Bike— Part 1 採点レポート

提案: Give a direct short answer but expand with 2–4 supporting sentences. Include a brief reason, a specific example or memory, and a linking word to connect ideas. Keep it natural and concise (max 5 sentences).

例: No, I didn’t have a bike when I was a child. I grew up in a small apartment and my parents thought it wasn’t safe to ride near the busy road outside, so they never bought one. Instead, I often walked to school with friends or used public transport, which meant I missed out on learning to ride until I was older.

提案: Avoid saying you don’t know. Offer an opinion with a reason and a specific detail or comparison. Use linking words (however, because, for example) and keep the response to 2–4 sentences. This shows fluency and the ability to speculate logically.

例: Yes, I think bikes are becoming more popular in my country because many cities are building bike lanes and people want cheaper, greener transport. For example, in my city you can now rent shared bicycles easily, which has encouraged more commuters to cycle to work.

× No.

✓ No, I didn't.

The question 'Did you have a bike when you were a child?' is in the past simple and expects a full answer. The student's one-word reply 'No.' is a fragment and lacks a verb, so it is a sentence without a verb and unclear. According to the provided list, this is a sentence structure issue (also relates to 'Sentence without a verb'). Correct form: 'No, I didn't.' or 'No, I didn't have one.' Use the auxiliary 'did' plus base verb for past simple negative responses to match the tense of the question.

× I don't know.

✓ I'm not sure.

The question 'Do you think bikes are popular in your country?' asks for an opinion. The student's reply 'I don't know.' is grammatically acceptable but sounds abrupt; a more appropriate and polite response is 'I'm not sure.' This changes present simple negative 'do not know' to a present continuous 'am not sure' to express uncertainty about an opinion. This relates to modal/hedging usage and pragmatic appropriateness rather than a strict grammatical error, so improve by using common opinion hedges like 'I'm not sure' or 'I don't think so.'
