Bike— Part 1 採点レポート

提案: Your answer is very short and contains an unnatural word choice (“Yet I did”). Give a direct, natural topic sentence, then add 1–2 brief supporting details using linking words. Be specific (when, what type, who you rode with, or a memory). Keep it under five sentences.

例: Yes, I did. I had a small red bicycle that my parents bought me when I was seven, and I learned to ride it in our neighborhood park. Because I practiced almost every day, I became confident and even joined a weekend ride with friends.

提案: The reply is too brief and lacks explanation. State your opinion clearly, then give specific reasons or examples using linking words (for example, because, since, therefore). Mention who uses bikes, where, or any trends to make it convincing.

例: Yes, I do. Bikes are very popular, especially in cities, because many people use them to commute to work and avoid traffic. For instance, there are now more bike lanes and shared bicycle schemes in major cities, which makes cycling practical and convenient.

× Yet I did.

✓ Yes, I did.

The student used 'Yet' incorrectly at the start of a short reply. 'Yet' is not used as a simple affirmative response to 'Did you...?' and causes a sentence structure error. A correct short affirmative is 'Yes, I did.' Suggestion: use standard short answers for past simple questions: 'Yes, I did' or a full sentence like 'Yes, I had a bike when I was a child.' Additionally, map this error to the provided list as type 26 (Sentence structure errors) because the main issue is incorrect sentence structure/word choice for the reply.

× Yes, I do.

✓ Yes, they are.

The student's reply 'Yes, I do.' is grammatically acceptable in many contexts, but in response to 'Do you think bikes are popular in your country?' it is better to answer about 'bikes' (they) rather than 'I'. The question asks about popularity in the country (general), so a pronoun referring to bikes ('they') or a full sentence is clearer: 'Yes, they are.' or 'Yes, I do think bikes are popular in my country.' This is a pronoun reference/content choice issue mapped to Sentence structure errors (type 26) because the original grammar is not strictly wrong but the reference is awkward. Suggestion: answer with 'Yes, they are.' or 'Yes, I think bikes are popular in my country.'
