But everything changed when I entered junior high school. My new English teacher encouraged us to share our thoughts freely. One day, we had a discussion about how to make our school more beautiful. At first, I was quiet, but then I remembered how I loved planting flowers in my garden. I raised my hand and suggested we plant more flowers and trees around the school. To my surprise, my classmates liked my idea. We worked together to plan the project. We asked the school to give us seeds and tools, and we spent our after-school time planting. Soon, our school was filled with colorful flowers and green trees. This experience taught me that everyone’s ideas matter. Now, I am not afraid to speak up. I often join in group discussions and share my creative thoughts. I believe that even small ideas can make our school and our world better. 根据短文内容，回答下列问题。 41．How did the writer feel about speaking in front of others in primary school? ___________________________________________________________ 42．Who encouraged the writer to share thoughts freely in junior high school? ___________________________________________________________ 43．What idea did the writer suggest to make the school more beautiful? ___________________________________________________________ 44．What did the writer learn from this experience? ___________________________________________________________ 45．What changes have you made in expressing your ideas since junior high school?
