I made a few changes, the really important changes are in * *. Number 1 is perfect **i read this too quickly, the comment above is correct For number 2, you want to change some things. it should be "I *ran* into Kislov on the way to work yesterday morning and we had a small conversation, he caught me up on all the gossip about the university" Technically, you want to say "so i could catch up" if it was a planned meeting. But if you just ran into him, then you want to say "he caught me up." Number 3 is good. Number 4 is good. Number 5 is good. Number 6 is good. Number seven should be "I don't think that someone *can benefit* from watching TV"
