题目内容
2.Rodger knows her very well.They by an old friend ten years ago.( )| A. | were introduced | B. | introduced | C. | are introduced | D. | introduces |
分析 Rodger很了解她.他们是十年前由一位老朋友介绍认识的.
解答 答案是A.考查被动语态,他们之间是由朋友介绍认识,由此可见they与动词introduce之间是被动关系,又因为时间状语是ten years ago,所以用一般过去时的被动语态,故答案选A.
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.掌握各种时态的被动语态是解题的关键.
