In light of recent celebrity photo leaks from their cloud accounts, one major topic at this years China Internet Security Conference is cloud security. People have all heard the term "cloud" so many times, but what exactly is it?

The cloud refers to software and services that run on the Internet instead of your computer. Apple’s iCloud, for example, is a popular cloud service, as well as Dropbox and Google Drive.

The only problem is, when you a file from one device, make sure it’s d from the cloud too. Otherwise, a copy of it will be left in the cloud.

青春是花一样的季节，多姿多彩；青春是多梦的风铃，潇洒活跃。生活在这个五彩缤纷的世界里，任何人对任何上有色彩的事物都抱有着强烈的好奇心。一探究竟的心理往往都可以在人们的身上看到。毕如网络。

网络，网络是什么？又是如何接近我们的呢？

网络，一开始，如果我们不去触摸它，不去认识它，那它也就不会在我们的身上存活。因为网络就像一个绝代美女，一旦她微笑着婷婷袅袅的向我们走来。我们就不可能忽视得了她的存在。她每靠近我们一步，那使人无法抗拒的美就会使我们的心跳加速一倍。而当她终于走近了，我们却看不清她的面目。恍惚之间只看得到一张面皮。那就是网络。

网络它确实是很神奇的。它像百科全书，包罗万象；它像万花筒，变化多端；它像雨后的彩虹，展现出虚幻的美丽；它像软软的靠垫，让人想紧拥在怀中。它可以是任何东西，也可以任何东西都不是——这正是它的魅力所在。

2005年3月日，重庆沙坪坝区回龙坝镇，14岁的罗华，王东，熊海连续48小时在网络游戏《传奇》营造的虚拟暴力社会中度过。当三人迷迷糊糊的沿着铁路线往熊海家走时，又累又饿，就在铁轨边睡着了，突然间罗华感觉到火车冲了过来，他本能地滚下了铁轨，而另外两个同学却被轧过了。事发前，但人在网吧通宵玩网络游戏，其中熊海连续沉湎网吧游戏长达三个通宵。罗华说：“如果不是网吧玩昏了头，我的同学一定会被惊醒，他们就绝不会死”。

想想，就像罗华他讲的一样，如果不是电脑玩昏了头，这样的悲剧能造成吗？

误导青少年的思想和行为，主要是含有淫秽，色情，暴力，凶杀等内容信息方面。因为青少年有着极强的好奇心和求知欲望，对未知事物充满兴趣，由于身心发育尚未成熟，缺乏辨别能力，自制力易受诱惑，并有意识的进行模仿，同时也是引发青少年犯罪原因。

互联网带给人们的是虚拟的世界，但虚拟的互联网却可以带给青少年实实在在的犯罪行为。

导致青少年缺乏社会责任感，在网络的世界里从可以信口开河，却不必承担法律责任和道德谴责，这种默许会在无形中助长这些孩子们撒谎的勇气和胆量，则这种观念容易在现实生活中形成。

不良信息的输入还会常常让学生感到疲劳导致成绩下降，兴趣爱好减少，与同学朋友疏远，反感父母说起互联网等等不良影响。

网络也许是迄今出现的善与恶最完美的结合，因为它所代表的文化特质可以使每个人心中的善或恶发挥到极至。所以我们应该正确看待网络，争取把我们的善发挥出来，拒绝恶魔的到来。

