That sounds like a letter to reviewer for your writing portfolio. What they want you to do is write a paper in the form of a letter that speaks directly to a person who will read the rest of your portfolio and tell them about how you have grown as a writer over your lifetime, tell them what you have learned, if you read more now, what you enjoy about it, how you got turned on to reading, experiences with reading outside of school, how reading and writing will help you out in the future whether it be in your job or in your personal life, the impact that being able to write and read could have on your future/life, how your writing may effect others in some way [good to discuss feature articles/editorials there because it could have presented information and changed someone's opinion on an issue], how good of a writer that you hope to be and then in closing reference your opening about how you have grown and how writing the portfolio and etc. has been.

Good luck. Hope this helps.
