地球是我们人类的家园,也是人类的母亲。我们依赖它,探索它。这个蔚蓝色的星球多么美丽,但我们要知道:地球只有一个!
遗憾的是,许多人对于这个浅显易懂的道理却视而不见,继续为所欲为,妄顾地球家园的安危。环境科学家曲格平曾经说过这样一句话:唯有变革,才能拯救人类的命运,也唯有变革,才能使我们的子孙后代世世代代生存下去。里面的变革就是指环保。说得很对,所以如今有许多人拿着标语在街上喊空口号,却没有见过多的'行动。难道这样污染就会好转吗?不!
看,我们城市里的河流的河水发黑发臭;排成长龙的汽车放出大量的废气;成片的绿地变成石屎森林那清脆的鸟叫声消失得无影无踪。如果再这样下去,中国将继续贫乏水资源,空气将变得愈来愈浑浊,本世纪将有10%的鸟类物种消失。上述的事情,我们人类是罪魁祸首!
人人皆知:树木能吸收二氧化碳,排放氧气,净化空气,是我们人类生存的必要的条件。但是有一些人为了金钱去乱砍滥伐树木,造成了过度的水土流失,使大地的植被受到严重的破坏,绿洲和城市也荒漠化,我们人类的生存受到了威胁。就我们平时用的一次性筷子,每天都要耗费数十亩的森林,在那些人眼中,树木除了可以做家具和建筑材料外,似乎没有任何价值。难道还有人不懂树木对我们意味着什么吗我们居住面积已经很小了,如果再这样下去,可能连我们唯一的土地都失去。还有,我们的母亲河黄河近年来河床和含沙量不断增高,成为全国污染最严重的几条江河之一。我们不能眼睁睁地看着黄河从我们手中枯竭,因而有许多环境学者纷纷研究治理黄河污染的方案,试图改善黄河的水质。但如果没有我们的共同参与,我们这个生命的摇篮黄河将会走向衰竭和亡。
如果我们再肆无忌惮地破坏环境,大自然将会给予我们惩罚。那些特大的洪水剥夺了不知多少人的性命,还有由于温室效应,南极北极的冰川融化导致水平面升高,海水淹没了沿海地区,经济损失惨重。难道这不是最好的证明吗
我的家乡广宁是靠竹海生态旅游来发展经济的,而今,某些竹林的环境恶乱不堪,让人叫苦不迭。竹海生态游是我们广宁发展的根,如果根被破坏了,怎能长出茂盛的枝叶、开出美丽的花儿呢
让我们善待人类、善待自然吧!不知大家是否看过《保护环境可做的100件事》这篇文章。其实,我们能做的事很多很多。如,在植树节栽一盆花、种一棵树;保护野生动物,是生态得到平衡;珍惜水资源,不要向江河倾倒垃圾;当环保小卫士,利用每个绿色纪念日宣传环保意识,让青山常在、绿水长流、泥土永芬芳这都是我们力所能及的事情,我们为何不愿意实践呢?
现在,地球的生态环境加剧恶化,环保警世钟已经敲响了。让我们齐齐加入保护环境的行列,创立一个人与大自然和谐共处的美好未来,让人类与自然生生不息地繁衍下去吧。

各位同学:
大家好,我叫XX,我是个XX岁的男孩。为什么叫男孩呢,因为我的心还是很弱小的,没有经过岁月的磨练。我也快是个要成年的男人了,因为我有男人所有的优点,呵呵。
向大家自我介绍,其实我也很为难。因为我自己都不是很了解自己。在别人严重我可能永远是快乐的,乐观的。可是我的内心深处却经常为一些事伤心,焦虑,烦恼,甚至心!我认为正式因为有痛苦才会有快乐,人生好比两杯酒,一杯苦酒,一杯甜酒。只是看你先喝哪一杯。
人生可以分为七个阶段,幼年、童年少年、青年、成年、中年、老年。我们处于青年,是塑造我们人生价值关和目标的`时候,我们以后将要成为一个怎样的人,主要的决定因素都会在接下来的高中三年中发生,所以我很期待以后的高中生活。
2014开学自我介绍范文精选2014开学自我介绍范文精选我喜欢回忆我的少年,回忆我的少年带给我的无数的快乐;而我更向往早点变成一个成年人,因为成年了就能做自己喜欢的事,不再受别人的牵制和约束。
我的自我介绍比较简短,大家是否想和我叫朋友呢?那就来认识认识我吧,我也很希望能和大家交朋友。
尊敬的老师,亲爱的同学们,你们好!
我叫超超,这名字可能有人听说过,也许有人很陌生,但今天的这次介绍,我将要让你们了解我,认识我。我是今年的九月来到XX一中的,毕业XX学校,心中也是满心欢喜。在平时的学习中,动脑筋的问题想得确实很快,在数学、物理等计算上能过得了关,而文史类的读物,我更有我独特的见解。认为时间最宝贵的是生命、时间与精神。认为会感受与思考的不仅使大脑,还有心灵。在这几天中,我认识了一些同学,彼此之间的沟通不仅很融洽,而且增进了友谊。人生地不熟的地方,我去得多了,这不是第一次也不是最后一次,因为我,还会在以后的社会上这个更大的陌生世界去拼搏,去生存,为了给将来打下藤好的基础,所以,今天的我,要比以前更努力。平常我们几乎在用肉眼看这个世界,有人说:这样会看得真,看得失。但我经常用心看这个世界,原来闭上眼睛之后的感受,是那么前所未有的清晰。只提上的感受是比不上精神的振奋的。所以鲁迅弃医从文,也可能是想到了这一点吧。之所以,语文的地位对我来说是更高的一个层次,是精神崛起的寄托。
这就是我,一个思想极为复杂而可望新事物的人,所以对未来,也是想象的并不是很美,但只要我努力去做,相信这个世界对我来说是可以向往的未来。希望能在班上大家能多多指教,谢谢!
I have a great mother. She cares much about me in my life and study.
In the morning, she gets up early to make breakfast for me. When I was little, she prepared my schoolbag. But now, she tells me to do it by myself. Because she thinks I have been old enough to do it. Besides, she always checks my homework. When I finish my homework, she checks it and points out the mistakes. She is very careful and helps me a lot.
I love my mother.

From analyzing users requirements to designing the whole system, from the detailed designing to the final programming, she was very level-headed and full of innovation every step of the way. Taking full advantage of her ability and creativity, she firmly focused herself on her objective and gnored all distractions. She successfully reached her goal. In the final software testing, only a few bugs were found in her subsystem.
