Well you can teach a student how to read a passage, but if they're just memorizing it, you're not really teaching them anything.
What sort of level are we talking about here? Do they know how an "e" on the end of a word changes the pronunciation, for example? Have they been taught how "though/thought/rough/through/cough/plough" are pronounced differently?
I'm not a teacher yet, but personally, I would approach it by looking at the passage, and seeing what sort of English language rules are present that you could teach them. Then put it all together, so they can read it, and anything else containing the same rules, without just memorizing it.
