【分析】
本题为英语语篇填空,需结合语境及语法规则确定每个空的正确形式:1. 考查过去时态,现在完成时语境中“科学家之前的想法”是过去动作,用think的过去式;2. 考查名词复数,astronaut是可数名词,此处指多名宇航员,用复数;3. 考查形容词最高级,表“最大的撞击坑”,定冠词后用big的最高级;4. 考查定冠词,独一无二的事物“月球”前加the;5. 考查连词,引导时间状语从句表“当……时”,用when;6. 考查介词,被动语态中表动作执行者用by;7. 考查主谓一致,主语this为第三人称单数,一般现在时用show的单三形式;8. 考查副词,修饰动词stayed用形容词quiet的副词形式;9. 考查非谓语动词,表目的用不定式;10. 考查物主代词,修饰名词side用it的形容词性物主代词。
【解析】
1. 结合语境,此处表示“科学家之前的想法”,对应过去的动作,故填thought;
2. astronaut为可数名词,此处指计划登陆的多名宇航员,故填复数形式astronauts;
3. 由定冠词the及语境“月球上最大的撞击坑”可知,用big的最高级biggest;
4. 独一无二的事物“月球”前需加定冠词the,故填the;
5. 此处引导时间状语从句,表“当小行星撞击月球时”,故填when;
6. 被动语态中表动作执行者用介词by,led by表示“由……领导”,故填by;
7. 主语this为第三人称单数,一般现在时中谓语动词用单三形式,故填shows;
8. 修饰动词stayed需用副词,形容词quiet的副词形式为quietly,故填quietly;
9. 此处表目的,用不定式作目的状语,故填to learn;
10. 修饰名词side需用形容词性物主代词,it的形容词性物主代词为its,故填its。
