Bike— Part 1 채점 보고서

제안: 回答没有清楚表达是否拥有自行车；“back”可能是“bike”的拼写或发音错误。谈论童年经历时应使用过去时，例如“had”，并直接回答“有”或“没有”，再补充一个具体细节。

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

제안: 回答直接，但内容过于简短，而且“bikes”可能指自行车或摩托车，表达略显笼统。可以明确所指，并补充原因或具体场景；注意在“country”后加逗号，使表达更自然。

예시: I don’t think bicycles are very popular in my country, especially in large cities. Many people prefer public transport because it’s more convenient for commuting.

× When I was a child, I have a back.

✓ When I was a child, I had a back.

句子描述的是过去（“When I was a child”），所以表示“拥有”的动词 have 应使用过去式 had。建议先根据时间提示词判断时态，再选择相应的动词形式。
