Bike— Part 1 Informe

Sugerencia: 回答基本没有直接、清晰地表达完整意思。过去的经历应使用一般过去时，因此应将 “haven't” 改为 “didn't have”。“I don't make it” 表达不自然，听者无法理解你的具体原因。建议先直接回答，再补充一个明确原因，最好控制在1—2句话内。

Ejemplo: No, I didn’t have a bike when I was a child because my parents couldn’t afford one. I usually walked to school instead.

Sugerencia: 回答直接，但内容过于简短，而且主语是复数 “bikes”，所以应使用 “they are”，而不是 “it is”。建议补充一个具体原因或例子，例如共享单车很普遍、很多人骑自行车通勤，这样可以使答案更完整、更有说服力。

Ejemplo: Yes, bikes are very popular in China, especially in large cities. Many people use shared bikes to commute because they are cheap and convenient.

× No, I haven't back because, uh. I don't make it.

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

问题中的问句使用了过去时“Did you have...”，回答也应使用过去时。原句中的“I haven't”是现在完成时，不适合回答童年时期的经历。建议回答过去经历时使用“didn't + 动词原形”，例如：“I didn't have one.”

× Yes, it is very popular in China.

✓ Yes, bikes are very popular in China.

这里谈论的是“bikes”这一类事物，应该使用复数名词“bikes”，并搭配复数动词“are”，而不能使用单数代词“it”和单数动词“is”。谈论一类事物时，可以使用复数形式，例如：“Bikes are popular.”

× Yes, it is very popular in China.

✓ Yes, bikes are very popular in China.

“it”是单数代词，不能指代复数名词“bikes”。指代复数事物时应使用“they”，不过在这个句子中直接重复主题“bikes”更加自然。
