Bike— Part 1 채점 보고서

제안: 句子需要更自然和符合时态；少用重复词并增加简洁的细节。可以把双重否定与时态混用的问题修正为统一的过去时，去掉多余词汇，并给出简单原因或影响。建议练习使用一到两句话清楚回答，然后补充一两句细节。

예시: No, I didn't. My family couldn't afford a bike when I was a child, so I usually walked to school or borrowed my friends' bikes on weekends.

제안: 回答需要更流畅、语法准确并使用恰当的连接词。注意主谓一致（bikes are popular）、时态和去掉重复。提供具体原因或例子可以使回答更有说服力。建议用一到两句总述，再用一到两句具体原因或例子，并使用连接词如 'because'、'for example'。

예시: Yes, bikes are very popular in my country. Recently more people have taken up cycling for health and fitness because it's a cheap way to exercise; for example, many cities now have bike-sharing programs and dedicated cycle lanes.

× No, I didn't, and during my childhood my family can't, couldn't afford a bike.

✓ No, I didn't. During my childhood my family couldn't afford a bike.

问题类型：过去时错误（ID 5）。说明：原句混用了现在时的助动词“can't”和过去时“couldn't”，而句子谈论的是过去（my childhood），应使用过去时态。建议：删除“can't,”并把句子分为两句或用连词连接，确保使用过去时“couldn't”。例如："No, I didn't. During my childhood my family couldn't afford a bike."

× Yes, it is very popular in a recently and more and more people calls call for weight management so they choose to choose by bikes to do real exercise.

✓ Yes, they are very popular recently, and more and more people call for weight management, so they choose bikes to get real exercise.

问题类型：主谓一致/数一致（ID 27）以及其他相关问题。说明：原句用“it is”指代复数“bikes”不一致，应使用复数代词或复数动词“they are”。“in a recently”不合语法，正确为“recently”。“people calls”动词与复数主语不一致，应为“people call”。“choose to choose by bikes”重复且介词用法错误，应该是“choose bikes”或“choose to ride bikes”。建议：将主语与动词一致（bikes → they are），删除多余词，改正副词位置，使用正确动词形式。改写示例："Yes, they are very popular recently, and more and more people call for weight management, so they choose bikes to get real exercise."
