今年的寒假是个不平凡的寒假。由于新型冠状病毒，开学时间延迟。为了保证教学工作的正常进行，学校开展了网络课程。今天是网上教学的第四天，同学们都慢慢适应了这种新颖的教学方法，也没有因为老师的监督而松懈了自己的学习，在课上积极回答老师的问题，认真听讲，课后也按时完成自己的作业。而成为“主播”的老师们轮流完成各门学科的授课，上课很积极，课件准备的很用心，知识点也总结的很到位。我感觉这次网上教学的方法，即能保护同学和老师的安全，又能进一步激发同学们学习的兴趣，从而提高学习的效率。
This years winter vacation is an extraordinary one. Due to the novel coronavirus, the school hours are delayed. In order to ensure the normal progress of teaching, the school launched the network course. Today is the fourth day of online teaching. The students have gradually adapted to this new teaching method, and have not slackened their study due to the supervision of the teacher. They actively answer the teachers questions in class, listen carefully, and finish their homework on time after class. The teachers who become the \"anchor\" take turns to complete the teaching of various subjects. They are very active in class, attentive in courseware preparation and in place in knowledge summary. I feel that this online teaching method can not only protect the safety of students and teachers, but also further stimulate students interest in learning, so as to improve the efficiency of learning.
2020年春节，一场新型冠状病毒引发的肺炎疫情笼罩了中华大地。人们开始足不出户，生活变得压抑起来。在这样的背景下，教育部发布通知“停课不停学”，正式开辟了一种崭新的学习方式，网上授课。
A novel coronavirus epidemic caused by pneumonia in 2020 was enveloped in China. People began to stay indoors and life became oppressive. In this context, the Ministry of Education issued a notice of \"no suspension of classes\", officially opening up a new way of learning, online teaching.
每天在钉钉直播群里上课，我认为这种教学方式变得生动活泼，我的学习兴趣也提升了许多。老师们每节课在直播间里以课件的形式向我们授课，整节课的.知识框架变得清晰明朗了起来，这是十分有利于我们接受并消化东西的。
Every day in nail live group classes, I think this teaching method has become lively, my interest in learning has also increased a lot. Teachers teach each lesson to us in the form of courseware in the live room. The knowledge framework of the whole lesson becomes clear and clear, which is very conducive to our acceptance and digestion.
其次，就是这种方式突破了原有的教学模式。在学校是每一个学科只有一个老师授课，但在网上授课则是许多不同的老师担任我们的任课老师，使我们能充分了解到不同老师的教学风格和特点，进而可以得知自己感兴趣的教学方式。
Secondly, this way has broken through the original teaching mode. In school, there is only one teacher for each subject, but in online teaching, many different teachers are our teachers, so that we can fully understand the teaching styles and characteristics of different teachers, and then we can know the teaching methods we are interested in.
再者，在网上授课时，每个老师一天只需上一节课或两节课，这就为老师们挤出了充足的时间为同学们批改作业及写评语，可以使同学们了解到自己作业的不足和突出的地方，之后就知道我们可以向哪一个方向努力。
Moreover, in online teaching, each teacher only needs to have one or two classes a day, which makes the teachers have enough time to grade and write comments for the students, so that the students can understand the shortcomings and highlights of their own work, and then know which direction we can work in.
总而言之，我们在这足不出户的冬日勃发着学习的兴趣。“冬天来了，春天还会远吗?”我相信，只要我们认真进行网上学习，永远保持着学习的自信，总有一缕阳光，会突破疫情的阴霾，带来温暖的春天。待到春暖花开时，我们再聚校园。
All in all, we are interested in learning in this winter. \"If winter comes, will spring be far behind?\" I believe that as long as we carefully carry out online learning and always maintain our confidence in learning, there will always be a ray of sunshine, which will break through the haze of the epidemic and bring warm spring. When spring comes, we will get together on campus.
