Bike— Part 1 Báo cáo

Gợi ý: 首先，句子要直接回应问题并保持简洁。注意时态和动词形式（比如“didn't have”，“learn to ride”），并避免重复填充词（如“umm”，“I, I, I”）。可以用一到两句清楚交代过去的情况，并给出简短原因或结果。举例：用一般过去时描述童年并用连词连接理由。

Ví dụ: No, I didn't have a bike when I was a child. I tried to learn to ride several times but never succeeded, so my family didn't buy one for me.

Gợi ý: 先给出直接的观点句（肯定或否定），然后用一两句具体细节支持观点。注意词汇和搭配（如“popular in my country”，“in recent years”，“shared bikes”而不是“money free bikes”）。避免不必要的停顿和语法错误，可以提到时间、原因和影响作为支持细节。

Ví dụ: Yes, I think bikes are very popular in my country. In recent years, shared bike schemes have expanded rapidly, and since about five years ago many cities launched dockless bikes that people can unlock with an app, which made cycling much more common.

× Unfortunately, I don't have a bag because when I was little, I was trying to learning how to riding, ride a bike, but I, I, I hadn't learned it, umm, eventually. So I, in that way, umm, I didn't have a bike.

✓ Unfortunately, I didn't have a bike because when I was little, I was trying to learn how to ride a bike, but I hadn't learned it eventually. So, in that way, I didn't have a bike.

存在动词后接 -ing 或不定式形式错误（Grammar Problem Type ID 8）。在英语中，某些短语后面应接不定式（to + 动词原形）或动名词（动词+ing），取决于动词搭配。原句中的 'trying to learning' 应改为 'trying to learn'（trying 后接 to + 动词原形），'how to riding, ride a bike' 应合并为 'how to ride a bike'（how to 后接动词原形）。另外，把时态与句意保持一致，将开头的现在时 'don't have' 改为过去时 'didn't have' 与上下文的过去时间 'when I was little' 对应。建议：记住常见搭配，例如 'try to do'（尝试去做）、'learn to do' 或 'learn how to do'（学会如何做），不要把 to 与动名词连用。

× I would say umm, definitely, especially uh, there was a specific period since five years ago, uh, like China, umm, produce, umm, money free bikes, uh, to put on in the elevator uh, of city.

✓ I would say definitely. Especially about five years ago, China produced many free bikes to put around the cities.

这是过去时使用错误（Grammar Problem Type ID 5）和用词顺序问题。原句中 'there was a specific period since five years ago' 与时态混乱，'since five years ago' 应用过去时短语如 'about five years ago' 或现在完成时配合 'since'。动词 'produce' 应使用过去式 'produced' 来表达过去发生的事情；'money free bikes' 用词不当，应改为 'many free bikes' 或 'free bikes'；'to put on in the elevator of city' 表达混乱，意图是指放在城市各处，改为 'to put around the cities' 更自然。建议：描述过去发生的具体时间点时用过去式（例如 'five years ago' + past），注意短语搭配和词序，保持句子简洁清晰。
