Bike— Part 1 채점 보고서

제안: 回答不够直接且时态错误，也缺乏细节。应直接回应过去拥有与否，用过去时，并给出1–2个支持句说明原因或记忆，使用连接词使表达更连贯。比如说明家庭情况、出行方式或特殊回忆。

예시: No, I didn’t have a bike when I was a child. My family couldn’t afford one, so I usually walked to school or took the bus. However, I sometimes borrowed my friend’s bike to ride in the park on weekends.

제안: 回答过于简单且重复否定，缺乏具体理由或例子。应先给出观点，然后用一到两句具体原因或比较来支持，如城市交通、气候或基础设施，并使用连接词如“because”或“however”。

예시: I don’t think bikes are very popular in my country because many cities lack safe bike lanes and traffic can be dangerous. As a result, most people prefer cars or scooters for daily commuting.

× No, I don't have a bike when I travel.

✓ No, I didn't have a bike when I was a child.

问题类型：现在时使用不当。学生回答是在回应“当你是孩子时(when you were a child)”，因此应使用过去时。原句使用了现在时“don't have”和一般现在时的时间状语“when I travel（当我旅行时）”，与提问的时间不一致且改变了意思。建议：将动词改为过去式并与提问的时间一致，使用“didn't have”并把时间短语改回“when I was a child（当我还是个孩子时））”。

× No, I don't think the bikes are popular in my country.

✓ No, I don't think bikes are popular in my country.

问题类型：现在时使用不当/冠词使用不当。原句中定冠词“the bikes”暗示特指某些自行车，但问题是泛指自行车作为一类事物是否流行，应省略定冠词。时态方面，否定现在时“don't think”是可以的，但需调整名词用法以符合习惯表达。建议：将“the bikes”改为复数可数名词的泛指形式“bikes”。
