across from與from across的區別

1. across from 表靜態意義，意為“在對面”，與opposite同義，此時也可省略from只說across。如：

Just across from our house there’s a school. 就在我們房子的對面有一所學校。

I’m staying at a little hotel just across from the Libyan Embassy. 我住在利比亞大使館正對面的一所小旅館里。

2. from across則表動態意義，意為“從……的對面”。如：

He shouted to me from across the room. 他從房間的另一邊向我喊。

They waved at us from across the room. 他們從房間那一頭向我們招手。
