dreams
by langston hughes
hold fast to dreams
for if dreams die
life is 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 緊緊地
winged 有翅膀的
barren 貧瘠的
frozen 凍結(jié)的，冰冷的
夢想 (朗斯頓·休斯)
緊緊抓住夢想，
夢想若是消亡，
生命就像鳥兒折了翅膀，
再也不能飛翔。
緊緊抓住夢想，
夢想若是消喪，
生命就像貧瘠的荒野，
雪覆冰封，萬物不再生長。
