Bike— Part 1 채점 보고서

제안: 回答时态和形式不准确，句子太短且缺乏细节。建议用过去时直接回答并补充一两句具体细节，例如什么时候有、是什么样的自行车、是否常骑等。注意句子不超过5句并使用连接词使表达更连贯。

예시: Yes, I did. I had a small red bike when I was about seven, and I used to ride it to visit my friends after school. It was simple but reliable, so I rode it almost every day.

제안: 主语与代词使用不当，而且断言“everybody can ride a bike”太绝对且缺乏证据。建议给出更具体的程度描述并提供原因或例子，用连接词（for example、because等）使答案更有逻辑。保持不超过5句。

예시: Yes, they are quite popular, especially in cities. Many people use bicycles for short trips because they are cheap and convenient. For example, you can see students and office workers cycling to work during rush hour.

× Yes, I have.

✓ Yes, I did.

学生在回答关于过去是否拥有自行车的问题（Did you have...?）时，应使用过去时。原句“Yes, I have.”使用现在时助动词have/has，时态不匹配。正确用法是“Yes, I did.” 或 “Yes, I had one.” 建议：回答过去发生的事情时，把动词改为过去时（did / had）。

× Yes, it is. Everybody in my country can ride a bike.

✓ Yes, they are. Everybody in my country can ride a bike.

考官问的是“Do you think bikes are popular...?” 主语是复数“bikes”，所以代词指代也应为复数“they”而不是单数“it”。原句“It is”使用了单数代词，造成代词与先行词数不一致。建议：用复数代词“they”来指代复数名词bikes；确保代词与所指名词在人称和数上一致。
