Bike— Part 1 채점 보고서

제안: 回答时时态使用不当且过于简短，缺乏细节支持。应使用过去时并给出简短原因或背景，使用连接词使回答更自然连贯。建议在一句主题句后补充1–2句具体细节（例如原因、时间或影响）。

예시: No, I didn't have a bike when I was a child. My family lived in a busy city where streets were crowded, so my parents preferred I walk or take public transport. As a result, I only learned to cycle much later, when I was a teenager.

제안: 回答较自然但太简短且用词略单一（tool不太恰当）。可以先直接回答，然后用连接词补充具体原因、场景或比较，使用更恰当的词汇如 "transport" 或 "mode of transport" 并给出例子来丰富内容。

예시: Yes, I think bikes are quite popular in my country because they are an inexpensive and flexible mode of transport. For example, many people use electric bikes to commute short distances, especially in crowded urban areas, and cycling is also common for shopping and short errands.

× No, I haven't.

✓ No, I didn't.

学生的回答针对考官过去时的问题“Did you have a bike when you were a child?”应该使用一般过去时。使用“haven't”是现在完成时的缩写形式，且形式与助动词选择不匹配；正确的否定回答为“didn't”后接动词原形（如果需要说明拥有，则是“didn't have”或简略为“no, I didn't”）。建议：遇到以“Did”开头的问句，用一般过去时回答，如“I did”/“I didn't”或“I had”/“I didn't have”。

× Yeah, it's a convenient tool in our daily life.

✓ Yeah, they're a convenient means in our daily lives.

原句用“it's”指代bikes（复数），主谓不一致。且“tool”虽可用，但常说“means”或“transportation”更自然；“daily life”在表示一般的日常生活时常用复数形式“daily lives”。建议：当主语为复数（bikes）时，谓语和代词也应使用复数形式（they, are）；尽量用符合语境的名词并注意名词单复数一致。
