1. Concy IS at home. 2. Perfect! 3. I always leave my bookS at THE university. 4. (dal means from, right?) I return from the pub on foot. (or, I walk back from the pub) 5. My jacket IS at work. 6. I TAKE the train to GO to church. (It sounds better to say "go to church" than "arrive at church") 7. I (usually) walk to college (sounds more natural than "to go to college I walk") 8. I am two minutes from home. 9. I work from home. 10. I'm going to bed because I walked back from school. Hope this helps!
