People travelling long distances frequently have to decide whether they would prefer to go by land, sea, or air.

出远门的人常常需要决定是走旱路、水路，还是坐飞机。

" You will have to go by land, following the shore. It will be longer, but more interesting."

“你必须走陆路，沿着海岸走。它会更长，但更有趣。”

" No; but we have got to the end of that endless sea. Now we shall go by land, and really begin to go down! down! down! "

“不；但是我们已经到了那片无边无际的大海的尽头。现在我们要走陆路，真正开始下降！下降！下降！”
