Bike— Part 1 Report

Suggestion: 你的回答过于简单且重复，缺乏信息量和结构。建议给出主题句并补充1–2个具体细节，例如什么时候有自行车、谁送的、骑车的频率或一次难忘的经历。使用连接词使句子连贯。

Example: Yes, I did. I got my first bike when I was seven as a birthday gift from my parents, and I rode it to school almost every day. Although I fell a few times at the beginning, I quickly learned to balance and loved exploring the neighborhood.

Suggestion: 你的回答太简短且没有理由或例子。建议先给出直接回答，然后用1–2个原因或具体例子支持你的观点，例如城市共享单车、通勤习惯或休闲骑行场景，使用连接词如“because”或“for example”。

Example: Yes, I think bikes are very popular, mainly because many people use shared bikes for short commutes and errands. For example, in big cities you can often see commuters and students riding bikes to avoid traffic and save money.

× Yes, yes, yes, yes.

✓ Yes, I did.

学生的回答重复“yes”四次属于句子结构和礼貌表达问题（对应列表中的“Sentence structure errors”）。在回答过去时的提问“Did you have a bike when you were a child?”时，应使用完整简洁的句子，例如“Yes, I did.” 这样既语法正确又礼貌。建议使用主语+助动词+动词原形的结构来回答一般过去时的问句，避免无意义的重复。

× Yeah, of course.

✓ Yes, of course.

虽然“Yeah, of course.”在口语中常见，但在正式测试中应优先使用标准形式“Yes”而非非正式的“Yeah”。这属于句子结构/用词风格问题（对应“Sentence structure errors”）。建议在正式场合用“Yes, of course.” 来保持礼貌与规范。
