I saw you two up at his place ; it's just a truck up on the highway

问题描述:

I saw you two up at his place ; it's just a truck up on the highway

up at his place:就是在他家的意思 后面的up on the highway 也是在高速公路的意思
作副词 我看见你在他的地方,它只是一辆卡车在公路上
I saw you in his place,it's just a truck on the highway
这句话也是对的是的,我就是不明白,那up具体是用来强调什么还是其他什么?我也不清楚额
