北京时间10月16日0时23分，搭载神舟十三号载人飞船的长征二号F遥十三运载火箭，在酒泉卫星发射中心按照预定时间精准点火发射，约582秒后，神舟十三号载人飞船与火箭成功分离，进入预定轨道，顺利将翟志刚、王亚平、叶光富3名航天员送入太空，飞行乘组状态良好，发射取得圆满成功。
宇宙探索无止境，太空奏响中华曲。每一次神舟发射总是激动人心，为祖国自豪;每一次太空探索总是鼓舞人心，为时代点赞。神舟十三号载人飞船发射圆满成功，新“太空出差”三人组美丽启航，我们欢呼。浩瀚苍穹立新功，太空探索写华章，中国精彩！
飞天梦瑰丽，乐章总嘹亮。每一次神舟发射都会给我们奏响诸多“首次”交响乐——载人飞船将采用自主快速交会对接的方式，首次径向停靠空间站;航天员将首次在轨驻留6个月;女航天员将首次进驻中国空间站，航天员王亚平也将会成为中国首位实施出舱活动的女航天员，神舟十三乘组也将包括中国首次出舱的男女航天员;中国人将第一次在太空中过春节;等等。每一个“首次”都是科技探索创新的成果，每一个首次都是中国智慧、中国力量的结晶，正是在这些“首次”中，中国航天事业昂首阔步，中国复兴伟业走向成功。
使命很光荣，任务更厚重。每一次太空探索都是壮美事业的伟大音符，是总结，是升华，是更上层楼的力量凝聚。中国空间站在轨建设分为关键技术验证和建造两个阶段实施，神舟十三号任务是空间站关键技术验证阶段的决胜之战、收官之战，也是空间站在轨建设过程中承前启后的关键之战。通过神舟十三号任务，将更加全面地考核工程各系统执行空间站任务的功能性能，以及系统间的匹配性与协调性。神舟十三号任务结束后，还将组织进行全系统综合评估，满足要求后转入空间站建造阶段，所以说，其任务意义非凡而深远。
探索星辰大海，中国征程壮美。新“太空出差”三人组，组合完美，“老中青”结合，抒写完美中国太空新记录。一曲《东方红》响彻寰宇、“两弹一星”让世界瞩目，“载人航天”挥毫惊鸿之笔。“嫦娥”奔月、“北斗”指路，“天问”问天、“天宫”览胜，“玉兔”探月、“祝融”探火、“羲和”探日……从一人一天到三人半年，美丽传奇，刮目奇迹。九霄逐梦问天，阔步强国征程。上九天揽月，观天上宫阙。这是国家和民族的共同记忆，这是共和国发展壮美诗篇。
浩瀚苍穹立新功，太空探索写华章。中国载人航天精神伟大，“天和”探索之旅美好。航天员王亚平说，只要敢于有梦、勇于追梦，用智慧和汗水打造自己的梦想飞船，就一定能够迎来自己梦想的发射时刻，飞向属于你的浩瀚星空！中国外交部发言人赵立坚说，我们期待除夕守岁时，能够第一时间听到我们的同胞来自太空的祝福。行而不辍，未来可期。神舟十三号任务展现中国为载人航天探索这一人类共同事业作出的新努力、新贡献;中国必然为人类探索宇宙奥秘、和平利用太空、推动构建人类命运共同体作出积极贡献。

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。

自从有了网络，我们的生活质量就渐渐随之改变。
先说通讯：自古以来，我们的通讯就不大方便：原始时期的“叫喊、吼声”，然后是有了文字与语言出现了的“飞鸽传书”，直至后来的电报通信。每一步都是历史性的创新。现在，我们几乎人人都有手机，家家都有电脑。有事打个电话、发个短信，事情就解决了。而这些都与网络有关，没了网络该有多大的不便！
当然，有了网络，工作也快捷了。
首先，办公用的资料不会占地方，没有的再百度，怕忘记再保存在电脑里，实在不行添一个备份；如若客户在较远的地方，还可以视频，不必担忧；想要的东西还可以网购，不怕再怕没有，不必再有担忧。
对于我们这些学生，网络可以辅助：资料、问题都可百度。偶尔关注微博、QQ，空暇时还可娱乐、休闲。
但是网络不是只有“利”，他也有一些弊端。
不少人沉迷网络：公交车上总有几个人低着头在摆弄手机，成了所谓的“低头族”；网吧中不少青年通宵打电玩，导致猝死；学生们过度沉迷网络，而误入歧途；由于网络的诱惑，大部分人导致近视。
虽说学生有着家长在限制，网吧也有国家施行的限制（未成年人），但是这种情况并未有多大缓解，不让我们接触网络也无法实行。现在，网络几乎不能与我们分离……
网络，很现代；但是，现代总会有弊端。
科技，到底是进步还是退步？

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.
