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***,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。
Sometimes I dream about life in the future. What will it be?
Perhaps some people will go to the moon for a holiday or even live on the moon,and some scientists will build cities under the sea to make people live there. We can have a medical examination or do some shopping without leaving our homes,which makes the life more convenient. Maybe we will also do some shopping and work at home.
And I'm sure there'll be more educational programmes on the radio or TV or by the Intemet or videophones,so perhaps some children won't need to go to school every day. They'll study at home.
In the future,all electric equipment at home is under the con-trol of computers. People can learn about the situation of the house by working on the computer at the office. No people like doing housework. Maybe each family will have a robot. Every day we can tell the robot what to do-shopping,housework and so on. believe the dream will come true some day.
these young people are wrong. in my opinion every student should have a knowledge of housework. after all, they will have a family of their own, and they should do their part in keeping a good home. boys should also learn to do housework, for what will they do if they remain single? though not all boys remain single, yet they will be very helpful in the family if they know some housework. anyhow they will not lose anything, but, on the contrary, they will gain something useful.
for what i said above, we can find some eamples of our fellow-students studying abroad. all young men do housework as girls do. someone would argue that we can employ servants. this is true. however, what shall we do if the servant leaves us and all things are left to ourselves? we just cannot leave our clothes as they are and let worms and ants eat them up. and what can we do it we go and study in a foreign country where servants are out our means to employ? we must work for ourselves. why not start to learn to do housework now or else it will be too late? everyone should learn to do housework. what do you think about my idea, boys and girls?
网络是一种很好的信息交流工具,人类有了它,就能随时随地地获得信息.因此,就有越来越多的网络游戏出现。有部分电脑游戏是以暴力或是其他不良信息作为主题的,当学生玩这种游戏时,就会被灌输这样的想法。
现在网上有许多骗人的.东西,已有不少人上当受骗了,我觉得,我们应该有一颗警惕心,防止一些坏人的犯罪行为。
我认为,上网最主要的目的应该是查找资料,而不是一味的玩游戏,沉迷游戏,这是不好的。万一沉迷于玩游戏,就会影响许多方面的问题。例如学业、与别人沟通等等。所以我们应该坚决反对沉迷游戏。
有一次,我在电视上看到一个男孩,因为沉迷网络游戏,天天都不回家,在网吧通宵上网。家长与学校也已经多次劝阻,可还是屡教不改,最终因过于沉迷游戏,导致精神失常,伤害了别人。
沉迷网络游戏是一种不好的行为。作为学生的我们,应该把精力放在学习上,而不是沉迷与上网玩游戏。我相信,只要我们努力,就一定能将这种不良风气消灭的!
电脑对人体的五大危害:
一是对身体健康的直接影响:电脑显示器伴有辐射与电磁波,长期使用会伤害人们的眼睛,诱发一些眼病,如青光眼等;长期击键会对手指和上肢不利;操作电脑时,体形和全身难得有变化,高速、单一、重复的操作,持久的强迫体位,容易导致肌肉骨骼系统的疾患。计算机操作时所累及的主要部位有腰、颈、肩、肘、腕部等。
二是电脑微波对身体的危害:电脑的低能量的X射线和低频电磁辐射,容易引起人们中枢神经失调。英国一项办公室电磁波研究证实,电脑屏幕发出的低频辐射与磁场,会导致719种病症,包括眼睛痒、颈背痛、短暂失去记忆、暴躁及抑郁等。对女性还易造成生殖机能及胚胎发育异常,出现痛经、经期延长等症状,少数妇女还发生早产或流产,孕妇每周使用20小时以上电脑,其流产发生率增加80%以上,同时,还能导致胎儿畸形。
三是增加精神和心理压力:操作电脑过程中注意力高度集中,眼、手指快速频繁运动,使生理、心理过度重负,从而产生睡眠多梦、神经衰弱、头部酸胀、机体免疫力下降,甚至会诱发一些精神方面的疾病。这种人易丧失自信,内心时常紧张、烦躁、焦虑不安,最终导致身心疲惫。
四是导致网络综合征:长时间无节制地花费大量时间和精力在互联网上持续聊天、浏览,会导致各种行为异常、心理障碍、人格障碍、交感神经功能部分失调,严重者发展成为网络综合征,该病症的典型表现为:情绪低落、兴趣丧失、睡眠障碍、生物钟紊乱、食欲下降和体重减轻、精力不足、精神运动性迟缓和激动、自我评价降低、思维迟缓、不愿意参加社会活动、很少关心他人、饮酒和滥用药物等。
五是电脑散发的气体危害呼吸系统:电脑、激光打印机等设备会释放有害人体健康的臭氧,不仅有毒,而且可造成某些人呼吸困难,对于那些哮喘病和过敏症患者来说,情况就更为严重了。
另外,较长时间呆在臭氧气体浓度较高的地方,还会导致肺部发生病变。
i think students should share some housework with their parents. the reasons are as follows. first, doing some housework can enable the students to have some sense of responsibility. there is a lot of housework in each family. as a member of the family, each one should do his or her share. since a student is a member of the family, undoubtedly, he is of no eception. in the second place, doing some housework can give the student opportunities to get to know his parents better. by doing housework, a student will know how hard it is for his parents to go to work everyday while raising a
family. he will make even greater efforts in his study later on. finally, doing some housework can give the student a chance to do some physicaleercises. since the student has to sit studying most of the time, this is certainly beneficial to his health.in light of the above, i strongly recommend that those who are not in the habit of doing housework start doing some right now. your parents will be pleased and you will learn something from it.
