星期六,老师组织我们去气象塔旅游。在路上,一位女气象员自我介绍说她姓雪,可以叫她小雪姐姐。
到了气象塔,我们先来到一个跟电线杆一样的一个杆前,小雪姐姐讲解说它上面像几把勺子的是用来测风的速度的,在勺子的下面有一个板,这是用来测风向的。接下来,我们来到一个像四个雷达一样的地方,它是用来探测天气的温度、湿度、风向、风速。把一个七百五十克的气球灌满氢气放飞到天空中去,用它来探测气球、天气。小雪姐姐说:“空气里有氮气、氢气、二氧化碳、氧气等。”
小雪姐姐让我们也来当小小天气预报员,我迫不及待地举起手来说:“今天西安四摄氏度小雨转小雪,汉中零下六摄氏度中雪,商洛七摄氏度持大暴雨,陕西气象台播出。”大家连声说我说的好,老师也奖励了我一朵可爱的小红花。
通过这次观测,我知道了气象员是怎么观察天气的,同时,我也当了一天快乐的小小气象员。
每年3月23日,是世界气象日。3月20日这天,新乡市气象站对市民开放。难得有如此机会,我们一家人早就商量着星期日去气象站参观。
我们坐车去气象站。因为路不太熟悉,所以路上问了两三个人才到了气象站。我一下车,直奔风向标。那里已经围了五、六个小学生了,个个满脸好奇,摸摸这儿,看看那儿,还在争辩着什么。风向标以前在电视里我倒是见过,不过见实物这还是第一次。你看这家伙,象个标竿,其貌不扬的,可谁知它竟会准确测出风向风级。过了一会儿,气象站里一个头发黑里有白的伯伯,带我们进入观测站进行参观。
我们先来到一个百叶箱旁边,伯伯打开百叶箱,里面有四个测量管。虽说看起来和温度计差不多,可实际差远了。这些管子是测量一天中的最高温度和最低温度的。
我们来到第二个百叶箱旁,这里放的是自动测量仪,而且能画线,能画出一天中不同时间的温度和湿度的变化曲线。
第三个百叶箱,我们一看,是一个像一根短棍似的东西。伯伯一讲,我才明白,这是目前世界上最先进的天气监控装置 。它把每一分钟的数据及时传进室内的电脑,由电脑加以统计,结合人脑分析,就能准确地给出天气情况。
其他还有测降水量的、测地表和地下不同深度(直到地下3。6米)的温度的,还有测雾凇、测蒸发量的仪器,等等。伯伯说,准确预报这些天气情况,能为农业生产和生活提供许多方便。
这次参观,真让我增长了不少见识呀!
On the afternoon of October 28, the weather was particularly sunny. The day I had been looking forward to for two weeks finally came. Today, we are going to the emergency rescue training base of the Municipal Red Cross Society to learn first aid knowledge and skills.
We took a bus to our destination. First of all, the volunteers of the Municipal Red Cross Society explained to us the origin, functions and components of the Red Cross movement.
From his introduction, I know that may 8 is the World Red Cross Day every year. The bright red red cross represents the spirit of humanity, fraternity and dedication. Then, we started the practical operation. The first one was cardiopulmonary resuscitation. Volunteers introduced the operation process of cardiopulmonary resuscitation and simulated first aid.
Secondly, volunteers also teach us four skills of trauma rescue: hemostasis, dressing, fixation and handling. When learning hemostatic bandage, volunteers showed us triangular towel head bandage, stirring rod bandage, etc. Finally, we carry out practical operation.
Under the careful guidance of volunteers, we studied very hard, and everyone mastered these first-aid skills.
Time passed quickly, and the afternoons study soon came to an end, and the students were still not satisfied. Before I took part in this activity, I didnt know what the Red Cross did, and I never wanted to know it. Through this afternoons study, I deeply felt that the Red Cross Society is really great. I want to inherit its spirit and be a loving person. Thank you very much for allowing me to participate in such a meaningful activity!
在中国的首都北京,那漫天弥漫的雾霾,是隔绝了空气间流通的一层保护膜,堪称又一个”世外桃源”。阳光的气息,透不过厚厚的霾,让自己陷进了深深地混沌里,我该怎么道歉,才能回到童年的记忆中,天空是湛蓝的,空气是清新的,阳光是明媚的。我知道你会说,你们太贪婪了。是啊,人的私心像黑洞,多少都填不满,永无止境。首都是什么,是象征,是标志,中华儿女更应该有义务的爱护,保护,呵护。了解国家的第一步,自然而然就想到首都,让世人重新认知北京,我相信,环境的改变,会让中国的面貌焕然一新!
