This isn't very difficult. As Ben says, your should try to get into the learning habit of trying to find things out for yourself. Check in a dictionary and then write three sentences to check whether you've understood the difference. Post them here and we'll be happy to tell you whether you're right or not. That's the way to learn. And while you're doing that, you could think about correcting your question. I'll give you a clue - the words 'different' and 'among' are wrong. Good luck.

What does your dictionary say? Try looking them up yourself first, to build up a good learning habit.
