Bike— Part 1 채점 보고서

제안: 回答切题，但时态不正确：问题询问童年经历，应使用过去时“did”，而不是现在完成时“have”。建议先直接回答，再补充一项具体信息，例如自行车的颜色、用途或骑车的地点。

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

제안: 回答表达了你的观点，但主谓一致有误：“bikes”是复数，应使用“they are”，不能用“it’s”。“popular”后可补充具体理由或例子，让回答更充分；注意控制在几句话内。

예시: Yes, I think bikes are quite popular in my country. They’re especially common in cities because they’re affordable and convenient for short trips.

× Yes I have

✓ Yes, I did.

问题类型：过去时错误（ID 5）。问句使用过去时助动词“did”，简短肯定回答也应使用“did”，不能用“have”。建议根据问句的时态选择相同的助动词回答。

× Yes it's very popular in my country

✓ Yes, they are very popular in my country.

问题类型：代词使用错误（ID 12）。这里的“they”指代复数名词“bikes”，不能用单数代词“it”。相应地，谓语也应使用“are”。建议先确认代词所指的名词是单数还是复数，再选择匹配的代词和动词。
