Bike— Part 1 채점 보고서

제안: 回答太短且缺乏细节。你应直接回答后给出一到两句具体描述，例如什么时候有的、谁给的、常骑到哪里或你对自行车的感受。注意控制在最多5句并使用连接词使表达更自然。

예시: Yes, I did. I got my first bike when I was seven, a small blue one my parents bought for me. I rode it to visit friends and explore the neighborhood almost every day, which helped me feel more independent.

제안: 回答通顺但空泛，缺乏具体理由或例子。应先给出直接观点，然后用一到两句具体原因或例子支持（例如普及率、用途、城市设施或最近的趋势），并用链接词如“because”或“for example”连接。

예시: Yes, I do. Bikes are very popular, especially in cities, because many people use them for short commutes and there are plenty of bike lanes. For example, I often see commuters and students cycling to work or school during rush hour.

× Yes, I did.

✓ Yes, I did.

该句为对过去时问题（Did you have...）的简短肯定回答，使用助动词 did + 主语不需要动词原形，直接用 did 表示过去时，语法正确，无需更改。

× Yes, I do think bikes are popular in my country.

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

该句为对一般现在时问题（Do you think...）的肯定回答，使用强调助动词 do + 动词原形 think 表示肯定并带有强调，bikes are popular 使用一般现在时表示普遍事实，语法正确，无需更改。
