Bike— Part 1 채점 보고서

제안: 回答过于简短且缺乏细节。应以主题句直接回答，然后用1-2句具体细节扩展（如什么时候得到的、在哪儿骑、频率或感受），并使用衔接词使表达连贯。注意语法和正式程度，避免口语化缩略形式过多。

예시: Yes, I had a bike when I was a child. I got it as a birthday present when I was eight and rode it almost every day around my neighborhood. Because it was lightweight and easy to handle, I felt very confident and often raced with my friends.

제안: 回答语法有误（主语与代词不一致）且内容简单。应直接回答并给出具体原因或例子（如通勤、环保、运动、基建），使用连接词增强逻辑。尽量用更丰富的词汇替代“popular”。

예시: Yes, bicycles are very popular in my country because many people use them for short commutes and exercise. For example, in cities there are dedicated bike lanes and bike-sharing programs, so cycling is a convenient and affordable option for daily travel.

× Yes, it is very popular.

✓ Yes, they are very popular.

错误类型为第三人称单数或主谓不一致（Third person singular issue / Subject-verb agreement）。句子中主语指代复数名词 “bikes”，应使用复数代词和动词。原句使用单数代词 "it" 和单数动词 "is"，与复数主语不一致。修改为 "they are" 来一致。改进建议：在代词和动词选择时先确认所指主体是单数还是复数，如果是复数（如 bikes），用 they 和 are；如果是单数（如 a bike），用 it/it is。
