Ender Wiggin is a 6-year-old army general(将军), and a gaming genius（天才). Sometime in Earth's future, humans will have a war with bug-like alien species, the "Buggers". They use computers to control battles(战争).To prepare for the war, all talented children study in a special school to become generals. Wiggin is one of them.

    Students play games to practise their commanding (指挥的) skills. Wiggin is the best of them. At last, Wiggin comes to his final test. The fleet(舰队) he commands in the game is the real human army. Wiggin is actually "playing" the final battle between humans and Buggers. Will he win? What will happen to humans after the battle? Let's find out in the book Ender's Game, by the American writer Orson Scott Card.

    One of the most detailed(详细的) descriptions Of a UEO was given by nine-year-old Gaynor in Sunderland in July 1976.

    Gaynor lived in Oakenholt, a village in North Wales. On her way home from school, she saw a silver(银色的) object shaped like a saucer(茶碟) in a field not far from her home.

    The strange craft(飞行物) was about 30 feet long and 9 feet high. It had yellow windows along the side and on the top there was a light flashing in a kind of box. Although Gaynor was very frightened, she did not run away. Instead, she lay quietly in the long grass and watched the door of the strange craft open. She saw two people wearing silver suits come out of the craft. They were carrying some kind of equipment(设备) which they used to examine the ground.  They were short and had large pink eyes, Gaynor reported.

    After about half an hour, the two people went back into the craft. At once there was a loud noise and the UFO took off.

    Although Gaynor told her mother what she had seen, her family decided to keep quiet about it. They did not want people to laugh at their daughter. However, 18 months later, Gaynor told her story to UFO experts. They hypnotized(使进入睡眠状态) Gaynor so that they could be sure she was telling the truth.

    Not only did she repeat her story, but also she was able to draw a picture of what she had seen!

    Do you believe there are aliens? Well, make a phone call and you will know. A group of Americans can help. They make a device to "talk" to aliens. If you want to talk to an alien, you only need to visit www.TalkToAliens.com, call 1-900-266-0300 and say, "Hello aliens. This is Earth calling. Can you hear me?" You can say anything you want.

    But now they only take phone calls from people in the US. The call is $3.99 every minute. After the hotline began in February, www.TalkToAliens.com has got hundreds of calls. There is one call every three minutes. They are also trying to send people's emails, photos or videos into space.
