C A year after graduation, I was offered a position teaching a writing class. Teaching was a profession I had never seriously considered, though several of my stories had been published. I accepted the job without hesitation, as it would allow me to wear a tie and go by the name of Mr. Davis. My father went by the same name, and I liked to imagine people getting the two of us confused. “Wait a minute” someone might say, “are you talking about Mr. Davis the retired man, or Mr. Davis the respectable scholar?” The position was offered at the last minute, and I was given two weeks to prepare, a period I spent searching for briefcase (公文包 ) and standing before my fulllength mirror, repeating the words, “Hello, class. I?m Mr. Davis.” Sometimes I would give myself an aggressive voice. Sometimes I would sound experienced. But when the day eventually came, my nerves kicked in and the true Mr. Davis was there. I sounded not like a thoughtful professor, but rather a 12yearold boy. I arrived in the classroom with paper cards designed in the shape of maple leaves. I had cut them myself out of orange construction paper. I saw nine students along a long table. I handed out the cards, and the students wrote down their names and fastened them to their breast pockets as I required. “All right then,” I said. “Okey, here we go.” Then I opened my briefcase and realized that I had never thought beyond this moment. I had been thinking that the students would be the first to talk, offering their thoughts and opinions on the events of the day. I had imagined that I would sit at the edge of the desk, overlooking a forests of hands. Every student would yell. “Calm down, you?ll all get your turn. One at a time, one at a time!” A terrible silence ruled the room, and seeing no other opinions, I inspected the students to pull out their notebooks and write a brief essay related to the theme of deep disappointment. 36.

Actually, the past decades has seen more and more forests disappearing and globe being increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持續(xù)的 ) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources. Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for lowcarbon energy will bee three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now tryuing hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and highspeed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕櫚油 )， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%. Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放 ) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one. The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single pla. That is no small task, but it offers abundant new chances for sustainable product industrie
