旅游胜地——南极洲

Antarctica (南极洲) is the coldest place on the earth, but every year thousands of tourists go there. Why do people want to take a vacation there? There are no famous buildings, no hotels and no restaurants. There are some beaches, but nobody wants to go swimming.

Most people go to see the birds, the animals and the amazing scenery (景色). There are seals (海豹) lying on the ice. There are whales swimming in the ocean. You can also watch penguins jumping into the water from icebergs (冰山). It's one of the last untouched places on the planet.

It's possible to visit Antarctica by plane, but most people go there by ship. That's because the ships are comfortable places to stay, and the journey (by sea) is part of the vacation. All tourists visit Antarctica in the summer. In the winter it's too cold for visitors, but in the summer—from November to March—it's warmer than many people think. In some parts of Antarctica in January, it's about 0℃. 　　　

So the temperature can be warmer there than it is in Beijing in January. When you visit there, you don't need to bring a lot of special clothes. Instead, you need to bring sunglasses. The sunshine on the snow and ice is very bright.
