could some one tell me why?

[danielkramer]

i would like to know why the following sentence should be used with Present Perfect?

Linda has lost her passport again, It`s the second time this has happened (not happens)


thanks
Daniel

Tense should be kept consistent: has lost; has happened.

Thank you,

is that the only reason. I have a grammar book that says: Note that we say "it`s the first time something happens"


does this mean, its the first time we say something?

Thanks again
Daniel

It's the first time is usually followed by the present perfect.
