the mind which is forgotten which 是定语从句的关系代词,指代现行词的mind,在从句is forgotten 中做主语要省略,就连同主语谓语一起省略,因此,the mind which is forgotten =the mind forgotten 再类比一个过去分词...This is the pen which was given by my friend. 意思是：这支笔被我朋友送掉了，翻译对吗？还是：笔送我朋友了这是我朋友送我的笔是不是可以看做This is the pen given by my friend. 主语是笔吧，翻译起来“我”在哪里啊？这么看，这是一支笔，一支什么笔呢？given by my friend，我朋友给的= this is a pen ( which is ) given by my friend=this is a pen+the pen is given by my friend 并起来，就是，这是一支我朋友送的笔至于“我”这因为是语境问题，类似于祈使句，再双方都知道对方是谁的时候用
