题目内容

20.对那个科学家的采访是昨天现场直播的吗?Was the interview with the scientist covered live yesterday?.

分析 Was the interview with the scientist covered live yesterday?

解答 答案:Was the interview with the scientist covered live yesterday?结合句意yesterday昨天表达的是过去的事情用一般过去时,主语the interview with the scientist 对那个科学家的采访,是动词cover的承受者,故用一般过去时的被动语态was/were+过去分词,live表示现场的,副词,主语三单,故was,提前构成一般疑问句,故答案是Was the interview with the scientist covered live yesterday?

点评 被动语态由"助动词be+及物动词的过去分词"构成.被动语态的时态变化只改变be的形式,过去分词部分不变.疑问式和否定式的变化也如此.
