Bike— Part 1 Báo cáo

Gợi ý: 回答基本切题，但“Yes, I am”时态和语法不正确。询问过去的经历时，应使用“Yes, I did”，并补充一两个具体细节，例如自行车的颜色、用途或骑车的地点。

Ví dụ: Yes, I did. I had a small red bike when I was about eight, and I used to ride it around my neighborhood.

Gợi ý: “Yes”直接回答了问题，但内容过于简短，没有解释原因或提供具体例子。建议先明确表达看法，再说明自行车受欢迎的原因，例如通勤方便、成本低或有助于锻炼。

Ví dụ: Yes, I think bikes are quite popular in my country, especially in cities. They’re an affordable and convenient way to get around, and many people also ride them for exercise.

× Yes, I am

✓ Yes, I did.

问题询问的是过去的经历（“Did you have… when you were a child?”），因此回答应使用过去时。这里用“am”是现在时，也不能与助动词“Did”对应。回答过去时的一般疑问句时，可以用“did”代替前面提到的动词短语，例如：“Yes, I did.”
