Bike— Part 1 채점 보고서

제안: 用词与句子结构需要更准确、简洁，并注意拼写错误（如 back 应为 bike）。回答应有明确主题句，随后用一两个具体细节支持，避免冗长。可适当使用连接词使表达更连贯，同时控制在最多5句内。

예시: Yes, I had a bike when I was a child. My mother bought it for me when I was about eight, and I learned to ride it within a few weeks. I used to cycle to school with my friends almost every day, which was great fun and made me feel more independent.

제안: 句子存在语法和用词问题（如 'committed to buy bike'、'rush harvests'），表达不够清晰。应该先给出直接观点，再用一两个具体原因或例子支持，使用合适的连接词并纠正搭配和复数形式。保持简洁明了并避免冗余。

예시: Yes, bikes were very popular in my country, especially when I was younger. At that time there was no subway, so many students and workers relied on bicycles for daily commuting. However, their number has declined since the metro network expanded.

× Yes, I had a back when I was a child.

✓ Yes, I had a bike when I was a child.

原句将“bike（自行车）”误写为“back”。这是拼写错误导致的名词错误，属于单复数/名词形式类问题。应使用“bike”表示自行车。建议写作时注意拼写并复读检查，或朗读句子确认单词是否正确。

× So I often cycle to school with my friends which was really fun and made me feel more independent.

✓ So I often cycled to school with my friends, which was really fun and made me feel more independent.

句子时间背景为过去（when I was a child），主要动作应使用过去时。原句中使用了现在时“cycle”与过去描述不一致，造成时态和句子结构混乱。将“cycle”改为过去式“cycled”，并在“friends”后加逗号引导非限制性定语从句更清晰。建议统一段落时态，描述过去经历时全部使用过去时。

× Yes, bikes used to be very popular mode of transport in my country, especially when I was a child, because there wasn't a subway system then and many students and workers committed to buy bike.

✓ Yes, bikes used to be a very popular mode of transport in my country, especially when I was a child, because there wasn't a subway system then and many students and workers chose to buy bikes.

原句有几个问题：1) “very popular mode”前缺少不定冠词“a”，正确为“a very popular mode”；2) “committed to buy bike”用法不当，动词搭配和冠词/复数错误。应使用“chose to buy bikes”或“were buying bikes”。此外“bike”需用复数“bikes”与“many students and workers”一致。建议注意冠词使用与动词短语搭配，以及主语和名词复数一致。

× Many people rode bikes bicycles during the morning and evening rush harvests, although their numbers have declined since the metro network was built.

✓ Many people rode bicycles during the morning and evening rush hours, although their numbers have declined since the metro network was built.

原句有词语选择错误：“bikes bicycles”重复，应选择一个单词（通常用“bicycles”或“bikes”）；“rush harvests”是错误搭配，应为“rush hours”。因此将句子改为“rode bicycles during the morning and evening rush hours”。建议学习常用固定搭配（如“rush hour”）并避免重复近义词。
