Bike— Part 1 채점 보고서

제안: 语法和时态错误明显，需要用过去式，句子要更自然并提供简短细节。建议改为简单的主题句+一到两句支持细节，使用连接词使表达更连贯。比如说明什么时候、谁给的或你经常怎么用。

예시: Yes, I did. I had a small mountain bike when I was a child. I often rode it around my neighborhood with my friends, and it was a gift from my parents on my eighth birthday.

제안: 回答太简短且缺乏具体细节。建议先给出直接回答，然后用一至两句具体原因或例子支持，使用连接词如 'because' 或 'for example' 来衔接。还可以提到城市/农村差异或骑行用途。

예시: Yes, I think they are quite popular because many people use bikes for short trips and exercise. For example, in big cities there are bike-sharing programs, while in rural areas people often use bicycles for daily errands.

× Sure, I have a mountain bike when I was a Cho child.

✓ Sure, I had a mountain bike when I was a child.

该句中问句是过去时（Did you have... when you were a child?），回答也应使用过去时。原句使用现在时“have”与从句“when I was a child”（过去时）时态不一致，且“Cho”似为拼写或多余词。改为过去时“had”并删除多余词，句子时态一致。建议：在描述过去发生的事情时，用过去时态（如 had, was）。

× Yes, bikes are popular in my country.

✓ Yes, bikes are popular in my country.

此句原本语法正确，时态使用为一般现在时，适用于陈述事实或普遍真理。无需修改。
