Bike— Part 1 Báo cáo

Gợi ý: 質問のリピートは避け、短く直接的に答える練習をしましょう。また文法ミス（children → child）を直し、トピック・センテンスを使ってから具体例を一つ加えると良いです。例：過去の所有や頻度、誰と乗っていたか、どんな場所で乗っていたかなどを述べます。

Ví dụ: Yes, I had a bike when I was a child. I used to ride it almost every day around my neighborhood, often with my sister, and I remember practicing tricks in the local park.

Gợi ý: 質問をそのまま繰り返すのは避け、まず意見を述べ（Yes/No/It dependsなど）、次に具体的な理由や例を1〜2文で加えましょう。リンク語（because, for example, however）を使って論理的に展開すると効果的です。

Ví dụ: Yes, I think bikes are quite popular in my country because many people use them for short commutes and exercise. For example, in big cities you often see bike lanes and shared-bike systems that many commuters use.

× Did you have a bike when you were children?

✓ Did you have a bike when you were a child?

The student used 'children' (plural) while addressing a single person; the correct pronoun phrase is 'a child' for one person. Use 'you were a child' to refer to the listener's childhood. Suggestion: when talking about your own or one person's childhood, use 'a child' or 'childhood' rather than 'children'. Note: This matches Grammar Problem Type ID 12 (Incorrect use of pronouns).

× Do you think bikes are popular in your country?

✓ Do you think bikes are popular in your country?

This sentence is grammatically correct. It uses present simple to ask about a general fact and correctly uses the plural 'bikes' and 'are'. No changes needed.
