Computers, mobile phones, ipad itouch,mps3, p4, p5, psp.rray of electronic products has become a new generation of young people pet.Children, synonymous with fashion family. However, more and more electronic products charging people raw red,Live serving the same time, some small risks caused quietly.On the physical properties of the surface electronic products made : at present, the world recognized six to human health.The greatest threat to harmful elements , namely, lead Pb, Cd cd, Mercury Hg, hexavalent chromium cr6 +, and morePolybrominated diphenyl ethers PBDE, polybrominated biphenyls PBB. These types of traditional mainstream electronics products will be used.Toxic substances, they unknowingly harm our body mysteriously . Radiation protection, anti-radiation.Shot in recent years, users of the word is more and more electronic products in that it is clear.They have realized that the radiation hazards . Radiation pollution affects the bodys circulatory system , immune,Reproductive and metabolic function , but also a serious cause cancer , and will accelerate the growth of human cancer.Colonization . Radiation can really do , people use these products, using a variety of the world face.Radiation of new products , new products chatter about how to magical effect , production.Manufacturers also make every effort to do , and then constantly updated with new products. However , electromagnetic waves on human.Effect is not a simple question , one can not rule out a slight radiation harmful to human health.Possibilities. And with relevant statistics, because the radiation produced by chronic diseases every yearRise.The negative impact of electronic products is only body? No, adult Leaving aside , at On the growth of young people without a correct understanding , that would be what results ? Can not use words.Declare to the phone , for example, to talk about the growth of the students have what hazards.First, from the physical point of view, mobile phone radiation on long-term adverse physical development of students .University of London Professor Gail and the study of human brain cells, the author pointed out , so that normal rats.Accepted 4 hours of continuous frequency range of mobile phone radiation exposure to radio waves similar after the rats.Brain cells, DNA structures have been signs of damage . Studies have shown that children use mobile phones.When the brain absorbs radiation than adults to be higher than 50%. Integrative Medicine Hospital of Lanzhou.Liangxuan Mei said , there are a lot of young people are using cell phones, thought it was not much of a bodyAffected. In fact , young people s immune systems vulnerable than adults , so more vulnerable to radiation shadowRang . Proved . Mobile phone radiation on young people with brain damage , causing headaches,Memory loss and sleep disorders. And frequently play mobile games is also possible for children to deafness, up To 85 db is likely to cause hearing loss.Secondly, the phone in the case of improper use, the impact of the formation of good quality students.In recent years, various types of examinations of students cheating using a mobile phone is not new. 2004 6 May my school final examination found that individual students use mobile phones to cheat; 2004 in Hubei Qianjiang entrance, stone First, the use of mobile phones have undergone Nanchangosaurus fraud thing, another example, fraud and other white power entrance. With Enhanced popularity of mobile phones with features, the growing use of mobile phones cheating. And doing more To the more subtle, such as the headset strapped sleeves, put your hands near the headset exam pretending to think, real Quality listening through the phone came the answer. Girls are more convenient, some simply wearing headphones .Long hair on the ears and then covered, the invigilator difficult to find. In addition, students have a cell phone lying.Is nothing new. Particularly, some students weariness, obviously in Internet cafes playing games, but he lied in school homework. Some students also to make fun of teachers and students, such as a text message. Regardless Cheating, lying or send false messages are not the manifestation of good faith, if not stop Canadian Proper