Teaching Reflection This lesson effectively helped students distinguish between infinitives as object complements and adverbials through clear examples and interactive exercises. Though most students understood the concept,some had difficulty identifying the logical subject of the infinitive phrases. Next time,I'll use simpler terms like “action performer”and more sentence diagrams. The exercises worked well,but I'll add pair work for deeper practice. 学科网（北京）股份有限公司 $
