Bike— Part 1 Báo cáo

Gợi ý: 总体表达清楚，回答直接，但存在语法错误、重复赘述和语速停顿（填充词“uh”）问题。改进要点：1) 修正时态和动词形式错误（例如 use ‘tried’而非 ‘try’）；2) 删除多余重复（例如去掉第二次“I at first”）；3) 用连接词使句子更连贯（例如 however, finally）；4) 控制长度，不超过5句；5) 避免填充词，适当停顿或用连接词替代。

Ví dụ: Yes, I did. I taught myself to ride a bike when I was young. At first I couldn’t keep my balance and fell over several times; however, after practicing for a few days I finally managed to ride steadily.

Gợi ý: 回答直接但表达不够地道，存在用词和句子结构错误（例如 'landed by' 不合适），以及重复赘述（'borrowed by people by convenience'）。改进要点：1) 用更合适的词汇描述共享单车（e.g. 'dockless/shared bikes are widely available'）；2) 使用连接词解释原因（e.g. because, therefore）；3) 给出具体例子或影响以丰富内容；4) 避免重复和冗余短语。

Ví dụ: Yes, I think bikes are very popular in my country because dockless shared bikes are everywhere. They are cheap and convenient for short journeys, so many people use them to commute or run errands.

× I used to teach myself uh, how to ride a bike at first, uh, I at first I always failed to keep my balance, but after try for several times I can finally handle it.

✓ I used to teach myself how to ride a bike. At first I always failed to keep my balance, but after trying several times I was finally able to do it.

问题类型：过去时错误（Past tense issue）。 解释与建议（简体中文）：原句中时态混用且词形错误： 1) “after try for several times” 中 “try” 应为动名词或现在分词形式 “trying”，表示经历过的动作。应使用“after trying several times”。 2) 前半句使用了过去习惯 “used to”，后半句突然用现在时 “can finally handle it”，时态不一致。应该用过去时，如 “was finally able to do it” 或 “could finally do it”。 3) 句子断句不清，建议拆成两句使表达更自然。 改进建议：注意保持整个叙述的时态一致（描述过去经历时使用过去时或过去习惯结构），并使用正确的动词形式（如动名词）来表示“经过……之后”。 举例替换："after trying several times"，"was finally able to do it"。

× As you can see, there are so many shared bikes in the public, which can be landed by, which can be borrowed by people by convenience.

✓ As you can see, there are many shared bikes in public places, which can be conveniently borrowed by people.

问题类型：句子结构错误（Sentence structure errors）。 解释与建议（简体中文）：原句存在表达不自然和用词错误： 1) “in the public” 用法不当，应改为 “in public” 或更清晰的 “in public places”。 2) “which can be landed by” 不合适且意义模糊，可能是想表达“可以取用/停放”，但在这里应删除或改为更明确的动词。 3) “which can be borrowed by people by convenience” 中“by convenience” 用法错误，应改为副词“conveniently”并放在动词前或后以修饰整个短语："conveniently borrowed by people"。 改进建议：简化并明确句子结构，使用正确的介词短语和副词位置。可将句子重构为："there are many shared bikes in public places, which can be conveniently borrowed by people."
