指导老师：Elf

Boats sail on the rivers，
小舟在河上航行，

And ships sail on the seas;
大船在海中操轮，

But clouds that sail across the sky，
然而白云飘过天空时，

Are prettier far than these.
比这些更为悦人。

There are bridges on the rivers，
河上有桥，

As pretty as you please;

如你所愿的那么悦目；

But the bow that bridges heaven，
然而横跨在穹苍的长虹，

And overtops the trees，
却比树梢更高，

And builds a road from earth to sky，
而能建筑一条通行天际的道路，

Is prettier far than these.
比这些更为美好。
