2.The tiger is now in danger of disappearing.So more attention ____ to protecting the tiger.( )| A. | paid | B. | must pay | C. | was paid | D. | must be paid |
分析 翻译:老虎正面临灭绝的危险.所以必须更多关注去保护老虎.
解答 答案:D.根据句意,老虎现在有消失的危险,所以必须更多关注保护老虎,attention是动词paid的动作承受者,表示被关注,因此空应用被动语态;由于老虎现在有消失的危险,所以必须更多关注保护老虎,用must,含有情态动词的被动语态的基本结构是情态动词+be+动词的过去分词;故选D.
点评 本题考查的是情态动词的被动语态,其构成是情态动词(should/can/must/may/could等)+be+及物动词的过去分词.
