Can someone help me with journal response for Life of Pi by Yann Martel?

A journal response is a kind of reflection on something,
in this case a book. I am not sure how long of a journal response you are expected to
write, or whether you are expected to respond to the entire book or just a small section
of the book.  But generally, there is so much to say about a book, it is a good idea to
limit yourself to just one small aspect of the book. 

When
you do respond to one small aspect of the book, you are usually expected to state your
thoughts and feelings and to make connections between yourself and the book.  What did
the book make you think about? Is Pi like you in any way? Is he unlike you in any way? 
Is there an episode in the book that struck you as important in any
way?

A journal entry does not have to be as formal as an
essay, but it should have a little structure, I think.  For example, you should have
some sort of main idea stated in your entry and stick to the that point as you
write. 

If I were writing a journal entry on this book, I
might write about Pi's interesting approach to religion, his idea that it is fine to
have three different religions, all at the same time.  So I might start out a journal
entry with a sentence like this:

The idea that it is possible to have three
differerent religions, as Pi does,  is a useful idea in today's world, when we are so
divided by religion. 

Do you
see how I am setting the stage to reflect on just one particular aspect of the
book? 

Choose an aspect of the book that you have something
to say about, write a statement, and then keep going.  It is much easier than you
think!
