求教英语题目：1:The room is big enough for us_____ A:to live B: living in C:to live in D: live in
2:_When will the train_____________? _In half an hour.
A:get B: reach C: arrive D: arrive in
第一题答案是C,第二题答案也是C.
请教问题：为什么live 与arrive 都是不及物动词,live要带in,而arrive却不要带in呢?

Answer 1

live 加 in是因为有明确的指出所要住的房子,而住在某处是LIVE IN
火车arrive并没有强调具体到达的某地,所以直接用就可以了
