nowadays, the internet is playing a more and more important role in people’s daily life. however, people’s opinions are still divided on this point.

those who are in favor of the internet claim that it has a lot of advantages. firstly, information searching is no longer a tough job with the help of all kinds of search engines. secondly, we can contact friends or business partners via e-mails or software such as internet meeting and yahoo messenger. last but not least, we can take part in groups or mailing lists to talk with friends of the same interest.

those who are opposed to the internet hold that disadvantages are many. in the first place, the internet costs considerable time, money and energy especially for those with less self-control. in the second place, surfing on the internet for a long time harms the eyes a lot. finally, more and more young people are indulged in online games, internet chat and even pornography, which are extremely harmful to their future development.

all in all, we can safely come to the conclusion that the pros outweigh the cons. the past twenty years witnessed the fast development of the internet along with national economy. a brighter future is awaiting us if we make good use of the internet.

many inventions bring goodness and convenience to our lives. the computer is probably one of the greatest tools invented. according to dictionary.com, the definition of computer is “an electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations.” therefore, it has flexible verities of usages. computers were used for military communications about several decades ago but after it was discovered for more purposes, the true meaning of computer has changed.

people now use computers not only to store data, but also to edit a whole lot more programs and texts than it could before. pc games have changed a lot of kids’ lives. some of them played games, got addicted to them and dropped out of schools because of that; some of them played, got addicted, but after discovering and developing their own skills on such things as computer designing, they became billionaires. however, these people aren’t even 10% of all pc gamers. as the birth was given to computers, the internet hatched after computers. the connections between internet and computer somehow made the attitudes toward computers even worse. because people can share information on the internet through computers, the “information” can’t be all good and proper. besides the fact that people are getting addicted to games or online surfing, violence and pornographies have also become big issues. internet viruses, identity thieves have also caused many troubles to people who use computers. therefore this question has been more and more considered by people: should computers, computer programs, and, most of all, the internet, have more restrictions on people based on their background, ages or other information by the government? or should the internet be like what it is now, or even freer?

many people may argue over the answer for this question. as we all know, restrictions have already been used for many programs such as video games and soft wares. but when internet has been so frequently used by people, very few regulations have be made based on ages. it’s a common problem that most of the internet hackers are teenagers or college students. they hack all different websites, from people’s personal sites to united states national security website. some of them hack websites for money, but most of them do that just for fun. people can hardly do anything to prevent this from happening because all the smart hackers know how to clear or change their ip address to prevent government from tracing them. another key factor for these teenagers to do that is because overloaded confidence. they want to improve themselves by breaking the websites that seem to be impossible to hack. this is obviously illegal and foolish, but it seems a little crucial to put the young talented hackers into jails.

many of the hackers have now been trained officially and are working for either government or large corporations to prevent the damage they have done to the internet. however, not every hacker can be found and trained to be put in good use. internet hacking and viruses should be prevented, not corrected. the reason why teenagers are so addicted to computers is that computers are very much something they can have total access and control of. most of american teenagers have their personal computers, and they most likely have passwords for their computers. first, the passwords give them security of using putting their information in their computers. after internet surfing, some of them might want to do more than just playing games, listening to songs or watching movies on the internet, that’s the beginning of the transformation from an internet surfer to an internet hacker. because there is almost no rules internet and people can surf on the internet as long as they have internet connections. therefore, no matter the age, the internet gives them total freedom of doing whatever, however, and whenever.

more restrictions are the keys to the solutions to this internet hacking problem. such regulations as “internet access registration” can be very helpful to internet security. the way it works is that if a person wants to have internet access with any kind of computer he has, he will have to register to a certain department, and have all his information stored in the system. so every time when he goes online, he has to spend a few seconds, entering his internet id number to confirm his identity. therefore, no matter how he changes his ip address, he and his actions on the internet will still be traced.

identity theft is another problem existing on the internet, thanks to online shopping, people can now buy cloths, books, or even food online. the most common way of online payment is through credit cards and that’s where the problem begins. people’s information on their credit cards can often be stolen by “identity thieves”, they are special thieves that steal accounts and passwords from people without stealing their actual cards. so when you have your credit cards in your hand, it doesn’t mean that you are absolutely safe from identity thieves.

the best solutions for identity theft are both restricted regulations and individual identity protection. for example, in the united kingdom personal data is protected by the data protection act. it covers all personal data which an organization may hold, including names, birthday and anniversary dates, addresses, telephone numbers, etc. technology experts have been developing a new kind of credit cards called “traceable” cards. there is a tiny tracing device inside of the card, so when the card is missing, it’s easy to be traced back no matter if it’s stolen. but if the thieve can steal someone’s information without looking at the card, it requires more than higher technologies. people should also take caution by themselves when they’re asked to give personal information online. for example, when an online shopping site asks you to give your credit card information to them; ideally, before you do anything, you should check if they have the permission from the government of trading goods online.

the following aspects could best illustrate the advantages of internet.netsurfers in different countries can share interesting knowledge and the latest information.besides,internet has provided a major opportunity to buy and sell merchandise .what is more,people may get medical help or even vote on internet.its advantages seem countless.

behind all this glowing talk,however,are some problems.internet makes people passive by stopping them making their own entertainment.so much so that when there is a breakdown or jam,people may find that world wide web turns into world wide wait.what is worse,some children have access to the scenes of violence and sex.apart from these,it can be affected by viruses and hackers.

we should handle its problems,meanwhile we should exploit its potential as well.with proper management of internet people ought to experience more fruits of the information revolution.all the wisdom of the ages,all the information that has enlightened mankind for centuries,should be available to us with the healthy development of internet.

