Bike— Part 1 채점 보고서

제안: 回答与问题不匹配：“No, I know”无法清楚表达你小时候有没有自行车。先直接回答“Yes”或“No”，再补充一个具体细节，例如你几岁时学会骑车，或为什么没有自行车。注意使用完整、自然的句子。

예시: No, I didn’t have a bike when I was a child. My family lived in a busy city, so I usually walked or took the bus instead.

제안: 先直接说明自行车在中国是否受欢迎；“a China country”和“So good”表达不自然，也没有清楚说明原因。可以补充具体用途或场景，例如通勤、短途出行或共享单车，并用“because”连接理由。

예시: Yes, bikes are quite popular in China, especially for short trips. Many people use shared bikes to get to work or to connect with public transport because they’re convenient and affordable.

× No, I know.

✓ No, I didn't.

问题问的是你小时候有没有自行车，使用一般过去时。回答否定时应使用 did 的否定形式 didn't，而不是一般现在时的 know。

× Yes, a China country. So good.

✓ Yes, bikes are popular in China. They are very good.

原回答中的 “a China country” 和 “So good” 都是缺少谓语动词的片段。回答自行车是否受欢迎时，可以补上主语和动词，说 “bikes are popular in China”；描述自行车时也应补全句子，例如 “They are very good”。
