Lesson55

　　【课文】

　　Recent developments in astronomy have made it possible to detect planets in our won Milky Way and in other galaxies. This is a major achievement because, in relative terms, planets are very small and old not emit light. Finding planets is proving hard enough, but finding life on them will prove infinitely more difficult. The first question to answer is whether a planet can actually support life. In our won solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than four billion years for plant and animal life to evolve.

　　Whether a planet can support life depends on the size and brightness of its star, that is its 'sun'. Imagine a star up to twenty times larger, brighter, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life. Alternatively, if the star were small, the life-supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we find such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. The development of such a telescope will be one of the great astronomical projects of the twenty-first century.

　　It is impossible to look for life on another planet using earth-based telescopes. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets. Even a telescope in orbit round the earth, like the very successful Hubble telescope, would not be suitable because of the dust particles iron solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space, because the dust becomes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet, we would have to find a way of blotting out the light from its star, so that we would be able to 'see' the planet properly and analyze its atmosphere. In the first instance, we would be looking for plant life, rather than 'little green men'. The life forms most likely to develop on a planet would be bacteria. It is bacteria that have generated the oxygen we breathe on earth. For most of the earth's history they have been the only form of life on our planet. As Earth-dwellers, we always cherish the hope that we will be visited by little green men and that we will be able to communicate with them. But this hope is always in the realms of science fiction. If we were able to discover lowly forms of life like bacteria on another planet, it would completely change our view of ourselves. As Daniel Goldin of NASA observed, 'Finding life elsewhere would change everything. No human endeavor or thought would be unchanged by it."

　　天文学方面最新发展使得我们能够在银河系和其他星系发现行星。这是一个重要的成就，因为相对来说，行星很小，而且也不发光。寻找行星证明相当困难，但是要在行星上发现生命会变得无比艰难。第一个需要解答的问题是一颗行星是否有能够维持生命的条件。举例来说，在我们的太阳系里，对于生命来说，金星的温度太高，而火星的温度则太低。只有地球提供理想的条件，而即使在这里，植物和动物的进化也用了40亿年的时间。

　　一颗行星是否能够维持生命取决于它的恒星——即它的“太阳”——的大小和亮度。设想一下，一颗恒星比我们的太阳还要大，还要亮，还要热20倍，那么一颗行星为了维持生命就要离开的它的恒星非常远。反之，如果恒星很小，维持生命的行星就要在离恒星很近的轨道上运行，而且要有极好的条件才能使生命得以发展，但是，我们如何才能找到这样一颗行星呢?现在，没有一台现存的望远镜可以发现生命的存在。而开发这样一台望远镜将会是21世纪天文学的一个重要的研究课题。

　　使用放置在地球上的望远镜是无法观察到其他行星的生命的。地球周围温暖的大气层和望远镜散出的热量使得我们根本不可能找到比行星更小的物体。即使是一台放置在围绕地球的轨道上的望远镜——如非常成功的哈勃望远镜——也因为太阳系中的尘埃微粒而无法胜任。望远镜要放置在木星那样遥远的行星上才有可能在外层空间搜寻生命。因为我们越是接近太阳系的边缘，尘埃就越稀薄。一旦我们找到这样一颗行星，我们就要想办法将它的恒星射过来的光线遮暗，这样我们就能彻底“看见”这颗行星，并分析它的大气层。首先我们要寻找植物，而不是那种“小绿人”。行星上最容易生存下来的是细菌。正是细菌生产出我们在地球上呼吸的氧气。在地球上发展的大部分进程中，细菌是地球上的生命形式。作为地球上的居民，我们总存有这样的希望：小绿人来拜访我们，而我们可以和他们交流。但是，这种希望总是只在科幻小说中存在。如果我们能够在另一颗行星上找到诸如细菌的那种低等生命，那么这个发现将彻底改变我们对我们自己的看法。正如美国国家航空和宇宙航空局的丹尼尔.戈尔丁指出的“在其他地方发现生命会改变一切。任何人类的努力和想法都会发生变化。”

Lesson56

　　【课文】

　　The river which forms the eastern boundary of our farm has always played an important part in our lives. Without it we could not make a living. There is only enough spring water to supply the needs of the houses, so we have to pump from the river for farm use. We tell river all our secrets. We know instinctively, just as beekeepers with their bees, that misfortune might overtake us if the important events of our lives were not related to it.

