Bike— Part 1 Informe

Sugerencia: 注意过去时态：问题询问童年经历，应将“do have”改为“had”。回答直接回应了问题，但可以补充一两个具体细节，例如自行车的颜色、骑车的地点或用途，让回答更自然、完整。

Ejemplo: Yes, I had a bike when I was a child. It was a small red one, and I often rode it around my neighbourhood after school.

Sugerencia: 回答切题且语法基本正确，但“popular”和“commonly seen”意思重复。可以保留其中一个表达，再补充具体原因或例子，例如人们骑车通勤、锻炼，或在城市里使用共享单车。

Ejemplo: Yes, bikes are quite popular in my country. Many people use them for short trips because they’re convenient and inexpensive, and shared bikes are easy to find in cities.

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

✓ Yes, I had a bike when I was a child.

句子中的“when I was a child”表明这件事发生在过去，因此主句也应使用过去时。这里的“do have”是现在时形式，应改为过去式“had”。回答关于过去经历的问题时，注意让动词时态与时间表达保持一致。