网课450个字作文【二】
当前，我们正面临百年未有之大变局、开启了全面建设社会主义现代化国家新征程，机遇与挑战并存，困难与希望同在。一方面，青年干部必须要接好革命事业的“接力棒”，在党的奋斗史中提炼经验、启迪智慧、砥砺奋进，要学做老黄牛，发扬不在乎得失的奉献精神、兢兢业业的责任心，担起新时代开创的重任。另一方面，要以“正青春”的`奋斗姿态和精神状态，努力学习，增长本领，积极作为，答好青春“担当之卷”，在民族复兴这场“接力赛”中，跑出属于青年一代的好成绩。广大科研工作者，应进一步弘扬航天精神，永攀科技高峰，走好新时代的长征路。
发扬“原得此生长报国”的爱国精神。在我国航天事业发展初期，许多功成名就、才华横溢的科学家放弃国外优厚的条件，义无反顾地回到祖国。许多研制工作者甘当无名英雄，隐姓埋名，默默奉献，有的甚至献出了宝贵的生命。他们用热和生命谱写了一部为祖国、为人民鞠躬尽瘁、而后已的动人诗篇。新时代的科研人才要向老一辈科学家学习，坚定科技创新、服务国家的思想，将对事业的追求融入国家的需要，继承前人爱国奉献的传统，以国家和民族需要为研究导向，在科学报国、科技强国的道路上，实现个人、事业、国家的完美融合。
发扬“千磨万击还坚劲”的奋斗精神。在茫茫无际的戈壁荒原，在人烟稀少的深山峡谷，风餐露宿，不辞辛劳，老一辈科研工作者们克服了各种难以想象的艰难险阻。他们运用有限的科研和试验手段，依靠科学，顽强拼搏，发奋图强，锐意创新，突破了一个个技术难关，取得了“两弹一星”事业的伟大胜利。身处这个时代，我们无疑是幸运的，不论是生活环境还是科研条件，都远比老一辈科学家不知要好多少。当代科研工作者以老一辈科学家为榜样，大力弘扬自力更生、艰苦奋斗的精神，在各自的领域脚踏实地、埋头苦干，创造出新的成绩。
发扬“众人拾柴火焰高”的团结精神。在研制“两弹一星”的不凡历程中，来自全国各地区、各部门成千上万的科学技术人员、工程技术人员、后勤保障人员团结协作、群策群力，汇成了向现代科技高峰进军的浩浩荡荡的队伍。他们用自己的辉煌业绩，为中华民族文明创造史增添了光彩夺目的一页。科学研究是一项复杂、艰巨的群体劳动，在科研活动中人与人之间的相互作用直接影响着科研协作和科研计划的完成。广大科研工作者要牢固树立大局意识、协作意识、服务意识，盯紧共同的目标，在充分发挥各自特长的同时，做好相互配合。

尊敬的老师，亲爱的同学们，大家好！今天我要演讲的主题是网络的利与弊。
我们生活在一个科技发达的网络世界。网络是一把双面刃，它可以用来查阅资料，与朋友聊天，但也可以污染一些青少年纯洁的心灵，可以让正走向成功的人跌入无底深渊。玩不良游戏，看不良网站会使青少年们产生心理疾病；每天玩攻击、飞车、枪战等游戏会使青少年们出现道德上的模糊，会打乱你的作息规律也会产生身体上的疾病。比如脑中风，浑身麻痹等，还会使你无法面对现实世界的挫折与失败。
但网络也并不只有黑暗的那一面。它可以使购物、付款更方便。比如：以前大家都要拿着现金出去付款，买好东西后，需要数出足够的金额才能付款，有时还要找钱，非常缓慢。而现在，大家只要拿出手机，在付款应用上输入金额，然后点击确认付款，就可以立即完成付款，不存在找钱的问题。以前如果要买其他国家的物品，只能等到自己去或者朋友寄，需要很长时间，十分不便与缓慢。而现在，大家只要在网上点击自己想要的物品，然后进行远程付款，等几天就能送达。这样就大大提高了效率，十分快捷。
