Bike— Part 1 채점 보고서

제안: 语法与时态不一致，句子较长且重复，信息组织不够清晰。回答应先用一句主题句直接回应问题，然后用一到两句具体细节支持，注意过去时态（was/were, had, taught, was afraid），并使用连接词使句子更连贯。尽量不要超过五句。

예시: Yes, I had a bike when I was a child. It was very special to me because my father taught me how to ride it. At first I was afraid of falling, but with his encouragement I practised a lot and eventually I started to enjoy cycling.

제안: 句子中主谓不一致及词汇发音/拼写问题（student -> students; rent -> rent/you rent; envir -> environmental/convenient）。回答结构可以更清晰：先给出总体观点，然后用具体例子和原因支持，使用连接词（for example, because, moreover）。控制句子长度，避免重复。

예시: Yes, I think bicycles are quite popular in my country. For example, many university students cycle around campus because it's cheap and environmentally friendly. Moreover, in Taipei the public bike system is very convenient — the first 30 minutes are free, so people often use it for short trips.

× Yes I do have a bike when I was a child and the bike also had a lot of memory of me and my dad because he used to told me how to ride a bike and I used to be afraid of riding a bike but ever since my father told me I just started loving.

✓ Yes, I had a bike when I was a child. The bike also holds many memories of me and my dad because he used to tell me how to ride a bike. I used to be afraid of riding, but ever since my father taught me, I started to enjoy it.

错误类型：过去时使用不当。解释：句子描述的是过去的经历，应使用过去时态。原句中混用了现在时（do have）、过去时态错误形式（used to told）和不一致的时态（ever since ... I just started）。建议：将“do have”改为过去式“had”；将“used to told”改为正确的过去习惯用法“used to tell”或更合适的“taught”；把“ever since my father told me I just started loving”改为“ever since my father taught me, I started to enjoy it”，保持时态一致并使用自然表达。

× Yes, a lot of university student they ride a bike in their campus because it's good for the environment and also riding a bike in Taipei City, if you are rent the public bike, it's for free in 30 minutes, so it's quite envir, quite convenient.

✓ Yes, a lot of university students ride bikes on their campus because it's good for the environment. Also, in Taipei City, if you rent a public bike, the first 30 minutes are free, so it's quite convenient.

错误类型：单复数问题（以及其它相关语法问题）。解释："a lot of university student"中的名词应为复数"students"；"ride a bike in their campus"中的冠词与介词不自然，应改为复数并用"on campus"；"if you are rent"是动词形式错误，应为"if you rent"；"it's for free in 30 minutes"表达不自然，改为"the first 30 minutes are free"。建议：将可数名词用复数形式，注意固定搭配（on campus, rent a bike），并使用正确的动词形式和自然的时间/费用表达。
