教学参考
Ⅰ.国际知名环保组织介绍
这些国际性的环保组织克服了重重困难，获得了世界范围内的响应和支持，依靠组织手段，将提倡的环保概念普及，并通过各种环保项目的实施，切实推动世界各地的环保进程。

(1)世界环保组织(IUCN)
全名为International Union for Conservation of Nature and Natural Resources ，缩写为IUCN ，该组织历史悠久，1948年即在瑞士格兰德成立，是政府及非政府机构都能参与合作的少数几个国际组织之一。

由全球81个国家、120个政府组织、超过800个非政府组织、10 000个专家及科学家组成，该组织共有181个成员国，实际工作人员已超过8500名。

组织每3年召开一次世界自然保护大会(World Conservation Congress)。

IUCN 旨在影响、鼓励及协助全球各地的协会，保护自然的完整性与多样性，并确保在使用自然资源上的公平性，
及生态上的可持续发展。

(2)世界自然基金会(WWF)
WWF是在全球享有盛誉的、最大的独立性非政府环境保护机构之一，在全世界拥有将近500万支持者和一个在90多个国家活跃着的网络。

WWF的使命是遏止地球自然环境的恶化，创造人类与自然和谐相处的美好未来，保护世界生物多样性；确保可再生自然资源的可持续利用；推动降低污染和减少浪费性消费的行动。

该组织的标志为大熊猫。

(3)全球环境基金(GEF)
GEF是关于生物多样性、气候变化、持久性有机污染物和土地荒漠化的国际公约的资金机制。

GEF通过其业务规划，支持发展中国家和经济转型国家在生物多样性、气候变化、国家水域、臭氧层损耗、土地退化和持久性有机污染物的重点领域上开展活动，取得全球效益。

自1991年启动以来，GEF已通过1000多个项目，向140多个发展中国家和经济转型国家提供了大约40亿美元赠款，并从各种渠道吸引了120亿美元的项目融资。

2002年8月，32个捐资国保证，在随后4年内，向GEF提供近30亿美元，用于GEF活动。

(4)国际绿色和平组织
1971年，12名怀有共同梦想的人从加拿大温哥华起航，驶往安奇卡岛(Amchitka)，去阻止美国在那里进行的核试验。

他们在渔船上挂了一条横幅，上面写着“绿色和平”。

尽管在中途遭到美国军方阻拦，他们的行动却触发了舆论和公众的声援。

次年，美国放弃在安奇卡岛进行核试验。

在此后的30多年里，绿色和平组织逐渐发展成为全球最有影响力的环保组织之一。

该组织继承了创始人勇敢独立的精神，坚信以行动促成改变。

同时，通过研究、教育和游说工作，推动政府、企业和公众共同寻求环境问题的解决方案。

绿色和平组织在中国的环保项目包括气候与能源项目——致力于减缓由燃烧煤、石油和天然气等化石燃料造成的气候变化，还有致力于消除有毒污染物的污染防治项目，森林保护项目品等。

(5)地球之友(Friends of Earth)
在香港地区创立的“地球之友”(Friends of the Earth International)是著名的环境非政府组织之一，还是反全球化运动的一支重要力量。

与其他环境组织一样，“地球之友”近年来也改变了就环境问题谈环境的做法，转而将环境问题与社会问题及发展问题联系起来，既扩大了活动领域，也扩大了影响。

自1983年成立以来，“地球之友”曾经走过一段艰辛的路。

在香港的超级物质主义的大潮流下，“地球之友”仍然坚守使命，捍卫公众利益，维护环境公义，不屈不挠地推动环保，反对扩充发电厂、滥用杀虫剂、侵占郊野土地、关注过度消费、城市空气污染、水质污染、填海和环境管理失误等问题。

Ⅱ.Kids F．A.C.E.(儿童环保组织“为了世界更清洁”)
Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush.Through her own efforts，her letter was reproduced on over 250 donated billboards across the country.
The response to her request for help was so huge that Poe established Kids for A Cleaner Environment(Kids F．A.C.E.)in 1989.There are now 300 000 members of Kids F．A.C.E.worldwide and is the world's largest youth environmental organization.
Poe has also asked the National Par k Service to carry out a “Children's Forest” project in every national park.In 1992，she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the V oices of the Future Program.In 1993，she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started，Kids F．A.C.E.members have distributed and planted over 1 million trees! Ongoing tree－planting projects include Kid's Yards—the creation of backyard wildlife habitats(栖息地)and now Kids F．A.C.E.is involved in the exciting Earth Odyssey，which
is a great way to start helping.
“Starting the club turned out to be a way to help people get involved with the environment.Club members started doing things like recycling，picking up litter and planting trees as well as inviting other kids to join their club.”
“We try to tell kids that it's not OK to be lazy，” she explains.“You need to start being a responsible，environmentally friendly person now，right away，before you become a resource－sucking adult.”
品味人生
1、不管鸟的翅膀多么完美，如果不凭借空气，鸟就永远飞不到高空。

