俯在头顶的悬崖

波莉继续往下走。这时她发现了一件奇怪的事：天空比刚才少了。她抬头看，悬崖伸了出来，悬在她头顶上。上面比下面宽。崖顶的小城现在看不见了。

Polly goes further down. Then she notices something strange. There is less sky than before. She looks up. The cliff hangs out over her head. It is wider up there than down here. The town at the top is out of sight now.

这是大海做的，在很长很长的时间里慢慢做成的。海浪拍打悬崖的底部，把石头一点点带走。这样一来，上面的石头下面就空了。沿着这段海岸，大海在悬崖上冲出了很大的洞穴。海浪冲进洞里的时候，波莉能通过脚下的石头感觉到那声音。

The sea did this, slowly, over a very long time. Waves hit the bottom of the cliff and take the rock away. Then the rock above has nothing to stand on. Along this coast the sea has made big caves in the cliffs. When a wave goes into a cave, Polly feels the sound through the stone under her feet.

在她下面的岩架上，有一些墨绿色的鸟。它们站着，把翅膀张得很开，在风里吹干。这些鸟叫欧鸬鹚。整个地中海的欧鸬鹚，差不多有一半在这段海岸和远处的小岛上筑巢。

On the ledges below her there are dark green birds. They stand with their wings wide open to dry them in the wind. These birds are shags. Almost half of all the shags in the whole Mediterranean Sea nest along this coast and on the small islands out there.

突然，其中一只从岩架上掉了下去。它落进水里，几乎没有溅起水花。波莉等着。那只鸟在水下待了很久。再出来的时候，它已经在很远的地方了，嘴里还有一条鱼。

Suddenly one of them drops off its ledge. It falls into the water and makes almost no splash. Polly waits. The bird stays under a long time. When it comes up again it is far away, and it has a fish.
