cross 和 across 的区别

cross是动词，接宾语；across是介词，在动词后面，如go across .

cross 是及物动词, 是越过, 渡过的意思　We crossed the street.　我们穿过马路　We crossed the river by boat.　我们搭船渡过小河　　He is crossing the street now.　他正在穿越马路　across 是介系词 或 副词, 虽然也是穿越, 但没说如何穿越　　We walked across the street.　我们(走)穿过马路　这句话跟上面不同的地方, 是 across 本身不是动词所以要加上动词 - walked across 来形容走穿越的意思　　We rowed accross the river in a boat.　我们划著小船过河　　He is walking across the street now.　他正在（走著）穿越马路　所以最简单的记法就是across 一定要加上动词
