Answer 1

First of all, use these as models:
Passive = The baseball was hit by John.
Active = John hit the baseball.
See the difference? They are saying the same thing, but with different word order and passive verbs.

I'll do the first two for you:
Henry is being eaten by the crocodile.
Henry has been eaten by the crocodile.

Now you try the rest, and then I'll check them over for you.

Answer 2

Make Henry the subject of the sentence. You do the first couple and repost, then I will make corrections if needed.
