① 高中生英语演讲关于电脑或者网络的（在线等）3分钟
A computer is a machine that manipulates data according to a set of instructions.
Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". The embedded computers found in many devices from MP3 players to fighter aircraft and from toys to instrial robots are however the most numerous.
The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a mobile phone to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.
Programming languages provide various ways of specifying programs for computers to run. Unlike natural languages, programming languages are designed to permit no ambiguity and to be concise. They are purely written languages and are often difficult to read aloud. They are generally either translated into machine code by a compiler or an assembler before being run, or translated directly at run time by an interpreter. Sometimes programs are executed by a hybrid method of the two techniques. There are thousands of different programming languages—some intended to be general purpose, others useful only for highly specialized applications.
Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre.
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. This effort was funded by ARPA (now DARPA), and the computer network that it proced was called the ARPANET. The technologies that made the Arpanet possible spread and evolved.
In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an indivial computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.
The need for computers to work well together and to be able to exchange information has spawned the need for many standards organizations, clubs and societies of both a formal and informal nature.
电脑是一台操纵根据指令集的数据。
虽然电脑机械事例，通过记录的人类历史上存在很多，首先开发了电脑在20世纪中期（1940年至45年）。这是一个大房间的大小，功耗一样，数百现代（PC）的个人电脑。关于集成电路的现代计算机的倍比早期的机器能够十亿百万美元，占据空间小部分。简单的电脑足够小，能够装到手表，并且可以通过手表电池供电。在各种形式的个人电脑是信息时代的图标，并且大多数人认为是“电脑”。在嵌入式设备中发现的许多MP3播放器到战斗机，从玩具到工业机器人的电脑但最多。
能够存储并执行指令的列表称为程序使电脑非常多才多艺，他们的区别计算器。教会-图灵论题是这种多功能性的数学声明：任何一个有某些最低限度的能力的电脑上，原则上执行相同的任务，任何其他电脑可以执行的能力。因此，从电脑手机到超级电脑都能够完成同样的计算任务，足够的时间和存储容量。
编程语言提供了指定的电脑程序运行的各种方法。与自然语言，编程语言的目的是不允许任何含糊和精简。它们是纯粹的语言文字，而且往往难以朗读。他们一般都翻译成机器代码编译器或汇编程序运行之前，或翻译，直接在运行时由一名翻译的时间。有时候程序执行的是两种方法混合方法。有许多不同的编程语言成千上万的一些拟通用，其他人只需要高度专业化的应用非常有用。
电脑被用来协调20世纪50年代以来，在多个地点的资料。美国军方的SAGE系统是第一个大规模实施这些制度，这导致了特殊用途的军刀等商业系统的数量规模的例子。
在20世纪70年代，在研究机构的电脑工程师在美国开始他们的计算机连接在一起使用电信技术。这一努力是ARPA的资助（现在DARPA）的，以及计算机网络，它被称为产生了ARPANET。该技术取得了ARPANET可能扩散和演变。
随着时间的推移，以后的学术和军事机构网络化，成为称为电脑互联网。网络的出现，涉及的性质和计算机边界的重新定义。计算机操作系统和应用程序进行了修改，包括能够定义和访问网络上的资源，如其他计算机外围设备，存储的信息，等等，为扩展名的个人电脑上的资源。开始时，这些设施主要是人们可以在高科技环境中工作，但在20世纪90年代申请的蔓延，如电子邮件和万维网，与发展经济结合起来，如以太网和ADSL网络技术的快速看到电脑联网变得几乎无处不在。事实上，该是联网的计算机数量正在飘洋过海。个人电脑的一个非常大的比例，定期连接到互联网来进行交流和接收信息。 “无线”网络，往往利用移动电话网络，意味着网络正在成为即使在移动计算环境日益普及。
对于电脑需要很好地协同工作，并能够交换信息促成了许多标准组织，俱乐部和双方正式和非正式性的社会需要。

现代生活中，随着电脑的普及，每个人都在“玩”电脑，但”玩法”却不尽相同：有的人利用网络查阅资料，有的人在网上发表自己的作品，有的人在网上购物……,而对学生而言，最引人注目的,就是那一个个使人着迷的游戏了。
游戏的种类繁多，这些游戏让我们浮想联翩，让我们快乐，但同时也让我们脑袋里充满了幻想而不能专心于学习。
班上有一些同学学习成绩不好，但偏偏游戏玩得好，这说明他们是把学习抛到脑后，游戏放在首位的。课间休息，这些同学总是三五成群的聊着天，可聊的全是游戏的话题，问的都是“你几级啦？”、“最近又发现什么好玩的了”等等。你看，同学们都把自己认为是最宝贵的课间休息给游戏利用了，游戏难道还不可怕吗？

参考范文：
In my opinion，the Internet is helpful rather than harmful as someone else thinks. As is known to all，the Internet is playing a more and more important part in our daily life. On the Internet，we can read news at home and from abroad and get as much information as we can. We can send e - mails or make phone calls to our family as well as to our friends. We can also attend the net school，read many books and even teach ourselves English. We can also enjoy music，watch matches and play computer games on the Internet. We can even do shopping on line. Besides，we can improve our ability to operate the computer.
