okay this is how my thesis statement is supposed to be formed:
1. must use an action verb
2. must be an active voice sentence
(the subject doing the action, not the action done by the subject)

My Research paper is on the poet Dylan Marlais Thomas!

The Working Thesis:

Once the preliminary outline is completed, the student should then develop his or her working thesis. This is a statement that identifies the focus of the research. It should refer either directly or indirectly to the three major points included in the preliminary outline. The thesis statement must be written in active voice using an action verb. Active voice means that the subject of the sentence directly accomplishes the action of the verb. The thesis statement should be printed above the outline, but after the title of the paper (Dylan Marlais Thomas).

This is how my english teacher wants it done! So here is my outline it might help a little!
