Did you have a bike when you were a child?
점수: 65.0제안: Your answer is direct but very short and lacks support. To improve, give a clear topic sentence then add one or two brief supporting details (reason, memory, or contrast). Use a linking word if adding details. Keep it natural and avoid filler sounds like "umm."
예시: No, I didn't have a bike when I was a child. Instead, I usually walked to school because our house was nearby, and my parents preferred me to be careful on the busy roads.
Do you think bikes are popular in your country?
점수: 72.0제안: Your answer addresses the question and gives reasons, but it repeats phrases and has informal fillers. Improve coherence by using a clear topic sentence, avoid repeating "because," and add a specific example or brief comparison. Use linking words (for example, however) if needed, and vary vocabulary (e.g., convenient, efficient). Limit to about 2–4 sentences.
예시: Yes, I think bikes are quite popular in my country because they are a convenient way to get around congested cities. For example, many commuters use motorbikes to weave through traffic, which is faster than driving during rush hour.
× Yes I do, because bikes are very comfortable for my country, because my country is big and when it's traffic, bikes are so so comfortable.
✓ Yes, I think bikes are very convenient in my country because the country is large and when there is traffic, bikes are very convenient.
The original sentence has several grammar issues: 1) 'are very comfortable for my country' uses 'comfortable' incorrectly for vehicles — 'convenient' is more appropriate. 2) 'my country is big' is acceptable but 'the country is large' is more natural. 3) 'when it's traffic' is ungrammatical; the correct structure is 'when there is traffic' using the existential 'there is' (There be issue, ID 3). 4) Repetition of 'because' is redundant; combine clauses for clarity. Suggestion: use 'there is traffic' and replace 'comfortable' with 'convenient' to convey intended meaning; add commas and 'I think' to match the question about opinion.
