Bike— Part 1 채점 보고서

제안: 句子自然且直接回答了问题，但可以更具体并增加少量细节以丰富内容。另外可使用连接词或时间词使表达更流畅。注意避免重复“bike/bikes”。建议用一到两句补充回忆或感受，保持总句数不超过五句。

예시: Yes, I had a bike when I was a child, and I often rode it with my friends after school. We would race along the riverbank every weekend, which made those days very memorable.

제안: 回答内容相关且有观点，但句子有轻微语法问题（时态和主谓一致），并且结尾不完整。建议用一到两句清晰表达变化的原因和影响，使用连接词（for example, because, so）并修正结尾，使陈述完整且更具体。保持不超过五句。

예시: Yes, bikes are very popular in my country and their use has increased recently. For example, the introduction of shared bike services has made short trips much easier and reduced traffic congestion in city centers.

× Yes, I had a bike when I was a child and I always rode bikes with my friends.

✓ Yes, I had a bike when I was a child and I always rode my bike with my friends.

错误类型：过去时/数量一致问题（过去时态本身正确）。问题在于名词复数/代词搭配不一致。原句中开头提到“I had a bike”（单数），随后用“rode bikes”将“bike”变为复数，语义不一致。建议将第二部分与前文一致改为“rode my bike”或把第一句改为复数形式“I had bikes”。简明建议：保持前后指代一致，若先用单数则后文用单数/所有格。

× Yes, bikes are very popular in my country and it's gaining more popularity nowadays.

✓ Yes, bikes are very popular in my country and they are gaining more popularity nowadays.

错误类型：主谓一致/代词指代问题（属现在时）。原句中主语是复数“bikes”，但随后用单数代词“it”，造成代词与先行词数不一致。建议将“it”改为“they”以匹配复数主语。简明建议：复数名词作主语时，代词应使用复数形式。

× In the past, people rode their own bikes, but now we have shared bikes across the streets and it makes it easier for people to travel to different spots and.

✓ In the past, people rode their own bikes, but now we have shared bikes across the streets, which makes it easier for people to travel to different spots.

错误类型：句子结构/连接词及不完整句（结构错误）。原句结尾以“and.”终止，句子不完整且连词使用不当。把并列句改为定语从句（which makes...）或完整的并列句都可，且删除多余的“and”。简明建议：避免句尾残句，若用“and”后需接完整并列成分；这里用“which”引导非限制性定语从句更自然。
