三、閱讀理解（圍繞“好奇心與探索”主題，滲透不定式用法）
A篇：Curiosity in Preschoolers
Preschoolers are famous for their never-ending questions. They want to know why the sun shines, how ants carry food, and where rain comes from. This inborn curiosity is important for their brain development.
Researchers say that answering their questions can deepen their understanding of the world. It's not good to ruin their curiosity by saying "It's just like that." Instead, we should encourage them to explore—maybe by watching a cartoon about nature or visiting a metro station to see how trains work.

A recent study shows that curious people are better at learning. They are not afraid to try new things or make mistakes. Their brains work faster when they try to understand something new.

四、書面表達（參考范文）
My Curious Moment
Last summer, I saw ants carrying food and wanted to know how they communicated. I decided to watch them carefully. My grandpa encouraged me to do a small experiment: I put a piece of bread near their nest and waited.
It was interesting to see how they worked together. I tried to follow one ant to find its home, but it was too fast. My grandma suggested me to read a book about ants, which helped me understand their behavior.
I was happy to learn that ants use touch and smell to "talk". This experience taught me to never stop wondering and to try to find answers. It made me want to explore more about nature.
