题目内容
18.______ into use in April 2000,the hotline was meant for residents reporting water and heating supply breakdowns.( )A. | Put | B. | Putting | C. | To put | D. | Being put |
分析 2000年四月被投入使用,这个热线意在让居民报告水和供热系统的故障.
解答 答案是C.本题考查分词做状语.分词做状语时分词的选择是看分词和句子主语之间的关系:分词和句子主语之间是主谓关系(主动关系),用现在分词;分词和句子主语之间是动宾关系(被动关系),用过去分词;题干中put和主语the hotline之间是被动关系,所以过去分词,答案选择A.;动词不定式放在句首往往表示目的,不符合句意;现在分词一般式的被动语态表示被动和进行的动作,本题显然表示的是动作的完成,排除D.
点评 在非谓语动词的解题中要在掌握其基本用法的基础上关注并积累一些固定用法,结合具体语境做出合理的判断.
