有一回上课时,男同学郑宇星拍了拍前座的椅背,等前座的吴家豪回过头来,他又站起来,对吴家豪悄悄的耳语了几句,吴家豪立刻转过身去,目不转睛地盯着老师,身体坐得非常端正。这一情景正巧被时时老师敏捷地“捕捉”到了,他温和地对郑宇星问到:“你上课和同学讲话,在讲什么呀?”郑宇星手足无措地回答首:“我、我告诉吴家豪:‘上课不要做自己的事,眼睛盯紧黑板……’”“你这样,很好,但是,如果人人都这样,课堂上不就一片乱哄哄的吗?我们尽量用手势来表达,好吗?”时老师友好的'建议道。
我认为,这句简短的口头禅,不仅代表着时老师的看事全面,明察秋毫,而且更重要的是,它意味着时老师对同学们的平起平坐和尊重。
古时候,人们总是想把一些探测器送上太空。不过,功能单一,并不能完成人们对太空的探索。于是,人们开始想办法:怎么让人上天!我们这次采用的是“长征二号火箭”和“神舟十二号飞船”组成。
上一次太空,要花费很多钱,如果只上去三四个小时又觉得不划算,我们想建一个像酒店一样能让宇航员住的地方,就是空间站。
按照计划,空间站一共由五个部分组成:第一个是“载人飞船”,主要接送宇航员;第二个是“问天实验舱”,是用来做一些地球上完成不了的实验;第三个是“梦天实验舱”,和“问天实验舱”差不多,也是用来做实验的;第四个是“天和核心舱”,我们国家的宇航员就是住在这里面;第五个就是“货运飞船”,主要是负责运送各种物资的。不过,这个计划还没完全完成,现在的空间站只有两个部分:“天和核心舱”和“运货飞船”。据说,在2022年的时候,空间站就能补齐了。
传说有个广寒宫,是在月球上的,而咱们的空间站是飘在太空里的。太阳每天都会朝地球放射“能量”,不过我们在地球上晒太阳时,太阳离我们较远,危险不大。宇航员在太空中晒多了太阳可能会得癌症,所以规定空间站不能高于地球1000千米。科学家们在考虑到经费、实验效果等各种因素,最终,把空间站定在了离地球400千米的太空。
在地球上,你扔的东西都会掉到地上,这就是牛顿提出的“万有引力”。如果,我们站在平地上扔东西,就会下落;那要是我们把飞船以非常快的速度“丢”上去,它下落的程度,就和地球的弧度保持一致,那飞船就可以沿着地球飞了。空间站飞得很快,一个半小时就能转地球一圈。
从古至今,人来想要在地球上看整片天那是不行的。如果从空间站上就看的一清二楚,因为站得高,看得远。
太空环境下能做一些地球上做不了的实验,比如说找出一些比手机芯片更紧密的芯片,或是一些环境下能变色的东西。
这次的宇航员上太空主要有几个小目标:住上三个月左右;调试一下各种设备;做一些不可思议的实验;出舱看太空和空间站的全貌。
中国的空间站,让我们能探索太空更多的奥秘。
振奋人心的那一刻,航天员翟志刚、王亚平、叶光富先后进入天和核心舱,后续将按计划开展相关工作。
我国高科技发展突飞猛进,神舟七号发射成功,5G互联网研究与产业化获得重大突破,我国"首条国际一流水平的高速铁路在京津两大城市间开通,"首个中国人基因组序列研究成果发表,"北京正负电子对撞机重大改造工程建设任务圆满完成,"曙光5000A跻身世界超级计算机前十。
蛟龙深潜,嫦娥探月。我国科技实力不断进步。重大科技成果持续涌现,科技创新日趋活跃,为经济高质量发展注入了新的活力。
千年梦想,今朝实现。去年7月23日,天问一号在文昌航天发射场由长征五号遥四运载火箭发射升空,成功进入预定轨道。天问一号于2021年2月到达火星,实施火星捕获。2021年5月择机实施降轨,着陆巡视器与环绕器分离,软着陆火星表面,火星车驶离着陆平台,开展巡视探测等工作,对火星的表面形貌、土壤特性、物质成分、水冰、大气、电离层、磁场等科学探测,实现中国在深空探测领域的技术跨越[5]。深空探测将推动空间科学、空间技术、空间应用全面发展,为服务国家发展大局和增进人类福祉作出更大贡献。
截至2021年2月3日,“天问一号”探测器总飞行里程已超过4.5亿公里,距地球约1.7亿公里。
我们正站在“两个一百年”的历史交汇点,全面建设社会主义现代化国家新征程即将开启。征途漫漫,惟有奋斗。我们通过奋斗,披荆斩棘,走过了万水千山。我们还要继续奋斗,勇往直前,创造更加灿烂的辉煌!