青少年也应该在家庭和学校的监督下了解自己因网络所失去的东西，经常写上网的生活日记，利用有效管理时间的方式找更有意义的事做。

任何事物都有两面性，当然也包括网络。只要我们正确的利用网络，正确的学习网络，那对于青少年的成长只有益每有弊。

如果你爱一个人，那么就让他上网——因为那里是天堂；

如果你恨一个人，那么就让他上网——因为那里是地狱。

青春是花一样的季节，多姿多彩；青春是多梦的风铃，潇洒活跃，在这个花样的季节里，我们应正确看待网络，构现出靓丽的青春，美丽的年华！

[写网络的危害的作文

网络是现代高科技，现代社会离不开网络，但有的网络游戏对青少年产生了极大的危害。

网络游戏被现代人称为“电子海洛”，网络游戏不但使青少年成绩下降，影响视力更会使青少年走向犯罪的道路，误入歧途。那些贪婪的制造者，制造出一个又一个看似有趣的游戏，而且让众多网迷沉醉于中，网络游戏使人变成魔鬼，使善良的青少年贬称可怕的刽子手，网络游戏正一步一步的蔓延而来，我们青少年是祖国的未来之花，我们应该用坚定的语言对它说‘不’，有人说网络游戏可以玩，因为它可以让人放松。不错的网络游戏是可以让人放松，但对于没有自制力的青少年来说网络游戏仿佛是毒品，它正无声的侵蚀着我们那幼小的心灵。网络游戏它主要的吸引在于它设置的级别，每个人心里都会有赢和升级的欲望，因为现代人太讲究现实抬爱面子，都希望在同龄人那儿大赞一番，让他们羡慕，在人类里面青少年这种不甘落后的心理现象最大，因为他们没有自控力，一心想着玩和升级，有的甚至昼夜不分的网游戏导致视力严重下降，他们为了自己的一己之私害了被人也害了自己的家人，一步一步走向监狱。

在此我想对那些沉迷与网络游戏的同龄人说：良药苦口利于病，忠言逆耳利于行。不要再沉迷于网络游戏了，回头吧！后面将是大好前程，前进键是万丈深渊。

“Shan Zhai” is the new words to express fake products, people use it to express the highly imitated products, some manufacturers produce the Shan Zhai products to make great profit, but it is so unfair to the customers, they pay so much money in the purpose of buying the genius stuff instead of the fake products. Fake products not only cheats people’s money, but also brings people dangers. Such as the medicine, if people buy the fake one, once they eat it, they will feel uncomfortable and get the illness, the most terrible situation is that they will kill themselves. Fake product is so harmful, though the government has taken some action to ban it, still people sold it, it is the temptation of profit that makes people sold it. What if their relatives have bought the products, so in order to keep people healthy, fake products should be banned.

“山寨”是用来表达伪劣产品的新代言词，人们使用它来表达高仿产品，一些生产商生产山寨产品以此来获取巨大的利润，但是这对于顾客来讲是不公平的，他们花费了这么多的钱，只为了买到真的产品而不是假的产品。伪劣产品不仅欺骗了人们的钱，而且给人们带来了危害。比如药，如果人们买到伪劣的，一旦服用，就会感到不舒服，生病，最严重的情形就是因此失去生命。伪劣产品是如此的有害，虽然政府已经采取了一些措施来禁止售卖，但是仍然有人兜售，他们是抵挡不住金钱的诱惑。如果他们的亲戚买了这些产品，会怎样呢，因此为了人们的健康，不要再卖伪劣产品了。

在现代的社会中科技越发的先进我们变得越来越离不开网络。

我的好朋友就住在我家的对门但我们相见却不再是直接到对方家里而是通过电脑视频或是一起在网络里相约在网上玩同样的一个游戏比谁强。

到了现在我们已经很少见面了，甚至可以说就算是见了面也不知道该说些什么，彼此只有在网络世界才能够那样亲近的做朋友。现实里的我们变得越来越生疏了。

在现代戴眼镜的人比不戴眼镜的人要多但在听妈妈说到的那个过去，我觉得很不可思议，过去的人为什么都不用戴眼镜啊！太奇怪了！近视不应该是很常见的吗？

后来我才慢慢懂得了，因为看书而近视的人很少出现但因为网络世界的大门——电脑屏幕，而近视的人很多。

沉溺于网络不会有任何好处，我想我应该找时间去看看对门家的那位朋友了，尽管我不知道她愿不愿意和现实里的这个我做朋友。

随着科学技术的发展人们逐渐有了高科技的产品，电脑就是其中的一个，现在，几乎家家户户都有了电脑，它带给人们很多的益处，同时也给人们带来了危害。先来说说好处吧，网络的好处可多了，它可以查资料、听音乐、画图、玩游戏、网购，也可以和世界各地的人们沟通、聊天，畅通无阻，像一个大家庭。还可以发电子邮件，只要写完内容、发完邮件后，在2秒种内对方就会准时收到，速度快，不麻烦。还有其他功能，如看视频、打字、聊QQ、看小说、弹键盘钢琴等，功能齐全，应有尽有，给人们带来了不少方便和快乐。

