答案与解析
【语篇导读】本文是一篇说明文。文章介绍了嫦娥四号无人探测器在月球背面成功着陆,彰显了中国成为第一个使探测器在月球背面着陆的国家的民族自豪感。
1.touched 考查动词的时态。分析句子成分可知,主语为The unmanned Chang’e-4 probe,设空处为谓语动词,根据空后的last week可知,此处应用一般过去时。
2.extremely 考查副词。此处修饰形容词challenging,应用副词形式。
3.where 考查定语从句。先行词是一个表示地点的名词spot,并且引导词在从句中充当地点状语,故用关系副词where。
4.interest 考查名词。“be+of+抽象名词”为固定搭配。
5.than 考查介词。前面的more是提示,构成比较结构。
6.to find 考查非谓语动词。分析句子成分可知,这里用不定式短语做目的状语。
7.means 考查动词的时态。根据上文的时态可知此处应用一般现在时,这里用it做主语,故用mean的第三人称单数形式。
8.is constructed 考查动词的时态和语态。分析句子结构可知,moon与动词construct之间是逻辑上的动宾关系,故用被动语态。
9.much 考查形容词。设空处后面的ice是不可数名词,故用much修饰。
10.its 考查代词。由后面的名词plans可知,此处应使用形容词性物主代词。故用its。