神舟十三号的航天员按计划将在轨驻留6个月,在这6个月时间,主要工作是要进一步验证空间站建造和运营的关键技术。具体来讲,就是要和核心舱、天舟二号、天舟三号一起配合进一步验证。
科技强,则国强。自信之路成功,为中国航天点赞。神舟十三号载人飞船发射取得圆满成功,又一次让我们感受到祖国的强大。
航天科技一直是任何国家都必须重视的一个新兴领域,她对我们探索太空以及探索未知领域有着很重要的作用。在如今这个社会上,制空权已经变得非常的普及了,那么还更深层次的就是宇宙太空的权利。比如说美国这个强大的国家,他们率先登陆月球,然后他就联合其他的国家在月球上面划分区域,说谁占领谁就在将来拥有采矿的权利,所以我们的航天技术也不能落后,否则的话在未来的100年内我们将会逐步的落后,所以航天技术以及航天的爱好将是我们新一代颜最重要的一个方向。
第一次接触航天方面的知识是在幼儿园大班。那一天,老师把一张报纸贴到了墙上,那上面有一艘火箭——其实是神舟六号,还有两个人——其实是费俊龙和聂海胜。听到老师绘声绘色地讲解,我弄明白了个大概,心里觉得自豪。突然,我发现——居然没有一名女性。当时我就想:要是我能当中国的第一名女宇航员,该有多好呀!从那时开始,我便怀揣着这样一份梦想,上了小学。我曾经很自豪地跟班上的.一位同学说,我将来会成为中国的第一位女宇航员,他听了,流露出羡慕的眼神。那时的我自豪极了,觉得当一名宇航员太简单了!三年级,我逐渐了解了一些有关航天方面的知识,这才知道,当一名航天员不是那么简单的,不仅要有学问,要有好的身体,也要有好的心理素质——其实当时我并不明白到底什么是心理素质,只是模糊地觉得是身体好的一部份罢了。
虽然我知道我想成为一名航天航空员已经不太现实了,但是我可以在地下为他们工作,比如说地勤服务以及研究。我们可以在地上研究一些更加安全更加高效的航天飞船或者航天器材,也可以在地下的指挥中心,中间空宇航员的一局动,看看他们的生命体征以及各类的信息安全技术等。所以说,为了我能够实现这个梦想,我现在不断地学习,不断地去参加一些科技展。为的了就是能够更多的了解这方面的知识,为我将来的梦想做铺垫。
奋斗是圆梦的翅膀。一代代航天人在航天“试验田”中勤恳耕耘,心有天地经纬、脚向浩瀚天宇,在一穷二白的基础上艰苦奋斗,在反复试验求索中砥砺前行,在精益求精攻关下追求卓越,敢闯难关、勇开新路。一个个航天员在严格系统全面的训练中学经验、强本领,飞天遨游、出舱行走需要扎实的功底,需要他们具备过硬的心理素质和强健的体魄,寒来暑往的刻苦训练让他们拥有超强的意志力与自信心。为了伟大的航天事业,航天工作者与航天员,将艰辛与曲折作为事业发展的“阶梯”,以志气锻造骨气,以骨气厚积底气,在接续奋斗中实现航天事业更高水平的创新与突破。
从“神一”的发射成功到“神五”“神六”“神七”的宇宙之行……中国的载人航天事业成果丰硕。在“追梦”的道路上,每一次都是全新的征途,每一次都是前所未有的挑战,当然,前所未有的挑战难度也造就了前所未有的高度。鲁迅先生曾说:“其实地上本没有路,走的人多了,也便成了路”,路是由双脚踏出来的,是一步一个脚印开拓出来的。从1956年中国航天事业发展至今,自力更生、自主创新是发展中一以贯之的坚持,是推动航天事业发展壮大的核心竞争力。走前人没走过的路自然少不了弯路,闯前人没闯过的关也必然少不了挫折,成为先驱,方能成为先锋,唯有敢闯,才能闯出新天地,抢占“新高地”。
伟大事业孕育着伟大精神。回望航天事业发展史,无论是“东方红一号”的成功发射,还是神舟系列载人航天工程的重大成就;无论是北斗卫星导航系统的全面建成,还是“嫦娥”奔月与“天问”探火,从大胆设想到成功实践,无不彰显着中国与时俱进的航天实力。中国的航天事业从艰难起步到艰辛跋涉再到取得辉煌业绩,在浩瀚太空中留下的是中国身影、中国足迹,在航天事业的发展道路上留下的是中国精神、中国力量。这种精神与力量必将引领着14亿中华儿女万众一心齐奋斗,激荡起磅礴伟力,奋进新征程,逐梦新时代。
现在疫情当前,为了学生安全,不集聚在一起,我们不能到学校上课,历史上放得最长的一次寒假。为了我们学习,老师在网上直播辅导我们学习。
At present, for the sake of the safety of students, we cant go to school without gathering together. Its the longest winter vacation in history. For our study, the teacher tutored us live online.
