    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.

    A few years ago, I went to China with my parents. The five-day trip left me with a deep impression.
    As the capital of China, Beijing is a very beautiful city with fresh air and clean streets which make the travelers feel very pleased. To my surprise, many people there were learning English. Later I was told that they did so because Beijing would hold the 29th Olympic Games and they wanted most foreigners to understand them. They strictly kept the traffic rules. When there was a red light, no one was seen crossing the street.
    Of all the places I visited, I liked the Summer Palace best. To our surprise, although it was winter when we were there, we still saw green trees and many fresh flowers. The whole park was very beautiful.
    We visited a very modern football field. We were told the buildings where the Olympic Games would be held were even better than that. I also enjoyed skiing in Xiangshan. Skiing is an interesting and exciting sport liked by many people.
    In my eyes, China is a nice place and Chinese people are very kind. In Beijing Station, there were so many people, and most of them were going home to spend the Spring Festival—the most important Chinese festival, with their families. Passengers helped each other carry luggage（行李）, and they were very kind to foreigners. We were given a card by the hotel we stayed at, on which was the address of the hotel. With the card we never got lost in the city.

    Do you think of white when someone talks about a polar bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find their food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2-3 babies at a time. They live with their mothers until they are about two-and-a-half years old.
    However, polar bears will die out soon because of people. There are only 20,000 to 25,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice— polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球气候变暖), pollution, hunting and so on.
    Ordinary people don't care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world. For me, I will not waiting. I will take the bus more often from now on.

    There are many wetlands in China and some of them are the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province, the east of China. They are homes for many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve is in them. More than 700 milu deer live freely there. There are not many red-crowned cranes in the world, but every winter you can see some in the Red-Crowned Cranes Nature Reserve in the Yellow Sea Wetlands.
    The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife.
