this's This is* the part one of the sitting on the beach !!

It's the summer.  Welcome summer.  I am determined to go to the beach.  It is exciting and enjoyingable to be with my friends.  So I call my friends.  I'm passionate to swim and sitting under the warm sun.  We arrive at 7.00 am precisely.  We begin to extend^ on the beach; some go to the water and some sit on the beach.  On this beach which we usually go to, if you turn your head left and look there , you will see a cliff.  That's my favorite cliff.  I like to take my armchair` and go there to enjoy by the blue sky and white sand. and I usually see groups of geese and water birds.  It's an imaginiation imaginary picnic with the nature, so I begin to write my first paper of my book. This book I will name it, 'Memories on the Beach.'~

* "is" is not always contracted in writing

^ not sure this is the word you want to use

` I highly doubt you haul around an armchair.  Maybe a "lounge chair"
