—Why is the classroom so dirty?
—Sorry，sir. It yesterday, We forgot to do it.

A．doesn’t clean	B．didn’t clean
C．isn’t cleaned	D．wasn’t cleaned

答案

解析

试题分析：句意：教室为什么这么脏？——抱歉，老师。昨天没有打扫，我们忘记做了。结合语境可知下文描述的是过去的状态，故用一般过去时态，主语是动作对象，故用被动语态。选D。
点评：英语中的时态主要是借助于时间状语与上下文语境来进行判断。解答此类题型，首先要注意句子中的时间状语，如果没有则要通过分析上下文，结合语境来判断句子的时态。语态的判断主要是确定句子主语与谓语动词的关系。如果是主动关系则用主动语态，反之如果是动宾关系，则用被动语态。
