1、 1、 现在完成时与一般过去时的区别一般过去时所表示的一个或一段过去时间，是可以具体确定的，与其他时间没有牵连。它所表示的事情纯属过去，与现在情况没有联系。注意： 一般过去式可以跟一段时间连用。一般过去式+for+一段时间，表示陈述过去事实，如he smoked for ten years,表示他过去吸了十年烟，言下之意是说现在肯定不吸了现在完成时表示的事情发生在不能具体指出的现在以前的过去某个或某段时间。它所表示的事情与现在情况有关系，是过去事情在现在产生的结果或对现在的影响。He has smoked for ten years,，首先我们得明白现在完成时的定义，表示1，过去事情对现在造成
