       余幼时即嗜学。家贫，无从致书以观，每假借与藏书之家，手自笔录，计日以还。天大寒，砚冰坚，手指不可屈伸，弗之怠。录毕，走送之，不敢稍逾约。以是人多以书假余，余因得遍观群书。既加冠，益慕圣贤之道。又患无师名人与游，尝趋百里外，从乡之先达执经叩问。先达德隆望尊，门人弟子填其室，未尝稍降辞色。余立侍左右，援疑质理，俯身倾耳以请；或遇其叱咄，色愈慕，礼愈至，不敢出一言以复；俟其欣悦，则又请焉。故余虽愚，卒获有所闻。

       铨^①九龄，母授以《礼记》、《周易》、《毛诗》，皆成诵；暇更录唐宋人诗，教之为吟哦声。铨每病，母即抱铨行一室中，未尝寝；少痊，辄指壁间诗歌，教儿低吟之以为戏。母有病，铨则坐枕侧不去。母视铨，辄无言而悲。铨亦凄楚依恋，尝问曰：“母有忧乎？”曰：“然！”“然则何以解忧？”曰：“儿能背诵所读书，斯解也。”铨诵声琅琅然，争药鼎沸^②。母微笑曰：“病少差^③矣。”由是母有病，铨即持书诵于侧，而病辄能愈。

    The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so

that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to

each other forever. He sent camera team out one evening to film the sunset for him.

    The next morning he said to the men, "Have you provided me with that sunset?"

    "No, Sir," the men answered.

    The director was angry.

    "Why not?" he asked. "Well," one of the men answered, "we are on the east coast here, and the sun sets

in the west. We can get you a sunrise over the sea, if necessary, but not a sunset."

     "But I want a sunset!" the director shouted. "Go to the airport, take the next flight to the west coast, and

get one."

     But then a young secretary had an idea. "Why don't you photograph a sunrise," she suggested, "and then

play it backwards, Then it'll look like a sunset." "That's a very good idea!" the director said. Then he turned

to the camera team and said, "Tomorrow morning I want you to get me a beautiful sunrise over the sea."

    The camera team went out early the next morning and filmed a bright sunrise over the beach in the middle

of a beautiful bay. Then at nine o'clock they took it to the director. "Here it is, Sir," they said, and gave it to

him. He was very pleased.

    They all went into the studio. "All right," the director explained, "now our hero and heroine are going to

say goodbye. Run the film backwards so that we can see the sunset behind them."

     The "sunset" began, but after a quarter of a minute, the director suddenly put his face in his hands and

shouted to the camera team to stop.

    The birds in the film were flying backwards away from the beach.
