题目内容
16.-Our classroom ____ every day.-So it is.It's our duty to keep it clean.( )
| A. | cleans | B. | is cleaning | C. | cleaned | D. | is cleaned |
分析 我们的教室每天被打扫.
是的,每天打扫.保持教室的干净是我们的责任.
解答 答案:D.根据IOur classroom ______every day可知主语Our classroom是动作clean的承受者,和动词clean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";根据句中的 every day可知,应该用一般现在时.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;Our classroom是第三人称单数,应用is.故选D.
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.
