Bike— Part 1 채점 보고서

제안: 你的回答语法错误且内容不明确。先直接回答问题，再补充简短具体的细节（不超过5句）。注意时态（过去式）和词汇（bike/child）。可以提到何时得到、谁给的、是否常骑、为什么喜欢等，并用衔接词连接。

예시: Yes, I did. I got my first bike when I was seven from my parents, and I rode it almost every day around my neighborhood. Because there were few cars, it felt safe, and I learned to ride without training wheels within a week.

제안: 回答过于简短且缺乏细节。应先给出直接回答，然后用一到两句说明原因或举例，使用连接词使表达连贯。可以提到城市/农村差异、主要用途（通勤/休闲）、共享单车现象等。

예시: Yes, I think bicycles are quite popular. In cities many people use shared bikes for short trips, while in rural areas people often ride bikes for daily errands because they are cheap and convenient.

× Yes, I have a child when I was a child.

✓ Yes, I had a bike when I was a child.

该句存在句子结构和时态错误（对应列表中“Sentence structure errors”）。原句中说话者回答“Did you have a bike when you were a child?”时不应说“have a child”，这既改变了句意又使用了与过去时间状语“when I was a child”不一致的现在时“have”。正确做法是：1) 使用与问题一致的名词“bike”；2) 使用过去时“had”来与过去时间状语一致。改进建议：注意复述问题中的关键词并匹配时间表达（例如过去时间用过去时），多练习用过去时回答关于过去经历的问题。
