Bike— Part 1 Informe

Sugerencia: 回答直接且语法正确，但内容较短。可以补充一个具体原因或相关经历，例如当时如何出行、是否向朋友借过自行车，让回答更自然、更有信息量。

Ejemplo: No, I never had a bike when I was a child. My parents usually drove me to school, and I sometimes borrowed a friend's bike to ride around the neighborhood.

Sugerencia: 回答回应了问题，但“popular”重复使用，且“and so on”比较笼统。可以改用“large cities”等更准确的表达，并补充自行车受欢迎的原因或具体用途，使观点更清楚。

Ejemplo: Yes, I think bikes are quite popular in large cities such as Shanghai and Beijing. Many people use them for short trips because they are convenient and help them avoid traffic.
