I agree, don't just ask questions they can easily answer, get then to infer information from the text. A simple example: Say if he was reading about a man who was in the cafe ready to go outside and he was holding an umbrella. You could ask him what kind of weather do you think it is in the story? He'd reply 'it could be reining as the man has an umbrella with him.' So the text didn't actually mention the weather but he's inferred the information.
We were given the above example in the school I work at. I've found the link incase I didn't explain it very well ...http://www.bgfl.org/bgfl/custom/files_u ... n3_HO1.doc
