Thus the network security becomes more and more important.

There are various reasons of cyber com*r users security awareness. Many com*rs do not install antivirus software and firewall, or can not guarantee the antivirus software updated daily, which give the com*r criminals an opportunity. Second,for illegal money online.

如今人们最重视的是学生的安全问题，只是有关学生的安全新闻，从未停过，如：新疆阿克苏市阿克苏第五小学再次发生xx事故近百名孩子受伤被送往医院，其中4人重伤、2人轻伤；江苏泰兴市泰xx中心幼儿园发生一起伤人事件，一名男子持刀冲入校园，砍伤31人，包括28名幼儿、2名教师、1名保安，其中5人伤势较重。除此之外还有好多鲜红的悲剧。也正应如此，家长们和老师们才更加重视学生的安全。

我不知道是不是全杭州都搞这个活动，但下城区举行了这个活动，这个活动就是家长志愿者。每个学校的班级都要值一周，轮到的这个班级的家长自愿报名，每位家长一个学期轮到一次，主要的工作是协助老师和保安维持学生放学安全。这样的活动过得了家中的认可，每位家长都积极报名，没有哪个家长不愿意来的，这样家长也放心，老师也放心。

除了家长志愿者，我们学校曾多次进行过安全宣传，安全讲座呼吁学生们保护自己的安全，同时也让家长放心、老师放心。

同学们每当你在奔跑时，是否担心过自己的安全，在操场上奔跑时，是否让家长老师放心。我们应该注意自己的安全，保护好自己。我的老师跟我讲过一个故事，有一个学生很调皮，在奔跑时肚子撞到尖角导致脾肝受伤，医生将他的脾切掉了一大半，并告诉他不能在奔跑了。可到了高中，学校老师并不知道这件事，在一次运动会上，这个学生参加长跑，结果供血不足，导致身亡。这个鲜红的教训给调皮的学生敲了敲警钟，也让更多的人感到后怕。

孩子的安危是全家人最担心的。同学们让我们好好的保护自己的安全吧，让老师家长们放心吧！

“加油!”“快点!用百米冲刺的速度!”……为什么大家都这么激动呢?原来是学校在开运动会呢!大家在欢呼雀跃挥舞着彩旗，高声呼喊助威的同时，可可却不见了踪影。他可是最用心、最激动的观众呢，以前，作为拉拉队队长的他每次还自带喇叭给班上的运动员呐喊助威的，然而这一次，他去哪儿了呢?

运动会结束后，我们来到他家。果真，“滴滴”声从他的房间里面传出来，他正玩的不亦乐乎，似乎听不到敲门声。我们只好自己走进去，只见屏幕上面是些暴力游戏，可可继续打他的游戏，疯狂的手指停不下来，一副不欢迎我们到来的样子。牛牛看了看他摇摇头说，这似乎不是他自己了，因为可可脸上写满了疯狂，学习和运动已经成为不了救他的绳索。

叮铃铃……，上课铃声划过宁静的校园，上课了，老师那双大眼睛扫了扫教室，指着可可的座位对同学们说，他由于多次无故旷课，破坏学校财产，伤害同学，不听教育，已经被学校退学了。

As the number of internet users continues to grow worldwide,internet safety is a growing concern for both children and *s. The internet safety, or online safety, is the knowledge of maximizing the users personal safety and security risks on private information and property associated with using the internet, and the self-protection from com*r crime in general.

To begin with, we have to take the information security into consideration. As we all know, sensitive information such as personal information and identity, passwords are often associated with personal property (for example, bank accounts) and privacy and may present security concerns if leaked. Unauthorized access and usage of private information may result in consequence such as identity theft, as well as theft of property.

Whats more, the personal safety cannot be ignored. The growth of the internet gave rise to many important services accessible to anyone with a connection. One of these important services is digital communication. While this service allowed us to communicate with others through the internet, this also allowed the communication with malicious users. While malicious users often use the internet for personal gain, this may not be limited to financial/material gain. This is especially a concern to parents and children, as children are often targets of these malicious users.

How can we deal with the problems in the Internet safety? Actually, we have several preventions. First, keeping shared information at a minimum and safe passwords and PINs are useful. Moreover, wed better strengthen our Social network websites and security software.

Through the use of antivirus software, the user can automatically detect, prevent and remove com*r viruses and various types of malware. Very often it is impossible for the user alone to identify infected files and software until it is too late, especially if the infected file or software is well disguised as legitimate files. Because of this, it is important that the user keeps antivirus software running on the com*r whenever accessing the internet so that the user can filter and block infected files and firewalls.

就拿我来说好了。前一阵子，发现了一款很好玩的游戏，又可以交友，又有虚拟小家，真是让我不亦乐乎!周末一做完作业就躺到床上，拉过鼠标，悠哉悠哉地在虚拟世界里东逛逛西瞧瞧，又是领礼包又是领宠物，还时不时地与朋友聊下天，连妈妈喊我吃饭的声音都像耳旁风似的吹了过去，等到肚子“咕咕”地发出抗议时，才渐渐想起“吃饭”这个词。转头一看，妈妈已经守着冷却了的饭菜，瞪着我好久了。我若无其事地笑笑，迅速拿起筷子东夹西夹，三口两口把饭菜乱吃一通，又坐回电脑前。我发誓我这辈子都没吃过这么快的一顿饭。

有时妈妈劝我：“宝贝女儿，别玩了，看些书吧。”我一听要放下这么好玩的游戏，纵使书有多大的诱惑，还是怒气冲冲地朝妈妈喊道：“不!”妈妈轻叹了一声，眼神里无法躲闪的失望，我还是捕捉到了，但我还是把头撇向了电脑。
