Think about it, what kind of picture does the poem depict? Grasp the following things to answer this question: trees (plants), ducks (animals), birds below, Woods and hills. "What is the author's mood?" Obviously, the article means "jumping for joy". There is no essential difference between the third question and this one. The second question is how you play. In fact, it is a kind of possession, and I don't want it (which can be understood as "spring") to be destroyed.
