    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.
