    Are you a big fan of E.T. (Extraterrestrial) or aliens? Then you should read Extraterrestrial Civilizations (《地球以外的文明世界》) by American writer Isaac Asimov (1920-1992). In his 1979 book, Asimov looked at whether there is life beyond the Earth. He also talked about how we might be able tocommunicate with aliens someday. Asimov even told us that there are possibly about 500,000 civilizations (文明) in the galaxy (银河系). The book may be a little out of fashion since it came out in the 70s. But you'll still enjoy the good reasoning (推理) and imagination of it. Asimov was a science fiction (科幻故事) master. His most famous works talk about the relationship between robots and humankind.

    John James Audubon loved all kinds of birds. He spent his life studying them. He painted all the birds of North America.

    John James Audubon was born in Haiti in 1785. When he was a young boy, he moved to France with his family. His father was in the French Navy. He had a farm in the United States. When John was 18, his father sent him to the farm, hoping John would take care of it. But John didn't want to do that. He wanted to hunt, fish, and draw birds. John drew lots of pictures of birds. He wanted to make them look real.

    In 1808, John married Lucy Bakewell and they moved to Kentucky. John and a friend went into business there. They ran a shop. John really didn't like working in the shop. The business soon failed. John wanted to paint full-time. Lucy agreed to help. She got a teaching job to support the family. By that time, they had two young sons.

    John wanted his bird paintings made into a book. He finally did find someone to print his bird pictures in a book. Many people wanted John Audubon's book. Although his book was a great success, John wasn't happy with it. He wanted to show every bird found in North America. By 1838, John finished a great work. It wasn't just one book. It was an amazing set of four books called The Birds of America. It had many paintings. Today, these paintings are very famous.
