26、r. 21st Teens for Senior 3v Rahmun went to see Mini when he was released from prison:1）请注意第六段的He had pictured . He had imagined that. he had brought.这些句子的时态都用了过去完成时，说明在来之前Rahmun对他和Mini的重逢很憧憬，他原以为Mini还会跟他像小时候那样亲近，同时也暗示了接下来他内心将承受的失望之情。2）文章结尾的这句话：But to me the wedding feast was all the brighter for the thought that in a distant land a long-lost father met again with his child.释义：但是对我而言，一想到在遥远的地方一对失散已久的父女又能重聚了，我就觉得这个婚礼宴会更加绚丽。上文提到为了给Rahmun这笔钱，作者不得不节约婚礼的开支，省去用电灯和请军乐队的钱，所以此句中的“brighter”与上文的“give up the electric lights”互相照应。
