Bike— Part 1 Báo cáo

Gợi ý: 回答过去的经历时要使用过去时。这里应说“Yes, I did”或“Yes, I had one”，而不是“Yes, I have”。可以再补充一个具体细节，例如自行车的颜色或你常骑车去哪里，让回答更自然、完整。

Ví dụ: Yes, I did. I had a small red bike, and I used to ride it around my neighborhood after school.

Gợi ý: 先直接回答问题，再用一两句补充原因或例子。注意主谓一致和时态：bikes是复数，且问题询问现在的情况，可以说“they are becoming more and more popular”或“they have become increasingly popular”。还可以具体说明人们骑车的原因。

Ví dụ: Yes, I think bikes are becoming more and more popular in my country. Many people ride them to work or school because they are affordable and convenient, especially in busy cities.

× Yes, I have.

✓ Yes, I did.

问题询问的是过去（when you were a child），回答应使用一般过去时的助动词 did。这里的 have 与问句中的 did 不一致。回答过去时的一般疑问句时，可用“Yes, + 主语 + did.”

× Yes, and it became more and more popular.

✓ Yes, and they are becoming more and more popular.

这里的 it 指代复数名词 bikes，因此代词应使用 they。回答时要让代词与所指名词的单复数一致。

× Yes, and it became more and more popular.

✓ Yes, and they are becoming more and more popular.

问句询问自行车现在是否受欢迎，回答应使用现在时。became 是一般过去时，不适合表达目前正在增加的趋势；可用 are becoming 表示这种变化正在发生。
