I have lived here for more than twenty years.我住再次有二几十年了。
I have lived here since I was born. 我真想刚出生起就住再次有了。
I worked here for more than twenty years. (我现下不再在现在运转。)
I have worked here for many years.(现下我仍在现在运转。)
1)(对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(错) Harry has got married for six years. = Harry began to tet married six years ago, and is still tetting married now.
很明显，第二句不影响，它应换成 Harry got married six years ago. 或 Harry has been married for six years.