guidance, the students will form a good quality bring serious harm.The digital products let us lazyThere is a scene for the students that we are too familiar with - playing mobile phone and playing computer all the time and regardless of on class or not. In a whole day of 24 hours, we will spend at least eight hours to face with high-definition mobile phone or computer screen. Todays people use the cell phones and other electronic equipment to complete some work even in the exercise. The most important is that it can help them to pass some time, eliminating boredom.Many people feel this habit is normal no more. Using these electronic devices with some entertainment features to extract the boredom without any harm. However, there are some American scientists who have pointed out that these casual little habits have brought an unexpected side effect: when people make their brain too busy to accept the continuing digital information, they will lose the necessary rest time” for their brain. Do not underestimate the rest time, which is an irreplaceable way that it allows people to better learn and remember information, or hold a thought of a new. In other words, the use of electronic products in a multitasking way is easy to damage the brains ability to learn. Like calligraphy and typing, and now, there will be such a phenomenon - people typing faster and faster while their handwriting is getting worse. Otherwise, todays students are not as focusing on their peers neat standardized font as the past years. A lot of kids think that the chance of handwriting is very little in the future. The only thing they should notice is to write in the line and not care the wording is graceful”. “More exaggeratedly, as long as the time goes, the words we usually come in handy are “disappeared”. And just like my classmates said, After playing for a few years computers, a lot of words they just know, but do not know how to write. As is known to all that the popularizing of computer in life has greatly improved peoples working efficiency. But at the same time, due to have an excessive dependence on the keyboard ,many people have the phenomenon of forgetting words in pen, leaving the computer on the thinking of a short circuit, and growing poor handwriting. In paperless age, handwritten” will really drift away yet?Chinese calligraphy art has always been a proud of the cultural treasures, but this art have gradually appeared in an aging trend. Calligraphy, character assessment, quality word, these fun writing characters are becoming more and stranger for a new generation.May 2011, the Ministry of Education, the State Language Commission released the 2010 Chinese Language Situation Report. The report noted that with the arrival of the information age, the Chinese students abilities have decreased not only in reading, but also in writing. August 2011, the Ministry of Education issued a notice that in the primary and secondary school, it will carry out calligraphy education through curriculum and related activities. The notification requires that the introduction of calligraphy education in compulsory language courses must be in accordance with the requirements of curriculum standards, the calligraphy lesson in three to sixth grade language courses a week for a lesson.In real life, there are more people will not care about their own handwriting degradation or even does not care about they are write wrong. Because the “handwritten era” has passed, the universal keyboard makes most people completing the writing of Chinese characters by known pinyin only.But using this convenient way more frequently will lead to people use the specific wording of Chinese characters become increasingly blurred. Someone made a symptom analysis: because of tying the words along with the computer and the phone so frequently and lacking a sense of handwriting and a sense of writing that the language center of the brain does not produce a stimulating effect and resulting in a temporary amnesia cortex.Technological innovation in the field of communication for people to exchange information with each other, provide emotional r fast delivery.cNair and simple modern means, with the popularization of 3G mobile phones, more