可是，它对人的危害也是有很多的。电脑有辐射，如果看的时间过长，就会得一些小疾病，如视力模糊、产生幻觉、恶心、头痛等。有一次，我的妈妈在网上看小说，连续看了好几个小时，忽然觉得恶心、头痛、迷糊，脊柱酸疼。妈妈受不了，只好下了线。这就是网络的危害啊！如果长期无节制的上网，还能分散注意力呢！上网时间过长，就会沉浸于网络里，分散你的注意力，使你的脑袋变得迟钝，使学习成绩下降。我们班有一些同学，一放学，他们就上网，每天都上好几个小时，结果上课时不专心、老师提问题时反应迟钝，结果考试成绩直线下滑。除了以上危害，还有很多危害，有些不良网站会危害我们的心理健康，如暴力网站、赌博网站等，使青少年的心灵被腐蚀，走向犯罪的道路。电脑虽然是高科技产品，方便快捷，但是它不并是十全十美的，也有巨大的危害，所以我们小学生在上网时，一定要注意这些危害，不能沉迷网络游戏，不进入不良网站，要选择好的网站，合理安排好时间，不浪费宝贵的时间，养成一个良好的网络学习习惯，才能正确的利用网络。

网络能使我们获取信息，网络也能使我们沉醉不醒。

这是一个真实的故事，这个故事就发生在我身边。我有一个哥哥，打小学起，成绩一直不错，次次考试都是前几名，妈妈以他为骄傲，可是，好景不常，上了初中后，我家添了一台电脑，就这样他迷上那个了网络游戏，每天都守在电脑旁。开始，妈妈尝试着去劝说他，想让他认识到迷恋网络游戏的危害，可他听了后，像个没事人一样，依旧我行我素，日子久了，妈妈的劝说就变成了责骂和鞭打，可这对一个正处于青春期的男孩并没有多大的作用，反倒弄巧成拙，妈妈越是责骂和鞭打，他就越反抗。

爷爷身体一直不太好，爸爸又时常不在家，家庭的重担就落在妈妈身上，最近，爷爷的身体越来越不好了，医生说要住院观察，庞大的医疗费也增加了家庭的经济负担。可这些哥哥都没有看在眼里，他依旧玩着他的游戏，哥哥的这些表现使妈妈更加生气，妈妈每天以泪洗面，可哥哥并没有为此发生改变。

网瘾到底有多大的危害呢?竟然可以使一个好学生变成一个问题少年?

网瘾是毒药，他会使人上瘾，他会使人陷在网络游戏里无法自拔。

唰唰，哈哈你‘挂’掉了，杀呀，冲呀，yes，又干掉一个，升级啦!哈哈!”这是小明在玩CS时发出的感叹，他每天一回到家第一件事便是打开电脑玩游戏，再加上他玩这个游戏已经很长时间了，所以他已经成了游戏里的高手了，每天很早就开始玩，熬到很晚才恋恋不舍的从游戏中退出来，随便应付一下作业，第二天好交差;要是下来的太晚，第二天随便找一个借口，又是什么肚子痛，又是什么头痛，有时还说停电了，日久天长，连老师都不信他了，眼看办法没了，只有请假了，但他请假并不是在家补作业，而是接着玩电脑游戏;有时候他母亲回来，他立刻从网上下来，坐在自己的房间，做着作业，他母亲看到他这样，以为他最近这些天来都很乖，并不知道小明这些天来每天都在打游戏，还说：“小明，最近这些天妈妈都不在，你这么乖，而我却没有给你一些奖励，以后一定要好好奖励奖励你!”

当他妈妈走了，他觉着自己的办法很管用，便更加放肆的玩起来。现在的电脑辐射特别厉害，于是，小眼镜也很快的上了他的鼻梁，而且度数越来越高。

小明原来可不是这样，他原来是一个很听话的小孩，考试次次得100分，动不动就获奖。但由于一个坏同学的诱惑，才渐渐走上网络游戏的道路，成绩渐渐下滑，从名列前茅到了中偏下的成绩，然后又渐渐成了班里学习最差的同学，而在远处工作的妈妈却毫不知情。而且，他在学校动不动就跟同学们讨论关于游戏的事情。 放暑假了。这可是小明盼望以久的事情，因为在暑假里，自己可以无忧无虑的玩，玩多久都可以，而他的母亲对他特别放心，很少会回来一趟，只是电话打得比较多，而每次小明都是接电话，欺骗妈妈自己正在做作业。在暑假快要结束的前十天，小明连续打了五天，饿了就吃点剩饭，渴了就喝点白开水，不睡觉，彻夜在网络世界中玩。终于，有一天，小明在玩游戏中不知不觉昏倒了，他的母亲正巧在这个时候给他打了一个电话，可是以往小明都会来接电话，可这一次却没有来接电话，小明的母亲觉得家里发生了一些事儿，于是便立刻回到家，发现小明昏倒在电脑前，而电脑里显示出的是游戏，小明的妈妈立刻抱起儿子上医院。

事后，小明向母亲坦白了事情的一切经过，并决定以后再也不玩游戏了，一定要痛改前非。终于，小明又成了班里名列前茅的同学了。我要向全国还沉迷在网络游戏中的青少年说：“你们快点从网络游戏的虚幻场景中醒来吧，不要沉迷在网络中，不然，你们的良好前途将会被毁掉的!”

