Bike— Part 1 채점 보고서

제안: 回答要更连贯并且完成意思。首先用一句话直接回应并简要说明情况，然后用一到两句具体补充细节，避免断句和重复。注意时态一致，避免残缺句（如“but. But at first I couldn't.”应补全为能说明“开始不会骑”或“开始不能用”的完整句子）。建议使用连接词（e.g. but, however, because）使句子更自然。

예시: Yes, I did. My father gave me a bike for my birthday when I was a child, and I liked it a lot. However, at first I couldn't ride it well, so he practiced with me every weekend until I learned.

제안: 答案需更自然、连贯并提供具体原因或例子。避免填充词（如 "uh"）和断句。开头直接回答，再用两句说明原因或举例，使用连接词（because, therefore, so）并确保描述清晰（“cloudy” 用错，应该说“congested”或“traffic jam”）。

예시: Yes, I think bikes are quite popular. They are convenient and flexible for short trips, especially for students who can ride to school quickly. Because there is often heavy traffic in the mornings, riding a bike can save time and avoid long delays.

× Yes I did. When I was a child my father gave me a bike as a gift for my birthday.

✓ Yes, I did. When I was a child, my father gave me a bike as a birthday gift.

句子基本时态正确（过去时），但存在标点和词序的小问题：“Yes I did”后需逗号隔开，时间状语从句后加逗号使句子更清晰；“a gift for my birthday”更常用且更简洁的表达是“a birthday gift”。建议在口语中注意短停顿与常用搭配。

× I like it, but. But at first I couldn't.

✓ I liked it, but at first I couldn't use it well.

原句断句不完整且时态不一致。问的是过去拥有自行车的经历，前半句应使用过去式“I liked it”。“But.”是残句，应和后句合并并补全谓语，说明“不能做某事”，此处应是“couldn't use it well”或“couldn't ride it”。建议表达完整意思并保持时态一致。

× Yes, I think uh, go to school by bike is very convenient and very flexible.

✓ Yes, I think going to school by bike is very convenient and flexible.

在“think”之后作主语的动词要用动名词形式（-ing），因此应使用“going”。另外“very convenient and very flexible”中可去掉一个“very”使表达更自然。建议学习动词后作名词性的结构需用动名词。

× Because in the morning, many cars in traffic, it's very cloudy.

✓ Because there are many cars in traffic in the morning, the roads are very congested.

原句存在结构与词汇选择问题：以Because开头的从句需完整表达原因，原句“many cars in traffic”缺少谓语，且“it's very cloudy”与上下文不搭（cloudy指多云天气，与交通拥堵无关）。更恰当的表达是说明道路拥堵（congested）或交通繁忙。建议确保从句完整并使用与语境相符的词。
