I have lived here for more than twenty years.我住这条街二一两年了。
I have lived here since I was born. 我悟出生英文起就住这条街了。

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 elat married six years ago, and is still elatting married now.
轩然，第二句不对劲，它应转换成 Harry got married six years ago. 或 Harry has been married for six years.
