Bike— Part 1 채점 보고서

제안: 回答直接，结构清晰，也提供了颜色、礼物来源、骑车时间和感受等具体细节。主要问题是时态错误：应将“give”改为过去式“gave”，并将“as a birthday present”改为更自然的“as a birthday gift”或“for my birthday”。“a green bicycle”前面可以使用“a green bike”，避免重复；最后的定语从句较长，可以拆分或使用“so”使表达更自然。

예시: Yes, I did. I had a green bike, which my parents gave me for my birthday. I used to ride it with my friends every day after school, and it made me feel happy and free.

제안: 回答观点明确，并使用了“because”和“For example”来补充原因和例子，内容也与问题相关。主要问题是最后一句没有完成，导致答案不完整，影响流利度和连贯性；应补充完整的观点，例如说明骑自行车有利于健康或环保。另一个语法错误是“bike sharing service make”，应改为“bike-sharing services make”，因为主语是复数；“ride a bike to commute”可以改为更自然的“cycle to school or work”。

예시: Yes, I think bikes are quite popular in my country because they are convenient and affordable. For example, many people cycle to school or work to avoid traffic jams, while bike-sharing services make short trips easier. Moreover, cycling is environmentally friendly and helps people stay healthy.

× My parents give me as a birthday present and I used to ride it with my friend every day after school, which made me feel very happy and free.

✓ My parents gave it to me as a birthday present, and I used to ride it with my friend every day after school, which made me feel very happy and free.

这里描述的是童年时期发生的事情，应该使用一般过去时。give 的过去式是 gave。另外，give 后面需要说明“把什么东西给我”，因此补充代词 it，指代前面的 bike。

× For example, many people ride a bike to commute to school or work every day to avoid traffic jams and bike sharing service make cycling even easier for short trips.

✓ For example, many people ride a bike to commute to school or work every day to avoid traffic jams, and bike-sharing services make cycling even easier for short trips.

bike-sharing services 是复数主语，所以谓语应该使用复数形式 make。原句中的 service 是单数，但后面的 make 不与单数主语一致。建议先判断主语是单数还是复数，再选择 makes 或 make。
