Bike— Part 1 Báo cáo

Gợi ý: 你直接回答了问题，但第一句重复了“when I was a child”，第二句“I have a back”表达不清楚，可能是想说“I had a bike”。注意用过去时描述童年经历，并补充一个具体细节，例如你在哪里骑车或骑车做什么。

Ví dụ: Yes, I did. I had a bike when I was younger, and I often rode it around my neighborhood.

Gợi ý: 回答明确且语法基本正确，但只是重复题目中的“popular”和“country”，缺少原因或具体细节。可以补充一种观察或原因，例如人们更常使用什么交通工具。注意根据实际情况说明原因。

Ví dụ: No, I don't think bikes are very popular in my country. Many people prefer to travel by car or public transport, especially when they need to cover long distances.

× I have a back.

✓ I had a back.

句子描述的是小时候的情况，属于过去时间，因此应将一般现在时的“have”改为一般过去时“had”。注意：“back”在这里可能是词汇误用，但词汇问题不属于给定的语法问题类型，因此未作修改。
