自行车— Part 1 評分報告

建議: 用词和语法需要改进，同时回答应更自然并包含更多细节。避免过度自责或消极措辞；用过去时一致表达并保持句子不冗长。可以先直接回答，然后用一两句话简要说明原因或替代交通方式。举例：说明是否曾借用朋友的车或走路上学等。

範例: No, I didn’t. My family couldn’t afford one when I was young, so I usually walked to school or occasionally borrowed a neighbour’s bike.

建議: 回答需要更具体并使用连接词来解释变化原因。先给出直接评价，再用一两句说明为什么流行程度改变（例如交通发展、私家车增多、共享单车出现等），并可比较过去与现在的差异。

範例: I used to think bikes were quite popular when I was a child, but nowadays they are less common because more people can afford cars and public transport has improved, though bike-sharing schemes have made cycling more visible in some cities.

× No, I didn't because my family is so poor that I can't possess a basic a bicycle.

✓ No, I didn't because my family was so poor that I couldn't afford a basic bicycle.

问题类型：主谓时态和助动词不一致（属于主谓一致 / 时态问题）。原句使用了过去时的否定“didn't”，但随后用现在时“is”与情态动词“can't/possess”表达过去情况，时态混用不一致。并且“possess a basic a bicycle”有词序与用词错误：一般用“afford”表示买得起，且有多余的冠词“a”。建议：将描述改为过去时一致的结构，使用过去时的系动词“was”和情态动词的过去式“couldn't”，并用“afford”替换“possess”，删除多余冠词。具体改为："No, I didn't because my family was so poor that I couldn't afford a basic bicycle."（将所有描述过去的动词都改为过去时，确保时态一致）。

× In my opinion, when I was a child it was popular, but now I don't think so.

✓ In my opinion, when I was a child they were popular, but now I don't think so.

问题类型：现在/过去时与代词一致（属于时态和代词使用问题）。原句说“it was popular”指代不明且单数“it”与复数名词“bikes”不一致。因为前面问题是“Do you think bikes are popular...?”，应使用复数代词“they”并用过去时“were”指过去的情况。建议：把“it”改为“they”，并将动词保持过去时，改为"they were popular"。
