在《基本演绎法》第一季第20级中，华生送给福尔摩斯的。作者是弗罗斯特(Robert Frost)，出处是《Stopping by Woods on a Snowy Evening》 (1923)?

The woods are lovely.

Dark and deep.

But I have promise to keep.

A miles to go befor I sleep.

A miles to go befor I sleep.

——R.Frast

弗罗斯特(Robert Frost)(1874～1963)美国诗人写的。

《Stopping by Woods on a Snowy Evening》 (1923)?

Whose woods these are I think I know.?

His house is in the village though;?

He will not see me stopping here?

To watch his woods fill up with snow.?

My little horse must think it queer?

To stop without a farhouse near?

Between the woods and frozen lake?

The darkest evening of the year.?

He gives his harness bells a shake?

To ask if there is some mistake.?

The only other sound’s the sweep?

Of easy wind and downy flake.?

The woods are lovely, dark, and deep,?

But I have promises to keep,?

And miles to go before I sleep,?

And miles to go before I sleep.?

雪夜林畔小驻?

(译)余光中?

想来我认识这座森林，?

林主的庄宅就在邻村,?

却不会见我在此驻马，?

看他林中积雪的美景。?

我的小马一定颇惊讶：?

四望不见有什么农家，?

偏是一年最暗的黄昏，?

寒林和冰湖之间停下。?

它摇一摇身上的串铃，?

问我这地方该不该停。?

此外只有轻风拂雪片，?

再也听不见其他声音。?

森林又暗又深真可羡，?

但我还要守一些诺言，?

还要赶多少路才安眠，?

还要赶多少路才安眠。
