题目内容
6.---Our classroom _______ every day.---So it is.It's our duty to keep it clean and tidy.( )
A. | cleans | B. | is cleaning | C. | is cleaned |
分析 --我们的教室每天都被打扫.
--是这样的.使它保持干净、整洁是我们的职责.
解答 答案:C 根据every day(每天),可知这是一般现在时态的标志,此处应用一般现在时.又知classroom(教室)是clean(打扫)这一动作的承受者,二者是被动关系,所此处应用一般现在时的被动语态,其结构为am/is/are+过去分词.又知classroom是单数名词,所以此处应用is cleaned.故选C.
点评 此题考查一般现在时的被动语态的用法.做题时,抓住句中标志词,先判断出时态;然后根据主语与动词的关系来判断语态,主语是动作的承受者就是被动语态.还要熟知各时态被动语态的结构.
