265. 夜上受降城闻笛（李益）
正文
现代汉语译文
正文
回乐峰前沙似雪，受降城外月如霜。
现代汉语译文
回乐峰前，沙地在月光下白得像雪；受降城外，月色清冷如同霜。
“回乐峰”是回乐县附近的山峰；“受降城”是唐代北方的边城。“沙似雪”“月如霜”都因月色惨白而生出的比喻，写边地夜晚的荒寒，并非真有霜雪。
正文
不知何处吹芦管，一夜征人尽望乡。
现代汉语译文
不知从哪里传来了芦管的吹奏声；这一整夜，所有的戍边将士都向着故乡遥望。
“芦管”是芦笛一类的边地乐器。“不知何处”写笛声来处不明，因而更显苍茫。“尽”字写思乡的人多、心情相同；“一夜”写时间之长，说明无人能够入睡。

颜色先造出寒意 · Cold Made First by Color
前两句不写风，也不写温度，只把沙写成雪、把月写成霜。白茫茫的颜色先让读者感到冷，边地的荒凉与孤寂也随之而来。景是静的，人的情绪却在这片静里一点点凝重起来。
The opening lines mention neither wind nor temperature; they turn sand into snow and moonlight into frost. The sheer whiteness makes the reader feel cold first, and the desolation of the frontier follows. The scene is still, yet within that stillness the soldiers' feeling grows steadily heavier.
一支笛子让所有人转向故乡 · One Pipe Turns Everyone Homeward
前两句的静，到第三句被一支芦管打破。谁在吹、吹的是什么曲子，诗都没有说；正因为来处不明，笛声才像从四面八方同时响起。末句的“尽”把个人的乡愁变成整支队伍的乡愁，“一夜”又把这一刻延长到天亮。
The stillness of the opening is broken by a single reed pipe. Who plays it and what tune it is the poem never says; precisely because its source is unknown, the sound seems to rise on every side at once. The word every turns one man's homesickness into the homesickness of an entire garrison, and all night long stretches the moment until dawn.
