I am Leo， an exchange student of a seniorhighschool in China. Outgoing as I was， I felt anxious in the beginning. I was frightened that I would meet awkward or annoying situations and leave a bad impression on others. But nothing happened. The students and teachers’ kindness impressed me deeply.
As a newcomer， I am curious about everything. My new friend Leilei keeps me company when I explore the campus. He introduces the style of the lecture hall， the design of our uniform， and the organisations in the school. He also helps me improve my Chinese！
In class， I concentrateon the study and takenotes carefully. I am lookingforwardto doing experiments with my partners next week！Whatif we make mistakes？ Well， the teachers will never leave us alone for the sake of our safety. I am confident that we will make it atlast.
