10、报研究所”（SET1）的高级太空科学家萧斯塔克透露，由于新科技的帮助，科学家可望在未来25年内，在外太空找出其中一个星体上的生物。 该研究所自1984年成立以来，就开始监察无线电讯号，希望能探测到来自外太空发出的讯号。他们开展了著名的“凤凰计划”。到1999年中期，凤凰计划已观测了大约500颗星体，但始终没有地外文明信息被监测到。萧斯塔克说，“我们确实经常监测到信号，可经查实都是人类而不是外星人发出的，大部分是美国电话电报公司的。”萧斯塔克透露，研究所在赞助下将斥资2600万美元，研制一组射电望远镜阵。这组望远镜叫做“艾伦望远镜”。艾伦望远镜阵将覆盖1000到10000MHz的频率，预备在20
11、05年投入使用。该望远镜阵将建于旧金山市东北的哈特克里克气象台，可以全年不停地侦察附近10万甚至100万颗星体。萧斯塔克说，不能期望外星人与我们在电影中见到的相近，但推测他们也会有中央思维系统，眼睛、嘴巴和腿，也会繁殖，他们可能比人类聪明得多。,课外读物,alien,_The alien visited the Museum of Flight. _The alien bought a souvenir. _A UFO landed on Center Street. _The alien went into a store. _An alien got out of the UFO.,when,When,While,While,When the UFO took off the man was While the girl was,Bye,
