Bike— Part 1 채점 보고서

제안: 句子時態與語法錯誤較多，表達不夠自然。建議：1) 使用正確的過去式（例如 had, bought）。2) 先用主題句直接回答（Yes/No），然後用一到兩句具體細節補充。3) 句子不應過長或重複，控制在最多五句內。示例修改點：把“I have my first bike”改為“I had my first bike when I was seven.”把“buy”改為“bought”，把“when I was birthday that”改為“for my birthday.”

예시: Yes, I did. I had my first bike when I was seven. My grandfather bought it for my birthday, and I remember learning to ride it in the park near our house.

제안: 內容不夠連貫且語法與表達不完整。建議：1) 開始時直接回答（Yes/No/It depends），然後用連接詞（however, but, nowadays）清晰對比過去與現在。2) 提供具體原因或例子（例如交通、汽車普及或共享單車）。3) 保持句子結構正確並控制在最多五句內。

예시: It used to be more popular, but not so much now. Ten years ago, many people rode bikes for short trips, however today more people prefer cars or public transport because cities have become busier and parking is easier to find.

× Of course, when I was seven years old I have my first bike.

✓ Of course, when I was seven years old I had my first bike.

这是现在时和过去时混用的问题。句中有时间状语“when I was seven years old”，表示过去的时间，主句应使用过去时。将“have”改为过去式“had”。建议：遇到明确的过去时间标志（如 when I was... / last year / in 2000 等）时，主句动词也应使用过去时。

× My grandfather buy a bike for me when I was birthday that.

✓ My grandfather bought a bike for me for my birthday then.

原句有多个问题，但主要是动词时态错误和词序/搭配不当。动词“buy”应改为过去式“bought”，因为动作发生在过去；“when I was birthday that”是不正确的表达，正确表达应为“for my birthday then”或“on my birthday then”。建议：动词根据时间使用正确时态，表达生日的短语用“for my birthday”或“on my birthday”。

× Actually, the bike is popular. 10 years ago, but now the bike is not popular.

✓ Actually, bikes were popular 10 years ago, but now bikes are not popular.

句子中存在时态和数的一致性问题。第一句用现在时“is popular”与时间状语“10 years ago”冲突，应使用过去时“were popular”。另外，泛指自行车应使用复数“bikes”，保持一致。建议：描述过去的情况用过去时；谈论一般事物时注意单复数一致（泛指可用复数）。
