网络,是我们的高科技的代表;电脑,是人类步入新时代的证明;因特网,是大家便捷沟通的最好工具……

如今,上上网玩玩游戏本是放松心情的好途径,却不想让不少学生玩成了瘾。

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。

有一天,我在朋友的qq空间上闲逛,看了一段视频,是在一座广场,台上站着一位演讲家,下面有众多高中生的父母坐在椅子上,而学生则坐在父母旁。这段视频讲的最多就是报答父母、感恩父母了。教授说的一言一句使在场的高中生扑通跪在了父母身边,留下了两行晶莹的眼泪,模糊不清地喊着:“妈,对不起!”“爸,您受累了!”后面,演讲家也自然讲到了网瘾的问题:“孩子们,网络是工具不是玩具啊!”顿时,我恍然大悟:事到如今,我已把可以汲取大量知识的因特网错当了祸害自己的玩具!现在,为了这一个不真实的玩具,我和妈妈的关系都变得硬硬僵僵的,连个好好说话的时间都被电脑占去了,我这是怎么了呀!我咬着嘴唇,努力地压制着哭声,但还是止不住眼泪的决堤,泪水汹涌地流了下来——我终于明白为什么曾经有了网瘾的孩子改过自新后为什么这么后悔,我想我是幸运的,因为我在没犯下弥天大错前就已经把祸根拔掉了。

从此以后,我再也不迷恋网络了,只是随意地找些小游戏玩,说停就立马停了,而我,最终把那句话深深的烙在心底:网络是工具不是玩具!

篇1:网络的危害

全文共 1216 字

+ 加入清单

董腾飞 206班网络既是近年来热门而有时尚的话题,也是人们各种信息交流的不可缺少的工具,给我们现代化的文化科技等做出了很重要的贡献。21世纪的人们必须要懂电脑,能掌握运用电脑,否则那则是现代科技文盲。任何事物有利但也有弊,这也是事物的必然关系,这样一来种种问题尤然而升,比如说网络游戏,色情网等等一系列的网页,不知危害了多少年华似锦的青少年!

网络游戏的本意可能并不坏,它只是想让人与人之间开辟一块更大的交流空间。可没想到的是,这却诞生了一批又一批的网虫,他们沉迷、于网络游戏的虚幻世界中,整个精神被那激动的情节所吞蚀,仿佛在行尸走肉。一般这些人大多数是缺乏正确理智的青少年,他们无法有分寸的掌握整个网络,而是单单停留在网络游戏寻求刺激﹑寻求荒诞的乐趣中。如果我们在不唤醒这些迷途羔羊,欲待何时呢?2000年就曾发生过一起由网络引起的血案。

一个15岁的男孩,眼看就要中考了,成绩一向优秀的他,由名列前茅竟然下滑,家里人十分担心,怕他考不上重点,再三劝导,问其原因,他始终不肯说出为什么,慢慢的他从第一名一下子落到了倒数几名,他爸爸实在看下去了。有一次,偷偷的跟踪他放学后去干什么了,原来他去网吧了,他爸爸非常的生气,把他捉回了家,痛打了一顿,他心里拗气,离家出走,这一去没有了音讯。本来气氛和睦的家庭一下子冷淡了下来,中考他也没去,原来他一直在网吧,玩着网络游戏,一个网络游戏的奴隶就这样诞生了,很快他没有了钱。于是他回家去要钱,当时他家只有奶奶,奶奶当然不肯给,苦口婆心的劝他这迷途羔羊。谁知,他从厨房里拿了把刀,连捅他奶奶数十下,已至当场死亡,抢走身上仅有的十多元钱……

也许,有人会说:网络也是有益的啊,没错网络对我们的确也有,有益的影响,但负面影响远远大于正面影响,一个个鲜活的事实﹑血淋淋的教训活生生的摆在我们的面前,现在的社会是金钱在主宰,一切市场经济包罗万象。网络也是一样,有多少青少年因为贫穷但迷恋上网而不择手段的想要获取金钱﹗还有网络上那些不健康的东西随处可见,严重污染了青少年的心灵﹗年轻的朋友,该是你们回头的时候了﹗

还有,我在网上查资料时竟发现这样一个惊人的数据,2000年青少年上网率为4.1%,但2003年却变成了25.1%,短短两年的时间里竟多了几百万人上网,而上的都不是一些正规的网站,据统计,近年来每天点击色情网的高达80万人!多么惊人的数据啊!中国有三亿多青少年竟有两亿会上网聊天。这样一来,危害也自然的在大幅度上升,犯罪率也频频上升,有贩毒﹑吸毒,有离家出走的﹑有色情色诱的﹑有搞赌博的﹑有的甚至铤而走险绑架凶杀等等无所不有,无奇不有。有多少人利用网络害人﹑骗人﹗又有多少人因为网络而家破人亡的﹗这些现象不仅是破坏社会风气,还污染青少年的心灵!正如有些人所说:“一个丧失了家庭伦理和社会道德的人,将会是多么可怕啊!

