Today is 12 April 2061, the 50th International Day of Human Space Flight. I want to share the story of my brother Leo. In the year 2050, humans finally built a spaceship which was fast enough to travel to distant planets. 16-year-old Leo was chosen to join the first team to visit Planet Zora, a small planet 50 light years from the Earth. Scientists said Zora had air and water, so it might be a perfect new home for humans. After a 3-month trip through space, Leo and his team landed on Zora. The planet was covered with green forests and blue lakes, just like the Earth. But there were no animals or people—only strange, tall flowers that glowed at night. One day, Leo spotted a small, round stone with a shining mark on it. When he touched the stone, a soft voice spoke，“Welcome, friends from the Earth. We have been waiting for you.” It was the voice of a group of aliens. They said they had watched the Earth for many years and wanted to be friends with humans. The aliens showed Leo how to grow plants and how to make air cleaner and food tastier. Before Leo left, they gave him a bag of glowing flower seeds as a gift. When Leo returned to the Earth, he told everyone about Zora. The flower seeds grew well on Earth, and soon the skies in many cities turned bluer. People started to call Zora “the planet of hope”, and Leo became a hero because he brought peace and new life to his homeland. ( )1. How far was Planet Zora from the Earth? A. 3 light years. B. 16 light years. C. 50 light years. D. 500 light years. ( )2. What did Leo's team NOT find when they landed on Planet Zora? A. Forests. B. Lakes. C. Animals. D. Flowers. C C ( )3. What does the underlined word “spotted” in Paragraph 3 mean? A. Found. B. Bought. C. Sold. D. Imagined. ( )4. What did Leo learn from the aliens? A. How to grow plants. B. How to make air cleaner. C. How to make food tastier. D. All of the above. A D ( )5. What might the text come from? A. A news report. B. An ad. C. A science fiction novel. D. A sports magazine.
