Bike— Part 1 Báo cáo

Gợi ý: 回答基本直接，但时态错误。问题询问过去经历，应使用一般过去时“had”，而不是现在完成时“have”。此外，答案过于简短，建议补充一个具体细节，例如自行车的颜色、使用场景或骑车的感受，并使用“because”或“so”等连接词使回答更完整。

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

Gợi ý: 回答虽然直接且语法正确，但只有一个词，缺少解释和具体内容。建议先明确表达观点，然后用“because”补充至少一个原因，例如自行车环保、方便、价格低，最后可以加入具体场景或人群，使答案更自然、更有信息量。

Ví dụ: Yes, I think bikes are quite popular in my country because they are affordable and environmentally friendly. Many people ride them to school or work, especially in areas with heavy traffic.

× Yes, I have.

✓ Yes, I did.

问题使用了现在完成时助动词“have”，但问题是一般过去时“Did you have...?”，因此回答也应使用过去时助动词“did”。正确回答是“Yes, I did.”。“Yes.”本身没有语法错误。
