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.
译文：
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。
Have you ever watched a snail move?
A snail leaves behind a slivery trail as it moves.
The slivery trail is slime.
The slime helps the snail slide along.
译文:
你观察过蜗牛爬行吗？
蜗牛爬行时，会留下一条银白色的痕迹。
这条银白色的痕迹是黏液。
黏液有助于蜗牛滑行。
