If I (to see ) a ghost , I would scream .
( как только она придет ), you'll be under the spell of her fascination .
If I (to be ) you ,I would go in for sports .
I (to buy ) a pet for my son , if he takes good care of it .

If I saw a ghost, I would scream. As soon as she comes, you'll be under the spell of her fascination. If I were you, I would go in for sports. I will buy a pet for my son, if he takes good care of it.
