Look Ahead 3:
But after sevral hours of hiking through the Alps I did indeed get lost. So it was with some relief that I found myself walking down into a valley towards a country inn. The place was full of people, all with huge Wiener schnitzels on their plates, the area of some of them almost equal to that of Liechtenstein. Suddenly I froze: you find Wiener schnitzels of this size in only one country——Austria. I was now in Austria illegally!
以前学的时候不觉得,现在在Alps跑惯了觉得别有一番趣味

How long could you stand on Antarctic ice before your bare feet froze solid? A minute, maybe two?
If you're an emperor penguin, you can do it for two months, and in wind chills as low as -75 degrees Fahrenheit (-59.4degrees Celsius).
Those naked bird feet may look positively frigid, but their special circulation acts as a kind of antifreeze to keep them just warm enough that they don't freeze.[微风][微风][微风][微风][微风][微风][微风]

Penguins legs and feet have evolved to lose as little heat as possible.
