1#If you anticipated a class quiz, it would be best to study for it, because anticipation means you expected it. If you expect to have a quiz you should study for it.
2# If you’ve seen every movie and have an autograph of your favorite actor you are indeed devoted. Most people would only go to a few movies.
3# If you are enthralled by a book you would not put it down. Enthralled means obsessed, or lost in.
4# would you feel great elation when seeing your favorite band? I hope so. Elation is extreme happiness.
5# If you’re infatuated with the person next to you, you do not hate them, more like you have a passionate curiosity about them.
6# If you buy a cow impulsively, you did not think it out very well. You simply gave into your desire to buy a cow.
I hope this helps.
