Bike— Part 1 채점 보고서

제안: 回答过于简短且缺乏细节。请首先用一句话直接回答问题，然后提供1–2个具体细节来丰富内容（例如谁给你的、你常骑去哪儿、一次特别的记忆等）。尽量使用连接词（例如“and”、“so”或“because”）保持连贯，总句数不超过5句。

예시: Yes, I did. My parents bought me a small red bike when I was seven, and I used to ride it to the park every afternoon. I remember practicing until I could ride without training wheels, which made me feel very proud.

제안: 回答模糊且语法不完整。应直接表达观点并给出具体理由或例子，比如讨论通勤、健身或环境保护方面的原因。使用连接词（such as “because”, “for example”, “also”）使回答更有条理，总句数控制在最多5句。

예시: Yes, I think bicycles are quite popular in my country because many people use them for short commutes and exercise. For example, in cities there are dedicated bike lanes and shared-bike services, which make cycling convenient and affordable.

× Yes, yes.

✓ Yes, I did.

原句“Yes, yes.”在回答过去时问题（Did you have...?)时只重复“Yes”不能明确体现过去时态，也缺少动词，属于句子结构不完整。建议在回答过去时的封闭式疑问时使用简短完整句，如“Yes, I did.”或“Yes, I had a bike.”，以明确时态和主谓。

× Uh, I do.

✓ Yes, I think bikes are popular in my country.

原句“I do.”虽然语法上可以作为简短回答，但在回答“Do you think bikes are popular in your country?”时更自然的是完整陈述观点，使用一般现在时表达普遍事实。建议使用完整句“I think bikes are popular in my country.”或“Yes, I think so.”以更清晰地表达意见。
