    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. Join me and save the polar bears, and, of course, the tigers, the giant pandas and...

Anyone can add or change the information if he or she finds it not correct or not well written.

    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.
    小题1:When did Captain James Cook travel around Antarctica?
    A．In the 1670s.B．In the 1760s.C．In the 1770s.D．In the 1780s.
