Bike— Part 1 채점 보고서

제안: 用更直接且时态正确的句子回答问题，控制在不超过5个句子，提供一到两个具体细节，并使用连接词使表达连贯。例如说明什么时候有、谁给的或学会骑车的经历。注意语法（例如过去时）和词汇的准确使用。

예시: Yes, I had a bike when I was a child. It was a small red bicycle that my parents bought me for my eighth birthday, and I spent many afternoons practicing in the park. Because I rode it so often, I became quite confident and independent.

제안: 回答应更精确并使用正确语法，先给出直接观点，然后用一两个具体例子或原因支持观点。使用连接词（e.g., because, for example）来增强逻辑性，注意时态和动词形式。

예시: Yes, bikes are still very popular in China, especially in cities and on university campuses. For example, when I started university I often cycled to class because it was cheap and convenient, and it also helped me stay fit.

× Yes, I have a background with a child and I love riding a bike and I also spend a lot of time practicing how to ride a bike and I have a great fun.

✓ Yes, I had a bicycle when I was a child. I loved riding it, and I spent a lot of time practicing how to ride a bike. It was great fun.

问题类型：现在时使用不当（ID 6）。原句在回答过去是否拥有自行车时用了现在时“have / love / spend / have”，应与问题的过去时间一致使用过去时。建议：将句子中的动词改为过去时（have→had，love→loved，spend→spent），并把“a great fun”改为惯用表达“great fun”。此外将冗长句分为短句，语义更清晰。

× When I graduated from high school, I always riding a bike to go to study in university and I think it's very fun and also can build myself up.

✓ When I graduated from high school, I always rode a bike to go to university to study. I thought it was very fun and it also helped build me up.

问题类型：动词 -ing 形式使用不当（ID 8）及过去时使用（ID 5/6）。原句中“always riding”缺少助动词或正确时态，应使用过去时“always rode”。后半句时态应与时间点一致，改为过去时“thought / helped”。另外“go to study in university”表达冗长，改为惯用搭配“go to university to study”；“build myself up”更自然的过去时为“helped build me up”。建议：把动词改为过去式并使用自然搭配，句子清晰分开。
