Bike— Part 1 Báo cáo

Gợi ý: 语法和时态错误较明显。应使用过去时（I didn’t have），并给出简短扩展说明以显得自然和有效。例如说明原因或回忆一件相关的事。回答尽量不超过五句，首句直接回答，然后用一两句具体细节支持，用连接词如“because”或“so”增加连贯性。

Ví dụ: No, I didn’t have a bike when I was a child. My parents couldn’t afford one, so I often walked to school instead. I remember watching other kids ride around the neighbourhood and wishing I could join them.

Gợi ý: 回答较直接但结构松散。第一句可以明确表达看法，然后用具体理由或例子支持（例如城市骑行、公共自行车系统、环境和健康原因）。注意保持时态一致，避免把个人经历混入广泛陈述中时产生模糊。使用连接词如“because”或“for example”使逻辑清晰。

Ví dụ: Yes, I think bikes are quite popular in my country because many people use them for short trips and commuting. For example, several cities have public bike-sharing systems and dedicated bike lanes, which makes cycling convenient and safe.

× No, I don't have a bike when I was a child.

✓ No, I didn't have a bike when I was a child.

语法问题类型 ID: 6（现在时问题）。 原句使用了现在时“don't have”来描述过去的情况，时态不一致。与时间状语“when I was a child”搭配时应使用过去时。建议将动词改为过去式“didn't have”。 注意：在否定过去时中使用助动词 did + not + 动词原形。

× Yes, I think so, but my parents didn't buy it for me.

✓ Yes, I think so, but my parents didn't buy one for me.

语法问题类型 ID: 5（过去时问题）。 原句中代词“it”指代不明确；在谈论一般物品（a bike）时，使用不定冠词加可数名词或用泛指代词“one”更自然。虽然过去时“didn't buy”本身正确，但应将“it”改为“one”或重复名词。建议改为“didn't buy one for me”或“didn't buy a bike for me”。
