| Do you believe there are aliens (外星人)? Well, make a phone call and you will know. A group of Americans can help. They made a device (装置) to "talk" to aliens. If you want to talk to an alien, you only need to visit www. Talk To Aliens. com, call l-900-226-0300 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. Talk To Aliens. com has got hundreds of calls. There is one call every three minutes. They are also trying to send people's e-mails, photos and videos into space. | ||||
