I have just arrived by train这里为什么要用现在完成时呢

一个现在完成时态,再加上一个副词just表示“刚刚” 很好地说明了我现在的一种状态,我坐火车刚刚到.

'I have just arrived by train,'she said.变成间接引语

yes, she just arrived by train.请采纳谢谢

i have just arrived by train. 为什么有have.它起什么作用 谢谢

中文意思是 :我已经乘火车到了.have+过去分词 是现在完成时的结构.这里 have arrived 是已经到达了的意思.

i have arrived by train为什么用现在完成时

从句中用的是现在完成时代替将来完成时,强调完成,主句中仍然要用将来时

I've just arrived by train.

现在完全时:have( has) +动词过去式.表示现在业已完成的动作

I've arrived by train为什么不是I arrived by train?

by 表示通过什么交通工具(indicating a means of transport or a route taken 表示运输或取道的方式): travel by boat/bus/car/plane 乘船[公共汽车/小汽车/飞机]旅行 * travel by air/land/sea 航空[陆路/航海]旅行.

跪求I've just arrive by train.的意思

首先,原句打得有点问题——应该是:I've just 【arrived】 by train.【I've=I have】句子所用时态:【现在完成时】句意:我已经乘火车到达了. 祝你进步,时时开心!O(∩_∩)O~~

just的意义及用法?

形容词:公正的;副词:刚好地,正好地

i have just arrived by train 这句是现在完成时吧!?

i have just arrived by train.意思:我刚刚乘火车到达.可以看到have是现在时 ,而arrived是过去式.所以是现在完成时.have是现在的状态,arrived是完成的事情.

I've - just - arrived - by - train是什么意思

我已经坐火车到达了.I've就是I have,完成时,应翻译成已经
