Bike— Part 1 Báo cáo

Gợi ý: 回答过于简短，缺乏细节和结构。应先用一句主题句直接回答，然后用一到两句补充细节（如什么时候有、是什么样的自行车、是否常骑、为何喜欢或记忆深刻），并使用连接词使表达更自然连贯。控制在最多5句内。

Ví dụ: Yes, I did — I got my first bike when I was about eight years old. It was a small red bicycle with training wheels, and I used to ride it around my neighborhood almost every day. Because it gave me a lot of freedom, I still remember learning to balance without the training wheels.

Gợi ý: 回答不完整且含糊。应先给出明确立场（肯定或否定或部分同意），然后用一到两句具体理由或例子支撑观点，使用连接词（例如“because”、“however”）使逻辑清晰。避免中断句或不完整句。

Ví dụ: I think bikes are fairly popular in my country, especially in cities. For example, many people use shared bicycles for short commutes because they are cheap and convenient, although cars are still more common for longer trips.

× Not sure but.

✓ I'm not sure, but I think so.

学生原句为片段句，缺少主语和谓语，属于句子结构错误（Grammar Problem Type 26）。“Not sure but.” 省略了主语“I”和系动词“am”，使句子不完整。建议使用完整句子表达：例如“I'm not sure, but I think so.” 或 “I'm not sure, but many people do.” 保持与问题时态和语境一致，使用完整主语+谓语结构以使表达清晰。
