(答案→)be of benefit
解析：
【小题1】be of benefit 本题考察“of+名词”=该名词转换成的形容词。of benefit= beneficial.有益的。
【小题2】 in other words 本句是两个同位语短语的转换that is to say=in other words换句话说。
【小题3】 junior to 本句中的be junior to比…年轻；换原句的three years younger than me
【小题4】 ahead of 本句使用ahead of代替前句的in front of，都表示在…之前。
【小题5】.all in all 这两个短语都表示共计，总共。
【小题6】his/him accepting 本句使用动名词的复合结构，imagine one’s/one doing sth想象某人做某事。
