Reading Explorer is a six-level, content-based reading series that leverages National Geographic's vast library of digital media to help learners improve their vocabulary and comprehension. The series typically starts at "Foundations" and progresses through five subsequent levels, with Level 5 (the sixth book) catering to advanced students preparing for high-stakes academic environments.
The readings themselves are adapted to be accessible yet challenging. They retain the sophistication of the original source material but are tweaked to ensure flow. What sets Level 6 apart from earlier levels is the sentence structure. Students encounter complex grammatical structures, passive voice, nominalization, and academic transitions, requiring them to possess a strong grasp of advanced syntax. reading explorer 6
