【语篇解读】本文是记叙文,主要描述了不同国家探索火星的方法。
1.disappeared 考查时态。句意:由于有害的辐射,大部分液态水消失了。根据前文的时间 “About 4 billion years ago”可知,此处是描述过去发生的事情,需要用一般过去时。故填disappeared。
2.it 考查代词。句意:但是有些液态水仍然在地下。根据句意,此处指代前文的“liquid water”,water是不可数名词,需要用单数it来指代。故填it。
3.for 考查介词。句意:中国的“天问一号”任务将通过固定在月球车上的雷达来寻找现有的水。search for表示“寻找”,是固定搭配。故填for。
4.using 考查现在分词。句意:欧洲航天局的航天器利用来自太空的雷达发现了地表水存在的证据。此处前后句没有连接词,且后半句没有主语,所以use是非谓语动词,use和逻辑主语 “The European Space Agency’s spacecraft”之间是主动关系,需要用现在分词表示主动。故填using。
5.valuable 考查形容词。句意:天问一号还将为中国提供宝贵的火星经验,并为计划于本世纪20年代末进行的样本返回任务奠定基础。此处需要用形容词做定语,修饰名词experience。故填valuable。
6.the 考查冠词。句意同上题。the end of…表示“在……末”,是固定搭配。故填the。
7.made 考查过去分词。句意:尽管在航天器上放置科学仪器方面取得了令人印象深刻的进步,但只有地球上能够准确测试样本的技术,才能验证样本中是否存在生命。此make与逻辑后主语语advances是被动关系,故此处用过去分词做后置定语,修饰名词advances。故填made。
8.which 考查定语从句。句意同上题。本句是定语从句,从句修饰名词 technology, technology是物,在从句中做主语,且本句是非限制性定语从句,关系词不能用that。故填which。
9.successfully 考查副词。句意:截至2020年,只有美国国家航空航天局(NASA)在火星上成功着陆并操作了航天器。此处需要副词来修饰动词land和operate。故填successfully。
10.opportunities 考查名词复数。句意:更多的国家探索火星意味着更多的全球合作机会。根据前文的 “More countries”可知,此处机会应该用复数,和前文对应。故填opportunities。
