What about the rest of you?” “It’s very cold there,” answered Kim. “And it’s super windy on Mars,” added Lucy. “I know,” said Tommy. “But we can ask RK-5 to take us to the Mars of the future. I’m sure that humans will find a way to live safely on Mars.” Tommy pulled his little friend from his jacket pocket and asked, “RK-5, do you know anything about Mars?” “of course,”replied RK-5. “A year on Mars is 687 Earth days. A day is 24 hours and 40 minutes. The atmosphere on Mars is…” “Stop!” said Tommy. “Will humans settle on Mars?” “Humans will be living on Mars 250 years from now.” The friends smiled and decided that they would go to Mars. Tommy and his friends were on their way to Mars. When Tommy opened his eyes, he saw a rocky area covered with red dust(尘土). Tommy spotted a cave.” In the darkness of the cave, Tommy turned on RK-5’s lights. “Look!” said Jack.. They were all shocked to see something like a person. “What is it?” asked Sam. “It’s a Martian,” answered RK-5. The Martian was trembling(发抖) with fear. “Please don't be afraid of us,” said Tommy. “We will not hurt you.” “You may not mean to hurt me,” he said, “but most of the people of Mars have died since the Earthings came here. Your people have brought sickness to Mars. There are very few of us left.” “We would like to help your people,” said Tommy. “What can we do?” “Make the Earthings go away,” said the little Martian. Tommy sat down on the floor of the cave. He was quiet. He was trying to think of a way to help the Martian. —5— 豆丁致力于构建全球领先的文档发布与销售平台，面向世界范围提供便捷、安全、专业、有效的文档营销服务。 包括中国、日本、韩国、北美、欧洲等在内的豆丁全球分站，将面向全球各地的文档拥有者和代理商提供服务， 帮助他们把文档发行到世界的每一个角落。豆丁正在全球各地建立便捷、安全、高效的支付与兑换渠道，为每一 位用户提供优质的文档交易和账务服务。 —6—
