【分析】
这是一篇说明文。文章讲述了哈雷彗星命名的由来。
1. 考查可数名词的数。句意:彗星是宇宙中最美丽、最有趣的景观之一。根据前文 “among the most beautiful and interesting” 可知,此处指众多有趣景观之一,所以空处名词需用复数。故填 sights 。
2. 考查时态。句意:几个世纪以来,人们对研究它们表现出极大的兴趣。根据时间状语 For centuries 可知,空处谓语动词需用现在完成时态或现在完成进行时态,表示过去发生的动作一直持续到现在将会继续下去,主语是复数 people ,所以助动词需用 have 。故填 have shown/have been showing 。
3. 考查连词。句意:根据他的计算,哈雷预测这颗明亮的彗星将在 1758 年或 1759 年回归 —— 这距离他第一次看到这颗彗星大约 75 年。根据前一句 “ In 1682, Edmund Halley, an astronomer, noticed a comet that was especially bright and large. (1682 年,天文学家埃德蒙 · 哈雷注意到一颗特别明亮和巨大的彗星。 )” 可知,哈雷第一次看到那颗彗星是 1682 年,再次看到可能是 1758 年或 1759 年,此处表示 75 年后,所以需用连词 after 。故填 after 。
