随着科技的发展,电脑逐渐步入了现代家庭,为人们的生活带来了便利,但同时也制造了许多不必要的麻烦,令我们既喜爱又惧怕。
网络,是知识的海洋。有一次,要上公开课,老师让我们搜集资料,正愁没法子的我忽然看到了电脑,心想:我何不利用网络来帮我搜索所要的资料呢?就这样,我迅速打开电脑,找到了资料,并打印了出来,心满意足的我不由赞叹道:“这网络可真神奇!”网络不仅能通过查阅资料学到很多的知识,还可以阅览书籍,听音乐……令人数不胜数,瞠目结舌。
网络,开阔了我们的视野,是我们的良师益友……同时,它也是一个隐形***手,不停地制造“事件”。就拿表哥来说吧,他的成绩在班上本不算很差,但自从解除了电脑,他就像着了魔似的,学习成绩一落千丈,阿姨对此都是甚是操心,打骂劝都试过了,但还是抵挡不住电脑的诱惑,沉迷于网络。
当今社会,有许多儿童被网络束缚了心,掉进了网络的“陷阱”,无法自拔,这也是我们的父母最担心的一面。虽说网络是一把双刃剑,但我认为它的其利大于其弊,只要我们合理安排时间,正确地实用网络,那它将会为我们服务,成为一名无声的老师。要是我们稍不留神,跌进网络早已布置好的全套中,到时候我们就会永远被网络所奴役,无法恢复原本真实的自己。同学们,行动起来吧!让我们健康上网,快乐学习!为自己的未来着想,为父母着想……远离不良网站,倡导绿色健康网!
今天凌晨,长征二号F遥十三运载火箭在酒泉运载着神舟十三号飞船点火升空,搭载着3名航天员如利箭般刺破苍穹,飞向太空。这是我国载人航天工程的又一次重大成功,是我国空间站建设的“关键之战”,青岛科技一如既往地提供了护航技术支撑。
早在此次任务发射前期,中国电科22所的信息保障团队就已全面进入工作状态。一方面,这支团队全力为此次任务提供了空间电波环境态势和异常事件预报预警信息,为发射窗口的确定提供了技术支持;另一方面,团队还为任务系统提供了高精度电波环境效应数据,保障航天测控、卫星通信和空间目标监视雷达等系统的可靠运行。由中国电科22所研发的便携式定向仪、陆用型信标机、海用型信标机、航天员通话电台等设备齐“上阵”,组成了一张近、中、远程搭配,海、陆、空协同的立体化搜索救生网络。这套多次为我国航天任务发射提供保障的“明星装备”再次为神舟十三号的顺利出征提供了坚强护航。
“复杂网络与可视化研究所航天可视化团队研制的深空探测实时三维可视化技术,在本次飞行任务中再次接受了实战任务考验。”团队博士郭阳告诉记者,飞船在空间飞行状态是难以被直接观测到的,该技术可将飞船飞行过程中产生的海量数据在0.1秒内进行“实时翻译”,驱动控制中心屏幕上的飞船模型调整位置与姿态,让地面控制人员可以在第一时间看到飞船“实况”。“这项技术就像飞船的‘眼睛’,让它保持更好的姿态运行。”郭阳表示,航天可视化团队为神舟十三号载人飞船在此次“太空出差”提供轨道修正、姿态调整以及飞行控制与指挥提供关键技术支持和工程保障,团队研制的深空探测实时三维可视化技术在神舟十三号飞船和天和核心舱进行自主交会对接任务中发挥关键作用,并为神舟十三号飞船在轨飞行保驾护航。
“团队研制的深空探测实时三维可视化技术在执行交会对接任务中,已经助力中国航天事业10余年,已成为北京航天飞行控制中心常态化任务执行系统。”据郭阳介绍,该团队早在2011年萤火一号火星探测器发射任务中就已经作为任务全过程的推演平台,曾先后参与并圆满完成多项国家重大载人航天、探月工程以及深空探测等工程实战任务,主要包括天问一号火星探测,探月工程嫦娥二号、嫦娥三号、嫦娥五号T1飞行试验器、嫦娥四号以及嫦娥五号任务的可视化飞行控制指挥与遥操作操控任务,载人航天工程天宫一号与神舟八号、神舟九号、神舟十号,天宫二号与神舟十一号、天舟一号,空间站天和核心舱与神舟十二号、天舟二号交会对接任务的实时三维可视化飞行控制与指挥任务。
网课,是疫情时美丽的流行;关怀,是生活中永恒的经典。——题记
E-learning is a beautiful epidemic in the epidemic; caring is an eternal classic in life. ——Inscription
疫情的肆虐使今年的.寒假出奇地漫长。为了让我们“停课不停学”,老师们都摇身变成了“主播”或线上“客服”。一时间,网课成了美丽的流行,而老师们隔空的帮助让学生觉得这个寒假不太冷。
This years winter vacation is surprisingly long because of the epidemic. In order to let us \"stop classes and never stop learning\", teachers have become \"anchor\" or \"customer service\" online. For a while, online classes became a beautiful fashion, and the teachers help in the gap made students feel that this winter vacation was not too cold.
