自行车— Part 1 评分报告

建议: 回答过于简短，缺乏信息量。应先用主题句直接回答，然后用1-2句具体细节支撑（例如谁买的、经常骑去哪、喜欢的原因或回忆），并使用连接词使表达连贯。注意控制在最多5句内。

示例: Yes, I did. My parents bought me a small red bike when I was six, and I often rode it to the park with my friends. Riding made me feel free and helped me build confidence, so it’s one of my fondest childhood memories.

建议: 回答包含断言但缺乏具体支持与逻辑衔接。应先直接回答（Yes/No），然后用1-2句解释原因并给具体例子（如城市共享单车、通勤或健身用途），使用连接词如“because”或“for example”。保持语言自然且不冗余。

示例: Yes, I think bikes are very popular in China because many people use them for short-distance travel and commuting. For example, bike-sharing schemes in cities have become widespread, making cycling a convenient and affordable option.

× Yes.

✓ Yes, I did.

原句只回答“Yes.” 在回答过去时的问句（Did you have...?) 时，应该使用助动词 did 加动词原形构成完整回答。更自然的简短肯定回答是“Yes, I did.” 建议在回答过去时问题时使用“Yes/No, did/didn't”加动词原形，或给出完整句子，例如“Yes, I had a bike when I was a child.”（注意：虽然题目要求只修正基于列出的语法类型，此处选择用“Yes, I did.”来与过去时问句一致。）

× Of course, I'm from China.

✓ Of course. I'm from China.

原句在回答“Do you think bikes are popular in your country?”时给出了与问题不直接相关的句子且缺少连贯性。应先直接回答问题（如“Yes, they are.”），然后补充国籍信息。若只想保留国籍信息，应用独立句并以句点分开。示例改为："Yes, they are. I'm from China." 建议在回答时先回应问题本身，再补充背景信息，保持句子结构清晰。
