Bike— Part 1 채점 보고서

제안: 回答太简短且缺乏细节。应先直接回答，然后用1-2句补充细节（如为什么没有、有没有其他交通工具、儿童时期的活动），并使用连接词使话语更自然。注意完整句子和语法，例如使用“I didn’t have a bike”而不是单字回答。

예시: No, I didn’t have a bike when I was a child. My family couldn’t afford one at the time, so I usually walked or took the bus to school. As a result, I became quite used to walking long distances.

제안: 语法错误且表达不完整。应直接回答观点，然后用一到两句给出具体原因或例子，并使用连接词（because, so, for example）。注意主语和动词一致，例如“It’s popular in China because…”并提供具体细节如骑行文化、共享单车的影响等。

예시: Yes, I think bikes are very popular in China because of the rise of bike-sharing services and the convenience for short trips. For example, many people use shared bikes to commute to work or run errands, especially in big cities.

× Because are popular in China.

✓ Yes. They are popular in China.

问题类别（ID 26）：句子结构错误。原句缺少主语和完整的谓语结构；以“Because”开头但后面没有完成因果从句，且“are”缺少主语（如“they”）。改为“Yes. They are popular in China.”既回应了提问，又使用完整的主语+谓语结构，时态为一般现在，适用于描述普遍事实。建议：回答类似是否流行的问题时，可直接用“Yes/No”开头，然后用完整句子补充原因或说明；如果要用 because 引导原因从句，需写出完整的因果结构（例如：“Because bikes are convenient and affordable in China.”）。
