一篇关于网课的作文四百字【一】
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！

网络如同一个浩荡宽广的海洋，在这个海洋里，有善有恶，关键的看你自己如何对待。下面请听我诉说网络对我自己的利与弊。
网络的利
上网，可以开阔我们的视野，增长我们的见识，使我们的生活更加丰富多彩，也为我们提供了一个展示自身能力的大舞台。上网可以万事不出门，在家上网看新闻。上网看新闻，可以及时了解国家大事，了解国际形势，了解祖国日新月异的发展变化。上网浏览节目可以了解许多名人的业绩及其成功之路，受到激励，树立远大理想。上网还可以帮助我们学习，让我们了解作者的写作背景，学习不会的英语音标、搜索资料来帮助我们更好更快地掌握今天学习的内容。上网还可以购物，喜欢哪件买哪件，既不用出门又省钱，又方便，何乐而不为呢？
网络的弊
上网，可以影响我们的学习，侵害我们的生活，使我们的生活更加忧患多端。上网会影响我们的学习，占去大量的时间，影响作业的完成，使我们的学习成绩下降。多上网会对眼睛有害，使到我们的视力下降必然会影响我们的学习和生活。上网中浏览的很多节目会有很多的凶***、暴力场面，有一些坏人作案的情节，青少年爱模仿，容易学坏。上网玩游戏，一不小心容易上瘾，会沉迷于网络而无法自拔，就会走上犯罪道路，误入歧途。
这就是上网的利与弊，是我的一些见解。所以说：“网络是一把双刃剑，美丽却拥有着毒性。”
一篇关于网课的作文四百字【三】
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.
