Bike— Part 1 채점 보고서

제안: 回答过去经历时要使用过去时，不能用现在完成时态的“Yes, I have”来回答。先直接回答“Yes, I did”，再补充一条具体信息，例如自行车的颜色、用途或骑车地点。

예시: Yes, I did. I had a small blue bike, and I often rode it around my neighborhood after school.

제안: 需要直接说明自行车在你所在国家是否受欢迎。“I think so very good”表达不自然，也没有提供具体理由。可以用“I think they are quite popular”作答，并补充用途、受欢迎的原因或常见骑行场景。

예시: Yes, I think bikes are quite popular in my country. Many people use them for short trips because they are convenient and inexpensive.

× Yes I have

✓ Yes, I did.

问题使用了过去时疑问句“Did you have...?”，回答时应使用助动词“did”呼应过去时。这里的“have”不能用于回答该过去时问题。

× I think so very good.

✓ I think so; bikes are very popular.

“I think so”已经是完整表达，后面直接接“very good”缺少主语和谓语，句子结构不完整。可以补上主语“bikes”和系动词“are”，并用“popular”回应问题中的“popular”。
