题目内容

Excuse me. I _________ I was blocking(挡) your way.
A．didn't realizeB．don't realizeC．haven't realizedD．wasn't realizing
A

试题分析：句意:打扰了,我不知道我挡了你的路.结合语境可知本句描述的是刚才发生的动作,故用一般过去时态.realize是我的主动动作,故不用被动语态,选A.
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，尤其要注意一些特殊动词的用法。
