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.

Feeling lonely can make you sick. Doctors have long known that loneliness can cause many health problems and even death. What they didn’t know is   16  this feeling causes illness. A study in the online magazine Genome Biology  17  that loneliness actually influences the important part of our bodies—our genes.
In a small population of patients, researchers   18  more than 20,000 genes to compare how the genes of lonely and non-lonely individuals (个体) express themselves in molecular processes (分子过程) and in personal health. They found that gene expression is   19  in chronically (长期地) lonely people. “We now have a new way for understanding the relationship   20   social experience and physical health,” explains the study’s lead author, Steve Cole of University of California, Los Angeles.
“This study—the first to link (联系)   21  with gene changes—is special and exciting,” says Emma Adam, a professor of human development at Northwestern University. “It   22  in the black box.”
According to John Cacioppo, an author of the study from the University of Chicago, the
work suggests that loneliness is a warning   23 , much like physical pain. “This feeling is so bad because   24  of us wants to be forgotten; that’ s also what human means,” he says. “It makes us   25  for other people and want to be with friends when we’re lonely.”

My name is Peter. I study in Cambell Middle School. It has a very large building. There are big playgrounds on two sides and a beautiful garden in front.
In the building, there is the headmaster’s room, the teacher’s rooms and thirty-four classrooms. We also have two labs（实验室） and a library in the building. Our library is on the ground floor. It has books almost （几乎）on all subjects. It opens after school from Monday to Friday.
Our school has uniforms（校服）. Boys wear white shirts and blue trousers. Girls wear white blouses and blue skirts. We all wear black shoes and white socks.
We study English, Maths, History, Biology, Music and PE at school. My favourite subject is Biology. I think it is fun. Our teachers are nice to us. They check（检查） our homework and help us when we need. I love my school and my teachers.
