Bike— Part 1 채점 보고서

제안: 回答要更连贯并遵守句子数量限制（不超过5句）。开头直接回答问题后，应用一到两句补充细节并使用连接词使句子连贯。注意语法：不需要重复“did have”，应说“I had a bike.” 另外不要在句中间断开，如“I went to school by bike.” 更自然。

예시: Yes, I had a bike when I was a child. I usually rode it to school every day because it was faster than walking. Also, I remember riding with my friends on weekends, which was lots of fun.

제안: 回答应更具体并用连接词扩展细节，避免句子残缺。开头直接给出观点，然后用原因、例子或比较来支持。可以说明不同人群如何使用自行车、何时更常用或与其他交通方式比较。保持句子自然，最多5句。

예시: Yes, bicycles are very popular in my country. Many students and workers use them for short trips because they are cheap and convenient. For example, in the morning you can see lots of people cycling to school or the market, especially in smaller towns.

× Yes, of course, I did have a bike when I was a child. At that time I. Go to school by my bike.

✓ Yes, of course, I had a bike when I was a child. At that time I went to school by my bike.

问题类型：句子结构与时态混合错误（对应ID 26 和 5/6）。 解释：原句中“I did have a bike”在一般过去时语境中冗余，多数情况下直接使用过去时“I had a bike”更自然。之后的句子“At that time I. Go to school by my bike.” 有句子断裂，且动词时态不一致（“Go”为一般现在时）。应使用过去时“went”与前文保持时态一致。建议：在叙述过去经历时，统一使用一般过去时；避免句子中途断开，保持主谓完整。

× Yes, I do. I think that bicycles are very popular in my country. People use the bicycle to go to school. And.

✓ Yes, I do. I think that bicycles are very popular in my country. People use bicycles to go to school.

问题类型：句子结构错误（对应ID 26）与单复数使用不一致（对应ID 1）。 解释：第一句“Yes, I do.” 回答当前时态问题可以保留，但后文“People use the bicycle to go to school.”中“the bicycle”不符合泛指含义，应该用复数“bicycles”或不定冠词来表示一般情况。另外句末的“And.” 是不完整的片段，应删除或补全。建议：当谈论普遍现象时使用复数名词（bicycles）或不定冠词；避免留下不完整的连词。
