saw some trees leaves of which were black wth disease
here is the pen you lost it yesterday
the girl told me the news is not here now
this is the village where my father worked in three years ago
the reason why he gave us sounded a little strange
here is the only one of the students who knows French
i will never forget the day on which i spent with you
which was planned,we met at the railway station
this is the teacher with whom we have learnt a lot
is this farm we visited last year?
