Bike— Part 1 채점 보고서

제안: 回答直接且语法正确，但内容过短，没有解释原因或补充相关细节。可以补充你小时候是否想要自行车、平时如何出行，或后来有没有学会骑车；控制在两到三句即可。

예시: No, I didn’t have a bike when I was a child. My parents thought it wasn’t very safe for me to ride one, so I usually walked or took the bus instead.

제안: 回答切题且表达正确，但只给出了简单肯定，没有说明自行车为什么受欢迎或人们通常在哪里使用。可以补充一两个具体原因，例如通勤方便、节省开支或有利于环保，并举出常见使用场景。

예시: Yes, I do. Bikes are quite popular, especially in crowded cities, because they’re affordable and convenient for short trips. Many people also use them to commute or get some exercise.