老话说,水是母亲,过去的你是清澈的,是甘甜的。如今,好多好多次,我都想道个歉,他们说你是臭的,是黑的,是有毒的。我想说,难道这不是你们自己糟践的吗?为了利益,为了买卖,竟不惜污染了生命之水,最终还是搬起石头砸自己的脚。水能载舟,亦能覆舟,能给我们带来欢乐,也能带来灾难。我知道,你已经忍无可忍了,不知道你是不是后悔了,后悔给了我们生命。如果时光能够倒流,我希望,不要再犯同样的错误,借前车之鉴,给自己,也给母亲一个舒适的时代。
我曾看过一张老照片,上面是一片林海,浩茫连绵。曾一度是鸟类栖息的欢乐丛林。好景不长,人类为了生存,侵占了这片领域,开始了砍伐交易。听说砍伐是从五十年代开始的,大卡车一辆接着一辆,每天不停的往外运,有时,一整天,整个山谷里都回荡着汽车的发动机声。此后,鸟儿再也不光顾那片丛林上的天空。空气中夹杂着一些难闻的\'汽油味,似乎还隐隐约约的嗅到一股树根腐烂的味道。砍伐一直持续到九十年代中,如今算来,那些树的年龄比我爷爷的爷爷年龄还要大许多,现在就仅剩下一小片了。我知道,再不停止这些砍伐活动,可能你们这一小片也留不住了。迷茫的人类,看看自己做了些什么,这不是活生生的剥夺了寿命的权利嘛,住手吧,不要再出现荒山了,也不要让心慌下去了。
做为发展中国家,经济发展的活跃度还算低靡,要想跻身前列,必须让科技实力发展起来,人们苦思冥想,在一片广袤无垠的大草原上发现了新事物。随后的行为举止,可想而知,他们肆无忌惮的挖空了草原的下面,原本光鲜亮丽的草原变成了坑坑洼洼的样子,再一次的让动物们失去了沃土,土壤丧失了原有的生机。每到雨季,隆隆的雷声和大地的沦陷声交杂一起,在草原上此起彼伏,像是在诉说身上千疮百孔的伤口,那难以启齿的疼痛。我不知道你还能不能养育我们,不知道你还愿不愿意养育我们,那些难以抹平的伤口,该怎样来填补呢。
世界道歉日,先从大自然的道歉开始,以点带面,向山川河流道歉,向阳光大地道歉,向天空草原道歉,让这种态度蔚然成风。回望过去,那些伤痕累累的足迹,是我们犯下的滔天罪行,现在的我们只是被定了“有期徒刑”,等到哪天被判为“死刑”时,就追悔莫及了。到此,请心存歉意,用实际行动来证明我们的决心,原谅我们先前的所作所为,接受我们的道歉,让我们好好的替你清理、洗涤。
This is my first time to participate in the practice activity of Haidu little reporter. When my mother told me that the activity content was to learn first aid knowledge, I began to look forward to it.
When I came to the auditorium, I saw the theme of the activity at a glance: everyone learns first aid and first aid is for everyone. After a while, the activity began, \"lets invite Dr. Zhang from the emergency department of Jinjiang hospital!\" as soon as the voice fell, a male doctor wearing white divination walked on the stage and explained in detail \"what should you do if someone suddenly faints in front of you?\"
Dr. Zhang told us that cardiopulmonary resuscitation should first observe the environment and confirm the surrounding safety before rescue. I pricked up my little ears and listened attentively for fear of missing any link. Dr. Zhangs explanation was not only professional but also interesting. I firmly remember every step of cardiopulmonary resuscitation he said.
After listening to the explanation, its natural to experience it. All the students are eager to try and hold their hands high. I especially want to try, but its a pity that only two students are lucky to complete the practice.
Todays activity is very meaningful. I not only learned the first aid knowledge that can \"save lives\", but also gained a lot of laughter. In this happy atmosphere of \"learning by playing, learning by playing\", I absorbed more knowledge. I think if I meet someone who suddenly faints in the future, I will \"save\" them with the first aid knowledge I learned today.
