Bike— Part 1 Informe

Sugerencia: 句子时态和一致性需要改进，避免重复并更自然地表达时间范围。回答应包含主题句并用一到两句补充细节。可以把时态统一为过去时，精简重复信息，并用连词使表达更流畅。

Ejemplo: Yes. I got my first bike when I was five and kept it until I was ten because it became too small for me. I learned to ride it in the park near my house and rode it almost every day during summer, which helped me gain confidence and independence.

Sugerencia: 句子连贯性和用词需要改进，避免语法错误和笨拙表达。先给出直接回答，再用一到两句具体细节支持（例如使用场景、优势或统计）。使用连接词如 'also' 或 'for example' 来增强逻辑。

Ejemplo: Yes, I think bikes are very popular in my country. Many people own private bikes for daily commuting, and there are also bike-sharing services — you just scan a QR code to unlock a bike, which is very convenient for short trips around the city.

× Yes, I had a bike when I was five years old and I owned it until I'm 10 years old because the bike was too small for me when I am 10 years old.

✓ Yes, I had a bike when I was five years old and I owned it until I was 10 years old because the bike was too small for me when I was 10.

错误类型：过去时错误（ID 5）。原句中混用了现在时和过去时，句子开头用过去时“had”“owned”，但接着使用现在时“I'm”/“am 10 years old”，时态不一致。应保持整个叙述在过去时，改为“was 10 years old”。另外结尾重复表述“when I was 10 years old”可以简化为一次。建议：在叙述过去发生的事情时，全句使用过去时，避免在同一叙述中混入现在时。

× Yes, of course, in our country many people have their own bikes.

✓ Yes, of course. In our country, many people have their own bikes.

错误类型：现在时问题/句子结构（ID 6 可兼作 26）。原句语法本身时态正确（现在时），但缺少适当的标点导致阅读不流畅。建议：保持现在时描述普遍事实，同时注意句子分割与标点，使表达更清晰。

× Also in a country we have shared bikes, you can only scan the QR and then you can rent it for a while.

✓ Also, in my country we have shared bikes; you can simply scan a QR code and then rent one for a while.

错误类型：句子结构错误（ID 26）和冠词/指示词使用不当（可对应 ID 22/17）。原句中“in a country”表达不明确，应为“in my country”；“scan the QR”不自然，常用表达是“scan a QR code”；代词“it”与先行词不一致，应使用“one”指“a bike”。此外句子为并列句，使用分号或分句更清晰。建议：使用明确的指示词（my country），说“a QR code”，用“rent one”代替“rent it”，并注意句子连接。
