Some of them have ice and snow. It’s not easy for animals and plants to live in cold deserts. But there is life! For example, polar bears, seals and penguins can live there. Some scientists like to study life in deserts because some conditions (情况) there are like those on Mars. Life in a cold desert is not easy. In winter, it is dark for a long time. The wind is strong, and the weather is very cold. But these cold deserts are beautiful, too. In summer, the sun shines (照射) for a very long time. In winter, you can sometimes see dancing lights in the sky. They can be green, purple, pink or blue. They make the cold desert look like a dream.
