题型：不详难度：来源：
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. |

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.