网课之初,我们学生大部分还可以管控好自己。可“路遥知马力,日久见人心”,有些同学渐渐显示出了本色,私底下约定时间玩游戏、跟同学聊天,甚至忘记了上网课。可是你们知道吗,老师为了让我们“不停学”,费尽了心血。
At the beginning of online classes, most of our students were able to control themselves. However, some students have gradually shown their true colors. They have privately arranged time to play games, chat with their classmates, and even forget about online classes. But did you know that the teacher made great efforts to keep us going.
就说我们班的黄老师吧,每天傍晚,都要为我们准备第二天的所有学习任务清单。老师要先把视频课看一遍,如果效果不好,又会继续搜寻,一定要寻找到最好的学习资源,争取不给学生留下一丝漏洞和不好的体验。
Lets say that Mr. Huang in our class prepares a list of all the learning tasks for us every evening. The teacher should watch the video lesson first. If the effect is not good, he will continue to search. He must find the best learning resources to avoid leaving any loopholes and bad experience for the students.
接着随时监督学生的作业完成情况,那一份份电子作业发出去,每一次都收到写55份作业图片。是图片啊,你能想象得到,老师在屏幕上认真批改每个同学作业的情景吗?不仅有勾画圈点,还有批语呀。张同学哪个字写错了,李同学这个句子不通顺,王同学的字迹太潦草……老师都会一一批注,还经常出现鼓励性语言,为同学们加油,而且几乎不重复。
Then monitor the completion of the students homework at any time. When the electronic homework is sent out, 55 pictures of the homework are received each time. Its a picture. Can you imagine that the teacher carefully corrects each students homework on the screen? There are not only sketching circles, but also comments. Whats wrong with Zhang? Lis sentence is not smooth. Wangs handwriting is too scrawly Teachers will annotate one by one, and often use encouraging language to cheer students on, and almost no repetition.
那次小朱同学忘提交作业了,老师便马上用短信提醒,收到作业图片后,又马上批改,并督促订正。面对作业质量差、态度不认真的同学,老师还会进行电话家访。老师还会在百忙之中抽时间解答学生的疑问呢!
That time, Zhu forgot to submit his homework. The teacher immediately reminded him with a text message. After receiving the pictures, he immediately corrected them and urged them to correct them. In the face of the students with poor quality and not serious attitude, the teacher will also make a telephone home visit. The teacher will take time out of his busy schedule to answer the students questions!
