Bike— Part 1 채점 보고서

제안: 回答基本直接，但有明显的词汇和语法错误。“held a back”应改为“had/owned a bike”，“my brother have”应改为“my brother had/has”。可以补充一个具体细节，例如说明哥哥如何使用自行车，答案会更自然、更完整。

예시: No, I didn’t have a bike when I was a child, but my brother had one. He often rode it to school, and sometimes I borrowed it from him.

제안: 回答语法基本正确，但过于简短，只表达了观点，没有提供原因或具体例子。建议使用“because”或“especially”补充细节，例如说明自行车在学生、通勤者或健身人群中很受欢迎。

예시: Yes, I think bikes are quite popular in my country, especially among students and people who live in crowded cities. They are affordable, convenient, and a good way to avoid traffic.

× No, I never held a back but my brother have a back.

✓ No, I never had a bike, but my brother had a bike.

问题中的“have”是现在时，但题目询问的是童年时期的经历，因此应使用过去时“had”。另外，“held a back”不符合英语表达；这里应说“had a bike”，表示“有一辆自行车”。

× No, I never held a back but my brother have a back.

✓ No, I never had a bike, but my brother had a bike.

“my brother”是第三人称单数，描述过去的事情时，动词“have”的过去式应为“had”。“Had”同时也符合过去时要求，因此不能使用“have”。
