Bike— Part 1 채점 보고서

제안: 用更自然、简洁的句子直接回答问题，并注意时态和连贯性。避免重复表述和语法错误（例如"in that time"应为"at that time"；"I have my own bike until"应为过去时）。可先用主题句直接回答，然后用一两句补充细节并用连接词衔接。

예시: No, I didn't have a bike as a child. I couldn't ride because I had trouble keeping my balance, so my family never bought me one. I only got my first bike when I started university, after I learned how to ride.

제안: 回答总体不错，但要避免重复词（如两次使用"especially"）并用更地道词汇和连接词使表达更流畅。可以先给出直接观点，然后用具体例子支持，并说明原因或影响。注意简洁，不超过五句。

예시: Yes, bikes are very popular in China. Shared bike schemes are common on streets, at universities and near transit stations, which makes short trips very convenient. As a result, many people prefer cycling for quick, affordable travel in cities.

× Actually I didn't have a bike when I was a child because I couldn't ride a bike by myself in that time and it's hard for me to keep the balance.

✓ Actually I didn't have a bike when I was a child because I couldn't ride a bike by myself at that time and it was hard for me to keep my balance.

错误类型：过去时和短语用法。 解释：原句中用过去时描述童年经历是正确的，但短语“in that time”不地道，应改为“at that time”。此外，后半句使用现在时“it's hard for me”与前文过去时不一致，应改为过去时“it was hard for me”。另外“keep the balance”更常用“keep my balance”。 建议：使用一致的过去时态，將惯用短语替换为“at that time”，并将“the balance”改为“my balance”。

× So I have my own bike until I came to university and I learned how to ride a bike.

✓ So I didn't have my own bike until I came to university, when I learned how to ride one.

错误类型：过去时使用不当/句子结构错误。 解释：原句“So I have my own bike until I came to university”时态混用（现在时have与过去时间点until...came），应使用过去时“didn't have... until”。同时重复使用“bike”显得冗余，可用代词或“one”。为了连贯，加上“when”引导学习骑车的时间点。 建议：保持过去时一致，改为“didn't have... until I came to university”并用“when I learned how to ride one”。

× Yeah, cycling bicycles are really popular in China especially you can see many shared bike service on the street, especially in the university or some stations and I think it provides a really convenient and affordable choice for people.

✓ Yeah, bicycles are really popular in China. You can especially see many shared bike services on the streets, particularly near universities or at some stations, and I think they provide a very convenient and affordable option for people.

错误类型：形容词/副词用法与主谓一致、可数名词复数形式。 解释：’cycling bicycles‘重复且不自然，应该直接用“bicycles”或“bikes”。“shared bike service”为可数名词短语，指多项服务时需用复数“services”。“on the street”在此处更自然为复数“on the streets”或“near universities/at stations”。此外主语是复数“they”，动词应为复数“provide”，并把“choice”改为更常用的“option”。 建议：去掉冗余词，注意可数名词复数和主谓一致，使用更自然的短语如“shared bike services on the streets”并用“they provide a very convenient and affordable option”。