那一次,我在学习文言文《掩耳盗铃》时遇到了困惑,便发了一条信息咨询老师。知道老师很忙,根本没指望老师马上能回复。可出乎意料,不到一分钟,竟然收到了老师的回复,回复中不仅有文字,还有查证的图片,最后还附上一段让我信心满怀的鼓励性话语:很高兴你能这么积极主动地钻研,老师为你的发现和大胆质疑叫好。以后学习上遇到有分歧的问题,不要迷信权威,只管大胆求证。为你的探究精神点赞!
That time, when I was learning the classical Chinese \"hiding my ears and stealing the bell\", I met with confusion and sent an information consultation to the teacher. Knowing that the teacher is very busy, I didnt expect the teacher to reply immediately. But unexpectedly, I received the teachers reply in less than a minute. There were not only words but also verified pictures in the reply. At the end of the reply, I also attached a piece of encouraging words that made me confident and full of confidence: Im glad that you can study so actively, and the teacher applauds your discovery and bold query. In the future, if you encounter different problems in your study, dont believe in authority, just dare to prove it. Praise your spirit of inquiry!
我不知道这次疫情还有多久才能结束,但网课却给我们的学习增添了新时代的快乐,已成为我成长中遇到的最美丽的流行;老师的付出和大爱,让我们的心通过互联网这根神秘的丝线,紧紧地联系在一起,那无微不至的关怀,已成为我生活中永恒的经典。
I dont know how long it will take for the epidemic to end, but online classes have added a new era of happiness to our learning, which has become the most beautiful fashion I have ever met in my growth. The teachers efforts and love have made our hearts closely linked through the mysterious thread of the Internet. That meticulous care has become an eternal classic in my life.
“飞天梦永不失重,科学梦张力无限。”8年前,“太空教师”王亚平为全国6000多万名学生太空授课时的寄语尚萦绕在耳畔,如今她又一次踏上了太空之旅,将成为中国首位进驻空间站的女航天员,以及中国首位出舱女航天员。寻声凝望,原本神秘遥远的深邃太空离我们越来越近,一个个美丽的“飞天梦”正成为现实。
16日凌晨,神舟十三号成功发射,此时距神舟十二号载人飞船成功返回不到一月时间。由翟志刚、王亚平、叶光富组成的新“太空出差三人组”搭乘载人飞船奔赴中国空间站。此次任务将实现与核心舱径向交会对接、由救援船转入正式任务船等多个“首次”,还将在神舟十二号任务的基础上开展更多的空间科学实验与技术试验。
“坐地日行八万里,巡天遥看一千河。”2003年,神舟五号飞船搭载杨利伟在酒泉卫星发射中心发射,历时21小时23分钟成功返回地面,首次实现了中华民族的飞天梦。18年来,7次载人飞行,间隔期从以年计算到以月相隔,“出差”的频率更快、衔接更顺畅,准备更从容,展现着我国科技自立自强的能力;太空之旅从“一日游”到“季度游”,再到此次半年的“深度游”,“太空出差”的时间更长,步伐迈得更大更远更坚定,彰显着大国自信的豪情。
如今,上网已经成为了人们十分热衷的一个话题。网上,有很多的东西,国内国外的都有。娱乐、新闻、电视剧、电影等等。所以,大部分的人都喜欢上网,特别是年轻人和学生。但是,有大部分的家长,都反对孩子单独上网。
上网的利。网上包含着许多我们在日常的学习中涉及不到的许多知识,我们可以利用闲暇时间来查一查我们想了解或是还没有想明白的一些东西,比如,我想了解秦文君的背景,我就可以百度秦文君,获取我们想要的结果。我们还可以查看一些文学作品,读一读小说,这样,既方便又快。也不用在偌大的读书馆里面如“大海捞针”般地去寻找我们想要的书籍。最后,还有游戏,现在许多家长都反对孩子玩游戏,并认为所有的游戏对孩子只有坏处。其实,这样的想法是错误的,玩一些小游戏不仅对孩子没有坏处,还可以锻炼孩子的审美观、反应能力等等。
但是,现在的不法分子却利用网络来干坏事。在网站里面放病毒,毒害用户的电脑,甚至控制他们的电脑。最可恨的是,制造一些黄色软件,毒害人们的心灵,毒害社会的风气。其次,就是电脑的辐射,还有就是一些学生不务正业,沉迷于网络游戏中,导致学习成绩下降。这三种现象,也就是家长反对孩子花太多时间在上网上的\'原因。
我觉得,上网可以上,但是我们要在适当的时间,适当的地点上网,有必要的话,将上网的内容告诉父母,以免造成不必要的误会。把握好查询的范围,上网才能真正对我们有益哦!
