Bike— Part 1 채점 보고서

제안: 主要问题是时态错误：因为“when I was a child”指过去，所以应将“have”改为过去式“had”。回答直接，但可以补充一个具体细节，例如自行车的颜色、使用场景或骑车带来的感受，使答案更完整自然。

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

제안: 回答基本切题，但内容过于简短，缺少明确观点和支持细节。可以先直接说明自行车很受欢迎，然后使用“because”或“especially”补充原因、使用场景或具体人群，例如通勤、锻炼以及共享单车。

예시: Yes, bikes are quite popular in China, especially in large cities. Many people use them for short commutes because they are convenient, affordable, and environmentally friendly.

× Yes, I have a bike when I was a child.

✓ Yes, I had a bike when I was a child.

“when I was a child”表示过去的时间，因此主句也应使用一般过去时。动词“have”的过去式是“had”，不能使用现在时“have”。建议看到“when I was...”“when I was a child”等过去时间表达时，检查主句动词是否也使用过去式。
