He did not know that I meant to make a mast and sail.

他不知道我打算装上桅杆和船帆。

As for you, Professor Aronnax, you'll stay in the library two steps away and wait for my signal. The oars, mast, and sail are in the skiff.

阿龙纳斯先生，您就留在离我们两步远的图书室中，等待我的信号。桨、桅和帆都在小艇中。并且我还弄到了一些食物。

Mast and sail flew up in an instant together, and I saw them carried up to prodigious height, resembling in appearance a pterodactyle, one of those strong birds of the infant world.

桅杆和帆瞬间一起飞了起来，我看到它们被带到了惊人的高度，看起来像翼手龙，是婴儿世界中最强壮的鸟类之一。
