一个英语句子的省略情况-----务必高手解答

我觉得,严格按照语法来说的话应该是which had been borrowed from the library。 因为确实是有前后时间关系的。关于过去完成时的用法,有一条是：在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。 e。g：I returned the book that I had borrowed。 我已归还了我借的书。 某高中课文里也有一句和这个类似：Some time later, Charoes Darnay found at a bank in London a letter from France addressed to him。 分析中说addressed to him是过去分词短语,作定语,相当于一个定语从句which had been addressed to him。 不过若是不严格说的话,说话时两个动作不强调前后关系,也可以都用一般过去时,则省略的是which were borrowed。都是可以的。
