Bike— Part 1 Informe

Sugerencia: 回答过去经历时要用过去时态：“Yes, I did.” 第二句有明显的口误或修改痕迹（“a boat, a bike”），建议直接说“bought me a bike”。还可以补充一个具体细节，例如你常在哪里骑车或骑车的感受，让回答更完整、自然。

Ejemplo: Yes, I did. My father bought me a bike for my seventh birthday, and I used to ride it around our neighborhood after school.

Sugerencia: 回答切题，也给出了原因和例子，但最后一句没有说完，影响表达完整度。注意“choose bike”应改为“choose bikes”或“choose to ride a bike”。请补全通勤者如何使用自行车的例子，并用完整句子收尾。

Ejemplo: Yes, I think bicycles are quite popular in my country, especially in big cities. Many people choose to ride bikes when traffic is heavy because cycling is faster for short trips and cheaper than driving. For example, some commuters cycle to the nearest subway station and ride the train for the rest of their journey.

× Yes, I have.

✓ Yes, I did.

问题问的是你小时候是否有自行车，属于过去的情况，因此回答时要用一般过去时。这里用助动词 did 代替问句中的 did；have 不符合过去时问句的时态。

× Many people choose bike when traffic is heavy because cycling is faster for short trips and cheaper than driving.

✓ Many people choose a bike when traffic is heavy because cycling is faster for short trips and cheaper than driving.

bike 是可数名词单数，前面不能单独使用，需要加冠词。这里可以说 a bike，表示选择骑一辆自行车。
