解答 41-45 DJGFB 46-49 AEIH
41．D．結合開頭一句They may be so small that they can crawl along the edge of a coin可知，這是描述蝸牛的體形比較小，所以選擇一個用來修飾形容詞比較級的副詞，從選項中DEI選擇，且表示極小的含義，故選D．
42．J．根據after引導的時間狀語從句a failed farming experiment almost wiped out its number in its native Pacific islands可知，此處是說蝸牛的數量面臨絕跡的命運，所以選擇名詞extinction；故選J．
43．G．這是描述的蝸牛的發(fā)展歷程，當這種蝸牛于1974年被引進這些島嶼時出現的狀況；be introduced to被引入某個地方．故選G．
44．F．這是挽救蝸牛的具體措施，將一部分投放到自然保護區(qū)，在他們能夠自理之前密切監(jiān)視著他們，故選F．
45．B．蝸牛管理員自然是很關系蝸牛的命運，成長過程，be concerned about sth關心某事；故選B．
46．A．野生動物保護區(qū)的動作人員說看到一個物種在自己面前消失感到難過，這是和蝸牛這一個物種相對比的；故選A．
47．E．這是描述若看到蝸牛也難逃這種滅絕命運時的難過傷心之情，所以用一個副詞來修飾形容詞sad；故選E．
48．I．此處需要一個用來修飾動詞短語called for的副詞，表示工作人員很嚴肅的呼吁承擔起相應的責任來保護這個物種；故選I．
49．H．文章最后提示事情的轉機，現在已經有人在行動挽救這個物種了，所以保護好環(huán)境是蝸牛生存的關鍵，所以用一個名詞來表示生存；故選H．
