宝界山居记

归有光

    ①太湖,东南巨浸也。广五百里,群峰出于波涛之间以百数,而重涯别坞,幽谷曲隈,无非仙灵之所栖息。天下之山,得水而悦;水或束隘迫狭,不足以尽山之奇。天下之水,得山而止;山或孤孑卑稚①,不足以极水之趣。太湖漭淼澒洞②,沉浸诸山,山多而湖之水足以贮之。意唯海外绝岛胜是,中州无有也。故凡屏列于湖之滨者,皆挟湖以为胜。

    ②自锡山过五里湖,得宝界山。在洞庭之北,夫椒、湫山之间。仲山王先生居之。先生早岁弃官,而其子鉴始登第,亦告归。父子并中年失偶,而皆不娶。日以诗画自娱因长洲陆君,来请予为山居之记。

    ③余未至宝界也,尝读书万峰山,尽得湖滨诸山之景,虽地势不同,无不挟湖以为胜。而马迹、长兴,往往在残霞落照之间,则所谓宝界者,庶几望见之。昔王右丞辋川别墅,其诗画之妙,至今可以想见其处。仲山之居,岂减华子冈、欹湖诸奇胜;而千里湖山,岂蓝田之所有哉?摩诘清思逸韵,出尘壒③之外,而不能自引决于开元、天宝之际以濡羯胡④之腥膻。以此知士大夫出处有道,一失足遂不可浣,如摩诘,令人千载有遗恨也。今仲山父子嘉遁于明时⑤,则其于一切世分若太空浮云,曾不足入其胸次矣。何可及哉!何可及哉!

(选自《归有光散文选集》有删节)

【注译】①卑稚:矮小。②漭淼澒洞(hòng tóng):水势广阔浩荡,相连不断。③壒:灰尘。④羯胡:匈奴人的别称,此处代指安禄山。⑤明时:政治清明的时代。

Only a Ribbon

    In one of the London hospitals,a short time ago,there was a young doctor. He noticed one of the patients,a ten-year-old poor girl called Katie,who had a very painful illness.

    Katie lay in her bed,day after day,with nothing to help her forget her pain and cheer up. One day the doctor noticed her trying to make a doll of her finger, and speaking to it. But she was soon tired of it,and lay back into her bed.

    That afternoon,the young doctor saw a beautiful ribbon in a shop window. He thought that it might help cheer the little girl up,so he went in and bought it for her. When he handed the ribbon to the girl,she was too surprised to speak. There were tears in her eyes. This little gift made her feel rich and happy.

    The nurse later told the doctor that the girl played with the ribbon all day long. She twisted(盘绕)it round her head. She held it in her hand while she slept.

    Some weeks later,Katie's illness became worse,and it was necessary to perform a dangerous operation. When Katie was brought into the operation mom,she cried out for the young doctor. He was brought,and he held one of the girl's hands,while the other tightly held the ribbon.

    During the operation,the ribbon fell off Katie's hand. As soon as she woke up and opened her eyes,she looked at her friend and said in a low voice,“My ribbon.”The doctor gave it to her and she smiled happily.

    It was only a little gift,but it made the girl's stay in the hospital bright with beauty and love.
