Reading comprehension refers to the ability to understand and interpret written text. It involves not only being able to read words accurately, but also understanding their meanings in context, as well as grasping the overall structure and organization of a piece of writing. Good reading comprehension requires active engagement with the material, such as identifying main ideas, making connections between different parts of the text, and recognizing the author's purpose or perspective. It is an essential skill for academic success and is often tested through standardized tests and other assessments.