and more functions can be rtable completed, in which more and more electronic products for all services, all types of electronic roducts also quietly entered the classroom, students can access at any time in the classroom, information search,However, by phone QQ chat, web browsing, online fiction is increasingly becoming mainstream. Lesson.Classroom often have the phone rings, the student texting, whispering to each other to share their receipt.Interesting information, disrupt classroom order phenomenon has no chance.Students face the dangers arising from the use of mobile phones and the presence of a variety of physical and mental health.Problem has attracted the attention of the community, relying only on the original school education with Germany.Remediation work hard to cope with the situation. In order to change the existing passive state school education, it is necessary to Canton.Pan conduct mental health advocacy and social science education, school education and family education combined,Schools should also increase mental health classes and health education classes, in order to guide students to establish the right people.Health concept, correct and reasonable use of the phone.Digital products to harm our bodyWith the accelerated pace of work and the information appeared in large numbers, the first thing many people will do after their get up is to open their mobile phones software and glance at the daily news. Many people like sending a message when they are walking or using a mobile phone or iPad for watching movies, playing games, reading e-books on the bus. In this regard, some experts pointed out that using a mobile phone while walking is usually make people look down at the screen hardly and made the neck, the shoulders and the spine under enormous pressure and reduced the blood flow, the poor blood flow will make the neck, shoulders and spine stiffness and pain, and even inflammation. In addition, looking at the screen in unstable state is easy to cause eye dryness and fatigue and to affect vision thereby. And this behavior can lead to not hear car horns or not see stairs and the traffic accidents will happen easily.Besides, many people have dependency to the digit products with the popularity of microblogging. Not only during the day time stop using all fragmented they will not only interstice of time in daily life to brush the microblogging ceaselessly , but also open the microblogging at bedtime to see if anyone interaction uncontrollably. This kind of update make the time difficult to be controlled down. Some people made a rough estimate microblogging dependency syndrome patient who has reduced the sleep time at least three hours for playing phone.A recent study shows that most people forced out after a day of technology products, will feel severe psychological and physiological discomfort , panic, confusion and extreme loneliness after be forced out to the technology products a day. These symptoms are very familiar with the feeling ofdependent user who abandon drug habits or quit smoking unexpectedly, which is called high tech addiction disease.Though digital products has brought us convenience, but also let us getting lazy, the more worse is it will bring harm to our body. A cancer research expert of UK recently reached an astonishing conclusion: the number of deaths due to use of mobile phones will surpass smoking victims. This is so far the most serious warning that the phone will probably bring harm to our health. Community mobile phone users have reached three times as much as the number of smokers. Therefore, Khurana believes that mobile phones have more serious harm than cigarettes. There are 500 million people worldwide die of smoking-caused each year currently. Today, mobile phones are no longer a simple conversation tool, but also an entertainment device including a function of MP3. According to the U.S. Centers for Disease Control and Prevention data show that 12.5 percent of children and adolescents (6-19 years old) and 17% of adults (20-69 years old), approximately 30 million people, have been caused permanent hearing damage due to excessive noise. In normal conversation, the voice is 60 decibels, 85 db may damage hearing and