Bike— Part 1 채점 보고서

제안: 回答需要時態正確並且更完整。先直接回答問題（使用正確的過去式），然後給出一到兩句具體細節來擴展。例如可以說明擁有自行車的時間、誰送的或常去哪裡騎。注意用連接詞讓句子流暢。

예시: Yes, I did. I had a red bicycle when I was about eight, which my parents bought me for my birthday. I used to ride it to school and around the neighborhood every afternoon.

제안: 回答應更具體並給出理由或例子來支持觀點。先明確表態，然後用連接詞（because, although, however）説明為何不流行，例如交通狀況、天氣或基礎設施問題，最後可給出一個比較或個人觀察。

예시: No, I don't think they are very popular. Mainly because many cities are crowded and lack safe bike lanes, so most people prefer cars or public transport. For example, I rarely see adults commuting by bike in my city, except on weekends.

× Yes, I have.

✓ Yes, I did.

问题类型：现在时使用不当（应使用过去时）。解释：考官问的是过去（"Did you have...when you were a child?"），所以回答也应使用过去时。原句"Yes, I have."使用的是现在完成时/现在时态，与提问时态不一致。建议：遇到以"Did"开头的过去时问句，回答用过去时，例如"Yes, I did."或更具体的"Yes, I had a bike."。

× No, I don't.

✓ No, they aren't.

问题类型：现在时使用不当（主谓不一致与代词/助动词选择错误）。解释：考官问的是一般现在时的陈述（"Do you think bikes are popular in your country?"），期待回答关于"bikes"是否"are popular"的判断。原句"No, I don't."用的是第一人称单数助动词（表示不做某事），与问题不匹配。更自然的否定回答应直接针对主语和形容词，使用复数be动词："No, they aren't."；若想更完整可说"No, I don't think they're popular."。建议：回答关于事物是否某种状态时，直接针对事物用be动词或用完整句"I don't think..."。
