昨天我们参观了一个发电站(只说明昨天参观发电站这个事实)
2. 现在完成时中动作发生在过去某个或某段时间,它所表示的事情与现在情况有关系,是过去的事情对现在产生的结构或对现在的影响。
e.g: We have visited a power station.
昨天我们参观了一个发电站(说明现在对发现站有所了解)
用的时态 不同,表达的意思就不同
一般将来时
结构
will + 动词原形
am/is/are going to do
be to + 动词原形

be due to do sth.
will be 和be going to 的区别

2. be going to可指客观迹象表明马上要发生的事,will则表示说话者的观点、主观意识
表示按计划、安排将要做某事。
该结构还可表示命令、禁止或可能性等
表示即将发生的动作,不能和具体的时间状语连用。
