Bike— Part 1 채점 보고서

제안: 回答直接，但时态错误：问题询问过去，应使用“Yes, I did”，而不是“Yes, I have”。可以再补充一两句具体信息，例如自行车的颜色、用途或骑车的地点，让回答更自然完整。

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

제안: 表达不完整。“Yes, I think”后面需要补充具体观点。建议说明自行车是否普及，并用一个原因或例子支持观点，例如通勤、锻炼或短途出行。

예시: Yes, I think bikes are quite popular in my country, especially in smaller cities. They’re an affordable and convenient way to get around for short trips.

× Yes, I have.

✓ Yes, I did.

问题问的是过去（Did you have a bike when you were a child?），简短肯定回答应使用与问句助动词对应的过去式 did，而不是现在完成时助动词 have。回答过去时的一般疑问句时，可使用“Yes, I did.”

× Yes, I think.

✓ Yes, I do.

问句使用一般现在时助动词 do（Do you think...），简短肯定回答通常使用“Yes, I do.”来重复助动词。单独说“Yes, I think”在这里不是合适的简短回答；若保留 think，应补全其内容，例如“Yes, I think they are.”
