    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.

    One evening last autumn, while Marcos Ugarte, 15, did his homework and his father, Eduardo, 47, prepared lesson plans, they heard screaming outside. It was from one of their neighbors, the Ma family. Then Marcos' eye was caught by a glow(火光) from there.

    "The house's on fire!" Marcos cried. Wearing only in shorts, the barefoot(光脚的) teen ran out with his dad. When they got there, Grandmother Yim Ma, mother Suzanne Ma, and son Nathan Ma were crying for help. Through the open front door, father Alex Ma was staggering(磕磕绊绊) down the stairs, coughing heavily.

    "Anyone else in it?" Eduardo asked.

    "My son!" Alex pointed to the second floor.

    Eduardo started up the stairs, but smoke and heat forced him to his knees. He crawled (爬) upstairs and down the hall where Alex said he would find Cody, 8, who had locked himself in a bedroom. Eduardo tried hard to open the door. But Cody made no reply, and Eduardo had to make his way back downstairs.  At the same time, Marcos saw Yim and Suzanne pulling a ladder, shouting: "Cody is at the window!"

    Marcos then placed the ladder near the window and climbed up. When Marcos reached the window, he pushed the screen into the room and managed to coax(哄) Cody out. Holding Cody with one arm, Marcos slowly climbed down the ladder. Cody was quickly sent to a nearby hospital, where he's treated for smoke inhalation(吸入).

    "You just don't see a teenager have that kind of braveness," said people around.