为了这次疫情,全国各省各地展开“停课不停学”老师直播上课行动,许多教育机构推出各种学习软件。名师在线免费教学,帮助学生学习,在线辅导。
In order to deal with the epidemic, all provinces and regions across the country launched a live action of "no suspension of classes" for teachers, and many educational institutions launched various learning software. Famous teachers online free teaching, help students learn, online tutoring.
因为上网课直播,各省老师出现了不同的争论。湖南哪吒“对多数学生说,网课的授课效果根本得不到保证,这种形式主义何必存在?”我觉得湖南老师说得不错,上网课,有一部分爱学习的学生能坚持上网课,但是有一部分不自律的同学开着直播就该干嘛干嘛去。所以说上网课不一定得到学习效果。
Because of the live broadcast of online classes, teachers in various provinces have different arguments. Hunan Nezha said to most students that the teaching effect of online courses is not guaranteed at all. Why does this formalism exist I think Hunan teachers are right. In the online class, some students who love learning can insist on the online class, but some students who are not self disciplined can do what they should do when they open the live broadcast. So online classes dont necessarily get learning results.
我个人是觉得上网课没什么学习效果,上网课,老师在线直播辅导各同学,但是人数多,老师又不能每一个人都顾及得到,每个人的问题不一样,只能挑重点讲。一个人在房间里学习,没有在学校教室里学习氛围好。作息时间混乱,晚上熬夜,晚睡觉,预定多个闹钟。早上起来打完卡接着睡。上网课老师不能面对面教导,许多同学都是敷衍了事。老师与同学之间缺乏互动,对于学习好求者可能受益匪浅,但是对于厌倦学习者,学习上没有一点效果,需要老师面对面教导,当面监督学习情况。
Personally, I dont think the online class has any learning effect. The online class and the teachers live online tutoring for each student have a large number of students, but the teacher cant take everyone into consideration. Everyones problems are different, so we can only focus on them. A person in the room to study, not in the school classroom learning atmosphere. The schedule is chaotic. Stay up late, go to bed late, and reserve multiple alarm clocks. Get up in the morning, punch in and go to sleep. Teachers cant teach online lessons face to face, many students are perfunctory. The lack of interaction between teachers and students may benefit those who are good at learning, but for those who are tired of learning, there is no effect in learning. Teachers need to teach face-to-face and supervise learning face to face.
上网课对贫困家庭来说,不方便,有可能老是断网,要是家庭人口多的家庭,孩子都在上网课有可能网络卡。住在农村里的有一些没有信号不好的同学来说也麻烦,不能好好上网课。对上小学的同学们都是没有手机的,父母要出去工作,根本起不到学习作用。
Internet class is inconvenient for poor families. It is possible to always disconnect from the Internet. If there is a family with a large population, it is possible for children to use Internet cards in Internet class. Living in the countryside, some students who dont have a good signal are also in trouble. They cant have a good online class. There is no cell phone for the students in primary school. If parents want to go out to work, they cant learn at all.
学生的专注不在直播上,面对着QQ、微信、游戏、电视的诱惑,有很多学生难以拒绝诱惑,没有吧精力放在上网课上。老师也不知道学生在干什么,人数过多,有的学生一边手机上网课,一边睡觉。或者手机上网课,而学生却在看电视。手机电脑电视对眼睛视力有一定影响,对眼睛不好。
Students focus is not on live broadcast. Facing the temptation of QQ, wechat, games and TV, many students are hard to resist the temptation and have no energy to focus on online classes. Teachers also dont know what students are doing. There are too many students, some of whom are sleeping while taking lessons on the Internet. Or mobile Internet class, while students are watching TV. The mobile phone computer TV has certain influence on the eyesight, but it is not good for the eyes.
所以我觉得,上网课不一定取得到老师授课学习效果,有一些学生未能适应网上学习。学习情况未能得到提升。但是在这个特殊时期,我们现在只能在网上学习了,无论如何,还是希望各位同学们认真上网课,能学一点是一点了。希望学校开学通知早一点来,开始怀念在教室里面学习的日子了。
So I dont think that online classes can achieve the effect of teaching and learning by teachers, and some students cant adapt to online learning. Learning has not been improved. But in this special period, we can only learn online now. In any case, I hope that all the students will take online classes seriously and learn a little bit. I hope that the school notice will come earlier and start to miss the days of studying in the classroom.
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.
