Bike— Part 1 채점 보고서

제안: 回答直接，但“back”应为“bike”；“when I was a child”和“in my childhood time”意思重复，而且时态应使用过去时。可以先直接回答，再补充一个具体细节，例如自行车的颜色、用途或骑车的经历。

예시: Yes, I did. I had a small blue bike when I was a child, and I often rode it around my neighborhood.

제안: 先明确回答自行车是否受欢迎，再说明共享单车或个人自行车的情况。“back”应为“bike”，“sharing back”可改为“shared bikes”或“bike-sharing schemes”；“find them a sharing bike”表达不自然。建议用“because”连接原因，并举出具体场景。

예시: Yes, bikes are quite popular, especially shared bikes in cities. They’re easy to find on many streets, so people often use them for short trips or to get to a nearby bus or subway station.

× I have a back when I was a child in my childhood time.

✓ I had a bike when I was a child.

句子讲的是童年时期的经历，属于过去时间，因此动词 have 应使用过去式 had。

× Yes, I would say it depends, um, personally back or sharing back, because in my country we can find them a sharing bike everywhere in the street.

✓ Yes, I would say it depends. Personally, I think bikes and shared bikes are popular, because in my country we can find shared bikes everywhere on the streets.

这里需要用 shared 修饰 bike，表示“共享的自行车”。sharing 是现在分词，不能在这个表达中代替 shared。

× Yes, I would say it depends, um, personally back or sharing back, because in my country we can find them a sharing bike everywhere in the street.

✓ Yes, I would say it depends. Personally, I think bikes and shared bikes are popular, because in my country we can find shared bikes everywhere on the streets.

表示自行车在街上时，通常使用介词 on，表达为 on the street 或 on the streets；此处不应使用 in。