酒的利弊演讲稿篇5

尊敬的老师，亲爱的同学们：

大家早上好!我是高一(理1)班陆宣烨。

今天我演讲的题目是《手机对中学生的危害》。

近几年来，手机，现在似乎成了一种生活必需品，无论是那个年龄阶段的人都越来越离不开手机，他拉近了人与人之间的距离，为人们的生活带来了极大方便。在带来方便的同时，也带来了种.种危害，尤其是对我们中学生。具体危害如下：

1

影响身体健康。

据统计显示，全世界手机用户已达吸烟人数的三倍，手机的危害将比相应的危害更大。经常和手机接触的身体部位受到的影响，如眼睛容易患白内障，皮肤可能导致手机皮肤炎，还会降低人们记忆力等。长期使用手机，容易引发手机依赖症，严重的可能还会导致幻听。

2

影响心理健康。

手机短信，是通讯领域的科技创新，为人们相互交流信息，传递情感提供了快捷而简便的现代手段。然而，有的人却利用它来放纵自己。有部分青少年学生通过手机接触一些不良信息，形成一种心理上不健康的阅读快感。短信过多，会使人心理紊乱，如果手机交流取代了直接交流，会使他们不能接受人与人之间的差异，不懂得尊重别人，这严重影响了同学之间的正常交流。正处在"似懂非懂"阶段的中学生很容易被不健康内容吸引误入歧途。此外，青少年使用手机还容易产生攀比心理，影响了青少年心理健康。

3

易干扰休息，降低学习效率。

相当多的学生使用手机不是为了和父母加强联系，向父母报告学习成绩，而是为了交朋友。24小时同学之间信息发个不停，聊个不尽，学习成绩一落千丈后，他们除了变着法儿向父母要钱之外，其实是很少给父母打电话。每当就寝熄灯后，有的学生就借着迷人的夜色和淡淡的月光用手机和所谓的知心朋友肆无忌惮地说悄悄话，或谈恋爱。有的寝室甚至用手机集体上网到凌晨，导致寝室的同学都无法入睡。一些想读书的学生对此深恶痛绝，苦不堪言。

4

易滋生事端，事故防不胜防。

在很多学生看来，手机简直代表了他们的身份和地位，似乎能让男生更加潇洒多情，能让女生更加有吸引力。由于手机属贵重物品是学生的心爱之物，势必要花费掉许多精力和时间来保管，但还是很容易被偷走，校园丢失手机的现象时有发生，造成了不少的损失和麻烦。

再说，学生们年轻气盛，受不了半点委屈，一旦发生小矛盾，会很快通过手机纠集社会青年前来打架。同时，经常在教室充电，可能会引发触电事故和学校电线线路故障。有的学生由于电话过多，为了交上话费，平时只好省吃俭用或者以学校要交资料费为由向父母要钱，甚至出去做出违法的事情。还会出现少数学生因用手机与校外广泛联系而被人拐骗。

总之，对于中学生来说，手机是弊大于利的，所以我们应该远离手机，作为中学生的我们要严格要求自己。不要让手机影响到我们的学习，从初一开始培养良好的行为和学习习惯。否则，高三、初三的时候就只能对自己说“少壮不努力老大徒伤悲了”。在此，我想对同学们说一句话“勿以恶小而为之，勿以善小而不为”。

我的演讲完毕，谢谢大家。

都说科技造福人类，但唯物辩证法告诉我们，事物都有两面性，类似于手机这样的高科技产品也在不知不觉中为人类带来了一系列负面影响，例如，空调开的时间长了对身体不好，对环境不好，电脑用多了对眼睛不好，对身心不好。因此我认为，被越来越多的中学生随身携带的手机有必要去研究它的利弊。

随着科技的不断进步，手机越来越智能化，多样化，人性化，受到社会上绝大多数人的喜爱。同时，随着人们生活水平的提高，手机的价格也能让大多数家庭所能接受。手机已经不再是有权有势人的“私有财产”。回想90年代初，“大哥大”就像一块大砖头，能配得上它的是和它成正比的重量级人物，它的地位不亚于现在的任何一辆名牌跑车，是所有有权有势的人的重要代表物，谁又能想到，十多年后，手机已是“旧时富人手中机，飞入寻常学生中”。如今的信息发达，中学生们的视野越来越广，开始像成年人一样追求时尚的东西，当下时尚的智能手机成了他们的心上之物，许多家长抓住“天机”以手机作为学业的奖励，或作为节日的礼物送给孩子，这样就造成手机不光在成年人中普遍出现，也在中学生中掀起了一股热潮，中学生玩手机成为一道“亮丽的风景线”。从某种意义上说，手机，已经成为他们生活中极为重要的组成部分。拥有手机的中学生人数也日渐增多，手机的档次也大有水涨船高之势。从最便宜的到价格不菲的能拍照的，各种品牌、各种款式的手机都能在校园里找到它们的拥有者。

