Bike— Part 1 Relatório

Sugestão: 回答过于简短，缺乏细节与扩展。按评分规则，应先给出直接回答的主题句，然后用一到两句具体细节支持，例如解释原因、描述感受或举例，同时保持自然与连贯。可以使用连接词（例如because、so、when）来组织句子。尽量控制在不超过5句且避免冗余。

Exemplo: No, I didn't have a bike when I was a child. My family couldn't afford one, so I usually walked to school or took the bus. I sometimes borrowed my neighbor’s bike on weekends, which made me wish I had my own.

Sugestão: 回答含糊且不自然，仅有一个词并且有犹豫声音。应先给出直接明确的主题句，然后用一到两句具体支持内容，例如描述城市骑行情况、常见使用场景或比较其它交通工具。使用连词（for example, because）使回答更连贯，并扩展细节以显示词汇范围。

Exemplo: Yes, I think bikes are quite popular in my country. Many people use them for short trips and commuting in cities because they are cheap and convenient, and bike-sharing schemes have also become widespread in recent years.

× Student: No, I didn't have a bike.

✓ No correction needed.

该句“No, I didn't have a bike.”在语法上与问题时态（过去）和含义完全匹配，无需修改。

× Student: MMM, yes.

✓ No correction needed (informal hesitation ‘MMM, yes’ is acceptable in spoken dialogue).

该句为口语中表示犹豫或思考的填充词（拟声词）后接肯定答复。虽然在正式书面语中应避免，但在口语测试中是可以接受的，且不属于列表中的任何语法错误类型，因此不作修改。
