Yo this is great for beginners. This is probably the first beat I ever used. 

 H| x-x-x-x-x-x-x-x-|x-x-x-x-x-x-x-X-|
 S| ----o-------o---|----o-------o---|
 B| o-------o-o-----|o-----o---o---o-|

For which a good fill could be...

H|x-x-x-x-x-x-----|
S|----o-------oooo|
B|o-----o---o-----|
When you get more advanced, you can play with this beat. Maybe something like...

H|x-x-x-x-x-x-x-x-|x-x-x-x-x-x-x-X-|
S|----o-------o---|----o-------o---|
B|o-------o-oo----|o--o--o---oo--o-|