信息技术的发明给生活带来了无与伦比的便利,因此计算机网络和信息系统已经成为人们日常生活中不可缺少的重要工具。
计算机网络世界真的很方便。你不必去其他地方,在家里喝茶、聊天和听音乐。你可以跟随现代人的脚步,随着现代科技的发展成为一名快速的互联网技术专家。计算机的网络世界,它的快速性和多样性,确实让人们震惊。它可以用来搜索信息,网上购物,发送电子邮件,写作和谈论…等等。我说不够。我只能说我对它非常敬畏和钦佩,我也充满了兴奋和好奇,因为它是如此多才多艺,以至于三个头和六只胳膊不足以描述它的威力!当我们享受现代网络技术时,我们真的被古人深深地感动了。虽然互联网给我们带来了极大的便利,但与此同时,各种欺诈和信息安全威胁也在不断涌现。使用即时通讯,坐在家里,一天24小时盯着电脑,造成严重的眼睛损伤;虽然“QQ”和“微信”缩短了人与人之间的距离,但这种感情的依恋却远未达到。
我们生活在一个计算机世界。我们只知道电脑游戏和网上聊天,但我们不知道如何采取预防措施和面对面的人际礼仪。导致电脑中毒和异常人格发展的“宅男”确实弊大于利。面对如此奇怪的社会现象,我们怎么能不警觉呢?计算机信息技术的发明使我们和世界每一个角落的人们真正“天堂仍然是我们的邻居”。
虽然网络世界有其可怕的一面,但只要我们一步一步,始终面对深渊,不落入坏人设计的陷阱,网络世界就能让我们一起快乐自由地漫游。

新世纪呼唤绿色的网络生活。毫不夸张地说,网络就像一只蜘蛛,它结出的“网”覆盖了全人类。网络虽可以改变我们生活,但不能代替我们的生活全部。合理的绿色上网,才能达到它的真正效果。
网络是一把双刃剑。要根据实际情况,正确使用网络,做到绿色上网。作为新一代的小学生,绿色上网主要指控制上网时间和正确选择上网内容。怎样做到绿色上网,我想老师、家长的正确引导和监督可以帮助我们。然而,更重要的是靠我们自己。一方面我们要培养自我约束力,另一方面培养自我控制力,不能玩的游戏、不能看的内容,坚决不打开,不下载。说实话,谁不喜欢上网玩游戏、看视频寻找乐趣?正是这种乐趣让许多学生深陷其中而不能自拔。
我的一个表哥,十几岁时,就把无数游戏玩了通关。当时我们几个小兄弟都很佩服他。可后来他完全上瘾了,上初中时竟然偷偷地从她妈妈包里拿钱去给游戏卡充值,表面上他玩得很痛快,可学习被耽误了,考不上大学是预料之中的了。后来他去部队当兵,到了部队,他如梦初醒,下决心努力学习争取考军校,虽然他每天学到深夜两三点钟,可因为文化基础太差,最终还是没考上军校,悔恨当初不该沉迷网络。
像这样的例子,在我们身边是数不胜数。我们要引以为戒,不能让自己美好的时光与游戏为伴。绿色上网,正确使用好网络,让它为我们生活、学习带来轻松、快乐的同时,更成为我们学习、生活的好帮手。
