题目内容
17.-How clean and tidy the room is!-Thanks.It ______ yesterday.( )
| A. | cleans | B. | cleaned | C. | is cleaned | D. | was cleaned |
分析 --房间好干净整洁啊!
--谢谢,昨天被打扫了.
解答 答案:D.考查被动语态.句意"--房间好干净整洁啊!--谢谢,昨天被打扫了.".A第三人称单数.B过去式.C一般现在时态的被动语态.D一般过去时态的被动语态.由yesterday昨天,可知,应该是一般过去时态,因此A,C不正确.主语it代指的是room房间,是动作clean的承受者,因此用一般过去时态的被动语态,结构是was/were+动词的过去分词.主语it单数,用was.clean的过去分词是cleaned.答案是D.
点评 被动语态表示主语是动作的承受者,被动语态由"be动词+及物动词的过去分词"构成,be动词的单复数要与主语的单复数保持一致,还要注意时态及过去分词的变法.
