Bike— Part 1 채점 보고서

제안: 文法と時制の間違いを直し、自然な英文を作る練習をしてください。具体的には過去の習慣や経験を話すときは過去形を使い、代名詞と冠詞を正しく使うこと（例: "I never had a bike when I was a child."）。さらに、単純な主張だけで終わらせず、理由や簡単な説明（どのように移動していたか、兄弟が持っていたか等）を1〜2文付け足して、答えを豊かにしてください。リンク語（because, so, however）を使って文をつなぐ練習も行ってください。

예시: No, I never had a bike when I was a child because my family lived in a small city and we usually walked or took the bus. However, my older brother had one and I sometimes rode it when I visited him.

제안: 語彙の誤用と曖昧な表現を直してください。まず"Rex"は文脈に合わない語なので削除または正しい語（"bicycles"や"bikes"）に置き換えます。意見を述べた後に具体例や理由（交通事情、環境意識、通勤・通学での利用など）を1〜2文で付け加え、リンク語（because, for example, therefore）でつなげてください。発音やイントネーションにも注意し、自然な会話調で答える練習をしてください。

예시: Yes, I think bikes are quite popular in Japan because many people use them for short commutes and running errands. For example, students and office workers often cycle to the station, and cities provide bike lanes which make cycling convenient and safe.

× No, I never have it when I was child.

✓ No, I never had one when I was a child.

The sentence mixes present tense 'have' with a past time expression 'when I was a child'. Use past tense 'had' to match the past context; also use the indefinite pronoun 'one' or 'a bike' instead of 'it', and include the article 'a' before 'child'. Suggestion: say 'I never had a bike when I was a child.'

× Yeah, in Japan I think Rex is so popular and useful.

✓ Yeah, in Japan I think bikes are very popular and useful.

The original uses 'Rex', which is likely a mistaken noun causing subject-verb mismatch and meaning error. The question asks about 'bikes', so use the plural 'bikes' with plural verb 'are'. Also replace 'so' with 'very' for a more natural collocation. Suggestion: ensure the subject matches the topic and use correct plural verb agreement.
