我说不出这心为什么那样默默地颓丧着。
是为了它那不曾要求，不曾知道，不曾记得的小小的需要。
I cannot tell why this heart languishes in silence.
It is for small needs it never asks, or knows or remembers.夏天的飞鸟，飞到我的窗前唱歌，又飞去了。
秋天的黄叶，它们没有什么可唱，只叹息一声，飞落在那里。
Stray birds of summer come to my window to sing and fly away.
And yellow leaves of autumn, which have no songs, flutter and fall there with a sign.

户外一片灰暗，天空低低的，好像要贴到屋顶上。一会儿前还鸟雀喧嚷的老榆树上只剩下零落的声音。
Why is it always at dusk when we head to the grocery?It is gray outside and the sky is so low that it seems to be touching the roof.The old elm tree, where the birds had been clamoring a while ago, is now left with only fitful sounds.
