Bike— Part 1 채점 보고서

제안: 回答过于简短，缺乏细节与连贯性。建议在开头直接回答后，用1-2句具体细节丰富内容（例如骑车的频率、用途、与谁一起、何时学会等），并使用连接词使句子更自然。例如可以描述场景和感受。注意句子不要超过5句。

예시: Yes, I did. I learned to ride when I was about five and used my bike almost every day to visit friends in the neighborhood. It was a small red bike with training wheels at first, and I remember feeling very proud when I could ride without help.

제안: 回答过于简单，缺乏论证与具体例子。建议先给出明确观点，然后用1-2句具体理由或例子支持（例如城市自行车道数量、人们使用自行车的场合、共享单车的普及等），并使用连接词如“because”或“for example”连接观点与细节。

예시: Yes, I think bikes are quite popular in my country because many cities have dedicated bike lanes and a widespread bike-sharing system. For example, commuters often use bicycles for short trips to avoid traffic and save money.

× Yes I did.

✓ Yes, I did.

这句原句在语法上没有错误，但在书写时应在 Yes 和后面的部分之间加逗号以符合英语书面习惯，且 I 前后需有空格。建议：口语中可以直接说“Yes, I did.”，书写时注意标点。

× Sure.

✓ Sure.

单词“Sure.”作为简短回答在口语中是可以接受的，语法上没有错误。若想更完整地回答问题，可以扩展为“Yes, they are popular.” 或 “Yes, I think so.” 建议用完整句子使表达更清晰。
