Sure! Here's the updated version with the teacher's brief self-introduction added:
As everyone was preparing for PE class, Su Feiyan felt a tight knot in his stomach. He had only attended PE classes at a school for the blind before, where the setup was very different. He had no idea what to expect from a regular high school PE class. His mind raced with questions: What if the teacher doesn't let me participate? What if I can't keep up with the others? His nerves were on edge as they walked toward the playground. The high school track stretched out in front of him, its red rubber surface gleaming under the morning sun. The track had white lines marking the lanes, and the smell of freshly cut grass mixed with the faint scent of rubber from the track. The sound of students' shoes against the ground, the rustling of wind, and distant chatter filled the air.
Teacher Huang stood by the starting line, waiting for the class to assemble. As everyone lined up, Su Feiyan positioned himself at the back of the group, feeling out of place. His heart pounded in his chest, and he took a deep breath to steady himself.
Teacher Huang stepped forward and addressed the class with a warm smile: "Hello, everyone. I'm your PE teacher, Huang." He paused for a moment before continuing, "PE isn't just for fun. It's essential for your health. Many high schools treat it as a formality, but that's a mistake. Exercise is vital for maintaining a healthy body. If you neglect it, your body will suffer. Remember, your health is your foundation—everything else depends on it." Su Feiyan stood quietly, absorbing his words, feeling a little more at ease as the teacher's reassuring tone helped calm his nerves.
Next, Teacher Huang called for a warm-up run. The students began jogging around the track, their feet pounding on the soft rubber surface. Su Feiyan's roommates, noticing his hesitation, kindly invited him to join them. "Don't worry, we'll guide you," they assured him, their voices steady and clear. They helped him navigate the track, telling him when to turn or when there was an obstacle ahead. It was the first time they had done this, and it felt both new and helpful.
After the run, Teacher Huang began demonstrating pull-ups and patiently explained the correct form and movements. "Focus on your form," he emphasized. Many students tried, but none succeeded. Laughing, Teacher Huang teased, "Did you all spend the whole summer in bed or in front of your computers?" The class laughed, and the atmosphere became lighter.
Su Feiyan wasn't afraid of doing pull-ups. Despite his small, slender build, he knew from his childhood experiences that having a strong body was very important. So, he didn't hesitate to give it a try. Teacher Huang, however, was a bit worried. He wondered how many pull-ups such a small body could manage.
With the encouragement of his classmates, Su Feiyan started doing pull-ups. To everyone's surprise, he managed to do 12 in a row! Teacher Huang and his classmates were all amazed and applauded him. Su Feiyan felt a little embarrassed, especially when he heard Lin Xi's admiring voice: "Wow, you're really amazing! I couldn't do a single one!"
Su Feiyan smiled modestly and replied, "No, no, it's just about doing more exercise."
Lin Xi, excited, asked, "Can you teach me sometime?" Su Feiyan smiled and agreed, "Of course."
Their conversation was quiet, so no one else noticed. After a few more minutes, Teacher Huang called Su Feiyan over and said, "Su Feiyan, can you stay a little longer after class? I have a few things I'd like to talk to you about." The rest of the class dispersed, and Su Feiyan stayed behind, wondering what Teacher Huang wanted to say.
