《大路之歌》是沃爾特·惠特曼的一首著名詩歌，英文原文如下：
```
Afoot and light-hearted I take to the open road,
Healthy, free, the world before me,
The long brown path before me, leading wherever I choose.
Henceforth I ask not good-fortune—I myself am good fortune;
Henceforth I whimper no more, postpone no more, need nothing,
Strong and content, I travel the open road.
The earth—that is sufficient; I do not want the constellations any nearer;
I know they are very well where they are; I know they suffice for those who belong to them.
Still here I carry my old delicious burdens;
I carry them, men and women, I carry them with me wherever I go;
I swear it is impossible for me to get rid of them;
I am fill』d with them, and I will fill them in return.
```
這首詩體現了惠特曼對自由、自然和人類情感的熱愛，以及他對生命和人類經驗的深刻理解。通過這首詩，惠特曼傳達了一種對生活的熱愛和對未來的樂觀態度。
