自行车— Part 1 评分报告

建议: 句子时态和语法不正确，表达也较简单。回答应使用过去时（because asking about past），并给出一到两句补充细节，比如谁给你的，骑车的经历或你喜欢骑车的原因。同时注意句子自然流畅并避免多余词语。

示例: Yes, I did. I had a red bicycle when I was a child, and I used to ride it to school every day. It was given to me by my parents and I loved racing with my friends in the neighborhood.

建议: 回答基本能传达信息，但结构略显口语化且有停顿词（uh）。应用更完整流畅的句子，并给出具体细节来支持观点，例如使用范围、使用人群或优点。使用连接词使句子更连贯。

示例: Yes, I think bikes are very popular, especially in big cities. For example, many people use public shared-bike systems for short trips because they are cheap and convenient, and they help reduce traffic congestion.

× Yes, I have a bike when I'm a child.

✓ Yes, I had a bike when I was a child.

语法问题类型 ID: 6（现在时问题）。原句中学生用现在时态“have”与“I'm a child（我现在是个孩子）”混用，但问句是关于过去的情况“Did you have... when you were a child?” 应使用过去时。应把“have”改为过去式“had”，并把“I'm”改为过去式“I was”。建议：回答过去发生的事情时，整个描述应使用过去时（例如：I had a bike when I was a child.）。

× Yes, we have public shared bike system in my country and uh, the city where I lived.

✓ Yes, we have a public shared bike system in my country and in the city where I lived.

语法问题类型 ID: 22（冠词错误）和 ID: 11（介词使用错误，因主要问题是冠词）。原句缺少不定冠词“a”来修饰可数名词“system”，正确用法为“a public shared bike system”。另外，原句末尾缺少介词“in”来连接“the city where I lived”，应为“in the city where I lived”。建议：可数单数名词前需要适当的冠词；表示“在……城市”用介词 in（例如：in the city where I lived）。
