I've arrived by train为什么不是I arrived by train?
话说过去时是过去的动作,和现在无关,而此句来自新概念2,lesson2,“她到了”,这个也是和现在没有关联了啊,为什么这个用的是have arrived?
这两种都可以用吗?越清晰越被采纳!
不要用语法解释语法的答案，老外解释语法肯定不会用这么生硬的解释，我要两者在什么感觉上、在具体不同场景上用哪一种，不要什么语法，那害死中国成片成片新旧高学历英语哑巴了

都可以.
前者I've=I have,表示现在完成时.
后者表示一般过去时.
I've arrived by train.我已经乘火车到达这里
I arrived by train.我是乘火车到达这里的.
问：Are you there?
I've arrived there by train.
问：How did you get there?
I arrived there by train.

I've arrived by train为什么不是I arrived by train? ‘I’ve just arrived by train中的这两句英语的区别?I arrived by train.I've arrived by train. 这句句子语法对吗I've arrived by train a moment ago. I arrived by train a moment ago.的同义句 i have just arrived by train.为什么有have.它起什么作用 I have just arrived by train这里为什么要用现在完成时呢 i have arrived by train中的arrive 为什么用完成?而不用be there? 英语句子结构改写：I arrived by train a moment ago. ‘I have just arrived by train,’she said.变成间接引语表状态情绪感觉精神活动的动词,不用现在完成时对吗～I have just arrived by train 这句话对吗 i want to take a train to Beijing 为什么是take a train 不是by trai
