. On the other hand, with the development of science and technology, such as the operation of high-speed transportation, video phone, webcam meeting, the world has become smaller and smaller. It has long been a tradition for Chinese government to attach great importance to the advances in science and technology. Science and technology has successfully shaped an entirely new image of China on global stage via the two grand world events, 2008 Olympic Games and 2010 Shanghai World Expo. It is strongly advised that young people should devote themselves into the study of science and technology for “better city, better life”。

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 *chnology 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從尺寸大小來說,通常產生物理化學性質顯著變化的細小微粒的尺寸在0.1微米以下(注1米=100厘米,1厘米=10000微米,1微米=1000納米,1納米=10埃),即100納米以下。
因此,顆粒尺寸在1~100納米的微粒稱為超微粒材料,也是一種納米材料。 納米金屬材料是20世紀80年代中期研制成功的,后來相繼問世的有納米半導體薄膜、納米陶瓷、納米瓷性材料和納米生物醫學材料等。
納米級結構材料簡稱為納米材料(nano material),是指其結構單元的尺寸介于1納米~100納米范圍之間。由于它的尺寸已經接近電子的相干長度,它的性質因為強相干所帶來的自組織使得性質發生很大變化。
并且,其尺度已接近光的波長,加上其具有大表面的特殊效應,因此其所表現的特性,例如熔點、磁性、光學、導熱、導電特性等等,往往不同于該物質在整體狀態時所表現的性。
8.急求:關于科技節的英文文章
科技節轟轟烈烈的結束了。
仿佛是剛過完一個喜慶的節日,又仿佛是參加完了一個豐富的學習課程。科技節中各項比賽的設計,我們的同學構思大膽、創新,而且還能兼顧設計的美觀性!這是在院前小學敢為人先,勇爭第一環境的孕育下,同學們所慢慢形成的一種自我的風格。
在“雞蛋撞地球”這個項目中,同學們的設計新穎奇特,而且能巧妙的運用輕質的材料保護雞蛋不受損。在環保時裝設計中,同學們既擔當設計師又擔當模特兒,而且制作這些精美時裝的材料都是運用一些平日里不起眼,被我們認為是廢品所遺棄的物品,讓我驚訝于同學們的心靈手巧,驚訝于每位設計師們的匠心獨具!同學們都把自己的知識運用于自己的創作中!在科技節中,同學們平日藏在骨子里的潛力盡情的展現出來,就像是火光一般耀眼!我親身參與的是“中國排球永不落”,在比賽中我明白到團隊的合作是很重要的,要完成一個工作,往往需要很多人一同去努力,每個人完成任務中的不同部分,在把這些看似零散的部分合在一起,才能成功。
光靠一個人孤軍奮戰往往不能取得很好的成績。科技節教會我們理性的思維方法,培養了我們的環保能力,也培養了我們的科學素養、與人合作的能力,真是受益非淺!感激老師對我們的悉心指導和幫助,感謝學校為我們提供了這個大舞臺讓我們能自由的發揮想象,自由的讓才華盡現,自由的學習了,成長了。
Science and technology festival ended with vigour and vitality. It is just after afestive holiday, it seems that the attended a rich learning courses. DesignScience Festival in the games, our classmates boldly conceived, innovation, but also beautiful design! This is in pre hospital primary school dare be a person first, inoculation courage first environment, a self style students slowly formed. In the "egg hit the earth" this project, design students of the novel, but also material protection using light egg clever is not damaged. In the environmental protectionin fashion design, the students not only act as designers and act as models, andmaking these exquisite fashion materials are using some weekdaysinconspicuous, we think it is the abandoned waste items, let me surprised the students have clever hands and good sense, surprised at each designers have great originality! The students are applying knowledge of their own in their owncreation! In the technology section, students usually hidden in the bones of thepotential to show out, like the general dazzling! I personally involved in the"Chinese volleyball will never fall", in the game I understand that teamwork is very important, to complete a work, often need a lot of people