Bike— Part 1 채점 보고서

제안: 句子时态和完整性需要改进。回答应使用过去时并提供一点细节以显得自然，例如说明你什么时候有自行车、谁给的或你如何使用它。尽量用一到两句，不超过五句。可以使用连接词如“and”或“when”来连接信息。

예시: Yes, I did. I had a bike when I was about eight, and my parents bought it for me as a birthday present. I used to ride it to the park every afternoon with my friends.

제안: 表达不清且语法混乱。首先直接回答问题，然后给出具体理由和对比，使用连接词（for example, however, because）使表达连贯。注意时态和词汇（e.g. popular, transportation）。尽量提供具体证据或例子说明趋势变化。

예시: I think they were more popular in the past, but less so now. For example, many people used to cycle regularly, however today most prefer cars or public transport because cities have become more congested and cycling infrastructure is limited.

× Yes, I have.

✓ Yes, I did.

问题类型ID：6（现在时问题）。原句使用现在时“have”回答过去时问题“Did you have...?”，时态不一致。应使用过去时“did”。改进建议：遇到以Did开头的过去时问句，回答时用过去时（例如：I did / I didn't）。

× No, it it had popular, but now, uh. As a trans transportation instead it.

✓ No, it was popular, but now it's used more as a means of transportation.

问题类型ID：26（句子结构错误）。原句结构混乱，包含多处错误：重复词“it it”、错误时态和词序，以及不正确的词汇短语“trans transportation”。应把句子整理为完整的过去与现在对比句，并使用正确的词组“means of transportation”。改进建议：先确定主语和谓语，避免重复词，使用正确的名词短语（means of transportation），并保持时态一致（过去：was popular；现在：is used）。
