I don’t know how many days I have been given to spend, but I do feel my hands are getting empty. Taking stock silently, I find that more than eight thousand days have already slid away from me. Like a drop of water from the point of a needle disappearing into the ocean, 我的日子滴在時間的流里，沒有聲音也沒有影子。
　　單詞提示：
　　needle n. 針；
　　答案：
　　my days are dripping into the stream of time, soundless, traceless.
　　本句節選自朱自清《匆匆》
　　總結：
　　1.滴落很多人用了drop into, 還有的用了flow 或是disappear都不如drip into 描述的更準確.
　　2.如果沒有影子shadowless 應該也可以吧，回復中大多數人比較習慣用 no shadow，希望我的總結可以拓寬你翻譯的思路。
