This document discusses techniques for teaching English tense and aspect to Chinese students. It provides examples of verbs in different tenses and aspects, such as "fall asleep" and "be asleep". It also includes diagrams illustrating the distinctions between actions and ongoing states. Some suggested teaching methods are using timelines, pictures, role playing, and physical objects like pencils and rubber bands to demonstrate tense and aspect visually and experientially. The document was adapted from a 2002 paper on training Chinese students to recognize words that indicate lexical aspect in English.
