Bike— Part 1 채점 보고서

제안: 回答缺乏相关性与清晰性。首先要直接回应“过去是否有自行车”的过去时问题（例如用过去时），并给出简短理由或细节以展开内容。可使用1-2个连接词或简单原因来丰富答案，但不要超过5句话。

예시: No, I didn’t have a bike when I was a child. My family lived in a small apartment, so there wasn’t enough space to keep one. Instead, I usually walked to school with my friends.

제안: 回答太简短且口语化，缺少具体细节和连接词。应使用完整句子并给出原因或例子来支持看法（例如谁骑车、在什么情况下、比较或趋势）。使用连接词如“because”或“for example”来使答案更连贯。

예시: Yes, bikes are quite popular in my country because many people use them for short trips and commuting. For example, in cities you can see a lot of cyclists during rush hour, and bike-sharing programs have also become common.

× No, I don't know.

✓ No, I didn't.

语法问题类型ID 26：句子结构错误。原句为“No, I don't know.” 回答过去是否拥有自行车，时态应为过去式。使用“I don't know”表示现在不知道，与问题时态不一致且不直接回答“有/没有”。应使用过去时的否定“I didn't”或更完整“I didn't have a bike.” 建议回答时与问题时态一致，直接用过去式否定或完整句子。

× Yes, really, really. People like it.

✓ Yes, definitely. People like them.

语法问题类型ID 27：主谓一致/代词一致错误。原句中“People like it.” 使用单数代词“it”指代复数名词“bikes”，代词与先行词在数上一致性错误。改为复数代词“them”或将句子改为泛指单数时使用“It is popular.” 建议改为“Yes, definitely. People like them.” 或“Yes, really. Bicycles are popular.” 此外把重复的“really, really”改为更自然的“definitely”。
