Bike— Part 1 채점 보고서

제안: Your answer is correct but too short and lacks detail. Start with a clear topic sentence, then add one or two specific supporting details (reason, brief example or contrast). Keep it natural and under five sentences. Use a linking word if you add a second sentence (e.g., "because", "but", "so").

예시: No, I didn't. I grew up in a busy city where parents preferred we walk or take public transport, so they didn't buy me a bike. As a result, I only learned to ride when I was a teenager.

제안: The content is unclear and the linking word "Yet" is misused. Begin with a direct opinion (Yes/No/Somewhat), then explain with specific reasons or examples using proper linking words (e.g., "because", "however"). Keep answers concise and coherent, no more than five sentences.

예시: Yes, I think bikes are fairly popular because many people use them for short trips and exercise. However, in big cities they are less common for commuting due to heavy traffic and limited bike lanes.

× No, I didn't.

✓ No, I didn't have one.

The examiner asked 'Did you have a bike when you were a child?' The student's response 'No, I didn't.' omits the object and can sound incomplete in this context. This is a sentence structure/ellipsis issue related to sentence completeness (maps to 'Sentence structure errors' ID 26). To improve, include the object 'have one' to clearly refer to the bike: 'No, I didn't have one.' This keeps past simple tense consistent with the question.

× Yet, I think so.

✓ Yes, I think so.

The student used 'Yet' incorrectly. 'Yet' is typically used to indicate contrast or in negative questions and is not appropriate as a simple affirmative response. This is a word choice/usage problem mapping best to 'Sentence structure errors' ID 26. Replace 'Yet' with 'Yes' to give a natural affirmative answer: 'Yes, I think so.' This matches the present simple question 'Do you think bikes are popular...' and provides a clear, grammatically correct reply.
