自行车— Part 1 評分報告

建議: 回答不符合时态和语法，表达不清晰。应该用正确的时态和完整句子开始（如：Yes, I did / No, I didn't），然后补充细节。注意使用过去时（had/was）和正确的词汇（bike 而不是 back）。建议用1-2句主题句再加1-2句具体细节，控制在5句以内。

範例: No, I didn't have a bike when I was a child. I usually walked to school with my friends, and sometimes I borrowed my neighbor's bike for short rides. I wanted a bike, but my family couldn't afford one at the time.

建議: 回答含糊且有错误词汇（back 应为 bike 或者其他），表意不清。应直接回答（Yes/No），然后给出具体理由和例子，使用连接词如 because 或 for example 来组织句子。保持句子简短且语法正确。

範例: Yes, I think bicycles are quite popular in my country because many people use them for short trips and commuting. For example, in cities there are bike lanes and rental schemes, and students often ride bikes to school to save money and time.

× I don't have back when I was child.

✓ I didn't have a bike when I was a child.

原句句子结构和时态混乱：1) 用了现在时否定短语 "don't have" 但时间状语是过去时（"when I was"），应使用过去时；2) 缺少表示“自行车”的名词"bike"；3) "when I was child" 缺少冠词，应为 "a child"。建议：在谈过去的经历时把动词改为过去式（didn't have），补上缺失名词并使用正确冠词。

× Yes, back is is a good spot.

✓ Yes, bikes are popular here.

原句语义和句子结构不正确：1) 原句使用了不明确的单词 "back"，可能想说 "bikes" 或 "bike"；2) 出现重复单词 "is is"；3) 问句是询问自行车是否受欢迎，回答应与问题对应，用复数或泛指单数并使用适当形容词（popular）而非 "a good spot"（地点/场所的说法不合适）。建议：把主语改为复数 "bikes"，使用现在时复数系动词 "are"，并用准确形容词 "popular"，或说 "Yes, bicycles are popular in my country."
