Bike— Part 1 採点レポート

提案: 回答が短すぎて情報がほとんどありません。まず完全な文で答え、簡単な理由や状況を付け加えて会話を豊かにしましょう。具体的には、主語と助動詞を正しく使い（例："No, I didn't."）、なぜ持っていなかったのか、代わりに何をしていたのかなどを一文〜二文で述べ、接続詞（because／so／but）を使って自然につなげてください。

例: No, I didn't. When I was a child my parents couldn't afford a bike, so I usually walked to school or took the bus. However, I learned to ride my friend's bike occasionally during summer holidays.

提案: 肯定だけで終わらせず、意見を補強する具体例や理由を付け加えましょう。まず主張（"Yes, I do."）の後に、理由を述べ（because）、具体的な状況や比較、頻度などの詳細を1〜2文で加えてください。接続詞（because／for example／especially）を使うと論理的で自然に聞こえます。

例: Yes, I do. Bikes are quite popular in my country because many people use them for short commutes and running errands. For example, in cities you can see lots of cyclists during rush hour, and there are also many bike-sharing schemes available.

× No, didn't.

✓ No, I didn't.

The student omitted the subject pronoun 'I' in the short negative answer. In English, short answers normally include the subject and auxiliary verb (e.g., 'I didn't'). We should say 'No, I didn't.' to clearly indicate who is being referred to and to follow standard grammatical structure for short negative responses.

× Yes, I do.

✓ Yes, they are./Yes, they are popular.

The question asks about the general popularity of bikes in the country, so the present simple passive or present simple with plural subject is appropriate. 'Yes, I do' answers a question about the student's personal action or preference (e.g., 'Do you ride bikes?'). For 'Are bikes popular in your country?' a natural answer is 'Yes, they are' or 'Yes, bikes are popular.' This matches subject (bikes) with the correct verb form in present tense.
