Bike— Part 1 채점 보고서

제안: 回答缺乏条理且有语法错误，表达不自然。首先要直接回应问题（有或没有），然后用1–2句具体原因或细节支持，句子要完整并使用连接词，避免口语填充词（like, you know）。也要注意时态一致（过去时）。例如可以先说“I didn't have one until I was 14.” 再补充为什么，以及一两个具体细节。

예시: I didn't have a bike until I was 14. I was quite shy and not very adventurous as a child, so I avoided sports and outdoor activities. As a result, my parents never bought me one, and I only started cycling when many of my friends learned to ride.

제안: 回答比较直接但表达重复且语法和用词不够准确。应先给出清晰的主句，然后用连词（for example, especially, because）给出具体场景和原因，避免重复短语。可补充一些具体数据或对比以增加内容丰富度。注意单复数和搭配（bikes are everywhere / shared bikes are especially common）。

예시: Yes, bikes are very popular in my country. For example, you can see them everywhere on the streets and on university campuses, and shared-bike services have made cycling even more common. Many people choose bikes because they are cheap, convenient and good for short trips.

× Actually, I don't have a bike until I was 14.

✓ Actually, I didn't have a bike until I was 14.

句子描述过去的情况，应该使用过去时。原句用的是现在时的否定（don't have）与过去时间点（was 14）不一致。改为过去式 did not have（缩写 didn't have）以保持时态一致。建议：描述过去发生的事情时，统一使用过去时态。

× Worse or so.

✓ Something like that.

原句片段“Worse or so.” 结构不完整，不能独立表达明确含义。常见口语里会用“Something like that”或“Or something like that”来表示“差不多是那样/类似的”。建议：将不完整片段改为完整短语以便清楚表达。

× Yeah, 'cause, you know, I was not too brave to try the new things when I was so young, especially in the sports.

✓ Yeah, 'cause, you know, I wasn't brave enough to try new things when I was so young, especially in sports.

句中存在多处问题：1) “was not too brave” 更自然的表达是“wasn't brave enough”表示“不够勇敢”；2) “the new things” 中的定冠词不必要，直接用“new things”；3) “in the sports” 中“the”不需要，且通常说“in sports”。这些改动保持了过去时并使表达更地道。建议：用“wasn't brave enough + to do”结构，去掉不必要的冠词。

× You know, I'm an introvert, so I'm not good at doing like.

✓ You know, I'm an introvert, so I'm not good at things like that.

原句“not good at doing like”不完整且语法不正确。英语中表达“不擅长类似的事情”常用“not good at things like that”或“not good at doing things like that”。建议：补全短语，使用固定搭配“not good at + noun/gerund”。

× I think it's very popular, especially in the street, in the campus, almost everywhere you can go, you can see a lot of bikes there as a pedestrian or a passenger.

✓ I think they're very popular, especially on the streets and on campus; almost everywhere you go, you can see a lot of bikes, whether as a pedestrian or a passenger.

原句存在时态和主谓一致问题：主语指复数“bikes”，故谓语应为复数形式“they are/they're”。另外介词搭配应为“on the streets/on campus”，并省略多余的“there”。建议：将单数形式“it's”改为复数“they're”，调整介词和句子结构以更自然表达。

× Bikes out everywhere, especially the shared bike.

✓ Bikes are everywhere, especially shared bikes.

原句“Bikes out everywhere”缺少谓语，应补上“are”。“the shared bike”要指共享单车，使用复数“shared bikes”更合适。建议：使用完整句子结构“Bikes are everywhere”，并保持名词单复数一致。
