【解析】

试题分析：本文属于说明文，介绍了the Mars rover在火星上进行科学研究的具体信息。

【1】hopefully 考查副词。在英语中副词通常做状语修饰形容词、副词或动词，本句中使用副词hopefully做状语修饰谓语部分。这个巨大的红色星球对我们所有人来说是一个谜，但是很有希望不会太久就可以解开这个谜了。

【2】named 考查分词做定语。本句中名词the Mars rover与动词name之间构成被动关系，所以使用过去分词短语在句做定语修饰名词the Mars rover。

【3】if/whether 考查宾语从句。本句中if/whether引导宾语从句作为动词短语find out的宾语，在句中不充当任何成分。

【4】where考查定语从句。本题定语从句的先行词是the place，定语从句动词land是不及物动词，后面不需要直接接宾语，句子结构很完整，所以使用关系副词where引导定语从句，在句中做状语。

【5】although/though/while 考查连词。尽管这些工具只有三米长，大约是一辆汽车大小，但Curiosity使用了很多这样的工具。上下文之间是转折关系，所以使用although/though/while引导。

【6】its考查所有格。本句中横线有名词短语own laser gun，所以使用所有格its修饰。

【7】a 考查固定搭配。短语an amount of许多，amount前面有形容词small修饰，所以在small前面加a。激光枪把很多岩石变成气体。

【8】is made 考查固定搭配。固定短语be made up of由...组成；Curiosity能够研究岩石由什么组成的。

【9】With考查介词短语。短语with the help of在...的帮助下；在这些工具的帮助下，Curiosity将作为一个机器地理专家。

【10】collecting 考查分词做状语。动词collect与句子主语it构成主动关系，所以使用现在分词collecting在句中做状语。
