Bike— Part 1 채점 보고서

제안: 语法和时态错误需要改正；回答太简短且缺乏细节。建议使用正确的过去时，先给出直截了当的主题句，然后补充一两句具体细节（比如为什么没有、是否想要、有没有其他代替交通工具）。控制在最多五句内，并使用连接词如“because”或“so”。

예시: No, I didn’t have a bike when I was a child because my family lived in a very hilly area and it wasn’t practical. Instead, I usually walked or took the bus to school, which made me less interested in cycling.

제안: 回答内容基本相关但不够具体，口语稍显非正式且时态用词不够准确。建议用更完整的句子说明为什么流行，举例说明使用场景或变化趋势，使用连接词如“because”、“for example”来增强连贯性。保持在三到五句内，避免缩略词或太口语化的单词。

예시: Yes, bicycles are still very popular in my country because they are cheap and convenient for short trips. For example, many people use bikes to commute to work or to go to the market, although some younger people now prefer electric scooters.

× I don't have a bike when I was a child.

✓ I didn't have a bike when I was a child.

问题类型：现在时使用不当。 原句中使用了现在时态“don't have”但时间状语是“when I was a child”（过去时），时态不一致。正确做法是把动词改为过去时“didn't have”。建议：当句子包含过去时间词（如 when I was a child, last year, in 2010 等）时，使用过去时态；否定过去时用 did not + 动词原形。

× Yeah, very popular. People used to use it to commute.

✓ Yeah, it's very popular. People used to use them to commute. / Yeah, very popular. People used to use bikes to commute.

问题类型：过去时与代词/指代错误。原句在第一句省略主语和动词，口语可接受但更完整的回应应为“it's very popular”（现在一般事实）。另外，第二句中“it”指代复数名词“bikes”不一致，应使用复数代词“them”或直接重复名词“bikes”。如果强调过去的习惯用法“used to”，保持过去结构；若说明现在普遍情况应使用一般现在时（People use them to commute）。建议：保持时态和代词一致。若指代复数名词用“they/them”，或直接重复名词以避免歧义。
