Bike— Part 1 Report

Suggestion: 回答较为直接，但存在语法错误、重复和停顿。建议：1) 用一两句清晰地陈述事实（主题句），如“I didn’t have my own bike as a child.” 2) 用一到两句具体补充细节并用连接词，使语句连贯，例如说明谁的自行车、什么时候骑、感受或原因。3) 修正语法（时态和代词）并避免填充词“uh”。例如使用过去时和正确的所有格。

Example: I didn’t have my own bike when I was a child. Instead, I often rode my grandmother’s or my mother’s bike when they weren’t using it, usually in the afternoons around our neighborhood. I enjoyed those rides because they felt like small adventures and saved me the cost of buying a new bicycle.

Suggestion: 回答大意明确，但表达混乱、语法不准确且信息不够具体。建议：1) 开头给出直接回答（例如“Yes, they were very popular”或“No, fewer people use them now”），然后用连接词（e.g. However, Nowadays）补充原因或变化。2) 提供具体时间、原因或比较（如城市化、共享单车的出现）以丰富内容。3) 注意主谓一致和时态。

Example: Bikes used to be extremely popular in China, especially about 20 to 30 years ago when most families owned at least one. However, nowadays fewer people rely on private bicycles because of the rise of cars and public transport, although shared bikes have made cycling convenient again in many cities.

× When I was a child, I didn't have my own bike. I used my, uh, grandma and my mother's back when I when they didn't use them.

✓ When I was a child, I didn't have my own bike. I used my grandma's and my mother's bikes when they weren't using them.

句子涉及过去的习惯或反复发生的动作，应使用过去时态并保持名词和所有格的一致。原句中“used my, uh, grandma and my mother's back when I when they didn't use them”结构混乱： 1) “used my grandma and my mother's back”错误地把人当作物品；应改为“used my grandma's and my mother's bikes”。使用所有格（'s）来表示所有权。 2) “when I when they didn't use them”有重复和词序问题，应改为“when they weren't using them”（过去进行或过去简单都可，这里用过去进行强调在他们不使用时我使用）。 建议：用所有格表示所属，保持过去时一致，避免重复词。

× Yeah, bikes. Bikes are very popular in China for a long time, maybe around 30 years ago, 30 years.

✓ Yes, bikes have been very popular in China for a long time, maybe for about 30 years.

原句存在数与时态搭配问题： 1) “Bikes are very popular in China for a long time”时态错误，应使用现在完成进行或现在完成时（have been）来表示从过去持续到现在的情况。 2) “maybe around 30 years ago, 30 years”用法重复且与前半句冲突。正确表达应为“for about 30 years”或“since about 30 years ago”。 建议：用“have been”＋时间段（for ...）来表达持续性的流行；避免重复信息。

× At that time almost every fam family have their own bikes and one adult have one bike.

✓ At that time almost every family had its own bike and each adult had one bike.

这是主谓一致和时态问题： 1) “every family”作为单数，动词应为单数过去式“had”，而不是“have”。 2) “their own bikes”与“every family”对应通常用单数所有格“its own bike”，或也可用复数但需保持一致。更自然地用“each adult had one bike”来表示每个成年人有一辆。 建议：注意“every/everybody”等词后接单数动词；在叙述过去事实时使用过去式。

× And nowadays people are preferred.

✓ And nowadays people prefer them.

代词和动词用法错误： 1) “are preferred”是被动语态，句子没有明确的施动者，且意思应为“人们更喜欢（自行车）”，因此应使用主动语态“people prefer them”。 2) 若要表达“现在人们更喜欢（其他交通工具）”，需明确比较对象，例如“people prefer cars or e-bikes now”。 建议：根据想表达的含义选择主动或被动；指代要明确（使用them或具体名词）。
