自行车— Part 1 評分報告

建議: 回答要更自然且语法准确。注意时态和冠词，句子可稍微扩展以提供细节但不宜过长（最多5句）。例如可先直接回答，然后补充原因或简单描述经历，用连接词使表达连贯。

範例: No, I didn’t have a bike when I was a child. Instead, I usually walked to school or took public transport because my family couldn’t afford one. As a result, I didn’t learn to ride until I was a teenager.

建議: 注意主谓一致并减少填充词（如"uh"）。可以提供更具体的细节，比如哪里常见、原因的多方面解释及影响，使用连接词使逻辑清晰。仍然保持不超过5句。

範例: Yes, bikes are very popular, especially among students and office workers. They are economical and help people avoid traffic during rush hour. In many cities, there are dedicated bike lanes and affordable shared bicycles, which makes cycling convenient for short commutes.

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

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

错误类型：单数/复数或限定词遗漏。说明：原句中缺少限定词“a”用于修饰名词“child”。在英语中，当提到单个可数名词且没有其他限定词时，需要使用不定冠词“a/an”。改正建议：在“child”前加上“a”，即“a child”。

× Yes, it's very popular with students and company workers because it's, uh, very cheap.

✓ Yes, they're very popular with students and company workers because they're very cheap.

错误类型：第三人称单数/主谓一致问题。说明：句子主语是复数“bikes”，因此谓语应该用复数形式“they are (they're)”，而不是“it is (it's)”。原句用“it”把复数名词视为单数，导致主谓不一致。改正建议：把代词和动词改为复数形式，使用“they're”来对应“bikes”。