想象力是翅膀，客观实际是空气，只有两方面紧密结合，才能取得显着成绩。

2、想停下来深情地沉湎一番，怎奈行驶的船却没有铁锚;想回过头去重温旧梦，怎奈身后早已没有了归途。

因为时间的钟摆一刻也不曾停顿过，所以生命便赋予我们将在汹涌的大潮之中不停地颠簸。

3、真正痛苦的人，却在笑脸的背后，流着别人无法知道的眼泪，生活中我们笑得比谁都开心，可是当所有的人潮散去的时候，我们比谁都落寂。

4、温暖是飘飘洒洒的春雨;温暖是写在脸上的笑影;温暖是义无反顾的响应;温暖是一丝不苟的配合。

5、幸福，是一种人生的感悟，一种个人的体验。

也许，幸福是你风尘仆仆走进家门时亲切的笑脸;也许，幸福是你卧病床上百无聊赖时温馨的问候;也许，幸福是你屡遭挫折心灰意冷时劝慰的话语;也许，幸福是你历经艰辛获得成功时赞赏的掌声。

关键的是，你要有一副热爱生活的心肠，要有一个积极奋进的目标，要有一种矢志不渝的追求。

这样，你才能感受到幸福。

6、母爱是迷惘时苦口婆心的规劝;母爱是远行时一声殷切的叮咛;母爱是孤苦无助时慈祥的微笑。

7、淡淡素笺，浓浓墨韵，典雅的文字，浸染尘世情怀;悠悠岁月，袅袅茶香，别致的杯盏，盛满诗样芳华;云淡风轻，捧茗品文，灵动的音符，吟唱温馨暖语;春花秋月，红尘阡陌，放飞的思绪，漫过四季如歌。

读一段美文，品一盏香茗，听一曲琴音，拾一抹心情。

8、尘缘飞花，人去楼空，梦里花落为谁痛?顾眸流盼，几许痴缠。

把自己揉入了轮回里，忆起，在曾相逢的梦里;别离，在泪眼迷朦的花落间;心碎，在指尖的苍白中;淡落，在亘古的残梦中。

在夜莺凄凉的叹息里，让片片细腻的柔情，哽咽失语在暗夜的诗句里。

9、用不朽的“人”字支撑起来的美好风景，既有“虽体解吾犹未变兮”的执着吟哦，也有“我辈岂是蓬蒿人”的跌宕胸怀;既有“我以我血荐轩辕”的崇高追求，也有“敢教日月换新天”的豪放气魄。

33 我是一只蜜蜂，
在祖国的花园里，飞来飞去，不知疲倦地为祖国酿制甘甜的蜂蜜;我是一只紫燕，在祖国的蓝天上，穿越千家万户，向祖国向人民报告春的信息;我是一滴雨点，在祖国的原野上，从天而降，滋润干渴的禾苗;我是一株青松，在祖国的边疆，傲然屹立，显示出庄严的身姿。

10、母爱是一滴甘露，亲吻干涸的泥土，它用细雨的温情，用钻石的坚毅，期待着闪着碎光的泥土的肥沃;母爱不是人生中的一个凝固点，而是一条流动的河，这条河造就了我们生命中美丽的情感之景。

11、青春是盛开的鲜花，用它艳丽的花瓣铺就人生的道路;青春是美妙的乐章，用它跳跃的音符谱写人生的旋律;青春是翱翔的雄鹰，用它矫健的翅膀搏击广阔的天宇;青春是奔腾的河流，用它倒海的气势冲垮陈旧的桎梏。

12、失败，是把有价值的东西毁灭给人看;成功，是把有价值的东西包装给人看。

成功的秘诀是不怕失败和不忘失败。

成功者都是从失败的炼狱中走出来的。

成功与失败循环往复，构成精彩的人生。

成功与失败的裁决，不是在起点，而是在终点。

13、母爱是一缕阳光，让你的心灵即便在寒冷的冬天也能感受到温暖如春;母爱是一泓清泉，让你的情感即使蒙上岁月的风尘仍然清澈澄净。

14、不要吝惜自己的爱，敞开自己的胸怀，多多给予，你会发现，你也已经沐浴在了爱河里。

15、奉献是爱心，勇于付出，你一定会收到意外之外的馈赠。

16、人生就像一条河，经历丰富，才能远源流长。

伟大的一生，像黄河一样跌宕起伏，像长江一样神奇壮美。

人生就像一座山，经历奇特才能蔚为大观。

伟大的一生，像黄山一样奇峰迭起，像泰山一样大气磅礴。

经历就是人生的硎石，生命的锋芒在磨砺中闪光;经历就是人生的矿石，生命的活力在提炼中释放。

经历就是体验，经历就是积淀。

没有体验就没有生存的质量;没有积淀，就没有生存的智慧。

人生的真谛在经历中探寻，人生的价值在经历中实现。

17、生命不是一张永远旋转的唱片;青春也不是一张永远不老的容颜。

爱情是一个永恒的故事，从冬说到夏，又从绿说到黄;步履是一个载着命运的轻舟，由南驶向北，又由近驶向远。

18、过去与未来，都离自己很遥远，关键是抓住现在，抓住当前。

19、采一点晨曦，装点一天的清新，捧一把阳光，温暖一季的心情。

雨中潇洒走一回，去释放心底的罗曼蒂克。

一段白云下的遐想，找回的是心灵空间的宽广和飞翔。

听一曲欢快流畅音乐，脸上没有了忧郁的浮云，心中燃烧着一团艳阳。

把笑意写在脸上，人生四季的良辰美景，即如小桥流水，也如风清月明!
20、生命本是一场漂泊的漫旅，遇见了谁都是一个美丽的意外。

我珍惜着每一个可以让我称做朋友的人，因为那是可以让漂泊的心驻足的地方。

有时候会被一句话感动，因为真诚;有时候会为一首歌流泪，因为自然。

要快乐，不止此时，而是一生!。
