Bike— Part 1 Báo cáo

Gợi ý: 回答直接但过于简短且重复（使用了 did have 的冗余结构）。建议用一到两句扩展细节，说明什么时候开始、有无特别记忆或用途，并用更自然的表达（例如 I had a bike / I used to have a bike）。注意句子不宜超过5句。

Ví dụ: Yes, I had a bike when I was a child. I got it when I was about seven and used to ride it to my friend’s house every afternoon; I remember fixing a flat tyre once and feeling very proud.

Gợi ý: 回答清晰且包含具体场景，但可以更自然并加入连接词和比较或原因来丰富内容。建议补充具体例子或比较（如与公共交通或 cars 的对比），并用更口语化表达以显得自然。保持不超过5句。

Ví dụ: Yes, bikes are very popular in my country, especially in cities and rural areas because they are affordable and convenient. For example, many people cycle to work in the morning to avoid traffic, while in villages bikes are often used to carry goods to the market.

× Yes, I did have a bike when I was a child.

✓ Yes, I did have a bike when I was a child.

该句语法正确，无需修改。句子使用过去时询问童年时是否有自行车，回答用助动词 did 加动词原形表强调过去事实，结构和时态均正确。

× Yes, bicycles are quite popular in my country, especially in cities and rural areas where they serve as an affordable and efficient mode of transport.

✓ Yes, bicycles are quite popular in my country, especially in cities and rural areas where they serve as an affordable and efficient mode of transport.

该句语法正确，无需修改。主句使用现在时描述普遍事实（bicycles are quite popular），后面的定语从句和短语（where they serve as an affordable and efficient mode of transport）结构完整，词序和用词恰当。
