Bike— Part 1 채점 보고서

제안: 回答直接，但时态错误：问题问的是过去，应将“I have”改为“I did”或“I had”。还可以补充一条具体信息，例如自行车的颜色、骑车地点或骑车经历，让回答更完整。

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

제안: 目前没有清楚说明自行车是否受欢迎，句子“I seen a bike can go to the park and take a bike”语法和意思都不清楚。先直接回答“Bikes are quite popular”，再用具体原因或例子支持观点；描述常见情况时可用一般现在时，例如“people ride bikes to the park”。

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

× Yes, I have.

✓ Yes, I did.

问题问的是“小时候有没有自行车”，使用一般过去时。回答时应使用助动词 did 来对应问句中的 did；have 与问句的时态不一致。

× Yes, I seen a bike can go to the park and take a bike.

✓ Yes, I have seen people ride bikes to the park.

“seen”是过去分词，不能单独用作一般过去时；这里应加助动词 have，构成现在完成时 have seen。也可以根据想表达的意思改用一般现在时，例如“I see people riding bikes to the park.”

× Yes, I seen a bike can go to the park and take a bike.

✓ Yes, I have seen people ride bikes to the park.

原句中“a bike can go ... and take a bike”的结构不清楚：自行车不能自己“骑自行车”，而且 see 后直接接“a bike can ...”不符合这里的句子结构。可用“see + 人 + 动词原形”表达“看见某人做某事”，例如“see people ride bikes”。
