Help with High School Students?

I need some advice/help. I work at a high school as a tutor. Now keep in mind these students are not from a very good side of town, many of them are juniors and seniors with the comprehension of a freshmen. I tutor reading, writing, english, history, and social studies. I need some ideas on what to do especially on the reading part. Any websites with work sheets? Reading ignments? Comprehension ignments. Any help please!
