Bike— Part 1 채점 보고서

제안: 句子结构和时态需要改进。首先要用一句话直接回答（topic sentence），然后用一两句具体细节支持。注意过去时的一致性（teach → taught），并用连词使表达更连贯。可以补充骑车的年龄、地点或感受来丰富内容，但不要超过5句。

예시: Yes, I did. I learned to ride when I was seven, and my older brother taught me in our neighborhood park. I remember he held the bike at first and ran beside me until I felt confident enough to ride alone.

제안: 回答不够清晰且语法不正确。首先给出直接的观点，然后用具体理由支持。避免断裂的句子，使用合适的连接词（for example, because, so）并注意词序与搭配（ride motorcycles / use motorcycles）。可以提供比较或例子说明摩托车更普及。

예시: Not really. Motorcycles are much more common in my country because they are faster and cheaper to run. For example, most people use scooters to commute to work, especially in crowded cities.

× Yes, and my brother teach me how to ride a bike.

✓ Yes, and my brother taught me how to ride a bike.

问题类型：过去时错误（ID 5）。说明：句子在描述过去发生的动作（小时候学骑自行车），主句应使用过去时。原句中动词“teach”是现在时，需改为过去式“taught”。建议：在描述过去发生的事情时，把主要动词改为过去式，例如 “taught”。

× No, because everyone is. Ride the motorcycle in the way.

✓ No, because everyone rides motorcycles that way.

问题类型：句子结构错误（ID 26）并包含第三人称单数和名词复数问题。说明：原句“everyone is. Ride the motorcycle in the way.” 结构不完整且断开。“everyone”作为主语意指“每个人”，谓语应为第三人称单数形式“rides”；“motorcycle”在泛指多数人骑摩托车时应使用复数“motorcycles”；“in the way”用法不自然，应改为“that way”表示“那种方式”。建议：将句子合并为一个完整句子并使用正确的主谓形式和复数名词，如 “everyone rides motorcycles that way”。
