The comprehension of literature places different demands upon children than the comprehension of non-imaginative prose. This is because, in order to comprehend literature, children must enter and understand the highly imaginative worlds of literary creation. Although these worlds are charged with delight for the child, they are at the same time essentially unreal- they are the imaginative productions of their creators.
