Answer 1

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．

解答 1．hopefully 考查副词．修饰介词短语for much longer用副词，名词hope的副词是hopefully．
2．named 考查过去分词．the Mars rover与name之间是动宾关系，用过去分词短语named Curiosity作定语修饰the Mars rover． 
3．if/whether 考查连词．根据句意：弄清楚现在或曾经是否有过生命．用连词if/whether．     
4．where 考查定语从句．分析句子结构可知这是一个定语从句，先行词place指地点，在从句中作状语，用关系副词where．
5．although/though/while 考查连词．根据句意：尽管"好奇号"只有三米长，一辆小汽车大小，但它装有许多有用的工具．用连词although/though/while．
6．its  考查代词．gun是名词，用形容词性物主代词作定语．         
7．a 考查冠词．a small amount of意为"少量"，是固定搭配．    
8．is made 考查动词时态和语态．be made up of意为"由…构成； 由…组成"，是固定搭配，因讲述的是一般事实，要用一般现在时态． 
9．With 考查介词．with the help of意为"在…的帮助下"，是固定搭配．
10．collecting 考查现在分词．it与collect之间是主谓关系，用现在分词短语collecting and studying rock and soil作伴随状语．