　　We have special river birthday parties in the summer. Sometimes we go upstream to a favourite backwater, sometimes we have our party at the boathouse, which a predecessor of ours at the farm built in the meadow hard by the deepest pool for swimming and diving. In a heat wave we choose a midnight birthday party and that is the most exciting of all. We welcome the seasons by the riverside, crowning the youngest girl with flowers in the spring, holding a summer festival on Midsummer Eve, giving thanks for the harvest in the autumn, and throwing a holy wreath into the current in the winter.

　　After a long period of rain the river may overflow its banks. This is a rare occurrence as our climate seldom guest to extremes. We are lucky in that only the lower fields, which make up a very small proportion of our farm, are effected by flooding, but other farms are less favorably sited, and flooding can sometimes spell disaster for their owners.

　　One bad winter we watched the river creep up the lower meadows. All the cattle had been moved into stalls and we stood to lose little. We were, however, worried about our nearest neighbors, whose farm was low lying and who were newcomers to the district. As the floods had put the telephone out of order, we could not find out how they were managing. From an attic window we could get a sweeping view of the river where their land joined ours, and at the most critical juncture we took turns in watching that point. The first sign of disaster was a dead sheep floating down. Next came a horse, swimming bravely, but we were afraid that the strength of the current would prevent its landing anywhere before it became exhausted. Suddenly a raft appeared, looking rather like Noah's ark, carrying the whole family, a few hens, the dogs, cat, and bird in a cage. We realized that they must have become unduly frightened by the rising flood, for their house, which had sound foundations, would have stood stoutly even if it had been almost submerged. The men of our family waded down through our flooded meadows with boathooks, in the hope of being able to grapple a corner of the raft and pull it out of the current towards our bank. We still think it a miracle that they we able to do so.

　　形成我们农场东部边界的一条河流一直在我们生活中发挥着重要作用。要是没有这条河，我们就无法生存下去。泉水只能满足家庭生活用水，因此我们必须从河里抽水以用于农业生产。我们向那条河倾诉我们的秘密。我们本能地懂得，就像养蜂人和他的蜜蜂那样，要是我们不把生活中的重大的事件告诉那条河，就可能大祸临头。

　　夏天，我们为这条河举办特殊的生日宴会。有时，我们溯流而上来到我们喜爱的回水河汊举办;有时在船坞举办。那船坞是农场一位前辈在一块草地上盖的，草地紧挨着一个专供游泳、跳水的深水池。天气炎热时，我们便选择在半夜举办生日聚会，这种聚会是最令人激动的。我们在河边迎接一年四季。春天在河边为最年轻的姑娘戴上花冠，夏天在河边欢庆“仲夏前夜”，秋天在河边丰收而感恩，冬天往河中抛撒一个冬表花环。

　　久雨这后，河水会泛滥成灾，但是在我们这里，气候很少发生异常，河水极少泛滥。值得庆幸的是，只有低洼的受到洪水影响，而低洼地在我们农场比例很小。其他农场地势欠佳，洪水有时会给农场主带来灾难。

　　有一年冬天，天气不好，我们眼看着河水浸没了地势较低的草场。所有的牲口已提前转移到畜圈里，没有造成什么损失。不过，我们很为我们的近邻担心。他们的农场地势低洼，而且他们又新来乍到。由于洪水造成了电话中断，我们无法了解他们情况。从顶楼窗口看去，我们农场与他们农场接壤处的那段河流一览无余。在最紧急的时刻，我们轮流监视那段河流的险情。灾难的第一迹象是一只死羊顺流而下，接着一匹活马勇敢地与水搏击。但我们担心，洪水力量将使它上岸之前就筋疲力尽了。突然，出现了一只筏子，看起来很像诺亚方舟，上面载着他们全家老小，还有几只母(又鸟)、几只狗，一只猫与一只鸟笼，那里头有一只小鸟。我们意识到他们一定是被不断上涨的洪水吓坏了。因为他们的房子地基牢固，即使洪水几乎灭顶也不会倒塌。我家的男人们手拿船篙过被水淹没草场，希望能够钩住筏子一角，将它拽出激流，拖回岸边。他们终于成功了。至今我们仍认为这是个奇迹。

