lethargy n. 昏睡,瞌睡,无力气
The same lethargy,I am afraid,characterizes the use of all our faculties and senses. Only the deaf appreciate hearing,only the blind realize the manifold blessings that lie in sight. Particularly does this observation apply to those who have lost sight and hearing in adult life. But those who have never suffered impairment of sight or hearing seldom make the fullest use of these blessed faculties. Their eyes and ears take in all sights and sounds hazily,without concentration and with little appreciation. It is the same old story of not being grateful for what we have until we lose it,of not being conscious of health until we are ill. I have often thought it would be a blessing if each human being were stricken blind and deaf for a few days at some time during his early adult life. Darkness would make him more appreciative of sight;silence would teach him the joys of sound.
我担心同样的冷漠也存在于我们对自己官能和意识的运用上。只有聋子才理解听力的重要，只有盲人才明白视觉的可贵，这尤其适用于那些成年后才失去视力或听力之苦的人很少充分利用这些宝贵的能力。他们的眼睛和耳朵模糊地感受着周围的景物与声音，心不在焉，也无所感激。这正好我们只有在失去后才懂得珍惜一样，我们只有在生病后才意识到健康的可贵。 我经常想，如果每个人在年轻的时候都有几天失时失聪，也不失为一件幸事。黑暗将使他更加感激光明，寂静将告诉他声音的美妙。
