Bike— Part 1 채점 보고서

제안: 回答直接，但不够完整和自然。建议：1) 用一到两句主题句直接回答并说明原因；2) 使用连接词使句子更流畅（例如 because, so, although）；3) 添加具体细节（如你当时如何出行、有无骑车经历或感受）。注意语法（mother 而非 mum 在正式场合可用 mother 或 mum，但句子需要时态和冠词准确）。示例句子不超过5句。

예시: No, I didn't have a bike when I was a child because my mother thought it was too dangerous. So I usually went to school by bus or walked with my friends. Although I wanted one, my parents worried about traffic and safety, especially since we lived near a busy road.

제안: 回答不完整且有语法错误，信息不清晰。建议：1) 先直接回答（Yes/No/It depends），然后用一两句具体解释或举例；2) 使用连接词（for example, however, because）来衔接观点和细节；3) 注意句子完整性和语法（主语、动词、时态）；4) 提供具体信息如城市与农村差异、近年来趋势或个人观察。

예시: It depends on the area. In big cities, bikes are becoming more popular because there are bike lanes and bike-sharing schemes, but when I was a child most of us travelled by bus since public transport was convenient and safer. For example, my friends and I usually took the bus to school rather than biking.

× I didn't have a bike because my mum thought it's very dangerous

✓ I didn't have a bike because my mum thought it was very dangerous.

问题类型：第三人称单数/时态一致问题。原句中主句是过去时（"didn't have" 和 "thought"），从句使用了现在时缩写 "it's"，时态与主句不一致。应将从句改为过去时的 "it was"。建议：在叙述过去的事情时，从属句也要使用过去时以保持时态一致。用完整形式（it was）比口语缩写更正式准确。

× Actually, when I was a kid our friends and the I always by bus.

✓ Actually, when I was a kid, my friends and I always went by bus.

问题类型：句子结构错误。原句缺少动词并且词序混乱（"the I" 是错误的词序和多余的定冠词），同时动词时态应为过去时以配合 "when I was a kid"。应改为 "my friends and I always went by bus"。建议：注意主语顺序为 "my friends and I"，使用过去时动词 "went"，并在从句前后加逗号以提高可读性。
