Bike— Part 1 채점 보고서

제안: 回答过于简短，未遵循“基本结构”与“内容”规则。建议用主题句直接回答后补充具体细节（如什么时候得到、使用频率、原因或印象），并用连接词使表达连贯。目标回答不超过5句。

예시: Yes, I did. I got my first bike when I was seven and used it almost every weekend to ride to the park with my friends. Because it was lightweight and bright red, I felt confident riding it on small hills. That bike helped me learn balance and independence.

제안: 回答太笼统，缺乏具体支持。建议先给出直接观点，然后用一到两句具体原因或例子支持，例如使用场景、统计观察或个人见闻，并使用连接词如“because”或“for example”。保持不超过5句。

예시: Yes, I think so because many people use bicycles for short trips in cities and students often cycle to school. For example, I see crowded bike lanes during rush hour and several bike-sharing stations near subway exits.

✓ Yes, I think so.

该回答在所给上下文中语法正确。问题为一般现在时（Do you think...），学生用“Yes, I think so.”正确表达意见，时态和结构均无错误。无需更正。