together tocomplete the task, each person in different parts, in these seemingly fragmentedparts together, to be successful. One person alone fight a lone battle is often unable to obtain good results. Science and technology festival teaches us a rational way of thinking, cultivate our environmental capacity, but also ability of scientific literacy, cooperate with us, really benefit not shallow! Thanks to our teacher's careful guidance and help, thank the school provides the stage for usso that we can imagine the freedom, freedom let the talent show, freedom to learn, grow up.今天,我校以“眼到,手到,發現,創造”為主題,舉辦了首屆科技節。 這天的天氣特別好,好像是為了這次科技節預定的一樣。
我懷著激動的心情來到了學校,同學們的臉上都洋溢著歡樂的笑容。一進入校園,一股“科技風”就迎面吹來,四周掛滿了同學們的科技畫和科技作文。
其中,我還看到了我的科技畫呢!后面參加節目的小選手們也躍躍欲試,想向大家展示自己的勞動成果呢! 科技節正式開始了,本次科技節請到了許多領導參加。等主持人說完了開場白,一位領導宣布:“濟南市小辛莊小學首屆科技節現在開幕!”“嘩!”同學們都報以熱烈的掌聲。
首先是為科技畫和科技作文的獲獎者頒獎,被念到名字的同學欣喜若狂,沒有被念到名字的同學有些失望。雖然我沒有獲獎,但是看到獲獎同學捧著獎狀時開心的笑容,我真是從心底為他們高興。
接著是同學的科技成果展示。大家發明的東西既科學又實用,而且很實用。
其中,最令我感興趣的是一個二年級的小男孩發明的“動力發射器”,不由得讓在場的老師和同學們發出贊嘆。然后表演的是在市級獲得四項獎項的科普劇——《小水滴》。
在小演員的表演和解說同學的解說下,讓大家了解了水滴是怎樣變成雨的過程。其中,還有我們班的小演員呢!咦,怎么一化妝每個人都長得差不多呀?經過我的仔細尋找,終于在最后一排找到她了。
小演員們婀娜的舞姿和動聽的音樂使同學們陶醉,她們表演完之后,贏得了大家熱烈的掌聲。 科技節在大家的掌聲和歡笑聲中落幕,這次科技界讓我們了解了更多科技知識,它會在我的記憶深處畫上一道美麗的弧線。

Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old.不久之前,許多人認為嬰兒的基本需求是食物和保持溫暖干燥.人們以為嬰兒只有到了五六個月大的時候才會開始學東西.Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to identify which experiences can influence healthy development in human beings.然而,美國的醫生聲稱嬰兒在他們出生的頭幾天便開始學習.肯尼迪施萊佛國立兒童健康和人類發展機構是聯邦政府代理機構,他的目標是鑒別那些能影響人類健康發展的經驗.Research scientists at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings該機構的調查科學家們注意到嬰兒很大程度上受環境的影響,如果嬰兒的母親做了什么他們喜歡的事情,這個嬰兒就會笑.嬰兒學著通過微笑來愉悅母親或者監護人來達到得到最好的照料的目的.這就是嬰兒如何學習與他人聯系交流的方式.。
10.英文科普短文
The Internet is a giant network of computers located all over the world that communicate with each other. The Internet is an international collection of computer networks` that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U.S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic "conferences" with distant colleagues for purposes that had nothing to do with the military industrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it). Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users "On the Net". The Internet is the largest repository of information which can provide very very large network [參考譯文] Internet是由位于世界各地相互通信的計算機連接而成的巨大的計算機網絡。
Internet是計算機網絡的國際性的集合,這些網絡都符合具有地址和命令的標準體系,并經骨干網連在一起。Internet始建于1969年,當時美國國防部為連接少數幾所大學和協議企業而建立了一個全國性網絡。
最初的想法是要增加計算機能力并可由許多地點的用戶共享,并且通過提供用戶間多條路徑來找到哪一種計算機網絡能夠在核戰或其他災難中幸存。ARPNET(這種全國網絡最初的名稱)上的用戶很快就發現他們可以與遠距離的同事交換消息,并且進行某種目的的電子“會議”,而這些目的與軍事工業企業沒有任何關系。
如果另外一些人在其計算機中存有有趣的東西,得到其拷貝是很容易的事(假定擁有者沒有進行保護)。 幾年間,新的網絡接入使越來越多的計算機加入進來。
在1973年進行了第一次與挪威和英國的國際連接。今天,有成千上萬的計算機網絡和數百萬臺計算機與Internet相連。
Internet發展如此之快以至于沒有人能準確地說出網上有多少用戶。 Internet是最大的信息寶庫,它可以提供非常巨大的網絡資源。
這種網絡資源可分為網絡設備資源和網絡信息資源。網絡設備資源使我們能夠進行遠程計算和通信。
網絡信息資源向我們提供各種各樣的信息服務,如科學、教育、商務、歷史、法律、藝術和娛樂等等。
