英语作文篇1

　　Technology has turned this world into a different one full of wonders, some of them being too good to be true. For example, mobile phone is playing an important role in our social and professional lives, whereas the Internet has connected people at every corner on the planet and beyond. As a consequence, telecommuting may soon become a more common way of working as more people are doing part of their jobs from home. And so what? Actually people are no closer to feeling happy in various respects because such technological developments are destroying many basic values of simple and easy lifestyles. Computers in particular have made life less emotional since the more time people use the Internet, the less time they spend with human beings.

　　In sum, there are reasons to be worried about what will become of mankind as a whole facing an increasingly complex world in which they may enjoy all the conveniences of life and yet they do not feel any happier or wiser. Who knows that over-dependence on modern technology could not mean the beginning of the end of human sparks of creativity, spirit, compassion, love and understanding and other good things about a simple and easy life. In making people's lives more enjoyable but more complex, technology seems as if sending plenty of blessings from heaven as well as sending plenty of evils from hell.

　　计算机英语经典短文：CMS

　　CMS is used to digitally sign or encrypt arbitrary messages. CMS describes an encapsulation syntax for data protection. It supports digital signatures and Encryption. The syntax allows multiple encapsulation, so one encapsulation envelope can be nested inside another. Likewise, one party can digitally sign some previously encapsulated data. It also allows arbitrary attributes, such as signing time, to be authenticated along with the message content, and provides for other attributes such as counter-signatures to be associated with a signature.

　　CMS被用于数据签名或者任意消息加密中。CMS提供了一套用于数据保护的数据封装语法。该语法支持数据签名和数据加密。该语法允许多重封装，所以一封数据信封能被另外一封数据信封所封装。同样的，该语法封装数据的部分数据位可以用来表示被封装数据。也允附加一些属性如签名时间，它和内容信息一起用于鉴别信息;计数器属性，它为其它属性提供计数信息。

　　计算机英语经典短文：XDM

　　XDM is the foundation of XPath 2.0 and defines the Data Model for XPath 2.0 (and consequently XQuery 1.0 and XSLT 2.0, which are both based on XPath 2.0). XDM is built on top of the XML Info set (the abstraction of an XML document), PSVI (type annotations in the XML Info set as the result of XML Schema validation), the simple data types of XML Schema, and additional concepts. The most important additional concept is that of a "sequence", which embraces both simple data types and the XML-derived nodes.

　　XDM是XPath2.0的基础，它定义了XPath2.0的'数据模型(因此XQuery 1.0 、XSLT 2.0也就基于XPath 2.0)。XDM 建立在XML信息集(从XML文档中抽取)和PSVI(作为确认XML Schema结果的XML信息集合的注释类型)的顶端、属于简单的XML Schema的数据类型、是一个附加的概念。其中，它最重要的附加概念就是“顺序”，即包括简单数据类型和XML的源节点。

　　计算机英语经典短文：ABNF

　　Internet technical specifications often need to define a format syntax and are free to employ whatever notation their authors deem useful. Over the years, a modified version of BNF, called ABNF, has been popular among many Internet specifications. It balances compactness and simplicity with reasonable representational power.

　　互联网技术规范经常需要定义一种格式化语法并能自由地使用作者认为是有用的任何符号。多年来，巴克斯范式（BNF）的一个修订版，即扩展巴克斯范式（ABNF），已经在许多互联网规范中流行。该版本平衡了压缩性和简单性，具有合理的表达能力。

　　Nowadays， it is a commonplace that children own startle amount of pocket money. These new moneybags never earned one dollar but had glorious consumptive point of view. As far as I am concerned， we should decrease their pocket money. The reasons can be listed as following.

　　First ， money produce negative effect on children. As I can see， there are few children could make a correct decision on purchasing， especially as the sum of the money is affluent. They always use it in some harmful ways， such as trying to drink and smoke. It is danger both on their physical and mental aspects.

　　Second， parents should change their way to express their love. In China， giving a little money to children is a traditional way to show the love of the adult. With the increasing amount of money that has be given ， some children become a moneybags during one night. In this reason， changing the way to express our feeling is necessary. In order to reduce children’s money as well as the bad influence from money……

　　At last but not least， schools and our society would offer the kids an opportunity to earn money by their labor. The proverb goes : no pay no gain. The junior moneybags cannot image the difficulties to earn money if they never try.

　　From what has been discussed above， we come to the conclusion that we cannot ignore the gradually increasing pocket money of children. Because money would bring pernicious implication on children.

　　For the old generation, they trend to do physical punishment when their children make mistakes. They believe that the best way to educate children is to threaten them and then correct their wrong behaviors. But the old way to educate kids is out of date. It is better to guide children to realize their mistake would bring what kinds of horrible results. The way the adults nurture them decides what personality they will have when they grow up. Violence will not solve problems but only brings more negative sides. So we need to be reasonable instead of emotional.?

　　对老一代来说，他们倾向于在孩子犯错误的时候进行体罚。他们认为教育孩子的最好方法是威胁他们，然后纠正错误的`行为。但是老一套教育孩子的方法已经过时了，最好是引导孩子们意识到自己的错误会带来怎样可怕的后果。成年人培养孩子的方式会决定孩子长大后的个性。暴力不能解决问题，只会带来更多消极的方面。因此我们需要理智而不是情绪化。

　　Children and teenagers love to stay till late hours in order to play computer games or to see their favorite series and they never seem to have enough time during daytime. However, scientists forestall that regular lack of sleep during childhood could deprive one of normal sleep for all their life.

　　Even though doctors don't know yet exactly why we sleep, the use ofsleeping is unquestionable. Its lack brings about disturbances in concentration, lowers work abilities, leads to bad mood and even increases appetite, which can lead to overeating and all of its consequences.

　　Recently, doctors discovered another side-effect of sleep insufficiency. Japanese doctors affirm that if a child is allowed to go to sleep later than 10-11, when he of she is older he will be in a high risk of severe insomnia. Its cause lies in the fact that children don't have their biological clock established yet and, as a result, the habits which are developed when they are 9-12 years old remain for all their lives. More than that, children's biorhythms are so frail that it is enough to sleep only half of the night several times during a week and the biorhythms go wrong. In general, if a child is used to stay in front of a TV or a computer monitor till late hours, in his adult life he of she won't be able to fall asleep when going to bed earlier. It is very complicated to reverse this process.

　　This is the conclusion drawn by the scientists from the Medicinal University from Tokyo, led by doctor Jun Kahayama. They gathered detailed statistics about the way day rhythms of children with different models of behaviour change. They are being regulated by a special area of the brain – nucleus suprachiasmaticus, which, according to doctors, reacts on the quantity of light perceived by the human eye. When the child is exposed to the influence of artificial light during night - be that from the computer or the TV – the brain cannot determine whether the day has ended or not and, thus, doesn't send signals for sleeping. As a consequence, the brain is "reprogrammed" for a later time of sleeping.

　　Scientists also pay attention to the fact that, during the last 5 years, the number of children younger than 11, suffering from different sleep disturbances, has increased by 26 per cent. Their British colleagues also share these concerns: the director of the Center of Sleep Researches in Great Britain, professor Jim Horn, considers that children who are constantly using computers and mobile telephones overexcite their brain during the day and, thus, cannot sleep normally at night.
