Bike— Part 1 채점 보고서

제안: 回答直接但过于简短且重复（使用了 did/have 结构不自然）。建议用更自然的表达并补充一到两个细节，如你几岁开始骑，骑车的频率或记忆中的一次经历。注意句子数量不超过五句，并使用连词衔接细节。

예시: Yes, I did. I got my first bike when I was about seven and rode it to school almost every day. It was a small red bike with training wheels at first, and learning to ride without them is one of my fondest childhood memories.

제안: 回答信息较充分但表达不够流畅，存在时态与连词使用问题（例如同时使用 'was' 与 'is'，以及冗余的连接词）。建议明确现在与过去的对比，使用清晰的连接词（however, although, nowadays 等），并提供具体原因或例子，如私家车和公共交通的普及或政策变化。控制在最多五句内。

예시: Bicycles used to be very common in my country, especially in the last century, because they were affordable and convenient. However, nowadays many people prefer cars or public transport due to faster lifestyles and better road infrastructure, so cycling is less popular as a main mode of transport.

× Yeah, I think it was popular in last century, but as the society was developing rapidly, so it is not a really popular transportation option that people will choose now, but it was popular.

✓ Yeah, I think bicycles were popular in the last century, but as society has developed rapidly, they are not a very popular transportation option people choose now, although they used to be.

问题类型：现在时/时态使用不当（Present tense issue）。解释：原句中时态混用且有冗余连词“so”，使句子不通顺。‘was popular in last century’ 应使用复数名词“bicycles”并加定冠词“the last century”；描述过去习惯用过去时或过去进行时，如“used to be”或“were”。提到从过去到现在的变化需用现在完成时或现在时，如“has developed”与“are not ... now”。此外，“so”在“but ... so”结构中多余并产生逻辑冲突，应删去或改为“although/however”。建议改正为："I think bicycles were popular in the last century, but as society has developed rapidly, they are not a very popular transportation option people choose now, although they used to be." 这样时态一致，逻辑清晰，语言自然。