But we should not be given to the Internet，or we'll get our life and study destroyed. Besides，we should keep off the harmful websites. Anyhow，this doesn't prevent the Internet becoming our friend. We can't throw away the apple because of the core，can we？
网络的利与弊
Internet is playing an important role in our daily life nowadays. Just as a coin has two sides, internet also has both advantages and shortcomings.
网络现在在我们的日常生活中发挥着越来越重要的作用。就像一个硬币有两面，网络也有它的利与弊。
Let’s look at the advantages first. Many of us send emails on the net to keep in touch with others. We can read newspapers and magazines or even enjoy movies on line without leaving our home. We may use the internet to play games for recreation. To conclude, internet has become a part of our life.
让我们先看看益处。我们中的许多人都在网上发邮件以和他人保持练习。我们不用出门就可以在线看报纸杂志。我们利用网络玩游戏以作娱乐。总之，网络已经成了我们生活的一部分。
There are three points in the disadvantages of internet. Firstly, internet is very addictive and many school children are hooked on it.Secondly, people's privacy is easily violated on the Internet.Thirdly, junk emails are pouring into our email boxes daily.
网络有三点不利之处。第一，网络容易上瘾，而且很多学生都沉迷于其中。第二，在网上人们的隐私很容易遭到侵犯。第三，垃圾邮件每天都充斥这我们的邮箱。
However, I think the fault is not internet itself, but its users. I believe that with the awareness of using the internet rationally, it will help make our life more rich and colorful in the future.
然而，我认为错不在网络，而在于使用网络的人。我相信在理性使用网络的观念下，在未来网络会使我们的生活更加丰富多彩。
Many people, especially young college students, like pop songs. They hum small tunes all the way to their schools and seem to be never tired of this. Some of them are even mad about pop songs, rock'n'roll in particular. They shout and shout until their voices become hoarse.
Others will submerge themselves in the romance of the love songs, with tears streaming down their cheeks. Despite such popularity of the pop songs, however, some people dismiss such kind of songs as crude and worthless. They hold that these songs are easy to sing and they are usually characterized with simple tunes which lack variety and depth. Based upon this, they say that pop songs should not have gained such popularity. Whereas many others stick to pop songs. Their lives seem to ha ll without songs.
