Homework Finish the related exercises in the books produced by Youyi. Blackboard Design Write some important grammar rules on the blackboard. Teaching Reflection In this lesson,we focused on wh-questions,using “because”to connectsentences, and plural noun rules, and students mainly learned these points through pair discussions and grammar exercises. A small number of students still struggled with irregular plural nouns, so they needed more one-on-one guidance. To address this, I plan to add 5-minute quick drills on irregular plurals in the next class to help them master this part better. 学科网（北京）股份有限公司 $
