Bike— Part 1 Informe

Sugerencia: 内容清晰，回答直接且有具体细节（年级、父母决定、练习时长）。要改进的地方：1) 句子稍长且重复（如兩次使用“I think”），可合并精简以更自然流畅；2) 可加入一个简短的总结性评价或感受以增强完整性；3) 注意时态和小地方的用词（例如用“spent about a month practising”更地道）。建议把回答控制在3-4句内，避免赘述。

Ejemplo: Yes. I had a small bike when I was in Year 4. My parents bought it so I could ride to and from school, and I spent about a month practising before I felt confident. It was a lot of fun and gave me more independence.

Sugerencia: 回答有一个清晰的观点（过去普及，现在情况不同），但句子未完成，显得中断。需要：1) 补全句子并给出当前情况的具体原因或例子（如汽车增多、地铁发展、城市扩张、骑行设施）；2) 使用连接词使逻辑更连贯（e.g. "however", "because", "for example"）；3) 保持简洁，不要用口头语（如“well”）太多。目标是3-4句，包含对比和原因。

Ejemplo: That's a mixed picture. Twenty years ago bikes were very common because there were fewer cars and cities were smaller, so cycling was convenient. However, nowadays many people prefer cars or the subway because cities have grown and traffic is heavier. For example, in big cities bike lanes are limited, so cycling is less popular than before.

× I think when I was in year 4 in primary school, my parents decided that I should start to ride a bike to and from school and they bought me a very small bike and I think I had spent around one month practicing it.

✓ I think when I was in year 4 in primary school, my parents decided that I should start to ride a bike to and from school. They bought me a very small bike, and I think I spent around one month practising it.

问题类型：过去时态使用不当。原句中同时使用了简单过去时（decided, bought）和过去完成时（had spent），但语境只是描述过去发生的事件，时间顺序清晰，无需用过去完成时。建议将“had spent”改为简单过去时“spent”。此外，句子过长，建议拆分为两句以提高可读性，并将“practicing”改为英式拼写“practising”或保持“practicing”视区域而定。修正后时态一致且符合叙述过去事件的习惯用法。

× And back then the cities were kind of small. So it was really easy for you to ride from one point to another.

✓ And back then the cities were kind of small, so it was really easy to ride from one point to another.

问题类型：介词或代词使用不准确。原句中的“it was really easy for you to ride”在口述一般经历时用“for you”显得不必要且把叙述指向听话者，改变了原意。更自然的表达是省略“for you”，直接用不定式结构“It was easy to ride...” 表示普遍情况。此外把两句合并为一个复合句更流畅。
