自行车— Part 1 評分報告

建議: 语法和词汇错误明显，句子不自然且表达不清。建议：1) 使用正确的时态（过去式）；2) 注意名词选择（bike 而不是 bag）；3) 给出一到两句具体细节（比如谁给的、什么时候得的或用途）。例如可以使用连接词 and/but 来丰富句子，但不要超过五句。

範例: Yes, I had a bike when I was a child. It was a red bicycle my parents bought for me when I was seven, and I used it to ride to my friend’s house every weekend.

建議: 表达含糊且有多处词汇错误（write 应为 ride）；句子不连贯，缺少具体细节。建议：1) 用准确的动词（ride）；2) 用连接词（for example, because）使逻辑更清晰；3) 给出具体场景或原因说明流行的原因或频率。保持回答自然、简洁，不超过五句。

範例: Yes, bikes are quite popular in my country. Many people ride them to work or school because they are cheap and convenient, especially in crowded cities where traffic is heavy.

× Yes, I have two bags when I'm a child.

✓ Yes, I had two bikes when I was a child.

原句有多处错误： 1) 名词复数与单数及词语选择错误：学生说“two bags”，但问题是问是否有自行车（bike），应为“two bikes”。 2) 时态错误：问句使用的是过去时“Did you have... when you were a child?”，回答应使用过去时“had”而不是现在时“have”。 3) 从句时态与主句不一致：从句中“I’m a child”也应改为过去时“I was a child”。 改进建议：注意理解提问时态，保持回答时态一致；仔细听关键词，使用正确名词（bike vs. bag）。

× Yes, sure, we often use. We often write bikes when we go work or go to school. Or sometimes, sometimes we write back.

✓ Yes, sure, we often use them. We often ride bikes when we go to work or go to school. Or sometimes we ride them back.

原句主要问题是动词使用不当： 1) “use” 后缺少宾语，且应指代前文的“bikes”，所以用“use them”或更自然地用“ride bikes”。 2) 动词“write”是拼写错误或误用，正确应为“ride”（骑）。 3) 短语“go work”和“go to school”不一致；英语中通常说“go to work”或“go to school”。 4) “write back”完全不合适，意图应为“ride back”或“ride home/return by bike”。 改进建议：复习常见动词搭配（ride a bike, go to work/school），注意代词宾格（them）和动词拼写。