这就是网络对青少年的危害体现所在。如果你好好的利用做有益的事情,网络也会造福于人类的!

“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。

The air we breathe is so freely available that we take it for granted. Yet without it we could not survive more than a few minutes. For the most part, the same air is available to everyone, and everyone needs it. Some people use the air to sustain them while they sit around and feel sorry for themselves. Others breathe in the air and use the energy it provides to make a magnificent life for themselves.

Opportunity is the same way. It is everywhere. Opportunity is so freely available that we take it for granted. Yet opportunity alone is not enough to create success. Opportunity must be seized and acted upon in order to have value. So many people are so anxious to "get in" on a "ground floor opportunity", as if the opportunity will do all the work. Thats impossible.

Just as you need air to breathe, you need opportunity to succeed. It takes more than just breathing in the fresh air of opportunity, however. You must make use of that opportunity. Thats not up to the opportunity. Thats up to you. It doesnt matter what "floor" the opportunity is on. What matters is what you do with it.

篇4:关于英语作文traveling高1

全文共 1227 字

Nowadays, with long holidays at hand,travelinghas become a new trend for

us to relax ourselves outside work. Some people even had made a plan for it a

long time before the holiday begins. They usually travel with good friends or

travel along; only few people take their parents into travel plan. However, I

think it is high time for us to travel with parents.

In the first place, we should spend more time with parents. According to

research, if we come home 5 days a year, spend 4 hours a day with parents, it

would be less than 300 hours of 30 years, which means 25 days. We could see it

now that there is not much time for us to spend with our parents after we go to

work or have our own family. Hence, we should travel with our parents.

In the second place, parents used to took us to travel when we were young,

why don’t we take them as return when we are capable to do that. It is not the

matter of we are set free from parents, we are not a traitorous teenager

anymore, and we have time and money, of course we should take a trip with

parents. Holiday would be a good time for us to travel with parents, just like

the old time.

To summarize, we should make a plan for parents in holiday. Holiday is a

great gift for us and our parents.

网络使人与人之间拉近了距离,聊天软件,电子邮件等等,让我们能于远方的亲人,朋友交流。不仅这样,而且还能让我们跟外地的小朋友交流。有人说:“网络使我们的生活更方便了。”这话一点也不错,是方便了许多,学生回到家里有问题可以上网查查资料,商家可以利用网络做生意,网上购物及方便又实惠,可以说网络使生活方便了许多,但是他也给我们带拉了不利。当这张大网洒向大海之时世界在此不再和平了。许多孩子迷上了网络游戏,整天玩个不停。别说别人了,就在我们隔壁班的一个人,就因为去了网吧一次,迷上了网络游戏,成绩一落千丈。不仅这样,一次我还在电视新闻上,看见一个十七岁的青年,迷上了网络游戏,去网吧家里不给钱后来在家里偷了钱。后来在网吧玩完游戏出来,正沉迷在游戏之中,后来就拿了一把刀,模仿游戏里的动作,在街上看到了一个女孩,有刀子当场把那个女孩杀害,被判无期徒刑。

网络他把我在自己手中,要好好的利用它,不要反而被他利用,为他做奴役。如果好好利用它,它会让你走上成功的道路,如果你被他利用,反而会走上歧途,最后后悔莫及。好了,我希望大家好好的利用网络。

Social Networking’s Influence on College Students

Social networking has gained huge worldwide popularity in recent years, especially among college students. In China, college student is the main force of social networking, 97.7% of which are fond of instant messaging and 80.7% prefer social networking sites like micro-blog and Q-zone (China Internet Network Information Center, 2013). Moreover, Michigan State University Original Study also finds that compared with Chinese students, American students are more tied to social media (2013). Therefore, nowadays there is a heated debate about advantages and disadvantages about social networking’s influence on college students.

Obviously, there are a number of positive features on social networking. It provides a convenient access to consolidate the relationship with people they know, make friends with strangers without restrictions of space and share happiness and sorrow. What’s more, social networking also has educational functions including reducing college drop-out rates, motivating students to work as a team, sending information about assignments, reminding students about deadline and stimulating students to help each other. (BBC News, 2009). There is no doubt that social networking plays a significant role in eiching students’ college lives.

