Bike— Part 1 Informe

Sugerencia: 回答直接且语法基本正确。可以加入一个具体细节，例如自行车的颜色、使用场景或它带来的感受，使答案更丰富。注意使用更自然的表达，如“when I was in primary school”后面可以补充“my parents bought me”。

Ejemplo: Yes, I had my first bike when I was in primary school. It was a small blue bike that my parents bought me for my birthday. I often rode it around my neighborhood with my friends, so it was a very memorable part of my childhood.

Sugerencia: 回答没有直接充分说明“在你的国家是否流行”，而且存在语法和搭配问题：“both my friend and I have bikes”应改为“both my friends and I had bikes”或“my friends and I all had bikes”。建议先明确回答，再说明普及的原因或举例；同时注意过去时与复数形式。

Ejemplo: Yes, bikes are quite popular in my country, especially among children and young adults. When I was young, my friends and I all had bikes, and we often rode them to school or around our neighborhood. Nowadays, many people also use bicycles for exercise and commuting.

× Yes, when I was young both my friend and I have bikes.

✓ Yes, when I was young, both my friend and I had bikes.

“when I was young”描述的是过去的时间，因此后面的动词也应使用一般过去时。原句中的“have”是一般现在时，应改为过去式“had”。另外，在时间状语“when I was young”后加逗号，可以使句子结构更清晰。建议看到“when I was a child/young”这类过去时间表达时，检查主句动词是否也使用过去时。
