I have known him for two years.为啥不对?
I knew him two years ago,过去式,只能说明,你在两年前是认识他的,或表达我在两年前就已经认识他了.
你们俩个到底什么时候初次认识对方的,这句话里没有表达清楚.
最常用地道的表达“我两年前（初次）认识他的”是：I got to know him two years ago."get to know"就有初次认识的意思了.或者用完成时,换一种方法说,我们是朋友已经两年了,We have been friends for two years.
“I met him two years ago.”跟I knew him two years ago类似,还是不对的.只能说明你两年前遇见他.不能说明你们什么时候最初认识.如果要用met,应该加上first,I first met him two years ago,就清楚的表达出我最初是两年前见到他的.
know 状态性动词,它后面可以跟表示时间延续的状语.
meet 终止性或点动词,它后面不可以跟表示时间延续的状语.
I have known him for two years.【正确】【原因是：know属于状态性动词】
I knew him two years ago.【错句】【原因是：你认识他就随时能够认识他,没有动作,比如你的同学肯定认识吧,不存在时间问题.所以改成下句就对了】
I met him two years ago.【正确】
I know him.我认识他.【正确】

I have known him for two years.【正确】【原因是：know属于状态性动词】
know 状态性动词,它后面可以跟表示时间延续的状语.
meet 终止性或点动词,它后面不可以跟表示时间延续的状语.
如果写成：I knew him two years ago.【错句】
【原因是：你认识他就随时能够认识他,没有动作,比如你的同学肯定认识吧,什么时候都一见如故.所以改成下句就对了】
I met him two years ago.【正确】
I know him.我认识他.【正确】
I knew him two years ago,过去式,只能说明,你在两年前是认识他的,或表达我在两年前就已经认识他了,但是外国人不这样说而习惯于说：I met him two years ago.
