Bike— Part 1 Report

Suggestion: 回答直接且可理解，但有语法错误、用词不准和表达不够丰富。建议： 1) 修正语法时态和所有格，例如使用“could”或“used to”描述过去的习惯，使用“my parents' bike”表示所有关系； 2) 添加一两句具体细节丰富内容（如为什么没有、偶尔骑行的场合或感受）； 3) 使用连接词使句子更流畅（例如“however”、“so”）。 示例练习目标：在三到五句内自然表达完整想法，注意时态和所有格。

Example: I didn’t have my own bike when I was a child; I used to borrow my parents' bike instead. However, I only rode it occasionally for short trips to the park because my parents preferred to drive us. I remember feeling excited whenever I could ride it with my older cousin.

Suggestion: 回答有观点，但表达含糊、句子未完成且有语法和搭配问题。建议： 1) 明确表达主要观点并用一到两个支持细节； 2) 修正搭配和句子结构，例如说“cities are well-designed for cycling”或“many cities have good cycling infrastructure”； 3) 避免口头语（如“you know”）并完成句子，使用连接词（e.g. “for example”, “so”）使逻辑清晰。

Example: Yes, I think bikes are very popular in China. Many cities have good cycling infrastructure and shared-bike schemes. For example, people can scan a QR code to unlock a bike and ride it for short trips, which makes cycling a convenient and affordable option.

× When I was a child I didn't have my own bike. I can only use my parents bike.

✓ When I was a child I didn't have my own bike. I could only use my parents' bike.

问题类型：过去时态错误（5）。原句中第一句使用了过去时（didn't have），但第二句用了现在时态的情态动词 can，时态不一致，应使用表示过去能力或许可的过去式 could。此外，“parents bike”缺少所有格标记，应为 parents' bike（父母的自行车）。建议：将 can 改为 could，使整个陈述保持过去时；同时在 parents 后加撇号以表示所有格。

× Absolutely. In China many cities are well placed. Some, you know, shared bikes on the streets so that people can scan the code and use the bikes everywhere and they can also.

✓ Absolutely. In China many cities are well planned. There are also shared bikes on the streets so that people can scan a code and use the bikes everywhere.

问题类型：介词/短语使用错误（11）及句子结构问题（26）。原句“well placed”用法不当，应为 well planned 或 well designed（计划/设计良好）。“Some, you know, shared bikes on the streets”句子结构不完整且语义不清，应改为 There are also shared bikes on the streets 来引出存在的事实。原句末尾“and they can also.”不完整，应删除或补全。建议：使用固定搭配 well planned，使用 there are 结构引出共享单车，并将 scan the code 改为 scan a code 更自然。