中学生有大量的时间是在学校，特别是在校住宿的学生，有的学生会以用来与父母联系的名义把手机带进学校。那么，中学生在校使用手机的到底是利还是弊呢?答案自然是有利也有弊。

其中利有：

1、手机作为高科技产物，确实可以给我们带来许多生活上的方便，学生可以通过手机及时与家长联系，也可以向老师汇报学习等。

2、与以前同学多交流，可以保持原有的友谊;与现在同学多交流，可以增进友谊，遇到疑难问题时，可以用手机进行讨论。

3、一些手机的拍摄功能，可以随时拍下一些有意义有价值的东西。

4、里面的闹钟装置，可以随时使用。

5、通话记录功能，手机不像家里的电话一样不在家的时候别人打电话来不知道，在手机里是有记录的。方便查阅。

6、手机的本身小儿玲珑，占很小的面积可以随身携带。

7、当学生外出游玩或在其他地方遇到危险时可以及时向家长，老师或警察求助。

虽然手机的利有很多，但是它的弊也有不少：

1、短信聊天，影响休息，贻误学业。多数家长反映，孩子用手机谈论学习的内容少，用于同学之间联系或发短信的多。调查的两个班中，甲班成绩明显高于乙班，说明手机必会给学业造成大的影响。

2、不良信息，玷污心灵。据了解，北京市一所中学曾做过一个调查：在学生发送接受的手机短信息中，70%是与正常学习和生活无关的信息，10%以上是黄色短信息，部分学生甚至把相互转发“黄段子”当作时尚。

3、助长学生攀比成风。每到课余时间或放学以后，一些学生就会围在一起，相互“切磋”手的款式和功能。校园里的手机越来越多，档次也越来越高，对那些没有手机的学生很容易造成心理上的不平衡。在攀比之风的影响下，有些学生开始盲目追逐，因为手机更新换代十分迅速，外形、功能都日新月异，学生会炫耀自己的家境，父母地位。这样会让学生把父母当成靠山，不思进取。

4、额外增加父母负担。在学校进行的抽样调查显示，学生购买手机的资金全部直接或间接来自于父母，另外，还有每月几十元到上百元不等的话费也需要家长掏腰包。以一年计算，家长花在孩子手机上的费用至少要500元。对于经济条件并不宽裕的家庭来说，给孩子买手机等于是给家长增添了新的负担。

5、手机为考试作弊提供了条件。本校高20届学生中就曾发生利用手机作弊而被惩罚。用手机舞弊是公开的秘密了，而且一条信息可以发给好几个同学，作弊的范围很广。

6、影响校园治安。手机是贵重物品，若有不良行为的学生会发生偷盗现象。据反映，我校有个别班级出现钱、钱包被盗，手机如果不随身携带，也会被盗。在一些发达国家，学校的管理者比我们更早地遇到了这一问题，手机所带来的恶劣影响也更为突出，已经引发了中学生的犯罪，有手机的中学生也成为一些犯罪分子欺骗和抢劫的对象。

7、使用手机会妨碍学校的教育教学秩序。上课时有的同学手机没有关机，突然来电话，影响全体同学听课。会给整个教室带来不愉快的情绪。本人初三月考时曾因为前座突然来电话而受影响。

8、手机对人有辐射。许多广告只说手机有很多很多先进功能，却从未提对人体伤害。青少年正处在生长发育的黄金阶段，如果因为手机而对身体伤害，岂不追悔莫及。

从上述观点中我们不难发现，中学生在校使用手机的“弊”还是大于“利’的，不少校方都深知手机对学生的危害，所有学生都知道，学校是不允许带手机的，但还是有很多学生偷偷地带，而且声称老师不敢没收他们的手机，原因有：

1、打着家里路远或家长长期在外地的幌子，轻松地从老师手上骗走已被没收的手机。

2、打着“帮派”的名号恐吓知情的同学不告发他们。

3、老师惩戒不严厉，看到学生玩手机只是口头教育，或视而不见，“放虎归山”。

4、家长听信谎话，包庇错误，硬说只不过是由来联系的，反而指责老师不该把事情说严重了。

我认为这些现象都是十分严重的，应该重视。首先一点要明确，学校和家长都是为了学生好，要互相信任，我们作为学生要明白手机的危害，提倡使用校园公共电话，避免携带手机，如果特殊情况一定要带手机回学校的话，要向老师申请，但上课期间要关闭手机或交由班主任保管。
