Bike— Part 1 채점 보고서

제안: 句子时态和语法混乱，表达不自然且重复。回答应先直接回答问题，然后用一到两句简洁具体的细节支持，避免长期时态错误和冗余词汇。可以说明是否学过骑车、父母为什么担心以及现在的情况。

예시: No, I didn't have a bike when I was a child. My parents worried about my safety because our neighborhood streets were busy, so they didn't let me learn to ride. As a result, I still haven't learned to ride a bicycle.

제안: 回答有口语犹豫和重复，时态一致性也需改进。应先给出总体看法，然后用一到两句具体比较（如不同年代的交通方式、原因）并使用连接词使逻辑更连贯。尽量减少填充词“um”“ah”。

예시: Yes, bicycles used to be very popular in my grandparents' generation because they were affordable and practical. However, nowadays electric bikes are more common, especially in cities where people prefer faster, low-effort commuting.

× I don't have a bike when I was a child because I can't ride a bicycle until now and my parents are so afraid of my safety.

✓ I didn't have a bike when I was a child because I couldn't ride a bicycle, and my parents were very worried about my safety.

句子中时态混用不当：主句说“when I was a child”是过去时间，动词应使用过去式，所以“don't have”应改为“didn't have”。表示过去不能骑车，应使用过去式“couldn't”。此外“until now”与整句过去背景不符，应去掉或改为表示过去的短语；“are so afraid of my safety”也应改为过去时并用更自然表达“were very worried about my safety”。建议：在描述过去的事件时，统一使用过去时态；避免把现在时（do/are）与过去时间状语连用。

× To be honest, in the in the in the past, umm at at the age of my grandpa and my grandma, it is popular.

✓ To be honest, in the past, at the time of my grandparents, it was popular.

句子中“in the past”与“at the age of my grandpa and my grandma”都表示过去时间，因此谓语应使用过去式“was”，而不是现在式“is”。另外原句有重复词和赘余口语填充词，应去掉以保持书面或正式口语的清晰。建议：表示过去的习惯或情况时，用过去时（was/were）；说话时注意删除多余重复词和填充词。

× But now electric bicycles are popular.

✓ But now electric bicycles are popular.

此句为陈述现在情况，使用现在时“are”正确，无需修改。解释：‘now’指现在，谓语用现在时态是恰当的。
