Bike— Part 1 채점 보고서

제안: 你的回答过于简短且时态错误。应直接回答问题并用过去时，然后补充一两句具体细节（比如什么时候得到的、骑车的频率或与谁一起骑），使用连接词使句子连贯。避免超过五句话。

예시: Yes, I did. I got my first bike when I was seven and rode it almost every day after school. It was a small red bicycle that my parents bought for me, and I often rode it with my neighbors to the park.

제안: 回答有拼写错误和表达不够具体。应直接作出判断，使用正确单词（bike），并提供具体原因或例子（如城市骑行、共享单车普及、环境意识增强等），使用连接词如 because 或 for example 来组织句子。

예시: Yes, I think bikes are very popular in China because of the rise of bike-sharing services and increased environmental awareness. For example, people often use shared bikes for short trips in cities, which is convenient and cheap.

× Yes, I have.

✓ Yes, I did.

原句使用現在式"have"回應過去式問題（"Did you have..."），時態不一致。正確做法是用過去式回答：用"did"或完整句"Yes, I had a bike." 建議在回答過去經歷時把動詞改為過去式，或直接說完整句子以避免時態錯誤。

× Yes, I think back is popular in my country.

✓ Yes, I think bikes are popular in my country.

原句"I think back is popular..." 結構與詞彙使用錯誤：一是單詞拼寫錯誤（應為"bike"或複數"bikes"），二是數量與動詞一致性有問題。因為在陳述一般事實時通常使用複數名詞和現在式動詞，且主語為複數時動詞使用複數形式"are"。建議改為"I think bikes are popular..." 或更完整表達"I think bicycles are popular in my country."

× My country is China.

✓ My country is China.

句子本身文法正確，無需更改。這裡列出以確認沒有單複數錯誤。
