　　前人栽树，后人乘凉　　

　　范文1：　　

　　The images above are both meaningful and instructive: this man's hard work is not only for his own benefit, but also for the benefit of future generations. 　　

　　The pictures serve to remind us that the existence of our current happiness and valuable national heritage is due to the struggles of our predecessors. 　　

　　We, in turn, should also work hard in order to guarantee the comfort and safety of generations to come. Sustainable development has become a topic of heated debate in recent years. While it is justifiable to satisfy current demands, we cannot neglect the needs of our descendants in the process. Our children also depend on Earth's natural resources and we should not deprive them of such necessities. 　　

　　Unfortunately, many people only think of their shortterm, personal interests. An entire forest might be clearcut, in the interest of making a profit, without a single tree planted in its place. This inconsiderate attitude towards the welfare of our descendants, as well the indifference to the outcome of such reckless actions, can only turn Earth into a cold and lifeless planet. People must be taught to appreciate Earth as not only their home, but also the home of our children and grandchildren, as well as all other plants and animals.　　

　　While making great efforts to increase our current quality of life, we must simultaneously consider how our actions will affect future lives.

　　上面的漫画意味深长而发人深省，栽树人的艰辛劳作不只是为了他自己，也是为了后人。　　

　　这幅漫画是为了提醒我们今天的幸福生活和宝贵的民族遗产归功于我们祖先的奋斗，而我们，反过来，也要努力劳动来确保我们后代的幸福和平安。　　

　　可持续发展是近几年的热点话题，虽然我们要满足自己当前的需要，但不能将子孙后代的需求抛置脑后。我们的孩子同样需要自然资源，我们不能剥夺他们的这份必需品。不幸的是很多人只考虑他们短视的、自私的利益。为了获得利润，整片的森林被砍光，一棵树都不留下。这种不顾及子孙福利的态度，和对这种轻率行为的后果的无动于衷，只会让我们的地球变成一个冷冰冰而无生气的行星。必须告诫人们的是：地球不仅是他们的家园，也是他们的孩子和所有后代的家园，还是其他所有的植物和动物的家园。

　　在努力提高今天的生活质量的同时，我们必须考虑到我们的行为会对未来的生命产生什么样的影响。　　

　　范文2：　　

　　As can be seen from the drawings, the father has planted a small tree thatgrows into a big one and is left to his son to enjoy. Years later, his son sits under the big tree enjoying its shade. 

　　In social development, we should not over utilize our natural resources, as in the case of forests. A reasonable use of forests and reforestation are the best choices in the long run. Human beings should plan ahead when it comes to social development. Even though trees are in short demand today, we must still keep 　　

　　the deforestation under control, for we do not want to eliminate all of our forests, which are essential to our existence. Reforestation is another wise practice. We may not fully benefit from planting trees for the time being, but we must continue doing so, since it will benefit later generations. 　　

　　From the point of view of sustainable development, we have the responsibility to ensure that future generations have enough natural resources to use and arenot penalized for the shortsightedness of present day decision makers. In otherwords, we should not use up our natural resources just to meet our own present day needs, while ignoring the future of our planet.　　

　　译文：　　

　　画中可见，一位父亲种了一棵小树，这棵小树将长成参天大树，他的儿子将会从中受益。多年以后，他的儿子坐在树下享受着大树带来的阴凉。　　

　　在社会发展中，我们不能过度使用自然资源，比如说森林资源。从长远来说对森林的合理利用和植树造林是最好的选择。人类应当为社会发展做长远的打算。尽管木材在当今社会十分短缺，我们也必须控制滥砍滥伐，因为我们不愿看到森林这一人类赖以生存的基础被彻底用尽。植树造林无疑是又一项英明的举措。我们也许暂时不能够充分享受植树给我们带来的益处，但是我们必须继续将这一举措坚持下去，因为它会使我们的后代受益。　　

　　从可持续发展的角度来看，我们有责任来保障后代有丰富的自然资源可利用，并且不会使他们因今天决策者的目光短浅而受到惩罚。换句话说，我们不应该仅为满足我们自己当前的需要而用尽所有的自然资源，忽视我们后代的需求。
