Answer (106 words):
Dear Ben,
How are you? I want to tell you about my school life. These days, we are preparing for an English test, so I am studying more than usual. I have already finished my project, but I haven’t shown it to the teacher yet. I often play volleyball with my classmates after lessons. We have been friends for three years. Yesterday, we had a science lesson, and it was really interesting. My favourite subjects are English and biology because they help me understand the world. Tomorrow, I am going to visit the library. I hope to hear from you soon. Write back!
Best wishes,
Alex
