阅读下文，完成下面问题。

　　芋老人者，慈水祝渡人也。子佣出^①，独与妪居渡口。一日，有书生避雨檐下，衣湿袖单，影乃益瘦。老人延入坐，知从郡城就童子试归。老人略知书，与语久，命妪煮芋以进。尽一器，再进，生为之饱，笑曰：“他日不忘老人芋也。”雨止，别去。

　　十馀年，书生用甲第为相国。偶命厨者进芋，辍箸叹曰：“何向者祝渡老人之芋之香而甘也！”使人访其夫妇，载以来。丞、尉闻之^②，谓老人与相国有旧，邀见，讲钧礼^③，子不佣矣。

　　至京，相国慰劳曰：“不忘老人芋，今乃烦尔妪一煮芋也。”已而，妪煮芋进，相国亦辍箸曰：“何向者之香而甘也！”老人前曰：“犹是芋也，而向之香且甘者，非调和之有异，时、位之移人也。相公昔自郡城走数十里，困于雨，不择食矣；今日堂有炼珍^④，朝分尚食^⑤，张筵列鼎，尚何芋是甘乎？老人犹喜相公之止于芋也。老人老矣，所闻实多：村南有夫妇守贫者，织纺井臼，佐读勤苦，幸获名成，遂宠妾媵，弃其妇，致郁郁死，是芋视乃妇也。城东有甲乙同学者，一砚、一灯、一窗、一榻，晨起不辩衣履，乙先得举，登仕路，闻甲落魄，笑不顾，交以绝，是芋视乃友也。更闻谁氏子，读书时，愿他日得志，廉干如古人某，忠孝如古人某，及为吏，以污贿不饬罢^⑥，是芋视乃学也。然则世之以今日而忘其昔日者，岂独一箸间哉^⑦！”

　　老人语未毕，相国遽惊谢曰：“老人知道者！”厚资而遣之。于是芋老人之名大著。（节选自周容《芋老人传》）

　　注：①佣：受雇打工。②丞、尉：知县的佐职。③钧礼：平等之礼。④炼珍：烹制精美的食品。⑤尚食：这里指朝廷赏赐的食品。⑥不饬：不守规矩，行为不端。⑦岂独一箸间：意谓不只辍箸不吃这点事。

Not long ago the movie 2012 came into screen．The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster．Luckily, they are just the director' s imagination, but the present situation is not heading a positive direction, either．

Take my own experience in Alaska as an example．Once I took a trip to the glacier．Along the way there stood signposts marking the snow lines of different years．They started from the foot of the mountain, but it was at the top that I finally saw melting glaciers（融化的冰川）．My heart ached seeing the beautiful blue ice melting at every second．

Sad but true, they are the effects of global warming and the result of our human impact．Furthermore, each year the rising sea level will kill 56 million people, and that' s about the population of the entire Italy．According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water．

Our fortune is in our own hands．It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now．Contribute a little to energy saving by using more efficient light bulbs and less hot water．Let recycle become our habit by thinking twice before throwing something away．Let us take public transportation as our first choice when going to a certain place．It might cost more time for now, but it' s to the benefit of a permanent future．Take care of every tree and grass around us by watering them or simply just avoid destroying them．

In a word, small drops of water make a big ocean． The earth does not belong to us．On the contrary, we belong to the earth． Please bear in mind that the earth is our home．It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality．
