Unit 1> Caring for Our Earth Passage A Frog Story 蛙的故事 A couple of odd things have happened lately. 最近发生了几桩怪事儿。 I have a log cabin in those woods of Northern Wisconsin. I built it by hand and also added a greenhouse to the front of it. It is a joy to live in. In fact, I work out of my home doing audio production and environmental work. As a tool of that trade I have a computer and a studio. 我在北威斯康星州的树林中有一座小木屋。是我亲手搭建的，前面还有一间花房。住在里面相当惬意。实际上我是在户外做音频制作和环境方面的工作——作为干这一行的工具，我还装备了一间带电脑的工作室。 I also have a tree frog that has taken up residence in my studio. 还有一只树蛙也在我的工作室中住了下来。 How odd, I thought, last November when I first noticed him sitting atop my sound-board over my figured that he(and I say he,though I really don’t have a clue if she is a he or vice versa) would be more comfortable in the greenhouse. So I put him in the greenhouse. Back he came. And stayed. After a while I got quite used to the fact that as I would check my morning email and online news, he would be there with me surveying the world. 去年十一月，我第一次惊讶地发现他（只是这样称呼罢了，事实上我并不知道该称“他”还是“她”）坐在电脑的音箱上。我把他放到花房里去，认为他待在那儿会更舒服一些。可他又跑回来待在原地。很快我就习惯了有他做伴，清晨我上网查收邮件和阅读新闻的时候，他也在一旁关注这个世界。 Then, last week, as he was climbing around looking like a small gray / green human, I started to wonder about him. 可上周，我突然对这个爬上爬下的“小绿人或小灰人”产生了好奇心。 So, there I was, working in my studio and my computer was humming had to stop when Tree Frog went across my stopped and turned around and just sat there looking at ,I sat back and looked at him. For five months now he had been riding there with me and I was suddenly overtaken by an urge to know why he was there and not in the greenhouse,where I figured he’d live a happier frog life. 于是有一天，我正在工作室里干活，电脑嗡嗡作响。当树蛙从我面前爬过时，我不得不停止工作。他停下了并转过身来，坐在那儿看着我。好吧，我也干脆停下来望着他。五个月了，他一直这样陪着我。我突然有一股强烈的欲望想了解他：为什么他要待在这儿而不乐意待在花房里？我认为对树蛙来说，花房显然要舒适得多。 “Why are you here,” I found myself asking him. “你为什么待在这儿？”我情不自禁地问他。 As I looked at him, dead on, his eyes looked directly at me and I heard a tone. The tone seemed to hit me right in the center of my mind. It sounded very nearly like the same one as my computer. In that tone I could hear him “say” to me, “Because I want you to understand.” Yo. That was weird. “Understand what?” my mind jumped in. Then, after a moment of feeling this communication, I felt I understood why he was there. I came to understand that frogs simply want to hear other frogs and to

Unit 1 The Evolving Notion of Home “Home, sweet home” is a phrase that expresses an essential attitude in the United States. Whether the reality of life in the family house is sweet or not so sweet, the ideal of home has great importance for many people. This ideal is a vital part of the American dream. This dream, dramatized in the history of nineteenth-century European settlers of the American West, was to find a piece of land, build a house for one’s family, and start a farm. These small households were portraits of independence: the entire family — mother, father, children, even grandparents — living in a small house and working together to support each other. Everyone understood the life-and-death importance of family cooperation and hard work. Although most people in the United States no longer live on farms, the ideal of home ownership is just as strong in the twentieth century as it was in the nineteenth. When U.S. soldiers came home after World War II, for example, they dreamed of buying houses and starting families. So there was a tremendous boom in home building. The new houses, typically in the suburbs, were often small and nearly identical, but they satisfied a deep need. Many saw the single-family house as the basis of their way of life. For the new suburbanites of the 1950s and 1960s, however, life inside their small houses was very different from life on a farm. First, the family spent much less time together in the house. The father frequently drove, or commuted, as much as an hour to work each morning. The children went to school all day and played after school with neighborhood children. The suburb itself was sometimes called a bedroom community because people used their houses basically for sleeping. Second, the suburb was not a stable community: Families moved frequently as the fathers sought upward mobility — better-paying jobs and bigger houses. Although the idea of home was still as precious as always, it had taken on a different meaning. In the 1970s and 1980s, as more women entered the labor force, the family spent even less time together. But the picture is changing: People can now telecommute, or work at home, while being linked to the office by means of their computers. More and more people can now stay at home. So the old expression could change from

Unit1 蛙的故事最近发生了几桩怪事儿。我在北威斯康星州的树林中有一座小木屋。是我亲手搭建的，前面还有一间花房。住在里面相当惬意。实际上我是在户外做音频制作和环境方面的工作--作为干这一行的工具，我还装备了一间带电脑的工作室。还有一只树蛙也在我的工作室中住了下来。去年十一月，我第一次惊讶地发现他（只是这样称呼罢了，事实上我并不知道该称“他”还是“她”）坐在电脑的音箱上。我把他放到花房里去，认为他呆在那儿会更舒服一些。可他又跑回来呆在原地。很快我就习惯了有他做伴，清晨我上网查收邮件和阅读新闻的时候，他也在一旁关注这个世界。可上周，我突然对这个爬上爬下的“小绿人或小灰人”产生了好奇心。于是有一天，我正在工作室里干活，电脑嗡嗡作响。当树蛙从我面前爬过时，我不得不停止工作。他停下了并转过身来，坐在那儿看着我。好吧，我也干脆停下来望着他。五个月了，他一直这样陪着我。我突然有一股强烈的欲望想了解他：为什么他要呆在这儿而不乐意呆在花房里？我认为对树蛙来说，花房显然要舒适得多。 “你为什么呆在这儿？”我情不自禁地问他。我目不转睛地盯着他，他也直视着我。然后我听到一种叮咚声。这种声音似乎一下子就进入了我的大脑中枢，因为它和电脑里发出来的声音十分接近。在那个声音里我听到树蛙对我“说”：“因为我想让你明白”。唷，太不可思议了。“明白什么？”我脑海中突然跳出了这个问题。然后经过短暂的体验这种交流之后，我觉得我已经理解了树蛙待在这儿的原因。我开始理解树蛙只是想听到其他同类的叫声并并与之交流。或许他误以为计算机发出的声音就是其他树蛙在呼唤他。真是有趣。我继续工作。我正在写一个关于全球气候变化的故事。有个朋友刚好发过来一份传真，说地球的温度正以每十年1.9度的速度上升。我知道，照这种速度下去，每年春天我都爱去提取树浆的这片枫林，到我孩子的那一代就将不复存在。我的故乡美丽的威斯康星州也会在下一代变成一片草原。此刻，树蛙从我脚背跳过去站在电脑前的地板上。然后他伸出手来从后面拢起左耳凝神倾听，接着他又站在电脑前伸出右手拢起另一支耳朵。他这样转动着脑袋，聆听那个声音，非常专心致志。他的皮肤起了微妙的变化，呈现出一种亮丽的绿色，然后他就用尽全力跳到电脑上。我猛然想起去年在收音机里听到的一则关于青蛙的消息，说是全世界的青蛙正在死亡。消息说因为青蛙的皮肤就像是一个内里朝外的肺，所以正在受到污染和全球气候变化的影响。据说已经发现有些青蛙的皮肤已变得像纸一样干瘪。还说青蛙是一个"物种指示器"，由于对环境敏感，这个物种会先遭灭顶之灾。这时我明白了。青蛙向我们传递了一个信息。一些头脑清醒的人士也曾向我们传递过同样的信息，那就是"我们别无选择。"我们已经进入了关键时刻，为了人类的子孙后代，也为青蛙，我们必须对这个星球负起主人的责任。因为我们休戚相关。
