1) Critical reading involves a deeper examination of the claims in a text as well as considering possible counterarguments rather than just taking the text at face value.
2) Skimming a text involves only superficial understanding while critical reading examines logical consistency, tone, organization and other important elements to gain deeper understanding.
3) To be a critical reader, one should learn about the author and context, read with an open mind seeking knowledge, consider the title which provides clues, read slowly to make connections, use references to define unclear words, take notes on main ideas and the author's points, and keep a reading journal to record responses.
