课文概述
文章讲述了由于一个愚蠢的错误导致再无外星人光顾地球的故事。
故事开始介绍了爱达荷州温加尔奇的治安官巴特·卡默伦的性格,他是一个脾气暴躁,没有耐心的人。
在1956年4月14日那个特殊的一天,作者亲眼目睹了飞碟。
但仅仅因为外星人过于正式的英语和巴特那天过于糟糕的心情,使得巴特·卡默伦对外星人一而再、再而三地误解。
最终外星人飞回了金星。
正因为此,再也没有来自外星的访问者。

金星也叫常庚星或昏星,也有人叫它启明星或晨星。
金星是太空中除太阳和月亮以外最亮的星体,沿着离太阳约一亿六百万公里的椭圆轨道运行,运行一周约需225天。
金星表面的平均温度约475oC,其中约95%的大气是二氧化碳。
金星上几乎没有氧气。
这使得金星上几乎不可能有我们所知的生命。
除金星和地球外,太阳还有七个行星,它们是:
水星(theMercury),火星(theMars),木星(theJupiter),土星(theSaturn),天王星(theUranus),海王星(theNeptune和冥王星(thePluto)。
