Bike— Part 1 채점 보고서

제안: 句子时态和语法有误，表达不够自然且冗长。回答应直接且简洁地回应问题，先给出主题句，然后用一两句具体细节做支持。注意使用正确的过去时（had/couldn't）和更地道的表达（couldn't keep my balance / my parents didn't buy me one）。可用连接词简洁衔接原因。

예시: No, I didn't have a bike as a child. I couldn't keep my balance well, so I wasn't able to ride safely, and my parents decided not to buy one for me.

제안: 回答不完整且有语法和连贯性问题。应给出完整主题句，并用清晰的支持细节解释原因，使用连词（because, however）保持逻辑。注意主谓一致（my country has）和完整句子结构。可以补充一两个具体例子（如地铁、公交更方便）。

예시: Not really. In my country, public transportation has improved a lot, so many people prefer buses and metro for commuting. As a result, fewer people rely on bicycles for daily travel.

× No, when I was a child I have no ability of balance, so I can't control the bike so that my parents didn't buy a bike to me.

✓ No. When I was a child I had no sense of balance, so I couldn't control a bike, and my parents didn't buy one for me.

问题类型：现在时使用不当（应使用过去时）。句子中描述的是过去的情况，应全部用过去时。具体错误包括："I have" 应为过去式 "I had"；"I can't control"（现在时、否定简写）应为过去时 "I couldn't control"；逻辑连词使用不自然，"so that" 用法不正确，改为并列连接词 "and"。此外建议把 "ability of balance" 改为更地道的表达 "sense of balance"，把 "buy a bike to me" 改为 "buy one for me"。建议：遇到谈论过去经历时，动词统一用过去时；使用更自然的词组（sense of balance, buy one for someone）。

× Not really because my country have. A. Developing public transportation so we don't.

✓ Not really, because my country has a developing public transportation system, so we don't.

问题类型：主谓一致（以及句子结构错误）。原句中主语 "my country" 是单数，动词应为第三人称单数形式 "has" 而非 "have"。句子断断续续且标点混乱，"A. Developing" 不符合书面表达，应连成完整短语 "has a developing public transportation system"。最后的 "so we don't" 不完整，需补足上下文，这里保留为 "so we don't"（不怎么骑自行车）但在正式表达中可改为 "so people don't often ride bikes"。建议：检查主语单复数，保证句子完整连贯，使用正确标点。
