written work for application

[Guest]

hi

I'm an international student who would like to apply for Oxford for 2007. The course I want to apply for requires to submit written work in English, however I don't have such written work available.
Can anbyody help me how to write such a work specifically for that issue ? How does "typically" (if there is such a thing) written work for an application looks like and what should it contain ?

thanks for any help.
