Bike— Part 1 채점 보고서

제안: 语法错误和时态使用不正确，表达不自然且冗余。回答应直接使用过去时并包含主题句与简短补充。建议把句子改为：先用一句简单的主题句（I had a bike when I was a child.），然后可加一两句具体细节，如为什么喜欢或谁送的，注意不要超过5句。

예시: I had a bike when I was a child. It was a small red bicycle that my parents bought me for my sixth birthday, and I used to ride it to the park every afternoon.

제안: 表达总体思路清楚但有重复、衔接词使用不当（重复使用 'but'），以及细节不够具体。建议用一到两句主题句说明观点，再用1–2句用连词补充具体原因或例子，避免口头语和冗长。示例中要包含具体场景或数据会更好。

예시: Bikes are fairly popular in my country, though they are used mainly for leisure rather than commuting. For example, many families and young people cycle in parks and along river paths at weekends, especially during spring and autumn.

× Yes, I have a bike when I was a child.

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

这是时态错误（Present tense issue）。原句使用现在时态“have”但时间状语“when I was a child”表明动作发生在过去，应该使用过去时“had”。建议：遇到表示过去时间的时间状语（如 when I was a child / last year / in 2005 等），动词用过去时。

× Bikes are quite popular in my country, but it is not for daily transportation.

✓ Bikes are quite popular in my country, but they are not used for daily transportation.

这是时态与代词使用结合的问题，主要为现在时态使用不当和代词不匹配（属于 Present tense issue 与代词相关）。原句中“it is not for daily transportation”用单数代词“it”指代复数“bikes”不恰当，且句子缺少被动结构或动词，正确表达应为“they are not used for...”。建议：复数名词用复数代词（they），表达“不是用于日常交通”时常用被动语态“are not used for...”。

× But uh, people like to ride bike in the weekend for leisure.

✓ But, uh, people like to ride bikes on the weekend for leisure.

这是动词+ -ing 形式/名词复数和介词使用的问题（归类为 Verb + -ing form，兼顾介词与数）。原句中“ride bike”在习惯用法中应为“ride bikes”或“ride a bike”；此外英文中通常用介词“on the weekend”（美式也可说“on weekends”或“at the weekend”），所以改为“ride bikes on the weekend”。建议：动词 + 名词时注意名词单复数；使用合适介词：on the weekend / on weekends / at the weekend。