MP3 sound from the headphones up to 100 decibels.The intuitionistic effect that playing computer has brought is playing games. Pros and cons of playing electronic products have both advantages and disadvantages, but in general, there is more harm than good. The game in electronic products can enhance our practical abilities, which is favorable aspect. However, the disadvantages of playing electronic products are far greater than the benefits. The main reasons are that with the electronic products screen brightness and contrast always change, taking a long time on screen will have the result that a man who has long lifted his arm and makes his muscles stiff. Similarly, because irrational contrast, brightness, flashing electronic screens, people closing look at an object will make the ciliaris move frequently and cause eye fatigue. , if work over time, the ciliaris will spasm and cause pseudo-myopia. If pseudo myopia receives treatment timely in 1 to 3 months, it can restore normal vision. But it will evolve into a true myopia soon if the treatment posterior to the best period.With the continuous development of network technology, science and technology popularization of electronic products, communications creatorNew, more and more electronic products appear in life, for people to exchange information with each other, passingEmotion provides a quick and simple modern means. To build an immeasurable level of economic developmentTaiwan; however, people enjoy electronic products has brought us a new era at the same time, is not s also to think about how to properly use to play the biggest role, and the negative impact.Minimize the impact. How to make our next generation of electronic products for the right to work, study.And entertainment, rather than indulging in online novels, online games, chat? HowBetter use of this double-edged sword? Hope that more students to the right face, the right to make.With the hope that my article you can have alerts.To our knowledge broaden our horizons a reasonable right to use your hands electronic products.翻译： 电子产品充斥我们的日常生活中，你有什么感想呢？ 与当代学生一起成长起来的电子产品，不容质疑的推动了新一代年轻人对新知识的学习和积累，在产生正能量的同时，也不可否认给众多的新新人类的生活产生了负能量。计算机，手机，ipad itouch，ps3，p4，p5，psp。琅满目的电子产品成了新一代年轻人的宠儿，时尚一族的代名词。然而在越来越多的电子产品充赤着人们的生活，为人民服务的同时，一些微小的隐患也悄然而致。 就电子产品的物理属性面言：目前，世界公认的六类对人体健康威胁最大的有害元素，分别是铅Pb，镉cd，汞Hg，六价铬cr6+，多溴二苯醚PBDE，多溴联苯PBB。传统主流的电子产品都会用的这几类有毒物质，他们在神不知鬼不觉的危害着我们的身体。防辐射，防辐射，近年来，这个词被越来越多的电子产品的使用者在说，很明显人们已经意识到辐射的危害。辐射污染会影响人体的循环系统、免疫、生殖和代谢功能，严重的还会诱发癌症、并会加速人体的癌细胞增殖。真的能防辐射吗，人们在使用这些产品的同时，采用各种世面上防辐射的新产品，新产品也喋喋不休的讲述着如何神奇的功效，生产商也在尽一切力量在做，再不断更新新产品。然而，电磁波对人类的影响并不是一个简单的问题，人们不能排除轻微辐射对人类健康有害的可能性。并且具有关部门统计，因为辐射产生的慢性疾病每年都在上升。电子产品的负面影响仅仅是身体吗?不是的，成人暂且不说，处于成长的青少年如果没有正确认识，那会是怎样的结果?无法用文字述说，以手机为例，谈一谈对成长中的学生会有怎样的危害。首先从身体角度出发，手机长期的辐射对学生的身体发育不利。伦敦大学研究人类脑神经及细胞的盖尔教授撰文指出，让正常的白鼠连续接受4小时频率范围与手机辐射近似的无线电波辐射后，白鼠的脑细胞，DNA结构均有被破坏的迹象。有研究表明，孩子在使用手机时，大脑中吸收的辐射比成年人要高出50。兰州中西医结合医院的梁宣梅说，现在有很多青少年都在使用手机，以为这对身体没多大影响。其实，青少年的免疫系统比成人要脆弱，所以更容易受辐射影响。事实证明。手机辐射对青少年脑部神经造成损害，引起头痛，记忆力减退和睡眠失调。而频繁玩手机游戏也有可能使孩子耳聋，达到85分贝就有可能损害听力。其次，手机在使用不当的情况下，影响学生良好品质的形成。 近年来各类考试学生用手机作弊已经不是什么新鲜事。2004年6月我校期末考试发现个别学生用手机作弊；2004年高考在湖北潜江，石首，南漳都发生了利用手机舞弊的事，再如电白高考舞弊案等。随着手机的普及与功能的增强，利用手机作弊现象日益增多。而且做得越来越巧妙，如将耳机绑在袖子里，考试时将手靠近耳机佯装思考，实质在听通过手机传来的答案。女生则更方便了，有的干脆将耳机戴在耳朵上再用长发遮住，监考老师很难发现。此外，学生打手机说谎也是司空见惯的事。特别是部分厌学的学生，明明在网吧玩游戏，他却谎称在学校复习功课。有的学生还以短信方式捉弄老师同学等。无论是作弊，说谎还是发虚假短信都是不诚信的表现，如不及时制止和加以正确引导，会对学生良好品质的形成带来严重危害。数码产品让我们懒惰对于学生，有这样熟悉的场景无论在不在课堂，大家都在玩手机或玩电脑。一天24小时，我们至少花了8小时来面对高清手机或电脑屏幕。现在，人们配备移动电话和一些其他的电子产品，并以此来完成一些工作甚至运动。重要的是，这些产品确实帮助了一些人熬过了无聊的时间。很多人都觉得这种习惯再正常不过了。使用这些电子设备来进行一些娱乐活动，消除一下无聊，这不会有什么伤害的。然而，还是有些美国科学家提出了这些休闲小习惯带来了意想不到的副作用：人们持续地接受数字信息使他们的大脑太繁忙，这样他们将失去必要的大脑“休息时间”。不要小看休息时间 ，这是一个不可替代的，它可以让人们更好地学习和记忆的信息，或持有的一个新思路。换句话说，在一个“多任务处理”的方式使用电子产品很容易损伤大脑的学习能力。像书法和打字，现在，会有这样一个现象人们打字更快，而他们的笔迹越来越差。否则，今天的学生是不会专注于他们的同龄人整齐规范的字体，就像过去那样。“很多孩子认为在将来手写的机会很少。他们应该注意到的唯一一件事就是写成一行但不关心的措辞优美，更夸张的是，只要随着时间的推移，我们通常会派上用场的话是“失踪” 。而且就像我的同学说的：“打了几年的电脑，很多的话，他们只知道，但不知道怎么写。”众所周知，计算机在生活中的普及，极大地提高了人们的工作效率，但与此同时，由于人们有“键盘”上的过度依赖，很多人都忘了钢笔字，离开了计算机就会思维短路，同时有越来越多的人写得一手难看的字。在“无纸化”时代，“手写”真的会渐行渐远了吗？中国书法艺术一直是一个骄傲的文化瑰宝，但这种艺术已逐渐出现了一个“老龄化”的趋势。对于年轻一代人来说，这些有趣的文字的特点和意义正在变得越来越奇怪。2011年5月，教育部，国家语言文字工作委员会发布了2010年中国语言生活状况报告。该报告指出，随着信息时代的到来，中国学生的能力都在下降，这并不仅仅是在读书方面，也在写作这方面。 2011年8月，教育部下发通知，在小学和中学将开展书法教育通过课程及相关活动。通知要求，必须按照课程标
