关于网络知识的英文作文【一】
那么体育的功能是什么呢？还不如学好语数外，知识最实在。肥胖一族说，运动可以减肥；心血管疾病患者说，运动不利于身体健康；缺乏运动能力的人说，你跑来跳去，太不安分……这种对运动有偏见的人各执一端，众说纷纭。其实体育运动中蕴含无穷的知识，只有去挖掘，你才会明白其中的奥妙，这正如地下的宝藏，只有挖掘它，才能发现其价值，否则，它就会沉睡大地，鲜为人知。
生命在于运动。它能让你容光焕发，延年益寿。有句长寿秘诀：“饭前一杯酒，饭后百步走，活到九十九。”酒能促进血液循环，增强分子细胞的活力；跑步行走让名骨骼关节得到锻炼，达到强身健体的作用。运动是高山之巅的晨曦，照亮了残弱的身体，让弱者重新振作，让强者更加健康，正所谓流水不腐， 户枢不蠹。
体育是美丽的使者，塑了人体的匀称 与协调。体操运动员那优美的动作，矫健的体态， 柔美的曲线，使人变得健康美丽。三军仪仗队那威武而有节奏的步伐，整齐中含有刚毅，响亮中蕴藏着坚强，大有排山倒海之势，雷霆万钧之力，给人以震撼，给人以壮美。
体育是正义的使者，体现了生活中我们追求的的公平合理。速度用一分一秒支计算，高度用一分一厘去衡量 。差一分你不能夺冠，少一秒你拿不到金牌。运动健将要想取得成功，不能靠投机取巧，不能弄虚作假，不能请客送礼，不能暗箱操作，而只能靠本领与意志的完美结合。如果谁服了兴奋剂，玩弄诡计达到了欺骗同伴的目的，有朝一日，阴谋被揭露，必将名声扫地，遭世人唾弃，因此，正义不容践踏。运动神圣不可侵犯。
体育是一种乐趣。你一旦走上运动场，一切烦恼会抛向九霄云外，内心充满欢乐，血液流动加剧，思路开阔，条理清晰，潜能充分发挥。它使忧伤的人心情豁然开朗，让愉快的人笑声更加响亮，胸怀更宽广，意志更坚强，宠辱皆能忘。
体育是培养人的.沃土。可以增强民族素质，矫正畸形的躯体，防病于未然，使人积极向上，使人懂得礼仪，懂得新生懂得竞争，懂得规则，懂得奋斗，拼搏的内涵。
体育是和平的象征，是友谊的使者。在各民族中架起了一道平等的桥梁，使世界各族人民互相学习，公平竞争，切磋技艺，共同进步。2008年北京奥运会召开在即，我们要通过运动会把和平的种子撒向五湖四海，让友谊之树常青，愿世界的明天更美好。
运动中有无穷无尽的知识，让我们携起手来，在运动中健身，在运动中感悟生命的价值，在运动中去体味知识的真谛，正所谓处处留心皆学问。

关于网络知识的英文作文【三】
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。

On the afternoon of October 28, the weather was particularly sunny. The day I had been looking forward to for two weeks finally came. Today, we are going to the emergency rescue training base of the Municipal Red Cross Society to learn first aid knowledge and skills.
We took a bus to our destination. First of all, the volunteers of the Municipal Red Cross Society explained to us the origin, functions and components of the Red Cross movement.
From his introduction, I know that may 8 is the World Red Cross Day every year. The bright red red cross represents the spirit of humanity, fraternity and dedication. Then, we started the practical operation. The first one was cardiopulmonary resuscitation. Volunteers introduced the operation process of cardiopulmonary resuscitation and simulated first aid.
Secondly, volunteers also teach us four skills of trauma rescue: hemostasis, dressing, fixation and handling. When learning hemostatic bandage, volunteers showed us triangular towel head bandage, stirring rod bandage, etc. Finally, we carry out practical operation.
Under the careful guidance of volunteers, we studied very hard, and everyone mastered these first-aid skills.
Time passed quickly, and the afternoons study soon came to an end, and the students were still not satisfied. Before I took part in this activity, I didnt know what the Red Cross did, and I never wanted to know it. Through this afternoons study, I deeply felt that the Red Cross Society is really great. I want to inherit its spirit and be a loving person. Thank you very much for allowing me to participate in such a meaningful activity!
