Bike— Part 1 채점 보고서

제안: 回答直接，但只有一个词，缺少展开。可以补充一个具体原因或童年时的出行方式，让回答更自然完整；通常再加一两句即可。

예시: No, I didn’t have a bike when I was a child. My family usually drove me to school, and I played sports with my friends instead.

제안: “I don’t know”没有直接回应题目，也没有解释。可以先给出大致判断；如果不确定，可以说明原因，再补充一个观察到的例子。

예시: Yes, I think bikes are quite popular in my country, especially in cities. Many people use them for short trips because they’re convenient and inexpensive.
