新概念英语第三册第11课,里的这句话是什么时态?all the things i had packed so carefully were soon in dreadful mess这句话是过去完成时吧,能不能把had改成has?为什么
网友回答
应该是过去式 i had packed so carefully 是定语从句,你删掉后再读读.
不能过去完成时,强调动作发生在过去的过去.all the things （i had packed so carefully ）were soon in dreadful mess,括号内为一个定语从句,pack发生在主句的were之前,过去的过去,因此从句用过去完成时had packed
