今天，我收看了《新课堂——同心战“役”特别节目》令我受益匪浅，刻骨铭心。让我对新型冠状病毒有了更进一步的了解和认识，以及学习并掌握了预防措施。
首先，新型冠状病毒是一个大型病毒家族。因为表面的凸起像国王头上的王冠，所以叫冠状病毒。它是目前已知的第七种可以感染人的冠状病毒。感染人群一般出现咳嗽、发烧、头疼、胸闷等症状。
其次，新型冠状病毒肺炎虽然来势汹汹，给我们的生活都蒙上了厚厚的`阴影。但是，作为学生的我们，要把这次的疫情当作是一种学习的机会，去学习前辈这种处变不惊，舍己为人的精神，我们要利用好这个机会，静下来想一想自己的`人生规划，树立正确的人生观，价值观。把我们的祖国建设得更强大，是我们每个人的使命。另外，还要学会如何做好防护措施：第一，尽量不出门，如果必须去公共场所记得佩戴口罩；第二，要经常洗手，第三，不要过度疲劳，这样会降低免疫力。
最后为逆行的勇士们祈福，平安归来！加油中国！

The fox, filled with arrogance, examined the cat from head to feet, and for a long time did not know whether he should give an answer. At last he said, "Oh, you poor beard-licker, you speckled fool, you hungry mouse hunter, what are you thinking? Have you the nerve to ask how I am doing? What do you know? How many tricks do you understand?"
"I understand but one," answered the cat, modestly.
"What kind of a trick is it?" asked the fox.
"When the dogs are chasing me, I can jump into a tree and save myself."
"Is that all?" said the fox. "I am master of a hundred tricks, and in addition to that I have a sackful of cunning. I feel sorry for you. Come with me, and I will teach you how one escapes from the dogs."
Just then a hunter came by with four dogs. The cat jumped nimbly up a tree, and sat down at its top, where the branches and foliage completely hid her.
"Untie your sack, Mr. Fox, untie your sack," the cat shouted to him, but the dogs had already seized him, and were holding him fast.
"Oh, Mr. Fox," shouted the cat. "You and your hundred tricks are left in the lurch. If you been able to climb like I can, you would not have lost your life."
一只猫在森林里遇到一只狐狸，心想：“他又聪明，又丰富，挺受人尊重的。”於是它很友好地和狐狸打招呼：“日安，尊敬的狐狸先生，您好吗?这些日子挺艰难的，您过得怎么样?”
狐狸傲慢地将猫从头到脚地打量了一番，半天拿不定主意是不是该和它说话。最后它说：“哦，你这个倒霉的长着鬍子、满身花纹的傻瓜、饥肠辘辘地追赶老鼠的.傢伙，你会啥?有甚么资格问我过得怎么样?你都学了点甚么本事?”
“我只有一种本领。”猫谦虚地说。
“甚么本领?”狐狸问。
“有人追我的时候，我会爬到树上去藏起来保护自己。”
“就这本事?”狐狸不屑地说，“我掌握了上百种本领，而且还有满口袋计谋。我真觉得你可怜，跟着我吧，我教你怎么从追捕中逃生。”
就在这时，猎人带着四条狗走近了。猫敏捷地窜到一棵树上，在树顶上蹲伏下来，茂密的树叶把它遮挡得严严实实。
“快打开你的计谋口袋，狐狸先生，快打开呀!”猫冲着狐狸喊道。可是猎狗已经将狐狸扑倒咬住了。“哎呀，狐狸先生，”猫喊道，“你的千百种本领就这么给扔掉了!假如你能像我一样爬树就不至於丢了性命了!”

我国从2000年开始，将每年9月命名为“脑健康月”，规定9月16日为“全国脑健康日”。在“脑健康日”来临之际，北京三博脑科医院首席专家于春江教授为我们解读了脑疾病和脑健康的相关知识。
“大脑是由100亿个神经元构成的，全部脑血管连接起来的长度接近17万公里，大脑是人体各个生理活动的最高调节器官，是心理思维活动的中心器官，对人体发挥着整体性的调节作用……”
大脑是一台高精密且每天都在高速运转的“机器”，随着使用年限的累积，它也会出现老化、故障、“死机”甚至彻底“报废”的危机，一旦这些情况出现，人的正常生理机能就会失控，甚至危及生命。
“大脑是人体最特殊、最重要的一个器官，它的健康是不可逆的，一旦出现问题就是灾难性的。”陕西康杰医院李新华教授强调，尽管脑健康至关重要，但人们对它的重视程度还很不够。
发达国家早就认识到脑的重要意义，美国和日本都相继提出过“脑的十年”、“理解脑、保护脑、创造脑”的口号，国际脑研究组织在第四届神经科学大会上，也将21世纪定义为“脑的世纪”。
