These 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.

These 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.

这些树林很可爱，又黑又深，但是我必须信守诺言，在我睡觉前还有很长的路要走，在我睡觉前还有很长的路要走。