However, every coin has two sides. There are also many disadvantages on the influence of social networking, among which, “soft addiction” is the most serious problem, distracting students from study. Because of lack of self-restriction, many students would waste plenty of time to search the social networking sites unconsciously, followed by a strong tendency to blame themselves (Li, 2013). This kind of “soft addiction” and distraction was also confirmed by Zhang (2011) who conducted a survey by questionare of 500 Chinese college students from different schools and found that 33% students could not bear one-week life without social networking and 77% students could not help themselves accessing social networking site during classes. Furthermore, a social experiment was performed by Harrisburg University (Pilkington, 2010) to figure out the effect after initiating blackout of all social networking sites. It turned out that some students became more concentrated on

the tutor and making notes instead of having instant messaging running in classes.

As far as I’m concerned, the disadvantages far outweigh the advantages, especially in China, where social networking is used for communication and entertainment and seldom plays the educational role (Li, 2011). The priority of a college student is to study hard instead of being addicted to social networking. Therefore, it is imperative for them to realize their “soft addiction” to social networking and correct their behavior.

Nowadays, house husband has become a hot phenomenon in modern society. As

we all know that no matter what country, it’s a tradition that men play a core

role in family who always take the burden to earn money to support their family.

But things are kind of different as society develops, more and more men are

beginning to take over housework while women go out from house. In my point of

view, I think this is not a big deal.

In the first place, house husband may be a shame title for men, but when it

comes to money, there is no room for reputation. As society develops, the life

standard are rising, and everything for living is much expensive than before, if

couples want to guarantee their life quality, then they should let the one who

earn better to work, although the one is female.

In the second place, it’s fine for women to support family as long as they

earn better than men. In the past, women always were treated very badly, and

they got no rights to be educated, to work. In some countries, they can’t even

show their face to others. A traditional female role is to stay at home, taking

care of children and do all of the housework. But now, lots of women have a good

job, so that they totally have the ability to be the economic backbone.

Therefore, in order to take good care of family, men are likely to stay at home

to do housework. I don’t think it’s a shame for men, because no matter what you

do, as long as you do it well, you are successful.

To sum up, people should change their opinion about core role of a family.

It’s acceptable for women to support the family, and there is no shame for men

to do the housework. As long as you remember life quality comes first.

Since we went to school, we have been educated to be polite, no matter to

the young or old people. People follow the manner rules and have a nice

communication between each other, but some people ignore the rules and they

treat their rude behaviors as something cool. Today, people advocate the

individuality, so the young generation wants to do something different and catch

peoples attention. For example, they dont care other peoples feeling and

criticize others as they like, or just interrupt when other people is talking,

they just show what they want to say and they believe they are special and cool.

This is very rude behavior that they dont respect others and have the wrong

idea about individuality. We can do something special on the base of respect

Some of these online languages are represented by several English letters, such as "GG" and "MM", which refer to men and women respectively. There are some homonym, such as "886" means "bye-bye", "94" means "yes", etc. Some use pictures to represent their mood or their expressions, such as ":" to express their happiness.

The rise of online language is conducive to the convenience of information transmission. Because of the simplification of the language symbols, for those who typed unfamiliar, the benefits were not shallow.

However, young people dont understand the meaning of network language, is that they have the language barrier, and even make them unable to communicate, and has part of the network language is a vulgar language, such as "BT" refers to "abnormal" and so on, in one clean and pure heart, wipe off the black spot.

Undoubtedly, the Net are revolutionizing the daily lives of the people who have an access to it. The primary reason behind the Internet boom roots in its multifunction. It provides a vehicle for netizens to shop, search, publish blogs and browse WebPages.

A range of problems lurking behind the frenzy of Internet impressively stand out. A vast majority of Internet users mail boxes are saturated with junk mails, an issue which sparks strong criticism and generates the loss of corporate productivity. Its not alone. Porn websites lure a growing number of young peoples visits. False news via the e-mail, BBS and chat room increasingly poses a threat to the social prosperity and stability.

To crack down them, we should push for a more effectively tough law. We should join our forces to launch a nation-wide campaign, including imposing stiff penalties on spammers, shutting down or blocking the lewd sites and introducing a real-name registration system to curb fraudulent messages. We can fully believe that our combined efforts will reap rewards. A clean cyberspace will paint our lives more colorfully.

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。
