Bike— Part 1 채점 보고서

제안: 你的回答没有直接回应问题，而且时态错误。首先要用过去时直接回答（例如：Yes, I did 或 No, I didn’t），然后给出一至两句具体细节来扩展（比如你几岁开始有的、车是什么样的、你用它做什么）。注意把句子控制在不超过5句，用连接词使内容连贯。

예시: Yes, I did. I got my first bike when I was seven, and it was a small red bicycle with training wheels. I used it to ride around my neighborhood every afternoon, which helped me become more independent.

제안: 回答太简短且缺乏细节。应该先给出直接回答（Yes/No），然后用一到两句具体理由或例子支持你的观点，例如提到城市里骑车的人多、共享单车的普及或政府的自行车道建设。使用连接词（for example, because, so）使表达更自然且逻辑清晰。

예시: Yes, I think bikes are very popular in my country because many people use them for short trips and commuting. For example, shared-bike programs are common in cities, and many neighborhoods have bike lanes that make cycling convenient and safe.

× Do you have a bike when you were a child?

✓ Did you have a bike when you were a child?

问题类型：过去时使用错误。学生回答中使用了现在时的助动词“Do you have”，但提问对象是过去（“when you were a child”），应使用过去时“Did you have”。建议：遇到表示过去时间的时间标志（如 when you were a child, yesterday, last year）时，主句动词要用过去时；一般疑问句用助动词 did + 主语 + 动词原形。

× Yes, I do.

✓ Yes, I did.

问题类型：时态一致性错误。学生用“Yes, I do.”作肯定回答与前一句（询问过去经历）时态不一致。正确的短回答应该与问句时态一致，若问句是过去时（Did you...），则回答应用“did”。建议：回答简短问句时，注意与问题的时态保持一致：过去时用 did/ didn’t，現在時用 do/ don’t，第三人称單數現在用 does/ doesn’t。
