Bike— Part 1 채점 보고서

제안: 回答过于简短，未直接展开细节或使用连词。应先用主题句直接回答，然后补充1–2个具体细节（如什么时候有、谁给的、常去哪里骑或相关感受），并保持不超过5句。使用连词如“because”或“and”使表达更连贯。

예시: Yes, I did. I got my first bike when I was seven from my parents, and I used to ride it to the park every weekend because I loved racing my friends.

제안: 回答仅有肯定词，缺乏理由和具体例子。应先给出明确立场，然后用一两句说明原因并举例支持（比如通勤、环保或运动用途），使用连接词如“because”或“for example”。保持自然用词并控制在5句以内。

예시: Yes, I think so because many people use bicycles for short commutes and exercise. For example, in my city there are dedicated bike lanes and shared-bike services that lots of students and office workers use.
