从第一个海藻类动物出现,地球上的生物已经在这个蓝色的星球上演化了几十亿年。在这个我们赖以生存的地球上,牢刻着多少动物的脚印?大自然的鬼斧神工曾经打造过多少生灵?他们在这个窄小的“栖息地”里竞争、生存、繁延、生息,他们在这样一个弱肉强食的世界里,我们的祖先以聪明的头脑生存了下来。
经过几千年的演变和进化,我们拥有了极高的科技水平,但是,某些观点是没有科学依据的。比如蚊子,它是人人都讨厌的东西,还有一些人甚至认为:如果没有蚊子了,我们的'生活将会变得更好!但是,你曾想过,蚊子和我们的生活息息相关。
假如自然界没圾蚊子,将会发生怎样的情况呢?蜻蜓的幼虫在水里生长,是靠吃蚊子的幼虫生存的。假如没有蚊子蜻蜓的幼虫就会饿,久而久之,蜻蜓就会灭绝。一些靠蜻蜓生存的生物也难逃灭绝的命运。以此类推,将会牵连一大片,许多生物就会因此灭绝。就好比一串鞭炮,只要点燃其中一个,其它的也会被点燃。假如世界上没有蚊子,人类的生活不会变得更好,反而更坏。
我们人类亲手缔造了一个高度的文明,但有得必有失。随着人类工业化的发展,一条条清澈的小溪变成了臭水沟;一片片碧绿的森林变成了一个个荒凉的沙漠。从十八世纪起,人类的活动严重破坏发大自然生态环境。人类排放的污水源源不断的流向大海,1/4的海水被污染过;排放的废气升上了天空,产生了温室效应,使两极冰层融化,使海平面上升,沿海房屋被淹没,一些生活在两极的动物无家可归。人类还大量捕捉鱼、鲸、老虎、狮子……使很多物种绝迹,严重破坏了生物链、食物链。不仅如此,人类还无休止的砍伐树木,现在我们尝到了应有的痛苦了,自然灾害频繁爆发。比如黄河边经常决堤,闹得两岸百姓叫苦不迭;北京经常刮起沙暴,这是大自然的怒吼,是对我们敲响的警钟!
题记:
早凉渐水冷寒心,海懒天闲绝啸音。
刹那火轮乘浪起,风翻揉碎满怀金。
《七绝·海上日出》曹嵩
在这个世界上,有许多奇观出现在我们的生活中。有的是罕见的日食,有的是奇特的流星,有的是黄昏美丽的朝霞……而我要介绍的则是海上日出。
那是去年暑假,我在海滨度假。为了看日出,我特地起了个大早。除了周围潮湿的海水的声音,周围特别宁静。
天还蒙蒙亮,东方泛着一点儿一点儿鱼肚色的天空,染上一点淡蓝色,浅蓝中带一点儿白的云朵在高空中自由飘浮。海风呜呜地吹向沙滩,好像在演奏一首美妙的乐曲,又好像一个小女孩正在伤心的'哭泣。
天空还是之前的浅蓝,但天边出现了一道红霞,慢慢地扩大它的范围,增加它的亮光,最终使周围的云朵也终于有了亮光。
只见太阳在海平面露出半张红彤彤的脸,好像一个调皮的满面红光的孩子在玩捉迷藏。渐渐地太阳升起来了,它好似背着重物一样一点一点往上升。到了最后,太阳完全跳出了海平面,射出千万道金光。顿时,海天相接,出现了一条金色的长带。在灿烂阳光的照耀下,如一条巨龙在海里翻滚。
远眺天空,天空中飘着红紫红紫的彩云。有的像紫禁城前的石狮孑,威武地望着远方。有的像在水里欢快游动的鱼儿,有的像一匹骏马,正在奔驰在一望无际的大草原上……
太阳继续冉冉升起,一幢幢建筑物在沙滩上投下了一个个黑影,好像即将倒下的诺米骨牌。太阳好像一位技艺高超的画家,把天空描绘成一副浓妆淡抹的水彩画。海浪在太阳的照射下,发出万点金光,真像一粒粒黄金。一轮红日正从海平面升起,海风轻轻地吹着。远洋的渡轮在海面快速地驶过。阳光隐隐约约地从轮船上显响出来,有时候还发出汽笛声。好像一只巨大的鲸鱼在海面上狂欢,这真是一个伟大的奇观!
海上日出很美,它那种昂扬向上的精神也应值得我们学习。

As is shown above, a leader father is sitting in the chair with a seal grasping in the hand, and a lot of money beside him. He seriously said to his son that there is more to life than just money -it is power. Simple as the picture is, but a profound truth is reveled in the picture.
I surely disagree with father ’s philosophy. As a leader, he shouldn ’t use his power to make money. It is his duty to serve people wholeheartedly, just one person said “with great power comes great responsibility ”. If he stick to his philosophy. I believe that he will spend the rest of his life in prison. What’s worse, he could affect his son ’s philosophy, guiding him in the opposite direction , nothing can be done to reverse the trend itself. The only solution is to change father ’s philosophy. Because of many greedy officials in China, it is time to reverse the trend itself by establishing new policy. As Chinese always has been our confidence that we can change for the better and better.
In my opinion, there is more to to life than just money -it is happiness, nothing is important than happiness. We can live a colorful life in our spare time.

7月22日上午9时左右,发生了21世纪以来最壮观的一次日全食,我们这里是最佳的观测地。
上午,我们早早的吃好了早餐,爸爸说要带我去看日食,还让我带上墨镜,我很好奇日食是什么?爸爸告诉我:“日食是太阳被月球遮住的现象。月球在绕地球运行过程中,有时会走到太阳和地球的中间,这时月球的影子落到地球表面上,位于影子里的观测者便会看到太阳被月球遮住,这就是日食。”据说今天在中国可以看到一次罕见的日全食。爸爸还上网给我看了相关的资料和图片,让我增长了许多知识。
9点半左右我们一家三口来到小区空旷的草地上,抬头看太阳,可惜太阳被乌云遮住了。妈妈建议到18楼顶楼上看看。幸亏有电梯,一下子到了18楼。望着被层层乌云包围的太阳,我们有些失望。等了一会儿,乌云散去。再到阳台一看,往日圆圆的太阳竟然少了二分之一!日食,真的是日食,我激动得要跳起来了,要知道,日食要两三百年才能在同一地方出现,天哪,我居然在十二岁前就看到了日全食,这可是一个了不起的事情!
看,太阳在一点一点的缩小。先是变作小船,然后变作柳叶眉,最后只剩下了一个底,天空突然暗下来,一切显得那么神秘。
接着,太阳慢慢变大,慢慢变圆,天空开始复原成往日的样子。
日全食,真的好美。
