介词 across 用法详解
1. 无论用作介词还是用作副词,均可表示动态意义或静态意义:
(1) 表示动态意义,意为“横过”“到…的另一边”。如:
Can you swim across? 你能游过去吗? (副词用法)
I cam swim across the river in 10 minutes. 我可以在10分钟之内游过河去。(介词用法)
(2) 表示静态意义,意为“在…的另一边”。如:
My house is just across the street. 我家就在街道对面。(介词用法)
We leave Dover at ten and we should be across in France by midnight. 我们10点钟离开多佛,午夜时应能抵达法国那边。(副词用法)
2. across from与from across都可以说,但含义稍有区别:
(1) across from 表静态意义,意为“在对面”,与opposite同义,此时也可省略from只说across。如:
Just across from our house there’s a school. 就在我们房子的对面有一所学校。
I’m staying at a little hotel just across from the Libyan Embassy. 我住在利比亚大使馆正对面的一所小旅馆里。
(2) from across 则表动态意义,意为“从……的对面”。如:
He shouted to me from across the room. 他从房间的另一边向我喊。
They waved at us from across the room. 他们从房间那一头向我们招手。
3. 注意不要与动词cross弄混(www.hxen.net):
(1) 表示“穿过”时的用法比较:
It’s dangerous for an old man to cross such a crowded street. 老人穿过这样拥挤的街道很危险。
It’s dangerous for an old man to walk across such a crowded street. 老人穿过这样拥挤的街道很危险。
(2) 表示“交叉”时的用法比较:
