Research in strategy use needs to provide comprehensive and detailed qualitative discussion of individual cases and their strategic processing of texts to deepen our understanding of the cognitive and metacognitive processes readers resort to when reading different texts for different purposes. Hence, the present paper aims to provide in-depth and rich examination and interpretation of four Saudi EFL students (two good and two poor readers) processing two different texts in structure (a narrative and an expository text) for different reading tasks. This involved a detailed qualitative discussion of the differences and similarities in reading problems and strategy use. Using think-aloud reports and follow-up interviews, the study identified four explicit word-related and six text-related problems reported by the four EFL readers in processing the assigned text types. Moreover, the study revealed how the selected cases varied in their strategic reactions to the reading problems encountered in the two texts. The study findings also demonstrated how the structuring variations of the narrative and expository texts had a considerable effect on the quantity and quality of readers' reported difficulties and reading strategies employed in texts.
