Answer 1

分析 本文屬于說明文，介紹了the Mars rover在火星上進行科學研究的具體信息．

解答 1．hopefully 考查副詞．修飾介詞短語for much longer用副詞，名詞hope的副詞是hopefully．
2．named 考查過去分詞．the Mars rover與name之間是動賓關系，用過去分詞短語named Curiosity作定語修飾the Mars rover． 
3．if/whether 考查連詞．根據句意：弄清楚現在或曾經是否有過生命．用連詞if/whether．     
4．where 考查定語從句．分析句子結構可知這是一個定語從句，先行詞place指地點，在從句中作狀語，用關系副詞where．
5．although/though/while 考查連詞．根據句意：盡管"好奇號"只有三米長，一輛小汽車大小，但它裝有許多有用的工具．用連詞although/though/while．
6．its  考查代詞．gun是名詞，用形容詞性物主代詞作定語．         
7．a 考查冠詞．a small amount of意為"少量"，是固定搭配．    
8．is made 考查動詞時態(tài)和語態(tài)．be made up of意為"由…構成； 由…組成"，是固定搭配，因講述的是一般事實，要用一般現在時態(tài)． 
9．With 考查介詞．with the help of意為"在…的幫助下"，是固定搭配．
10．collecting 考查現在分詞．it與collect之間是主謂關系，用現在分詞短語collecting and studying rock and soil作伴隨狀語．

點評 在一篇200詞左右的語篇（短文或對話）中留出10處空白，部分空白的后面給出單詞的基本形式，要求考生根據上下文填寫空白處所需的內容或所提供單詞的正確形式，所填寫詞語不得多于3個單詞．要做好語法填空題，理解短文是解題的前提，扎實的詞匯、句型和語法知識是基礎，英語國家的背景知識是必要的補充．考生須靈活運用語法知識，如單詞詞性、單詞時態(tài)、名詞單復數、連接詞、代詞、冠詞等判斷各空白處應填寫的內容．答完后，還要通讀全文，核對所填單詞形式是否正確，是否符合語境．
