Today is my first school day in senior high school. I was a little anxious because I wanted to make a good first (impress) on others. In the morning, I had my first maths class is quite difficult for me. (lucky), the teacher and most classmates were kind-hearted friendly. The teacher even told a funny story, making everyone laugh. In the afternoon, we had interesting chemistry class in the newly-built lab. However, a guy beside me always tried to talk to me. What he did stopped me from (concentrate) on those interesting (experiment), and all that (annoy) me greatly. At the end of the day, my worry disappeared. I no longer felt awkward or (frighten). instead, I began to feel much (confident) than I felt this morning.