In my point of view, pop songs should not be banned. True, their tunes are simple and sometimes repetitious, but this is not to say that they are of no artistic value. Folk songs are also quite simple in tune but no one could dismiss them as trash songs. There is no denying that some pop songs are equally excellent. Why? Because they are widely sung and widely remembered. For example, "Yesterday" is of high artistic value. No one can deny its beautifulness in tune. Of cours, there are bad songs that will not last long, but pop song fans will give these songs their e by choosing to sing them or not

最是喜爱涧边生长的幽幽野草，还有那树丛深处婉转啼唱的黄鹂。
春潮不断上涨，还夹带着密密细雨。荒野渡口无人，只有一只小船悠闲地横在水面。诗写暮春景物。"独怜幽草涧边生，上有黄鹂深树鸣"。开头二句是写日间所见。暮春之际，群芳已过，诗人闲行至涧，但见一片青草萋萋。幽草，虽然不及百花妩媚娇艳，但它那青翠欲滴的身姿，那自甘寂寞、不肯趋时悦人的风标， 自然而然地赢得了诗人的喜爱。这里，"独怜"二字，感情色彩至为浓郁，是诗人别有会心的感受。它表露了作者闲适恬淡的心境。王安石有"绿阴幽草胜花时"之句，写初夏之景，与此同一立意。首句，写静;次句，则写动。莺啼婉啭，在树丛深处间关滑动。莺啼似乎打破了刚才的沉寂和悠闲，其实在诗人静谥的心田荡起更深一层涟漪。次句前头着一"上"字，不仅仅是写客观景物的时空转移，重要的是写出了诗人随缘自适、怡然自得的开朗和豁达。
接下来两句，侧重写荒津野渡之景。景物虽异，但仍然循此情愫作展衍:"春潮带雨晚来急，野渡无人舟自横"。到傍晚时分，春潮上涨，春雨淅沥，西涧水势顿见湍急。郊野渡口，本来就荒凉冷漠，此刻愈发难觅人踪。只有空舟随波纵横。二句诗所描绘的情境，未免有些荒凉，但用一"自"字，却体现着悠闲和自得。韦应物为诗好用"自"字。"欲啭不啭意自娇"，此写莺啼。"恬然自安流"，此咏百川分流。这类"自"字皆可释为"自在""自然"之意，含有"自我欣赏"、"自我怜爱"的意蕴。"野渡"句当作如是解。舍此，便与一二句相悖谬了。
这两句在结构安排上也很精当。"春潮带雨晚来急"，构成典型环境，与下文形成因果关系;"急"与"自"两字互为照应，准确地传达出诗人内心的情感意识，把客观景物和抒情主体有机地融为一体。状出难写之景，达出难言之情。举世瞩目，汉语成语，拼音是jǔ shì zhǔ mù，意思是指的是全世界的人都注视着，形容影响很大。汉语拼音基本内容的学习在低年级已完成,到高年级时有回生现象,因此有必要引导学生对汉语拼音的基本内容进行复习。其基本内容有声母、韵母、声调、音节等。在复习时要掌握汉语拼音的23个声母，24个韵母，16个整体认读音节和声调，能够准确地拼读音节，会认读轻声，认识大写字母和隔音符号，能背诵默写字母表。具体地说，能看拼音写字词句；能辨认是否整体认读音节，是否该读轻声；能根据词定音，划去不合适的音节；能区别多音字；能按照汉语拼音字母表的顺序排列大写字母，并写出相应的小写字母。除此之外，还应根据本方言的特点，把握学习汉语拼音的重点和难点．如声母中平、翘舌之分；韵母中前、后鼻音之分。对一些常用字的读音应反复拼读，适当记忆。

⑥ 我那时候没有电脑也没有互联网用英语怎么翻译
I didn't have a computer or the Internet at that time
我那时候没有电脑也没有互联网
⑦ 英语短文翻译 We are all busy taking about and using the Internet.
我们总是忙于谈论和使用因特网，但是到底有多少人知道因特网的历史呢？
当发现因特网始建于二十世纪六十年代的时候，很多人感到很惊奇。在那个时候，电脑既庞大又昂贵，而且网络不能很好的运行。如果在网络中的一个电脑崩溃，那整个网络都会停止运行。所以一个新的网络系统必须要成立。新的网络系统必须要可以运用于不同的电脑上。如果网络中的一部分不能工作，那么信息可以通过其他的部分传输。在这种方式下，电脑网络系统可以不停地运行。
最初，因特网只能由政府使用。但是在二十世纪七十年代初期的时候，大学，医院以及银行也可以使用因特网了。但是，电脑仍然昂贵而且因特网也很难使用。在二十世纪九十年代初，电脑变得便宜了，而且更容易使用了。科学家不得不开发软件，使上网变得更加便利。
现在上网是很容易的。据说，上亿的人每天都在使用电脑。在学生当中，发送邮件也越来越受欢迎了。
因特网现在变成了人们生活中最重要的部分之一。
⑧ 英语段落翻译
我们都忙于讨论和使用网络，但是又有多少人了解网络的历史呢？很多人都感到惊奇当他们发现网络是在20世纪60年代建立起来的。那个时候的计算机体型庞大而且价格昂贵。此外，电脑联网运行也不稳定。如果一段联网中有一台电脑瘫痪，那么整个联网系统都无法正常工作。因此必须设立一个新的网络系统。这个系统理应要完善到当部分联网无法工作时，其他众多计算机仍能正常运作。
起先，网络只运用在政府职能中，但在早期20世纪80年代，大学、医院和银行也开始逐渐使用网络。但是，计算机价格仍旧昂贵，并且网络运用很难变的便宜些和易于上手操作。科学家们因此还研究出能够使上网变得更为便捷的软件。
如今，上网变得十分便捷。据说，每天都有成百万的人使用网络。在学生间，互发电子邮件已经变得越来越流行。网络在今天已成为人们生活中最重要的一部分之一。
