genki isnt the best book out there but usually it gives decent samples, apart fomr repatingitself a milliontimes over with the verb taberu eg.

i was told that Shi "mainly" is used when listing things or properties of the subject at matter like; 彼女はかわいいし、やさしし... and also mainly when you want to put a lot of things together ;p i think of it as a substitute for _and_

but overusing it makes you look like a kid ;p
