ASpecialAppointment
Years ago I moved to Woodland Hills to take a job in a small hospital's emergency department. No one wanted to work on New Year's Eve, so the shift(轮班)went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.
At 9 p. m. , the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend New Year with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.
The following year I got New Year's Eve duty again. At 9 p. m. sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr Lee and said, "You probably don't remember me, but last New Year's Eve you saved my life. Thank you for the year you gave me." He and his wife hugged me, handed me a small gift, and left.
The following year a new doctor had joined the group, but I wanted to see if Mr and Mrs Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild.
Mr Lee, his family and I spent 13 New Year's Eves together. In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half-hour each New Year's Eve.
注意:续写词数应为150左右。
Last year I saw Mrs Lee alone in the hospital with a gift for me.
……
I carefully opened the package and found a crystal(水晶)bell inside with the word "Friendship" engraved(雕刻) on it.
胡谐之,豫章南昌人也。祖廉之,治书侍御史。父翼之,州辟.不就。谐之初辟州从事主簿,临贺王国常侍,抚军行参军,晋熙王安西中兵参军,南梁郡大守。以器局见称。徙邵陵王南中郎中兵,领汝南太守,不拜。除左军将军,不拜。
世祖屯盆城,使谐之守寻阳城,及为江州,复以谐之为别驾,委以事任。文惠太子镇襄阳,世祖以谐之心腹,出为北中郎征虏司马,爵关内侯。在镇毗赞,甚有心力。建元二年,还为骁骑将军,转黄门郎,领羽林监。永明元年,转守卫尉。明年,加给事中。三年,迁.散骑常侍。
谐之风形瑰润,善自居处,兼以旧恩见遇,朝士多与交游。六年,迁都官尚书。上欲迁谐之,尝从容谓谐之曰:“江州有几侍中邪?”谐之答曰:“近世唯有程道惠一人而已。”上曰:“当令有二。”后以语尚书令王俭,俭意更异,乃以为太子中庶子,领左卫率。
谐之兄谟之亡,谐之上表曰:“臣私门罪衅早备荼苦兄弟三人共相抚鞠婴孩抱疾得及成人长兄臣谌之复早殒没。与今亡第二兄臣谟之衔戚家庭,得蒙训长,情同极荫,何图一旦奄见弃放,吉凶分违,不获临奉,乞解所职。”诏不许。
八年,上遣谐之率禁兵讨巴东王子响于江陵,兼长史行事。为子响所败,有司奏免官,权行军事如故。复为卫尉,领中庶子。谐之有识计,每朝廷官缺及应迁代,密量上所用人,皆如其言,虞悰以此称服之。十年,转度支尚书。明年,卒,年五十一。赠右将军、豫州刺史。谥曰肃。
