自行车— Part 1 評分報告

建議: 回答不太连贯且含语法错误。建议：1) 开头用一句明确的主题句直接回答（肯定或否定）；2) 用过去时表达已发生的事情；3) 用连接词衔接补充信息；4) 注意动词形式和冠词（ride a bike, learned）；5) 控制长度，不超过5句。示例结构：直接回答 + 说明原因/细节 + 简短结论。

範例: No, I didn't have a bike when I was a child. I couldn't ride a bike, so my parents never bought one for me. Later, when I was about ten, I learned how to ride with my cousins, but I still didn't own one.

建議: 内容有意思但表达混乱且时态不一致。建议：1) 用清晰的时间表达（e.g. in the 1990s）；2) 用连词组织原因（e.g. because, so）；3) 避免重复和语音填充词（uh）；4) 给出具体对比或现在情况的补充细节；5) 控制句子数量与长度。

範例: Yes, I think bikes used to be very popular in my country, especially in the 1990s because many families couldn't afford cars. As a result, people relied on bicycles for short trips and commuting. Nowadays more people own cars, so bike use has decreased in cities.

× When I was a child I never had a bike because I can't ride bike actually.

✓ When I was a child I never had a bike because I couldn't actually ride a bike.

句子时态混用：开头用了过去时（When I was a child / I never had），但后半句使用了现在时 can't，导致前后时态不一致。应将 can't 改为过去式 couldn't，且 ride 后需要不定冠词 a。建议：回顾一般过去时的用法，描述过去的能力或习惯时用 could/couldn't。

× When I study how to ride a bike.

✓ I studied how to ride a bike.

句子结构不完整且时态错误：独立使用 When 引导的从句但没有主句，且 study 使用现在时而整体叙述在过去，应把句子改为完整的过去时陈述句（I studied/how I learned），或者改为完整的从句+主句结构。建议：把时间背景统一为过去，避免使用不完整的从句。

× I think bikes are popular in our country, especially in 1998, because in 1990, as people didn't, people didn't have so many cars.

✓ I think bikes were popular in our country, especially in the 1990s, because in 1990 people didn't have so many cars.

时态和时间表达错误：说到过去的事实（1990 年代），主句应使用过去时 were，而不是现在时 are；also “especially in 1998” 与后面泛指 1990 年代不一致，且要用 the 1990s 表示十年。句中多余的片段 "as people didn't," 是不完整重复，应删除。建议：谈论过去时用一般过去时，并用正确的十年表达法（the 1990s）。

× Uh, they can only ride a bike to go.

✓ They could only ride a bike to get around.

结构和词语搭配不当：在谈论过去情况应使用过去时 could，而 notional verb "to go" 在此搭配不自然，常用短语是 "get around" 或 "travel"。因此改为 "could only ride a bike to get around" 更通顺。建议：学习常用搭配（get around/travel/commute）并保持时态一致。
