Bike— Part 1 채점 보고서

제안: 回答太簡短且未直接擴展內容。應以主題句直接回應並補充一兩個具體細節（例如為何沒有、是否有其他代步工具或童年活動），並使用連接詞保持語意流暢。保持不超過五句。

예시: No, I didn’t have a bike when I was a child because my family lived in a crowded city without safe cycling paths. Instead, I usually walked or took public transport to school, and I often played indoor games with my friends.

제안: 回答顯得不確定且沒有展開。應先給出直接立場（yes/no/partly），接著用一至兩個具體理由或例子支持觀點，使用連接詞如“because”或“however”。保持不超過五句。

예시: I think bikes are fairly popular in my country because many people use them for short commutes in cities, and bike-sharing programs have grown recently. However, in rural areas cars are more common due to longer distances.

× No.

✓ No, I didn't.

原句过于简短，缺少动词和时态信息。回答关于过去是否有自行车时，应使用过去时的完整句子，例如 “No, I didn't.” 或 “No, I didn't have a bike.” 这样能清楚表达否定，并与提问的时态一致。建议在回答类似过去经历的问题时使用完整句子，包含主语和动词。

× I don't know.

✓ I don't know.

在原问“Do you think bikes are popular in your country?” 中，学生回答“I don't know.” 是语法正确且时态一致的。此处为陈述现在时，表达不确定性，符合语境，无需改动。
