自行车— Part 1 評分報告

建議: 回答时时态使用不当，句子结构不自然且太简短。应直接用过去时表述主题句，并补充一两句具体细节以显得自然流利。例如说明为什么没有、是否羡慕同伴或用其他交通工具。使用连接词使表达更连贯。

範例: No, I didn't have a bike when I was a child. My family couldn't afford one, so I usually walked to school or took the bus. I sometimes borrowed my neighbor's bike on weekends, which I really enjoyed.

建議: 回答重复且不够具体。应直接给出观点并用过去与现在对比或原因进行拓展，使用连接词（for example, because, so）使回答更有逻辑。提供具体例子或数据会更好。

範例: Yes, bikes were very popular when I was young, and they are still common today. For example, many students used bicycles to commute to school, and in recent years bike-sharing schemes have made cycling even more widespread in cities.

× No, I don't have a bike in my childhood.

✓ No, I didn't have a bike in my childhood.

问题类型（过去时错误）：原句使用了一般现在时助动词“do/does”来描述过去的情况，时态不匹配。因为问句是“Did you have... when you were a child?”，答句应使用一般过去时。建议在过去时陈述过去事实时使用助动词 did + 动词原形，或直接使用过去式动词。例如："I didn't have" 或 "I did not have"。

× Yes, when I was young. Bikes are popular in my country.

✓ Yes, when I was young, bikes were popular in my country.

问题类型（现在时错误）：原句把陈述过去时期（"when I was young"）和现在时“are popular”混合，导致时态不一致。若要说过去年轻时自行车流行，应把主句也改为过去时，即使用 'were'。如果想表达现在仍然流行，则应去掉时间状语“when I was young”。建议根据时间状语统一时态：谈过去用过去时（were/popular），谈现在用现在时（are/popular）。
