这个句子是有错的,正确的答案如下: They arrived at the top of the mountain. arrive at ,到达, on the top of ,在,的顶部,单独用作状语. 再问: 可将They arrined 和 on the top of the mountain分别单独看作一个整体吗?(arrive本身也是不及物呀!) 再答: 不能. 不及物动词要先变为及物动词短语才能 接宾语.所以先要有arrive at ,后面再接宾语the top of the mountain. 请看以下面的句子. On the top of the house, there is a flag.
