过去完成时的问题
It had been wrapped up in newspaper and it contained half the money he had lost,together with a not which said:'A thief,yes,but only 50 per cent a thief!'
为什么用现在完成时?

Three months passed,and then one morning,Sam found his wallet outside his front door.It had been wrapped up in newspaper and it contained half the money he had lost,together with a note which said:'A thief,yes,but only 50 per cent a thief!'
整个句子是 一般过去时态,基于这个时态,早于这个时态发生的用完成时,即过去完成时
It had been wrapped up in newspaper
钱包寄过来的时候已经倍包在报纸里面 用过去完成时 没错啊
it contained half the money he had lost
已经丢失的钱 用过去完成时 也没错啊
钱包是用报纸包着的,里面有他丢失的钱的一半,而且还附着一张纸条,上面写着 :“一个小偷,是的,但只是一个50%的小偷!”
