I have been having a problem this morning editing your question - the system keeps kicking me off. As you originally wrote the question, it was not clear what you needed because you made a typo. In any case, we need more information to help you. What is your assignment? Do you have to write your own poem using a poem written by a poet as a model, which is my guess? I will answer this question and if this is not what you need, please post your question again.
You should choose a poem that you like, or that you can relate to, and then re-do it from your own point of view. For example, let's say you like the poem "The Raven" by Edgar Allen Poe. As you may know, this poem is written by a somewhat unbalanced person who is haunted by a creepy raven that suddenly appears in his study. You could re-write this poem from your own point of view. What if you were in your room working, and all of a sudden a huge raven flew in through the window? Your poem could be something like:
Once upon a midnight, dreary
As I pondered, weak and weary
Trying to come up with a subject for a poem
Suddenly there came a tapping
Is that you, Mom? I'm not napping!
Yes I'm working on my homework, up here all alone
Quickly I signed off of Facebook
Started writing, as my hand shook
From the caffeine in my diet coke
From there, you would tell how the raven came in, scared you, or yelled at you to "GET BUSY DOING YOUR ASSIGNMENT" - in the voice of your teacher - and then at the end, you can wake up and find it is all a dream and you did not complete the assignment after all.
If you don't like that idea, perhaps choose a poem by Emily Dickinson - they are mostly short ones and might be easier to inspire you.
