The man standing behind the counter与The man who is standing behind the counter的比较

问题描述:

The man standing behind the counter与The man who is standing behind the counter的比较
为什么第一个句子不是is doing呢,如果说standing behind the counter是the man的后置定语,不是现在进行时,那为什么后面那个句子是who is而不是who呢?
额,新概念自学真坑爹,

两句句子意思完全一样.后一句who is standing behind the counter是一个定语从句,is standing是现在进行时.定语从句修饰the man.你疑惑的原因应该是不知道“动名词短语作定语”这种用法.前句的standing不是现在进行...
