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.
年轻时候的我们,总会面对眼光的事物感到束手无策,害怕过,孤单过,流泪过。可当我们再次站起来时,抬头便会看到最美丽的曙光,那是你的梦想在支撑着你前进,给你无数的勇气,朝着心的方向走,永远不会迷路。
年轻时候的我们,不懂事地以为梦想是多么轰轰烈烈的,一孔之见的.跟别人夸张你的梦。其实不然,梦不分贵贱与轻重,只要是发自内心的梦便一切可以变成梦想,哪怕它是不值一提的,夸夸其谈的,但都别忘了这个梦是从你心灵下采摘下来的,只要你的心是善良的,一切的梦便是好的。只要用心感受过,尝试过,那就是值得人回味一生的东西。
年轻时候的我们,分不清什么是梦想。学习也能成为梦想之中的一部分,友谊也会在梦想中占据很大的一部分,什么亲情友情,什么时光感情。这些人类动物天生就具有的敏感的穴位统统会归属到你的梦想之中。青春时的梦总会天花乱坠,因为它们都还没有成型,需要你自己去滋润它们,劳获它们。
有梦是可贵的,青春年华的梦更加可贵与珍贵。青春年少的我们各自怀揣梦想,装着初有的稚嫩和活力去奋斗,我们总会执着一腔孤勇与青春奋斗……哪怕有一天会迷失在自我的幻想中但只要梦在,一切都还在。
青春年少的我们,梦想是活力的,是可以永不停息的。为了幸福加油,为了活得漂亮不计较任何。不怕最初的梦想会如何如何不管我们飞得多远会有多累有多痛,但我们的青春不会孤单,因为有梦的陪伴。天空永远不会黑,鸟儿永远不会飞得累,白云依旧在天空很白很白……。
因为有梦在,一切都在。
我拥有一颗普通人的心灵,一个普通人的身体,一般人的智商和才能。对,我很普通,可以说是普普通通。
我平凡,但我的梦想并不平凡。它崇高而伟大。那就是当一名志愿者。这个梦想对我来说不是一时兴起,而是意义重大。在我小时候,每当我看到志愿者在帮助困难灾民的时候,我的心情就会十分激动。在512汶川大地震的时候,我看见他们团结一心,众志成城帮助那些灾民们。一些人帮着搬运货物,一些人忙着搭帐篷,些人在救助伤员。他们这样无私的帮助灾民,得到了人们的爱戴。这也许是我的责任感在呼唤我,你是个身体健康、四肢健全的人。你应该去帮助别人,尽自己最大的一份力去为国家、为人民服务!因为是祖国给了我们幸福美好的生活,让我们不再为自己的衣食担忧。还学到了知识。而我们长大了,也该为国家作出点贡献。这可能就是我为什么梦想成为志愿者的原因吧!
你们或许会想:全国有几十万甚至上百万的志愿者。你只是其中一个,算什么?那我会告诉你,在人的一生中,测量你活着是否有意义。并不是看你拥有多少,而是看你付出多少。(当然付出多少就等于拥有多少我当志愿者为人民付出了,就会得到人们的尊重。那这个事业就成功了。现在我就可以想象那时候又苦又幸福的情景了……
为了这一天的到来,我现在要好好学习,自强不息地追逐梦想,用感恩的心报效祖国,帮助我们那些同胞们。
少年强则国强,少年志则国志。我会努力去实现自己的梦想。我的梦想,中国梦,中国梦,中国的梦是我们的梦!
