Bike— Part 1 채점 보고서

제안: 句子时态与用词不准确，且语句重复，回答过于简短且缺乏细节。建议：用恰当时态区分过去与现在，避免重复，并补充1–2个具体细节（例如什么时候开始骑、谁教的、喜欢哪类骑行）。使用连接词使表达更连贯。

예시: Yes, I had a bike when I was a child. I started learning to ride when I was about six, and my father taught me. Nowadays I also own a road bike that I use for weekend rides, because I enjoy exercising outdoors and exploring nearby trails.

제안: 回答总体清晰但过于笼统且细节不足。建议：先给出直接观点，然后用连接词（e.g., because, for example）补充具体原因或例子，如城市通勤、环保或政府推行自行车道等，扩展到2–3句。

예시: Yes, I think bikes are very popular in my country because they are cheap and convenient for short journeys. For example, many children ride to school, and in cities a lot of people cycle to work thanks to more bike lanes and parking facilities.

× Yes I do.

✓ Yes, I did.

这句回答的时间点是过去（当你还是孩子的时候），因此动词时态应使用一般过去时。原句“Yes I do.”使用了一般现在时，与问题的过去时态不一致。建议将“do”改为过去式“did”，并在“Yes”和“I”之间加逗号以符合书面习惯。

× I I had a bike when I was a child and now I even had a road bike.

✓ I had a bike when I was a child, and now I even have a road bike.

过去与现在对比时需要在从句和主句使用不同的时态。句子开头重复了“I I”，属于笔误需要删除。句中“now”表示现在时，因此应使用一般现在时“have”而不是过去式“had”。建议删除重复的“I”，并把“had”改为“have”，在并列句中用逗号和连接词“and”。（语法问题类型：5 过去时问题）

× I like riding.

✓ I like riding bikes.

原句“I like riding.”虽然语法上可以接受，但句意不够明确。根据上下文最好补上宾语“bikes”以明确指代。此处为一般现在时描述习惯性动作，应使用一般现在时态。建议在动词后加上宾语以使表达清晰。

× Yeah, of course.

✓ Yes, of course.

这句是简短寒暄，语法本身无明显错误，但在正式考试语域中用“Yes”比“Yeah”更合适，且与后文时态无冲突。建议将口语化“Yeah”改为更正式的“Yes”。

× I've seen many kids nowadays riding their bikes, going to school and back home.

✓ I've seen many kids nowadays riding their bikes, going to school and coming back home.

原句“going to school and back home”中“back home”缺少动词，造成结构不平行。为保持平行结构，应在并列动词短语中使用相同的形式，加入“coming”以与“going”对应。时态“I've seen”使用现在完成时描述最近观察，保持不变。
