讲现在完成时的时候要把瞬间动词转化成延续性动词,为什么?

因为现在完成时中有一种用法:表示过去(延续性)动作或状态持续至今,也可能持续下去。
其实,不管什么时态,就是要强调瞬间动词不能与一段时间连用。瞬间动词:一发生就结束。
典型的瞬间动词:(来自百度百科:close, leave, buy, join, become, begin, fall,fall ill,get to(know), come, go, see, hear, hear from, catch a cold, kill)
例子:
He has come.他来了(正确,因为没有时间状语)
He has come for two minutes.(错误:come不能与for two minutes连用)
He has been here for two minutes.(正确,状语与for two minutes连用)
否定句不在此列。(因为否定就意味着没发生这个动作)
I have not seen him for two years.
