Many animals hide to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes help protect them. It’s hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons(变色龙) can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes.

Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary. Some animals will run away from them.

Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger. Seeing many stripes at once can also confuse animals that want to eat them. Some birds stay in a circle, each toward a different direction. In this way they can also help each other stay alive by looking around for animals that many want to eat one of them.

Arctic fox(北极狐) is a kind of small fox that lives in the Arctic. It grows about 50 centimeters long, not including its tail, 30 centimeters tall and weighs from 3 to 7 kilos.

The Arctic foxes are white or blue in color. The white ones are white in winter, but grey-brown in summer. The blue ones are blue-grey all year round. The Arctic foxes have long, thick hair that is called fur. And the long fur covers their whole bodies, including both their cat eyes and rabbit feet, to keep them warm in the low temperature in the Arctic.

The Arctic foxes feed mainly on birds, birds’ eggs and other small animals. Teamwork is the way they look for food, and they don’t like to do that alone.

Baby Arctic foxes are very lovely. They don’t open their eyes until a week after their birth. For the first half of the year, their parents offer them food. They begin to look for food on their own when they are about six months old. The next year they can live alone.

Today, the number of the Arctic foxes is becoming smaller and smaller, because people kill them for their fur to make beautiful coats for money. Something must be done to protect the Arctic foxes.

Hotels can make a person’s stay away from home as restful as possible. Hotels provide warm beds to allow guests a peaceful night’s rest. Besides, some hotels offer guests special services such as newspapers to read in the morning, fresh coffee, and even breakfast. Hotel workers want their guests to feel warm and welcome when they stay in their hotel.
One hotel near the Arctic Circle, however, is different. This hotel gives its guests a cold welcome. The Ice Hotel, in Sweden, is all made of ice. The Ice Hotel might sound strange, but in some ways it is a special hotel. It has a front lobby where guests check into the hotel, plenty of rooms to sleep in, and even room service, which guests can use to have food delivered to their rooms. The Ice Hotel is different, though, because most of the items are made from ice.
It takes more than 30 tons of ice and snow to build the Ice Hotel. It melts(融化) in the summer and is rebuilt each winter. Different builders and artists create the Ice Hotel, so each winter this famous hotel has a new shape and design.
The effort of building the Ice Hotel is worth it, however. Walking into the Ice Hotel is like walking into a diamond. The walls reflect even the smallest bits of light. Ice pillars（柱子）support the roof. The floor below shines like glass. Almost every inch of this hotel sparkles inside. Visiting the Ice Hotel is truly an unusual experience.
Temperatures inside the Ice Hotel are usually below freezing. Guests wear warm jackets, hats, gloves, and thick boots. Even the owners of the Ice Hotel know that staying in a building with walls of ice four feet thick can be a bit cold. They have a solution though. The Ice Hotel has a sauna for its guests. A sauna is a room filled with steam, where guests can warm themselves. In a way, then, one could say that the Ice Hotel does give their guests a warm welcome after all.