网络，是现代科技进步的最好证明，可如果沉迷网络也会造成不小的青少年抢劫、偷窃，甚至是杀人的犯法事件。

17岁少年小新为了偷钱上网，竟然将奶奶当场砍死，将爷爷砍成重伤。事后，小新投案自首。

两年前，小新开始沉浸在网络里，学习成绩陡然下降。初中还没有毕业便辍学。 因担心儿子整天沉迷于网吧，小新的妈妈让他照看家里的台球桌。小新把看台球桌挣的钱拿去上网。后来家里不再提供上网的钱，小新就想到了偷。今年6月上旬，小新偷了爸爸2000多元在网吧呆了一个星期。父亲的一顿打骂对小新来说已经起不到任何作用。

仅仅几天后，上网的欲望又像虫子一样噬咬着他的心。此时，爸爸月初给奶奶生活费时说的一番话浮现出来。“爸爸说爷爷那儿有4000多块钱，当时听了也没太注意，后来就想去偷爷爷的钱。 6月15日中午就去爷爷家，晚上，看爷爷奶奶都已经睡了，就去翻，可一想怕把奶奶吵醒了，就想用菜刀把奶奶砍伤了再翻。” 睡梦中的奶奶倒在了血泊中，响声惊动了爷爷。不顾一切的小新又将菜刀砍向了他。爷爷受伤后逃出家门。小新翻箱倒柜也没有找到那4000元钱，只在奶奶兜里找到了两元钱。事后，小新的爷爷说，那是奶奶为孙子准备的早点钱。小新捏着两元钱在村口的一个洞里躲了起来。想来想去，还是投案自首了。

小新告诉记者，奶奶从小最疼爱他，有什么好吃的都惦记着他。他在看守所里最想念的就是九泉之下的奶奶。“我当时只想着拿到钱后就去网吧，根本没想后果。如果让我在上网和奶奶之间重新选择，我肯定选择奶奶。”说到这里，他痛哭流涕起来。

法制是平衡我们生活的规定条例，可这来源于我们的自制力，只有明白了这一点，才能让我们的家园真正美好。

网络是现代高科技，现代社会离不开网络，但有的网络游戏对青少年产生了极大的危害。

网络游戏被现代人称为“电子海洛因”，网络游戏不但使青少年成绩下降，影响视力更会使青少年走向犯罪的道路，误入歧途。那些贪婪的制造者，制造出一个又一个看似有趣的游戏，而且让众多网迷沉醉于中，网络游戏使人变成魔鬼，使善良的青少年贬称可怕的刽子手，网络游戏正一步一步的蔓延而来，我们青少年是祖国的未来之花，我们应该用坚定的语言对它说‘不’，有人说网络游戏可以玩，因为它可以让人放松。不错的网络游戏是可以让人放松，但对于没有自制力的青少年来说网络游戏仿佛是毒品，它正无声的侵蚀着我们那幼小的心灵。网络游戏它主要的吸引在于它设置的级别，每个人心里都会有赢和升级的欲望，因为现代人太讲究现实抬爱面子，都希望在同龄人那儿大赞一番，让他们羡慕，在人类里面青少年这种不甘落后的心理现象最大，因为他们没有自控力，一心想着玩和升级，有的甚至昼夜不分的网游戏导致视力严重下降，他们为了自己的一己之私害了被人也害了自己的家人，一步一步走向监狱。

在此我想对那些沉迷与网络游戏的同龄人说：良药苦口利于病，忠言逆耳利于行。不要再沉迷于网络游戏了，回头吧!后面将是大好前程，前进键是万丈深渊。

最近，班里又渐渐的有了玩网络游戏的事件，这可怎么办呢？我们该怎么应对呢？

网络游戏，就是在电脑上和很多人一起打得游戏，但是这种游戏却对人造成了很大的伤害，所以还是少玩点为妙。

网络游戏对人的伤害具体有以下三大类：

一,身体伤害：玩电脑多了，很容易近视，此外，如果还沉迷下去，无法自拔的话，就会有严重的伤害，比如说：1、细胞癌化促进作用 2、荷尔蒙不正常3、钙离子激烈流失4、痴呆症的引发 5、异常妊娠异常生产 6、高血压心脏病 7、电磁波过敏症 8、自杀者的增加等身体上的伤害。

