Reflections on reading summarization teaching were presented for exploring critical problems hidden in the shadow, including: differences among synopsis, purpose, and abstract; reading summaries of various types of libretto; influences of reading purposes to abstracts; considerations of methods and teaching on summarization. Researcher believed that there were dialectical spaces in reading summarization. In other words, there were hints for further deliberation between right and wrong in concepts. As mentioned above, researcher attempted to provide a new perspective of thinking besides often seen theories of summarization as references for reading summarization teaching in the future.
