所谓一日之所需，百工斯为备，有前人的努力，发明出各式各样的产品，我们才有便利的生活。现在的科技很发达，每个人几乎人手一支手机，我想，最伟大的发明应该就是网络了！
网络，可以让你跟远方的人取得联系；网络，有助于增加知识、提供生活资讯、广交朋友、排除寂寞、打发时间；网络，人际关系可获得改善。但网络同时有它的好处与坏处。网络，真实姓名、年龄、外表皆可隐藏。有些人会遗弃现实，转于投向虚拟世界，对他们而言，虚拟世界比真实世界更真实。在逃离现实的时候，不知不觉会发展出不当的网络使用，就好像上了瘾一样，欧美国家称这些人为网络狂。
网际网络世界丰富的内涵可使个人从单调的生活中解放出来，让人能依自己独特的想象力发展各自的潜能与兴趣，对一些人而言，当他们的身份与他人不同时，网络的匿名是具有正面意义的，虚拟网络空间可以满足人际交往、归属感、学习、自我尊严、自我实现的需求，也是个人学习、显现个人网络专业、提高成就感最好的场域，属于人类基本需求最高级的自我实现之成就感可在此环境中发挥出来。
网际网络虽然带来许多的便利性，包括人际互动、友谊、支持、归属感、高成就感等，但是却也带来一些负面的效果，包括焦虑、易怒、失落、没有勇气等心理幸福感的丧失，我们必须要认清自己是人的本质，科技始终来自于人性，科技只是一种工具，并非人的全部。我觉得网络是生活中最伟大的发明，只要你正当的使用，它终究会给你带来好处的。

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.