二，物质伤害：如果玩网络游戏，要想在游戏里出人头地，可是要下不少“血本”的，在游戏里要想主人公有一把超级武器，一两百块钱人民币是少不了的，还有的游戏更过分，就像“魔兽世界”，居然要每玩一个小时收一块钱！我想，各位那少得可怜的零花钱够花吗？

三，心理伤害：喜欢玩游戏的人，都会出现一个毛病，老是在其他场合上想起游戏，而对自己现在在做的事心不在焉，因此不认真听课，学习成绩就会下降，这个后果是很严重的。

玩网络游戏的伤害多着吧！所以，就此引以为戒，少玩点网络游戏吧。

Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.

Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.

Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.

In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day

everything lives with opposite forces。 the same can be said about modern technology， such asInternet。

at first glance internet offers us excitement and a worl of promise。 frankly speaking， people who have some ideas of it can not deny the merits born with the system。 for instance，it can improve proficiency in scientific research， for by means of it scientists and researchers can get a global look at the latest development in the field concerned and accordingly they need spend no time doing what has already been done。 in view of personal communication， the most convenient means could be peculiar to internet， too。

while people speak highly of internet， its drawbacks shouldnt be neglected。 sometimes， alittle fatal breakdown of the system， or a disastrous error could bring us an enormous amount of damage and loss。 meanwhile， with lnternets replacement of hooks or the written work as the main source of information， humans writing abilities are weakened and relations between people are desalinated。

however， every country on this planet should work hard to develop the system to serve us more efficiently and comfortably， because in the net all countries are interrelated。

雾霾天气是自然和人为污染环境所形成的，面对这种恶劣天气，我们只有采取各种措施尽量避免其给人们正常生活和健康带来的危害。

1.减少外出。抵抗力弱的老人儿童以及患有呼吸系统疾病的易感人群应尽量减少出门，或减少户外活动，外出时戴口罩防护身体，防止污染物由鼻、口侵入肺部，外出归来后，应立即清洗面部及裸露肌肤。

2.减少户外锻炼。雾霾天气气压低，能见度低，空气中悬浮大量尘埃等有毒颗粒，患有支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸道疾病患者，应尽量避免户外锻炼，以免诱发慢性病得发作或加重。同样大雾天气压较低，高血压、冠心病等慢性病患者不宜做户外锻炼，以避免诱发心绞痛、心衰。中等和重度霾天气易对人体呼吸循环系统造成刺激，尤其是在早晨空气质量较差。通常来说，若无冷空气活动和雨雪、大风等天气时，锻炼的时间最好选择上午到傍晚前的空气质量好，能见度高的时段进行，地点以树多草多的地方为好，霾天气时也应适度减少运动量与运动强度。

3. 关闭门窗。由于雾霾天气时，空气中的污染物难以消散，在大雾的天气应紧闭门窗，避免室外雾气进入室内污染室内空气，诱发急性呼吸道和心血管疾病的发生。

4. 注意饮食。患有慢性呼吸道疾病患者，尤其是老年人要保持科学的生活规律，避免过度劳累，多饮水。要注意饮食清淡，少食刺激性食物，多吃些豆腐、牛奶等食品，必要时要补充维生素D。

5.行车走路要倍加小心。中等和重度雾霾天气下，能见度较低，视线差，驾车、骑车和步行的人们都应多加小心，特别是通过交叉路口和无人看管的铁道口时，要减速慢行，遵守交通规则，避免发生交通事故。

As can be seen from the picture, a man with an ax on his right side sitting on a stump just wants to cut the flourishing big tree under the beautiful sunshine when suddenly the tree raises its hand to stop him. What does this drawing intend to tell us? That is to tell us that we should put forward on protecting trees and our forests.

As is known to us,the areas of our forests are becoming sharply less and less.Some selfish people are eager to obtain self-interests from cutting trees ignoring the serious consequences.Trees are humans friends and they are extremely hlepful to us.They are not only bring us shade in hot summer but also prevent cold wind in winter. Whats more importance?they can preserve good soil .Just imagine what would be like if the soil were rushed off leaving only sand instead.Thats very terrible!

To serve as responsible stewards of the planet,we must be awaken to what we are engaging in,we should accacelerate our pace to protect our forests.The Earth that we have is unique,let the fresh flowers bloom on it everywhere!
