题目内容
15.---Last year,Mary,a college student, to work for the UN.---How lucky she was!( )
| A. | is choosing | B. | is chosen | C. | was choosing | D. | was chosen |
分析 ---去年,一个大学生玛丽被选去为联合国工作.
---他多么幸运啊!
解答 答案:D,主语mary是动词choose的承受者,结合last year可知表达的是过去的事情用一般过去时的被动语态was/were+过去分词,主语三单,故was,choose的过去分词chosen,故答案是D.
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.