网络可以与远隔千里的亲朋好友进行快捷简便的交流沟通。可以在网上查阅资料，辅助你的学习；可以在网上编程，提高逻辑能力；还可以在网上进行实时问答……
我们都是祖国现在的花朵，未来的栋梁之才，我们要抵制不良网站，合理安排上网时间，让自己的未来充满光明！谢谢大家！
网课450个字作文【四】
神舟十三号载人飞船已于10月16日发射，飞行乘组由翟志刚、王亚平和叶光富3名航天员组成。从9月17日神舟十二号返回地球到神舟十三号发射，时间仅过去短短一个月。按照计划，神舟十三号飞船入轨后，将采用自主快速交会对接模式，对接于天和核心舱径向端口，与天和核心舱及天舟二号、天舟三号货运飞船形成组合体。航天员将进驻核心舱，按照天地同步作息制度进行长达6个月的工作生活。这就意味着，相较于神舟十二号，此次太空挑战的时间更长、难度更大、要求更高，航天员将在太空与我们共同守岁，迎接农历壬寅年的到来。
可上九天揽月，可下五洋捉鳖，谈笑凯歌还。人类对太空的向往和探索从未止步。然而身处太空，浩瀚苍穹看似壮美寥廓，实则挑战着航天员的心理与生理极限，更经历着很多惊心动魄的瞬间。据航天员杨利伟回忆，在执行“神五”任务时，火箭上升阶段意外出现8赫兹左右低频振动，与人体内脏产生长达26秒的共振，此时杨利伟感到了五脏六腑似乎都要碎了一般，令他异常痛苦，可他却咬紧牙关告诫自己“坚持一下，再坚持一下”。事实上，这漫长的26秒共振，只是我国载人航天“首飞”征途上千难万阻、千辛万苦的一个小小缩影，但却画出了中国航天人英勇无畏、舍身为国的“爱国群像图”。
在神舟十二号离开地球的3个月，3名外人眼中光芒四射的中国航天员，均来自普通而朴实的家庭。当他们远离地球、巡游寰宇、辛勤工作时，留在家乡的父老乡亲们在一如既往、年复一年地耕耘劳作。中国航天人的奉献和担当，始于热、恒于信仰、终于爱国，他们把使命和重担铭刻心间、扛在肩上，把荣誉和光环归于祖国、献给民族。
“因热爱而执着，因梦想而坚持”，这是执行神舟十三号飞行任务的航天员王亚平的一番话。每一次针对空间站任务的水下训练，体能消耗都相当于跑一次“全马”，累到手抖得连筷子都拿不稳，但他们累并快乐着。每次离心机训练都要最多承受8个G的过载，脸部会变形、胸部会因受压而呼吸困难，但航天员大队成立20多年来，从未有人按下“暂停按钮”。这种身体可以“过载”，信仰和精神永远“轻装上阵”的状态，诠释的是一种信念、一种意志。革命乐观主义精神、革命英雄主义精神在今天的中国航天人身上穿越时空、力透纸背，焕发出震撼人心、摄人心魄的强大力量。
看似寻常最奇崛，成如容易却艰辛。一个国家、一个民族，在精神上有怎样的海拔，就能攀登怎样的高度。虽然我们不能同神舟十三号的航天员一样把足迹留在浩瀚苍穹，但我们可以在新的长征路上，大力弘扬以爱国主义为核心的民族精神，在祖国建设的各行各业甘做“孺子牛”、勇做“拓荒牛”、常做“老黄牛”，不断以爱国精神、载人航天精神铸魂补钙、淬炼成钢，始终保持“越是艰险越向前”闯劲和“风雨无阻向前进”的韧劲，不断开创新的历史伟业、标注新的精神海拔！

网课450个字作文【六】
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。
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.
