by langston hughes

hold fast to dreams for if dreams die life is（请记得收藏本站-一路高升范文网，以获取更多新鲜内容） a broken winged bird that can not fly. hold fast to dreams for when dreams go life is a barren field frozen with snow .

fast 紧紧地 winged 有翅膀的 barren 贫瘠的 frozen 冻结的，冰冷的

梦想 (朗斯顿·休斯) 紧紧抓住梦想， 梦想若是消亡， 生命就像鸟儿折了翅膀， 再也不能飞翔。 紧紧抓住梦想， 梦想若是消丧， 生命就像贫瘠的荒野， 雪覆冰封，万物不再生长。
