There are seven continents﹙洲﹚in the world. Among them, Antarctica﹙南极洲﹚is the most special one. It is a world of snow and ice all year round. China has sent many scientists there. They try to find resources﹙资源﹚under the icy land and study climate change and sea biology.
What do they eat?
Scientists don’t have many choices on what they eat. About 60% their food is frozen food. It is easy to heat﹙加热﹚。Meat is common on the menu, while vegetables are not usual. Fresh vegetables are hard to grow in the cold weather. Therefore, people often eat dried and canned vegetables.
How do they sleep?
In Antarctica, summer lasts from November to March. During this time, Antarctica faces the sun and gets sunlight 24 hours of the day. In order to get some sleep,scientists cover the window with black cloth to make “night”.
How do they work?
People can wear warm clothes to be against the cold weather, but they can do little with the strong wind. Sometimes, the wind is even stronger than a typhoon. It can easily blow people away.
So there are ropes﹙绳索﹚that connect some research stations. People can hold these ropes to keep balance in strong winds.
How do they keep in touch with others?
There are no cables or Internet on the frozen continent. So mobiles and computers don’t work there. Scientists usually use two-way radios to communicate at work. If they want to say hello to family and friends, they can use the satellite phones.
小题1:What do scientists do in Antarctica?
A.They mostly study on the animals and plants there.
B.They mostly find resources and study climate change and sea biology.
C.They mostly find different kinds of lives under the ice and study them.
D.They mostly study on the ice and geography.
小题2:What kind of vegetables do they usually eat?
A.Fresh vegetables
B.Green vegetables only
C.Dried and canned vegetables
D.They go down the ice to work.
小题3:What do they do when the day lasts for 24 hours?
A.They work all day long.
B.They find a way to make “night”.
C.They stop working on those days.
D.They go down the ice to work.
小题4:How do the scientists work on the terrible windy days?
A.They use ropes to help themselves.
B.They just stay in the houses.
C.They use cars and ships to help.
D.They don’t think the wind brings trouble.
小题5:If scientist wants to say “I love you”to her daughter, what can she use?
A.Mobile phonesB.Tow-way radiosC.Satellite phonesD.Iphones and Ipods.

Antarctica is in the most southern part of the world. It is like nowhere else on the earth. It is much larger than Europe, and nearly twice the size of Australia. Antarctica is the coldest and windiest place in the world, even colder and windier than the North Pole. In summer, the sun shines for twenty-four hours a day, but in winter it’s completely dark for about three months. Very few plants grow there, but there is some wildlife, including whales, seals and penguins.
When Captain James Cook traveled around Antarctica in the 1770s by ship, he found no one living there. Today, a few scientists work in Antarctica, but they only spend a short time there.
Many scientists are studying the ozone layer, which is getting thinner and thinner worldwide. The biggest “hole” is above Antarctica, and weather there is getting warmer. Scientists think that this cold and lonely place can teach us a lot about the earth and how to keep the earth safe.

Many animals hide(躲藏) to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes(形状) 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(可怕的). 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(条纹) at once can also confuse(使混乱) animals that want to eat them. Some birds stay in a circle, each toward a different direction.
