Bike— Part 1 채점 보고서

제안: 回答需要更自然、语法正确并且信息更具体。首先，句子应使用完整的语法，例如用“I didn’t have a bike”而不是“Unfortunately no”。说明原因时句子要通顺，可补充细节（例如家庭情况或其它交通方式）。回答长度控制在1–3句内，避免多余词汇。

예시: I didn’t have a bike when I was a child because my parents couldn’t afford one. Instead, I usually walked to school or took the bus with my friends.

제안: 回答需要更清晰、语法正确并提供具体细节与连接词。当前句子有语法与用词错误（例如“take back”不合适）。建议给出总体观点后用一两句具体例子或原因支持观点，如城市骑行、共享单车或周末郊游等，并使用连接词如“because”或“for example”。

예시: Yes, bikes are very popular in my country because many people use them for short trips and exercise. For example, on weekends families often go cycling in parks, and shared-bike services are common in cities.

× Unfortunately no, it's too expensive to buy bike for my parents.

✓ Unfortunately no, it was too expensive for my parents to buy a bike.

错误类型：冠词及句子结构错误。原句缺少不定冠词“a”，应为“a bike”。另外时态应与问题（过去时）一致，把“it's”改为“it was”。此外不定式短语位置调整为“for my parents to buy a bike”更自然。建议：记得可数单数名词前加不定冠词（a/an），回答关于过去的事情时使用过去时。

× Of course, nowadays people always take back on weekends or free time.

✓ Of course, nowadays people always go back (to cycling) on weekends or in their free time.

错误类型：动词及介词使用不当。原句“take back”用法不正确，应使用“go back”或更合适的动词“ride bikes / go cycling”。另外“free time”前应加介词“in”，以及表示空闲时间常用短语“in their free time”。建议：根据语境选用恰当动词（ride/go cycling），复核固定介词短语（in free time → in their free time）。
