nobody has discoverd acure for cancer uptill now (yet)
maha is the most beautiful gril i have ever met (never)
it is ages since we last met (for)

I haven't ever met such a tall man
how long were you studied maths
the last time she cleaned the house was married ago
It is years since they last played together
pepole has not discoverd acure for cancer yet
maha is the most beautiful gril I have never met before
we have not met for ages