Lesson57

　　【课文】

　　I stopped to let the car cool off and to study the map. I had expected to be near my objective by now, but everything still seemed alien to me. I was only five when my father had taken me abroad, and that we eighteen years ago. When my mother had died after a tragic accident, he did not quickly recover from the shock and loneliness. Everything around him was full of her presence, continually reopening the wound. So he decided to emigrate. In the new country he became absorbed in making a new life for the two of us, so that he gradually ceased to grieve. He did not marry again and I was brought up without a woman's care; but I lacked for nothing, for he was both father and mother to me. He always meant to go back on day, but not to stay. His roots and mine bad become too firmly embedded in the new land. But he wanted to see the old folk again and to visit my mother's grave. He became mortally ill a few months before we had planned to go and, when he knew that he was dying, he made me promise to go on my own.

　　I hired a car the day after landing and bought a comprehensive book of maps, which I found most helpful on the cross-country journey, but which I did not think I should need on the last stage. It was not that I actually remembered anything at all. But my father had described over and over again what we should see at every milestone, after leaving the nearest town, so that I was positive I should recognize it as familiar territory. Well, I had been wrong, for I was now lost.

　　I looked at the map and then at the millimeter. I had come ten miles since leaving the town, and at this point, according to my father, I should be looking at farms and cottages in a valley, with the spire of the church of our village showing in the far distance. I could see no valley, no farms, no cottages and no church spire -- only a lake. I decided that I must have taken a wrong turning somewhere. So I drove back to the town and began to retrace the route, taking frequent glances at the map. I landed up at the same corner. The curious thing was that the lake was not marked on the map. I left as if I had stumbled into a nightmare country, as you sometimes do in dreams. And, as in a nightmare, there was nobody in sight to help me. Fortunately for me, as I was wondering what to do next, there appeared on the horizon a man on horseback, riding in my direction. I waited till he came near, then I asked him the way to our old village. He said that there was now no village. I thought he must have misunderstood me, so I repeated its name. This time he pointed to the lake. The village no longer existed because it had been submerged, and all the valley too. The lake was not a natural one, but a man-made reservoir.

　　我停下车，让汽车发动机冷却一下，同时查看一下地图。我本想离目的地已经不远，但周围一切对我仍很陌生。我5岁那年，父亲就带我出了国，那是18年前的事了。当时我母亲在一次事故中惨死，父亲未能很快从悲痛与孤独中恢复过来。他身边的一切都是母亲的影子不断勾起他的伤感。于是他决定移居他国。在这个新的国家里，父亲专心致志地为我们俩开创一种新的生活，慢慢地不伤心了。父亲没有再娶，因此，我在没有母亲的环境里长大成人。但我却什么都不缺，他既当父亲又当母亲。他总想将来回国看看，但却不愿长期住下去，因为他与我一样已经把根深深地扎在异国的土地上。 但是，他想看一看家乡父老乡亲，为我的母亲扫墓。就在他计划回国的前几个月，他突然身患绝症。他知道自己已奄奄一息，于是他要我答应一定单独回故乡一趟。

　　我下飞机后租了一辆车，并买了一本详尽的地图册。在乡间行车途中，我觉得它非常有用，但快到家了，我倒觉得它没什么用了。这倒并非是我背熟了地图，而是父亲曾详细给我讲了，在过了离故乡最近的那个小镇后，在每一个路标处可见到些什么。因此，我相信这段路对我来说会是很熟悉的。唉，实际我错了，我现在迷路了。

　　我看了看地图，又查了一下里程表。从小镇出来，我走了10英里。照父亲的说法，我面前应是一个山谷，有农场与村舍，还可远远望见老家村子里的教堂的尖顶。可现在我却看不出山谷，看不见农舍，也看见教学尖顶，看见只是一片湖泊。我想一定是什么地方拐错了弯儿。于是我驾车返回小镇，重新按路线行驶。结果又来到刚才那个拐弯处。奇怪的是那个湖没有在地图上标出。我感到自己就像平时作梦那样迷迷糊糊地闯进了恶梦境地。就像在恶梦里一样，见不到一个人可以帮助我。不过，我是幸运的，正当我走投无路之时，从天边出现一个骑马的人向我骑来。等他走近了，问他去老家的路。他说那村子已经没有了。我想他一定误解了我的意思，于是又说一遍村庄的名字。这次他用手指了一下那个湖。村庄已不复存在，因为已经为水所淹，山谷也被水淹没了。这不是一个天然湖泊，是一座人工修建的水库。
