【注解】： １、黯黯：同“暗暗”； ２、临洮：今甘肃岷县一带，是长城起点。 ３、咸：都。 【简析】： 写出征战的残酷，具有强烈的人民性和历史的纵深感。语言简炼，极富表现力。这首乐府曲是以长城为背景，描绘战争的悲惨残酷。诗的前四句写塞外晚秋时 节，平沙日落的荒凉景象；后四句写长城一带，历来是战场，白骨成丘，景象荒凉。 全诗写得触目惊心，表达了非战思想。 UNDER A BORDER-FORTRESS Drink, my horse, while we cross the autumn water!- The stream is cold and the wind like a sword, As we watch against the sunset on the sandy plain, Far, far away, shadowy Lingtao. Old battles, waged by those long walls, Once were proud on all men's tongues. But antiquity now is a yellow dust, Confusing in the grasses its ruins and white bones.
