Bike— Part 1 채점 보고서

제안: 回答童年经历时要使用一般过去时，不能说“Yes, I have”，应说“Yes, I did”。还可以补充一两个具体细节，例如自行车的颜色、什么时候骑，或通常和谁一起骑，让回答更完整自然。

예시: Yes, I did. I had a small blue bike when I was about eight, and I often rode it around my neighborhood with my friends.

제안: 回答直接且语法正确，但内容过于简短。“I think so”后应补充具体理由或例子，例如人们骑自行车通勤、锻炼，或使用共享单车。用连接词衔接理由，可以让回答更有逻辑。

예시: Yes, I think bikes are quite popular in my country. For example, many people use them for short commutes because they are convenient and affordable.

× Yes, I have.

✓ Yes, I did.

问题问的是过去的情况（“Did you have...?”），回答时应使用与过去时疑问句对应的助动词 did。这里用了现在完成时助动词 have，时态不一致。回答过去时的一般疑问句时，可用“Yes, I did.”
