Bike— Part 1 채점 보고서

제안: 语法错误较明显，时态不一致且句子结构简单。回答应直接用过去时并给出一到两句支持细节（如谁送的、什么时候常骑、印象）。注意不要超过五句并保持自然流畅。建议练习使用过去时的主题句并辅以具体细节和连接词。

예시: Yes, I had a bike when I was a child. My parents bought it for me on my seventh birthday, and I used to ride it to the park every weekend. It was bright red and made me feel very independent.

제안: 主谓不一致且表达不完整，应直接回答并提供具体原因或例子。使用连词（because, so, for example）来连接观点和细节，扩展为一到三句，保持词汇贴切如“popular, common, convenient”。

예시: Yes, I think bikes are very popular in my country because they are cheap and convenient for short trips. For example, many students and workers ride bicycles to avoid traffic and save money on transport.

× When I was a child, I have a bike.

✓ When I was a child, I had a bike.

问题类型：现在时态使用错误（应使用过去时）。句子开头有时间状语“when I was a child”，表示过去时间，谓语动词应使用过去时。原句使用了现在时“have”，与时间状语不一致。建议：看到过去时间标志（when I was a child / last year / in 2005等）时，把动词改为过去式，例如“had”。

× Yes, I think I are popular in my country.

✓ Yes, I think I am popular in my country.

问题类型：主谓一致错误（代词与动词不一致）。主语“I”应与动词“am”搭配，而原句用了“are”，这是复数或第二人称的形式，不适用于第一人称单数。建议：记住“I”后面用“am”；其他人称要对应正确的形式（he/she/it → is，you/we/they → are）。
