Bike— Part 1 채점 보고서

제안: 回答太简短且缺乏细节。建议用主题句直接回答后，添加1–2句具体细节来丰富内容，例如说明原因、情感或一次相关经历。使用连接词（e.g. because, so, although）保持连贯。尽量不超过5句。

예시: No, I didn't. I never owned a bike because my family couldn't afford one when I was young. As a result, I often walked to school and sometimes borrowed my neighbor's bike on weekends.

제안: 回答有语法错误且内容过于简短。首先注意主谓一致和人称（应说“Yes, they are”或“Yes, they are popular”）。然后提供1–2句具体理由或例子来支持观点，使用连接词（for example, because, therefore）使答案更自然且信息丰富。

예시: Yes, they are quite popular, especially in cities. For example, many people use bicycles for short commutes because they are cheap and convenient, and there are dedicated bike lanes in several urban areas.

× Yes it does.

✓ Yes, they are.

学生回答的对象是复数名词“bikes”，因此代词应使用复数“they”；原句用“does”是用于第三人称单数动词助动词，和复数主语不一致。建议：当回答关于复数名词是否流行时，使用复数代词+适当的be动词（例如“Yes, they are.”）；练习辨认主语单复数并选择相应的代词和动词形式。
