Did you have a bike when you were a child?
スコア: 50.0提案: Answer with “Yes, I did” to match the question’s auxiliary verb. Add a brief specific detail, such as when you rode the bike or what you used it for, to make your response more complete.
例: Yes, I did. I had a small red bike when I was about seven, and I often rode it around my neighborhood with my friends.
Do you think bikes are popular in your country?
スコア: 65.0提案: Your example supports your opinion, but use the natural phrase “take their children to kindergarten by bike” rather than “send their children to a kindergarten on bicycle.” You could also add a reason why bikes are popular, such as convenience or avoiding traffic.
例: Yes, I think bikes are quite popular in my country. For example, I often see parents taking their children to kindergarten by bike in the morning. It’s a convenient way to travel, especially in busy areas.
× Yes, I had.
✓ Yes, I did.
The question uses the past-tense auxiliary did: Did you have a bike? In a short answer, repeat did rather than had: Yes, I did. Use Yes, I had only when had is the auxiliary in the question, as in Had you owned a bike?
× I see many parents who send their children to a kindergarten on bicycle every morning
✓ I see many parents who take their children to kindergarten by bicycle every morning.
Bicycle is a singular countable noun, so on bicycle needs an article: on a bicycle. Alternatively, use the standard transport expression by bicycle, which takes no article. Take their children to kindergarten is also the natural expression for this context.
