Bike— Part 1 채점 보고서

제안: 回答过于简短，没有明确陈述主题句或提供细节。应扩展为一到三句，说明是否有自行车、什么时候拥有、用途或与之相关的回忆，并使用连接词使表达更自然。举例：说明年龄、谁给的、常去哪儿骑、感受等。

예시: Yes, I did. I got my first bike when I was about six, and I used to ride it to the park every afternoon with my friends. It made me feel very independent and helped me make lots of childhood memories.

제안: 回答太简短且缺乏支持性细节或原因。应给出一个明确的主题句并补充具体理由或例子，使用连接词（for example, because, since）来增强逻辑性。可以提到城市/乡村差异、通勤、健康或环保等原因。

예시: Yes, I think bikes are quite popular, especially in cities. For example, many people use them for short commutes because riding is cheap and helps avoid traffic, and there are also public bike-sharing schemes that make cycling convenient.

× Yes.

✓ Yes, I did.

原句只回答“Yes.”在回答过去时的问句（Did you have...）时，应使用完整句子或带助动词的短语以明确时态。建议在回答过去式疑问时使用“Yes, I did.”或“No, I didn’t.”以保持时态和结构一致。

× Yes.

✓ Yes, I think they are.

原句仅用“Yes.”回答关于现在时的问句（Do you think bikes are popular...）太简略，且没有明确主语和谓语。为了与问题保持时态一致并明确观点，建议使用完整句子，如“Yes, I think they are.”或“Yes, they are popular in my country.”
