six hours to break my body and soul②.You think I am a very old man—but I am not.It took less than a single③ day to change my hair from black to white.One day，my two brothers and I were coming back from the islands where we often risked④ going and got more fish than others.All at once⑤，the sky was covered with⑥ dark clouds and in less than a minute we were in a terrible storm.A huge wave covered our boat and my younger brother fell into the sea.My elder brother put his mouth close to my ear and cried out⑦ “Moskoe­strom！” The moment I heard the word I became very frightened⑧.[1] I knew what he meant by that one word well enough.[1]the moment引导时间状语从句，表示“一……就……”。With the wind and waves，we were going in the direction of⑨ the whirlpool.We were hopeless⑩.Nothing could save us.I felt sick，as if⑪ I was falling from a mountain top in a dream.We went round and round，nearer and nearer to the horrible edge of the whirlpool.It may appear strange，but at that moment，when we were on the edge of⑫ the whirlpool，I felt calmer⑬ than when we were moving towards it.I began to think how amazing⑭ a thing it was to die in such a way，and how wonderful it was to see the power of nature.Suddenly，we went over the edge.I thought my life was over⑮.But moment after moment passed，and I was still safe.The boat was on the inside of the huge whirlpool and we were going round in circles at great speed⑯.I saw clearly that there were other objects in the whirlpool—trees and barrels⑰.After a while⑱，I became curious⑲ about the whirlpool itself.I then made three important observations⑳.The first，the larger the bodies were，the more rapidly they fell；the second，between two objects of equal extent，round objects fell down less rapidly；and the third，between two objects of the same size，objects shaped like a tube fell down more slowly.So I tied myself to a barrel to help me float.I tried to make my brother understand，but he was too frightened and stayed in the heavy boat.Without waiting，I jumped into the sea to try and escape.As you can see，the reason why I'm here to tell the story is that I made the right decision．[2] Some time after I left the boat，with my brother in it，it was pulled into the bottom of the whirlpool.Soon after that，the whirlpool became less wild.Then the sky was clear，the wind calmer，and the moon was shining.I was still tied to the barrel and the waves soon carried me to an area where the other fishermen were.In the end，a boat picked me up.I was very tired.The fishermen were my old friends，but they were unable to recognise me.When I told them my story，they did not believe it.Now I have told you，and I cannot expect you to believe me any more than the fishermen did.[2]why引导定语从句修饰先行词reason；that引导表语从句。译文参考海上故事大约三年前，我遭遇了一件可怕的事情。就在那一天，我只用了六个小时就伤了我的身心！你认为我很老——但我不是。那件事只用了不到一天的时间就把我的头发从黑变白了。有一天，我们兄弟三人从岛上回来，我们经常冒险去那里捕比别人更多的鱼。突然，天空被乌云笼罩，刹那间，我们就被卷入了可怕的风暴中。一个巨浪覆盖了我们的船，我弟弟掉进了海里。我哥哥把嘴贴近我的耳朵，喊出“莫斯肯漩涡！”我一听到那个词，我变得非常害怕。我很清楚他说的那个词是什么意思。伴随着风浪，我们朝着漩涡的方向前进。我们感到绝望。什么也救不了我们。我觉得恶心，像是在梦中从山顶上掉下来一样。我们转啊转，离漩涡可怕的边缘越来越近。这可能看起来很奇怪，但在那一刻，当我们位于漩涡的边缘时，我感到比我们朝它移动时更镇静。我开始想，以这样的方式死去是多么神奇的一件事啊，能够看到大自然的力量是多么美妙啊。突然我们越过了边缘。我以为我的生命结束了。但时间一刻又一刻过去了，我仍然安然无恙。船在巨大的漩涡里，我们以极快的速度兜圈子。我清楚地看到漩涡里还有别的东西——树和桶。过了一会儿，我开始对漩涡本身感到好奇。然后我做了三个重要的观察。第一，物体越大，下降速度越快；第二，在两个同等面积的物体之间，圆形物体下降得更慢；第三，在两个同样大小的物体之间，像管子一样的物体下降得更慢。所以我把自己绑在一个木桶上帮助我漂浮。我努力使我哥哥明白这一点，但他太害怕了，留在了沉重的木船里。没有再等，我跳进海里尽力逃跑。如你所见，我来这里讲这个故事的原因是我做了正确的决定。在我离开船后的一段时间，我的哥哥还在船上，和小船一起被拉进了漩涡的底部。不久之后，漩涡变得不那么狂野了。这时天空晴朗，风平静下来，月亮也闪耀着。我仍然被拴在木桶上，海浪很快把我带到其他渔民所在的地方。最后，一条船上的人把我救了起来。我很疲惫。渔民们是我的老朋友，但他们没能认出我来。当我告诉他们我的故事时，他们根本不相信。现在我已经把故事告诉你了，我不指望你能相信我，像那些渔民一样。
