Bike— Part 1 채점 보고서

제안: 你的回答不清晰且自相矛盾。建议：1) 直接回答问题（肯定或否定），2) 用一句主题句说明情况，3) 用最多两句提供具体细节或原因，使用连接词使句子连贯。例如可说明什么时候有或没有、谁借给你、或你为什么没有自行车。练习时注意语速和流畅性。

예시: No, I didn’t have a bike when I was a child. My family couldn’t afford one, so I usually walked to school instead. However, I learned to ride much later when I was a teenager and borrowed my friend’s bike.

제안: 你的回答太简短且没有展开。建议：1) 给出明确立场（认为流行或不流行），2) 用连接词（e.g., because, for example）提供具体理由或例子，3) 保持回答在最多五句内。可以提及交通状况、城市与乡村差异、环境意识或共享单车等因素。

예시: Yes, I think bikes are quite popular in my country because many people use them for short trips in cities. For example, bike-sharing programs are widespread, and in rural areas people often use bikes for daily errands.

× No, yes, I don't. I don't know.

✓ No, I didn't. I don't know.

问题类型：句子结构错误。学生回答“Did you have a bike when you were a child?”（过去时）时，应以过去时简短回答。原句“No, yes, I don't.”结构混乱且时态不匹配。建议改为“No, I didn't.”表示过去没有。后半句“I don't know.”可以保留表示不确定。改进建议：回答关于过去的问句时使用过去时（如：I did / I didn't）。

× I don't know.

✓ I don't know.

问题类型：现在时问题（但本句在语法上是正确的）。该句话用于表达当前不确定性，时态使用正确，无需修改。建议：若在谈论普遍事实或习惯也可用“I don't know”或更完整的句子“I don't know if bikes are popular in my country.”以提供更多信息。
