Bike— Part 1 Relatório

Sugestão: 回答内容直接但表达有语法和连贯问题。要点：1) 时态和语法要准确（例如“because I didn't know how to ride a bike until I was 12”）；2) 结构可更清晰，先给主题句再补充细节；3) 用连接词改善衔接（e.g. “however”, “because”）；4) 注意信息完整性，例如解释为什么城市不适合骑车。请把句子控制在最多5句内，避免重复。

Exemplo: No, I didn't have a bike when I was a child. I didn't learn to ride until I was about twelve, so my parents never bought one for me. Besides, my city wasn't very suitable for cycling because roads were narrow and traffic was heavy. Therefore, I mostly walked or took public transport to school.

Sugestão: 回答观点明确但语法和用词需要改进。要点：1) 注意动词形式和主谓一致（e.g. “people ride bicycles”）；2) 使用连接词使句子更流畅（e.g. “In many cities,” “and”）；3) 提供更具体的例子或原因（如共享单车的影响、通勤距离、环保原因）；4) 控制句子数量与长度，避免重复信息。

Exemplo: Yes, bikes are quite popular in China, especially in urban areas. In many cities people often ride bicycles to work or school because journeys are short and traffic is congested. The rise of shared-bike services has also made cycling more convenient and affordable, encouraging more people to choose bikes for short trips.

× No, I didn't have a bike when I was a child because I don't know how to ride a bike until I was like 12.

✓ No, I didn't have a bike when I was a child because I didn't know how to ride a bike until I was about 12.

问题类型: 现在时态使用错误（ID 6）。句子中描述的是过去发生并持续到另一过去时间的事实，应该使用过去时而不是现在时。将 don't know 改为 didn't know，并将 like 改为更正式的 about/approximately。建议：当谈论过去的状态或能力时，用过去时（didn't know, couldn't 等）。

× But it is usual in my city which is not suited for riding a bicycle.

✓ But it was common in my city, which was not suited for riding a bicycle.

问题类型: 句子结构错误（ID 26）。原句时态混用且定语从句位置与时态不一致。主句谈过去情况应使用过去时（was common），定语从句也应与之保持时态一致（which was not suited）。建议：保持时态一致，改为“was common”和“which was not suited for...”。

× In most cities people riding bicycle to work and to school and we also have the shared bicycle service and made cycling more common and convenient.

✓ In most cities people ride bicycles to work and to school, and we also have shared bicycle services that make cycling more common and convenient.

问题类型: 动词 + -ing 形式误用（ID 8）及其他语法问题（复数、时态、从句结构）。原句中 people riding 应为一般现在时 ride（陈述常态），bicycle 应用复数 bicycles，且并列句中时态与结构需要一致：we have... that make... 而不是 made。建议：描述常态用一般现在时（people ride），名词复数（bicycles），并使用关系从句或并列结构保持主谓一致。
