Language points
I was the tallest student in my class. Now, I’m still the tallest. I sat on the last row in primary school. Now at junior high, I’m sitting on the last row. Poeple always look at me in surprise. “You must be good at basketball,” my classmates at primary school always said that. Now at junior high, my classmates say the same. In fact, I’m not good at basketball at all. But being tall is not always bad. It makes me easy to recognise, and I can help others reach things down. I couldn’t accept my height, but I learn to do it now. I’m proud of myself.
be good at sth./doing sth. 擅长某事/做某事
伸手拿东西
