Prepositional Phrase

I am a student from Mexico to the US and my teacher is showing me prepositional phrases. She says to unscramble these sentence parts and write them punctually correct. Help?

1.
and neither knew
for the fifteen years
Danny and I lived
of our lives
within five blocks of each other
of the other's existence

2.
I could see the doctor
over Dean's shoulder
with his black bag
between his feet
against the wall

3.
in one of Colin's books
with the ivy behind her
of Colin's books
she was
and with her nice fresh face smiling across the greenery
with the sunlight through the trees
dappling her long blue cloak
like a softly colored illustration

Thank you

Danny and I lived

I don't feel like doing the rest. These sentences suck and no one would write anything like this in English.

Do your own homework. You might learn something.

These sentences come from Richard Bach, in "Johnathan Livingston Seagull", Chaim Potok in "The Chosen", and Stephen King's "Coffey on the Mile".

Fucking horrible exercises.
This is how they teach you English in Mexico? No wonder you all speak it so badly. Sorry :(

I think your #2 is ambiguous and could be written better. The placement of "over Dean's shoulder" in your version makes it confusing as to whether the wall or the doctor is over Dean's shoulder. THis is likely what the purpose of the exercise is--to learn how to group prepositional phrases to avoid ambiguity.
