保护环境,从你我身边做起。这是每个人都知道的,我努力在这样做,感觉心里特别踏实。记得有一天,阳光明媚,我和妈妈去公园散步。
我看到一位叔叔在一个角落里随地吐痰,心想:难道这位叔叔不知道要保护环境吗?我真不知道这位叔叔是怎么想的呢!
我加快脚步,上前对那位叔叔说:“叔叔,请你不要随地吐痰。”叔叔没想到我一个小孩会说这么说话。难为情地说:“谢谢你,小朋友,我会努力改正的。”我快乐的说:“不用谢,叔叔,这是我应该做的,也是我必须要做的。”我提醒这位叔叔:“叔叔,请您记住,保护环境,人人有责,不随地吐痰,也是保护环境的一个表现。”叔叔听了,笑着说:“我会记住的,再见!”“再见!”我开心地说。
我自从做了这件事之后,就亲身感受到保护环境需要我们做好宣传。我想:我一定要继续这样做下去,让我们的环境更加干净。
这是需要我们做好宣传。我想:我一定要继续这样做下去,让我们的环境更加干净。
这是需要大家努力的,如果不努力,那么环境会遭到破坏的.。要不然,人人都会后悔的。
the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.
今天小明和小强一起放学回家,并且谈着今天上课读的《卫生守则》。
这时一位青年男子走了过来,咳嗽了几声“啪”的一下吐了一口痰。小明和小强快步走了上去对青年男子说:“叔叔,你看我们现在的环境多美呀!花儿争先恐后的开着,小草茂盛的生长着,地上没有纸屑干干净净多好看。您吐了一口痰细菌会散播到每个地方的。”“你管的着吗!”青年男子用轻蔑的口气回答并准备走了。小强急忙拦住他又对青年男子说:“叔叔您读过《卫生守则》吗?怎么啦,读没读过关你什么事。爱护公共卫生是我们每一个公民都应该遵守。请您把痰擦掉好吗!”年轻男子无可奈何、极不情愿的想用脚把痰蹭掉。小强递过一块手帕:叔叔用这个擦吧。那男子急忙拿出一张纸把地上的痰擦掉了把纸扔进了垃圾筒里,头也不回的跑了。
垃圾筒仿佛在对他们说:你们真棒!他们低头看看自己胸前的红领巾高兴、快乐的笑了!
一天早晨,小明和小红两人有说有笑地走在上学的路上。
突然,他们看到一位迎面走来的叔叔在路边吐了一口痰,小明和小红连忙走上前去对他说:“叔叔,请您不要随地吐痰”!叔叔听了,不以为然地说:“吐一口痰有什么好大惊小怪的。”小红说:“我们老师说,吐痰不仅是一种不文明行为,也是一种会传播疾病的不卫生的行为。所以,为了这座城市的整洁和大家的健康,请您改正随地吐痰的不良习惯。”小明也指着墙上一张“养成不随地吐痰的好习惯”的标语说:“养成不随地吐痰的好习惯人人有责,它不仅体现了我们的公德心,更反映出一座城市形象”。叔叔听了,惭愧地从口袋里掏出纸巾,蹲下身擦去了地上的痰迹。
小明和小红看了,高高兴兴地对叔叔说:“谢谢您的合作”!
