题目内容
19.Keys used for the doors.( )| A. | is; opening | B. | is; opened | C. | are; opening | D. | are; opened |
分析 钥匙被用来开门.
解答 答案:C.根据题干的主语keys"钥匙"和动作use"使用"可知,主语是动作的承受者,和动词use构成被动的关系,应该用被动语态.被动语态的结构是"be+过去分词";根据句意可知,本句是强调的现在存在的事实情况,应用一般现在时.一般现在时态的被动语态的构成:am/is/are+及物动词的过去分词;keys是名词复数,应用are.又根据for是介词,后面应跟动名词可知,应用opening.故选C.
点评 主要考查被动语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是一般现在时态的被动语态.一定要注意:一般现在时态的被动语态的构成:am/is/are+及物动词的过去分词,以及动词过去分词的形式.
