Did you have a bike when you were a child?
スコア: 65.0提案: Your answer is correct but too short and lacks supporting detail. To improve, start with a clear topic sentence, then add 1–2 specific details (where you rode it, who taught you, how you felt) using linking words to make it coherent. Keep it natural and avoid repetition.
例: Yes, I had a bike when I was a child. For example, I used to ride it around my neighborhood park every evening, and my older brother taught me how to balance. I remember feeling very proud when I learned to ride without training wheels.
Do you think bikes are popular in your country?
スコア: 40.0提案: Your answer is too brief and unconvincing. Give a direct opinion and support it with specific reasons or examples, using linking words (because, however, for example). Also avoid short, vague replies; expand to 2–3 sentences to explain why you hold that view.
例: No, I don't think bikes are very popular in my country because most people prefer cars for daily commuting due to long distances and busy roads. However, bicycles are becoming more common in some cities for leisure and exercise, especially among young people.
× No, I don't think.
✓ No, I don't think so.
The original sentence is incomplete; the verb phrase 'think' usually needs an object or complement when used to express opinion in short answers. Adding 'so' completes the idea 'I don't think so,' which correctly conveys that the speaker disagrees or does not believe bikes are popular. Suggestion: use 'I don't think so' for negative short responses, or provide a full clause such as 'No, I don't think bikes are popular in my country.'
× Yes, I had a bike when I was a child.
✓ Yes, I had a bike when I was a child.
This sentence is already correct. It uses past tense consistently ('had' and 'was') to refer to a past situation. No change is needed. Suggestion: keep past tense for memories, and you may add details if desired (e.g., 'Yes, I had a bike when I was a child; it was red and I rode it to school').
