Bike— Part 1 채점 보고서

제안: 回答要更直接并保持简洁，避免冗长和语法不准。开头应直接回应问题（如“Yes, I did.”或“No, I didn't.”），然后补充一到两句具体细节。注意语法（例如“learned to ride a bike through it”不自然，应改为“learned to ride it”或“learned to ride a bike”），并使用连接词如“so”或“then”使句子更连贯。

예시: Yes, I did. I envied kids who had their own bikes, so one day my parents bought me one. I practiced in the park and soon learned to ride it by myself.

제안: 回答需更准确、流畅并提供具体细节或例子。避免语法错误（例如“used to riding by shared bikes on”应为“used to riding shared bikes”或“often ride shared bikes”），并避免重复（如“many, many”）。组织回答可用一两句主句加一两句支持细节，使用连接词如“because”或“for example”。

예시: Yes, bikes are very popular. Many people often use shared bikes for short trips because they are convenient and cheap. For example, young people frequently cycle to work or school, especially in busy cities.

× When I was a child, I envied other kids for having their own bicycles until one day I also got one and learned to ride a bike through it.

✓ When I was a child, I envied other kids for having their own bicycles until one day I got one too and learned to ride it.

句子结构不清、短语使用不当。“also got one and learned to ride a bike through it” 带来歧义且不自然。应将 'also' 放在 'got one' 后用 'too' 更口语化，且把 'learned to ride a bike through it' 改为 'learned to ride it'，直接指代那辆自行车，语义清楚。建议把句子拆分或调整词序以保持主句与时间状语的清晰关系。

× Of course, many people used to riding by shared bikes on.

✓ Of course, many people are used to riding shared bikes.

原句 'used to riding by shared bikes on' 时态和介词使用错误。'used to' 后接动名词时应为 'be used to doing' 表示习惯，且不需要 'by' 或句末 'on'。正确结构为 'are used to riding shared bikes'。建议记住 'be used to + -ing' 表示习惯。

× Of course, many people used to riding by shared bikes on.

✓ Of course, many people are used to riding shared bikes.

原句中出现多余或错误的介词 'by' 和句尾的 'on'。在英文中表达“习惯于骑共享单车”应使用 'be used to riding' 并直接跟宾语 'shared bikes'，不加 'by' 或 'on'。

× Besides, many, many young people also like to ride bike.

✓ Besides, many young people also like to ride bikes.

名词单复数与动词搭配问题。'many young people' 是复数，因此动词 'like' 正确，但可数名词 'bike' 在泛指复数时应使用复数 'bikes'。此外，句中不需双重 'many, many'，去掉重复更自然。建议使用 'ride bikes' 或 'ride a bike'（若指个体习惯）。

× For.

✓ (删除) 或者改为完整句： 'For example, they find it convenient and cheap.'

单独的 'For.' 不是完整句子，属于句子结构错误（缺乏谓语或上下文）。应删除或补充为完整句子以表明举例或说明原因。建议写出完整的原因句，例如 'For example, it is convenient and cheap.'
